A SYNCHRONIZED CLUTCH SYSTEM FOR A VEHICLE

APPLICANT:

TVS MOTOR COMPANY LIMITED, an Indian Company at: “Chaitanya”, No.12 Khader Nawaz Khan Road, Nungambakkam, Chennai 600 006.

The following specification particularly describes the invention and the manner in which it is to be performed.

 
TECHNICAL FIELD
[0001] The present subject matter relates generally to a clutch system. More particularly but not exclusively, the present subject matter relates to a synchronized clutch system for a vehicle.

BACKGROUND
[0002] Conventionally, vehicles, including personal and commercial vehicles like passenger and cargo variants, come with a foot operated clutch. However, in many multi-wheel vehicles hand operated clutches are also well known. This is true for personal vehicles like motor cycles, scooters, three wheelers, ATVs (all-terrain vehicles) and many commercial vehicles. There are a lot of structural as well as functional difference in working of said two different clutch systems. The decision to provide hand or foot operated clutch system is driven by technical specification of the power unit (engine or electric motor or other power unit meant for propelling vehicle) and/or use of the vehicle. However, it is not easy or known to be desirable to have a system with one type of clutch system to be retrofitted with another or substituting one system with another as that would lead to substantial and expensive alterations for example the removal of hand operated clutch lever and the vehicle is provided only with a foot operated clutch.
[0003] But there are still several users and customers in the market insist on retaining hand operated clutch along even after providing a more common foot operated clutch. Further, the customer also desires to use foot operated clutch or hand operated clutch on need basis. Furthermore, the customers tend to feel fatigue in either operating either of the clutches for longer period due to constant use of hand/ foot for application of force on the clutch during longer operational hours.
[0004] Also, in case of differently-abled driver the clutch handling by one kind of limb, for example the foot, may become impossible thereby preventing such a person from working or using a foot operated clutch in a vehicle. There are also demands for dual actuated clutch system as a fail-safe mechanism in case of failure of one type of actuation component for example, cable in a hand operated clutch. Further, for newer models there is always a challenge for manufacturer to decide whether to give foot operated clutch or hand operated clutch because different users may have personal preference which may affect the sales of a new vehicle with only one type of clutch actuation system. Thus, for varied reasons there is a need in the art for provision of flexibility to customer for switching between both type of clutch operators.
[0005] To address the above issues, it was necessary to develop an efficient dual clutch actuation system which is not only simple in construction, efficient in working, inexpensive to manufacture, easy to service and synchronize appropriately for flexibility in operating. More particularly, the working of the desired synchronized clutch system should be such that it can be operated by hand and foot independently as well as simultaneously without increasing effort of the user. The existing design of vehicles allows only one type of clutch actuation system. This is especially true with constant pressure towards compact design for the engine and surrounding components. cable assembly with clutch.
[0006] Further, the problem of synchronization of both hand and foot operation is also to be addressed because when two separate clutch actuation systems (foot and hand) were used to actuate the same clutch assembly, for example an engine clutch, a reverse action was observed in sync operation. More specifically, when the design integrated two cables to a single cable, a reverse effect was felt, for example, at hand lever when user was actuating the clutch through foot. Also, if cable positions are interchanged mistakenly then it will lead to problems like increase in operating effort and inability to provide required displacement. This will in turn lead to fatal failures such as more wear and tear at engine clutch plates.
[0007] Therefore, a great customer dissatisfaction can be seen because of the inability to operate hand clutch lever and foot operated clutch simultaneously or individually as per their comfort. Therefore, there are multiple related problems to be addressed in a synchronized clutch actuation system including inability to transfer the exact same amount of force/displacement with both cables to actuate the clutch, inability to operate with only single cable without any structural modification, problem of space constraints in radial direction of lever, and the inability to interchange the positions of hand lever clutch cable bullet and the foot clutch pedal cable bullet at engine end. The above problems also contribute to the difficulty in serviceability of the clutch system and vehicle.

DETAILED DESCRIPTION
[00019] In order to achieve one or more of the above-mentioned objectives and other related objectives, the present invention provides a synchronized clutch assembly for a multi wheel vehicle.
[00020] As per one embodiment of the invention, a synchronized clutch system for a vehicle comprises a clutch assembly. The clutch assembly includes a housing, plurality of clutch plates and springs. The clutch assembly is configured to engage and disengage a power transmission in the vehicle. The power transmission may include transmission of power from a power unit to a transmission unit. The power unit can be an internal combustion engine or an electric motor and/or a combination thereof. In one embodiment, the power unit and the transmission assembly are assembled within a common housing. In another embodiment, the transmission unit and the power unit may be installed separately on the vehicle and operably connected using known means. The synchronized clutch system also comprises a clutch actuator assembly which is configured to actuate the clutch assembly. The clutch assembly itself can be those known in the art working in known way. The clutch actuator assembly, in one embodiment of the invention comprises at least a pair of operating members being configured to enable a user of the vehicle to actuate the clutch assembly; at least a cam shaft to operably connect to the clutch assembly; at least a pair of actuator arms attached to the cam shaft; at least a pair of connecting members which are configured to connect each of the operating members to the actuator arms. In the clutch actuator assembly, the cam shaft is configured to be severally and jointly rotated by the pair of actuating arms.
[00021] As per one embodiment of the invention, in the synchronized clutch system the pair of operating members comprises a foot clutch pedal and a hand clutch lever. The clutch assembly can be severally and jointly actuated by the clutch actuator assembly using the foot clutch pedal and the hand clutch lever.
[00022] As per one embodiment of the invention, in the synchronized clutch system, the pair of actuator arms comprises a first lever and a second lever.

[00023] As per one embodiment of the invention, in the synchronized clutch system, the pair of connecting members comprises at least a pair of cables that are operably connected to the first lever and the second lever to the operating members.
[00024] As per one embodiment of the invention, in the synchronized clutch system, each of the cables is attached to the first lever and the second lever using at least a pair of holders. The holders include a pin joint at one end to be pivotably mounted on the first and the second lever using a mounting means and the holders are configured to mount the cables at another end wherein upon exertion of a force from one or more of the operating members, the force travels to the cables and then to said first and second levers through the holders. The holders are oriented in a direction parallel to a displacement of the cables upon exertion of the force. Whenever the cable exerts force on this holder it automatically orients in the direction parallel to the cable travel. When one operating member, such as a hand operated clutch lever or foot operated clutch pedal, is attached with the holder through the cable, the force flows through the holder to that one actuator member only and in turn to a cam shaft. This will provide necessary moment to actuate the engine clutch mechanism. The cables can be placed interchangeably at any position in the holder in any order. This flexibility introduces ease in assembly thereby improving serviceability. While vehicle is driven for long period of time using one operating member for e.g., a hand lever, it introduces large strain on the hand of the driver. Long working hours are common in city traffic conditions as well as long distance driving. In such cases he/she can comfortably switch to foot operated clutch (another operating member). This flexibility to operate engine clutch with foot clutch pedal or hand clutch lever is ergonomically favorable especially when vehicle is being driven for the prolonged period. Also, with this flexibility to operate engine clutch with two different operating members (foot clutch pedal or hand clutch lever) in the same vehicle, a driver would have more comfort and flexibility and avoid muscular strain in hand/leg and avoid and consequent injury or mishap. Further, whenever the hand clutch lever or foot clutch pedal is actuated, it makes cables to displace and displace the holder. The cable displacement makes levers to rotate around the cam shaft. When cam shaft is rotated it actuates further mechanism of engine clutch. Irrespective of which cable displacement is produced, cam shaft will rotate along the same axis thereby actuating the clutching-declutching mechanism. This makes sure that both the holders and the actuating members rotate by same degree angle when force/displacement is given by the cable. This further makes sure that same force/displacement is transferred to the engine clutch from the cam shaft irrespective of the force applied on the hand operated clutch lever or the foot operated clutch pedal. When both the cables are assembled with the holder in any order then both can rotate the cam shaft when force/displacement is applied through any of the cable. This makes sure that the working of the mechanism remains indifferent with the positions of cable interchanged with each other. Further it makes sure indifferent working when only single cable is assembled in either of the holders. This also helps in providing a retrofittable capabilities to the vehicle. For example, a vehicle having an existing clutch system actuated by hand operated clutch lever can be retrofitted using a modified cam shaft with two actuating members (such as levers explained in detailed description), a foot pedal, mounting means for said foot pedal, additional cables and suitable fastening means known in the art. The instant construction does not consume any space in the radial direction of the actuating members hence can be easily placed in the positions where there is space constraint in the radial direction. In another embodiment, when both foot clutch pedal and hand lever clutch are operated, half of the effort is applied by hand clutch lever and remaining half is applied by foot clutch pedal. This decreases effort requirement at hand clutch and foot clutch by half.
[00025] As per one embodiment of the invention, in the synchronized clutch system, the pair of holders comprises a key hole type cut-out for abutting the at least pair of the cables. This makes sure there is no relative motion between a cable bullet and the holder. This protects the cable bullet from wear and tear. Further, when cable is pulled/displaced, the holder will rotate around the hinged point (i.e., the position at which it is rivetted) thereby prohibiting any relative motion between the holder and cable. This will also make it sustain a greater number of cycles thereby making it more durable.
[00026] As per one embodiment of the invention, in the synchronized clutch system, the first lever and the second lever are fixedly attached welded to the cam shaft in a direction substantially perpendicular to an axis of rotation of the cam shaft. The first lever and the second lever are disposed substantially parallel to each other.
[00027] As per one embodiment of the invention, in the synchronized clutch system, the first lever and the second lever are substantially identical in shape and dimensions.
[00028] In another embodiment of the invention, a clutch actuator assembly for actuating a clutch assembly in a vehicle is disclosed. The clutch actuator assembly comprises at least a pair of operating members being configured to enable a user of the vehicle to actuate the clutch assembly; at least one cam shaft to operably connect to the clutch assembly; at least a pair of actuator arms being attached to the cam shaft; at least a pair of connecting members being configured to connect each of the operating members to the actuator arms. In the clutch actuator assembly, the cam shaft is configured to be severally and jointly rotated by the pair of actuating arms upon individual and simultaneous use of the operating members. This is a replaceable structure as it gives flexibility to the user, as if he/she wishes to operate the vehicle solely through hand operated clutch then he/she can remove the foot operated clutch simply by removing the cable connecting the foot operated clutch to the engine. Similarly, this can be done for hand operated clutch.
[00029] In yet another embodiment of the invention, a multi wheel vehicle comprises a frame assembly to provide skeletal support to the vehicle; at least two or more wheels for enabling a motion of the vehicle; a prime mover being configured to propel the vehicle; a transmission assembly being configured to transfer the power from the prime mover to at least one of the three wheels; a clutch assembly that includes a housing, a plurality of clutch plates and springs. The clutch assembly is configured to engage and disengage transmission assembly with the prime mover. The multi wheel vehicle also comprises a clutch actuator assembly for actuating the clutch assembly in the vehicle. The clutch actuator assembly comprising at least a pair of operating members which are configured to enable a user of the vehicle to actuate the clutch assembly. The vehicle comprises at least one cam shaft which is operably connected to the clutch assembly; at least a pair of actuator arms being attached to the cam shaft; at least a pair of connecting members and each of the connecting members is configured to connect each of the operating members to the actuator arms. In the vehicle, the cam shaft is configured to be severally and jointly rotated by the pair of actuating arms upon individual and simultaneous use of the operating members.
[00030] In yet another embodiment of the inventio, a clutch actuator assembly is provided for actuating a clutch assembly in a vehicle, particularly for retrofitting into an existing clutch actuator system with single operating member for actuation. This embodiment includes a first operating member. This first operating member (can be either foot or hand operated) is the one sought to be retrofitted to a second operating member already existing in the vehicle (other than the type of first operating member). The first operating member is also capable of actuating said clutch assembly. The embodiment further has at least one cam shaft, said cam shaft being configured to be operably connected to said clutch assembly and at least a pair of actuator arms which are attached to said cam shaft. The embodiment further includes at least one connecting member, said connecting member being configured to connect said first operating member to one of said actuator arms. In this embodiment, the first operating member, cam shaft, the pair of actuator arms and said at least one connecting member are configured to be retrofitted to said vehicle. The vehicle already comprises a second operating member, said second operating member being configured to actuate said clutch assembly existing in the vehicle. The cam shaft retrofitted into the vehicle with pair of actuator arms is configured to be severally and jointly rotated by said at least a pair of actuating arms and can therefore, actuate the clutch assembly using both the operating members.
[00031] The embodiments of the present invention will now be described in detail with reference to an embodiment in a synchronized clutch system along with the accompanying drawings. However, the disclosed invention is not limited to the present embodiments.
[00032] Figure 1 illustrates a side perspective view of a synchronized clutch system 100 with a clutch actuator assembly 300 in a vehicle 500 (shown in Fig. 11). In the embodiment shown in Fig. 1, the clutch actuator assembly 300 is being used for actuating a clutch assembly (shown in Fig. 4). The clutch actuator assembly 300 comprises a pair of connecting members 304 which contains a pair of cables 304c or hose connections that are operably connected to the pair of actuator arms 303 (shown in Fig. 3). In one embodiment, the actuator arms 303 are in the form of levers 303a and 303b. A pulling effect of these cables 304c via an exerted force applied by the user of the vehicle 500 through at least a pair of operating members 301 (shown in Fig. 11) is utilized to actuate the arms 303. In one embodiment, the operating members 301 for the user may be a hand operated lever 301a (shown in Fig. 11) and a foot operated pedal 301b (shown in Fig. 11). Moreover, the pair of connecting members is not limited to a hydraulic or a mechanical (cable) system, as a combination of both can be used. The pair of cables 304c are abutted to the pair of holders (shown in Fig. 9 and Fig. 10) through a key hole type cut-out 300hk (shown in Fig. 10).
[00033] Figure 2 illustrates a side view of the synchronized clutch system 100 with the pair of operating members 301 for a user of the vehicle 500. The pair of operating members 301 can be a foot clutch pedal 301a and a hand clutch lever 301b. The user of the vehicle 500 can severally and jointly actuate the clutch assembly 200 with the help of clutch actuator assembly 300 i.e., using the foot clutch pedal 301a and the hand clutch lever 301b independently or simultaneously as per desire. It is worth noting that this disclosed configuration ensures that irrespective of the operating member 301 (foot pedal 301b or hand lever 301a) being used by the user the force being applied to the clutch assembly (200) is the required force actuating the clutch assembly (200).
[00034] Figure 3 illustrates a side view of the synchronized clutch system 100 with the pair of actuator arms 303 of the clutch actuator assembly 300. The pair of actuator arms, in this embodiment, comprises a first lever 303a and a second lever 303b attached to a cam shaft 302 (shown in Fig. 4) for transferring the exerted force applied by the user on the operating members 301. The exerted force is transferred from the pair of operating members 301 to the cam shaft 302 with the help of connecting members 304, a pair of holders 300h (shown in Fig. 9 and Fig. 10) and the actuator arms 303. The pair of holders 300h connect the connecting members 304 and the actuator arms 303.
[00035] Figure 4 illustrates a side perspective view of the synchronized clutch system 100 having the clutch assembly 200 and the clutch actuator assembly 300 having various components. Figure 5 illustrates a side view of the synchronized clutch system 100 having the clutch assembly 200 and the clutch actuator assembly 300 with the prime mover 400 of the transmission assembly. Fig.4 and Fig. 5 have been discussed together. The clutch assembly 200 comprises a housing 201 and a plurality of clutches and springs 202 which are configured to engage and disengage the power transmission in the vehicle 500 with help of a prime mover 400. The clutch actuator assembly 300 comprises the pair of operating members 301 which are configured to enable a user of the vehicle to actuate the clutch assembly 200; the cam shaft 302 which is operably connected to the clutch assembly 200; the pair of actuator arms 303 which is attached to the cam shaft 302; the pair of connecting members 304 which connects each of the operating members 301 to the pair of actuator arms 303 wherein the cam shaft 302 is configured to be severally and jointly rotated by the pair of actuating arms 303. In this embodiment the connecting members 304 are connecting cables 304c. The clutch actuator assembly 300 also comprises the pair of holders 300h (shown in Fig. 9 and Fig. 10) which further comprises a pin joint 300hp, a plurality of mounting means 300hm (shown in Fig. 9 and Fig. 10). In one embodiment of the invention, the holders 300h are provided with a key-hole type cut out 300hk for abutting the pair of connecting members 304. The holders 300h are pivotably installed on the actuator members 303, 303a, 303b through said pin joint 300hp. The holders 300h, on one end have holes for pivotable connection to the actuator arms 303 and the other end have key hole shaped opening for abutting the said connecting cables 304c. This enables easy attachment and detachment of the connecting cable 304c to the holders 300h. Further, upon application of forces on the operating member 301 (say hand lever 301a and/or foot pedal 301b), the connecting cables 304c are stretched and holders 300h are aligned in the direction of the force thereby enabling the rotation of the actuator arms 303a, 303b. Further working is explained hereinafter.
[00036] Figure 6 illustrates a side view of the synchronized clutch system 100 showing axis AA and BB that marks the cut section boundary. Figure 7 illustrates a top view of the synchronized clutch system 100 showing sectional area cut across axis AA. Figure 8 illustrates another top view of the synchronized clutch system 100 showing sectional area cut across axis BB. The Figures 6, 7 and 8 have been discussed together for clarity. The synchronized clutch system 100 have the cam shaft 302 being operably connected to the clutch assembly 200 (shown in Fig. 4) is configured to be severally and jointly rotated by the pair of actuating arms 303 which, in this embodiment, are fixedly attached to said cam shaft 302. Further, the bottom portion of the cam shaft 302 is provided with a recess known as pin joint 300hp (shown in Fig. 4) which is configured to receive a pin 302p. When the cam shaft 302 rotates, it rotates the pin 302p in a lateral direction l by actuating the cam shaft 302 which is responsible for transferring the exerted force coming from the pair of operating members 301 to the prime mover 400 with the help of the pair of actuator arms 303 which attaches the cam shaft 302 on one end and the pair of connecting members 304 on its another end with the help of the pair of holders 300h. The cam shaft 302 is designed in such a way that it can rotate freely in response to the force applied on the actuator arms 303. This force is transferred from the holder 300h to the operating members 301 and from operating member 301 to cam shaft 302. This makes cam shaft 302 to rotate and thereby it actuates clutch mechanism at engine end. Both the operating members 301a, 301b are welded to same cam shaft 302 and hence both rotate with the same displacement. The cam shaft 302 rotates in response to cable displacement given by either of the operating members 301. Once displacement is given either by the operating members 301a, 301b, the cam shaft 302 rotates by the same amount thereby producing the same output displacement. This makes it possible to operate the clutch actuator assembly 300 when either of the operating members 301a, 301b is operated.
[00037] Figure 9 illustrates a side perspective view of the connecting members 304 of the clutch actuator assembly 300. Figure 10 illustrates an exploded view of the connecting members 304 of the clutch actuator assembly 300. The Figures 9 and 10 have been discussed together for clarity. The pair of connecting members 304 are attached to the pair of actuating arms 303 with the help of the plurality of mounting means 300hm.
[00038] Figure 11 illustrates a rear-perspective view of a multi wheeled vehicle 500 showing the pair of operating members 301 of the synchronized clutch assembly 100 in an embodiment of the present invention. The pair of operating members 301 in this embodiment include the hand operated clutch lever 301a and the foot operated clutch pedal 301b. The multi wheeled vehicle 500 depicted in this case is a three-wheeler. The foot operated clutch pedal 301b is pivotably mounted using known means in the art such as a clutch mounting bracket 301c, near the floor of the vehicle 500 where the driver’s foot would rest upon being seated. A driver can choose between the foot operated clutch 301b and the hand operated clutch lever 301a depending on his choice and comfort. The novel and inventive actuator assembly and clutch system in the present specification ensures that both the operating members 301 can be operated with ease while exerting equal amount of force on the camshaft 302 to actuate the clutch assembly 200.
