,TagSPECI:TECHNICAL FIELD
The present disclosure relates to braking system for a vehicle. The embodiments disclose a cable or linkage operated brake system of the vehicle.
BACKGROUND OF THE DISCLOSURE
Brake systems are a crucial part in automobiles, machinery and locomotives. Brake systems vary from vehicle to vehicle and use different means to stop a moving vehicle in its track. Many of the road vehicles such as cars, buses and trucks utilize friction braking to stop the moving vehicle when required.
Many of the vehicles such as but not limiting to passenger cars, utilizes hydraulic brake systems to stop the vehicle. Previously in the 18th and 19th century the brake systems were simple in design and brake force was directly linked to the amount of pedal force applied.
In modern times, brake systems have evolved and the vehicles are equipped with precise braking and safety. Some of the brake systems equipped in road vehicles are of hydraulic brake system, disc and drum brake systems, electromagnetic brake and the like.
Many of the vehicles such as but not limiting to passenger cars, good carriers and commercial vehicles are installed with parking brakes for stopping the automobile in a particular gradient or to prevent the vehicle from accidentally moving when parked. Also, parking brake is a safety feature and is a mandatory in many automobile manufacturing industries to equip parking brake in vehicles. Parking brakes equipped in the vehicles are for the stopping the vehicle when in a halt condition or to prevent accidental movement. Parking brakes are also useful to prevent the vehicle from reversing when the vehicle is parked on a gradient.
The parking brake or braking system provided in the vehicles is generally of cable or linkage operated brake systems. Many of the vehicles are provided with mechanical or electronic parking brake system for parking or holding a vehicle on a gradient or when the vehicle is in parked or stopped condition In mechanical parking brake systems, a effort will be applied at parking brake lever end and this effort is magnified by fixed lever ratio or variable lever ratio of parking brake lever which is transmitted through parking brake equalizer mechanism or cross pulling mechanism to the rear brake assembly for parking.
Conventional parking brake equalizer mechanism divides the tension (T) generated by the actuation of the parking brake lever into two parts. The tension (T) is divided by the parking brake equalizer into tension (T/2) and is transmitted to the wheels of the vehicle. Conventional parking brake equalizer mechanism has a load efficiency of 50% and travel efficiency of 100%.
Since the parking brake is generally applied to the rear wheels of the automobile and the brake force applied directly depends on the amount of force applied on the brake lever by the user, extra or strenuous force has to be applied by the user on the parking brake lever.
Figure 1 illustrates prior art of the existing cable or linkage type of brake system (100A). The existing cable or linkage type of brake system (100A) comprises of a brake equalizer unit (1’) provided in-between the floor brackets (2’, 3’). The floor brackets (2’, 3’) are equipped with cable connectors (4’, 5’) through which the cables are crimped or fixed on to the brake equalizer unit (1’). Once the actuation cable (6’) is actuated due to an action on the brake lever (3), the tension force (T) on the actuation cable (6’) actuates the brake equalizer unit (1’) in the direction of the tension force (T). The brake equalizer unit (1’) distributes this tension force (T) to the brake cables (7’, 8’) fixed to the brake equalizer unit (1’). The brake cables (7’, 8’) fixed to the brake equalizer unit (1’) is directly linked to the left hand side and right hand side brakes of the vehicle. Once the tension force (T/2) is acted on the cables (7’, 8’), the brakes will be engaged and the brake is applied to the wheels of the vehicle. Thus the amount of tension force provided to each braking cable (7’, 8’) is considerably lower than the tension force applied by the user on the actuation cable.
In light of foregoing discussion, there is a need to develop a brake system which is sophisticated to the user and to overcome the limitations stated above.

Braking system in vehicles is one of the most important aspect of a vehicle. The brakes equipped in vehicles range from cable or linkage brakes to complex hydraulic braking means with the help of electronics to control and distribute the braking force. In modern day vehicles, variety of safety equipment’s such as Anti-lock brake system (ABS), Electronic brake force distribution (EBD), hydraulic booster brake system etc. are used to improve the stopping power of the vehicle with minimal effort from the user. Almost all the vehicles manufactured are equipped with parking brake systems which use cable or linkage type braking system. When the vehicle is in a parked position or stopped on a gradient, the user needs to use the parking brake so as to prevent the vehicle from accidentally moving without the control of the user. The amount of brake force applied on the parking brakes directly depends on the amount of force applied on the brake lever by the user. The brake lever for applying the parking brake consists of plurality of notches wherein, actuation of the brake lever locks onto any one of the notches. The more the force applied on the brake lever, higher is the level of notch through which the brake gets engaged. For applying the parking brake for a vehicle stopped on a gradient, the force applied by the user has to be high on the brake lever. Hence, there is a need to develop a cable or linkage type braking system which uses minimum effort from the user for applying parking brake to the vehicle.
Referring now to the drawings wherein the drawings are for the purpose of illustrating an exemplary embodiment of the disclosure only, and not for the purpose of limiting the same.
Figure 2 is an exemplary embodiment of the present disclosure which illustrates top view of one embodiment of the brake system (100). The brake system (100) as shown in Figure 3 comprises the first support bracket (4) and the second support bracket (11) are spaced apart from each other and fixed to the vehicle floor (not shown). The first support bracket (4) and the second support bracket (11) has provisions for accommodating first brake cable (1), pair of second cables (6, 7), first brake cable connector (9), second brake cable connectors (10) and a tension adjustment unit (8). The first support bracket (4) houses the first brake cable connector (9) and a tension adjustment unit (8). The second support bracket (11) houses pair of second brake cable connectors (10). A first brake cable (1) having two ends is provided in the system (100), wherein first end of the first brake cable (1) is removably connected to the brake lever (not shown in figure). Second end of the first brake cable (1) passes through the circumference of the first pulley wheel (2) and is removably connected to the tension adjustment unit (8). The first brake cable (1) forms a loop around the first pulley wheel (2) and fixes on to the tension adjustment unit (8). In an embodiment, the tension adjustment unit (8) may be configured with an adjustment nut for adjusting the tension on the first pulley.
Further, a secondary unit (5) is removably attached to the first pulley wheel (2) by the use of suitable fasteners (20). The secondary unit (5) has two ends on to which each of second brake cables (6, 7) are removably attached or crimped to the two ends of the secondary unit (5). The second support bracket (11) houses the second brake cable connectors (10) wherein, each pair of second brake cables (6, 7) passes through the second brake cable connectors (10). The pair of second brake cables (6, 7) passes through the second brake connector (10) and attaches on to the rear brakes of the vehicle. When the brake lever of the vehicle is actuated by the user, the first brake cable (1) removably connected to the tension adjustment unit (8) generates tension force (T) on the first brake cable (1) which dispenses the tension force (T) to the first pulley wheel (2). The tension force (T) generated by first brake cable (1) applies a tension force of (2T) on the first pulley wheel (2). The tension force (T) applied on the brake lever by the user is magnified due to the use of first pulley wheel (2) and fixing the end of the first brake cable to the tension adjustment unit (8).
The tension force (2T) intervening on the first pulley wheel (2) dispenses the forces to the secondary unit (5) linearly. The secondary unit (5) removably connected to each pair of second brake cables (6, 7) receives the dispensed tension forces (T) linearly on to the each cable of second brake cables (6, 7). The tension forces (T) intervening on the each pair of second brake cables (6, 7) due to the actuation of the brake lever (9), applies the suitable pressure for braking the rear wheels of the vehicle. In one embodiment the secondary unit (5) acts as an equalizer to dispense the force on it equally to the second brake cables (6, 7).
Since, the first brake cable (1) is removably connected at either ends, the force required to actuate the brake lever for braking is reduced. The tension force (T) intervening on the first brake cable (1) is dispensed linearly to the first pulley wheel (2) and in turn to the each pair of second brake cables (6, 7) through the secondary unit (5) for braking.
Figures 3a and 3b are exemplary embodiments of the present disclosure illustrating exploded and assembled view of the first pulley wheel (2) and secondary unit (5) of the braking system (100).

The first pulley wheel (1) is removably connected to the secondary unit (5) by using suitable fasteners (20). The first pulley wheel (2) rotates about its central axis due to the action of the at least one first brake cable (1) when the force is applied by the user on the brake lever, thereby tensions the secondary unit (5). The secondary unit (5) distributes the tension to the brakes through the secondary brake cables for applying the brake.
In an embodiment of the present disclosure, the first pulley wheel (2) removably connected to the secondary unit (5) is connected using suitable fasteners (20) so as to allow only rotational movement of the first pulley wheel (2).

The secondary unit (5) in this particular embodiment is a second pulley wheel (13). As shown in the Figure 4 the second pulley wheel (5) is removably connected to the first pulley wheel (2) through a bracket (12). The connecting bracket (12) is fastened at either ends to the axis of the pulley wheel (2) and the second pulley wheel (13). The connecting bracket (12) prevents the second pulley wheel (13) and the first pulley wheel (2) to come in contact during operation. A first brake cable (1) having two ends is provided in the system (100), wherein first end of the first brake cable (1) is removably connected to the brake lever (3), and second end of the first brake cable (1) passes through the circumference of the first pulley wheel (2) and is removably connected to the tension adjustment unit (8). The first brake cable (1) forms a loop around the first pulley wheel (2) and fixes on to the tension adjustment unit (8). In an embodiment, the tension adjustment unit (8) may be configured with an adjustment nut for adjusting the tension on the first pulley.
Further, the second brake cables (6, 7) may be configured to surround the second pulley wheel, and through the second brake cable connectors (10), and then connected to the brakes of the vehicles in one embodiment. In alternative embodiment, one end of the second brake cables (6, 7) may be configured to be removably attached on circumference at either end of the pulley wheel, and other ends connected to the brakes of the vehicle. When the brake lever of the vehicle is actuated by the user, the first brake cable (1) passed through the first pulley wheel (2) and removably connected to the tension adjustment unit (8) generates tension force (T) on the first brake cable (1). The tension force (T) generated by the first brake cable (1) dispenses the tension force (T) to the first pulley wheel (2) wherein, the tension force (T) is magnified to tension force (2T). In one embodiment, the secondary pulley wheel (13) acts as an equalizer unit to dispense the tension force equally to the second brake cables (6, 7).
The tension force (2T) intervening on the first pulley wheel (2) dispenses these forces to the second pulley wheel (13) linearly. The second pulley wheel (13) is removably connected with each pair of second brake cables (6, 7) dispense the tension forces (T) linearly on to the each cable of second brake cables (6, 7). The second brake cables (6, 7) passes through the second brake cable connector (10) and fixes on to the rear brakes of the vehicle. The tension forces (T) intervening on the each pair of second brake cables (6, 7) due to the actuation of the brake lever applies the suitable pressure for braking the rear wheels of the vehicle.
In an embodiment of the present disclosure, the second brake cables (6, 7) can be fixed to the second pulley (13). In the particular embodiment, the second pulley wheel (13) removably connected to the second brake cables (6, 7) on the circumference of the second pulley wheel (13). This arrests the movement of the second pulley wheel (13). The second pulley wheel (13) dispenses the tension forces (T) acting on each of the pair of second brake cables (6, 7) for braking the vehicle.
Figure 5 is another alternative exemplary embodiment of the brake system (100) of the present disclosure. As shown in the FIG. 5 the secondary unit is a support bracket (15). The first pulley wheel (2) and second pulley wheel (13) are removably connected on a shaft (14).

The other side wall (19) houses first brake cable connector (9) and a tension adjustment unit (8). The first brake cable (1) wherein, one end of the first brake cable (1) is fixed to the brake lever and the other end passes through the first pulley wheel (2) is removably connected on to the tension adjustment unit (8). Each pair of second brake cables (6, 7) passes around the circumference of the pulley wheel (13) fixed on the single shaft (14) forming a loop. When a brake lever of the vehicle is actuated by the user, the first brake cable (1) passed through the first pulley wheel (2) and removably fixed to the tension adjustment unit (8) generates tension force (T) on the first brake cable (1) which dispenses the tension force (2T) to the first pulley wheel (2) this results in sliding of first pulley along with the shaft in the slots. The tension force (2T) intervening on the pulley wheels (2, 13) dispenses the tension force (T) to the each of the second brake cables (6, 7) for braking the vehicle, since the sliding of first pulley carries the second pulley along with it.
Thus, actuation of the brake lever actuates the pair of pulley wheels (2, 13) removably connected on the shaft (14) rotates in the direction of the tension force (T). Movement of the pulley wheels (2, 13) fixed to the shaft (14) moves within the slots (16, 17). The fasteners (20) fixed to the single shaft (14) are fastened such that, the single shaft (14) moves only in the slots (16, 17) without any deviations.
It is to be noted that the person skilled in the art may use the same configuration of the braking system in other applications such as machines, industrial equipment’s like cranes, lifts, trolleys and the like not limiting to vehicles and automobiles.

Usage of pulley mechanism in the braking system reduces the effort of the user on the brake lever. With minimum amount of effort from the user, the amount of brake force applied is magnified due to the pulley wheels.
The magnified tension force (2T) developed on the first pulley wheel dispenses the tension forces equally to the cables for braking.
EQUIVALENTS

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
