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

FIELD OF THE INVENTION
[0001] The present invention, in general, relates to a braking system, and in particular relates, to a combined braking system of a vehicle, preferably a two wheeled vehicle.
BACKGROUND OF THE INVENTION
[0002] The two-wheeler automotive business has experienced amazing growth and development in recent decades, both in terms of technology and sales. Two-wheeled vehicles including bicycles, motorcycles, scooters, and light-weight scooters have been able to maintain their popularity among many societal groups as a result of continual technological improvement. In order to meet the needs of various riders, it is necessary for the two-wheeler automotive industry to continuously develop and adapt the components of the two-wheeled vehicles to improve rider safety and comfort.
[0003] In this regard, different kinds of braking systems have been created for two-wheeled vehicles to facilitate smooth braking operations for enhancing the driving experience.
[0004] Conventionally, riders typically only use the rear wheel brake while using the brakes. This practice was developed since it could be uncomfortable for the rider to pull both brake levers at once. Additionally, when the front wheel brake is applied, the front wheel rapidly brakes due to lesser weight on it and weight transfer towards it, which could result in a sudden jerk to the vehicle. The abrupt movement may degrade the ride experience and jeopardize the vehicle's stability and balance, increasing the risk of an accident. On the other hand, it can be necessary to limit the amount of force used to stop the vehicle's back wheel to avoid skidding.
[0005] Traditionally, braking systems that enable simultaneous application of the front and rear brakes with a single brake lever have been used in the art. Such braking systems enable simultaneous actuation of the front brake and the rear brake by use of a single brake lever have been designed to overcome the aforementioned difficulties. With the use of a single brake lever, for instance, the rear wheel brake lever, such a braking system is capable of combining the braking activity of both the front wheel brake and the rear wheel brake. Therefore, such a braking system may enable the application of braking force to both the vehicle's front and rear wheels upon activation of the single brake lever. Consequently, simply by engaging one brake lever, both the front and back wheels can be stopped at the same time.
[0006] A patent application WO2016113756A1 titled “Synchronized braking system for two-wheeled vehicles” describes a system that includes a front wheel brake lever coupled to a front wheel brake by a front wheel brake cable, and a rear control lever capable of synchronously transmitting brake actuating forces to both real wheel brake and the front wheel brake. The rear control lever is movably pivoted and operatively connected to at least one of a rear brake cable and a synchronized brake cable. The rear control lever directly actuates the at least one of the connected rear brake cable and the synchronized brake cable. The other cable is actuated by reaction of the movably pivoted rear control hand lever.
[0007] Further, conventionally, combined braking systems are incorporated into the handlebar brake lever that adds bulk to the handlebars with an intricate system integrated into the brake lever. Further, these systems are implemented by using several brake cable routings within the vehicle, that add clutter on the handlebars. These complex cable routings have higher chances of cable entanglement which adds time and cost for the servicing of the vehicle.
[0008] In addition, the traditional braking systems need a lot of parts and connections to join the combined brake lever to both the front and rear wheel brake assemblies. As a result, the weight of such braking systems may be quite significant. With their numerous components, such bulky and complicated braking systems could also need more frequent maintenance and professional labour. A circumstance like this could raise the expense of the vehicle's maintenance. Additionally, it could be challenging to provide a parking brake system due to a shortage of space on vehicle. In light of this, conventional braking systems may be burdened by high costs and a lack of overall braking effectiveness.
[0009] Therefore, there exists a need to provide a more compact and simple combined braking system that is mountable within the chassis of a vehicle. Further, both a rear and front brake applications are meticulously regulated by the combined braking system of wires, ensuring a symmetrical and balanced braking experience. This system provides significant improvement in braking performance in emergencies.
OBJECTIVES OF THE DISCLOSURE
[0010] A primary objective of the present invention is to overcome the disadvantages of the prior-arts.
[0011] It is an objective of the present disclosure to provide a compact combined braking system that minimizes clutter on the handlebars.
[0012] It is another objective of the present disclosure to provide a more compact and chassis-mounted route for the combined braking system.
[0013] Yet another objective of the present disclosure an improved combined braking system that allows gradual deceleration and prevents abrupt stops that could lead to loss of control.
[0014] Yet another objective of the present invention is to provide an improved combined braking system that minimizes the chances of cable entanglement and simplifies the process of servicing the vehicle's braking system.
[0015] Yet another objective of the present invention is to provide the combined braking system with a double rated restraint unit to ensure rider/user safety during panic braking situation.

[0053] The present disclosure relates to a combined braking system and its method. Fig. 1A illustrates a perspective view of the combined braking system 100 according to an embodiment of the present invention. The combined braking system 100 comprises an outer cover 108, a top cover 110, a combined brake cable 102, a rear brake cable 104, and a front brake cable 106.
[0054] In an embodiment, the top cover 110 is mechanically coupled with the outer cover 108 of the combined braking system 100 using a first plurality of bolts 118. The top cover 110 and the outer cover 108 have a plurality of securing means 124 which are complimentary to each other and the top cover 110 is secured on the outer cover 108 by fixing the first plurality of bolts 118 in the centre of plurality of securing means 124.
[0055] In an embodiment of the present invention, the outer cover 108 has a plurality of mounting means 120 to mount the combined braking system 100 on a vehicle chassis (reference made to Fig 2). The plurality of mounting means 120 includes at least one hole 122 in the centre of each mounting mean to fix the combined braking system 100 to vehicle chassis using a second plurality of bolts (not shown in the figure).
[0056] In an embodiment of the present invention, the first plurality of bolts 118 and the second plurality of bolts may include at least one of an anchor bolt, a carriage bolt, an eye bolt, a hex bolt, a square head bolt, or, in general, bolts. Alternatively, the first plurality of bolts 118 and the second plurality of bolts may include a plurality of nuts or any other type of fasteners that are well known to a person having ordinary skill in the art and are not described here for the purpose of simplicity.
[0057] Fig. 1B illustrates an exploded view of the combined braking system 100, according to an embodiment of the present invention. The combined braking system 100 further includes in addition to Fig. 1A, a hinge 112.
[0058] In an embodiment, the combined braking system 100 is connected to a brake lever (shown in fig. 2) by the combined brake cable 102. The combined brake cable 102 from the brake lever is inserted in the centre hole of the top cover 110 and then connected with the hinge 112 in the slots provided in the centre of the hinge 112.
[0059] In an embodiment of the present invention, the rear brake cable 104 and the front brake cable 106 are capable of synchronously transmitting brake actuating forces to both a real wheel brake and a front wheel brake (not shown in the figure). Additionally, the real wheel brake and the front wheel brake control at least one rear wheel 210 and at least one front wheel 208 (refer to Fig. 2). The front brake cable 106 further includes a restraint unit 114.
[0060] In an embodiment of the present invention, the restraint unit 114 is configured to restraint the front brake cable 106. In an embodiment of the present invention, the restraint unit 114 is a composite spring. In another embodiment, the restraint unit may be any other element performing a similar function.
[0061] In an embodiment, the rear brake cable 104 and the front brake cable 106 are inserted via the top cover 110 into the outer cover 108 and connected to the hinge 112 via a plurality of slots 116.
[0062] Fig. 2 illustrates the placing of the combined braking system 100 on a vehicle 200 which is the two-wheeled vehicle. The vehicle 200 includes a handlebar that further includes the brake lever 202, a front chassis part, and a rear chassis part. The front chassis part contains the at least one front wheel 208 and a rear chassis part contains the at least one rear wheel 210. Further, the at least one front wheel 208 is connected to the combined braking system 100 via the front brake cable 106 and the at least one rear wheel 210 is connected to the combined braking system 100 via the rear brake cable 104.
[0063] In a combined braking mechanism of the combined braking system 100, when a rider/user presses the brake lever, the combined brake cable 102 will be pulled upwards which is mounted in the centre hole of the hinge 112 and the total reaction force of the brake lever will act on the hinge 112 once the hinge 112 moves upwards. Further, hinge 112 is guided in the outer cover 108 for its upward and downward movements.
[0064] Once the hinge 112 starts moving upwards the hinge 112 starts to pull the rear brake cable 104 and the front brake cable 106 mounted on the hinge 112 so a brake force from the hinge 112 starts to distribute equally to the rear brake cable 104 and the front brake cable 106. First, the rear brake cable 104 is pulled with respect to the hinge 112 movement and, then the rear brake is applied to a drum brake which is present in the rear wheel on the left side of the vehicle (not shown in the figure) with respect to the rear brake cable 104 displacement to the hinge 112 movement and the brake lever force.
[0065] In addition, the front brake cable 106 that is attached to the hinge 112 first compensates the hinge 112 displacements by compression of the restraint unit 114 present in the front brake cable 106 which acts as the delay for the front brake as per a combined braking mechanism as the rear brake is applied before the front brake. Further, the restraint unit 114 present in the front brake cable 106 enables the above-mentioned combined braking mechanism (reference made to Fig. 3D).
[0066] In accordance with an embodiment of the present invention, the restraint unit is a composite spring that includes a double-rated stiffness of K1 and K2 to transfer a specific braking force in a plurality of braking conditions. Further, the K2 portion is stiffer than the K1 portion of the restraint unit 114.

[0067] In an embodiment of the present invention, the plurality of braking conditions is of three types i.e. partial braking condition, normal braking condition, and panic braking condition. In the partial braking condition, when the brake lever is pressed, the hinge112 starts to move upwards and only compresses the K1 portion of the restraint unit 114 completely but there is no movement in the front brake cable 106Further, In the normal braking condition, when the brake lever pressed then hinge 112 starts to move upwards, and the restraint unit 114 K1 portion is completely compressed and it also pulls the front brake cable 106, but the K2 of the restraint unit 114 remains same. Because the Brake force to Compress K2 is less. Furthermore, in the panic braking condition when the Brake lever is pressed then hinge 112 starts to move upwards, the restraint unit 114 K1 portion is completely compressed and K2 is compressed in half, it also pulls the front brake cable 106. Because the Brake force to Compress K2 is close to Equal in the panic braking condition.
[0068] Now refer to Fig. 3 which illustrates different elements of the combined braking system 100 (reference have been made to Fig. 1A and 1B), according to an embodiment of the present invention. Fig. 3A discloses the top cover 110 which is configured to secure the outer cover 108 of the combined braking system 100. Additionally, it works as a stopper for the maximum upper limit movement of the hinge 112 and it also acts as protection to the combined braking mechanism from dust and other foreign particles of the environment, which is very important for smooth and continuous execution of the combined braking mechanism.
[0069] Fig. 3B illustrates the outer cover 108 of the combined braking system 100. The outer cover 108 acts as a sliding support to the hinge 112. Further, the hinge 122 is guided in the inner surface of the outer cover 108 when the hinge 112 moves upward and downward concerning the combined brake cable 102 movement actuated by the pressing of the brake lever 202.
[0070] Fig. 3C illustrates the hinge 112 of the combined braking system 100. It is configured to provide a guide for the rear brake cable 104 and the front brake cable 106. Further, it is moving upward and downward in order to apply an appropriate brake force on the at least one front wheel 208 and the at least one rear wheel 210 using the rear brake cable 104 and the front brake cable 106. In addition, the hinge 112 also executes delay application for the front brake application.
[0071] Fig. 3D illustrates the restraint unit 114 of the combined braking system 100. The restraint unit 114 is configured to restraint the front brake cable 106 in order to delay the front brake in the combined braking mechanism. In another embodiment, when the rider/user presses the brake, the rear brake is to engage first before the front brake starts engaging in the combined braking system 100. The restraint unit 114 is used to ensure the delay for the front brake application. In an embodiment of the present invention, the restraint unit 114 is a composite spring that includes a double-rated stiffness of K1 and K2 to transfer a specific braking force in the plurality of braking conditions. Further, the K2 portion is stiffer than the K1 portion of the restraint unit 114.
[0072] Fig. 4 illustrates a method 400 of the combined braking mechanism. The method starts at step 402 and terminates at step 414. In an embodiment, the method 400 is iteratively repeated a plurality of time, as per the requirements of the combined braking mechanism.
[0073] At step 402, the rider/user presses a brake lever in order to provide a brake command a combined braking system 100. In the next step 404, a combined braking cable 102 is pulled when the brake lever is pressed in the method step 402. Further, at step 406, a hinge 112 is moved upward in response to the pulling of the combined braking cable 102.
[0074] At next step 408, a rear brake cable 104 and a front brake cable 106 are pulled in response to the upward movement of the hinge 112.
[0075] At the next step 410, a rear brake is applied to the drum brake which is present in the rear wheel 210 on the left side of vehicle 200 with respect to the rear brake cable 104 displacement to the hinge 112 movement and the brake lever force.
[0076] In another simultaneous step 412 of method step 410, the front brake cable 106 which is attached to the hinge 112 will first compensate for the hinge 112 displacement by compression of a restraint unit 114 present in the front brake cable 106 which acts as the delay for the front brake as per the combined braking mechanism, so the brake force is applied on the rear wheel 210 before the front wheel 208.
[0077] In accordance with an embodiment of the present invention, the restraint unit 114 is a composite spring that includes a double-rated stiffness of K1 and K2 to transfer a specific braking force in a plurality of braking conditions. Further, the K2 portion is stiffer than the K1 portion of the restraint unit 114.
[0078] In an exemplary embodiment of the present invention, the plurality of braking conditions is of three types i.e. partial braking condition, normal braking conditions, and panic braking condition. In the partial braking condition, when the brake lever is pressed, then the hinge112 starts to move upwards and only compresses the K1 portion of the restraint unit 114 completely but there is no movement in front brake cable 106. Further, In the normal braking condition, when the brake lever pressed then hinge 112 starts to move upwards, and the restraint unit 114 K1 portion is completely compressed and it also pulls the front brake cable 106, but the K2 of the restraint unit 114 remains same. Because of the brake force to Compress K2 is less. Furthermore, in the panic braking condition when the brake lever pressed then hinge 112 starts to move upwards, and the restraint unit 114 K1 portion is completely compressed and K2 is compressed half, it also pulls the front brake cable 106. Because of the brake force to Compress K2 is close to Equal in the panic braking condition.
[0079] Further, at the last step 414, a front drum brake present in at least one front wheel 208 is applied by brake cable displacement concerning the hinge 112 movement and brake lever force.
[0080] In an advantageous embodiment, the present combined braking system 100 provides both the rear and front brake applications that are meticulously regulated by a system of wires, ensuring a symmetrical and balanced braking experience. The incorporation of the restraint unit 114 i.e. the composite spring, in the combined braking system 100 guarantees a smooth and responsive braking action, allowing for gradual deceleration and preventing abrupt stops that could lead to loss of control.
[0081] In another advantageous embodiment, the combined braking system 100 of the present invention contributes to a sleek and uncluttered design that ensures that the rider's handgrip area remains clean and free from excessive mechanical parts, thus providing a more comfortable and natural riding experience.
[0082] In an additional advantageous embodiment of the present invention, the combined braking system 100 provides improved braking efficiency by allowing the rider/user to apply both the front and rear brakes simultaneously with ease. Further, the combined braking system 100 significantly reduced the stopping distance and enhanced overall safety. The enhanced braking performance by using the combined braking system 100 is helping in avoiding emergencies such as accidents.
[0083] In an advantage, the combined braking system 100 simplifies the brake cable routing within the vehicle, making it not only more efficient from a manufacturing perspective but also ensuring that the vehicle's maintenance remains hassle-free.
