Description

A BRAKING SYSTEM FOR A VEHICLETECHNICAL FIELD

[0001] The present subject matter relates, in general, to a braking systems for vehicles and, particularly but not exclusively, to a braking system for a vehicle that enables combination braking through a secondary lever.BACKGROUND

[0002] A braking system in a vehicle provides controlled deceleration and stopping capability to a rider. The braking system allows the rider to control the speed of the vehicle speed and stop it safely by applying braking forces to the rotating wheels or drive components. Modern braking systems typically include several components, such as brake levers or pedals, cable assembly, master cylinder, mechanical linkages, brake pads, discs, drums, etc.

[0003] Two-wheeled vehicles, such as motorcycles and scooters, commonly employ separate brake assemblies for front and rear wheels. The front brake assembly typically utilizes a hand-operated lever mounted on the right hand of the handlebar, which actuates the master cylinder to pressurize brake fluid within the hydraulic braking system, thereby actuating a caliper which clamps against the hydraulic disc brake mounted on the front wheel to decelerate or slow down the vehicle. The rear brake assembly may be controlled either through a foot pedal or a left hand brake lever, and may employ either the hydraulic disc brake or the mechanical drum brake based on the design and cost consideration of the vehicle. The separation of the front and rear brake controls allows riders to apply braking forces to individual wheels according to their riding conditions, traffic situations, and personal preferences.

[0004] Upon actuation of the master cylinder, a braking pressure is developed within the brake fluid by pushing the master cylinder (through the usage of a brake lever). Through the brake fluid, the developed brake pressure gets applied to a brake caliper piston(s) which transfer force to the brake pads of the two-wheeled vehicle, and finally apply the force on arotating disc (directly attached to the wheels) to achieve a braking action to the two-wheeled vehicle. Due to the higher area of the caliper piston(s), a mechanical advantage on the driver applied braking force is achieved.

[0005] For ensuring braking safety of such a two-wheeled vehicle, types of brakes deployed in the vehicle are of key importance. The types of brakes not only determine the overall safety but also affect handling and performance of the vehicle.

[0006] Generally, the braking system includes front and rear brake levers at the handlebar of the vehicle. Often times, one of the two brake ‘levers’ is at the driver’s foot (in the form of a brake pedal). The front brake is actuated using the right hand (RH) lever. The rear brake is actuated either by way of the brake pedal or by a left hand (LH) lever.SUMMARY OF THE INVENTION

[0007] This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[0008] The braking system comprises a primary lever pivoted to a handlebar of the vehicle, wherein the primary lever is operable to actuate a hydraulic braking system of the vehicle to apply braking force to a front wheel of the vehicle. The braking system comprises an L-bracket comprising a first end and a second end, wherein the L-bracket is fixedly attached to a right-hand master cylinder of the hydraulic braking system through the second end of the L-bracket. The braking system comprises a secondary lever comprising a longitudinal body with a first end and a second end, the longitudinal body abutting an actuation pin of the right-hand master cylinder of the hydraulic braking system. The first end of the longitudinal body is pivotally connected to the first end of the L-bracket, and the second end of the longitudinal body is pivotally coupled to a cable assembly, thecable assembly being coupled to a foot pedal or a left hand brake lever of the vehicle operable to actuate the hydraulic braking system. A pivoted end of the primary lever pushes the longitudinal body to pivot about a lateral axis of the second end of the L-bracket which is orthogonal to an axis of rotation of the primary lever to cause the longitudinal body to move the actuation pin to pressurize the right-hand master cylinder upon actuation of the primary lever. Actuation of the foot pedal or the left hand brake lever causes the cable assembly to pull the longitudinal body about the lateral axis of the second end of the L-bracket which is orthogonal to the axis of rotation of the primary lever to cause the longitudinal body to move the actuation pin to pressurize the right-hand master cylinder.

[0009] The braking system of the present invention enables combined braking of both the front and rear wheels using minimal mechanical components, thereby providing a simple and cost-effective braking system.

[0010] The foregoing general description of the illustrative embodiments and the following detailed description thereof are merely exemplary aspects of the teachings of this disclosure and are not restrictive.BRIEF DESCRIPTION OF DRAWINGS

[0011] The present subject matter is now described, in accordance with examples and with reference to the accompanying figures, in which:

[0012] Figure 1 illustrates a perspective view of a braking system for a vehicle, in accordance with an implementation of the present subject matter;

[0013] Figure 2 illustrates a cross sectional view of the braking system, in accordance with an implementation of the present subject matter;

[0014] Figure 3 illustrates an another perspective view of the braking system, in accordance with an implementation of the present subject matter.DETAILED DESCRIPTION OF DRAWINGS

[0015] Two-wheeled vehicles, such as motorcycles and scooters, are equipped with braking systems designed to decelerate or stop the vehicle.The braking system usually includes at least one brake assembly, such as a front wheel brake assembly and a rear wheel brake assembly for a front wheel and a rear wheel, respectively. Each of the front wheel brake assembly and the rear wheel brake assembly is connected to a brake lever for actuation. The brake lever can be connected to the brake assembly in a variety of ways. For example, the brake lever can be connected to the brake assembly by means of a cable. In one example, one end of the cable may be connected to the brake assembly, and the other end of the cable may be connected to the brake lever. This is typically used in a drum brake system. In another example, the brake lever may be connected to the brake assembly through a hydraulic means. This is typically used in a disc brake system. However, a combination of the drum and disc brake system may also be used.

[0016] Generally, the front wheel and the rear wheel are provided with separate braking systems. The two-wheeler braking systems typically include either hand-operated brakes for both the wheels or include a combination of hand-operated and foot-operated brakes. In the latter case, generally, the front wheel brakes are hand-operated, and include a front wheel brake lever mounted on a handle of the two-wheeled vehicle for actuation, whereas the rear wheel brakes may be foot-operated by a rear wheel brake pedal provided near a footrest of the rider.

[0017] In sudden braking events, when the driver applies only the front brake, the vehicle undergoes a significant forward transfer of weight which in turn increases the vertical load on the front wheel, causing sudden jerk to the vehicle. The sudden jerk may affect the ride quality and may disturb the balance and stability of the vehicle leading to an accident.

[0018] Therefore, in practice, riders apply rear wheel brake alone to stop or decelerate the vehicle. However, when the brake is applied abruptly to the rear wheel alone, the weight of the vehicle shifts in the forward direction which in turn diminishes a rear axle weight (RAW), i.e., the normal reaction supported by the ground on the rear wheel, due reduced load on the rearwheel, thereby causing the rear wheel of the vehicle to skid or swing laterally (also known as fishtailing), without achieving the desired deceleration.

[0019] To address the above issues, a combination braking system (CBS) is widely used in two-wheeled vehicles to enable simultaneous actuation of both the front and rear wheel through a single brake lever. The CBS connects the operation of the front and rear brakes via a common brake force transmitting member, such as the rear wheel brake pedal or the rear wheel brake lever typically mounted on the handlebar of the twowheeler. During the operation, when the rider actuates either the rear wheel brake pedal or the rear wheel brake lever, a balanced braking force is applied simultaneously to both the front wheel and the rear wheel, ensuring stability and safety of the vehicle.

[0020] The CBS utilizes an equalizer, a mechanical or hydraulic device, for proportionally distributing the braking force between the front wheel and the real wheel according to a preset braking ratio tailored to the design and dynamics of the vehicle. For example, upon the actuation of the rear wheel brake pedal or the rear wheel brake lever, the equalizer transfers braking force so that roughly 40% is applied to the front wheel and 60% to the rear wheel, depending on the vehicle characteristics. This balanced force allocation improves overall braking efficiency, prevents early skidding or fishtailing of rear tire, and maintains vehicle stability during deceleration.

[0021] However, the conventional CBS often requires numerous components and linkages to connect the rear brake pedals or lever to both the rear brake assembly and the front brake assembly. The numerous components and linkages to implement the CBS not only makes the braking system complex but also increases the weight and the cost of the vehicle.

[0022] Thus, there exists a need for an improved combination braking system that counters the above-mentioned shortcomings associated with the conventional combination braking system.

[0023] To this end, the present subject matter provides techniques for providing a simple, efficient, and cost-effective braking system for a vehicle.

[0024] In accordance with example embodiments, the present subject matter comprises a braking system for a vehicle. The braking system comprises a primary lever, an L-bracket, a secondary lever, and a cable assembly. The primary lever is pivoted to a handlebar of the vehicle. The primary lever is operable to actuate a hydraulic braking system of the vehicle to apply braking force to a front wheel of the vehicle. The L-bracket comprises a first end and a second end. The L-bracket is fixedly attached to a right-hand master cylinder of the hydraulic braking system through the second end of the L-bracket. The secondary lever comprises a longitudinal body having a first end and a second end. The longitudinal body abuts an actuation pin of the right-hand master cylinder of the hydraulic braking system. The first end of the longitudinal body is pivotally connected to the first end of the L-bracket, whereas the second end of the longitudinal body is pivotally coupled to the cable assembly. The cable assembly is coupled to a foot pedal or a left hand brake lever operable to actuate the hydraulic braking system of the vehicle.

[0025] During the actuation of the primary lever, a pivoted end of the primary lever pushes the longitudinal body to pivot about a lateral axis of the second end of the L-bracket which is orthogonal to an axis of rotation of the primary lever to cause the longitudinal body to move the actuation pin to pressurize the right-hand master cylinder. Further, actuation of the foot pedal or the left hand brake lever causes the cable assembly to actuate the longitudinal body of the secondary lever to move the actuation pin to pressurize the right-hand master cylinder.

[0026] The presently disclosed subject matter provides a simple and cost-effective braking system that enables combined braking of both the front and rear wheels using minimal mechanical components. The secondary lever allows both the primary lever and the foot pedal or the auxiliary hand lever to actuate the right-hand master cylinder, thereby reducing system complexity due to elimination of complex linkages. The L- bracket configuration eliminates the need for additional components byproviding both the recess and pivot connection in a single component. Particularly, the configuration of the secondary lever and the L-bracket not only simplifies the braking assembly design but also reduces the components count, manufacturing costs, and overall weight of the braking assembly.

[0027] The above and other features, aspects, and advantages of the subject matter will be better explained with regard to the following description and accompanying figures. It should be noted that the description and figures merely illustrate the principles of the present subject matter along with examples described herein and should not be construed as a limitation to the present subject matter. It is thus understood that various arrangements may be devised that, although not explicitly described or shown herein, embody the principles of the present disclosure. Moreover, all statements herein reciting principles, aspects, and examples thereof, are intended to encompass equivalents thereof. Further, for the sake of simplicity, and without limitation, the same numbers are used throughout the drawings to reference like features and components.

[0028] Figure 1 illustrates a perspective view of a braking system for a vehicle, in accordance with an implementation of the present subject matter.

[0029] As shown in Figure 1 , the braking system 100 for a vehicle (not shown) may include various components arranged to perform a combined braking on both the front and the rear wheels of the vehicle. The vehicle may be a two-wheeler, such as motorcycles and scooters. In one example embodiment, the vehicle may be an electric vehicle.

[0030] In one embodiment, the braking system 100 may include a primary lever 102 that may be pivotally mounted to a handlebar (not shown in the figure 1 ) of the vehicle through a C-clamp 136 using a plurality of bolts 138 that enables rotational movement of the primary lever 102 about a fixed axis perpendicular to the direction of motion of the vehicle. The primary lever 102 may be configured for manual actuation by a rider to apply a braking force on a front wheel of the vehicle. In one example, the primary lever 102may be positioned on right-hand side of the handlebar. In another example, the primary lever 102 may be positioned on a left-hand side of the handlebar.

[0031] In an embodiment, the braking system 100 includes an L-bracket 104. The L-bracket 104 provides a mounting and support to the various components of the braking system 100 (discussed later). The L-bracket 104 has a first end 104a and a second end 104b. The second end 104b of the L-bracket 104 is fixedly attached to the right-hand master cylinder 1 12 of the hydraulic braking system 1 14 through mechanical fasteners or welding. In an embodiment, a hydraulic braking system 1 14 of the vehicle may be fixedly attached to the handlebar through mechanical fasteners or welding.

[0032] The L-bracket 104 may be manufactured from high strength materials, such as steel, aluminum, or high-grade plastic, to provide adequate structural support for the forces transmitted through a secondary lever 102 (elaborated subsequently) during the braking operations.

[0033] In accordance with example embodiments of the present subject matter, the secondary lever 106 serves as a primary force transmission element within the braking system 100 to implement combined braking system (CBS) (as will be apparent from the following description).

[0034] The secondary lever 106 has a longitudinal body 108 having a first end 108a and a second end 108b. The first end 108a of the longitudinal body 108 is pivotally connected to the first end 104a of the L-bracket 104. In an example, the coupling of the secondary lever 106 to the L- bracket 104 may be achieved through a bearing assembly, bushing, or other low-friction pivot mechanism that enables smooth rotational movement. The pivot connection between the first end 104a of the L-bracket 104 and the first end 108a of the longitudinal body 108 allows the longitudinal body 108 to rotate about an axis that may be substantially parallel to the x-axis of the vehicle.

[0035] As described, the hydraulic braking system 1 14 may be positioned on the handlebar, adjacent to the second end of 1 14b of the L- bracket 104. The hydraulic braking system 1 12 may include an actuationpin 1 10 of the right-hand master cylinder 1 12 to allow mechanical input to be applied to the hydraulic braking system 1 12. In accordance with example embodiments of the present subject matter, the longitudinal body 108 is positioned to interface directly with the actuation pin 1 10 of the right-hand master cylinder 112, thereby creating a mechanical linkage between the secondary lever 106 and the hydraulic braking system 1 14.

[0036] In an embodiment, a spherical profile 1 18 may be formed on a surface of the longitudinal body 108 to facilitate contact between the actuation pin 110 and the longitudinal body 108. The spherical profile 1 18 may distribute contact stresses over a larger area compared to flat surfaces, which may reduce wear rate and improve the durability of the secondary lever 106. In one example embodiment, a tip of the actuation pin 1 10 that engages with the spherical profile 118 of the longitudinal body 108 may have a rounded configuration.

[0037] A cable assembly 116 is fixedly attached to the longitudinal body 108. The cable assembly 1 16 is connected to the foot pedal or a left hand brake lever of the vehicle operable to actuate the hydraulic braking system 1 14. The cable assembly 1 16 is pivotally coupled to the second end 108b of the longitudinal body 108. When tension is applied to the cable assembly 1 16 through actuation of either the foot pedal or the left hand brake lever, the pulling force is transmitted to the second end 108b of the longitudinal body 108, causing the longitudinal body 108 to rotate about a lateral axis of the second end 104b of the L-bracket 104 which is orthogonal to an axis of rotation of the primary lever 102. The rotation of the longitudinal body 108 about lateral axis of the second end 104b of the L-bracket 104 causes the longitudinal body to push the actuation pin 1 10 through the engagement of the longitudinal body with the actuation pin 1 10 through the spherical profile 1 18 to actuate the right-hand master cylinder 1 12. The actuation of the righthand master cylinder 1 12 pressurizes brake fluid within the right-hand master cylinder 112 to transmit the braking force on the front wheel of the vehicle.

[0038] In operation, the longitudinal body 108 of the secondary lever 106 is rotated about the lateral axis of the second end 104b of the L-bracket 104 due to actuation of the primary lever 102. When the rider actuates the primary lever 102, the pivoted end of the primary lever 102 pushes the longitudinal body 108 of the secondary lever 106, causing the longitudinal body 108 to rotate about the lateral axis of the second end 104b of the L- bracket 104. As mentioned previously, the rotation of the longitudinal body 108 about the lateral axis of the second end 104b of the L-bracket 104 causes the longitudinal body to push the actuation pin 1 10 through the engagement of the longitudinal body with the actuation pin 1 10 through the spherical profile 1 10 to actuate the right-hand master cylinder 1 12. The actuation of the right-hand master cylinder 1 12 pressurizes brake fluid within the right-hand master cylinder 1 12 to transmit the braking force on the front wheel of the vehicle.

[0039] Thus, the actuation of either the primary lever 102 or the foot pedal or the left hand brake lever activates the hydraulic braking system 114 and applies braking force to the front wheel of the vehicle. This enables a simple arrangement for the combined braking system, thereby eliminating the need for additional linkages to implement the combined braking system.

[0040] In an embodiment, a projection 120 may be formed at the pivoted end of the primary lever 102. The projection 120 may serve as the mechanical interface with the longitudinal body 108 during actuation of the primary lever 102. The projection 120 may be shaped to engage effectively with the longitudinal body 108 when the primary lever 102 is actuated by the rider.

[0041] In one embodiment, a curvature 122 may be formed on the surface of the longitudinal body 108. The curvature 122 may interface with the projection 120 of the primary lever 102 during the actuation of the primary lever 102. In one example embodiment, the curvature 122 may provide smooth contact between the projection 120 and the longitudinalbody, which may reduce wear rate and improve the durability of the primary lever 102.

[0042] In one embodiment, a radius of the curvature 122 on the surface of the longitudinal body 108 is more than a radius of the projection 120 of the primary lever 102. In one example embodiment, the radius of the curvature 122 is 1 .5 times the radius of the projection 120.

[0043] In one embodiment, a recess 130 may be formed in the second end 104b of the L-bracket 104. The recess 130 may be configured to accommodate a mirror assembly of the vehicle. In one example, the recess 130 may enable the braking system 100 to be integrated with existing mirror mounting configurations without requiring modifications to the mirror assembly. It reduces the need for separate mounting structure for the mirror assembly, thereby reducing the cost and the weight of the vehicle.

[0044] In one embodiment, the left hand brake lever may be positioned on the left-hand side of the handlebar.

[0045] Figure 2 illustrates a cross sectional view of the braking system 100, in accordance with an implementation of the present subject matter.

[0046] As shown in Figure 2, the projection 120 is provided on the primary lever 102 to engage with the secondary lever 106. Accordingly, when the rider actuates the primary lever 102, the projection 120 on the primary lever 102 pushes the longitudinal body 108 of the secondary lever 106 to rotate about the lateral axis of the second end 104b of the L-bracket. The rotation of the secondary lever causes the longitudinal body to push the actuation pin 1 10 through the engagement of the longitudinal body with the actuation pin 1 10 through the spherical profile 1 10 to actuate the right-hand master cylinder 1 12. As mentioned previously, the actuation of the righthand master cylinder 1 12 pressurizes brake fluid within the right-hand master cylinder 1 12 to transmit the braking force to the front wheel of the vehicle.

[0047] On the other hand, when the rider actuates the foot pedal or the left hand brake lever, a tension is applied to the cable assembly 1 16 causingthe second end 108b of the longitudinal body 108 to rotate about the lateral axis of the second end 104b of the L-bracket. The rotation of the second end of the longitudinal body 108b causes the spherical profile 110 on the longitudinal body 108 to push the actuation pin 110 to actuate the right-hand master cylinder 1 12. The actuation of the right-hand master cylinder 1 12 may pressurize brake fluid within the right-hand master cylinder 1 12 to transmit the braking force to the front wheel of the vehicle.

[0048] Thus, the secondary lever 106 in combination with the primary lever 102, cable assembly 1 16, and the right-hand master cylinder 1 12 may provide a combined braking system for the front wheel of the vehicle, thereby reducing system complexity and also the manufacturing cost due to elimination of complex linkages.

[0049] In one embodiment, the foot pedal or the left hand brake lever may independently apply brake to the rear wheel of the vehicle.

[0050] Figure 3 illustrates an another perspective view of the braking system 100, in accordance with an implementation of the present subject matter.

[0051] As shown in Figure 3, the cable assembly 1 16 may include a spring member 124 that may be positioned as an intermediate layer within the cable assembly 116. The spring member 124 may be configured to provide return force for the cable assembly 1 16. In one example embodiment, the spring member 124 may enable the cable assembly 1 16 to retract to a resting position after actuation forces may be released. The spring member 124 may facilitate automatic return of the cable assembly 1 16 to a neutral position when cable tension may be removed.

[0052] In one embodiment, the cable assembly 1 16 may include an outer casing that may provide structural support and protection for internal components of the cable assembly 1 16.

[0053] In one embodiment, a torsional spring 126 may be incorporated into the braking assembly 100 to provide return force for the primary lever 102. The torsional spring 126 may be configured to retract the primary lever102 to a resting position after actuation may be released. In some cases, the torsional spring 126 may be positioned to apply rotational biasing forces to the primary lever 102 that may counteract forces applied during manual actuation.

[0054] In one embodiment, the torsional spring 126 may be configured to retract the primary lever 102 to a resting position during the operation of CBS, i.e., when the brake is applied either via actuation of the foot pedal or the left-hand lever. The torsional spring 126 reduces flutter or unintended movement of the primary lever 102 when the primary lever 102 is in resting position.

[0055] In one example embodiment, the torsional spring 126 may have a first end and a second end. The first end of the torsional spring 126 may be fixedly attached to the primary lever 102. The second end of the torsional spring 126 may be mounted to the right-hand master cylinder (112). The torsional spring 126 may be coiled around a fastener assembly 128. The fastener assembly 128 may pivotally connect the primary lever 102 to the right-hand master cylinder 112. In one example embodiment, the first end and the second end of the torsional spring 126 may enable the torsional spring 126 to apply return torque to the primary lever 102 when the primary lever 102 may be displaced from a rest position.

[0056] In another example embodiment, the fastener assembly 128 may provide secure mounting of both the primary lever 102 and the torsional spring 126 to the handlebar. In one example, the fastener assembly 128 may include threaded components that may enable adjustment of the torsional spring tension or the primary lever 102 positioning. The fastener assembly 128 may maintain proper alignment of components while enabling smooth rotational movement of the primary lever 102 during the primary lever 102 actuation.

[0057] In an embodiment, the cable assembly 1 16 may be mounted to a bracket 134. The bracket 134 may secure the cable assembly 116 to the C-clamps 136. For example, the cable assembly 1 16 may be sandwichmounted between the right-hand master cylinder 1 12 and the C-clamps 136 using the plurality of bolts 138. The sandwich mounting allows the braking system 100 to have a compact structure.

[0058] In an embodiment, a slack may be incorporated into the joints connecting the cable assembly 1 16 to the second end 108b of the longitudinal body 108. The slack allows the rider to achieve the desired braking feel by allowing the slight movement and reducing harshness in the brake response.

[0059] In one example embodiment, the bracket 134 may be made up of aluminum, stainless steel, or high-grade plastic.

[0060] In an embodiment, the braking system 100 may also include a brake switch (also known as brake sensor or brake light switch) to detect when a brake is applied by the rider. Thus, when the rider actuates either the primary lever 102 or the foot pedal or the left hand brake lever, the brake switch contacts are closed, and a signal may be generated. The signal generated may be transmitted to an Electronic Control Unit (ECU) of the vehicle. The ECU then generates a signal that the brake is applied by the rider. Thus, the brake switch provides real time feedback to the ECU about the operational state of the braking system 100, thereby improving the safety of the vehicle.

[0061] Although implementations of a braking system are described, it is to be understood that the present subject matter is not necessarily limited to the specific features of the systems described herein. Rather, the specific features are disclosed as implementations for the braking system for two- wheelers.
