Description

Technical Field

[0001] This utility model relates to the field of vehicle braking, and in particular to a dual-linkage braking system. Background Technology

[0002] In existing technologies, brake levers on motorcycles, electric vehicles, and other vehicles typically only have a braking function. Current motorcycles or light vehicles usually employ a separate design where the front brake is controlled by the handlebars and the rear brake by the foot. In some situations, when both front and rear wheels need to be braked simultaneously, the rider must use both hands and feet to complete the braking of the entire vehicle, resulting in multiple steps and a long reaction time. Traditional left-front-right-rear hand-controlled linkage structures still cannot meet the requirement of "simultaneous front and rear braking with a single foot pedal." Therefore, a device with a simple structure is needed that can simultaneously actuate both the front and rear brake lines using only the foot brake. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a dual-linkage braking system.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution: A dual-linkage braking system includes a housing, a left brake piston mechanism, and a right brake piston mechanism; the housing has a left brake cavity and a right brake cavity that are separated from each other, and the housing has an axial oil inlet side and an oil outlet side.

[0005] The left brake piston mechanism includes a left brake oil inlet mechanism connected to the left brake lever, a left brake oil outlet mechanism connected to the left brake actuator, and a left brake piston. The left brake oil inlet mechanism and the left brake oil outlet mechanism are respectively connected to the space inside the left brake cavity. The left brake cavity has an oil inlet side and a closed oil outlet side. The left brake piston is inserted into the oil inlet side of the left brake cavity and can move axially back and forth inside the left brake cavity. The right brake piston mechanism includes a right brake oil inlet mechanism connected to the right brake lever, a right brake oil outlet mechanism connected to the right brake actuator, and a right brake piston. The right brake oil inlet mechanism and the right brake oil outlet mechanism are respectively connected to the space inside the right brake cavity. The right brake cavity has an oil inlet side and a closed oil outlet side. The right brake piston is inserted into the oil inlet side of the right brake cavity and can reciprocate axially inside the right brake cavity. The left brake piston has a left drive section on the side away from the left brake cavity, and the right brake piston has a right drive section on the side away from the right brake cavity. The left and right drive sections are located on the same side of the housing and extend outside the housing. The left and right drive sections are connected by a connecting component, which is used to connect with the foot brake. The foot brake drives the connecting component to move axially, which in turn drives the left and right brake pistons to move axially towards the oil outlet side of the housing synchronously. This utility model, by setting pistons in two independent cavities within the housing, and linking the pistons through the connecting component, enables dual-path output by simultaneously driving two pistons with a single foot input, eliminating the need for separate hand and foot operations and shortening the reaction time. Preferably, at least one of the left and right brake fluid delivery mechanisms drives the front brake of the vehicle, and at least one of the left and right brake fluid delivery mechanisms drives the rear brake. The axial layout of the inlet and outlet sides is defined to ensure clear brake fluid flow and avoid cross-contamination within the internal cavity.

[0006] Preferably, the left and right brake chambers are independent of each other. One of the left and right brake oil delivery mechanisms drives the front brake of the vehicle, and the other drives the rear brake. The connecting components are designed to directly receive the foot brake drive, synchronously pushing the dual pistons to ensure that pressure is built up simultaneously for both front and rear braking.

[0007] Preferably, a left spring is installed at the bottom of the left brake chamber on the oil outlet side. The left spring abuts against both the bottom of the chamber and the left brake piston, and is used to reset the left brake piston. Similarly, a right spring is installed at the bottom of the right brake chamber on the oil outlet side. The right spring abuts against both the bottom of the chamber and the right brake piston, and is used to reset the right brake piston. This design ensures automatic return to its original position after the foot brake is released, preventing dragging.

[0008] Preferably, the connecting component is plate-shaped, and the left and right drive parts are bolt-shaped. The left and right drive parts pass through the connecting component, and the connecting component is connected to the foot brake through a connecting rod. The axial movement of the connecting component drives the left and right drive parts to move synchronously axially toward the oil outlet side.

[0009] Preferably, the connecting component is Y-shaped and connected to the foot brake via a linkage. The two forked portions of the connecting component abut against the ends of the left and right drive units, respectively. The axial movement of the connecting component pushes the left and right drive units to move synchronously axially towards the oil outlet side. An alternative solution is provided where the Y-shaped connecting component abuts against the end face of the drive unit, achieving the same synchronous axial movement.

[0010] Preferably, the left brake oil inlet mechanism and the right brake oil inlet mechanism are located in the middle of the housing, and the side walls of the left brake piston and the right brake piston are respectively provided with annular oil grooves. When the brake fluid enters the oil grooves, it drives the left brake piston and the right brake piston to move toward the oil outlet side.

[0011] As a preferred embodiment, this utility model has significant technical effects due to the adoption of the above technical solutions: while retaining the original independent front and rear hand-controlled braking, it only adds a double drive unit and connecting parts extending from the shell, thereby achieving the purpose of single-foot pedaling and simultaneous front and rear braking. The structure is simple, the operation is reliable, the cost is low, and the braking efficiency and driving safety are significantly improved. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0015] Example 1 A dual-linkage braking system, such as Figure 1-3 As shown, it includes a housing 1, a left brake piston mechanism and a right brake piston mechanism; the housing 1 is provided with a left brake inner cavity 2 and a right brake inner cavity 3 that are separated from each other, and the housing 1 has an axial oil inlet side and an oil outlet side.

[0016] The left brake piston mechanism includes a left brake oil inlet mechanism 5 connected to the left brake lever 4, a left brake oil outlet mechanism 6 connected to the left brake actuator, and a left brake piston 21. The left brake oil inlet mechanism 5 and the left brake oil outlet mechanism 6 are respectively connected to the space inside the left brake cavity 2. The left brake cavity 2 has an oil inlet side and a closed oil outlet side. The left brake piston 21 is inserted into the oil inlet side of the left brake cavity 2 and can move axially back and forth inside the left brake cavity 2. The right brake piston mechanism includes a right brake oil inlet mechanism 8 connected to the right brake lever 7, a right brake oil outlet mechanism 9 connected to the right brake actuator, and a right brake piston 31. The right brake oil inlet mechanism 8 and the right brake oil outlet mechanism 9 are respectively connected to the space inside the right brake cavity 3. The right brake cavity 3 has an oil inlet side and a closed oil outlet side. The right brake piston 31 is inserted into the oil inlet side of the right brake cavity 3 and can reciprocate axially in the right brake cavity 3. The left brake piston 21 has a left drive part 22 on the side away from the left brake cavity 2, and the right brake piston 31 has a right drive part 32 on the side away from the right brake cavity 3. The left drive part 22 and the right drive part 32 are located on the same side of the housing 1 and extend out of the housing 1. The left drive part 22 and the right drive part 32 are connected by a connecting part 11. The connecting part 11 is used to connect with the foot brake. The foot brake drives the connecting part 11 to move axially and drives the left brake piston 21 and the right brake piston 31 to move axially towards the oil outlet side of the housing 1 synchronously.

[0017] At least one of the left brake oil delivery mechanism 6 and the right brake oil delivery mechanism 9 drives the front brake of the vehicle, and at least one of the left brake oil delivery mechanism 6 and the right brake oil delivery mechanism 9 drives the rear brake of the vehicle.

[0018] The left brake cavity 2 and the right brake cavity 3 are independent of each other. One of the left brake oil delivery mechanism 6 and the right brake oil delivery mechanism 9 drives the front brake of the vehicle, and the other drives the rear brake of the vehicle.

[0019] A left spring 23 is provided at the bottom of the left brake cavity 2 on the oil outlet side. The left spring 23 abuts against the bottom of the cavity and the left brake piston 21 respectively. The left spring 23 is used to reset the left brake piston 21. A right spring 33 is provided at the bottom of the right brake cavity 3 on the oil outlet side. The right spring 33 abuts against the bottom of the cavity and the right brake piston 31 respectively. The right spring 33 is used to reset the right brake piston 31.

[0020] The left brake oil inlet mechanism 5 and the right brake oil inlet mechanism 8 are located in the middle of the housing 1. The side walls of the left brake piston 21 and the right brake piston 31 are respectively provided with annular oil grooves 12. When the brake fluid enters the oil grooves 12, it drives the left brake piston 21 and the right brake piston 31 to move toward the oil outlet side.

[0021] like Figure 4-5 As shown, a dual-linkage braking system includes a foot pedal, a connecting fork, a left brake piston mechanism, and a right brake piston mechanism.

[0022] The manual braking system can control the left or right brake independently, or be used in conjunction with the foot brake. When the foot pedal is pressed, the connecting fork transmits the pedal force to the left and right brake pistons, causing them to push synchronously, thus activating both the left and right handbrakes.

[0023] Example 2 like Figure 5 As shown in Embodiment 1, the connecting component 11 is plate-shaped, and the left drive part 22 and the right drive part 32 are bolt-shaped. The left drive part 22 and the right drive part 32 pass through the connecting component 11. The connecting component 11 is connected to the foot brake through a connecting rod. The axial movement of the connecting component 11 drives the left drive part 22 and the right drive part 32 to move axially toward the oil outlet side in sync.

[0024] Example 3 Similar to Embodiment 1, the difference is that the connecting component 11 is Y-shaped, the connecting component 11 is connected to the foot brake through a connecting rod, and the two forked parts of the connecting component 11 abut against the ends of the left drive part 22 and the right drive part 32 respectively. The axial movement of the connecting component 11 pushes the left drive part 22 and the right drive part 32 to move axially towards the oil outlet side in sync.

[0025] The connecting part is fork-shaped, and further into a "Y"-shaped structure. One end is connected to the foot pedal, and the other end of the fork is connected to the left brake piston and the right brake piston, respectively.

[0026] This system has a simple structure, is easy to install and maintain, and is suitable for various mechanical devices requiring dual-wheel brakes, showing broad application prospects.
