specific Embodiment approach 1

[0008] Specific embodiment one: passive hydraulic braking system, it is made up of one-way overrunning clutch 3, hydraulic pump 4, two brake oil cylinders 2 and oil tank 10, and the oil outlet 7 of two brake oil cylinders 2 is all connected with oil tank 10 After the oil inlets of the two brake cylinders 2 are connected together, they communicate with the oil outlet 8 of the hydraulic pump 4, the oil inlet 9 of the hydraulic pump 4 communicates with the oil tank 10, and the transmission shaft of the hydraulic pump 4 communicates with the oil tank 10. A torque output end of the one-way overrunning clutch 3 is fixedly connected.

[0009] When the passive hydraulic braking system described in this embodiment is applied, the method and working principle of connecting with the braked system are as follows: the torque output ends of the two brake cylinders 2 are relatively fixed on the braked system respectively. Both sides of the brake disc 1, the brake disc 1 is connected with the...

specific Embodiment approach 2

[0011] Embodiment 2: The difference between this embodiment and the passive hydraulic braking system described in Embodiment 1 is that it also includes a relief valve 6 connected to the oil outlet 8 of the hydraulic pump 4 and fuel tank 10 between.

[0012] In practical application, according to the condition of the braked system, the working pressure of the passive hydraulic braking system in this embodiment, that is, the maximum braking torque of the system can be adjusted by adjusting the overflow valve 6 .

[0013] In practical applications, a filter 5 can also be installed between the oil inlet 9 of the hydraulic pump 4 and the oil tank 10 to prevent oil dirt and debris from entering the hydraulic system, thereby ensuring the normal operation of the system.

Abstract

The invention provides a passive brake fluid system, and relates to a brake fluid system. The invention solves the problem that the prior brake fluid system requires a power supply, which causes complexity of structure and waste of energy source. The passive brake fluid system provided by the invention comprises a hydraulic pump (4), two brake cylinders (2) and a tank (10) as well as a unidirectional overriding clutch (3). The oil outlets (7) of the two brake cylinders (2) are communicated with the tank (10). After the oil inlets of the two brake cylinders (2) are connected together, the oil inlets are communicated with the oil outlet (8) of the hydraulic pump (4). The oil inlet (9) of the hydraulic pump (4) is communicated with the tank (10). The transmission shaft of the hydraulic pump (4) is permanently connected with one moment output end of the unidirectional overriding clutch (3). The passive brake fluid system provided by the invention has the characteristics of simple structure, low cost, automatic performance and stop, high reliability, etc., and can be widely used in the existing fields requiring hydraulic braking.

Description

technical field [0001] The invention relates to a hydraulic braking system. Background technique [0002] In the existing hydraulic braking system, the mechanical energy transmitted by the motor is usually converted into hydraulic energy by the hydraulic pump, and the brake is performed through the actuator (mostly the hydraulic cylinder). The current problem is: in the braking process, the outside world must input energy to it, and it is necessary to add a set of power sources specially used to drive the braking device, which not only wastes energy, but also makes the structure of the braking system complex and increases the system cost. Contents of the invention [0003] In order to solve the problems of complex structure and energy waste caused by the existing hydraulic braking system requiring a power source, the invention provides a passive hydraulic braking system without a power source. [0004] The passive hydraulic braking system includes a hydraulic pump 4, two...
