Problems solved by technology

The second type is a dual-pipeline hydraulic braking system with an ordinary master cylinder as the main cylinder. Its structure is relatively complicated, and there are many components, which is not convenient for quick maintenance, and the labor intensity of the driver is relatively high.
Whether it is the first or the second structure, the common problem is: when any component below the brake master cylinder fails, the braking performance of the motor vehicle will be significantly reduced, and the vehicle will not be able to stop within the effective distance
The randomness of failures and the inability of the driver to know the failures in real time have greatly increased the incidence of accidents.

Embodiment Construction

[0017] Referring to Fig. 1, in this embodiment, in the oil circuit from the brake master cylinder 1 to the front and rear brake cylinders 2, 3, the front and rear two sets of pressure-free cylinders are set in parallel for the front and rear brake cylinders 2, 3 Alarm braking device, the device includes:

[0018] The master valve 4 of the oil circuit is arranged at the outlet of the brake master cylinder 1 and is opened and closed synchronously with the operation of the brake master cylinder 1 . Its structural form is shown in Figure 2. This is a piston-type pressure control valve. Its valve chamber 10 is directly connected to the output port of the brake master cylinder 1 through the inlet 9. On its outlet 14 with a sealing ring 15, it is set with The valve core 13 linked by the piston 11 is provided with a piston return spring 12 . When the brake master cylinder 1 starts to work, the pressure oil enters the valve cavity 10 from the inlet 9 of the master oil valve 4, and the...

Abstract

An automatic under-pressure alarming and braking system for motor-driven vehicle is composed of two non-pressure alarming and braking units respectively for front and back braking pumps. Each unit consists of master valve for oil channel, pneumatic alarm valve and the cut-off vacuum braking valve for cutting off the oil inlet valve and hydraulically driving braking pumps. Its advantages are simple structure and high effect.

Description

Technical field: [0001] The present invention relates to motor vehicle safety devices, and more particularly to safety braking systems for motor vehicles. Background technique: [0002] In the existing motor vehicle hydraulic braking system, the use of the dual-pipeline braking system is relatively common. The hydraulic dual-pipe brake system can be roughly divided into two forms. The first type is a hydraulic dual-pipe brake system with a vacuum booster pump as the main cylinder. The utility model has the advantages of simple structure, convenient maintenance, light operation, stable braking performance, low operating intensity for the driver and comfortable operation. The second type is a dual-pipeline hydraulic braking system with a common master cylinder as the main cylinder. Its structure is relatively complex, and there are many components, which is not convenient for quick maintenance, and the labor intensity of the driver is relatively high. Whether it is the firs...
