Problems solved by technology
The disadvantages of this system are: complex structure, difficult manufacturing, installation and maintenance; high price; large body vibration during work; inability to significantly shorten the braking distance; inability to adapt to vehicle load changes
However, due to structural defects, it cannot adapt to vehicle load changes, nor can it shorten the braking distance, without any anti-lock function; its service life is short, and it cannot be used repeatedly for maintenance.
Although the mechanical (MABS) system has low manufacturing cost and is easy to install and maintain, it loses the braking force and does not have the anti-lock function; it cannot shorten the braking distance, and the braking basically does not work on low-adhesion road surfaces; it cannot adapt to the load Variety

Embodiment 1
[0021] Embodiment 1: This compound valve is made up of bonnet 1 and valve body 28 and is about 135cm high, and the special-shaped cylindrical body with width about 60cm. Inside the bonnet there is a space for accommodating the accumulator assembly, the residual pressure regulating valve assembly, the pressure limiting valve gland 20, interconnected holes and an oil inlet passage connecting the brake master cylinder. There are grooves for placing the O-ring 13 and the pressure-limiting valve O-ring 22 on the end face. The components installed in the valve cover are all designed and manufactured by ourselves, except the excess pressure valve seat, which is purchased as a standard part. The valve body 28 has space for accommodating the pressure-limiting valve member and the high-pressure switch valve member, interconnected holes and an oil outlet passage for connecting the brake cylinders. All components in the valve body are designed and manufactured by ourselves. After the bo...

The improved composite hydraulically braking valve for automobile is installed inside the braking oil path between the general pump and the front and back wheel branch pump. The composite hydraulically braking valve consists of residual pressure regulating valve, pressure limiting valve, high pressure switch valve, energy accumulator, exhaust screw plug and other parts, which are installed inside one valve body to form one compact structure. The composite hydraulically braking valve can result in obviously reduced brake distance and smooth and reliable braking. It has high adaptability on automobile load, low cost, long service life and high performance / cost ratio.
Description
technical field [0001] The invention relates to a control device of an automobile hydraulic brake safety system, in particular to an automobile hydraulic brake composite valve. Background technique [0002] At present, the automobile hydraulic brake safety system is mainly an electromechanical integration (ABS) anti-lock braking system and a mechanical (MABS) system. The Mechatronic (ABS) anti-lock braking system is composed of an electronic controller, a wheel speed sensor, an electromagnetic switch valve and a load-sensing proportional valve. It mainly simulates "point braking" braking from the outside of the braking system, that is, the lock-release cycle, so that the vehicle has maneuverability, balance and safety during emergency braking. The disadvantages of this system are: complex structure, difficult manufacture, installation and maintenance; high price; large body vibration during work; inability to significantly shorten the braking distance; inability to adapt to...
