Hydraulic pressure adjusting device

Abstract

The invention discloses a hydraulic pressure adjustment device, which comprises the following parts: valve seat, valve lid, end lid, adjustment ring, adjustment valve, non-return seat, non-return cap, non-return valve, adjustment nut lid, first spring, second spring and third spring, wherein the valve seat, valve lid and end lid are connected into assembly cavity sequently; the adjustment valve, non-return seat, non-return cap, non-return valve, adjustment nut lid, first spring, second spring and third spring are set in the assembly cavity; the adjustment ring is set on the periphery of valve seat. The invention is cascaded on the braking oil-way of vehicle to control the oil feeding time difference and pressure difference for vehicle, which shortens the braking distance to avoid the accident.

Description

technical field [0001] The invention relates to a hydraulic pressure regulating device. Background technique [0002] Existing hydraulic braking devices for road machinery (such as automobiles) include electronic anti-lock braking devices and mechanical anti-lock braking devices. The electronic anti-lock braking device has the following problems: one is that the braking distance cannot be shortened, especially when braking on a road with a small friction coefficient, the braking distance will be lengthened; the other is that the electronic anti-lock braking device The body shakes a lot when starting, which aggravates the resonance phenomenon when the vehicle brakes; the third is that there is a complex electronic control system, which is difficult to install and maintain and expensive. Compared with the electronic anti-lock brake device, the mechanical anti-lock brake device is cheaper and simplifies the system, but when braking, the brake oil is allowed to pass through the...

Problems solved by technology

The electronic anti-lock braking device has the following problems: one is that the braking distance cannot be shortened, especially when braking on a road with a small friction coefficient, the braking distance will be lengthened; the other is that the electronic anti-lock braking device The body shakes a lot when starting, which aggravates the resonance phenomenon when the vehicle brakes; the third is that there is a complex electronic control system, which is difficult to install and maintain and expensive

Compared with the electronic anti-lock brake device, the mechanical anti-lock brake device is cheaper and simplifies the system, but when braking, the brake oil is allowed to pass through the rubber body first and expand the output, sacrificing the braking force , can neither shorten the braking distance nor realize the anti-lock function
