Problems solved by technology

[0002] The braking system of traditional rail transportation equipment is to drive the pump to rotate directly through the wheels, and then brake the equipment through a series of valve groups. Too many valve groups are used, resulting in more leakage points, which increases the difficulty and cost of equipment maintenance. Correspondingly higher
And there is no supplementary pressure measure, resulting in a shorter safe running time of the system

Abstract

The invention discloses a passive hydraulic braking system which comprises an oil pump, a hydraulic bridge, a flow control device, a pressure relief device with the pressure maintaining function, a hydraulic brake, a manual pump and an oil tank. The system has the following technical effects that passive braking can be achieved, and in other words, braking can be achieved without dependence on additionally-provided external power such as a motor; due to the fact that adopted control valve packs are few, leakage of hydraulic oil is relatively small, the maintenance difficulty is further lowered, and cost is effectively reduced; and the reliable pressure supplementing measures are set, so that the safety operation time of the system is prolonged.

Description

technical field [0001] The invention relates to a hydraulic braking system. Background technique [0002] The braking system of traditional rail transportation equipment is to drive the pump to rotate directly through the wheels, and then brake the equipment through a series of valve groups. Too many valve groups are used, resulting in more leakage points, which increases the difficulty and cost of equipment maintenance. also correspondingly higher. And there is no supplementary pressure measure, resulting in a shorter safe running time of the system. Contents of the invention [0003] The object of the present invention is to provide a passive hydraulic braking system. [0004] The technical solution of the present invention is a passive hydraulic braking system, including an oil pump, a hydraulic bridge, a flow control device, a pressure relief device with a pressure maintaining function, a hydraulic brake, a manual pump, and an oil tank; [0005] The inlet and outlet...
