Problems solved by technology

[0002] Engineering vehicles such as forklifts or tractors usually use mechanical zipper hand brakes, which are inconvenient to operate, poor parking brake effect, and strong parking brake instability
At the same time, the brake mechanism will cause the risk of slipping, and the service life is short, the failure rate is high, and the parking ability on the slope is poor.
For this reason, some hydraulic control systems have appeared, however, the structure is complex, the cost is high, and the volume is large

Abstract

The invention discloses a hydraulic integrated control system of a vehicle, and the vehicle. The hydraulic integrated control system of the vehicle comprises an oil tank, a parking brake, a braking hydraulic system, a parking braking switch, a pressure switch and a steering hydraulic system; the braking hydraulic system is in communication with the parking braking switch and the pressure switch; in the parking braking state, the braking hydraulic system supplies hydraulic oil to the steering hydraulic system; and in the parking braking release state, the braking hydraulic system supplies the hydraulic oil to the parking brake till the pressure switch detects the situation that the pressure of the parking brake reaches braking release pressure, and then the braking hydraulic system suppliesthe hydraulic oil to the steering hydraulic system. The hydraulic integrated control system of the vehicle integrates the steering function and the parking braking function and has the advantages ofbeing convenient to operate, good in parking braking effect, high in parking braking stability, good in ramp parking capacity, high in safe reliability, long in service life, simple in structure, lowin cost, small in size and the like.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a vehicle hydraulic integrated control system and a vehicle with the vehicle hydraulic integrated control system. Background technique [0002] Engineering vehicles such as forklifts or tractors usually use mechanical zipper hand brakes, which are inconvenient to operate, poor in parking brake effect, and relatively unstable in parking brake. Simultaneously, this brake mechanism will cause the danger of slipping, and the service life is shorter, the failure rate is higher, and the slope parking ability is poor. For this reason, some hydraulic control systems have appeared, however, the structure is complex, the cost is high, and the volume is large. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a hydraulic integrated control ...
