Abstract

The invention relates to a hydraulic braking system for solving the problem of inconvenience for exhausting in a traditional vehicle hydraulic brake. The vehicle hydraulic braking system comprises a braking gas supply device, a braking valve, an assistor, a hydraulic control one-way valve and a brake set; the assistor is integrated with a hydraulic control switch valve and a second one-way valve; the braking gas supply device is connected with an inlet of the braking valve; the braking valve, the assistor, the hydraulic control one-way valve and a braking liquid inlet of the brake set are serially connected in sequence; a braking liquid outlet of the brake set is connected with a return port of the assistor; and the hydraulic control switch valve integrated on the assistor uses the assistor for braking the braking hydraulic force of a piston front cavity to control connection and disconnection of a braking liquid oil return access port. In the vehicle hydraulic braking system, the braking gas supply device, the braking valve, the assistor braking liquid outlet, the hydraulic control one-way valve, the brake set and the assistor return port are connected in sequence to finish automatic circulation of braking liquid; the exhausting of the brake set is realized in the circulating process; and the temperature of the braking liquid is lowered to a certain extent.

Description

technical field [0001] The invention relates to a hydraulic braking system, more specifically, to a vehicle hydraulic braking system with automatic circulation exhaust function. Background technique [0002] At present, loaders have been widely used in various projects and mine construction. After the material is filled, its full load weight is about tens of tons, which puts forward high requirements on the braking performance of the vehicle. Especially in mine construction, many Users always transport materials down the mountain, so when the loader goes down the mountain with a full load, the braking system needs to provide a larger braking torque to meet the safety requirements of the whole machine. [0003] However, in the braking system of traditional loaders used by most existing loaders, the brake valve and the booster are connected through an air pipeline to form an air pressure circuit; the booster and the brake are connected through an oil pipeline to form a brake o...
