Vehicle brake cooling system

Abstract

The invention relates to brake systems, and provides a car brake and heat radiation system to solve the problem of inconvenient heat radiation of an existing car hydraulic brake. The car brake and heat radiation system comprises a brake gas supply device, a brake pedal, a brake valve, assistors, hydraulic control one-way valves, brake sets, brake liquid storage boxes, an angle sensor, power sources, controllers, two-position two-way solenoid valves, heat radiation fans, heat radiators, second one-way valves, temperature sensors and pressure sensors. A brake liquid outlet of each assistor is connected with a brake liquid inlet of the corresponding brake set through the corresponding hydraulic control one-way valve, and each heat radiator and the corresponding two-position two-way solenoid valve are sequentially connected between a brake liquid outlet of the corresponding brake set and the corresponding brake liquid storage box in series. A brake liquid supplementary opening of each assistor is connected with the corresponding brake liquid storage box. The control ends of the two-position two-way solenoid valves and the angle sensor are connected with the controllers. In the car brake and heat radiation system, in the process of loosening the brake pedal after brake of every time, after the brake pedal resets to a certain angle, the two-position two-way solenoid valves are connected, part of brake liquid in brakes passes through the heat radiators and the two-position two-way solenoid valves to enter the brake liquid storage boxes, and the heat radiation function of the brakes is achieved.

Description

technical field [0001] The invention relates to a brake system, more specifically, to a vehicle brake system with automatic circulation cooling and exhaust functions. 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 oil circuit....
