Problems solved by technology

[0005] When the vehicle is running on a special road surface such as a gentle slope, it is necessary to install a retarder when it needs to realize the slowing function, or to spray water on the brake drum to cool down. The traditional water shower cools down the disc brake, which is easy to cause the brake disc to crack. problems, causing damage to the vehicle, increasing equipment costs and safety risks, and polluting the road environment; when the driving environment is complex, the vehicle needs continuous or repeated braking, and the brakes generate a lot of heat. In severe cases, the braking system will be damaged due to Vehicle accidents caused by tire blowout or fire caused by overheating have traffic safety problems. At the same time, the frequency of brake maintenance is high, which increases the cost of use

Abstract

The application discloses a wet-type multi-disc traveling, parking and buffering integrated braking system and a using method thereof. The braking system comprises a service braking controller, a parking braking controller, a retarding control switch and an electronic control unit. The service braking controller is in control connection with the electronic control unit, the parking braking controller is in control connection with the electronic control unit, and the retarding control switch is in control connection with the electronic control unit. The system adopts a brake with service braking, parking braking and retarding functions; an oil pump and a radiator can guide heat generated by the brake out of the brake for cooling, braking in the driving, parking and retarding states is achieved, the temperature of the brake can be monitored, abrasion of high temperature to a braking system is reduced, the maintenance period of the braking system can be effectively prolonged, maintenancecost is reduced, and the service life of the brake is prolonged. The braking torque of slow braking is adjusted through the set speed, a vehicle can run at a constant speed, and the running safety ofthe vehicle is improved.

Description

technical field [0001] The present application relates to the technical field of brakes, in particular to a wet multi-disc integrated brake system and a method of use thereof. Background technique [0002] The country has higher and higher requirements for the safety and reliability of medium and heavy transport vehicles, and the relevant laws and regulations have gradually been improved, and the safety and reliability requirements for the braking system of the whole machine are also increasing. The brake device is in the form of drum and dry friction plate, which only realizes the functions of driving brake and parking brake. [0003] The national standard GB7258, which came into effect on January 1, 2018, stipulates that from January 1, 2019, dangerous goods transport semi-trailers must be equipped with disc brakes, and from January 1, 2020, three-axle warehouse grid and fence type semi-trailers must be equipped with disc brakes. Install disc brakes; [0004] Our country...
