Automatic water cooling system of car brake

Abstract

The invention discloses an automatic water cooling system of a car brake. The automatic water cooling system comprises a water tank, a nozzle, a controller, a temperature sensor, a control valve or / and a water pump, wherein the control valve or / and the water pump is / are mounted on a communication water pipe between the nozzle and the water tank; an input end and an output end of the controller are respectively connected with the temperature sensor and the control valve or / and the water pump; the automatic water cooling system is characterized in that an edge position of a braking bottom plate of the car brake is provided with a mounting hole; the front end of the temperature sensor penetrates through the back end of the mounting hole and is fixed at the outer side of the braking bottom plate through a connection element; the front end of the temperature sensor is inserted into an inner space of a braking drum of the car brake, and a gap of 0.1-10.0mm is formed in an annular inner surface of the braking drum; and the position of the temperature sensor is located at the position which is not contacted with a brake shoe block of the brake and a frictions sheet. According to the water cooling system disclosed by the invention, the temperature is accurately controlled; and the brake is effectively prevented from being burnt and the consumption of cooling water is reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a brake water cooling system for automobiles. Background technique [0002] At present, large passenger cars or trucks are equipped with a brake water cooling system, which is mainly composed of a cooling water tank installed on the car, a water pipe, a control valve and a nozzle. , use cooling water to cool down the brakes of the car, to avoid brake failure caused by excessive temperature of the friction plate caused by long-term braking of the brakes and burning. The control of cooling water is generally divided into manual and automatic. Manual control is to control the closing of the water supply valve in the cab according to the driver's own judgment. The disadvantage is that the timing of the switch is not accurate, and the valve is opened late or closed early. Due to untimely cooling or insufficient cooling, there is still a risk of friction plate burning, and turning on early ...
