Abstract

The invention discloses a hydraulic energy supply testing device for removing impurities in oil. The device comprises a servo motor, a high-pressure pump, a hydraulic oil placing container, a hydraulic oil pressure gauge, a hydraulic oil flow meter, a first pressure adjusting valve and a second pressure adjusting valve. The device is characterized by being further provided with a second oil filter, a reflux pipeline hydraulic oil flow meter, a selector valve, a second control valve and a radiator; hydraulic oil passes through the second oil filter, the reflux pipeline hydraulic oil flow meter,the selector valve, the second control valve and the radiator to reach the hydraulic oil placing container to form a high-pressure oil reflux pipeline; a first oil filter is arranged on a pipeline between an oil discharge port of a hydraulic motor module of a hydraulic energy supply device in a vehicle braking system and an oil sucking port of a hydraulic pump module; a third oil filter is arranged in the high-pressure oil supply pipeline; and the third oil filter achieves an effect of removing the impurities in the oil before high-pressure oil is conveyed to the hydraulic energy supply device in the vehicle braking system.

Description

technical field [0001] The invention relates to a performance testing device of an automobile braking system, in particular to a hydraulic energy supply testing device of the automobile braking system. Background technique [0002] The braking system of the car is to let the moving car slow down or even stop according to our wishes. The working principle is to convert the kinetic energy of the car into heat energy through friction. The automobile braking system is mainly composed of a hydraulic energy supply device, a control device, a transmission device and a brake. The common brakes mainly include drum brakes and disc brakes. [0003] Drum brakes mainly include brake wheel cylinders, brake shoes, brake drums, friction plates, return springs and other parts. Mainly through the hydraulic device, the friction plate rubs against the inner surface of the brake drum that the old wheel rotates, so as to achieve the effect of braking. When the brake pedal is stepped on, the pi...
