The invention discloses a hydraulic energy supply testing device with an overflow valve. The hydraulic energy supply testing device with the overflow valve is characterized by comprising 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 hydraulic energy supply testing device with the overflow valve is further provided with a third pressure adjusting valve, a fourth pressure adjusting valve, a fifth pressure adjusting valve and a sixth pressure adjusting valve; a port of a high-pressure oil supply pipeline is connected to a pipeline between the third pressure adjusting valve and the fourth pressure adjusting valve; a pipeline between the third pressure adjusting valve and the fifth pressure adjusting valve is provided with an oil way joint which is connected with a hydraulic motor module in a hydraulic energy supply device; a pipeline between the fourth pressure adjusting valve and the sixth pressure adjusting valve is provided with an oil way joint which is connected with a hydraulic pump module of the hydraulic energy supplydevice in a vehicle braking system; and overflow valves are arranged on the high-pressure oil supply pipeline and a high-pressure oil reflux pipeline. The overflow valves are substantially safety valves for achieving a certain protection effect on pipelines and devices in the pipelines.
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...
