The invention discloses a hydraulic energy supply testing device with oil filters. The hydraulic energy supply testing device comprises a servo motor, a high-pressure pump, a hydraulic oil containingvessel, a hydraulic oil pressure gage, a hydraulic oil flowmeter, a first pressure regulating valve and a second pressure regulating valve, is provided with a third pressure regulating valve, a fourthpressure regulating valve, a fifth pressure regulating valve and a sixth pressure regulating valve, and is further provided with the second oil filter, a backflow pipe hydraulic oil flowmeter, a selector valve, a second control valve and a radiator; hydraulic oil passes through the second oil filter, the backflow pipe hydraulic oil flowmeter, the selector valve, the second control valve and the radiator to reach the hydraulic oil containing vessel to form a high pressure oil backflow pipe, and a port of the high pressure oil backflow pipe is connected to a pipe between the fifth pressure regulating valve and the sixth pressure regulating valve; and the first oil filter is arranged on a pipe between an oil discharge port of a hydraulic motor assembly and an oil absorbing port of a hydraulic pump assembly. By means of the hydraulic energy supply testing device, the mounting and dismounting processes are reduced, and the production cost is greatly reduced.
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...
