The invention discloses a double-hydraulic-pressure-gauge hydraulic energy supply test device. The device includes a servo motor, a high-pressure pump, a hydraulic oil container, a hydraulic oil pressure gauge, a hydraulic oil flow meter, a first pressure regulating valve and a second pressure regulating valve. The device is characterized in that the device is further provided with two shell oil return pipes which are connected with a hydraulic motor assembly and a hydraulic pump assembly of a hydraulic energy supply test device in a vehicle brake system; each shell oil return pipe is connected in series with a shell oil return pressure gauge, a shell oil return hydraulic oil flow meter, a shell oil return filter and a shell oil return pressure regulating valve; and second hydraulic oil pressure gauges are respectively arranged at the ports of the pipes connected with the hydraulic energy supply test device in the vehicle brake system. The test system simulates the working environmentof the hydraulic energy supply test device in the vehicle brake system in an all-around manner. The performance indexes of the hydraulic energy supply test device in the vehicle brake system are detected before installation. The hydraulic energy supply test device is installed on a vehicle body only when the hydraulic energy supply test device is proved to be qualified. Therefore, the number of steps of assembly and disassembly is 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...
