The invention discloses a hydraulic energy supply test device with a radiator. The hydraulic energy supply test device comprises a servo motor, a high-pressure pump, a hydraulic oil containing container, a hydraulic oil pressure meter, a hydraulic oil flowmeter, a first pressure adjusting valve, a second pressure adjusting valve, a third pressure adjusting valve, a fourth pressure adjusting valve,a fifth pressure adjusting valve and a sixth pressure adjusting valve. The third pressure adjusting valve, the fourth pressure adjusting valve, the fifth pressure adjusting valve and the sixth pressure adjusting valve are in series connection through a hydraulic pipe to form a closed pipeline. The device is characterized by further comprising a second oil filter, a backflow pipeline hydraulic oilflowmeter, a selection valve, a second control valve and the radiator; hydraulic oil passes through the second oil filter, the backflow pipeline hydraulic oil flowmeter, the selection valve, the second control valve and the radiator to reach the hydraulic oil containing container to form a high-pressure oil backflow pipeline, a port of the high-pressure oil backflow pipeline is connected to the pipeline between the fifth pressure adjusting valve and the sixth pressure adjusting valve. The mounting and dismounting procedure is omitted, 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...
