The invention discloses a hydraulic energy supply test device with shell oil return pipelines. The hydraulic energy supply test device includes a servo motor, a high pressure pump, a hydraulic oil storing container, a hydraulic oil pressure gauge, a hydraulic oil flowmeter, a first pressure adjusting valve and a second pressure adjusting valve, and further includes a second oil filter, a reflux pipeline hydraulic oil flowmeter, a selection valve, a second control valve and a radiator. Hydraulic oil passes through the second oil filter, the reflux pipeline hydraulic oil flowmeter, the selectionvalve, the second control valve and the radiator to the hydraulic oil storing container to form a high pressure oil reflux pipeline. The hydraulic energy supply test device is further provided with the two shell oil return pipelines connected with a hydraulic motor assembly and a hydraulic pump assembly of a hydraulic energy supply device in an automobile braking system, and the shell oil returnpipelines are in series connection with a shell oil return pressure gauge, a shell oil return hydraulic oil flowmeter, a shell oil return filter and a shell oil return pressure adjusting valve. The shell oil return filter has the functions that firstly, impurities in an oil liquid are removed before shell return oil to the hydraulic oil storing container; and secondly, the shell oil return filteris used for shell grindings test.
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...
