Described commutator two ends have left bulb and the right bulb that promotes deflecting roller deflection; The limit position of the left steering bulb of described commutator is provided with left catch; The limit position of the right steering bulb of commutator is provided with right catch; Described stand is provided with inductor, and left catch is connected with inductor with right catch.Inductor was received signal when the left steering bulb touched left catch in the limit on the left position; Signal is controlled the steer motor backward rotation after treatment; Inductor was received signal when the right steering bulb touched right catch in the limit on the right-right-hand limit position; Signal is controlled steer motor after treatment and is changed the direction rotation once more, so repeatedly.
Being preferably described inductor is connected with controller.The rotation direction and the stroke of control steer motor behind the inductor signal accepted in control.
Being preferably described steering pump motor is speed-adjustable motor.The pump oil speed that can regulate steering pump is output oil pressure.
Being preferably described frequency variator is connected with speed-adjustable motor.The rotating speed of frequency variator simulated engine is realized frequency conversion, the rotating speed of may command speed-adjustable motor.
Be preferably the utility model and also comprise a protractor, described protractor is connected with oil can, in order to the test oil liquid temp.
Be preferably the protractor of described protractor, can conveniently observe and write down oil liquid temperature for the band temperature display.
The rotating shaft that is preferably described steer motor is connected with the steering controlling shaft of commutator with flexible axle.Flexible axle makes that the control of commutator is more smooth and easy, and it is fixing that steer motor is convenient on stand.
The rotation speed operation that the steering pump motor is set through frequency variator during test drives steering pump pump oil; The fluid that turns to of output certain pressure is input to commutator through high-pressure oil pipe; Steer motor drives commutator steering controlling shaft left rotation and right rotation; Touch left catch when the commutator bulb turns round to the limit on the left position, turn round in the other direction through controller control steer motor behind the inductor output induced signal, realize the direction running to the right of commutator bulb; The commutator bulb turns round and touches right catch to the limit on the right-right-hand limit position, and this process is a work cycle of commutator.
Before test, must measure the turbidity test of commutator, oil pipe, oil can, steering pump in advance, guarantee the turbidity test requirement all up to specification of component; The running time of steering system and work cycle need and actual conditions are complementary.
The utility model can effectively be verified real-world operation working state, shortening test period, the reduction experimentation cost of steering pump, has avoided defective steering pump to install on the automobile, has improved traveling security.
