The automobile brake guards against holds the dead (ABS) laboratory bench wheel hydraulic pressure actuation system the development

The this article main solution is in the ABS laboratory bench which at present uses the wheel rotational speed uniformity bad and controls the wheel torque difficult question. This system uses 4 oil motors to actuate four independent wheels, used the slide valve to solve the wheel rotational speed uniformity well; Thus through the hydraulic system pressure the control wheel torque, simulates the automobile to apply the brake the effect difference in the different coefficient of adhesion road surface; Uses the hydraulic pressure and the electric appliance dual over-load protection. This article to this laboratory bench wheel hydraulic pressure actuation system structure, the control design plan has conducted the thorough research, its main innovation spot uses hydraulic transmission way actuation wheel revolving.
