Magneto-rheological balance suspension with controllable transmission torque and its control method

Abstract

The invention discloses a transmitted torque controllable magnetorheology balanced suspension and a control method of the magnetorheology balanced suspension. The transmitted torque controllable magnetorheology balanced suspension mechanism is composed of a torsion rod spring, a connecting mechanism, a swing arm and a reciprocating type magnetorheology damper; the swing arm is formed by two weldedsteel plates, and thus one end of the swing arm is conveniently connected with a rear suspension, and the other end of the swing arm is connected with the torsion rod spring through the connecting mechanism; the reciprocating type magnetorheology damper is composed of a symmetrical fan-shaped cavity filled with magnetorheology liquid, a rotor assembly provided with blades and a stator assembly provided with the blades; and the connecting mechanism is connected with the swing arm and the torsion rod spring, and thus interconversion is conducted on twisting motion of the torsion rod spring androtating of the swing arm. According to the transmitted torque controllable magnetorheology balanced suspension and the control method of the magnetorheology balanced suspension, the torque transmitted by the balanced suspension can be controlled in a certain range by connecting a front suspension and the rear suspension of the vehicle, thus the ground attaching performance and the loading capacity can be improved in the balanced suspension, and meanwhile the smooth performance of the vehicle can be improved.

Description

technical field [0001] The invention relates to a balance suspension, in particular to a magneto-rheological balance suspension with controllable transmission torque and a control method thereof. Background technique [0002] During the driving process of the vehicle, due to the uneven road surface, it will cause the phenomenon of tire jumping and wheel suspension. If the steering wheel encounters this situation, the handling ability of the vehicle will be reduced, and if the driving wheel encounters this situation, it will not be able to generate enough driving force. In order to improve the vehicle’s ground performance and load capacity, Many heavy vehicles use a balanced suspension, which can effectively prevent the above situation from happening. The balanced suspension can make the load distribution between the axles reasonable, and enhance the vehicle's ground performance and load capacity. [0003] Although the existing balanced suspension can overcome the above-men...

Problems solved by technology

[0003] Although the existing balanced suspension can overcome the above defects, the torque transmitted by the balanced suspension cannot be controlled, so there are certain disadvantages

If the torque transmitted by the balance suspension is too small, the function of the balance suspension will not be obvious, so that the function of the balance suspension will not be fully utilized, and the expected effect of the vehicle will not be realized. If the transmission torque of the balance suspension is too large, the suspension The jumping of the frame is aggravated, and it is easy to produce an impact on the suspension

When the suspension at one end of the balanced suspension receives a large impact from the ground, the impact of the suspension will cause the balanced suspension to transmit a large torque to the suspension at the other end. Not only that, but due to the linkage effect of the balance suspension, the pitch angle of the vehicle will increase during acceleration and braking, thereby reducing the ride comfort of the vehicle
