The active damping function is realized through an electromagnetic control mode, the reaction speed is high, and the damping effect can be further improved. In addition, the distance between the first coil 5 and the second coil 6 can be smaller, so that the current input into the two coils can be reduced under the condition that the attraction force (or the repulsion force) generated by the two coils is the same, and further the power consumption is reduced. In addition, first coil 5 sets up on first backup pad 2, and second coil 6 sets up on spring 4, need not additionally to set up corresponding bearing structure and can realize the installation of first coil 5 and second coil 6 on current suspension 100, and then can reduction in production cost, does benefit to the production management and control.
The first coil 5 is insulated from the first support plate 2, and the second coil 6 is insulated from the spring 4.
It should be understood that the energizing of the respective coil includes energizing, de-energizing, and energizing current magnitude and direction. Wherein by controlling the current direction of the first coil 5 and the second coil 6 simultaneously, the two coils can be made to repel each other to stretch the spring 4 or attract each other to compress the spring 4; the adjustment of the compression amount and the tension amount of the spring 4 is realized by controlling the current magnitude of the first coil 5 and the second coil 6. Therefore, the posture of the suspension system can be kept in a designed state under any load of the vehicle, and the riding comfort of the vehicle is improved.
