Below in conjunction with accompanying drawing specific implementation process of the present invention is described further.

Caused between sprung weight (vehicle body) and the unsprung weight (wheel) by Uneven road excitation and complicated road condition and to produce relative motion, thereby cause the piston rod mover 101 of semi-active suspension energy regenerative device and the linear relative movement between the stator 102, because piston rod mover 101 is permeability magnetic material, in the three-phase cake formula armature loop 1022 of stator 102, produce alternating current, the electric current that produces is by suitable processing, form with electric energy is stored in the vehicle power or super capacitor of motor vehicle driven by mixed power, and the steam supply car starts or accelerates.

Because the mutual action in the electric current that produces during the linear electric generator generating and the magnetic field of piston rod mover 101 can produce electromagnetic resistance; Like this, make the dumping force of semi-active suspension energy regenerative device be greater than the conventional hydraulic cylinder type damper, thereby connected a valve body 201 that has radial hole at piston rod mover 101, drive the motion of spool 202 by the dumping force control mechanism, spool 202 and the relative position of valve body 201 are changed, change the aperture of footpath throttling aperture, thereby change the flow passage area, reach the effect that changes dumping force; In car running process, suspension system ECU gathers the signal of sprung weight acceleration pick-up and unsprung weight acceleration pick-up, and the row operation of going forward side by side judges that the cartridge type linear electric generator can produce the size of electromagnetic resistance; ECU requires and suitable control algorithm according to Body Control then, send control signal and give controller, thereby change the size of the electric current that inputs to circular magnetic chuck electromagnet 301, to change the size that attracts connecting rod 303 power, the present patent application does not relate to the control system of energy regenerative device, does not do too much elaboration here; Because the upper end of connecting rod 303 is permeability magnetic material, under the effect of circular magnetic chuck electromagnet 301 suction, connecting rod 303 overcome limit spring 302 elastic force and along the axis upward movement, thereby drive spool 202 upward movements that are threaded with it, make spool 202 be in different positions, spool 202 changes the change that causes the radial hole orifice size with the relative position of valve body 201; According to the size of the required dumping force of vehicle operational mode, can change the working current of circular magnetic chuck electromagnet 301, so that the orifice size of radial hole can change according to working condition requirement; Like this, the aperture of fluid circulation path in piston assembly 404 between semi-active suspension energy regenerative device epicoele 406 and the cavity of resorption 407, also comprise the fluid path that radial hole on the valve body 201 and cored screw 204 endoporus are formed, thereby changed the size of dumping force, improved stability, traveling comfort and the safety of automotive operation.

When semi-active suspension energy regenerative device breaks down and can not reclaim the suspension vibrational energy, the received current of circular magnetic chuck electromagnet 301 then is cut off, connecting rod 303 is under the elastic force effect of limit spring 302, make the spool 202 that is threaded with it be against the end of cored screw 204, valve body 201 and spool 202 closures, namely the radial hole orifice size is zero on the valve body 201; At this moment, semi-active suspension energy regenerative device epicoele 406 only is the aperture in the piston assembly 404 with the circulation path of cavity of resorption 407 fluid, and semi-active suspension energy regenerative device is with traditional cylinder type hydraulic shock absorber form work.

By the effect of semi-active suspension energy regenerative device, a part of vibrational energy of suspension has obtained recovery, is stored in the power supply of motor vehicle driven by mixed power with the form of electric energy, for the secondary utilization of motor vehicle driven by mixed power; Simultaneously, because the dumping force of semi-active suspension can be according to the change of road traveling operating mode and adjusted, make ride comfort, stability and the safety of car load be greatly improved.
