Below in conjunction with accompanying drawing, specific implementation process of the present invention is described further.
To be encouraged by Uneven road and the road condition of complexity causes between sprung weight (vehicle body) and unsprung weight (wheel) and produces relative movement, thus cause the linear relative movement between the piston rod mover 101 of Semi-active suspension energy-regenerative device and stator 102, because piston rod mover 101 is permeability magnetic material, Ac is produced in the three-phase cake formula armature winding 1022 of stator 102, the electric current produced is by suitable process, in the vehicle power being stored into motor vehicle driven by mixed power with the form of electric energy or super capacitor, for automobile starting or acceleration.
Due to the interaction in the electric current of generation and the magnetic field of piston rod mover 101 when linear electric generator generates electricity, electromagnetic resistance can be produced.Like this, the damping force of Semi-active suspension energy-regenerative device is made to be greater than conventional hydraulic telescopic shock absorber, thus on piston rod mover 101, be connected to the valve body 201 that has radial hole, by the motion of damping force control mechanism band movable valve plug 202, spool 202 is changed with the relative position of valve body 201, change the aperture of radial hole, thus change liquid chunnel area, reach the effect changing damping force.In car running process, suspension system ECU gathers the signal of sprung weight acceleration transducer and unsprung weight acceleration transducer, and row operation of going forward side by side, judges that cartridge type linear electric generator can produce the size of electromagnetic resistance.Then ECU requires and suitable control algorithm according to Body Control, sends control signal to controller, thus changes the size inputing to the electric current of circular magnetic chuck electromagnet 301, to change the size attracting connecting rod 303 power.Upper end due to connecting rod 303 is permeability magnetic material, under the effect of circular magnetic chuck electromagnet 301 suction, connecting rod 303 overcomes the elastic force of limit spring 302 and moves upward along axis, thus drive the spool 202 be threaded with it to move upward, make spool 202 be in different positions, spool 202 changes with the relative position of valve body 201 change causing radial hole orifice size.The size of damping force needed for vehicle operational mode, can change the operating current of circular magnetic chuck electromagnet 301, can change to make the orifice size of radial hole according to working condition requirement.Like this, fluid circulation path between Semi-active suspension energy-regenerative device epicoele 406 and cavity of resorption 407 is except the aperture in piston assembly 404, also comprise the fluid path that radial hole on valve body 201 and cored screw 204 endoporus form, thus change the size of damping force, improve the stability of automobilism, travelling comfort and Security.
When Semi-active suspension energy-regenerative device breaks down and can not reclaim suspension vibration energy, the input current of circular magnetic chuck electromagnet 301 is then cut off, connecting rod 303 is under the elastic force effect of limit spring 302, the spool 202 be threaded with it is made to be against the end of cored screw 204, valve body 201 closes with spool 202, and namely on valve body 201, radial hole orifice size is zero.Now, Semi-active suspension energy-regenerative device epicoele 406 is only the aperture in piston assembly 404 with the circulation path of cavity of resorption 407 fluid, Semi-active suspension energy-regenerative device works with traditional Hydraulic shock absorber form.
By the effect of Semi-active suspension energy-regenerative device, a part of vibrational energy of suspension obtains recovery, is stored in the power supply of motor vehicle driven by mixed power with the form of electric energy, and the secondary for motor vehicle driven by mixed power utilizes.Meanwhile, because the damping force of semi-active suspension can be adjusted according to the change of road traveling operating mode, the smoothness of car load, stability and Security are greatly improved.
