Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of vibration energy regeneration suspension, comprising: bolt 1, gear case 2, upper bracket of the spring 3, damper spring 4, rubber jacket 5, ball-screw 6, feed screw nut 7, spring lower support 8, damping rubber block 9, installation suspension ring 10, mount pad 11, motor mounting flange 12, motor 13 and epitrochoidal chamber 14.Wherein, the structure of gear case 2 as shown in Figure 2, mainly comprises: end cap 2-1, the first gear driving pair 2-2, gear case outer wall 2-3, angular contact ball bearing 2-4, the first transmission shaft 2-5, second driving shaft 2-6, antifriction-bearing box 2-7, the second gear driving pair 2-8 and the 3rd transmission shaft 2-9.
Gear case 2 is fixed on below mount pad 11, and bottom mount pad 11, be respectively equipped with upper bracket of the spring 3 and motor mounting flange 12, motor mounting flange 12 is connected with motor 13, and motor 13 carrys out vehicles chassis height for generating and Driving Torque.Be provided with ball-screw 6 below described upper bracket of the spring 3, outside ball-screw 6, be provided with damper spring 4, for electronlmobil suspension system vibration damping and make suspension return to initial position.Being provided with rubber sleeve 5 outside damping spring 4, entering for preventing the foreign objects such as dust, the grains of sand.Be connected on spring lower support 8 by feed screw nut 7 bottom ball-screw 6; Below spring lower support 8, be provided with epitrochoidal chamber 14, epitrochoidal chamber 14 is for providing the space of upper and lower perpendicular movement during suspension vibration, its chamber outer wall is used for preventing entering of the impurity such as extraneous stone, the grains of sand.Epitrochoidal chamber 14 is fixed on spring lower support 8 by bolt 1; Be provided with damping rubber block 9 in epitrochoidal chamber 14 inside with ball-screw 6 lower end, damping rubber block 9 shields, for preventing ball-screw end impaired.Be provided with bottom epitrochoidal chamber 14 and suspension ring 10 are installed, suspension ring 10 are installed and are fixedly mounted under vehicle suspension on brachium pontis by articulated manner.
Gear case 2 inside is double reduction gear driving device, and the first transmission shaft 2-5 is connected with ball-screw 6, and the 3rd transmission shaft 2-9 is connected with motor 13.As the Poewr transmission mechanism between ball-screw 6 and motor 13, the inner first transmission shaft 2-5 of gear case 2 installs the gear z2 that gear z1 and second driving shaft 2-6 installs and form the first gear driving pair 2-2.Wherein, gear number of teeth z1>z2, the two meets the condition of gear correct engagement.Second driving shaft 2-5 is coaxially installed with gear z3, the gear z4 that z3 and the 3rd transmission shaft 2-9 installs engages formation second pinion rotation secondary 2-8.Wherein, gear number of teeth z3>z4, the two meets the condition of gear correct engagement.First transmission shaft 2-5 connects one end of ball-screw 6 and is arranged on gear case 2 by angular contact ball bearing 2-4, and angular contact ball bearing 2-4 to move the axial force be subject to for offsetting ball-screw 6.The first transmission shaft 2-5 other end and second driving shaft 2-6, the 3rd transmission shaft 2-9 are arranged on gear case 2 by antifriction-bearing box.Because the number of teeth of gear case 2 internal gear transmission has z1>z2, z3>z4, the low rotation speed large torque motion of ball-screw 6 one end so can be converted into from the little torque motion of high rotating speed of motor 13 mouth, thus improve the efficiency of energy regenerating, also facilitate the adjustment of ACTIVE CONTROL to suspension and electric automobile chassis height.
Vibration energy regeneration process described in the utility model is: electronlmobil is in the process travelled, and the relative rectilinear vibration of suspension part vehicle body and vehicle bridge is converted into the rotary motion of ball-screw 6 by ball screw assembly.By transmission of power and the speedup of gear case 2, drive motor 13 rotates.According to electromagnetic induction principle, electric machine rotation will produce induced electric motive force, the electric energy of generation first through the rectification of motor-drive circuit, then through the filtering of energy recovering circuit, boost chopper effect, the direct current (DC) of stable output, thus charge to battery pack.The gear drive of gear case 2 inside, through the transmission of power of the first gear driving pair 2-2 and the second gear driving pair 2-8 and accelerating function, can improve the rotating speed of motor 13, thus improve the efficiency of vibration energy regeneration.
The utility model can not only reclaim energy, can also carry out ACTIVE CONTROL to suspension.
Electronlmobil is in the process travelled, and motor 13 rotates generating, produces the electromagnetic torque contrary with velocity of rotation direction simultaneously.Suspension control system by the control to battery charge, can regulate the electromagnetic torque size of motor 13, realizes the active control function of suspension.The electromagnetic torque of motor 13 is by the transmission of power of gear case 2, and be applied on ball-screw 6, by the conversion of motion of ball screw assembly, suspension system will be subject to the axial force of ball screw assembly, the active controlling force that can regulate of Here it is suspension.The gear drive of gear case 2 inside is through the transmission of power of the second gear driving pair 2-8 and the first gear driving pair 2-2, moment of torsion can be increased while reduction motor rotation speed, the more convenient axial force to ball-screw regulates, and is easy to the active control function realizing suspension.
Suspension control system, according to whether carrying out active adjustment to the electromagnetic torque of motor 13, is divided into Active control suspension and passive suspension.The implementation procedure of Active control suspension is: suspension control system microcontroller acquires suspension vibration speed sensor signal and cell pressure, electric current, temperature signal, can control energy recovering circuit, realize the control to battery charge, thus the control realized motor 13 electromagnetic torque, reach the object of the axial force size that control suspension is initiatively subject to, complete active suspension function.If control system does not carry out active adjustment to the electromagnetic torque of motor 13, but based on energy regenerating, then the transmission of power exported via motor 13 is uncontrolled to the axial force of ball-screw 6 end, and so suspension system is in passive suspension state.
The utility model also controls chassis height by ball screw assembly.When electronlmobil is by the poor uneven road surface of road conditions, the Oscillation Amplitude of suspension is also not obvious, and vehicle is less demanding to travelling comfort, and higher by performance requriements to electronlmobil.When electronlmobil travels at expressway surface, need to reduce vehicle chassis height, increase vehicle stability, reduce to travel windage simultaneously.So, what suspension system needs were in good time carries out active adjustment to chassis height.
Now, suspension does not carry out energy regenerating, but by battery discharge, suspension control system Microprocessor S3C44B0X motor-drive circuit, makes motor 13 be in motor-operated running state, Driving Torque.By the transmission of power of gear case 2, be applied on ball screw assembly, the axial linear movement of generation makes the height of vehicle body and vehicle bridge raise or reduce, and realizes the adjustment to electric automobile chassis height.Same, the gear drive of gear case 2 inside is through the transmission of power of the second gear driving pair 2-8 and the first gear driving pair 2-2, the moment of torsion of motor output end can be increased while reducing motor rotation speed, the more convenient axial force to ball-screw regulates, and is easy to the regulatory function realizing chassis height.Suspension control system microprocessor, by gathering the tach signal of photoelectric vehicle height sensor signal and motor 13, realizes the accurate adjustment to chassis height.
The utility model can reclaim energy during electronlmobil suspension vibration, extends electronlmobil continual mileage; And the active that can realize suspension and Passive Control, improve ride comfort and safety; Meanwhile, timely adjustment can be carried out to electric automobile chassis height, increase vehicle carrying capacity or reduce windage.
