When Vehicle Driving Cycle, control unit 5 is only to the one input control signal in the first ratchet device and the second ratchet device.When control unit 5 is to the first electromagnet 21-1 and all not input service signals of the second electromagnet 21-2, the first ratchet 22-1 and the first ratchet 24-1 are in released state, the second ratchet 22-2 and the second ratchet 24-2 are also in released state, and now suspension can stretch or compress.
When vehicle is during at straight-line travelling emergency braking, control unit 5 is according to brake pedal position signal, vehicle body longitudinal acceleration signal judges when vehicle body may larger pitching occur, control unit 5 is to the second electromagnet 21-2 input control signal on the electromagnetism energy regenerative damping force generator 2 of vehicle rear suspension, second electromagnet 21-2 produce the suction-combining force overcome the second back-moving spring 19-2 pulling force make the second ratchet 22-2 around the second ratchet rotating shaft 20-2 dextrorotation then make the second ratchet 22-2 and the second ratchet 24-2 in bonding state, now energy regenerative rotor input shaft 23 only can rotate along clockwise direction, the rotation of energy regenerative rotor input shaft 23 drives ball-screw 14 in vertical, only can do downward straight-line motion with respect to ball nut 11.Because ball-screw in vertical 14 is in full accord with the change in location of spring carried mass 1, ball nut 11 is in full accord with the change in location of wheel mass 6, therefore above-mentionedly only can cause the suspension of vehicle only compressible by downward straight-line motion.Control unit 5 is to the first electromagnet 22-1 output services signal in the electromagnetism energy regenerative damping force generator 2 of vehicle front suspension simultaneously, the first electromagnet 22-1 generation the suction-combining force overcomes the first back-moving spring 19-1 pulling force makes the first ratchet 22-1 make the first ratchet 22-1 and the first ratchet 24-1 in bonding state around the first ratchet rotating shaft 20-1 left-hand revolution, now energy regenerative rotor input shaft 23 only can rotate in the counterclockwise direction, energy regenerative rotor input shaft 23 rotates and drives ball-screw 14 and ball nut 11 to interact, make ball-screw 14 in vertical, only can do straight-line motion upwards with respect to ball nut 11, cause the front suspension of vehicle only can stretch, thereby realize the pitching that reduces vehicle body, and then safety while improving vehicle straight-line travelling emergency braking.
In the time that control unit 5 judges that according to steering wheel angle signal and vehicle body lateral acceleration signal vehicle body larger side may occur inclines, the second electromagnet 21-2 input control signal inside control unit 5 travels to Vehicular turn in the electromagnetism energy regenerative damping force generator 2 of suspension, second electromagnet 21-2 produce the suction-combining force overcome the second back-moving spring 19-2 pulling force make the second ratchet 22-2 around the second ratchet rotating shaft 20-2 dextrorotation then make the second ratchet 22-2 and the second ratchet 24-2 in bonding state, now energy regenerative rotor input shaft 23 only can rotate along clockwise direction, anti-clockwise rotates and is limited, energy regenerative rotor input shaft 23 limit rotation are delivered to ball-screw 14, ball-screw 14 interacts with ball nut 11, cause Vehicular turn travel inner side suspension only compressible, the first electromagnet 22-1 input control signal outside while control unit 5 travels to Vehicular turn on the electromagnetism energy regenerative damping force generator 2 of suspension, the first electromagnet 22-1 generation the suction-combining force overcomes the first back-moving spring 19-1 pulling force makes the first ratchet 22-1 make the first ratchet 22-1 and the first ratchet 24-1 in bonding state around the first ratchet rotating shaft 20-1 left-hand revolution, now energy regenerative rotor input shaft 23 only can rotate in the counterclockwise direction, clockwise rotation is limited, the rotation of energy regenerative rotor input shaft 23 finally make Vehicular turn travel outside suspension only can stretch, thereby realize the inclination that reduces vehicle body, and then raising Vehicular turn driving safety.
When vehicle is in the time that Turning travel is braked, control unit 5 is according to steering wheel angle signal, brake pedal position signal, vehicle body lateral acceleration signal, vehicle body longitudinal acceleration judges when inclination and pitching may occur vehicle body simultaneously, inside control unit 5 travels to Vehicular turn there is the second electromagnet 21-2 input control signal on 2 in the electromagnetism energy regenerative dumping force of rear suspension, second electromagnet 21-2 produce the suction-combining force overcome the second back-moving spring 19-2 pulling force make the second ratchet 22-2 around the second ratchet rotating shaft 20-2 dextrorotation then make the second ratchet 22-2 and the second ratchet 24-2 in bonding state, now energy regenerative rotor input shaft 23 only can rotate along clockwise direction, anti-clockwise rotates and is limited, energy regenerative rotor input shaft 23 limit rotation are delivered to ball-screw 14, ball-screw 14 and ball nut 11 interact and these energy regenerative rotor input shaft 23 limit rotation are converted into ball-screw 14 in vertical only can do downward straight-line motion with respect to ball nut 11, therefore the above-mentioned Vehicular turn inner side rear suspension that travels that only can downward straight-line motion causes is only compressible, outside while control unit 5 travels to Vehicular turn there is the first electromagnet 22-1 input control signal in 2 in the electromagnetism energy regenerative dumping force of suspension and another front suspension, the first electromagnet 22-1 generation the suction-combining force overcomes the first back-moving spring 19-1 pulling force makes the first ratchet 22-1 make the first ratchet 22-1 and the first ratchet 24-1 in bonding state around the first ratchet rotating shaft 20-1 left-hand revolution, now energy regenerative rotor input shaft 23 only can rotate in the counterclockwise direction, clockwise rotation is limited, above-mentioned energy regenerative rotor input shaft 23 limit rotation are delivered to ball-screw 14, ball-screw 14 and ball nut 11 interact and these energy regenerative rotor input shaft 23 limit rotation are converted into ball-screw 14 in vertical only can do straight-line motion upwards with respect to ball nut 11, therefore above-mentioned travel outside suspension and another front suspension of Vehicular turn that only can straight-line motion upwards cause only can stretch, thereby realize the inclination and the pitching that reduce vehicle body simultaneously, and then reach the object of safety while improving Vehicular turn travelling brake.
