Description
Technical Field
The invention belongs to the field of automobile energy-saving technology and novel suspensions, and mainly relates to an automobile suspension vibration energy recovery system.
Background
The suspension is a general name of all connecting devices between a frame and an axle (or wheels) of an automobile, and the common suspension of the existing automobile has the characteristics that the spring stiffness and the damping coefficient of a shock absorber are not adjustable, can not be automatically adjusted along with the road condition, and only has good adaptability to the road input under the specific road condition. The traditional automobile suspension has limited damping effect, most vibration energy is consumed in the form of heat energy, and in the aspects of light weight, energy conservation and emission reduction of the automobile, the lorry can continuously vibrate in the transportation process, so that the collection of energy generated by the vibration of the automobile is considerable. At present, energy feedback suspensions are mainly classified into electromagnetic type, kinetic energy type and hydraulic type according to energy conversion types, and the three types of energy feedback mechanisms are relatively complex, low in energy recovery efficiency, poor in energy input stability and the like, so that the energy feedback suspensions are not widely applied to the automobile market.
For example, in the prior invention patent "a piezoelectric energy recovery device applied to an automobile suspension system" (CN109728747A), a ball screw and a screw nut component are adopted to convert linear motion between an automobile body and a wheel into rotary motion, a piezoelectric material with high energy density is adopted, a piezoelectric sheet is deformed by magnetic force, and vibration energy loss caused by friction is reduced. The invention discloses an automobile suspension energy recovery device (CN201712474U), which adopts a structure provided with a ball screw and a screw nut working cylinder, and provides the automobile suspension energy recovery device without reversing a motor rotor so as to protect a motor and prolong the service life of the motor. Both of the two patents adopt the ball screw mechanism, and the requirement on the piezoelectric material in the first patent is high, so the problems of production cost, manufacturing and mounting precision requirement, lubrication and maintenance and the like of the two patent devices limit the practical engineering application of the two patent devices.
The invention discloses a parallel energy-feedback suspension system with a few-degree-of-freedom (CN105667238A), which adopts a parallel mechanism with few-degree-of-freedom, so that a rotary moving platform is connected with an over-motion pair and a piezoelectric disc of a rotary ultrasonic motor, and a friction disc of the ultrasonic motor is fixed on the inter-shaft quality, thereby improving the energy conversion efficiency. But the rotary platform is connected with the piezoelectric disc in a friction mode, the piezoelectric disc deforms under the action of friction force, unnecessary heat energy is generated, and the conversion efficiency of the energy is influenced. In addition, the cost problem of the ultrasonic motor proposed by the patent is difficult to solve.

The multi-rod parallel suspension consists of a driving disk (1), a driven disk (2), six push-pull rods (3), a return spring (4), a main universal joint bearing (5) and a secondary universal joint bearing (6), wherein the driving disk (1) and the main universal joint bearing (5) are fixedly connected but keep the relative rotation of the main universal joint bearing (5); the driven disc (2) is fixedly connected with the driven universal joint bearing (6) and does not rotate relatively to the driven disc (2), so that the driven universal joint bearing (6) can transmit torque to the driven disc (2) under the action of the push-pull rod (3), and the driven disc (2) can keep the rotating capacity when the driving disc (1) moves vertically; the driven disc (2) is fixedly connected with the main synchronous belt wheel (7); the primary synchronous pulley (7) and the secondary synchronous pulley (8) are respectively connected with the synchronous belt (9) through a tooth; the auxiliary synchronous belt wheel (8) is fixedly connected with an alternating current motor (10);
when the multi-rod parallel suspension moves, the driving disc (1) moves up and down in the vertical direction under the pressure action of the frame, so that the spatial distance between the driving disc (1) and the driven disc (2) changes, the push-pull rod (3), the main universal joint bearing (5) and the auxiliary universal joint bearing (6) move relatively in the space, the driven disc (2) rotates forwards or backwards periodically in the horizontal plane, the main synchronous belt wheel (7), the auxiliary synchronous belt wheel (8) and the alternating current motor (10) rotate, and the conversion from mechanical energy generated by the vibration of the multi-rod parallel suspension to electric energy is realized. The multi-rod parallel suspension is reset under the action of the reset spring (4), and the next motion cycle is ensured. The tension pulley (11) can keep the tightness of the meshing of the synchronous belt (9) with the primary synchronous pulley (7) and the secondary synchronous pulley (8) so that the synchronous belt does not loosen under the vibration of the vehicle. The recovered electric energy can be used for vehicle electric equipment or for driving an electric vehicle. When the vibration is not sufficient to compress or stretch the suspension return spring (4), no electric power is generated. The change of the electric energy is related to the deformation of the suspension due to the motion.
