Embodiment Construction

[0016] exist figure 1 Among them, the outer ring of the oil storage barrel 8 is welded with a bracket cylinder 18 for supporting the permanent magnet frame 3 . The permanent magnet frame 3 is an annular structure, as shown in figure (2), there are 6 permanent magnets 21 evenly distributed inside, and the permanent magnet frame is a non-sealed structure, so a magnetic field can be generated inside. (See image 3 )

[0017] The shock absorber piston rod 6 is partly designed as a screw structure 22 . Utilizing the principle of the ball screw, the up and down vibration of the piston rod is converted into the rotational motion of the screw nut 20 . The coil 4 surrounding the outer ring of the lead screw nut 20 rotates together with the lead screw nut 20, thereby cutting the magnetic field lines in the magnetic field generated inside the permanent magnet frame 3. As can be known from Faraday's law of electromagnetic induction, The generated current is alternating current, which ...

Abstract

The invention discloses an energy feedback suspension device having a vibration energy recovery function, and belongs to the technical field of vehicle energy saving and emission reduction. On the basis of a traditional dual-cylinder bidirectional damper, a vibration energy recovery device is additionally arranged between an oil storage barrel and a dustproof cover. A magnet frame is connected in a welding manner onto a bracket cylinder connected in a welding manner onto the oil storage barrel, and permanent magnets are uniformly distributed on the magnet frame to generate a magnetic field. The part, located on the device, of a piston rod of the damper is designed as a screw rod structure, and a coil is wound on the excircle of a leadscrew nut. The energy feedback suspension device having the vibration energy recovery function is beneficial for improving the performance of a passive suspension system and the handling stability and driving smoothness of a vehicle.

Description

technical field [0001] The invention relates to an energy-feeding suspension device with vibration energy recovery, which belongs to the technical field of automobile energy saving and emission reduction. Background technique [0002] Suspension is the general term for all force transmission connection devices between the frame and the axle. According to whether the stiffness and damping of the suspension system are variable, it can be divided into active suspension and passive suspension. The use of active suspension is limited due to problems such as excessive energy consumption. Passive suspension is still more commonly used in cars now. Since the spring stiffness and the damping coefficient of the shock absorber are not adjustable and cannot be changed with the external road conditions, the design can only ensure good damping performance under certain driving conditions, and it is difficult to adapt to different road conditions. limited. [0003] With the increasingl...
