Self-adaptive automobile shock absorber realizing stepless adjustment

Abstract

The invention provides a self-adaptive automobile shock absorber realizing stepless adjustment, and belongs to the technical field of automobiles. The self-adaptive automobile shock absorber comprisesa damping cylinder and a damping spring which is arranged outside the damping cylinder in a sleeving mode; the damping spring is a hollow spring internally provided with a damping hole; a plurality of first wires penetrate through the damping hole; the first wires are connected in parallel and then connected with a second wire; the upper end of a liquid storage chamber is slidably connected witha pressure adjusting piston; an armature block located above the pressure adjusting piston is fixedly arranged on an upper mounting base; the second wire is wound on the armature block in the same direction; a first permanent magnet strip of which the magnetic pole direction is in the same straight line as the magnetic pole direction of an electromagnetic structure formed after the second wire onthe armature block is powered on is embedded in the pressure adjusting piston; a permanent magnet group comprises a plurality of second permanent magnet strips which are uniformly distributed in the circumferential direction and outside the axis of a cylinder body; the second wire is connected with a resistor in series; and the second wire is provided with a slide rheostat connected with the resistor and the second wire which is wound on the armature block in parallel. The self-adaptive automobile shock absorber provided by the invention has the advantages of manually intervening the rigidityof the automobile shock absorber and the like.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a stepless adjustable adaptive automobile shock absorber. Background technique [0002] The damping effect of the suspension / shock absorber of automobiles (including other vehicles) is generally formatted, that is to say, the damping effect after manufacture and installation cannot be actively adjusted, but in fact, for different driving Road conditions, the requirements for the damping effect in the ideal state are different. For example, when passing a raised obstacle on the ground such as a speed bump, the most ideal state is: at the initial stage of contacting the obstacle, the wheels are quickly approached relative to the body to compensate for the raised surface on the ground. The longitudinal elevation of the vehicle body caused by the sudden upward movement of the wheels, after crossing the highest point of the raised obstacle, it is hoped that the wheels will move away ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the damping size is adjusted by passively controlling the hydraulic pressure of the hydraulic cylinder used for guidance and resistance, thereby changing the vibration damping mode of the vehicle, but this method either cannot actively make adaptive adjustments according to road conditions, or requires complicated monitoring and control system with complex structure and high cost

[0004] Existing shock absorbers still have heat dissipation problems that affect the actual resistance effect and the service life of the damping cylinder, such as the high temperature of the damping cylinder

[0005] Due to the harsh environment of the suspension system of the vehicle, the low ground clearance, and frequent physical damage caused by wading and mudstones, the reliability and safety of installing and installing electronic devices on various parts of the suspension are low. It is conducive to the layout of components, which is one of the reasons why the suspension system is difficult to achieve intelligent control
