Automobile capable of adaptively adjusting shock absorbing effect

Abstract

The invention provides an automobile capable of adaptively adjusting a shock absorbing effect, and belongs to the technical field of automobiles. The automobile comprises a frame, four wheels and shock absorbers connected between the frame and the wheels correspondingly. Each shock absorber comprises a damping cylinder and a shock absorbing spring sleeving the damping cylinder, wherein the shock absorbing spring is a hollow spring with a damping hole inside, a plurality of first wires penetrate through the damping hole, the first wires are connected in parallel and then are connected with a second wire, the upper end of a liquid storage cavity is slidably connected with a pressure regulating piston, an armature block positioned above the pressure regulating piston is fixedly arranged on anupper mounting seat, the second wire is wound on the armature block in the same direction, and a first permanent magnet bar with the magnetic pole direction on the same straight line as the magneticpole direction of an electromagnetic structure formed by electrifying the second wire on the armature block is embedded in the pressure regulating piston; a permanent magnet group comprises a plurality of second permanent magnet strips which are circumferentially and uniformly distributed outside the axis of a cylinder body. The automobile has the advantages of being capable of adaptively adjusting the rigidity of the automobile shock absorbers and the like.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to an automobile capable of self-adaptively adjusting the damping effect. 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 wi...

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
