Vibration reduction device subjected to strong intervention

Abstract

The invention provides a vibration reduction device subjected to strong intervention, and belongs to the technical field of automobiles. The vibration reduction device subjected to strong interventioncomprises a damping cylinder and a vibration reduction spring. The vibration reduction spring sleeves the damping cylinder. The vibration reduction spring is a hollow spring, and a damping hole is formed inside the vibration reduction spring. Multiple first wires are arranged in the damping hole in a passing mode, and the first wires are connected in parallel and then connected with a second wire. A pressure adjusting piston is connected with the upper end of a liquid storage cavity in a sliding mode. An armature block which is located above the pressure adjusting piston is fixedly arranged on an upper installation base, and the second wire is wound around the armature block in the same direction. A first permanent magnet strip is embedded into the pressure adjusting piston, and the magnetic pole direction of the first permanent magnet strip and the magnetic pole direction of an electromagnetic structure which is formed after the second wire on the armature block is energized are located on the same straight line. A permanent magnet set comprises multiple second permanent magnet strips which are uniformly distributed outside the axis of a cylinder body in the circumferential direction. The damping hole and the liquid storage cavity communicate with each other through a liquid outlet channel, and the pressure adjusting piston partially covers the liquid outlet channel when thevibration reduction spring is located in the initial state. The vibration reduction device subjected to strong intervention has the advantage that the rigidity of the vibration reduction device can beadjusted in a self-adaptation and high-strength mode.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a strong intervention damping device. 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 from the vehicle bo...

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
