Hydraulic and electromagnetic mixing device for automobile shock absorption

Abstract

The invention relates to the technical field of automobile shock absorbers, and discloses a hydraulic and electromagnetic mixing device for automobile shock absorption. The hydraulic and electromagnetic mixing device comprises a frame fixing ring, an arc permanent magnet is connected to the lower part of the frame fixing ring, a coil is connected to the outer side of the middle upper part of a hydraulic cylinder, and an annular permanent magnet is arranged in the hydraulic cylinder. The upper end of a support is connected with a metal ball, and the upper portion of the metal ball is connectedwith a variable resistor. The fixing ring drives a hydraulic rod to move downwards, the magnetic field intensity change of the permanent magnets moves relative to the coil, the coil generates current,and the coil generates the same magnetic field as the lower end of the arc permanent magnet, so that the frame fixing ring is prevented from moving downwards in the opposite direction. Hot air generated around the coil pushes the support to move, the metal ball on the support moves on the variable resistor, and therefore current in a variable resistor circuit is changed, and the structure solvesthe problems that an automobile shock absorber in the prior art is poor in shock absorption effect, and the shock absorption effect needs to be manually detected.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorbers, in particular to a hydraulic and electromagnetic hybrid device for automobile shock absorption. Background technique [0002] A car's shock absorber, also known as a suspension, is composed of a spring and a shock absorber. Its working principle is that when the frame and the axle are vibrated and there is relative motion, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity to the other through different pores. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the car is converted into the heat energy of the oil, which is then absorbed by the shock absorber and emitted into the atmosphere. The shock absorber is used to suppress After the spring absorbs the shock and reboun...
