Problems solved by technology

[0003] However, the existing oil shock absorber can only perform shock absorption passively, and cannot flexibly adjust the performance parameters of the shock absorber according to different working conditions in order to obtain a better shock absorption effect
In addition, when the vibration is frequent, the temperature of the oil will rise rapidly, which will not only reduce the viscosity of the oil, thereby affecting the shock absorption performance, but also easily cause leakage and cavitation

Embodiment 1

[0020] Such as figure 1 , 3 As shown, a shock absorber for automobiles includes a piston hydraulic shock absorber, the bottom of the piston hydraulic shock absorber cavity 1 communicates with the liquid inlet port of the Tesla turbine 2, and the piston hydraulic shock absorber cavity The upper part communicates with the outlet port of the Tesla turbine, the turbine shaft of the Tesla turbine is connected to the motor 5 at one end, and the fan blade 6 is arranged on the turbine shaft at the other end. Radiating fins 7 are provided on the Tesla turbine housing on the shaft end side of the fan blades.

[0021] The Tesla turbine has first and second liquid inlet ports, which are respectively used to drive the rotation of the impeller in two directions, and has first and second liquid outlet ports, the first liquid inlet port, the second liquid outlet port The liquid port communicates with the bottom of the piston hydraulic shock absorber cavity, the second liquid inlet port and ...

Embodiment 2

[0024] Such as figure 2 As shown, the difference from Embodiment 1 is that the piston hydraulic shock absorber is a rodless piston hydraulic cylinder, which includes a closed cylinder body, a ferromagnetic piston is arranged in the cylinder body, and the cylinder body is covered with a magnetic force that passes through the piston. The magnetic support frame of action, promptly is connected with the annular magnet 3 that frame body is enclosed within cylinder body. The closed cylinder body should be made of non-ferromagnetic material, and the magnetic support frame is equivalent to the piston rod, but it does not directly contact with the piston, but interacts through magnetic force.

Abstract

The invention provides an automobile damping device, belongs to the technical field of damping, and solves the problems that performances of a damper cannot be flexibly regulated and temperature of an oil liquid rises quickly during frequent vibration. The automobile damping device comprises a piston hydraulic damper, wherein the bottom of a cavity of the piston hydraulic damper communicates with a liquid inlet end opening of a Tesla turbine; the upper part of the cavity of the piton hydraulic damper communicates with a liquid outlet end opening of the Tesla turbine; one end of a turbine shaft of the Tesla turbine is connected to a motor; and fan blades are arranged on a turbine shaft at the other end. According to the automobile damping device provided by the invention, the damper is combined with the Tesla turbine, so that regulation on damping force of the damper can be realized through rotation of the motor; and the fan blades are arranged on the Tesla turbine, so that the oil liquid can be cooled by utilizing vibrating energy of the damper.

Description

technical field [0001] The invention belongs to the technical field of damping, and relates to a damping device for automobiles. Background technique [0002] In order to improve the ride comfort of the car, shock absorbers are installed in various parts of the car. For example, in order to damp vibration, the shock absorbers used in the car suspension system are mostly hydraulic shock absorbers. (or the body) and the axle are subject to relative motion due to vibration, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity through different pores into another cavity. At this time, the friction between the hole wall and the oil [1] and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the vehicle is converted into heat energy of the oil, which is then absorbed by the shock absorber and released into the atmosphere. When the oil passage...
