Abstract
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...
Examples
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.
