An energy-feeding type vibration isolation device

Abstract

The invention belongs to an energy feeding type vibration isolating device in the field of energy conservation and emission reduction of automobiles. The device comprises a cylinder barrel, a ball screw type piston rod, a main bevel gear, auxiliary bevel gears and an energy storing device. Grooves where an electromagnetic coil is wound are evenly distributed in the ball screw type piston rod in the axial direction. The electromagnetic coil is electrically connected with the input end of the energy storing device. Permanent magnets and iron cores are alternately arranged on the inner wall of the cylinder barrel by a circle in the axial direction. The main bevel gear is meshed with a ball screw structure through internal threads. The two sides of the main bevel gear are meshed with the auxiliary bevel gears respectively through external threads. Vertical movement of a suspension frame is converted into rotating movement through the ball screw structure, and therefore the purpose of isolating automobile vibration through movement state conversion is achieved. When the permanent magnets and the closed electromagnetic coil relatively move, an electromagnetic coil winding will generate induced current so that induced electromotive force can be generated, vibration energy is recycled so that energy conservation of an automobile can be achieved, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of automobile energy saving and emission reduction, and specifically relates to an energy-feeding type vibration isolation device. Background technique [0002] The vibration isolation device is a kind of shock absorber that installs machinery or instruments on suitable elastic devices to isolate vibration. Shock absorber is a crucial part of the car suspension, and its performance directly affects the ride comfort and handling stability of the car. At present, we usually use the traditional double cylinder hydraulic shock absorber on the passive suspension, such as the hydraulic shock absorber disclosed in patent CN93202010.0, the variable damping shock absorber disclosed in CN201020616405.5, etc. When the liquid repeatedly flows from one cavity to another, the friction between the liquid molecules and the hole wall forms a vibration damping force, but this kind of shock absorber dissipates the vibration energy of t...

At present, we usually use the traditional double cylinder hydraulic shock absorber on the passive suspension, such as the hydraulic shock absorber disclosed in patent CN93202010.0, the variable damping shock absorber disclosed in CN201020616405.5, etc. When the liquid repeatedly flows from one cavity to another, the friction between the liquid molecules and the hole wall forms a vibration damping force, but this kind of shock absorber dissipates the vibration energy of the suspension in the form of heat energy, which indirectly increases reduce the fuel consumption of vehicles, which does not meet the theme of energy saving and emission reduction in today's society
