Abstract

The invention discloses a spring and air bag type damper of an electric vehicle. The spring and air bag type damper of the electric vehicle comprises a damper body, a piston, an inner rod, an outer spring, an upper fulcrum, a lower fulcrum and a high-pressure air bag. The outer spring is arranged outside the damper body in a sleeving mode. The piston is arranged in an inner cavity of the damper body, so that an upper piston cavity is formed. The piston is connected with one end of the inner rod. The other end of the inner rod stretches out from the tail of the damper body and is provided with the lower fulcrum. The upper fulcrum is arranged at the top of the damper body. The high-pressure air bag communicates with the upper piston cavity. According to the damper, damping in all directions can be provided, operation is stable, and the vibration absorption and reduction effect is good.

Description

technical field [0001] The invention belongs to the technical field of dampers, in particular to a spring damper for an electric vehicle. Background technique [0002] Various frictions and other obstructions that attenuate free vibration are called damping. Special components placed on the structural system can provide resistance to movement and devices that consume movement energy are called dampers. [0003] The damper is usually installed between the front wheel and the front fork, the rear wheel and the seat tube of the electric vehicle to play the role of buffering and vibration reduction. There are many types of dampers currently on the market, including hydraulic dampers, pneumatic dampers, spring dampers, electromagnetic dampers, pulse dampers, and rotary dampers. The hydraulic damper mainly uses the resistance generated when the hydraulic oil flows through the blocking hole to achieve the purpose of vibration absorption, while the air damper is a vibration damping...
