Abstract
The utility model belongs to the field of electromobiles, in particular to a damping mechanism of an electromobile, which comprises a sleeve pipe. One end of the sleeve pipe is open, and the other end of the sleeve pipe is closed. A damping shaft is arranged in the sleeve pipe, a movable cavity is arranged in the damping shaft, the end portion of a movable post is arranged on a cavity opening of the movable cavity through a limit plate, the movable post protrudes out of the movable cavity through the cavity opening to be fixedly connected with a piston in the sleeve pipe, the piston and the closed end of the sleeve pipe form an air pressure space, an elastic part is formed between the piston and the movable post, protrusions with round edges are axially arranged on the damping shaft, a support guide face is arranged in the sleeve pipe, the damping shaft penetrates through the support guide face, and an elastic device is arranged between the protrusions with round edges and the support guide face. The damping mechanism has the advantages of being light and convenient to rotate, stable in damping, safe and simple and practical in structure.
Description
Technical field
The utility model belongs to electric automobiles, especially a kind of electric motor car damper mechanism.
Background technique
In the existing technology, the propons vibration damper of automobile mainly comprises sleeve pipe; Sleeve pipe is made up of the path section on top and the big footpath section of bottom, is inserted with telescopic pipe from big footpath Duan Yiduan in the sleeve pipe upper end closed, sleeve pipe; Telescopic pipe is inserted in the path section, the telescopic pipe upper end closed, and the telescopic pipe upper end is provided with elastic mechanism with the closed end of sleeve pipe; The closed end that long bolt passes closed end, elastic mechanism center and the sleeve pipe of telescopic pipe is connected telescopic pipe with sleeve pipe, be provided with the wear-resistant guiding lining between the internal surface of sleeve pipe of big footpath section and the telescopic pipe, and the telescopic pipe lower end is connected with wheel stationary axle and steering arm; Can spur telescopic pipe through steering arm and rotate, rotate, realize wheel steering thereby drive the wheel stationary axle; Side at sleeve pipe also is provided with the propons fixed plate; Can whole device be connected on the vehicle frame through the propons fixed plate, because the power-assisted of direction machine and hydraulic system is arranged, operator's direction of passage dish driving wheel easily turns to; Telescopic pipe pressure spring when running into vibrations is realized damping, avoids jolting.Its deficiency is: need the power-assisted of direction machine to accomplish during the work of this vibration damper and turn to; Steering wheel can not directly drive steering arm and realize equal angular turning to; Its reason is that the frictional force in the steering procedure is big; Make to turn to very difficulty that must could realize turning to smoothly by other mechanisms, the steering wheel rotation angle when turning to be much larger than the steering angle of wheel.
Summary of the invention
The purpose of the utility model is to the deficiency that exists in the above-mentioned technology, proposes a kind of electric motor car damper mechanism.
The technological scheme that realizes the utility model purpose is following:
The electric motor car damper mechanism, it comprises sleeve pipe, the sealing of sleeve pipe one end opening one end; Be provided with elastic axis in the sleeve pipe, be provided with a movable chamber in the elastic axis, the accent in movable chamber is located in the end of a movable post through limiting board; Movable post stretches out movable chamber from accent and is fixedly connected with a piston in the sleeve pipe, and the closed end formation air pressure space of piston and sleeve pipe is provided with elastic member between piston and the movable post; Be axially arranged with the round edge convexity on the elastic axis; Be provided with the support guide face in the sleeve pipe, elastic axis passes this support guide face, between round edge convexity and support guide face, is provided with elastic device.
Be provided with plane bearing between described elastic member and the limiting board.
Described elastic member and elastic device are cylindrical spring.
The utility model has the advantages that rotation is light, the stable and safety of damping, simple and practical.
