Abstract

Disclosed is a four-wheel electric car. The utility model relates to a vehicle. The electric car is provided with two front wheels. The two front wheels are connected with a car frame through a centre connecting shaft of the front wheels. A steering mechanism comprises a trifurcate shaft, a steering shaft and steering linkage rod. The steering shaft is connected with the steering linkage rod through a U-shaped connecting part. The steering linkage rod is connected with the trifurcate shaft through the U-shaped connecting part, and the trifurcate shaft is connected with the centre connecting shaft of the front wheels. The two ends of the centre connecting shaft of the front wheels are respectively provided with a damping device. The steering mechanism drives the connecting shaft of the front wheels to change direction, and therefore the operation is very flexible. The four-wheel electric car has the advantages of being simple in structure and good in practicality.

Description

Four-wheel electric motor car
Technical field
The utility model relates to a kind of vehicle, is specifically related to a kind of four-wheel electric motor car.
