Abstract
Description
Technical Field
[0001] The utility model relates to a vehicle axle, in particular to an electric steering vehicle axle assembly consisting of a steering knuckle, a bridge housing and a brake. Background Art
[0002] At present, such a steering axle assembly is disclosed in the market, and its structural characteristics are as follows: it consists of a steering knuckle, a bridge housing and a brake, wherein one end of the steering knuckle is respectively provided at both ends of the bridge housing, and the brake is provided at the other end of the steering knuckle, and the steering knuckle is connected to the steering cylinder through a connecting rod mechanism. However, since the hydraulic drive has a certain hysteresis, its steering sensitivity is poor when it comes to a sharp turn, especially when it is used for vehicles operating in tunnels, it is easy to cause collision or rollover, and there is a great safety hazard. Summary of the invention
[0003] The utility model aims to provide an electric steering axle assembly which has good steering sensitivity and can improve driving safety.
[0004] To achieve the above-mentioned purpose, the utility model provides an electric steering axle assembly, which consists of a steering knuckle, a bridge housing and a brake. One end of the steering knuckle is respectively provided at both ends of the bridge housing, and the brake is provided at the other end of the steering knuckle. The steering knuckle is also connected to a driving gear installed on an electric motor through a passive gear, and the electric motor is provided on the bridge housing.
[0005] The electric motor is arranged on the bridge housing through a base.
[0006] The base is configured to be in a U shape.
[0007] The driven gear is arranged in a sector shape.
[0008] After adopting this structure, since the steering knuckle is also connected to the driving gear installed on the motor through the passive gear, and the motor is arranged on the bridge housing, the steering sensitivity is better and the driving safety can be improved.
