Problems solved by technology

[0008] The problem to be solved by the present invention is that the meshing center distance of the worm gear and worm is not consistent with the center distance of the two cavities of the worm gear installation chamber and the worm installation chamber, resulting in meshing gaps, which will generate noise during the steering process and affect the comfort of the driver.

Abstract

Provided is an electric power steering system and a vehicle. The electric power steering system comprises a steering gear housing, a worm gear, and a worm. The steering gear housing is internally provided with a worm gear installation cavity and a worm installation cavity. The worm gear is installed in the worm gear installation cavity. The worm is installed in the worm installation cavity. The worm gear and the worm are meshed with each other. One axial end of the worm is provided with a first center distance adjusting mechanism, and the other axial end is provided with a second center distance adjusting mechanism. The first center distance adjusting mechanism and the second center distance adjusting mechanism can make the worm swing deviating the axis of the worm, so as to realize adjustment of the mesh center distance of the worm gear and the worm. Using the electric power steering system can realize mesh center distance of the worm gear and the worm, so that the mesh center distance of the worm gear and the worm is consistent with the center distance of the worm gear installation cavity and the worm installation cavity, and mesh interspace is not generated, so as to prevent to generate noise in a steering process.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an electric power steering system and an automobile. Background technique [0002] Electric Power Steering (EPS for short) is a power steering system that directly relies on the motor to provide auxiliary torque. EPS is mainly composed of torque sensor, vehicle speed sensor, electric motor, electric power steering, reduction mechanism and electronic control unit (ECU), etc. composition. Among them, the electric power steering housing is provided with a worm gear installation cavity and a worm screw installation cavity. The worm screw installation cavity is installed with a worm, and the worm gear installation cavity is installed with a worm gear. [0003] Due to the influence of factors such as machining error, assembly error and tooling environment, the center distance between the worm gear installation cavity and the worm screw installation cavity will change within a certain tolera...
