Problems solved by technology

Due to the gap in the axial direction of the telescopic motor, there is axial movement of the telescopic motor during operation, which will cause the worm gear and worm of the reduction mechanism to fail to mesh normally, resulting in excessive wear of the worm gear and worm, and unstable transmission, which will affect the height of the steering wheel Position adjustment, and at the same time, there will be obvious abnormal noise at the telescopic motor, which will affect driving comfort

Abstract

The invention discloses an axial adjusting device of an electric four-way adjustable steering column. The axial adjusting device of the electric four-way adjustable steering column includes a telescopic motor, a worm connected to the telescopic motor, a first limiting piece for applying a load to the worm, and a force transmitting piece positioned between the first limiting piece and the worm androtatable in the circumferential direction with the worm, and the force transmitting piece is in point contact with the first limiting piece and the worm. According to the axial adjusting device of the electric four-way adjustable steering column, the axial clearance of the telescopic motor is eliminated by arranging the force transmitting piece and the limiting piece, so that the axial movement of the telescopic motor and the worm does not occur in the running process, the failure of the height adjustment of the steering column caused by sticking of the motor is effectively avoided, the reliability is improved, and the comfort and safety of driving and riding are also improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle steering systems, in particular, the invention relates to an axial adjustment device for an electric four-way adjustable steering column. Background technique [0002] The steering system is a series of devices used to change or maintain the direction of driving or reversing of the vehicle. Among them, the steering column is used to connect the steering wheel and the steering gear, and is one of the important components of the steering system of the car. In the field of vehicle engineering, the steering column can adjust the position of the steering wheel up and down, forward and backward within a certain range to adapt to the driver's operating habits. [0003] When it is necessary to give the steering wheel to the driver or adjust the appropriate position of the steering wheel, the electric four-way adjustable steering column is adjusted by adjusting the switch. When adjusting the steering colu...
