Problems solved by technology
[0005] Due to errors in the machining dimensions of the first steering shaft, lower pipe column assembly, upper pipe column assembly, and telescopic pipe assembly, there is an axial gap in the height adjustment process of the first steering shaft, which will cause the steering wheel to move up and down. The phenomenon of swaying will affect the driver's sense of control and driving comfort, and in severe cases will affect the safety of driving

The invention discloses an axial gap adjustment device for an electric four-way adjustable steering column. The electric four-way adjustable steering column includes an upper column assembly, a lower column assembly, a first steering shaft, and a second steering shaft and the third steering shaft, the first steering shaft is installed on the upper pipe column assembly through the first bearing and the second bearing, and the axial clearance adjustment device includes an axial anti-backlash mechanism that applies load to the first bearing and a shaft circlip that is sleeved on the first steering shaft and cooperates with the second bearing to axially limit the first steering shaft. The axial anti-backlash mechanism and the second bearing are located on the first bearing between the shaft and the circlip. The axial gap adjustment device of the electric four-way adjustable steering column of the present invention can eliminate the axial gap between the first steering shaft and the upper column assembly, thereby avoiding the problem of the steering wheel moving up and down, and improving the electric The reliability of the four-way adjustable steering column also improves the comfort and safety of driving.
Description
technical field [0001] The invention belongs to the technical field of vehicle steering systems, and in particular relates to an axial clearance adjusting device for an electric four-way adjustable steering column. Background technique [0002] Steering system is a series of devices used to change or maintain the driving or reverse direction of a 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 automobile steering system. 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 suit the driver's operating habits. [0003] When the steering wheel needs to be given way to the driver or the appropriate position of the steering wheel needs to be adjusted, the electric four-way adjustable steering column is adjusted through the adjustment switch. When the steering column is adj...
