Embodiment Construction

[0030] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0031] Such as Figure 1 to Figure 3 As shown, the present disclosure provides a rack and pinion set for a steering column, a steering column adjustment mechanism, and a vehicle. Wherein, the adjustment mechanism includes a pipe string clamping bracket 3 for clamping the pipe string assembly from the outside, and a connection for fixedly passing through the pipe string assembly and radially movable through the pipe string clamping bracket 3 The shaft 4, the column assembly includes a steering column 7 and a fixed bracket 8, the fixed bracket 8 is slidably connected to the connecting shaft 4 along the axial direction of the steering column 7, the connecting s...

Abstract

The invention relates to a rack gear set used for a steering tubular column, a steering tubular column adjusting mechanism and a vehicle. The rack gear set comprises a rack and a gear assembly engagedwith the rack, the rack is used for being fixed to a tubular column assembly, and the gear assembly is used for being rotatably mounted on a connecting shaft which penetrates through a tubular columnclamping bracket; and the rack extends in the axial direction of the tubular column assembly and is located on the outer side of the tubular column clamping bracket, and an elastic area making elastic contact with the tubular column clamping bracket is formed in one side of the gear assembly. Namely, axial adjusting noise of the tubular column assembly is reduced through continuous meshing of thegear assembly and the rack; the contact area is decreased by elastic contact of the elastic area and the tubular column clamping bracket, and radial adjusting noise of the tubular column assembly isreduced; and in addition, through meshing of a gear and the rack, the holding power of axial locking of the tubular column assembly is further increased when the tubular column assembly is locked, sothat the holding power of locking of the tubular column assembly is increased.

Description

technical field [0001] The present disclosure relates to the field of steering column adjustment of automobiles, in particular to a rack and pinion set for a steering column, a steering column adjustment mechanism and a vehicle. Background technique [0002] With the improvement of driver's requirements for driving comfort, many steering wheels have a four-way adjustment function, which is realized by the structure on the steering column. If the structural design is unreasonable, when the driver adjusts the steering wheel according to his own needs, adjustment noise will be generated, causing sensory discomfort to the driver; when the steering wheel is adjusted to a suitable position, the steering wheel adjustment handle is locked, and the steering wheel cannot maintain the original position due to external force. steering wheel adjustment position. Therefore, how to reduce the noise generated by adjusting the steering column while ensuring that the steering column still ha...
