Abstract
The utility model relates to a damping mechanism, in particular to a damping mechanism of a steering column of an automobile. The damping mechanism of the steering column of the automobile comprises a pipe fork, a connecting sleeve pipe, a bushing and a spline shaft. The connecting sleeve pipe is arranged inside the bushing, the pipe fork is sleeved outside the bushing, the spline shaft is inserted into the sleeve pipe in a connecting mode, and a cross hole is arranged in the pipe fork. The damping mechanism of the steering column of the automobile is compact in structure, and convenient and simple to assemble, and improves working efficiency and reduces product waste rate.
Description
Technical field
The utility model is a kind of damping, particularly a kind of damping of car steering tube column.
Background technology
Shock absorption device of the prior art directly with lining and sleeve fork force together, usually needs to process the lower end of steering shaft with steering shaft when the processing steering shaft, come to cooperate with lining and sleeve fork, often so that the difficulty of processing of steering shaft is large, operation increases, and reject rate is high.
Chinese patent 201120406959.7, a kind of steering column is disclosed, be particularly related to a kind of car steering column, this steering column comprise steering column, with the fixing lower steering column of the lower end interference fit of described upper steering column, the outside, upper end of described lower steering column is fixed with head bearing, and the outside, lower end of this time steering column is fixed with lower bearing.Described upper steering column is solid axle, and this time steering column is hollow tubular.There is above-mentioned shortcoming in this structure relative complex.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and compact conformation is easy for installation, increases the conformability of production, the damping of the car steering tube column of enhancing productivity simultaneously.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of damping of car steering tube column, comprise sleeve fork, connector bushing, lining and castellated shaft, described connector bushing is located in the lining, and described lining overcoat has sleeve fork, described castellated shaft is plugged in the connector bushing, is provided with cross bore in the described sleeve fork.
As preferably, be provided with axis hole in the described lining, the head of described axis hole is provided with the indent back-up ring, and the afterbody of described lining is provided with it mutually integrated mounting ring, and described mounting ring keeps off mutually with connector bushing and connecing.
As preferably, the afterbody of described axis hole is provided with fitting recess, and the cross-sectional plane of described fitting recess is echelon form, and the two side ends of described mounting ring is respectively equipped with bevel.
As preferably, described connector bushing comprises inner sleeve, and described inner sleeve is provided with overcoat outward, and described overcoat and interior inner room are provided with rubber coating.
As preferably, the interior knuckle of described inner sleeve, the outer knuckle of overcoat are respectively the inclined-plane, and the angle of inclination on described inclined-plane is 15 degree, and the inwall of described inner sleeve is the annular knurl face.
As preferably, the line of centers of described cross bore parallels distribution with the line of centers of castellated shaft.
Therefore, the damping of the car steering tube column that the utility model provides, compact conformation assembles easyly, increases work efficiency, and reduces product rejection rate.
