Abstract

The utility model provides a connecting structure of a steering shaft and a steering yoke. The steering shaft is connected with the steering yoke through a spline. One of spline teeth of the spline end of the steering yoke is missed and a blind tooth is formed in corresponding spline teeth of the spline end of the steering shaft; when the steering yoke is assembled with the steering shaft, the tooth-missed portion corresponds to the blind tooth so that the relative angle alpha between the steering yoke and the steering shaft can be kept. According to the scheme, the steering shaft and the steering yoke are provided with the blind tooth and the tooth-missed portion respectively, so that in the process of assembly, the prearranged tooth-missed portion and the prearranged blind tooth of the two connecting components are matched, and therefore the relative angle relation of the steering shaft and the steering yoke after the steering shaft and the steering yoke are connected is guaranteed.

Description

A kind of steering shaft and kingpin support draw bail

Technical field

The utility model relates to machinery manufacturing technology field, refers to especially a kind of steering shaft and kingpin support draw bail.

Background technology

The shortcomings such as existing steering shaft or kingpin support generally need to be realized by special tooling when assembling, exist time of setting up long, and angle control precision is poor, homogeneity of product is low.

Utility model content

The technical problems to be solved in the utility model is to provide steering shaft and the kingpin support draw bail that a kind of control accuracy is high, homogeneity of product is high, Product Assembly efficiency is high.

For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of steering shaft and kingpin support draw bail, described steering shaft and kingpin support pass through spline joint, in the spline tooth of described kingpin support splined end, be provided with a hypodontia, in the corresponding spline tooth of described steering shaft splined end, be provided with a blind tooth; When described kingpin support and steering shaft assembling, described hypodontia is corresponding with blind tooth to make described kingpin support and steering shaft keep relative angle α.

Wherein, described steering shaft is provided with plane on axle, establishes center cross mounting hole on described kingpin support, and on described axle, the line of centers of plane and described center cross mounting hole keeps relative angle α.

The beneficial effect of technique scheme of the present utility model is as follows:

In such scheme, by design respectively blind tooth and hypodontia on steering shaft and kingpin support, during assembling, hypodontia and blind tooth that two coupling components design in advance match, to guarantee the relative angle relation after steering shaft and kingpin support connect.

The specific embodiment

For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.

The problems such as the utility model is long for the time of setting up of existing steering shaft and the existence of kingpin support draw bail, angle control precision is poor, homogeneity of product is low, provide a kind of steering shaft and kingpin support draw bail.

As shown in Figure 1, Figure 2 and Figure 3, embodiment of the present utility model provides a kind of steering shaft and kingpin support draw bail, described kingpin support 1 and steering shaft 2 pass through spline joint, in the spline tooth 12 of described kingpin support 1 splined end, be provided with a hypodontia 13, in the corresponding spline tooth 22 of described steering shaft 2 splined end, be provided with a blind tooth 23; When described kingpin support 1 assembles with steering shaft 2, described hypodontia 13 and the corresponding cooperation of blind tooth 23, to make described kingpin support 1 can keep relative angle α with steering shaft 2.

Wherein, on described kingpin support 1, establish center cross mounting hole 11, described steering shaft 2 is provided with plane 21 on axle, and on described axle, plane 21 keeps relative angle α with the line of centers of described center cross mounting hole 11.

In such scheme, by design respectively blind tooth 23 and hypodontia 13 on steering shaft 2 and kingpin support 1, during assembling, hypodontia 13 and blind tooth 23 that two coupling components design in advance match, to guarantee the relative angle relation after steering shaft 2 and kingpin support 1 connect; Thereby improved efficiency of assembling, guaranteed angle control precision, product is unanimously high.

The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
