Abstract
The utility model discloses a middle shaft assembly used by a steering pipe column; a lining having the functions for resisting wear and reducing noise is added between the inner spline and the of the middle shaft assembly used by the existing steering pipe column and the outer spline of a cross axle of the middle shaft assembly used by the existing steering pipe column; consequently so that a novel structure of the indirect contact between the sliding lining of the inner spline and the transmission cross axle of the outer spline is formed. The novel transmission structure can not only effectively reduce transmission noise but also greatly extends the service life of the product.
Description
Technical field:
The utility model relates to parts-steering column countershaft assembly in the automobile steering system, belongs to The Design of Auto Parts, manufacturing technology field.
Background technology:
At present, the steering column countershaft assembly of the automobile steering system of domestic production generally can divide two kinds of forms: fixed type and sliding type.Fixed type: adopt single axle to connect two universal-joints up and down, this structure has two defectives: 1. owing to the employing single axle, and not flexible, safety is relatively poor, and 2. single axle easily produces vibration, shortens the service life of universal joint assembly.Sliding type: two universal-joints generally are connected with the male splines transmission shaft by the female splines sliding sleeve up and down, female splines sliding sleeve and male splines transmission shaft direct contact, this structure resistance to abrasion is relatively poor, generally need to the female splines sliding sleeve and the male splines transmission shaft is heat-treated or outside on the spline shaft coating nylon to improve its resistance to abrasion, do like this and must cause complex process, the increase cost of product.This structure also has another defective, because female splines sliding sleeve and male splines transmission shaft direct contact, when comparatively fierce vibrations take place in vehicle under complex road condition, easily form high-frequency vibration between female splines sliding sleeve and the male splines transmission shaft, produce noise, thereby influence the driver comfort of automobile, reduce the service life of product.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of simple in structure, and can reduce noise effectively, the steering column countershaft assembly that prolongs its service life.
For achieving the above object, the utility model has been taked following technical measures:
A kind of steering column countershaft assembly described in the utility model, be with between the female splines and center cross male splines of countershaft assembly at existing steering column, added one and had lining wear-resisting, decrease of noise functions, thereby constituted a kind of new structure by female splines slide bushing and the non-direct contact of male splines transmission center cross.
Not only can effectively reduce rotational noise through the utility model after the above-mentioned design, and prolong the service life of product greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that A-A of the present utility model is to structural representation
Wherein: 1-upper cardan fork 2-male splines transmission center cross 3-female splines sliding sleeve 4-sleeve pipe fork 5-lining
The specific embodiment:
A kind of steering column countershaft assembly described in the utility model includes upper cardan fork 1, male splines transmission center cross 2, and female splines sliding sleeve 3, parts such as sleeve pipe fork 4, upper cardan fork 1 connects firmly by welding with male splines transmission center cross 2; Sleeve pipe fork 4 and female splines sliding sleeve 3 connect firmly by welding; Between male splines transmission center cross 2 and female splines sliding sleeve 3, be equipped with a lining 5; Lining 5 adopts engineering plastics or nylon 6 material to make, and has very high wear-resisting, decrease of noise functions.
In fitting process, lining 5 adopts the riveted joint form with male splines transmission center cross 2, reinstalls female splines sliding sleeve 3, has avoided the direct contact of male splines transmission center cross 2 with female splines sliding sleeve 3.When automobile runs into complicated road strenuous vibration takes place, effectively absorbing high-frequency vibration of lining 5, the reduction noise, thus guaranteed the stationarity of universal-shaft drive effectively.
