Abstract
The utility model relates to a steering post tube which is benefit for the choosing of standard bearings and the adoption of the clock spring with a big diameter. Wherein, a steering mandrel is supported and fixed by a steering bearing; the head of the steering post tube is a variable shape namely the diameter of the two ends are big and the diameter of the tube body is small; the steering bearing is fixed and arranged by means of an auxiliary bush, and therefore the standard springs with a small size can be chosen and the tube ends with a bigger size can be obtained, so a combination switch can be arranged conveniently so as to meet the needs for using the clock springs with a bigger diameter.
Description
Technical field
The utility model relates to automotive steering structure, specifically is exactly steering-column tube.
Background technology
Turning to column jecket in the prior art is an isometrical body, turn to mandrel to fix by the steering bearing that is set directly in the steering-column tube, steering-column tube for less caliber size, selection and assembling there is no too many difficulty, and just must adopt the purpose made bearing to cooperate with it for the bigger column jecket of caliber size, and lost the possibility of using standard rolling bearing, give and produce and manage and bring a new difficult problem.
The person in charge of the prior art mostly is through-type, manufacturing process is comparatively simple, but it need use clock spring (or loudspeaker contact) to be fixed on the combined switch, and then combined switch linked together by column jecket on bolt or draw-in groove and the Steering gear, so give make, assembling and maintenance bring a lot of inconvenience, and the dimension limit of assembly inner body and workmanship also have influence on the performance of miscellaneous part easily.
Summary of the invention
The purpose of this utility model provides a kind of steering-column tube that helps selection standard spare bearing and be convenient to adopt big caliber clock spring.
For achieving the above object, the technical solution adopted in the utility model is: a kind of steering-column tube, turn to mandrel by the steering bearing support fixation, it is characterized in that: the tube head place of steering-column tube is the reducing shape that end diameter is big, the pipe shaft diameter is little, the outer wall of described steering bearing cooperates with a sleeve pipe, and described sleeve pipe is positioned at the tube head reducing position of above-mentioned steering-column tube.
As shown from the above technical solution, the tube head place of steering-column tube is arranged to the reducing shape that end diameter is big, the pipe shaft diameter is little, and fix, install steering bearing by the mode transition that adds sleeve pipe, can select the spring of the gauge member form of reduced size so on the one hand, on the other hand, can obtain the tube head profile of large-size again, be convenient to that combined switch is installed and satisfied the possibility of using the clock spring of bigger caliber.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
In conjunction with Fig. 1, turn to mandrel 10 by steering bearing 20 support fixation in the utility model, the tube head place of steering-column tube 30 is the reducing shape that end diameter is big, the pipe shaft diameter is little, the outer wall of described steering bearing 20 cooperates with a sleeve pipe 40, and described sleeve pipe 40 is positioned at the tube head reducing position of above-mentioned steering-column tube 30.Core content of the present utility model is exactly that steering-column tube 30 is adopted less caliber size, the position, termination is designed to the shape of reducing, the diameter of one of the position, termination section body is bigger in other words, install and fix steering bearing 20 by sleeve pipe 40 transition, its structure itself is very simple, just solve the difficult problem of design and production large scale specification steering bearing 20 so easily, solved the problem that adopts the clock spring of bigger caliber simultaneously again.
Described sleeve pipe 40 inwalls are provided with restriction steering bearing 20 axially movable snap rings 50 axial location that snap ring 50 will be realized steering bearing 20 exactly are set, and promptly prevent the end float misalignment of steering bearing 20.Install for convenience and maintenance, described snap ring 50 comparatively preferred construction is to adopt the rubber-like slotted ring.
For waiting straight tube of wall thickness, the caliber at the major diameter position of steering-column tube 30 is identical size certainly with described sleeve pipe 40, and both just can be fitted to each other like this.
Described sleeve pipe 40 is welded to connect with steering-column tube 30, and described steering bearing 20 and sleeve pipe 40 are close fit, and adopting above-mentioned fit system mainly is to consider the reliability of structure itself and the simple and convenient of processing.
In concrete enforcement, one board member is set on the end of steering-column tube 30, do not draw in the accompanying drawing, it mainly is the sectional shelf-unit that is used for fixing combined switch and clock spring or loudspeaker contact, combined switch is fixed on two ends, clock spring is fixed on the centre, and the opening of loudspeaker contact then directly is fixed on the support plate.
From the above mentioned, the utlity model has advantage simple in structure, that be convenient to process as can be known, also help assembling and maintenance simultaneously.
