Description

Bearing assembling structure of steering column

Technical Field

The utility model relates to a steering column for the vehicle, specifically speaking are steering column's bearing assembly structure.

Background

The steering column is an important composition structure of a vehicle steering system and completes the steering of a vehicle. The steering column comprises a support, a support sleeve 20, a bearing 30 and a rotating shaft 40, wherein the support is arranged outside the support sleeve 20, the rotating shaft 40 is arranged in the support sleeve 20, and the bearing 30 is sleeved on the rotating shaft 40 and is arranged in a bearing hole of the support sleeve.

The bearing mounting modes of the steering column in the prior art are mainly divided into two modes,

firstly, the bearing is pressed into the bearing hole of the supporting sleeve in an interference mode, and the snap ring 50 is arranged in the bearing hole of the supporting sleeve to block the outer ring of the bearing, so that the effect of preventing the bearing from being separated from the bearing hole of the supporting sleeve is achieved. The problem that exists is that the assembly of snap ring is more difficult, and in order to prevent that the bearing from being crushed by the snap ring, need to leave certain clearance between snap ring and the bearing, the clearance makes the bearing produce the phenomenon of swarming.

Secondly, be equipped with a plurality of spacing pieces 60 on the support sleeve lateral wall, inwards buckle the spacing piece for spacing to the bearing. The problem that exists is that, spacing piece after buckling can't with bearing surface in close contact with, has certain clearance between spacing piece after buckling and the bearing, the bearing is moved easily.

There is a need for a bearing limiting structure that can prevent the bearing from moving in a string manner without damaging the bearing.

Disclosure of Invention

The utility model aims at providing a steering column's bearing assembly structure, this structure is with low costs, simple structure, can be better prevent that the bearing from moving.

The technical scheme of the utility model:

the utility model provides a steering column's bearing assembly structure, includes supporting sleeve, pivot, bearing, in the supporting sleeve was arranged in to the pivot, be connected through the bearing between pivot and the supporting sleeve, be equipped with a plurality of bearing stopper on the inboard outer fringe of supporting sleeve, bearing surface side is arranged in to the bearing stopper.

The bearing limiting blocks are arranged between the supporting sleeve and the bearing and on the outer surface side of the bearing.

The utility model has the advantages that:

1. this application bearing assembly structure uses the bearing stopper to the better spacing of bearing, has reduced the clearance between bearing and snap ring or the spacing piece among the prior art moreover greatly, prevents that the bearing from moving. The assembly difficulty is low, the process is simple, and the cost is saved.

2. The bearing assembly structure is simple in structure, low in cost and wide in adaptability, and can be widely applied to all designs of steering columns with the requirements.

Fig. 4 is a schematic view of a bearing assembly structure of a steering column in the prior art.

Fig. 5 is a schematic view of another prior art bearing assembly for a steering column.

The mark in the figure is:

1. a support sleeve; 2. a rotating shaft; 3. a bearing; 4. bearing stopper.

Detailed Description

Steering column among the prior art is spacing through the spacing limit of buckling or snap ring of the inside of support sleeve for preventing the bearing from moving, nevertheless because technical reason or prevent reasons such as snap ring crushing bearing for there is certain clearance between bearing and spacing limit or the snap ring, makes the bearing move in cluster easily. In order to better solve the problems in the prior art, the invention provides a bearing assembly structure of a steering column.

The present application will now be described in detail with reference to the accompanying drawings:

the utility model provides a steering column's bearing assembly structure, includes supporting sleeve 1, pivot 2, bearing 3, in supporting sleeve 1 was arranged in to pivot 2, be connected through bearing 3 between pivot 2 and the supporting sleeve 1, be equipped with a plurality of bearing stopper 4 on the inboard outer fringe of supporting sleeve 1, bearing stopper 4 and supporting sleeve 1 fixed connection, the bearing surface side can be arranged in to the bearing stopper, and the bearing stopper also can partly arrange in between supporting sleeve and the bearing, and the bearing surface side is arranged in to a part, and the bearing can be better carry on spacingly to the bearing. The bearing limit blocks 4 are uniformly distributed on the circumference of the outer edge of the inner side of the support sleeve 1, preferably 3 or more than 3.

This steering column's bearing assembly structure, simple structure, low cost, easy realization, the suitability is strong, can be better carry on spacingly to the bearing moreover.

The installation process comprises the following steps:

the bearing is pressed into the bearing hole of the supporting sleeve in an interference mode, a plurality of bearing limiting blocks are fixedly installed on the circumference of the inner edge of the supporting sleeve, and the bearing limiting blocks are arranged between the supporting sleeve and the bearing and on the outer surface side of the bearing, so that the function of increasing the releasing force of the bearing is achieved, and the function of preventing the bearing from releasing is achieved.

The bearing limiting block can be fixedly connected with the inner edge of the supporting sleeve in a welding or other mode, or the bearing limiting block is formed in a riveting mode, so that the bearing hole area of the supporting sleeve is deformed, the effect of increasing the releasing force of the bearing is achieved, and the effect of preventing the bearing from releasing can be achieved.

However, any modifications, equivalent changes and variations of the above embodiments made according to the technical essence of the present invention are still within the protection scope of the technical solution of the present invention.

Claims
