Technical field

The present invention relates to a kind of motor vehicle devices, more precisely, being that the dress of motorcycle steering mechanism bearing a kind of changes the outfit It sets.

Background technique

The cooperation of present domestic market motorcycle steering mechanism (column) and seat tube generally uses thrust ball axis It holds and (is commonly called as ball).This thrust ball bearing can generate play in high vehicle speeds process emergency braking and cause to pacify to traveling Full harm.

Summary of the invention

The present invention mainly solves technical problem present in the prior art, to provide a kind of motorcycle steering mechanism axis The converter device held.

Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals:

A kind of converter device of motorcycle steering mechanism bearing includes a column and a seat tube, and the column can Rotationally be connected with the seat tube, which is characterized in that the bottom of the column be equipped with a front furcate steel bowl it is convex and One front furcate steel bowl fovea superior, the front furcate steel bowl is convex to be equipped with one first tapered roller bearing, institute between front furcate steel bowl fovea superior The bottom for the seat tube stated is recessed equipped with a front furcate steel bowl, and the front furcate steel bowl is recessed interior equipped with one second taper roller axis It holds.

As preferred embodiments of the present invention, the front furcate steel bowl fovea superior and the seat tube pass through interference fit Connection.

As preferred embodiments of the present invention, the front furcate steel bowl is recessed to pass through interference fit with the seat tube Connection.

The converter device of motorcycle steering mechanism bearing of the invention has the advantage that the motorcycle steering mechanism and vehicle The cooperation for erecting pipe uses tapered roller bearing, the thrust ball bearing of original vehicle is changed to tapered roller bearing, structure is convenient Reliably, simple and easy.

Detailed description of the invention

In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with It obtains other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of the converter device of motorcycle steering mechanism bearing of the invention；

Fig. 2 is the detail enlarged diagram of the a-quadrant in Fig. 1；

Fig. 3 is the detail enlarged diagram of the B area in Fig. 1.

Specific embodiment

The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.

As shown in Figure 1 to Figure 3, the converter device of the motorcycle steering mechanism bearing includes a column 1 and a seat tube 5, column 1 is rotationally connected with seat tube 5, can make vehicle that divertical motion occur.

The bottom of the column 1 is equipped with a front furcate steel bowl convex 2 and a front furcate steel bowl fovea superior 4, and the front furcate steel bowl convex 2 is with before It pitches and is equipped with one first tapered roller bearing 3 between steel bowl fovea superior 4, the bottom of the seat tube 5 is equipped with a front furcate steel bowl recessed 6, One second tapered roller bearing 7 is equipped in the front furcate steel bowl recessed 6.

In the hole of 5 upper end of cylindrical body force fit seat tube of the front furcate steel bowl fovea superior 4.

First tapered roller bearing 3 is made of outer ring and inner ring, and wherein outer ring and front furcate steel bowl convex 2 are interference fitted in one It rises；

Inner ring is together with the cylindrical body of front furcate steel bowl fovea superior 4 interference fit.

There is the internal screw thread of M25X1 at the center of front furcate steel bowl convex 2, and internal screw thread and column 1 pass through together with threaded engagement.It should In the hole of the lower end of the cylindrical body force fit seat tube 5 of front furcate steel bowl recessed 6.

Second tapered roller bearing 7 is also made of outer ring and inner ring, and wherein the hole interference of outer ring and front furcate steel bowl recessed 6 is matched It is combined, inner ring is together with the interference fit of column 1.

The cooperation of the motorcycle steering mechanism and seat tube uses tapered roller bearing, by the thrust ball axis of original vehicle It holds and is changed to tapered roller bearing, structure is convenient and reliable, simple and easy.

The converter device structure of the motorcycle steering mechanism bearing is simple, and effect is obvious, low in cost, practical.

Not limited to this, any change or replacement expected without creative work should all be covered in guarantor of the invention Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
