Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1 to 3, the device for assembling and replacing the bearing of the steering mechanism of the motorcycle comprises a vertical post 1 and a frame vertical pipe 5, wherein the vertical post 1 is rotatably connected with the frame vertical pipe 5 to enable the vehicle to perform steering movement.
The bottom of the upright column 1 is provided with a front fork steel bowl upper convex 2 and a front fork steel bowl upper concave 4, a first tapered roller bearing 3 is arranged between the front fork steel bowl upper convex 2 and the front fork steel bowl upper concave 4, the bottom of the frame vertical pipe 5 is provided with a front fork steel bowl lower concave 6, and a second tapered roller bearing 7 is arranged in the front fork steel bowl lower concave 6.
The cylinder of the concave 4 on the front fork steel bowl is pressed into the hole at the upper end of the frame vertical pipe 5 in an interference way.
The first tapered roller bearing 3 consists of an outer ring and an inner ring, wherein the outer ring and the front fork steel bowl are in interference fit with each other through a convex part 2;
the inner ring is in interference fit with the cylinder of the concave 4 on the front fork steel bowl.
The center of the upper flange 2 of the front fork steel bowl is provided with M25X1 internal threads, and the internal threads and the upright post 1 are matched together through a screw. The cylinder of the front fork steel bowl concave 6 is pressed into the hole at the lower end of the frame vertical pipe 5 in an interference way.
The second tapered roller bearing 7 also comprises an outer ring and an inner ring, wherein the outer ring is in interference fit with a hole of a concave 6 of the front fork steel bowl, and the inner ring is in interference fit with the upright post 1.
The motorcycle steering mechanism and the frame vertical pipe are matched by adopting the tapered roller bearing, the thrust ball bearing of the original vehicle is changed into the tapered roller bearing, and the structure is convenient and reliable, and is simple and easy to implement.
The device for assembling and replacing the bearing of the steering mechanism of the motorcycle is simple in structure, obvious in effect, low in cost and high in practicability.
Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
