Problems solved by technology

Since the existing connection structure between the steering column and the upper connecting plate is only a single fit of the shaft and the hole, the multiple degrees of freedom of the steering column cannot be well controlled. The steering column rotates or moves up and down relative to the upper link plate, resulting in poor rotation of the front of the car and large errors in the steering angle of the front, which not only affects riding comfort, but also poses certain safety hazards

Embodiment 1

[0014] Embodiment 1, as shown in Fig. 1, Fig. 2 and Fig. 3, the present invention is composed of a direction column 1 and an upper connecting plate 2, and the upper connecting plate 2 is provided with a via hole 2a for the direction column 1 to pass through. The upper part of the connecting plate via hole 2a is a tapered hole with a small top and a large bottom, and the lower part is a straight through hole, and the diameter of the through hole is not less than the maximum diameter of the tapered hole. In this embodiment, the diameter of the through hole is slightly larger than that of the tapered hole. The largest diameter (as shown in Figure 3), and a through groove 2b is opened along the axis on the wall of the through hole and the tapered hole.

[0015] As shown in Figures 1 and 4, the upper part of the direction column 1 is a threaded section, and a section of the column body of the direction column 1 adjacent to the threaded section is a cone section, which is adapted to ...

Embodiment 2

[0017] Embodiment 2. In this embodiment, the upper part of the via hole 2a of the upper connecting plate is a tapered hole with a small upper part and a larger lower part, and the lower part is a straight through hole, and the diameter of the straight through hole is equal to the maximum diameter of the tapered hole. The rest of the present embodiment Same as Example 1.

Abstract

The steering device of motorcycle includes one directional column, one upper connecting plate with one through hole for the directional column to penetrate, and one semi-circular key between the directional column and the upper connecting plate. The directional column has one upper thread section and one lower conic section. The through hole in the upper connecting plate has one upper conic part and one lower straight part in the diameter not smaller than the maximum diameter of the conic part, with conic part being matched with the conic section in the directional column. The present invention has reasonable structure, high connection reliability between the directional column and the upper connecting plate and other advantages.

Description

technical field [0001] The invention belongs to the technical field of motorcycles, and in particular relates to a motorcycle head steering device. Background technique [0002] The threaded section at the upper end of the motorcycle steering column passes through the through hole on the upper connecting plate and is locked by a nut. The upper connecting plate is fixedly connected to the front of the motorcycle. The front wheel can drive the front wheel to swing left and right through the upper connecting plate and the steering column. To realize motorcycle turning. Since the existing connection structure between the steering column and the upper connecting plate is only a single fit of the shaft and the hole, the multiple degrees of freedom of the steering column cannot be well controlled. The steering column rotates or moves up and down relative to the upper link plate, resulting in poor rotation of the front of the car and a large error in the steering angle of the front...
