CN201151457Y - brake disc - Google Patents

Abstract

A brake disc is provided with a plurality of notches; wherein the notch is arranged at the edge of the disk surface of the disk. The utility model discloses have intermittent type nature's braking effect, and avoid unnecessary danger.

Description

brake disc

technical field

The utility model relates to a braking device of a motorcycle, in particular to a braking disc with intermittent braking effect and avoiding unnecessary danger.

Background technique

Please refer to Figure 1 to Figure 3, the front and rear disc surfaces of the conventional brake discs are almost flat, occasionally designed with a hollow shape, and the brake pads are clamped on the disc surface near the edge of the disc. action, and then achieve the effect of braking. Since the contact area between the brake pads and the surface of the disc is large, the resulting friction is also relatively improved, making the braking effect very good, and the effect of braking and stopping can be achieved, but it is also Therefore, often there are many motorcyclists under the situation of emergency braking, and cause unnecessary accidental danger.

Utility model content

The main technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art, and provide a brake disc, which has an intermittent braking effect and avoids unnecessary dangers.

The technical scheme that the utility model solves its technical problem adopts is:

A brake disc is characterized in that the disc surface is provided with a plurality of notches.

In the aforementioned brake disc, the notch is located near the edge of the disc surface of the disc.

The beneficial effect of the utility model is that it has intermittent braking effect and avoids unnecessary danger.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a front view of a conventional brake disc.

Fig. 2 is a side view of a conventional brake disc.

Fig. 3 is a sectional view of a conventional brake disc.

Fig. 4 is a front view of the utility model.

Explanation of symbols in the figure:

10 brake discs

20 brake discs

21 discs

22 gaps

30 brake pads

Detailed ways

Please refer to FIG. 4 and FIG. 6, the disc surface 21 of the brake disc 20 is provided with a plurality of notches 22, and the notches 22 are located near the edge of the disc surface;

When the brake shoe 30 intends to pinch the brake disc 20, the brake shoe 30 will make a pinch action along the disc surface 21 and the gap 22 of the brake disc 20. Because of this situation, there will be a difference in size. The frictional force, coupled with a continuous action, produces intermittent braking effect until the brakes are completely stopped, so that the wheels will not be braked immediately, and unnecessary dangers will be avoided.

Claims (2)

1. A brake disc, characterized in that the disc surface is provided with a plurality of notches. 2. The brake disc according to claim 1, characterized in that, the notch is provided near the edge of the disc surface of the disc.
