Double disc brake disc wheel device for motorcycle

Abstract

The utility model relates to a double-disc brake disc wheel device of a motorcycle, which comprises a wheel unit and a valve element. The wheel unit includes a wheel frame and two disc brake discs arranged on both sides of the wheel frame. The wheel frame has an inclined surface located on the center line of the width of the wheel frame, and a first wall surface and a second wall surface extending from the inclined surface on both sides, and the junction of the second wall surface and the inclined surface is higher than The junction of the first wall and the inclined surface. The valve element includes a connection portion arranged on the inclined surface, and an extension portion connected to the connection portion and on the same side as the first wall surface, so that the extension portion of the valve element can be exposed to the outside world and inflated At this time, an air nozzle can be directly placed on the extension part to prevent the valve element from being covered by the disc brake disc, so it is more convenient to inflate.

Description

【Technical field】 [0001] The invention relates to a wheel device, in particular to a double-disc brake disc wheel device for a motorcycle. 【Background technique】 [0002] refer to figure 1 , the existing single disc brake disc wheel device comprises a wheel frame 11, a tire 12 arranged on the wheel frame 11, an air chamber 13 jointly defined by the wheel frame 11 and the tire 12, an air chamber 13 arranged on the wheel frame 11 The disc brake disc 14 on the side, and an air valve 15 which is arranged on the wheel frame 11 and can communicate with the air chamber 13 . The air valve 15 includes a connection portion 151 connected to the wheel frame 11 and an extension portion 152 extending outward for inflation. Usually, in the existing single-disc brake disc wheel device, the extension 152 of the air valve 15 will face the side where the disc brake disc 14 is not provided, so as to prevent the air nozzle from being blocked by the disc brake disc 14 when inflating. cause inc...

AI Technical Summary

Problems solved by technology

That is to say, due to the problem that the valve 15 will be covered by the disc brake disc 14, it is impossible to arrange the double disc brake disc 14 on the wheel frame with a small wheel diameter.

[0004] Based on the above, the existing single-disc brake disc wheel device has the disadvantage of insufficient braking force, while the existing dual-disc brake disc wheel device can only be applied to the wheel frame 11 with a large wheel diameter, so each has its own shortcomings and needs to be improved. And how to make the wheel frame with small wheel diameter can be equipped with double-disc brake disc 14 is a problem that the motorcycle industry needs to solve.
