Problems solved by technology

However, there is also a limit to increasing the diameter of the bushing
In particular, for wheels of the type in which drum brakes are provided in the hub, if the diameter of the hub is increased without changing the diameter of the hub, it is difficult to secure a mounting space for the drum brake.

Abstract

The present invention provides a wheel capable of preventing noise by simple structure and motorcycle having the wheel. The wheel comprises a wheel hub part(14b)made of light alloy and a shaft lining(18)breaking through the axle(13), wherein the shaft lining is made of metal having a strength higher than light alloy and is arranged on the axle center of the wheel hub part(14b)by casting, and turning effort transfers between the axle(13)and the wheel hub part(14b)by the shaft lining(18), wherein a friction coefficient lowering layer(19)is provided between the shaft lining(18)and the wheel hub part(14b)and is used for lowering the static friction coefficient between the shaft lining(18)and the wheel hub part(14b)formed by casting.

Description

technical field [0001] The present invention relates to a wheel and a motorcycle having the same wheel. More specifically, the present invention relates to a light alloy wheel through which driving force of an engine is transmitted via an axle. Background technique [0002] In a motorcycle, there are wheels of the type in which an engine driving force is transmitted to the wheel via an axle, and a rotational force at the time of engine braking operation is transmitted from the wheel to the engine side via the axle. In such a motorcycle, when the above-mentioned wheel is made of light alloy, there is a case where the axle is spline-fitted to the hub by casting an iron hub into the hub portion of the wheel. , thereby receiving the transmission of engine driving force and the like (for example, refer to Patent Document 1). In addition, in the above-mentioned casting operation, so-called gravity casting is generally used in which the above-mentioned iron bush is set on the axis...
