Abstract

A wheel equipped with a sensing device includes a wheel and a sensing device. The sensing device includes a displacement extraction member, a to-be-detected part, and a detecting part. One radial end portion of the displacement extraction member is supported to one radial end-side portion of the wheel. The other radial end portion of the displacement extraction member is a free end. The to-be-detected part is provided to one of the other radial end-side portion of the wheel and the other radial end portion of the displacement extraction member. The detecting part is provided to the other of the other radial end-side portion of the wheel and the other radial end portion of the displacement extraction member, and is arranged in a vicinity of the to-be-detected part. An output of the detecting part changes in association with a change in positional relationship between the detecting part and the to-be-detected part.

Claims

1. A wheel equipped with a sensing device comprising:

a wheel, and

a sensing device,

wherein the sensing device comprises a displacement extraction member, a to-be-detected part, and a detecting part,

wherein one radial end portion of the displacement extraction member is supported to one radial end-side portion of the wheel,

wherein the other radial end portion of the displacement extraction member is a free end,

wherein the to-be-detected part is provided to one of the other radial end-side portion of the wheel and the other radial end portion of the displacement extraction member,

wherein the detecting part is provided to the other of the other radial end-side portion of the wheel and the other radial end portion of the displacement extraction member, and is arranged in a vicinity of the to-be-detected part,

wherein an output of the detecting part changes in association with a change in positional relationship between the detecting part and the to-be-detected part, and

wherein the displacement extraction member comprises a pseudo-spoke which is arranged at at least one circumferential place and which has one radial end portion supported to one radial end-side part of the wheel.

2. The wheel equipped with a sensing device according to claim 1, wherein the output of the detecting part changes in association with a change in positional relationship in a circumferential direction of the wheel between the detecting part and the to-be-detected part.

3. The wheel equipped with a sensing device according to claim 1,

wherein the displacement extraction member comprises:

a plurality of pseudo-spokes which is arranged at a plurality of circumferential places and each of which has one radial end portion supported to the one radial end-side part of the wheel; and

an annular coupling part which couples the other radial end portions of pseudo-spokes each other.
