Abstract

A saddle riding type vehicle driven by a straddling rider, comprises a wheel including a wheel member having an annular rim, and a hub formed centrally of the rim to have a through hole formed at a center of rotation, a bearing attached to an inner circumferential surface of the through hole, and a tire attached to the rim; a wheel support for rotatably supporting the wheel with an axle inserted in the through hole; a sensor rotor mounted on the hub using the inner circumferential surface of the through hole as reference; and a wheel speed sensor for detecting rotation of the sensor rotor.

First claim

What is claimed is:

1. A saddle riding type vehicle driven by a straddling rider, comprising:
a wheel including
a wheel member having
an annular rim, and
a hub formed centrally of the rim to have a through hole formed at a center of rotation of the hub,

a bearing attached to an inner circumferential surface that defines the through hole, and
a tire attached to the rim;

an axle inserted in the through hole;
a wheel support for rotatably supporting the wheel with the axle;

a sensor rotor mounted on the hub using the inner circumferential surface that defines the through hole as a reference;
a wheel speed sensor for detecting rotation of the sensor rotor; and
a spacer including a projection projecting from a part of the spacer toward the hub, and a mount portion projecting from the part of the spacer in a direction away from the projection, the spacer being attached with an outer circumferential surface of the projection positionally adjusted to the inner circumferential surface that defines the through hole;
wherein the sensor rotor has an annular shape projecting outward, and is mounted with an inner circumferential surface thereof positionally adjusted to an outer circumferential surface of the mount portion.

2. The saddle riding type vehicle according to claim 1 , further comprising a dust seal in the through hole and disposed between an inner circumferential surface of the spacer and an outer lateral surface of the bearing.

3. The saddle riding type vehicle according to claim 2 , wherein the wheel member is formed of a magnesium alloy, the sensor rotor is formed of iron, and the spacer is formed of an aluminum alloy.

4. The saddle riding type vehicle according to claim 3 , wherein the sensor rotor has a plurality of openings formed therein.

5. The saddle riding type vehicle according to claim 4 , wherein the wheel speed sensor is arranged to magnetically detect a presence or an absence of the openings within a predefined area.

6. The saddle riding type vehicle according to claim 2 , wherein the sensor rotor has a plurality of openings formed therein.

7. The saddle riding type vehicle according to claim 6 , wherein the wheel speed sensor is arranged to magnetically detect a presence or an absence of the openings within a predefined area.

8. The saddle riding type vehicle according to claim 1 , wherein the wheel member is formed of a magnesium alloy, the sensor rotor is formed of iron, and the spacer is formed of an aluminum alloy.

9. The saddle riding type vehicle according to claim 8 , wherein the sensor rotor has a plurality of openings formed therein.

10. The saddle riding type vehicle according to claim 9 , wherein the wheel speed sensor is arranged to magnetically detect a presence or an absence of the openings within a predefined area.

11. The saddle riding type vehicle according to claim 1 , wherein the sensor rotor has a plurality of openings formed therein.

12. The saddle riding type vehicle according to claim 8 , wherein the wheel speed sensor is arranged to magnetically detect a presence or an absence of the openings within a predefined area.

13. A saddle riding type vehicle driven by a rider, comprising:
a wheel including
a wheel member having
an annular rim, and
a hub formed proximate the rim to have a through hole formed at a center of rotation of the hub,

a bearing attached to an inner circumferential surface that defines the through hole, and
a tire attached to the rim;

an axle inserted in the through hole;
a wheel support for rotatably supporting the wheel via the axle;

a sensor rotor mounted on the hub to be coaxial with the center of rotation and at a predetermined position with respect to the through hole;
a wheel speed sensor for detecting rotation of the sensor rotor; and
a spacer including a projection projecting from a part of the spacer toward the hub, and a mount portion projecting from the part of the spacer in a direction away from the projection, the spacer being attached with an outer circumferential surface of the projection positionally adjusted to the inner circumferential surface that defines the through hole;
wherein the sensor rotor has an annular shape projecting outward, and is mounted with an inner circumferential surface thereof positionally adjusted to an outer circumferential surface of the mount portion.
