Abstract
A spigot joint part of a wheel hub has a cylindrical outer peripheral surface. The wheel mounting structure includes a collared member having a collar part to be press-fitted into and fixed to the spigot joint part, which is formed at a position away from an end part of the spigot joint part by a predetermined distance to protrude outward in a radial direction of the collared member. An annular protruding part is formed on a part of an inner peripheral surface of a center hole of a wheel to protrude toward a center of the wheel. In a state where the wheel is fixed to the flange part by using hub bolts, a fitting part and the annular protruding part are spigot-fitted. In a state where the hub bolts are removed, the annular protruding part is locked by the collar part.
Claims13
A wheel mounting structure configured to mount a wheel to a wheel hub for a vehicle,
- the wheel hub comprising:
- a hub axle part;
- a flange part being a disc-shaped part extending from the hub axle part in parallel to a plane perpendicular to a rotation axis of the wheel hub, the flange part having a fixing surface configured to fix the wheel by using a plurality of hub bolts on a vehicle-body outer side of the vehicle;
- and
- a spigot joint part being a part having a cylindrical shape with the rotation axis as a center axis, which is formed to protrude from the hub axle part to the vehicle-body outer side with respect to the flange part,
- wherein the spigot joint part has a cylindrical outer peripheral surface with the rotation axis as a center axis and a cylindrical inner peripheral surface with the rotation axis as a center axis.
- wherein a collared member being a member having a cylindrical shape, which has a collar part formed to protrude outward in a radial direction of the collared member, is inserted into and fixed to the cylindrical inner peripheral surface from the vehicle-body outer side, and the collar part is formed at a position separated from an end part of the spigot joint part by a predetermined distance when the collared member is inserted into and fixed to the spigot joint part,
- wherein the wheel has:
- a center hole formed in a center of the wheel to allow the spigot joint part to be inserted therethrough;
- a plurality of bolt holes formed around the center hole to allow the plurality of hub bolts to be inserted therethrough;
- and
- an annular protruding part formed on a part of an inner peripheral surface of the center hole, which is positioned on a hub mounting surface side of the wheel, to protrude toward the center of the wheel,
- wherein a fitting part having the cylindrical outer peripheral surface and the annular protruding part are spigot-fitted in a state where the wheel is fixed to the flange part by using the plurality of hub bolts, and
- wherein the annular protruding part is locked by the collar part in a state where the fixing of the wheel by using the plurality of hub bolts is released.
