Abstract
A bicycle hub structure includes: a hub body including a first clutch ring, a sprocket support body connecting to the hub body and including a second clutch ring, first magnets and a magnetic ring. The magnetic ring is disposed on an axial side of the second clutch ring far away from the hub body, and the first magnets are disposed on a side of the second clutch ring adjacent to the magnetic ring. The sprocket support body includes a first state and a second state. In the first state, the first magnets and the magnetic ring attract the first clutch ring, so that the first clutch ring is in contact with the second clutch ring, and in the second state, a magnetic attracting force of the first magnets and the magnetic ring on the first clutch ring is less than that in the first state.
Claims16
A bicycle hub structure, comprising:
- a hub body, comprising a first clutch ring;
- a sprocket support body, connecting to the hub body and comprising a second clutch ring, a plurality of first magnets and a magnetic ring, wherein the magnetic ring is disposed on an axial side of the second clutch ring far away from the hub body, and the plurality of first magnets are disposed on a side of the second clutch ring adjacent to the magnetic ring;
- and
- a hub axle, passing through the hub body and the sprocket support body, and having a plurality of bearings disposed between the hub axle and both the hub body and the sprocket support body, wherein
- a first torque transmission mechanism is disposed between the second clutch ring and the sprocket support body, and a second torque transmission mechanism is disposed between the first clutch ring and the second clutch ring;
- a third torque transmission mechanism is disposed between the first clutch ring and the hub body;
- and
- the sprocket support body comprises a first state and a second state, wherein in the first state, the first magnets and the magnetic ring attract the first clutch ring, to enable the first clutch ring to engage the second clutch ring, so that torque is transmitted from the sprocket support body to the hub body through the second clutch ring and the first clutch ring;
- and in the second state, a magnetic attracting force of the first magnets and the magnetic ring on the first clutch ring is less than that in the first state.
