摘要： A control system for and a method of controlling a wheel hub clutch for a wheel hub. The control system includes: a stator; a translator having a permanent magnet; and wiring electrically connecting the stator to an electric power source. The stator is selectively powered through controlled electric power carried by the wiring so as to control translation of the translator through interaction between the stator and the permanent magnet of the translator, and the translation of the translator is controlled between an engaged state and a disengaged state. In the engaged state, a plurality of locking members are engaged with a plurality of notches of a selectively rotatable notch plate whereby the plurality of locking members are in a plurality of pockets of a rotatable pocket plate corresponding to the plurality of notches.

摘要： A sprocket assembly is described. The assembly includes a sprocket having an outer wheel with engaging members connected to a central hub including a first hub opening having a first diameter and a second hub opening having a smaller second diameter, and a hub including an alignment portion and an engagement portion that together define an axle opening for receiving an axle of a vehicle. The alignment portion incudes a smooth outer surface sized to be press fit into the second hub opening, and the engagement portion includes forming splines positioned to deform an inner surface of the first hub opening as the alignment portion is press fit into the second hub opening to form engagement splines on the inner surface that correspond to the splines. The hub is formed from a first material and the sprocket is formed from a less durable second material.

摘要： A wheel hub clutch includes: a notch plate; a pocket plate having pockets and plunger passages in communication with the pockets; locking members carried in the pocket plate pockets; and plungers carried in the pocket plate plunger passages and configured to drive the locking members into engagement with the notches in the notch plate. The clutch also may include a translator with a permanent magnet that cooperates with an electromagnet of a stator to translate the translator. The translator may be coupled to the locking members to translate them into and out of engagement with the notch plate. Also disclosed is a wheel end system including the wheel hub clutch, a drivetrain including the wheel end system and wheel hub clutch, and a vehicle including the drivetrain.

摘要： A planar ratchet assembly is provided for a human-powered vehicle, and includes a first ratchet member and a second ratchet member. The first ratchet member includes an axial surface defining a plurality of first serrated teeth having a first driving surface and a first non-driving surface. At least one of the first non-driving surfaces includes a convex curved surface that has a radius of curvature of at least 0.5 mm. The second ratchet member includes an axial surface defining a plurality of second serrated teeth having a second driving surface and a second non-driving surface. The first ratchet member and the second ratchet member rotate together in a driving direction. At least one of the first ratchet member and the second ratchet member moves in an axial direction to permit relative rotation between the first ratchet member and the second ratchet member in a non-driving direction.

摘要： A bicycle drive assembly may include an axle, a hub shell rotatably mounted on the axle by a first bearing, a free hub rotatably mounted on the axle by a second bearing, and a ratchet mechanism releasably coupling the free hub to the hub shell to transmit torque from the free hub to the hub. The ratchet mechanism may include a first ratchet ring having an inner surface joined to the hub shell for rotation with the hub shell and a second ratchet ring having an inner surface joined to the free hub for rotation with the free hub. The first ratchet ring and the second ratchet ring encircle and radially overlap the first bearing and the second bearing, respectively. At least one spring resiliently biases the first ratchet face and the second ratchet face into engagement to transmit torque from the free hub to the hub shell.

摘要： A bicycle rear sprocket comprises a sprocket body, a plurality of sprocket teeth, an opening, and a torque-transmitting structure. The plurality of sprocket teeth extends radially outwardly from the sprocket body with respect to a rotational center axis of the bicycle rear sprocket. The opening has a minimum diameter that is smaller than a minimum outer diameter of a sprocket support body of a bicycle rear hub assembly. The torque-transmitting structure includes at least ten torque-transmitting teeth configured to directly or indirectly transmit a pedaling torque to the sprocket support body of the bicycle rear hub assembly.

摘要： A freehub of a bicycle contains: a body fitted and rotating on a rotary shaft. A receiving sleeve is connected with the body and fitted on the rotary shaft, and the receiving sleeve includes an accommodation holder configured to accommodate a freewheel. A ratchet assembly is mounted between the body and the receiving sleeve, the ratchet assembly includes multiple chutes, and a central axis of a respective chute is not parallel to a central axis of the rotary shaft. A toothed ring is fitted between the fixing element and the body. The ratchet assembly includes multiple teeth, multiple engagement elements, and multiple resilient elements. A respective resilient element abuts against the respective chute and a respective engagement element, such that the respective engagement element is urged by the respective resilient element to linearly move toward the respective tooth so as to engage with the respective tooth.
