摘要： A freewheel of a vehicle, in particular a two-wheeler, includes (i) a crankshaft, (ii) an output shaft having a first gear cog, (iii) a freewheel element having a second gear cog, and (iv) a friction element. The first gear cog and the second gear cog are configured to, when engaged with each other, effect a torque transfer between the output shaft and the freewheel element. The freewheel element is arranged to be displaceable in an axial direction on the crankshaft. The freewheel element is arranged to be non-rotatable relative to the crankshaft in the circumferential direction. The freewheel element and the friction element are connected to one another by means of a helical mechanism, which is configured to effect a translational displacement of the freewheel element and the friction element relative to one another when the freewheel element and friction element rotate relative to one another.

摘要： A pedaled drivetrain includes a drive mechanism, a wheel, a freewheel hub, and a locking mechanism. The wheel has a rotational axis. The freewheel hub connects the drive mechanism to the wheel, and the freewheel hub transmits torque from the drive mechanism to the wheel in a first rotational direction around the rotational axis. The locking mechanism has a locked state and an unlocked state. The locked state rotationally fixes a component of the drive mechanism to the wheel relative to the rotational axis.

摘要： A clutch or brake system for a torque transmission. The clutch or brake system includes a first rotatable unit connectable to an input or output, including at least one first abutment surface and a second rotatable unit connectable to an output or input, respectively, including at least one second abutment surface arranged for selectively engaging the first abutment surface. The first and second abutment surfaces are adapted to each other so as to allow disengaging under load. The system includes a third rotatable unit including at least one retaining member, the third unit being arranged for selectively being in a first rotational position or a second rotational position relative to the second rotatable unit, wherein the at least one retaining member in the first rotational position locks the at least one second abutment surface for rotationally coupling the second rotatable unit to the first rotatable unit.

摘要： Bicycle hub includes a shell rotatably supported relative to a hub axle, a rotor rotatably supported by two rotor bearings, and a freewheel device having two interacting freewheel components: a hub-side freewheel component and a rotor-side freewheel component. The freewheel components each include axial engagement elements and are axially movable relative to one another between a freewheel position and an engaging, driving torque position. The hub-side freewheel component includes a threaded axial body section and is screwed into the hub shell. The hub-side freewheel component has an axial, annular surface on which the axial engagement elements are configured. The rolling members of a hub bearing show a defined accommodation inside the hub-side freewheel component to support the shell relative to the hub axle. The hub-side freewheel component includes a tool contour which couples to an adapted tool for releasing the screw connection of the hub-side freewheel component with the shell.

摘要： A drive unit for an electrically assisted bicycle includes a one-way clutch including an inner member linked to an end of a connecting shaft and an outer member linked to a drive sprocket wheel. The inner member includes clutch pawls and a boss. The outer member includes clutch teeth that are able to engage with the clutch pawls and an extension to be coupled to the drive sprocket wheel. The extension includes a recess to accept the boss at an inner member side thereof. The recess has an inner peripheral surface that is able to slide against an outer peripheral surface of the boss.

摘要： An electro-mechanical clutch apparatus includes a stationary member (22,122) having a center portion extending along an axis A and a stationary coil assembly (34,134) fixed about the center portion. A rotatable member (46,146) extends along the axis A and includes an annular projection (52,152) radially spaced from the coil assembly. A ratchet surface (29,129) presents a plurality of teeth disposed in axially aligned and radially spaced relationship with the annular projection. The rotatable member includes a magnetic pole piece (62,162) disposed in radially spaced and concentrically aligned relationship with said coil assembly. The rotatable member includes a locking member (58,158) pivotably attached to the annular projection and pivotable between an engaged position in engagement with one of the teeth in response to the coil assembly being de-energized and a released position displaced from engagement with the teeth and attracted towards the magnetic pole piece in response to the coil assembly being energized.
