US 2026/0061774 A1 · BICYCLE COMPONENT

Abstract

A bicycle component for a bicycle freewheel unit, wherein the freewheel unit includes a rotary unit and a toothed disk device coupled with the rotary unit. The toothed disk device includes an end toothing with axial engagement components for engaging corresponding engagement components of another toothed disk device. The toothed disk device and the rotary unit are each configured as coupling components coupled to one another, and include a radial toothing each, for engaging with one another, and which are commonly rotatable. The rotary unit and the toothed disk device are movable in a peripheral direction relative to one another between a driving position and a rest position, so that prior to torque transmission starting, a coupling component is rotated in the driving direction about a clearance angle of at least 5°, until torque can be transmitted, when the two radial toothings have previously been in the rest position.

Dependent claims

A bicycle component for an at least partially muscle-powered vehicle

having at least one freewheel unit of a freewheel device;
wherein the freewheel unit comprises a rotary unit and a toothed disk device provided to be coupled with the rotary unit;
wherein the toothed disk device comprises an end toothing with axial engagement components, suitable for engaging with corresponding engagement components of another toothed disk device;
wherein the toothed disk device and the rotary unit are each configured as coupling components provided to be coupled with one another, and each comprising a radial toothing for engagement with one another and which are rotatable together around a central rotation axis;
in at least one configuration the rotary unit and the toothed disk device are movable in the peripheral direction relative to one another between a driving position and a rest position, such that prior to torque transmission starting, a coupling component is first rotated in the driving direction about a clearance angle of at least 5°, until torque can be transmitted, when the two radial toothings have previously been in the rest position.

A bicycle component for at least partially muscle-powered vehicles, comprising;

a hub axle, a freewheel device and two rotary units;
wherein one of the rotary units is connected with a hub shell and the other, with the rotor;
wherein the freewheel device comprises two freewheel units, one hub-side freewheel unit and one rotor-side freewheel unit;
wherein the hub-side freewheel unit comprises a rotary unit coupled with the hub shell and a hub-side toothed disk device;
and wherein the rotor-side freewheel unit comprises a rotary unit coupled with the rotor and a rotor-side toothed disk device;
wherein the hub-side and the rotor-side toothed disk devices each comprise an end toothing for engagement with one another, and which are pre-tensioned by means of at least one biasing device to an (axial) engaging position;
wherein at least one rotary unit and the pertaining toothed disk device are configured as separate coupling components, provided to be coupled with one another, and comprising one radial toothing each for engagement with one another, which are rotatable together around a central rotation axis;
at least one configuration, the rotary unit and the toothed disk device are movable in a peripheral direction relative to one another between a driving position and a rest position about a clearance angle of at least 5°, such that prior to torque transmission starting, a coupling component is first rotated in the driving direction, until torque is, or can be, transmitted, when the two radial toothings have previously been in a rest position.
