Method for immobilization, clutch, vehicle transmission, drive unit, and vehicle

A freewheel clutch for a vehicle, the clutch comprising:

• a first clutch component and a second clutch component that are situated coaxially with respect to one another and configured to be rotatably fixedly connected by a releasable mechanical contact between the first clutch component and the second clutch component when the clutch rotates in at least one predefined rotational direction;
• an actuator configured to displace one of the first clutch component and the second clutch component in an axial direction, as a result of which the mechanical contact between the first and second clutch components is separated;
• a first shaft to which the first clutch component is rotatably fixedly connected;
• and
• a second shaft that is hollow and coaxial with respect to the first shaft, wherein the second clutch component is rotatably fixedly connected to the second shaft, wherein the vehicle is an electric bicycle and the freewheel clutch is for the electric bicycle, wherein the actuator is configured to position a pin in a groove that is situated at a circumference of the clutch and between the first clutch component and the second clutch component, the groove being configured to guide the pin when the clutch rotates in the predefined rotational direction, the groove having a constriction in a direction of one of the first and second clutch components, the clutch being configured to displace one of the first clutch component and the second clutch component in the axial direction, using the pin and the constriction of the groove, when the clutch rotates in the predefined rotational direction.
