Freewheel of a vehicle

A freewheel of a vehicle, comprising:

• a first shaft;
• a second shaft including a first gear cog;
• a freewheel element including a second gear cog;
• and
• a friction element;
• and
• a return element which is arranged and configured to apply a return force to the freewheel element, wherein:
• the first gear cog and the second gear cog are configured to, when engaged with each other, effect a torque transfer between the second shaft and the freewheel element,
• the freewheel element is arranged to be displaceable in the axial direction on the first shaft,
• the freewheel element is arranged to be non-rotatable relative to the first shaft in the circumferential direction,
• the freewheel element and the friction element are connected to each other by way of a helical mechanism which is configured to effect a translational displacement of the freewheel element and the friction element relative to each other during relative rotation of the freewheel element and the friction element, and
• the return force is oriented towards the first gear cog of the second shaft.

A freewheel of a vehicle, comprising:

• a first shaft;
• a second shaft including a first gear cog;
• a freewheel element including a second gear cog;
• and
• a friction element,
• wherein the first gear cog and the second gear cog are configured to, when engaged with each other, effect a torque transfer between the second shaft and the freewheel element,
• wherein the freewheel element is arranged to be displaceable in the axial direction on the first shaft,
• wherein the freewheel element is arranged to be non-rotatable relative to the first shaft in the circumferential direction,
• wherein the freewheel element and the friction element are connected to each other by way of a helical mechanism which is configured to effect a translational displacement of the freewheel element and the friction element relative to each other during relative rotation of the freewheel element and the friction element, and
• wherein a predetermined force closure in the circumferential direction is formed between the second shaft and the friction element.

A freewheel of a vehicle, comprising:

• a first shaft;
• a second shaft including a first gear cog;
• a freewheel element including a second gear cog;
• and
• a friction element,
• wherein the first gear cog and the second gear cog are configured to, when engaged with each other, effect a torque transfer between the second shaft and the freewheel element,
• wherein the freewheel element is arranged to be displaceable in the axial direction on the first shaft,
• wherein the freewheel element is arranged to be non-rotatable relative to the first shaft in the circumferential direction,
