Abstract

A transmission for a motorcycle includes a housing, at least one shaft at least partially accommodated in the housing and which can be rotated relative to the housing, and a locking device having at least one locking element located in the housing. The at least one locking element is movable moved relative to the housing between at least one locking position in which the at least one locking element secures the shaft against rotation relative to the housing, and at least one release position in which the at least one locking element releases the shaft for rotation relative to the housing.

First claim

What is claimed is:

1. A transmission for a motorcycle, comprising:
a housing;
at least one shaft arranged at least partially in the housing and being rotatable relative to the housing;
a locking device having at least one locking element, the locking device being arranged in the housing and being rotatable relative to the housing between
at least one locked position in which the locking element secures the shaft against a rotation relative to the housing, and
at least one released position in which the shaft is released for rotation relative to the housing;

at least one operating element arranged at least partially outside the housing, the at least one operating element being configured to be actuated manually to move relative to the housing such that a movement of the locking element between the released position and the locked position is enabled; and
a securing device configured to be switched over between at least one secured state in which the at least one operating element is secured against movement relative to the housing, and at least one unsecured state in which the at least one operating element is movable,
wherein
the securing device includes at least one receiving unit configured to receive at least one signal in a radio-based manner from a remote control,
the at least one receiving unit is configured to, in response to actuation of the remote control, to switchover the securing device from the secured state into the unsecured state, and
the locking element has at least one locking gear connected fixedly to the shaft such that the at least one locking gear rotates with the shaft in an axially displaceable manner between the locked position and the released position.

2. The transmission according to claim 1 , wherein
the at least one receiving unit is configured
to detect whether a spacing between the remote control and the at least one operating element undershoots a predefined threshold value, and
to switchover the securing device out of the secured state into the unsecured state if the spacing of the remote control is determined to undershoot the predefined threshold value.

3. The transmission according to claim 2 , wherein
the securing device is arranged indirectly or directly on the housing, independent of the at least one operating element.

4. The transmission according to claim 2 , wherein
the securing device is arranged indirectly or directly on the at least one operating element, independent of the housing.

5. The transmission according to claim 1 , wherein
the at least one operating element is pivotable about a pivot axis relative to the housing such that the locking element moves between the released position and the locked position.

6. The transmission according to claim 5 , wherein
the at least one operating element is fixedly coupled to the locking element such that movements of the at least one operating element relative to the housing occur with movements of the locking element between the locked position and the released position.

7. The transmission device according to claim 1 , wherein
in the locked position, the locking gear interacts at least indirectly with the housing in a positive locking manner.

8. The transmission according to claim 7 , wherein
in the locked position, the locking gear interacts directly in a positively locking manner with the housing, with an element which is configured separately from the housing, or with both the housing and the element configured separately from the housing.

9. A motorcycle, comprising:
at least one drive motor; and
a transmission configured to be driven by the drive motor,
wherein the transmission includes
a housing;
at least one shaft arranged at least partially in the housing and being rotatable relative to the housing;
a locking device having at least one locking element, the locking device being arranged in the housing and being rotatable relative to the housing between
at least one locked position in which the locking element secures the shaft against a rotation relative to the housing, and
at least one released position in which the shaft is released for rotation relative to the housing;

at least one operating element arranged at least partially outside the housing, the at least one operating element being configured to be actuated manually to move relative to the housing such that a movement of the locking element between the released position and the locked position is enabled; and
a securing device configured to be switched over between at least one secured state in which the at least one operating element is secured against movement relative to the housing, and at least one unsecured state in which the at least one operating element is movable,

wherein
the securing device includes at least one receiving unit configured to receive at least one signal in a radio-based manner from a remote control,
the at least one receiving unit is configured to, in response to actuation of the remote control, to switchover the securing device from the secured state into the unsecured state, and

the locking element has at least one locking gear connected fixedly to the shaft such that the at least one locking gear rotates with the shaft in an axially displaceable manner between the locked position and the released position.

10. A transmission for a motorcycle, comprising:
a housing;
at least one shaft arranged at least partially in the housing and being rotatable relative to the housing;
a locking device having at least one locking element, the locking device being arranged in the housing and being rotatable relative to the housing between
at least one locked position in which the locking element secures the shaft against a rotation relative to the housing, and
at least one released position in which the shaft is released for rotation relative to the housing;

at least one operating element arranged at least partially outside the housing, the at least one operating element being configured to be actuated manually to move relative to the housing such that a movement of the locking element between the released position and the locked position is enabled; and
a securing device configured to be switched over between at least one secured state in which the at least one operating element is secured against movement relative to the housing, and at least one unsecured state in which the at least one operating element is movable,
wherein
the securing device includes at least one receiving unit configured to receive at least one signal in a radio-based manner from a remote control,
the at least one receiving unit is configured to, in response to actuation of the remote control, to switchover the securing device from the secured state into the unsecured state, and
the at least one receiving unit is configured
to detect whether a spacing between the remote control and the at least one operating element undershoots a predefined threshold value, and
to switchover the securing device out of the secured state into the unsecured state if the spacing of the remote control is determined to undershoot the predefined threshold value.
