Abstract
A shift device is provided. The shift device comprises a first member axially movably supported on a shaft, a second member axially movably supported on the shaft, and an elastic member arranged on the shaft and elastically compressible in the axial direction of the shaft. The second member is engaged with the first member such that an axial movement of the first member is transmitted to the second member and vice versa via the elastic member.
Claims13
A shift device, comprising:
- a first member axially movably supported on a shaft,
- a second member axially movably supported on the shaft, and
- an elastic member arranged on the shaft and elastically compressible in an axial direction of the shaft, wherein
- the second member is engaged with the first member such that an axial movement of the first member is transmitted to the second member and vice versa via the elastic member,
- the elastic member, by being compressed, allows relative axial movement in both a first axial direction and an opposite second axial direction between the first member and the second member so that one of the first member and the second member is displaced from an initial position relative to the other of the first member and the second member, and
- the elastic member, in a compressed state, exerts an urging force on the first member and the second member urging the one of the first member and the second member towards the initial position relative to the other of the first member and the second member.
3 more elements
A shifting system comprising:
- an actuator,
- a shift member for shifting a shift sleeve configured to engage and disengage gears of a transmission, and
- a shift device that comprises:
- a first member axially movably supported on a shaft,
- a second member axially movably supported on the shaft, and
- an elastic member arranged on the shaft and elastically compressible in an axial direction of the shaft;
- wherein the actuator is in communication with one of the first member and the second member of the shift device, and
- the shift member is in communication with the other of the first member and the second member of the shift device,
- when the actuator is operated, the one of the first member and the second member is moved in the axial direction by a specific amount,
- when axial movement of the shift member is not restricted, the axial movement of the one of the first member and the second member is transmitted to the other of the first member and the second member so that the other of the first member and the second member is moved in the axial direction by the specific amount,
- when axial movement of the shift member is restricted, the other of the first member and the second member is displaced from an initial position relative to the one of the first member and the second member, thereby compressing the elastic member, and
- when restriction on the axial movement of the shift member is released, the elastic member urges the other of the first member and the second member to the initial position relative to the one of the first member and the second member, thereby axially moving the shift member by the specific amount so as to perform a shifting operation.
