Abstract
A transmission shifting assistance device, in particular for a motorcycle, is provided. The transmission shifting assistance device, which allows shifting when the clutch is closed, includes a housing, a piston arranged in the housing, and at least one pressure spring provided in the housing. The piston may be moved relative to the housing by compressing at least one pressure spring. Furthermore, transmission shifting assistance device further includes a locking device separate from the at least one pressure spring. The locking device fixes the piston in a neutral position relative to the housing below a predetermined unlocking force exerted on the piston or the housing.
Claims13
A motorcycle transmission shifting assistance device, comprising:
- a housing;
- a piston displaceably arranged in the housing;
- at least one compression spring arranged in the housing such that when compressed at least one of the at least one compression spring presses on the piston, and
- a locking device configured to fix the piston in a neutral position relative to the housing when an axial displacement force exerted on at least one of the piston and the housing is below a predefined unlocking force.
A shifting device for a motorcycle, comprising:
- a shifting lever configured to be actuated in a first shifting direction and in a second shifting direction opposite the first shifting direction;
- and
- a transmission shifting assistance device configured to couple the shifting lever to a shifting input of a motorcycle transmission, the transmission shifting assistance device including
- a housing;
- a piston displaceably arranged in the housing;
- at least one compression spring arranged in the housing such that when compressed at least one of the at least one compression spring presses on the piston, and
- a locking device configured to fix the piston in a neutral position relative to the housing when an axial displacement force exerted on at least one of the piston and the housing is below a predefined unlocking force.
