Vehicle gear shifter

摘要

A vehicle transmission includes for an electric drive vehicle a clutch for selectively drivingly connecting an input shaft and an output shaft through a gear set. A clutch collar rotationally drives one or more axially aligned rows of at least two and preferably three drive members, such as ball bearings. The clutch collar is movable between drive position in which the input shaft and output shaft are drivingly engaged through two drive members, a park position in which one drive member is rotationally fixed to the housing, and a tow position in which the drive members are disengaged from the input shaft.

主权项

1. A transmission comprising:
a housing, an input shaft rotatable about an axis, an output shaft, a gear set, and a rotatable clutch assembly coaxial with the input shaft for selectively drivingly connecting the input shaft and the output shaft through the gear set, the clutch assembly comprising a clutch collar and two axially spaced drive members, each drive member separate from the clutch collar and rotationally drivingly connected to the clutch collar, the clutch collar axially movable between (a) a drive position in which the input shaft is drivingly engaged with one drive member and the output shaft is drivingly engaged with the input shaft through the other drive member and the gear set, (b) a park position in which the gear set is drivingly engaged with one drive member and the other drive member is rotationally fixed to the housing, and (c) a neutral position in which the two drive members are disengaged from the input shaft.
