Abstract
A clutch assembly for a transmission having a gear radially supported relative to a shaft in which the clutch assembly includes a clutch plate rotationally coupled to the shaft. The clutch plate further includes an engaged state whereby a surface of the clutch plate abuts a surface of the gear to rotationally couple the gear to the shaft and a disengaged state whereby the clutch surface is spaced from the gear surface to rotationally uncouple the gear and the clutch plate. A transmission assembly includes a first shaft, a second shaft, and a plurality of gears interconnecting the first shaft and the second shaft such that each gear of the plurality of gears is radially supported by one of the first and second shafts. The transmission assembly can further include a plurality of the clutch assemblies.
Claims19
A clutch assembly for a transmission having a gear radially supported relative to a shaft, the clutch assembly comprising:
- a clutch plate rotationally coupled to the shaft, wherein the clutch plate has an engaged state whereby a surface of the clutch plate abuts a surface of the gear to rotationally couple the gear to the shaft and a disengaged state whereby the clutch surface is spaced from the gear surface to rotationally uncouple the gear and the clutch plate.
A transmission comprising:
- a first shaft driven by an engine;
- a second shaft;
- a plurality of gears interconnecting the first shaft and the second shaft, wherein each gear of the plurality of gears is radially supported by one of the first and second shafts;
- and
- a plurality of clutch assemblies, each clutch assembly comprising:
- a clutch plate rotationally coupled to one of the first and second shafts, wherein the clutch plate has an engaged state whereby a surface of the clutch plate abuts a mating surface of one of the plurality of gears to rotationally couple the one of the plurality of gears to one of the first and second shafts and a disengaged state whereby the clutch surface is spaced from the mating surface to rotationally uncouple the one of the plurality of gears and the clutch plate.
