Title:
車両用トランスミッション
Document Type and Number:
Japanese Patent JP4346059
Kind Code:
B2
Abstract:
A transmission for a vehicle having a sub shaft supported in casings via bearings (20,69), and an input gear (34), an output gear (46), and a boss of a clutch outer, etc. stacked on the sub shaft and retained by a cotter key. The input gear and the output gear are helical gears, and thrust forces (F1,F2) acting on the two gears are generated in opposite directions. A rightward thrust force acting on the input gear is borne by the casing via an annular projection (61), the sub shaft and the bearing (20), and a leftward force acting on the output gear, which is separated from the cotter key by a gap, is borne by the casing via the bearing (69) provided on the side face of the output gear. This arrangement eliminates any need for fixing gears supported on a shaft of a transmission by a nut or a bolt in the axial direction, thus saving space and reducing the number of parts.
