Abstract
A transmission for vehicles is composed of an input shaft provided with a plurality of drive gears and connected to a drive shaft of an engine, an output shaft disposed parallel to the input shaft, driven gears which mesh with the drive gears, individually, and are rotatably disposed on the output shaft, a synchromesh mechanism which includes a sleeve axially movable relative to the output shaft and engages with a side of the driven gears, thereby connecting the driven gears to the output shaft, and a parking gear formed integrally on a hub of the synchromesh mechanism, the parking gear radially overlapping a bearing from outside. Thus, there may be provided a transmission for vehicles that requires less component parts and has a small transverse dimension.
Claims12
A transmission for vehicles, comprising:
- an input shaft to which a driving force is input from an engine;
- a drive gear which is fixed to the input shaft and rotates together with the input shaft;
- an output shaft disposed parallel to the input shaft;
- a driven gear which meshes with the drive gear and is rotatably disposed on the output shaft;
- a hub which is fixed to the output shaft so as to adjoin the driven gear on an end side of the output shaft and rotates together with the output shaft;
- and
- a sleeve which is located around the hub so as to be continuously rotatable together with the hub and axially slidable and moves in an opposite direction to the end of the output shaft so that the driven gear is drivingly connected to the output shaft,
- a bearing of the output shaft being composed of a first bearing in vicinity of an arrangement side of the engine and a second bearing arrange at a position remote from the engine farther than the first bearing, an outer peripheral end of the hub extending toward the shaft end so that a parking gear is formed integrally on an extending end, and the parking gear and the second bearing being axially superposed on each other.
