Abstract
The transmission includes a rotation shaft, a shift gear, and a gear switching part. The shift gear is rotatably supported by the rotation shaft. The gear switching part is relatively unrotatably supported by the rotation shaft in a movable manner in an axial direction. The gear switching part is configured to be moved in the axial direction by a shift fork, to switch connection and disconnection between the rotation shaft and the shift gear. The gear switching part and the shift fork have a bearing therebetween. The bearing is brought into contact with the gear switching part and the shift fork, thereby reducing friction between the gear switching part and the shift fork, resulting in improvement of durability of the sliding surfaces of the gear switching part and the shift fork.
Claims15
A transmission comprising:
- a rotation shaft;
- a shift gear rotatably supported by the rotation shaft;
- and
- a gear switching part relatively unrotatably supported by the rotation shaft in a movable manner in an axial direction, the gear switching part configured to be moved in the axial direction by a shift fork to switch connection and disconnection between the rotation shaft and the shift gear,
- wherein a bearing is disposed between the shift fork and the gear switching part in contact with the shift fork and the gear switching part, the bearing comprising:
- a first inner bearing member and a first outer bearing member disposed in rotatable relation between the shift fork and the gear switching part on a first side of the shift fork, and
- a second inner bearing member and a second outer bearing member disposed in rotatable relation between the shift fork and the gear switching part on a second side of the shift fork,
- wherein the first and second inner bearing members comprise washers, and wherein the first and second outer bearing members comprise washers.
