Abstract
The utility model relates to a rear transaxle with a reverse gear for a three-wheeled motorcycle. The rear transaxle consists essentially of a main decelerator, a transaxle housing and a semi-axis. The flange of a universal joint of the main decelerator is connected with the drive shaft through a screw, transmitting the power. One side of the semi-axis is connected with the semi-axis gear. The braking chassis limits the semi-axis at the same time. The other side of the semi-axis is extended outwards from the transaxle housing. The transaxle housing is provided with a felt washer and a protective cover of the felt washer at both sides. The gear in the cavity in front of the main decelerator is arranged longitudinally and connected with the pressed and welded steel plate transaxle housing. The product has the advantages of compact structure, high transmission efficiency, long service life, and good lubricating performance of the movement components and fewer contact surfaces of the overall transaxle, which has the handover function between the deceleration, differential speed, forwarding and reversing gears.
