CHAIN DRIVEN REVERSE GEAR FOR A MANUAL TRANSMISSION

摘要

A fifth forward speed pinion is mounted by a bearing on the end of a countershaft that provides a space into which the bearing is fitted. A roller bearing mounted in the transmission casing supports the fifth speed pinion at the opposite end from that of the countershaft. The countershaft carries a reverse drive sprocket that is selectively connected to the countershaft by movement of a synchronizer clutch in accordance with control exercised by the vehicle operator. A reverse driven sprocket is drivably connected to the output shaft and torque is transmitted between the sprockets by a flexible, endless chain or belt.
