Abstract

PURPOSE: To obtain the built-in costruction of a torque converter to a transmission without largely modifying its casing from a conventional transmission, by providing a friction clutch between the torque converter and a drive gear and releasing the friction clutch when a speed shift of the transmission is operated.
CONSTITUTION: A gear transmission 1 of a motor cycle is constructed in such a manner that drive gears 2, 2 and driven gears 3, 3 are arranged parallelly to a crankshaft 4 of an engine. In a casing 5 of said gear transmission 1, an input shaft 6 interruptably connected to the two drive gears 2 through a multiple disc friction clutch 8 and an output shaft 7 locked to one of the driven gears 3 through a clutch 18 are parallelly supported to each other. To said input shaft 6 a fluidic torque converter 25 is mounted on the outer surface of the casing 5. Then a revolution of the crankshaft 4 is transmitted to the input shaft 6 through a primary reduction gear train G1 and the torque converter 25, and transmitted to the output shaft 7 through the drive gears 2, 2 and driven gears 3, 3 when the clutch 8 is engaged.
