摘要

A continuously variable automotive transmission includes a fluid torque converter (2) adapted to be connected to an engine (1) and having a turbine shaft (6), a single driver gear (21;Fig.1) or two driver gears (21,22;Fig.2) fixedly mounted on the turbine shaft, and a V-belt continuously variable transmission mechanism (10). The V-belt continuously variable transmission mechanism comprises a driver pulley (13) mounted on a driver shaft (11) parallel to the turbine shaft, a driven pulley (16) mounted on a driven shaft (12) parallel to the turbine shaft, a V belt (19) trained around the driver and driven pulleys, a forward gear (23) rotatably mounted on the driver shaft (11) and held in mesh with the single driver gear (21) on one of the two driver gears, a forward clutch (24) mounted on the driver shaft for selectively connecting and disconnecting the forward gear to and from the driver shaft, a reverse gear (26) rotatably mounted on the driven shaft (12) and held in mesh with the single driver gear (21) or the other of the two driver gears through an idler gear (25), and a reverse clutch (27) mounted on the driven shaft for selectively connecting and disconnecting the reverse gear to and from the driven shaft.
