Stufenloses Getriebe mit Keilriemen

摘要

A belt continuously variable transmission apparatus having a case which includes a power transmission case (40) (which is part of a crankcase of an engine), a power transmission case cover (401), and an actuator cover (58) assembled forwardly of the power transmission case cover (401) (displaced forwardly on a vehicle body). The actuator cover (58) is formed as a separate member from the power transmission case cover (401), and supports a motor (57) for driving a movable part (452) of a driving pulley (45). In addition, the actuator cover (58) covers a gear system (60). The actuator cover (58) is integrated with a cover of the water pump. The resulting configuration improves the assembling of the actuator cover (58) of the belt continuously variable transmission apparatus.
