Abstract: A pulley mechanism of a vehicular belt-type continuously variable transmission that makes it possible to enhance the joint strength between a rotary shaft and a stationary sheave without increasing the axial length of the belt-type continuously variable transmission is provided. Since a first stationary portion and a second stationary portion are provided on both sides of a step portion respectively, a stationary sheave is fixed by this first stationary portion and this second stationary portion, and the joint strength between the stationary sheave and an output shaft increases. Besides, a belt reaction force during power transmission can be received by the first stationary portion and the second stationary portion. Therefore, the amount of inclination of the stationary sheave during power transmission is also held small, and a fall in the torque capacity and transmission efficiency of the belt-type continuously variable transmission and a deterioration in the NV characteristics of the belt-type continuously variable transmission can be suppressed.

Abstract: In a vehicular belt-driven continuously variable transmission, belt squeezing force is inhibited from becoming excessive and a safety factor, with respect to belt slip, of belt squeezing force applied to a transmission belt (48) is reduced to a value that is less than or equal to 1.5 by reducing a pressure receiving area (SOUT) of an output side hydraulic cylinder (46c). As a result, a centrifugal hydraulic pressure canceller chamber on a secondary pulley side (46) can be eliminated thus simplifying the structure of the vehicular belt-driven continuously variable transmission, while belt squeezing force can be appropriately controlled.

A fifth gear and a sixth gear disposed on the general output shaft are respectively meshed with the third gear and the fourth gear which are connected to the second clutch output shaft and selectively connected to the general output shaft with a first synchronizing device disposed on the general output shaft, and interlock the second clutch output shaft and the general output shaft in association with the third gear and the fourth gear. A seventh gear meshed with the fifth gear and a eighth gear meshed with the fourth gear disposed on the sub shaft interlock the sub shaft and the general output shaft by selectively connecting the seventh gear and the eighth gear themselves to the sub shaft by the second synchronizing device so as to complete the first forward speed gearing in addition to completing the reverse gearing.
