Filed: 1988-12-13
Abstract: PURPOSE:To make it possible to decrease the torque load on the belt and to transmit greater torque by combining a belt type speed change mechanism, a planetary gear train mechanism, and a fluid torque converter together. CONSTITUTION:When the engine revolution is gradually increased from the time of low engine rpm such as at the start of an automobile, a belt type speed change mechanism 2 gradually changes to a higher speed side and causes a ring gear 13 to rotate at a higher revolution ratio. A planetary gear 14 then revolves accordingly at a higher revolution ratio.

As a result, an overall speed change range is obtained which is the product of the speed change range with the belt type transmission mechanism and the speed change range with a torque converter mechanism. A clutch 25 is provided for reducing the load at the time of start or idling of the engine. Torque is transmitted up to the input shaft of a fluid torque converter even in the case without a clutch.
