ABSTRACT:
A variable speed transmission (1) is disclosed which has a torque converter (6) at the input of both a fixed transmission (4) which is used for low vehicle speeds and a variable transmission (5) which is used for medium and high vehicle speeds. The variable transmission (5) has a variator (11) which may be of the belt and pulley, hydraulic or electric types. The variable transmission (5) is more efficient than heretofore because power is split within the variable transmission (5) by a power split differential (9) between the variator (11) and a main power output shaft (3). Thus, the variator (11) is only called upon to handle a portion of the power when the variable transmission (5) is in operation. Thus, power losses in the variator (11) are substantially reduced.
