Abstract
A transmission has a directional mechanism, a planetary gear mechanism, a stepped transmission and a continuously variable ratio device. The directional mechanism has at least one direction clutch. The planetary gear mechanism is connected to the direction mechanism and has at first planetary gear set and a second planetary gear set. The stepped transmission is connected to the planetary gear mechanism and has at least one speed clutch. The planetary gear mechanism is connected to a hydrostatic motor of the continuously variable ratio device. The motor is connected to a variable displacement pump of the continuously variable ratio device.
