Claims

[Scope of utility model registration request]

An input shaft, a first intermediate shaft, a second intermediate shaft, and an output shaft are arranged concentrically with each other and rotatably supported on a transmission case, and the input shaft is rotatably supported on a carrier between a sun gear and a ring gear. It is equipped with two simple planetary gear sets, first and second, in which the supported pinion gears are meshed to form a set, each of which has the axis of the input shaft as the center of rotation or revolution, and further includes three sets of simple planetary gears, first to third. The sun gear of the first simple planetary gear set is coupled to the first intermediate shaft, and the carrier of the first simple planetary gear set and the second The ring gear of the simple planetary gear set and the output shaft are coupled, the ring gear of the first simple planetary gear set, the carrier of the second simple planetary gear set, and the second intermediate shaft are coupled, and the first clutch device is coupled to the input shaft. A second clutch device is arranged to connect the input shaft and the second intermediate shaft, and a third clutch device connects the input shaft and the second simple planetary gear set. The first brake device is arranged to be able to prevent the rotation of the first intermediate shaft, and the second brake device is arranged to prevent the rotation of the ring gear of the first simple planetary gear set and the second The third brake device is arranged so as to be able to prevent the rotation of the carrier of the simple planetary gear set and the rotation of the second intermediate shaft, and the third brake device is arranged so as to be able to prevent the rotation of the sun gear of the second simple planetary gear set. Gear transmission.
