TRANSMISSION
First Claim
1. A transmission, comprising:
- an upstream side transmission mechanism that transforms the rotation of an upstream side input member that rotates by receiving input rotation into N steps, and transmits the transformed rotation to an upstream side output member; and
a compound planet gear transmission mechanism having two or more planet gear trains, that transforms the rotation of the upstream side output member and outputs the transformed rotation to an output shaft of the transmission,wherein of first through fourth rotating elements constituting the compound planet gear transmission mechanism,the first rotating element can be freely engaged with or disengaged from the upstream side input member via first clutch means;
the second rotating element is connected to the output shaft of the transmission;
the third rotating element can be freely engaged with or disengaged from the upstream side input member via second clutch means, and can be held fixed by second brake means; and
the fourth rotating element can be held fixed by first brake means, and is connected to the upstream side output member.

Abstract
The present invention includes an input side transmission unit that transforms the rotation of the input shaft that rotates by receiving input rotation into N steps, and transmits the transformed rotation to the counter shaft; and an output side transmission unit that includes a first planet gear train and a second planet gear train, and that transforms the rotation of the counter shaft and outputs the transformed rotation to the output shaft. Of the first through fourth rotating elements constituting the output side transmission unit, the first and second sun gears are connected so that they can be freely engaged with or disengaged from the input shaft via the first clutch; the first carrier is connected to the output shaft; the second carrier and the first ring gear are connected so that they can be freely engaged with or disengaged from the input shaft via the second clutch and can be held fixed by the second brake; and the second ring gear can be held fixed by the first brake, and is connected to the upstream side output member.
