is the fifth speed gear thus as mentioned above in the illustrated embodiment of the automated gear transmission 10 according to the invention the gear wheel 23 mounted on the solid first input shaft 11 for engagement with the ring gear 22 of the planetary gear set 21 is an idler gear which serves to transmit torque for the reverse speed moreover in the illustrated embodiment the gear wheel 20 is secured to input shaft 12 for engagement with the gear wheel 19 on the auxiliary shaft 18 the gear wheel 23 is secured to input shaft 11 for engagement with the ring gear 22 and is designed as a fixed gear although when clutch 14 of the solid input shaft is disengaged the fixed type third speed gear 23 becomes an idler gear shifting into reverse is achieved via the planet carrier 24 of the planetary gear set 21 by bringing planet carrier 24 into form fitting non slip engagement with the housing 25 which is fixed against rotation thus through the stationary planet carrier 24 of the planetary gear set 21 a reversal of the rotational direction of the auxiliary shaft 18 is achieved in a known manner via the sun gear 30 and the fixed planet gears 31 which turning against the direction of the sun gear 30 act on the ring gear 22 reference is made here in particular to fig2 which shows the directions of rotation of the gears relevant for transmission of the reverse speed with u201c l u201d denoting the counterclockwise direction and u201c r u201d the clockwise direction viewed from the input toward the clutch when the reverse speed.
