ABSTRACT:
A transmission having an input shaft with a sun gear (12), a medium speed shaft with a sun gear (14) rotatably mounted on the input shaft, a low speed shaft with a sun gear (16) rotatable mounted on the medium speed shaft and a reverse rotation shaft with a sun gear (18) rotatable mounted on the low speed shaft. A first carrier and a second carrier terminating in an output shaft are rotatably mounted on the reverse shaft and input shaft, respectively. Locking pins interconnect first and second carriers. Reverse rotation gear is integrally formed with an input gear and rotatable mounted on a locking pin. Each reverse rotation gear meshes with the reverse sun gear (18) and each input gear meshes with sun gear (12). Low speed gears are integrally formed with a medium speed gear and rotatable mounted on a locking pin. Each low speed gear meshes with sun gear (16) and each medium speed gear meshes with the input gear and the sun gear (14). Low speed brake (41) brakes the low speed shaft to provide a low speed rotation of the output shaft. Medium speed brake (42) brakes the medium speed shaft to provide a medium speed rotation of the output shaft. Interlocking system (50) directly couples the input shaft and the medium speed shaft to provide high speed rotation of the output shaft. Reverse rotation brake (43) brakes the reverse rotation shaft to provide reverse rotation of the output shaft.
