Abstract:
A compact creeper gear arrangement (70) for a multiple speed transmission (12) in which the creeper gear input (78) and output shafts (88) are laterally spaced from and parallel to the major shafts within the transmission. The creeper gear arrangement (70) utilizes an input gear (74) integral with one of the speed range gears (72) and selectively coupled to a shaft (24) that provides an input to a mechanical front wheel drive assembly (41). The creeper gear arrangement (70) is a dual speed selectively engageable transmission where much of the mechanism is located within otherwise unused space within the transmission.
