Abstract
A multi-speed power shift gear transmission includes an input shaft, an output shaft and two clutch shafts arranged substantially parallel to each other. Each of the clutch shafts includes a directional clutch and two speed range clutches whereby a total of four speeds in each direction of rotation of the output shaft may be obtained. The clutch shafts are arranged to support the directional clutches at adjacent ends whereby the directional clutches may be accessed for service and repair by removal of a separate cover member and without removing any of the other clutches or gears from the clutch shafts. The opposite ends of the clutch shafts are adapted to support and locate a control valve housing for close communication of the clutch actuating fluid control valves and the transmission cooling and lubricant fluid flow paths.
