Assignee:

Cooper Industries, Inc. - Houston TX

International Classification:

F16H 308
F16H 5704
F16H 5702

US Classification:

74360

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.

Abstract:

A multispeed constant mesh gear transmission includes an input shaft together with first, second and third intermediate shafts arranged in a diamond or cruciform configuration together with an output shaft having an axis of rotation lying in a plane including the input shaft and the third intermediate shaft. In two different embodiments each of the three intermediate shafts include two multiplate fluid actuatable clutches shiftable under load. A plurality of gear trains selectively drive an output shaft at six different rotative speed ratios with respect to the input shaft in one direction of rotation of the output shaft and at three different speed ratios in the opposite or reverse direction of rotation of the output shaft. In one embodiment a total of six clutches and fourteen gears provide for the speed ratios and in a second embodiment a total of twelve gears and six clutches provide for the six forward and three reverse speed ratios.
