A modular assembly is described for a power train. An assembly housing includes first and second cavities connected by an inter-cavity passage. An input shaft and an output shaft linked by a first clutch are disposed, at least in part, in the first cavity. A hydraulic control assembly provides hydraulic control signals to control, at least in part, the first clutch device. A hydraulic quill insert disposed, at least in part, in the inter-cavity passage, includes a plurality of control passages. The hydraulic quill insert receives the hydraulic control signals and directs the signals to control power flow from the input shaft to the output shaft. |

1. A modular power-train assembly comprising:
an assembly housing having first and second cavities, the first and second cavities being connected by an inter-cavity passage; an input shaft disposed, at least in part, within the first cavity of the housing, the input shaft including a first gear and receiving rotational power from a power source; an output shaft disposed, at least in part, within the first cavity of the housing; a first clutch device providing a controllable power-transmission link between the input shaft and the output shaft; a hydraulic control assembly providing hydraulic control signals to control, at least in part, power flow from the input shaft to the output shaft; and a hydraulic routing system receiving hydraulic control signals from the hydraulic control assembly and directing the received hydraulic control signals to control, at least in part, power flow from the input shaft to the output shaft; wherein a high-low power-reverser countershaft with second and third clutch devices includes a first geared connection to the first gear of the input shaft, a second geared connection to the output shaft via the second clutch device, and a third geared connection to the output shaft via the third clutch device and a first idler gear; wherein a high-low countershaft with a fourth clutch device includes a fourth geared connection to the first gear of the input shaft, and a fifth geared connection to the output shaft via the fourth clutch device; wherein a power-reverser countershaft with a fifth clutch device includes a sixth geared connection to the first gear of the input shaft, and a seventh geared connection to the output shaft via the fifth clutch device and a second idler gear; wherein the assembly housing is configured to separately receive, without modification of the assembly housing, each of the high-low power-reverser countershaft, the high-low countershaft, and the power-reverser shaft; and wherein the hydraulic routing system separately directs the received hydraulic control signals, respectively, to at least one of the second and third clutch devices, to the fourth clutch device, or to the fifth clutch device, depending on whether the high-low power-reverser countershaft, the high-low countershaft, or the power-reverser countershaft is currently received by the assembly housing. |
