摘要： A gearbox oil cooling assembly for a gearbox driving a drive shaft having a drive shaft coupling. The assembly includes a heat exchanger to receive and cool an oil from the gearbox and having an inlet. Also included is an impeller axially disposed between the heat exchanger and the drive shaft coupling, wherein the impeller is operatively coupled to, and rotated by, the drive shaft operatively coupled to the drive shaft coupling. Further included is an exhaust duct operatively coupled to the heat exchanger and disposed radially outwardly around the impeller and defining an airflow pathway through which air passes through the inlet, the impeller and through the exhaust duct according to the rotation of the impeller to cool the oil in the heat exchanger.

摘要： A multi-plate clutch apparatus is provided and includes a multi-plate clutch disposed to occupy clutch and non-clutch positions at which rotation of an input shaft is and is not transmitted to an output shaft, respectively, a drive element disposed about the multi-plate clutch and configured to generate rotational energy and a linear actuator disposed to convert the rotational energy of the drive element to linear movement by which the multi-plate clutch is controllable to occupy one of the clutch and non-clutch positions.
