Abstract
In a pump system for a hybrid electric transmission, the pump is alternately driven by the input shaft and the output shaft, whichever is rotating faster. The input shaft and output shaft are co-axial. Sprockets and a chain transmit power from axis of the input and output shafts to the axis of the pump. The driven sprocket is selectively coupled to the input shaft by a first one-way-clutch and selectively coupled to the output shaft by a second one-way-clutch. Two alternative one-way-clutch and bearing arrangement are disclosed.
