Lubrication structure for hybrid type vehicle power unit
Abstract:
In a hybrid type vehicle power unit including a first oil pump interlockingly connected to a crankshaft so as to supply at least a lubricating oil to an engine and a transmission, and a second oil pump for supplying the lubricating oil to the transmission, it is not necessary for an electric motor to be exclusively used for the second oil pump. Thus, a reduction in the number of component parts and a reduction in the cost of manufacturing are achieved. The second oil pump is interlockingly connected to an electric motor capable of transmitting a driving torque to an output shaft through the transmission.
