Power plant for hybrid motor vehicle

摘要

A hybrid vehicle power unit includes an engine, a generator and a traction motor. A mounting bracket includes a base portion and a plurality of junctions arranged along the outer edge of an end of the generator at a plurality of points spaced at interval to fasten the base portion to the end. Dividing the end by an imaginary vertical plane that includes a rotor axis of the generator into a front area and a rear area with respect to the longitudinal axis of the vehicle, the number of some of the plurality of junctions located in the rear area is larger than the number of the remainder of the plurality of junctions located in the front area. A generator mount between an end portion of the mounting bracket and a side member is arranged in front of the imaginary vertical plane with respect to the longitudinal axis.

1. A power unit for a hybrid vehicle, the hybrid vehicle including a vehicle body having an engine compartment, and a pair of side members spaced in a transverse direction toward both sides of the vehicle within the engine compartment and extending along a longitudinal axis of the vehicle,
the power unit comprising: an engine having a crankshaft with the crankshaft axis oriented along the transverse direction of the vehicle; a generator connected to one end of the engine with respect to the crankshaft axis; a traction motor, located in the rear of the generator with respect to the longitudinal axis of the vehicle, connected to the generator in a direction along a line that meets the crankshaft axis at right angles; a mounting bracket protruding from that one end of the generator's axially spaced, along the transverse direction of the vehicle, ends which is not adjacent the engine, the mounting bracket having a base portion in contact with the end of the generator, the base portion of the mounting bracket having an outline extending along an outer edge of the end of the generator and a plurality of junctions arranged along the outer edge of the end at a plurality of points spaced at interval to fasten the base portion to the end of the generator, the plurality of junctions being arranged such that dividing the end of the generator by an imaginary vertical plane that includes a rotor axis of the generator into a front area and a rear area with respect to the longitudinal axis of the vehicle, the number of some of the plurality of junctions located in the rear area is larger than the number of the remainder of the plurality of junctions located in the front area; and a generator mount between an end portion of the mounting bracket and one of the pair of side members and arranged in front of the imaginary vertical plane with respect to the longitudinal axis of the vehicle.
