A vehicle drive system includes a motor (drive motor), a generator, a reduction drive that reduces output of the motor, and a housing. At a position above a motor shaft, an oil passage, through which oil is supplied to each of the motor, the reduction drive, and the generator, is integrally formed with the housing. An oil pipe is attached to the housing and supplies the oil from an oil reservoir to the oil passage. At a position between the motor and the generator, the reduction drive is offset from the motor shaft in a second direction that is orthogonal to the first direction. The oil pipe is located between the motor and the generator in the first direction, and at least part of the oil pipe is located on an opposite side of the reduction drive with the motor shaft being interposed therebetween in the second direction.

Vehicle drive system

A vehicle driving apparatus is provided that includes a drive motor, an internal combustion engine, and an electrical generator and can inhibit a weight balance and motion performance of a vehicle from being deteriorated and lowered. A vehicle driving apparatus driving a vehicle by motive power of a motor, the vehicle driving apparatus including a drive motor that is driven by electric power, an internal combustion engine that produces motive power by fuel, and an electrical generator that is driven by the internal combustion engine, the vehicle driving apparatus being characterized in that the drive motor, the internal combustion engine, and the electrical generator are arranged in a vehicle width direction of the vehicle in order of the drive motor, the internal combustion engine, and the electrical generator.

Vehicle driving apparatus

In an engine compartment, an engine, a generator using the engine as a power source, a motor for driving the vehicle, and a gear box are arranged in alignment in a vehicle width direction. The first high-voltage equipment is vertically provided on a generating unit that includes the engine and the generator. The second high-voltage equipment is vertically provided on a drive unit that includes the motor and the gear box. The first high-voltage equipment and the second high-voltage equipment are coupled by a coupling member that extends substantially horizontally in the vehicle width direction and supports the high-voltage equipment, against a falling load directed from one thereof toward the other.

In-vehicle structure of electrical equipment

A power train support structure includes a first front side frame disposed on one of left and right sides of a power train; a second front side frame disposed on the other of the left and right sides of the power train, and being greatly away from the power train with respect to the first front side frame; a mounting bracket having one of left and right ends connected to the power train; and a connecting member for connecting the mounting bracket and the second front side frame. The mounting bracket includes a front fixing portion and a rear fixing portion to be fixed to the power train. A strength of the front fixing portion and the rear fixing portion is set to such a strength that the rear fixing portion is broken by a collision load from a front side, and the front fixing portion is not broken.

Power train support structure for vehicle

At least one of a pair of right and left motor unit support systems for mounting and supporting a motor unit () on a cross member () is fastened and fixed to an upper part of the motor unit () by a first shaft-like fastening member (a first bolt ()). An axial direction of the first shaft-like fastening member (the first bolt ()) is the same as a vehicle longitudinal direction in a state in which the at least one of the motor unit support systems is fastened and fixed to the upper part of the motor unit ().

Electric vehicle

An electric-drive vehicle structure is provided, which includes a cross member bridged between side frames in a front part of a vehicle, a motor suspended below the cross member, a tray fixed to an upper surface of the cross member, and an electric unit for driving a motor, fixed onto the tray. A front edge of the electric unit is located forward of a front edge of the cross member, and the tray has a front edge located, throughout a width thereof, forward of the electric unit.
