Abstract

The present invention provides a vehicle that can achieve miniaturization in the front-rear direction of the vehicle. A vehicle (10) includes an engine (19), a generator (20), and a motor (22). The engine (19) burns a gaseous mixture in a cylinder to output a drive force. The generator (20) generates electricity by being rotated by the drive force outputted from the engine (19). The motor (22) drives by utilizing electric power (20) generated by the generator or electric power that has accumulated in a battery charged with electric power generated by the generator, and the motor (20) thereby outputs a vehicle-running drive force. A case (61) covering the motor (22) is of larger diameter than a case (65) covering a differential. The motor (22) has an output shaft outputting the vehicle-running drive force, and has the output shaft disposed parallel to a vehicle width direction. The generator (20) is disposed such that part of the generator overlaps an upper section (65a) of the case covering the differential.

Description

technical field

[0001] The present invention relates to a vehicle that travels using a driving force output from an electric motor driven using electric power generated using a driving force output from an engine or stored in a battery. Background technique

[0002] Conventionally, a hybrid vehicle of a series type (in-line type) is known. In this hybrid vehicle, an engine drives a generator motor, the generated electric power is stored in a high-voltage battery, and the electric power is used to drive the motor. It is driven and travels using only a drive motor as a drive source (for example, refer to Patent Document 1). In the hybrid vehicle described in Patent Document 1, the engine and the generator motor constituting the power generation unit are arranged close to each other in a state where the crankshaft and the rotation shaft of the generator motor are connected on the same axis. Furthermore, the crankshaft of the power generating unit is arranged in a direction per...
