Benefits of technology

By providing a speed increasing gear assembly inside of the rotor, the generator offers the advantages of shortening the axial length and allowing generation of an effectively higher voltage by the generator.
Locating the transmission

Problems solved by technology

In the series type hybrid vehicle, such a disadvantage is conspicuous due to a relatively large generator, so that an arrangement aligning the internal combustion engine, generator, electric motor and transmission all together in an engine compartment at the front of the vehicle is impossible.
Even if such an arrangement could be fit into the e

Embodiment Construction

A first preferred embodiment of the present invention will now be described with reference to FIGS. 1 and 2.

An engine compartment provided at a front portion of the vehicle houses an internal combustion engine (hereinafter referred to as "engine") 1, such as a gasoline or diesel engine, which is transversely mounted, and a hybrid unit 2, which replaces a conventional automatic-transmission unit and receives output of the engine 1. The hybrid unit 2 has an integral case 3 which abuts one end of the engine and is defined by three sections (3A, 3B, 3C). Case 3 houses a generator 6, a clutch 7, a two-speed automatic transmission unit 9 and an electric motor in alignment with output shaft la of the engine 1. A differential gear unit 11 is mounted under the case 3.

The generator 6 is provided, in place of the torque converter of the conventional automatic transmission unit, adjacent to the engine 1 in a generator housing 3A forming one section of the integral case 3. The generator 6 has a ...

Abstract

A hybrid vehicle having an internal combustion engine, a generator connected with an output shaft extending from the internal combustion engine, an electric motor axially aligned with the output shaft, an output gear assembly connected to an output shaft driven by the rotor of the electric motor and positioned between the generator and the electric motor, a clutch adapted to connect and disconnect the generator to/from the output gear assembly, a differential gear unit, and a counter shaft oriented in parallel the output shaft driven by the rotor.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThis invention relates to a vehicle having a hybrid power source operationally combining an internal combustion engine, such as a gasoline engine, diesel engine or gas-turbine engine, with an electric motor operating off current stored in a battery mounted in the vehicle and, more particularly, to an assembly including the internal combustion engine, a generator and the electric motor in a hybrid vehicle.2. Description of the Related ArtThe present invention can be applied both to a series type assembly and a parallel type assembly. Three types of hybrid arrangement are known. The first type is the series type assembly in which the hybrid vehicle moves under power of the electric motor operating on current generated by the generator driven by the internal combustion engine which is constantly running. The second type is the parallel type assembly in which both the internal combustion engine and the electric motor are arranged to re...
