Embodiment Construction

[0038] image 3 The structure of the power transmission system 200 according to the embodiment of the present invention is illustrated by a block diagram. The powertrain 200 is used in a hybrid electric vehicle (not shown). It is also conceivable that the powertrain could be applied, or adapted, to a variety of hybrid vehicles of different sizes and applications, and in this embodiment the vehicle is an approximately 7.5 ton enclosed van or truck. This vehicle is an industrial vehicle that is often used to transport large quantities of goods.

[0039] continue to refer image 3 , the powertrain 200 includes a diesel engine 210 , a first axial flux motor 220 , an internal gear 225 , a second axial flux motor 230 , a conventional clutch 240 , a conventional gearbox 250 , a drive shaft 260 and wheels 270 .

[0040] The first axial flux motor 220 is arranged on the engine 210, the rotor of the motor 220 is connected with the crankshaft of the motor 210, and rotates relative to ...

Abstract

A drivetrain for a hybrid-electric vehicle (200), including an engine (210), a first electrical machine (220), a second electrical machine (230), and at least one driveshaft (260). The first (220) and second (230) electrical machines are axial-flux electrical machines. The first electrical machine (220) is arranged to be driven by the engine (210) so as to operate as a generator and to supply electrical power for the second electrical machine (230). The second electrical machine (230) is arranged to receive electrical power so as to operate as a motor and to drive the at least one driveshaft (260). The drivetrain includes a clutch (225) selectively operable to provide inter- engagement between the rotor of the first electrical machine (220) and the rotor of the second electrical machine (230) to transmit rotary power therebetween.

Description

technical field [0001] The present invention relates to a power transmission system for a hybrid electric vehicle. Background technique [0002] Hybrid electric vehicles, which are becoming more popular, include both an internal combustion engine and an electric machine that act like electric motors to at least help drive the car's wheels. That's at least partly due to their vastly improved fuel efficiency. A car's drivetrain is the combination of components that turn power into propelling the car, usually in several configurations. Two existing configurations of a power transmission system for a hybrid electric vehicle are: a serial power transmission system configuration and a parallel configuration. [0003] figure 1 The serial drivetrain configuration 10 is illustrated in a simple block diagram. refer to figure 1 The engine 20 is mechanically connected to the first motor 30 to drive the rotor of the first motor to rotate, so that the first motor 30 works as a genera...
