Distributed differential coupling combined power system

Abstract

A combined power system includes a rotational power source such as an internal combustion engine, the output shaft of which is arranged to drive a front section load and which is also coupled to the input shaft of an electromagnetic coupling device to drive a rear section load. The electromagnetic coupling device is controlled by an operating device to generate motor driving functions, when an input current is applied or to generate variable speed coupling functions through an output current when the electromagnetic coupling device is employed as a generator. The engine can be operated at constant speed or at a partially adjustable speed to maximize engine efficiency and reduce pollution, with one part of the differential speed output power generated throughout the differential mixing drive device being used for driving the load while the remainder of the power is converted through the generator function of the electromagnetic coupling device to charge the battery and thereby increase energy efficiency.

Description

BACKGROUND OF THE INVENTION

[0001] In recent years, energy and noise pollution problems have become more and more serious. A good solution to these problems would be to use electrical power driven vehicles, but development of electrical power driven vehicles has up to now been limited by the capacity of the batteries to achieve a larger moving range. Increasing the battery volume or quantity to increase the range will correspondingly increase the self-weight of the carrier, resulting in higher electrical energy consumption and does not meet economic requirements. Therefore, in the absence of a major breakthrough in solving the battery technical problems, a more practical driving method is to use combined driving structure designs. Current combined driving structure designs include:

[0002] (A) Series Combined Power Design: This design is the most typical structure for an electrically driven vehicle. In this design a generator is driven by the engine to generate electricity and charge the...
