217b425 MULTIPLE FUNCTIONED COMBINED POWER SYSTEM
BACKGROUND OF THE INVENTION
In recent years, energy and noise pollution problems have become more and more serious. A good solution to these problems would be to use the electrical power driven vehicles, but development of the electrical power driven vehicles has up to now been limited by the capacity of the batteries to achieve a larger moving range. Simply increasing the battery volume or quantity so as to increase the range will correspondingly increase the self-weight of the carrier, resulting in higher electrical 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:
(A) Series Combined Power Design: This design is the most typical structure for an electrically driven vehicle. In this design, the generator is driven by the engine to generate electricity and charge the battery, after which the 5 battery provides electricity to the driven motor to drive the vehicle. As the energy is converted several times, the overall efficiency of this design is low.
An example of this design is the GM HX3 vehicle of General Motors.
(B) Synchronized Power on Common Shaft Design: This design involves directly series combining the engine power output shaft and the rotating shaft of the driven motor, to thereby generate driving and speed controlling functions.
An example of this design is West Germany's Volkswagen CHICO Sedan.
For the case of the conventional engine and motor described in (8), only one of the engine and motor can be selected for output transmission and the combination of their power output is not available.
SUMMARY OF THE INVENTION
This invention relates to a multiple function combined power system which is used in driving machinery such as vehicles, ships, flying machines or other mechanical structures, or other industrial or processing equipment, in rotational driving applications, and in which the rotational output shaft of an internal combustion engine is coupled with an electrical machine through transmission gears, belts, or chains which constitute a particular transmission device installed between the electrical machine, engine and the output shaft:
The electrical machine is a series exerted or auxiliary compound excited electrical machine with the electrical characteristic that its rotational speed increases with a decreasing load, or an AC or DC brush or brushless machine able to perform current control, including constant current control to provide a load-following value-added torque function, and is coupled with the engine output shaft through a particular transmission device operated in two system modes following the driving direction of the electrical machine, by means of a one-way clutch and an eccentric clutch in cooperation with control of the rotation directions of the electrical machine to cause t'1 ) the electrical machine to start the engine, (2) the electrical machine to be used as a generator during engine operation, (3) the electrical machine and the engine to drive the load at the same time during the engine operation, t4) the electrical machine to drive the load, and (5) when the load is standing still, the engine to drive the electrical machine in a generator mode to charge the battery or other electrical loads.

Figure 7 shows the seventh preferred embodiment of the multiple function combined power system of the invention, including the following elements:
~ An internal combustion engine IC101 as described above;
~ An electrical machine E101 as described above, wherein the rotation shaft S401 has a double ended structure, one end of the output clutch CL401 being combined with the output gear box GB401, while the other end is combined with one end of the electrical machine output shaft S401, and the loads are driven by the output shaft S403 of a gear box GB401. The other end of the electrical machine output shaft S401 is combined with the rotating shaft S400 of the engine IC 101 through the one way transmission device SWC401, while the eccentric clutch FC401 is installed between the engine rotating shaft S400 and the electrical machine rotating shaft S401 and is responsive to the rotational speed to control the friction disk to have its drive side combined with engine rotating shaft S401.

Figure 8 shows the eighth preferred embodiment of the multiple function ~S combined power system of the invention, including the following elements:
~ An internal combustion engine IC101 as described above;
~ An electrical machine E101 as described above, wherein the rotation shaft S401 has a double-ended structure, one end of vvhich is combined with output gear box 68401, and the loads are driven by the output shaft S403 of 30 the said gear box GB401. The other end of the electrical machine output shaft S401 is combined with the rotating shaft S400 of the engine IC 101 through the
-10-.~ ~ ~ 217~4~5 one way transmission device SWC401 while the eccentric clutch FC401 is installed between the engine rotating shaft S400 and the electrical machine rotating shaft S401 and is arranged to be responsive to the rotational speed to cause a friction disk to have its drive side combined with engine rotating shaft S400 and its driven side combined with electrical machine rotating shaft S401.
The gear box GB401 is designed to maintain a same rotation direction output whether or not the driving input shaft is in positive or reverse rotations;
~ A manual control interface M 101 as described above;
~ A central controller CCU101 as described above;
~ A drive controller D101 as described above;
Functions of this embodiment are shown in Table 8.
The transmission methods of same rotation direction at different shafts and the matched positions of the engine, the electrical machine or the one-way transmission components adopted in the above examples can be flexibly applied as follows without departing from the principles of the invention.
( 1 ) Besides the cases mentioned in the above examples, the one-way transmission structure of the invention can be located at any shaft to provide fixed relative motions according to their transmission direction relationships;
(2) The engine driving interface can be located on shafts having fixed relative motion relationships in the transmission structure coupled With the engine rotating shaft;
(3) The electrical machine driving interface can be located on shafts having fixed relative motion relationships in the transmission structure coupled with the electrical machine rotating shaft, while the external output/input can be provided at one end or at two respective ends;
- 11 -.' 2176425 (4) The output eccentric clutch FC 102 can be incorporated in different rotational speed relationships, for example by selecting it to have a higher closing and releasing rotation speed than the eccentric clutch FC101 installed between the electrical machine and the engine, so that the engine can be operated at low speed and the clutch maintained released while the battery is charged at standstill;
(5) The eccentric clutch for starting the engine can be selected to close at a rotation speed which is higher than the rotation speed of the motor during a no load condition when the motor is in the independent load driving function, to thereby prevent the motor 15 from driving the engine during its load driving.
As summarized from the above descriptions, this design adopts a particular transmission structure coupled with the engine and the electrical machine, and thereby enables selection between having the motor start the engine or produce an independent driving output through the positive and 20 reverse rotations of the electrical machine. For loads requiring only one-way driving, such as the motorcycles, the claimed structure is easy to operate is most practically effective for vehicles in the heavy stop and go traffic of cities.
