Meanwhile, the generator is driven to work through a belt wheel system at the front end of the engine, and the whole storage battery is charged.
The silicone oil clutch has a large energy loss because of the inevitable slip between the fan and the drive shaft due to its operating principle. Meanwhile, the silicone oil clutch fan cannot meet the cooling requirements of the engine under the working conditions of high speed and large load and low speed and large load at the same time, namely the silicone oil clutch fan has the problems of insufficient cooling capacity at low speed or over-strong cooling capacity at high speed. In addition, the silicone oil clutch fan has the problem of slow speed regulation response.
The electromagnetic clutch fan usually only has one-gear or two-gear speed regulation, the gear shifting impact is large, the stepless speed regulation cannot be realized, and the problem of insufficient low-speed capacity or over-strong cooling capacity at high speed exists in the same way as a silicone oil clutch fan.
The mechanical fan is directly connected with the engine through a belt wheel system at the front end of the engine, so that the mechanical fan always rotates along with the engine in the working process of the engine, and the mechanical fan has the main defects that: the rotating speed of the fan cannot be adjusted, and energy is wasted when the engine has no cooling requirement, so that the conventional mechanical fan is rarely applied to a commercial vehicle.

When the heat dissipation requirement of the engine is increased, namely the rotating speed of the fan needs to be increased, the negative torque of the motor 2 is increased, the rotating speed of a planet carrier in the planetary gear train 7 is reduced, the forward rotating speed of the outer gear ring is increased at the moment, and the rotating speed of the fan 6 is further increased; when the heat dissipation requirement of the engine is reduced, namely the rotating speed of the fan is reduced, the negative torque of the motor 2 is reduced, the rotating speed of a planet carrier in the planetary gear train 7 is increased, the forward rotating speed of the outer gear ring is reduced at the moment, and further the rotating speed of the fan 6 is reduced. The motor can realize stepless speed change within the external characteristic torque range, thereby achieving the purpose of stepless speed regulation of the fan 6.
Meanwhile, as shown in fig. 6 to 8, in the working state of the fan, most working conditions of the motor are in a power generation state, the power generation power is equivalent to the power of the motor matched with a conventional engine, and only a few working conditions of the motor are in a driving state, so that the electric quantity of the battery is not excessively consumed; when the fan does not need to work and the electric quantity of the storage battery of the whole vehicle is insufficient, the motor is used as a generator.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. It is obvious that the invention is not limited to the above-described embodiments, but that many variations are possible. Any simple modification, equivalent change and modification made to the above embodiments in accordance with the technical spirit of the present invention should be considered to be within the scope of the present invention.
Here, it should be noted that the description of the above technical solutions is exemplary, the present specification may be embodied in different forms, and should not be construed as being limited to the technical solutions set forth herein. Rather, these descriptions are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Furthermore, the technical solution of the present invention is limited only by the scope of the claims.
The shapes, sizes, ratios, angles, and numbers disclosed to describe aspects of the specification and claims are examples only, and thus, the specification and claims are not limited to the details shown. In the following description, when a detailed description of related known functions or configurations is determined to unnecessarily obscure the focus of the present specification and claims, the detailed description will be omitted.
Where the terms "comprising", "having" and "including" are used in this specification, there may be another part or parts unless otherwise stated, and the terms used may generally be in the singular but may also be in the plural.
It should be noted that although the terms "first," "second," "top," "bottom," "side," "other," "end," "other end," and the like may be used and used in this specification to describe various components, these components and parts should not be limited by these terms. These terms are only used to distinguish one element or section from another element or section. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, with the top and bottom elements being interchangeable or switchable with one another, where appropriate, without departing from the scope of the present description; the components at one end and the other end may be of the same or different properties to each other.
Further, in constituting the component, although it is not explicitly described, it is understood that a certain error region is necessarily included.
In describing positional relationships, for example, when positional sequences are described as being "on.. above", "over.. below", "below", and "next", unless such words or terms are used as "exactly" or "directly", they may include cases where there is no contact or contact therebetween. If a first element is referred to as being "on" a second element, that does not mean that the first element must be above the second element in the figures. The upper and lower portions of the member will change depending on the angle of view and the change in orientation. Thus, in the drawings or in actual construction, if a first element is referred to as being "on" a second element, it can be said that the first element is "under" the second element and the first element is "over" the second element.
