DETAILED DESCRIPTION

[0016] The utility model is further described below in combination with the drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the utility model are described by way of illustration. It is needless to say that those skilled in the art can realize that the described embodiments can be modified in various ways without departing from the spirit and scope of the utility model. Therefore, the drawings and description are illustrative in nature and are not used to limit the protection scope of the claims.

[0017] Embodiment one: as shown in Figure 1 And Figure 2 Dual-output hybrid power device, including engine 1, the engine 1 is installed on power output component 11, conventionally, the power output component 11 is flywheel, of course, can be output shaft structure, not limited here. The structure principle of the engine 1 is well-known technology, and here is not repeated.

[0018] The engine 1 is fixedly installed with generator shell 2 at power output component 11, the generator shell 2 is rotatably installed with power generation rotating shaft 21, and one end of the power generation rotating shaft 21 is fixedly connected with the power output component 11. The generator shell 2 is directly installed on the engine 1, and the power generation rotating shaft 21 is directly connected with the power output component 11, compact structure, and high power output efficiency. Among them, the connection of the power generation rotating shaft 21 and the power output component 11 can be realized by fixedly arranging disc structure connected with flywheel bolt on the power generation rotating shaft 21.

[0019] The generator shell 2 is provided with a plurality of stators 22 arranged in a circumferential direction, and the generator rotating shaft 21 is provided with a plurality of rotors 23. The generator generates electricity by means of magnetic field cutting between the rotors 23 and the stators 22 during rotation of the rotors 23, which is a known technology and will not be described herein. The stators 22 or the rotors 23 in the embodiment are excitation structures, which are structures in which excitation coils are wound on cores. After the excitation structures are energized, the corresponding stators 22 or rotors 23 generate magnetic fields, and the generator generates electricity when the generator rotating shaft 21 rotates. After the excitation structures are de-energized, no magnetic field cutting occurs during rotation of the generator rotating shaft 21, and the generator does not generate electricity.

[0020] The generator shell 2 is fixedly provided with a work output machine shell 3, and the work output machine shell 3 is rotatably provided with a work output shaft 31 connected with the generator rotating shaft 21. After the work output shaft 31 is connected with the generator rotating shaft 21, it is equivalent to being directly connected with the power output member 11, and the power of the engine 1 can be directly output to the working machine, and the work power transmission efficiency is high. Therefore, when the traction power is insufficient, the excitation structure in the embodiment is energized, the rotor 23 rotates, and the generator can generate electricity. At this time, the power of the engine 1 is kept for power output of the working machine, and the embodiment can simultaneously meet the traction and work requirements. When the power is sufficient or the work load is large, the excitation structure is de-energized, the generator does not generate electricity, the generator rotating shaft 21 rotates under no load, and the power of the engine 1 can be entirely output to the working machine, and the power conversion is convenient.

[0021] The connection between the work output shaft 31 and the generator rotating shaft 21 can be flange connection or spline connection, which is not limited herein. The work output machine shell 3 is first a machine shell for mounting the work output shaft 31, and then a machine shell for mounting other work output structures. Therefore, the work output machine shell 3 can not be a complete shell structure, but can be a whole of a plurality of shell bodies for mounting the work output shaft 31 and other work output structures.

[0022] The work output machine shell 3 is rotatably provided with a shift shaft 32, and a clutch 33 is arranged between the shift shaft 32 and the work output shaft 31. The power connection and disconnection between the working machine and the work output shaft 31 are controlled by combination or separation of the clutch 33, so as to better control whether the working machine works or not. The clutch 33 can be various forms such as a common hydraulic clutch 33 or an electromagnetic clutch 33, which is not limited herein.

[0023] Furthermore, a working connecting shaft 34 is rotatably mounted on the working output housing 3, and at least two sets of shift gears 35 are provided between the working connecting shaft 34 and the shift shaft 32. During operation, power transmission is achieved by selecting different shift gear sets 35, thus changing the final output speed of the working connecting shaft 34, to more conveniently coordinate with the power output control of the working machinery. The selection of the shift gear sets 35 is achieved by conventionally using a shift fork to engage a synchronizer 36, a well-known and commonly used method, which will not be elaborated upon here.

[0024] Preferably, a power transmission shaft 37 is rotatably mounted inside the work output housing 3, located between the work output shaft 31 and the shift shaft 32. A universal joint 38 is installed between the power transmission shaft 37 and the work output shaft 31, and a clutch 33 is provided between the power transmission shaft 37 and the shift shaft 32. Through the extension of the universal joint 38, the shift shaft 32 and the work connection shaft 34, etc., in this embodiment, can be conveniently arranged at the rear end of the traction chassis, facilitating the smooth connection between the power take-off structure of the work machinery and the work connection shaft 34, etc.

[0025] Example 2: Figure 3 As shown, the difference between this embodiment and Embodiment 1 lies in that the output of this embodiment differs from the mechanical structure of Embodiment 1; it is hydraulic. Specifically, a hydraulic pump 4 is fixedly mounted on the generator housing 2. The input shaft of the hydraulic pump 4 also serves as the output shaft 31, and the pump housing of the hydraulic pump 4 also serves as the output housing 3. High-pressure fluid is output via the hydraulic pump 4, and this high-pressure fluid serves as the power source to drive the relevant cylinders, pumps, or fan-like components in the working machinery. This achieves the same power output, and the connection between the hydraulic pump 4 and the working machinery only requires the arrangement of high-pressure pipelines, simplifying the power take-off connection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
