Description

Technical Field

[0001] This application belongs to the field of generator set technology, and in particular relates to a generator set and a vehicle. Background Technology

[0002] The vehicle's generator set is part of the vehicle's functional system, converting other forms of energy into electrical energy to power onboard equipment. However, because generator sets may have excessively long response times and insufficient power supply, vehicles are also equipped with additional energy storage devices to ensure overall power supply to the vehicle.

[0003] Currently, if high-power vehicles need to be powered, the energy storage device needs to be large. A large energy storage device will take up vehicle space and affect the vehicle's integration, making it difficult to ensure the vehicle's power supply effect while maintaining good integration. Summary of the Invention

[0004] This application aims to at least partially solve the technical problem of improving vehicle integration while ensuring adequate vehicle power supply. To this end, this application provides a generator set and a vehicle.

[0005] This application provides a generator set, including:

[0006] engine;

[0007] A generator, the generator input terminal of which is connected to the engine output terminal of the engine;

[0008] A gear speed increaser has an intervald speed increase input end and a speed increase output end. The speed increase input end is connected to the generator output end of the generator, and the operating speed of the speed increase output end is greater than the operating speed of the speed increase input end.

[0009] The flywheel mechanism is provided with a flywheel connected to the speed-increasing output end.

[0010] In some or more embodiments, the gear speed-increasing device includes:

[0011] The planetary gear carrier is configured as the speed-increasing input end;

[0012] A planetary gear mechanism, wherein the ring gear of the planetary gear mechanism is connected to the generator housing of the generator, the planetary gears of the planetary gear mechanism are rotatably connected to the planetary gear carrier, and the sun gear of the planetary gear mechanism is configured as the speed-increasing output end.

[0013] In some or more embodiments, the planetary gear carrier includes:

[0014] The frame is connected to the generator output terminal, surrounding it;

[0015] At least one connecting shaft is connected to the planetary gear support and passes through at least one of the planetary gears in a corresponding manner, with the connecting shaft and the corresponding planetary gear having a clearance fit.

[0016] In some or more embodiments, the gear speed-increasing device includes:

[0017] The speed-increasing housing is connected to the generator housing and has a speed-increasing cavity. The generator output end extends into the speed-increasing cavity and is connected to the speed-increasing input end located in the speed-increasing cavity.

[0018] In some or more embodiments, the generator output extends out of the rear end cover of the generator, and the speed-increasing housing is connected to the rear end cover of the generator.

[0019] In some or more embodiments, the flywheel mechanism includes:

[0020] A flywheel housing is connected to the gear speed-increasing device and has a flywheel cavity. The flywheel is rotatably disposed on the cavity wall of the flywheel cavity. The flywheel has a protrusion that is inserted into the gear speed-increasing device and is sealed with the gear speed-increasing device. The speed-increasing output end is inserted into the flywheel and fixed to the flywheel.

[0021] In some or more embodiments, the flywheel mechanism further includes:

[0022] The flywheel is rotatably mounted on the cavity wall of the flywheel cavity via a self-lubricating bearing.

[0023] In some or more embodiments, the speed-increasing output terminal is fixedly inserted into the flywheel and sealed with the flywheel.

[0024] In some or more embodiments, the generator set further includes:

[0025] At least four elastic support pads are respectively connected to both sides of the engine.

[0026] This application also provides a vehicle, including:

[0027] Movable chassis;

[0028] As described above, the generator set is mounted on the chassis and is used to drive the chassis to move.

[0029] The beneficial effects provided by one or more embodiments of this application are as follows:

[0030] The engine output is connected to the generator input, which in turn connects to the speed-input terminal of a gear speed-increasing device. The speed-output terminal of this device connects to the flywheel of the flywheel mechanism. This allows the engine to drive the generator, which in turn transmits power to the flywheel via the gear speed-increasing device. The generator's output energy is converted into the flywheel's rotational mechanical energy and stored. Since the speed-output terminal of the gear speed-increasing device operates at a higher speed than the input terminal, the flywheel's speed is also increased, thus enhancing its stored energy. When electrical compensation is needed, the inertially rotating flywheel drives the generator set to produce electricity. The gear speed-increasing device, in conjunction with the flywheel, significantly increases the flywheel's stored mechanical energy to meet the power demands of high-power vehicles. Furthermore, both the gear speed-increasing device and the flywheel require relatively little space, allowing for improved vehicle integration while simultaneously meeting the power needs of high-power vehicles. This addresses, to some extent, the technical challenge of simultaneously ensuring effective vehicle power supply and enhancing vehicle integration. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative end cap relationship and movement between the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0039] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0041] In related technologies, the energy supply capacity of energy storage devices in vehicles, such as batteries, is usually proportional to their volume. Therefore, to meet the energy supply needs of high-power vehicles, the energy storage device needs to be large. A large energy storage device will encroach on the space of other onboard equipment, and consequently, the vehicle itself may require a larger space, affecting its integration. This presents a technical problem of not being able to guarantee the energy supply effect while improving the vehicle's integration. This application provides a generator set and a vehicle, which can at least partially solve the above-mentioned technical problems.

[0042] The present application will now be described in conjunction with the accompanying drawings:

[0043] Figure 1 This application shows a schematic diagram of the structure of a generator set in some or certain embodiments. Figure 2 A partial cross-sectional view of a generator set in some or certain embodiments of this application is shown, with reference to... Figure 1 , 2 This application provides a generator set, including:

[0044] Engine 1.

[0045] Generator 2, with its input terminal 21 connected to the output terminal 11 of engine 1.

[0046] The gear speed increase device 3 has an interval speed increase input end 31 and speed increase output end 32. The speed increase input end 31 is connected to the generator output end 22 of the generator 2. The operating speed of the speed increase output end 32 is greater than the operating speed of the speed increase input end 31.

[0047] The flywheel mechanism 4 is equipped with a flywheel 41 connected to the speed-increasing output end 32.

[0048] The engine output terminal 11 is connected to the generator input terminal 21, the generator output terminal 22 is connected to the speed-increasing input terminal 31 of the gear speed-increasing device 3, and the speed-increasing output terminal 32 of the gear speed-increasing device 3 is connected to the flywheel 41 of the flywheel mechanism 4. Thus, the engine 1 can drive the generator 2 to rotate. When the generator 2 rotates, it transmits power to the flywheel 41 of the flywheel mechanism 4 through the gear speed-increasing device 3. The energy output by the generator 2 can be converted into the rotational mechanical energy of the flywheel 41 and stored through the gear speed-increasing device 3. Furthermore, the operating speed of the speed-increasing output terminal 32 of the gear speed-increasing device 3 is greater than the operating speed of the speed-increasing input terminal 31, so the speed of the flywheel 41 connected to the speed-increasing output terminal 32 can also be increased, and the energy stored in the flywheel 41 is increased. When electrical energy compensation is needed, the inertial rotating flywheel 41 can drive the generator set to generate electricity. The gear speed increaser 3, in conjunction with the flywheel 41, can significantly increase the mechanical energy that the flywheel 41 can store, in order to meet the energy supply needs of high-power vehicles. The gear speed increaser 3 and the flywheel 41 require relatively little space, which can improve the integration of the vehicle while meeting the energy supply needs of high-power vehicles. To a certain extent, this solves the technical problem of not being able to guarantee the energy supply effect of the vehicle while improving the integration of the vehicle.

[0049] Furthermore, while meeting the power supply requirements of vehicles with the same power output, the generator set in this application, compared to using some other energy storage devices, can save 20% of the vehicle's space, effectively improving the vehicle's integration. It is suitable for vehicles with high power requirements and limited interior space, such as off-road vehicles or power supply vehicles. The flywheel mechanism 4 is located at the end of the generator set's power transmission, facilitating its disassembly and assembly, and making maintenance of the flywheel mechanism 4 and gear speed-increasing device 3 easier. The low manufacturing, usage, and maintenance costs of the gear speed-increasing device 3 and flywheel mechanism 4 also contribute to reducing the manufacturing, usage, and maintenance costs of the generator set.

[0050] It should be noted that the operating speed of the speed increase input terminal 31 is the rotational speed of the speed increase input terminal 31 when the gear speed increase device 3 is in the working state. The operating speed of the speed increase output terminal 32 is the rotational speed of the speed increase output terminal 32 when the gear speed increase device 3 is in the working state.

[0051] In some or more embodiments, engine 1 may be a diesel engine. This is suitable for vehicles with high power demands. In some or more embodiments, the output end of the diesel engine may be a flexible coupling, the generator input end 21 may be the input shaft of generator 2, and the input shaft and the flexible coupling may be connected by a key. The generator output end 22 may be the output shaft of generator 2. This facilitates the connection between engine 1 and generator 2.

[0052] Figure 3 This application shows an assembly diagram of a gear speed increaser and a flywheel mechanism according to some or all embodiments of the present application. (Refer to...) Figure 3In some or more embodiments, the gear speed-increasing device 3 includes:

[0053] The planetary gear carrier 33 is configured as the speed-increasing input 31.

[0054] Planetary gear mechanism 34, the ring gear 341 of planetary gear mechanism 34 is connected to the generator housing 23 of generator 2, the planetary gear 342 of planetary gear mechanism 34 is rotatably connected to planetary gear support 33, and the sun gear 343 of planetary gear mechanism 34 is configured as speed-increasing output end 32.

[0055] The planetary gear carrier 33 serves as a transition structure, transmitting power from the generator output 22 to the planetary gear mechanism 34. The gear ring 341 of the planetary gear 342 structure is connected to the generator housing 23 of the generator 2, stabilizing the overall structure of the planetary gear 342. The planetary gear 342 of the planetary gear mechanism 34 is rotatably connected to the planetary gear carrier 33. When the planetary gear carrier 33 is driven to rotate by the generator output 22, the rotation of the planetary gear carrier 33 tends to push the planetary gear 342 to rotate relative to the sun gear 343. The planetary gear 342 can rotate relative to the planetary gear carrier 33 while simultaneously meshing with the sun gear 343, driving the sun gear 343 to rotate around its own axis. The power of the sun gear 343 can then be transmitted to the flywheel 41. The overall design requires little space, has high transmission density, and can significantly increase the energy that the flywheel 41 can store, effectively improving the vehicle's integration while meeting the power supply needs of high-power vehicles.

[0056] It should be noted that the planetary gear mechanism 34 includes a ring gear 341, a sun gear 343, and at least one planetary gear 342, wherein the sun gear 343 may be a gear shaft. The speed-increasing input terminal 31 and the speed-increasing output terminal 32 are indicated in parentheses in the accompanying drawings.

[0057] In some or more embodiments, the planetary gear carrier 33 includes:

[0058] The frame 331 is connected to the generator output terminal 22 around the generator output terminal 22.

[0059] At least one connecting shaft 332 is connected to the planetary gear support 33 and passes through at least one planetary gear 342 in a corresponding manner, with the connecting shaft 332 and the corresponding planetary gear 342 having clearance fit.

[0060] The planetary gear carrier 33 adopts the above structure. The structure of the planetary gear carrier 33 is relatively stable, and the connecting shaft 332 can drive the corresponding planetary gear 342 to rotate. The planetary gear 342 rotates around the connecting shaft 332 and simultaneously meshes with the sun gear 343 for transmission.

[0061] In some or more embodiments, the generator output end 22 can be the output shaft of the generator 2, and the frame 331 can be connected to the output shaft of the generator 2 around it. Multiple connecting shafts 332, spaced circumferentially along the output shaft, can be connected to the frame 331. The axial direction of the connecting shafts 332 can extend along the axial direction of the output shaft of the generator 2. The sun gear 343 of the planetary gear mechanism 34 can be coaxial with the output shaft of the generator 2, and multiple planetary gears 342 are correspondingly fitted onto multiple connecting shafts 332. This structure of the gear speed increaser 3 makes it very stable, provides a large transmission ratio, allows the flywheel 41 to store a large amount of energy, and minimizes the space occupied by the planetary gear mechanism 34. This effectively improves the energy supply efficiency and enhances the integration of the vehicle.

[0062] In some or more embodiments, the gear speed-increasing device 3 may also be a gearbox or similar structure with a large transmission ratio and simple structure. The input end and output end of the gearbox may be configured as a speed-increasing input end 31 and a speed-increasing output end 32, respectively. This can also achieve effective speed increase of the flywheel 41.

[0063] In some or more embodiments, the gear speed increaser 3 may include:

[0064] The speed-increasing housing 35 is connected to the generator housing 23 and has a speed-increasing cavity 351. The generator output end 22 extends into the speed-increasing cavity 351 and is connected to the speed-increasing input end 31 located in the speed-increasing cavity 351.

[0065] The speed-increasing housing 35 is connected to the generator housing 23, and the generator output end 22 extends into the speed-increasing cavity 351 of the speed-increasing housing 35. This can improve the integration between the gear speed-increasing device 3 and the generator 2, which is beneficial to reducing the overall volume required by the generator set and also to improving the integration of the vehicle.

[0066] It should be noted that when the gear speed-increasing device 3 includes a planetary gear mechanism 34, the gear ring 341 of the planetary gear mechanism 34 can be fixedly connected to the speed-increasing housing 35 to connect to the generator housing 23 of the generator 2. The overall strength is good.

[0067] In some or more embodiments, the generator output end 22 extends out of the rear end cover 24 of the generator 2, and the speed-increasing housing 35 can be connected to the rear end cover 24 of the generator 2. While ensuring overall strength, the speed-increasing housing 35 can also function as the original rear end cover on the generator 2, which can effectively reduce the axial length of the generator set and improve the overall integration of the vehicle.

[0068] In some or more embodiments, the generator housing 23 may also be connected to an opening on the housing of the engine 1, and the engine output end 11 or a flexible coupling may be located at the opening of the engine 1. This can improve the integration between the generator 2 and the engine 1, ensure the strength of the engine 1, and not increase the manufacturing cost of the engine 1.

[0069] In some or more embodiments, the flywheel mechanism 4 may include:

[0070] The flywheel housing 42 is connected to the gear speed-increasing device 3 and has a flywheel cavity 421. The flywheel 41 is rotatably disposed on the cavity wall of the flywheel cavity 421. The flywheel 41 has a protrusion 411 that is inserted into the gear speed-increasing device 3 and is sealed to the gear speed-increasing device 3. The speed-increasing output end 32 is inserted into the flywheel 41 and fixed to the flywheel 41.

[0071] The flywheel housing 42 is connected to the gear speed-increasing device 3 and has a flywheel cavity 421. The flywheel 41 is rotatably mounted on the cavity wall of the flywheel cavity 421. The flywheel 41 has a protrusion 411 that inserts into and seals with the gear speed-increasing device 3. The speed-increasing output end 32 is inserted into and fixed to the flywheel 41. The embedded connection structure improves the strength of the speed-increasing output end 32 and the flywheel 41 and enhances the overall integration. The sealing mechanism also improves the operational stability of the generator set.

[0072] In some or more embodiments, the flywheel housing 42 in the flywheel mechanism 4 can be connected and fixed to the speed-increasing housing 35 of the gear speed-increasing device 3. The speed-increasing housing 35 can be cylindrical and one end can be connected to the generator housing 23. The space corresponding to the inner peripheral wall of the speed-increasing housing 35 can form a speed-increasing cavity 351. The flywheel housing 42 can be a rotary structure and one end can be connected and fixed to the other end of the speed-increasing housing 35. The interior of the flywheel housing 42 can be hollowed out to form the flywheel cavity 421. This facilitates connection and has a high degree of overall integration.

[0073] In some or more embodiments, the flywheel mechanism 4 may further include:

[0074] The flywheel 41 is rotatably mounted on the wall of the flywheel cavity 421 via the self-lubricating bearing 43. This improves the safety of the flywheel mechanism 4 and extends its service life.

[0075] In some embodiments, the speed-increasing output terminal 32 is fixedly inserted into the flywheel 41 and sealed with it. This helps to improve the service life of the flywheel mechanism 4 and also facilitates the maintenance of the flywheel mechanism 4.

[0076] In some or more embodiments, the flywheel 41 may have an insertion hole 412 on the protrusion 411 that communicates with the flywheel cavity 421. The speed-increasing output end 32 can be fixedly inserted into the insertion hole 412, and a first seal 44 is provided between the speed-increasing end 32 and the hole wall of the insertion hole 412. The gear speed-increasing device 3 may include a second seal 36 disposed between the protrusion 411 and the speed-increasing housing 35, and a third seal 37 disposed between the speed-increasing housing 35 and the generator output end 22. The first seal 44, the second seal 36, and the third seal 37 may also be sealing rings or other structures. It has stable strength, high integration, and high sealing performance, and can play a certain role in heat insulation and may isolate lubricating grease, thereby improving the safety and stability of the generator set.

[0077] In some or more embodiments, the generator set further includes:

[0078] At least four elastic support pads 5 are connected to both sides of the engine 1. The elastic support pads 5 can play a certain role in vibration reduction and improve the operational stability of the generator set.

[0079] In some or more embodiments, the generator set includes multiple elastic support pads 5, and elastic support pads 5 can be provided on both sides of the engine 1 and the bottom of the generator 2. The overall stability of the generator set can be improved, with almost no vibration, and it provides good vibration reduction for larger or larger engines 1 and generator 2. The number of elastic support pads 5 in the generator set can be, for example, two or four, and two spaced elastic support pads 5 can be provided at the bottom of the generator housing 23. This provides good support and vibration reduction.

[0080] In some or more embodiments, the generator set may further include a cooling and heat dissipation assembly (not shown in the figure) for cooling the engine 1 and generator 2. The cooling and heat dissipation assembly may be a cooling water pipe or cooling water channel passing through the housing of the engine 1 or generator 2. This improves the operational stability of the generator set.

[0081] In some or more embodiments, at least two lubricating oil holes (not shown in the figure) communicating with the speed-increasing chamber 351 may be provided on the speed-increasing housing 35. The opening and closing of each lubricating oil hole can be controlled by blocking it. The generator set may also include air-cooling components such as fans installed on the vehicle body or flywheel housing 42. The air-cooling components such as fans can provide air cooling for the outer surface of the flywheel housing 42. The outer surface of the flywheel housing 42 may also be provided with multiple protrusions (not shown in the figure) or protruding heat dissipation fins (not shown in the figure). Lubricating oil can be injected into the speed-increasing chamber 351 through the lubricating oil holes to achieve cooling and lubrication of the planetary gear mechanism 34 in the speed-increasing chamber 351, thereby improving the operational stability of the gear speed-increasing device 3. At the same time, the air-cooling components such as fans can cool the flywheel mechanism 4, effectively improving the overall operational and usage stability of the generator set.

[0082] Based on the same inventive concept, this application also provides a vehicle. Figure 4 This application shows a simplified structural schematic diagram of a vehicle according to some or all embodiments thereof, with reference to... Figure 4 This application also provides a vehicle, which may include:

[0083] 20. Movable chassis.

[0084] As described above, the generator sets are respectively located at both ends of the chassis 20 and are used to drive the chassis 20 to move.

[0085] The structure of the generator set and its corresponding technical effects can be referred to above, and will not be repeated here. At least one generator set is set at each end of the chassis 20, which can effectively improve the vehicle's power supply effect. In addition, the generator set itself has a high degree of integration and requires little space, which can reduce the size of the vehicle itself to a certain extent. There is more space for installing other on-board equipment in the vehicle, which also helps to improve the vehicle's multi-functionality to a certain extent.

[0086] It should be noted that rotating wheels 20 can be installed on both sides of the vehicle chassis 20, and the chassis 20 moves through the wheels 20. The vehicle may also include a body structure (not shown in the figure) connected to the chassis 20, which can realize the basic driving function of the vehicle.

[0087] In some or more embodiments, the vehicle may also be an off-road vehicle, a multi-axle heavy-duty off-road vehicle, or an energy-assisted vehicle, and at least two generator sets may be spaced apart along the length of the chassis 20.

[0088] In some or more embodiments, when the generator set further includes elastic support pads 5 disposed on both sides of the bottom of the generator 2, the elastic support pads 5 can also be fixed to the vehicle body structure. This improves the installation stability of the generator set and provides a good vibration reduction effect.
