Description

A power-generating flywheel for retrofitting manual transmission cars Technical Field

[0001] This invention relates to the field of power-generating flywheel technology, and more particularly to a power-generating flywheel for installation on manual transmission vehicles. Background Technology

[0002] A manual transmission car is a car equipped with a manual gearbox. The driver needs to manually select different gear ratios by operating the clutch pedal and gear lever to meet different road conditions. The flywheel is an important component of the engine of a manual transmission car. It is connected to the gearbox through the clutch and transmits the power generated by the engine to the gearbox, and then to the drive wheels. At the same time, the rotational inertia of the flywheel can store energy during the power output stroke to maintain the smooth operation of the engine.

[0003] Since the flywheel is always rotating when a car brakes, some car manufacturers currently use the flywheel's rotational characteristics to generate electricity, partially recovering kinetic energy. However, when the vehicle or its onboard devices have a greater power demand, traditional generators are insufficient to meet the increased power requirements. In such cases, disc motors are used for power generation. Compared to traditional rotor motors, disc motors have advantages such as compact structure, small size, light weight, high torque density, and good heat dissipation, making them more suitable for automotive power generation.

[0004] However, since the flywheel of a manual transmission car needs to connect the engine and the transmission, it is necessary to ensure that the power transmission of the transmission is not affected when generating electricity through it. Since the engine crankshaft, flywheel and transmission input shaft are all coaxial, the installation of the power generation system on the flywheel is difficult. Furthermore, after the flywheel is connected to the engine crankshaft and transmission input shaft, it is difficult to maintain the relative speed between the stator core winding and the rotor disk with magnets in the power generation system, resulting in poor power generation effect. Therefore, it is necessary to design a power-generating flywheel for manual transmission cars. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a power-generating flywheel for installation on manual transmission vehicles, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A generator flywheel for retrofitting a manual transmission vehicle includes an engine and a gearbox. One end of the engine crankshaft is fixedly connected to a flywheel body. A gearbox input shaft is rotatably mounted on the gearbox and connected to the flywheel body via a clutch. A clutch cover is fixedly mounted on the side wall of the gearbox via multiple connecting pillars, and a connecting shaft is rotatably mounted on the clutch cover. The end of the clutch cover away from the gearbox is separated from the flywheel body. A clutch assembly is installed between the connecting shaft and the flywheel body, and a transmission assembly is installed between the connecting shaft and the gearbox input shaft.

[0008] An L-shaped rod is fixedly installed on the clutch cover, and a support ring is fixedly installed on the L-shaped rod. A generator shaft is rotatably installed on the support ring, and a generator assembly is installed between the generator shaft and the flywheel body. A through hole is provided on the connecting shaft to rotatably engage with the generator shaft.

[0009] Furthermore, the clutch cover has a rotating hole, and a bearing is installed between the rotating hole and the connecting shaft. A mating seat that is fixedly connected to the crankshaft is fixedly installed on the side wall of the flywheel body away from the clutch cover.

[0010] Furthermore, the clutch assembly consists of a friction plate, a friction disc, a pressure plate, and multiple springs. The friction plate is fixedly installed on the side wall of the flywheel body near the clutch cover. The friction disc is slidably installed on the connecting shaft, and a guide mechanism is installed between the friction disc and the connecting shaft. The pressure plate is slidably installed on the connecting shaft, and a circular hole that mates with the connecting shaft is opened on the pressure plate. Multiple springs are installed between the pressure plate and the clutch cover.

[0011] Furthermore, the guiding mechanism consists of two guide blocks and two guide grooves. The two guide blocks are fixedly installed on the side wall of the connecting shaft, and the two guide grooves are opened on the inner wall of the friction disc, and the two guide grooves cooperate with the two guide blocks respectively.

[0012] Furthermore, the transmission assembly consists of a rotating shaft, a connecting gear, and two fixed gear rings. The rotating shaft is rotatably mounted on the side wall of the clutch cover, the connecting gear is fixedly mounted on the rotating shaft, and the two fixed gear rings are respectively fixedly mounted on the gearbox input shaft and the connecting shaft, and both fixed gear rings mesh with the connecting gear.

[0013] Furthermore, the power generation assembly consists of a stator and a rotor. The rotor is fixedly installed on the side wall of the flywheel body near the clutch cover, and the stator is fixedly installed on the end of the power generation shaft located in the docking seat, and the stator and rotor cooperate with each other.

[0014] Furthermore, the thickness of the support ring is less than the minimum distance between the connecting shaft and the gearbox input shaft.

[0015] Compared with existing technologies, the advantages of this invention are:

[0016] This power-generating flywheel has the advantages of reasonable structure and stable power generation efficiency. Specifically, through the cooperation of the transmission component and the power generation component, the power generation effect is not affected by the clutch and gearbox. It can generate electricity continuously and stably when the flywheel body is rotating, without affecting the normal driving of the car. Attached Figure Description

[0027] Referring to Figures 1-9, a generator flywheel for adding to a manual transmission car includes an engine 1 and a gearbox 2. The engine 1 is an existing manual transmission car engine, which contains components such as a crankshaft, piston, intake manifold, and exhaust manifold. When working, the piston drives the crankshaft to rotate, providing a power source for the car's braking. The gearbox 2 is an existing manual transmission car manual gearbox, used to adjust the car's gears.

[0028] One end of the crankshaft of engine 1 is fixedly connected to a flywheel body 3. A mating seat 18, which is fixedly connected to the crankshaft, is fixedly installed on the side wall of the flywheel body 3 away from the clutch cover 4. A gearbox input shaft 6 is rotatably installed on the gearbox 2, and the gearbox input shaft 6 is connected to the flywheel body 3 through a clutch. A clutch cover 4 is fixedly installed on the side wall of the gearbox 2 through multiple connecting pillars 5. A rotating hole 7 is opened on the clutch cover 4, and a bearing is installed between the rotating hole 7 and the connecting shaft 9. The end of the clutch cover 4 away from the gearbox 2 is separated from the flywheel body 3, which can avoid the problem of the rotational resistance applied by the clutch cover 4 to the flywheel body 3 reducing the rotational speed and stability of the flywheel body 3.

[0029] A connecting shaft 9 is rotatably mounted on the clutch cover 4. A clutch assembly is installed between the connecting shaft 9 and the flywheel body 3. The clutch assembly consists of a friction plate 8, a friction disc 10, a pressure plate 14, and multiple springs 13. The friction plate 8 is fixedly mounted on the side wall of the flywheel body 3 near the clutch cover 4. The friction disc 10 is slidably mounted on the connecting shaft 9, and a guide mechanism is installed between the friction disc 10 and the connecting shaft 9. The pressure plate 14 is slidably mounted on the connecting shaft 9, and a circular hole 15 is opened on the pressure plate 14 to mate with the connecting shaft 9. The diameter of the circular hole 15 is larger than the diameter of the connecting shaft 9. Multiple springs 13 are installed between the pressure plate 14 and the clutch cover 4. The movement of the pressure plate 14 is the same as that of existing manual transmission cars. The driver can control the movement of the pressure plate 14 by pressing or releasing the clutch pedal. When the pressure plate 14 approaches the flywheel body 3, it can push the friction plate 10 to move towards the flywheel body 3 and eventually make it fit with the friction plate 8. At this time, the rotation of the flywheel body 3 can drive the connecting shaft 9 to rotate through the cooperation of the friction plate 8 and the friction plate 10, thereby providing driving force for the rotation of the gearbox input shaft 6. Conversely, when the pressure plate 14 moves away from the flywheel body 3, the friction plate 10 can separate from the friction plate 8 on the flywheel body 3, and the gear of the gearbox 2 can be controlled at this time.

[0030] To ensure that the friction disc 10 can separate from the flywheel body 3 when the pressure plate 14 is reset, a connecting ring can be rotatably set at one end of the pressure plate 14 near the friction disc 10, and an elastic component can be set between the connecting ring and the friction disc 10.

[0031] The guiding mechanism consists of two guide blocks 11 and two guide grooves 12. The two guide blocks 11 are fixedly installed on the side wall of the connecting shaft 9, and the two guide grooves 12 are opened on the inner wall of the friction disc 10. The two guide grooves 12 cooperate with the two guide blocks 11 respectively. With the cooperation of the guide blocks 11 and the guide grooves 12, the friction disc 10 can move back and forth on the connecting shaft 9, and ensure that the friction disc 10 can drive the connecting shaft 9 to rotate under the action of the flywheel body 3.

[0032] A transmission assembly is installed between the connecting shaft 9 and the gearbox input shaft 6. The transmission assembly consists of a rotating shaft, a connecting gear 16, and two fixed gear rings 17. The rotating shaft is rotatably mounted on the side wall of the clutch cover 4. The connecting gear 16 is fixedly mounted on the rotating shaft. The two fixed gear rings 17 are respectively fixedly mounted on the gearbox input shaft 6 and the connecting shaft 9, and both fixed gear rings 17 mesh with the connecting gear 16. When the connecting shaft 9 rotates, it can drive the connecting gear 16 to rotate through the fixed gear rings 17. In turn, under the action of the connecting gear 16 and the fixed gear rings 17 on the gearbox input shaft 6, the gearbox input shaft 6 is driven to rotate, thereby driving the gearbox 2.

[0033] An L-shaped rod 20 is fixedly installed on the clutch cover 4, and a support ring 21 is fixedly installed on the L-shaped rod 20. A generator shaft 22 is rotatably installed on the support ring 21. The thickness of the support ring 21 is less than the minimum distance between the connecting shaft 9 and the gearbox input shaft 6. The purpose of this dimension design is to avoid the presence of the support ring 21 affecting the transmission between the connecting shaft 9 and the gearbox input shaft 6, and to ensure that the transmission shaft 9 can effectively transmit power to the gearbox input shaft 6 under the action of the transmission components.

[0034] A power generation component is installed between the power generation shaft 22 and the flywheel body 3. A through hole 24 is provided on the connecting shaft 9 to rotate with the power generation shaft 22. The purpose of the through hole 24 is to prevent the rotation of the connecting shaft 9 from affecting the rotation of the power generation shaft 22, ensuring smooth power generation and ensuring power generation efficiency.

[0035] The power generation assembly consists of a stator 23 and a rotor 19. The rotor 19 is fixedly mounted on the side wall of the flywheel body 3 near the clutch cover 4. The stator 23 is fixedly mounted on the end of the power generation shaft 22 located in the docking seat 18, and the stator 23 and the rotor 19 cooperate with each other. Due to the design of the support ring 21 and the L-shaped rod 20, the power generation shaft 22 is mounted on the clutch cover 4. Due to the rotational arrangement between the clutch cover 4 and the flywheel body 3, the rotation of the flywheel body 3 will not affect the power generation shaft 22. Therefore, when the flywheel body 3 rotates, it can drive the rotor 19 to rotate relative to the stator 23. The rotor 19 is equivalent to the rotor disc with magnets in a disc motor, and the stator 23 is equivalent to the stator winding core in a disc motor. When the two rotate relative to each other, current can be generated by cutting magnetic lines of force, thus realizing power generation.

[0036] In this invention, the working principle of a power-generating flywheel for manual transmission vehicles includes the following steps:

[0037] Clutch control: The driver depresses or releases the clutch pedal to control the connection between the friction disc 10 and the friction plate 8, thereby connecting or separating the connecting shaft 9 and the flywheel body 3. When the friction disc 10 and the friction plate 8 are connected, the flywheel body 3 rotates, causing the connecting shaft 9 to rotate. At this time, under the operation of the transmission components, the gearbox input shaft 6 can be driven to rotate, providing drive for vehicle braking. When the friction disc 10 and the friction plate 8 are separated, the rotation of the flywheel body 3 will not drive the connecting shaft 9 to rotate. At this time, the driver can change gears.

[0038] Power generation process: When the flywheel body 3 rotates, since the generator shaft 22 is not in direct contact with the flywheel body 3, the flywheel body 3 rotates relative to the generator shaft 22. At this time, the inner rotor 19 and stator 23 can cut magnetic field lines to generate current. This power generation effect is not affected by the working state of the clutch, and the power generation is more stable.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
