Description

Technical Field

[0001] This utility model relates to the field of gear shifting equipment, specifically a gear shifting control component for automobiles. Background Technology

[0002] Previously, with the booming development of the automotive manufacturing industry, the application of automatic shifting components such as AT (automatic transmission), DCT (Dual Clutch Transmission), and CVT (Continuously Variable Transmission) has become more and more frequent, and their technology and functions have been developed to be more and more powerful. The newly derived electronic shifter module (GSM) has replaced the traditional mechanical shifter and is also widely used.

[0003] In related technologies, the most common types of electronic gear shifters are rotary electronic gear shifters and lever electronic gear shifters. Regardless of whether it is a rotary or lever electronic gear shifter, due to the limitation of its fixed mechanical structure, its shifting feel is fixed, that is, the force required to shift gears is fixed and cannot be adjusted.

[0004] Existing shifting components are prone to jerking during gear changes, have low transmission efficiency, large gearbox size, low torque, clutch wear, and short lifespan, among other issues. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a device that can conveniently use planetary gear trains and stator coils to perform stepless speed change.

[0006] To solve the above problems, the technical solution of this utility model is: an automotive gear shifting control component, including a gearbox body, a first planetary gear carrier, a first gear ring, a second gear ring, a generator stator, a second planetary carrier, a drive device stator, and a controller; The gearbox body is provided with a first gear ring and a second gear ring, which are connected to the stator of the generator and the stator of the drive unit through a controller. The power input shaft is connected to the first planetary gear carrier. The generator stator provides current and voltage to the drive unit stator through the controller. The power input shaft is connected to the first planetary gear carrier, which is provided with planetary gears. The planetary gears mesh with the first sun gear. The gearbox body is fixedly connected with a second planetary carrier, which is connected to the second planetary gears. The second planetary gears mesh with the second sun gear. The second sun gear is connected to the rotor of the drive unit. The second planetary gears are meshed with a second gear ring.

[0007] Furthermore, the generator stator coil includes a generator stator, which is located in the internal cavity of the gearbox body and has a generator rotor inside for cutting the generator stator.

[0008] Furthermore, the drive device stator coil includes a drive device stator, which is located in the internal cavity of the gearbox body and has a drive device rotor inside for cutting the drive device stator.

[0009] Furthermore, an output gear is fixedly connected to the outer sidewall of the gearbox body, and the output gear is sleeved with the power input shaft.

[0010] Furthermore, a controller is fixedly connected to one side wall of the gearbox body, and wires are connected to the controller to connect to the stator coil.

[0011] Furthermore, the gearbox body is a rigid structure, and its inner cavity is equipped with a rubber pad for sound insulation.

[0012] The advantages of this invention compared to existing technologies are as follows: This invention is applied to working scenarios such as automobile engines. The engine is equipped with a gear ring, which can output power from the gear ring or from planetary gears or sun gears. During the rotation of the differential, when power is input, the gearbox body generates electricity at low speed or when it does not rotate. This electricity is then transmitted to the drive unit via the controller. When there is no power, it is in neutral. The stator of the drive unit rotates clockwise, and the rotor of the drive unit rotates counterclockwise. Power is transmitted to the gearbox body through the gear ring. The gearbox body is equipped with output gears, thereby realizing speed change and achieving the effect of speed adjustment. During the adjustment process, the speed change of the power output wheel is linear, without obvious step differences. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0017] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figures 1 to 2 As shown, in a specific implementation, a car gear shifting control component includes a gearbox body 8, a first planetary gear carrier 2, a first ring gear 5, a second ring gear 12, a generator stator 7, a second planetary carrier 15, a drive unit stator 11, and a controller 9. The gearbox body 8 houses the first ring gear 5 and the second ring gear 12, which are connected to the generator stator 7 and the drive unit stator 11 via the controller 9. The power input shaft 1 is connected to the first planetary gear carrier 2. The generator stator 7 provides current and voltage to the drive unit stator 11 via the controller 9. The power input shaft 1 is connected to the first planetary gear carrier 2, which has planetary gears 3. The planetary gears 3 mesh with the first sun gear 4. The gearbox body is fixedly connected to the second planetary carrier 15, which is connected to the second planetary gear 14. The second planetary gear 14 meshes with the second sun gear 13. The second sun gear 13 is connected to the drive unit rotor 10. The second planetary gear 14 has the second ring gear 12 meshing with it.

[0020] In this embodiment, an output gear is fixedly connected to the outer side wall of the gearbox body 8, and the output gear is sleeved with the power input shaft 1. A controller 9 is fixedly connected to one side wall of the gearbox body 8, and wires are connected to the controller 9. The wires are connected to the stator coil. The gearbox body 8 is a rigid structure, and its inner cavity is provided with a rubber pad for sound insulation.

[0021] In practical use, the power input shaft 1 drives the first planetary gear carrier 2 to drive the planetary gears 3 to revolve. At low speed, the first sun gear 4 rotates fast and the first ring gear rotates slowly. The generator rotor 6 cuts the generator stator to generate electricity. The gearbox body 8 is fixed to the first ring gear 5 and the second ring gear 12 and fixed to the generator drive device. The controller 9 supplies power to the drive device stator 11, causing the drive device rotor 10 to reverse. The second sun gear 13 reverses, the second ring gear 12 rotates clockwise, the second planetary gear 14 rotates, and the second planetary carrier 15 is fixed and does not rotate.

[0022] First, this utility model can be used as a gear shifting component in automobiles and other applications. The automobile engine can be connected to the power input shaft. After the automobile engine is started, it can drive the power input shaft to rotate. The power input shaft can drive the first planetary gear carrier 2 to rotate. When the first planetary gear carrier 2 rotates, it can drive multiple planetary gears 3 to revolve synchronously.

[0023] When the first gear ring 5 rotates, it can drive the first power splitter to rotate, and drive the power input shafts 1 connected to the left and right sides of the first power splitter to rotate. When the controller 9 controls the power generation device to distribute voltage, at the same time, when the first gear ring 5 rotates, it can drive the second sun gear 13 to rotate through the transmission shaft. The second sun gear 13 can drive the second planet gear 14 to rotate, and the second planet gear 14 can drive the power output wheel to rotate. The power output wheel can be connected to the car wheel. Since the second gear ring 12 is not subjected to torsional force, it will not rotate, and the corresponding power output wheel rotates at a slower speed.

[0024] In this embodiment, the voltage and current of the drive device can be controlled by the controller 9. When the voltage and current of the drive device are large, the speed of the drive device is faster, the speed of the power input shaft 1 is also faster, the connecting shaft between the second power input shaft and the first power input shaft can drive the second gear ring 12 to rotate faster, and the corresponding power output wheel rotates faster.

[0025] In summary, the voltage and current of the drive device can be controlled by the controller 9, which in turn adjusts the speed of the power output wheel through the first gear set and the second gear set, thus achieving the function of speed change.

[0026] Furthermore, when braking is required, the car engine can still operate. The engine can drive the first ring gear 5 to rotate via the power input shaft. When the first ring gear 5 rotates, it can drive the second sun gear 13 to rotate via the hollow drive shaft. Because the car is in braking condition, the second planetary carrier 15 will not be driven, and similarly, the power output wheel will not be driven. As the second planetary gear 14 rotates in place, it drives the second ring gear 12 to rotate in the opposite direction. This also drives the first sun gear to rotate in the opposite direction, and the power will flow back to the first planetary gear set. However, this rotation does not affect the first planetary gear set or the engine.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
