DETAILED DESCRIPTION

[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] Reference below Figures 1-4 A transmission device 10 for a vehicle and a vehicle having the same according to an embodiment of the present invention will be described.

[0021] like Figures 1-4 As shown, a vehicle transmission device 10 according to an embodiment of the present invention includes a torsional vibration damper 1 and a planetary gear train 2. The torsional vibration damper 1 includes a vibration damper hub 11, an elastic member 12, and a vibration damper plate 13. The vibration damper hub 11 and the vibration damper plate 13 are connected to each other through the elastic member 12. The planetary gear train 2 includes planetary gears 21, a sun gear, and a ring gear 22. The planetary gears 21 are connected to the vibration damper plate 13 and meshed between the sun gear and the ring gear 22. One of the vibration damper hub 11 and the sun gear serves as an input end, and the other of the vibration damper hub 11 and the sun gear of the planetary gear train 2 serves as an output end.

[0022] The vehicle's transmission 10 can be used to transmit torsional torque and reduce torsional vibration. One of the shock absorber hub 11 and the sun gear serves as the input end, while the other serves as the output end. That is, when the shock absorber hub 11 serves as the input end of the transmission 10, the sun gear serves as the output end. Alternatively, when the sun gear serves as the input end of the transmission 10, the shock absorber hub 11 serves as the output end of the transmission 10. The following example illustrates the transmission 10, using the shock absorber hub 11 as the input end and the sun gear as the output end. The transmission 10 can transmit power from the vehicle's engine to the vehicle's generator (e.g., a range extender motor) or hybrid transmission. It can also reduce noise, thereby improving the vehicle's NVH (noise, vibration, and harshness) performance.

[0023] like Figure 4 As shown, the crankshaft 20 of the engine can be connected to the shock absorber hub 11 in a transmission manner. As some embodiments of the present application, the crankshaft 20 of the engine can have an internal spline, and the shock absorber hub 11 can have an external spline. The internal spline of the crankshaft 20 can cooperate with the external spline of the shock absorber hub 11 to achieve the effect of transmitting the power of the engine to the shock absorber hub 11. The crankshaft 20 can drive the shock absorber hub 11 to rotate around the axis of the shock absorber hub 11.

[0024] In some embodiments of the present application, the elastic member 12 can be constructed as a coil spring, elastic rubber, or the like. The axis of the elastic member 12 can be perpendicular to the axis of the torsional vibration damper 1 , and the elastic member 12 has two opposing ends along its axis. In some embodiments of the present application, the damper hub 11 can abut one end of the elastic member 12 , the damper plate 13 can abut the other end of the elastic member 12 , and the planetary gear 21 can be connected to the damper plate 13 . In some embodiments of the present application, the planetary gear 21 can be rotatably connected to the damper plate 13 . For example, the planetary gear 21 can be rotatably disposed on a pivot shaft, which is fixedly connected to the damper plate 13 , and the planetary gear 21 is meshed between the sun gear and the ring gear 22 . The damper hub 11 can transmit power to the elastic member 12 , and the elastic member 12 can transmit power to the damper plate 13 . During this power transmission, the torsional vibration damper 1 can reduce the vibration amplitude caused by torsion and reduce the risk of resonance. The damper plate 13 then transmits the power to the planetary gear train 2 .

[0025] It can be understood that the sun gear can be connected to the input shaft 30 of the generator, and the power of the planetary gear 21 can be transmitted to the sun gear. After that, the sun gear transmits the power to the input shaft 30 of the generator, thereby achieving the effect of transmitting the power of the engine to the generator.

[0026] The transmission device 10 can be directly connected to the crankshaft 20 of the engine. The transmission device 10 can play the role of energy storage and release, power transmission and starting assistance. The present application connects the planetary gear 21 with the vibration damping plate 13, and the vibration damper hub 11 and the vibration damping plate 13 are connected through the elastic member 12. The flywheel, flywheel bolts, input shaft of the planetary mechanism and other components in the related art can be omitted to reduce the overall weight of the vehicle's engine and transmission device 10, reduce the space occupied by the power transmission system in the vehicle, and save manufacturing costs.

[0027] In the above embodiment, by connecting the planetary gear 21 to the vibration damping disk 13, and connecting the vibration damper hub 11 to the vibration damper disk 13 through the elastic member 12, power can be directly transmitted to the sun gear through the vibration damper hub 11, and components such as the flywheel, flywheel bolts, and input shaft of the planetary mechanism in the related art can be omitted. Moreover, by connecting the planetary gear 21 to the vibration damping disk 13, the planetary carrier of the traditional planetary gear can be omitted, thereby changing the traditional planetary gear mechanism. Moreover, the transmission device 10 of the present application is conducive to reducing the axial dimension and the number of components, thereby reducing the difficulty of layout, reducing costs, and improving maintenance convenience.

[0028] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the planetary gear system 2 also includes: a fixed frame 23, the fixed frame 23 includes: a frame body 231, a connecting portion 232, the planetary gear 21 is rotatably arranged on the frame body 231, the connecting portion 232 is fixedly connected to the frame body 231 and the vibration damping plate 13, the connecting portion 232, the frame body 231, and the vibration damping plate 13 together define an installation space 3, and part of the planetary gear 21 is accommodated in the installation space 3.

[0029] The frame body 231 and the vibration damping plate 13 can be arranged along the following lines: Figure 3 As shown, the planetary gears 21 are arranged at intervals in the first direction, which may be the same as the axial direction of the transmission device 10. The planetary gears 21 may be rotatably mounted on the frame body 231. The connecting portion 232 is fixedly connected to both the frame body 231 and the vibration damping plate 13. In other words, the connecting portion 232 may be connected between the frame body 231 and the vibration damping plate 13. The connecting portion 232, the frame body 231, and the vibration damping plate 13 may collectively define an installation space 3. Part of the planetary gears 21 may be located within the installation space 3 to protect the planetary gears 21, thereby facilitating stable operation of the planetary gears 21 and enabling a high degree of integration between the torsional vibration damper 1 and the planetary gear train 2, thereby improving the degree of integration of the transmission device 10. This arrangement can firmly install the fixing frame 23 and the vibration damping plate 13 together, so that the vibration damping plate 13 can reliably and smoothly transmit power to the frame body 231 through the connecting portion 232. The planetary gear 21 is rotatably arranged on the frame body 231. The frame body 231 can transmit power to the planetary gear 21, and then to the sun gear, and then to the input shaft 30 of the generator, so as to achieve the effect of driving the input shaft 30 of the generator to move, and the power transmission is stable and smooth. Moreover, by providing the fixing frame 23, and making the fixing frame 23 fixedly connected to the vibration damping plate 13, and the planetary gear 21 rotatably arranged on the frame body 231 of the fixing frame 23, it is beneficial to increase the torque transmission capacity of the transmission device 10, so that the transmission device 10 can reliably transmit large torque.

[0030] As some embodiments of the present application, the frame body 231 can be integrally formed with the connecting portion 232. This arrangement is easy to produce and easy to install. As some embodiments of the present application, the frame body 231 and the connecting portion 232 can be set as separate parts. The frame body 231 and the connecting portion 232 can be snap-connected, screwed, etc. This arrangement facilitates the separate manufacture of the frame body 231 and the connecting portion 232, and facilitates the replacement of failed parts.

[0031] In some embodiments of the present invention, Figure 1-Figure 3 As shown, there are multiple connecting parts 232 and elastic parts 12, multiple connecting parts 232 are arranged around, and multiple elastic parts 12 are arranged around. The elastic parts 12 correspond to the connecting parts 232 one by one, and along the radial direction of the transmission device 10, the connecting parts 232 are located on the outside of the corresponding elastic parts.

[0032] The number of connecting portions 232 can be two, three, or four, and multiple connecting portions 232 are arranged around the central axis of the vibration damping disc 13. The multiple connecting portions 232 can enhance the connection strength between the vibration damping disc 13 and the frame body 231. The number of elastic members 12 can be two, three, or four, and multiple elastic members 12 are arranged around the central axis of the vibration damping disc 13. The multiple elastic members 12 can enhance the stability of power transmission between the shock absorber hub 11 and the vibration damping disc 13. The number of elastic members 12 and the connecting portions 232 are the same and correspond one-to-one. In the radial direction of the transmission device 10, the connecting portions 232 can be located outside the corresponding elastic member 12. This arrangement improves force transmission, reduces the risk of stress concentration, and can transmit high torque.

[0033] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, there are multiple connecting parts 232 and multiple planetary gears 21, multiple connecting parts 232 are arranged around, and multiple planetary gears 21 are arranged around. Along the circumference of the transmission device 10, a planetary gear 21 is provided between any two adjacent connecting parts 232.

[0034] Among them, the number of connecting parts 232 can be two, three, four, etc., and multiple connecting parts 232 are arranged around the central axis of the vibration damping disk 13. Multiple connecting parts 232 can improve the connection strength between the vibration damping disk 13 and the frame body 231. The number of planetary gears 21 can be two, three, four, etc., and multiple planetary gears 21 can be arranged around the central axis of the vibration damping disk 13. Along the circumference of the transmission device 10, at least one planetary gear 21 can be provided between any two adjacent connecting parts 232. As some embodiments of the present application, one planetary gear 21 can be provided between any two adjacent connecting parts 232, that is, multiple connecting parts 232 and multiple planetary gears 21 are arranged alternately along the circumference of the transmission device 10. As some embodiments of the present application, two planetary gears 21 can be provided between any two adjacent connecting parts 232. This arrangement is reasonable and has a good force transmission effect, which can reduce the risk of stress concentration and reduce power transmission loss.

[0035] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the torsional vibration damper 1 further includes a corrugated plate 6 , which is constructed in a ring shape. The corrugated plate 6 is fixedly connected to the vibration damping plate 13 and the fixing bracket 23 , so that the fixing bracket 23 is fixedly connected to the vibration damping plate 13 .

[0036] Among them, the corrugated sheet 6 can be constructed in a ring shape, and the corrugated sheet 6 can be fixedly connected to both the vibration damping plate 13 and the fixing frame 23. In other words, the corrugated sheet 6 can be fixedly connected between the vibration damping plate 13 and the connecting portion 232. As some embodiments of the present application, the corrugated sheet 6 can be welded, screwed, etc. to the vibration damping plate 13. As some embodiments of the present application, the corrugated sheet 6 can be welded, screwed, etc. to the connecting portion 232.

[0037] As some embodiments of this application, Figure 3 As shown, along the first direction, at least a portion of the corrugated sheet 6 can be located on the side of the vibration damping disc 13 away from the frame body 231. When the vibration damping disc 13 and the connecting portion 232 are connected by the corrugated sheet 6, the distance between the vibration damping disc 13 and the frame body 231 can be reduced, thereby improving the torque transmission capability. In addition, by providing the corrugated sheet 6, certain manufacturing processes and molds of existing torsional vibration dampers can also be utilized to produce the transmission device 10 of the present application, thereby saving the R&D cycle and the cost of manufacturing molds.

[0038] As some embodiments of this application, Figure 1 As shown, the connecting portion 232 can be connected to the outer periphery of the frame body 231 to form a skeleton structure. This arrangement can improve the deformation resistance and load-bearing capacity of the fixing frame 23, and at the same time improve the force transmission effect, so that the fixing frame 23 can transmit large torque, and is conducive to reducing power transmission loss and improving the reliability of the transmission device 10.

The planetary gear 21 can rotate relative to the fixed frame 23 and the vibration damping plate 13 along the axial direction of the connecting shaft 4, and the planetary gear 21 is rotatable relative to the connecting shaft 4. This arrangement can improve the installation stability of the planetary gear 21 and reduce the risk of separation of the planetary gear 21 from the ring gear 22 and the sun gear. In addition, by passing the connecting shaft 4 through the fixed frame 23 and the vibration damping plate 13, the connection strength between the fixed frame 23 and the vibration damping plate 13 can be further improved, thereby improving the force transmission performance.

[0043] The gasket 5 can be sleeved on the connecting shaft 4 and positioned between the planetary gear 21 and the mounting bracket 23 to reduce the risk of failure of the planetary gear 21 or the mounting bracket 23 due to friction between the two. This also reduces abnormal noise, thereby improving the NVH (noise, vibration, and harshness) performance of the vehicle. The gasket 5 can be positioned between the planetary gear 21 and the damping plate 13 to reduce the risk of failure of the planetary gear 21 or the damping plate 13 due to friction between the two.

In some embodiments of the present application, the first body 111 can be configured as a cylindrical structure, and the second body 112 can be configured as a disc-like structure. This configuration is structurally sound and facilitates power transmission.

[0047] The first body 111 can be configured as one of the input end and the output end, that is, the first body 111 can be configured as the input end or the output end.

In the process of power transmission, the torsional vibration damper 1 may weaken the vibration amplitude caused by torsion and reduce the risk of resonance.

[0049] As some embodiments of the present application, the first body 111 can be integrally formed with the second body 112, which is easy to install. As some embodiments of the present invention, the first body 111 and the second body 112 can be set as separate parts, and the first body 111 and the second body 112 can be snap-connected, screwed, etc. This arrangement facilitates the separate manufacture of the first body 111 and the second body 112, and facilitates the replacement of failed parts.

By having the second body 112 between the two vibration damping discs 13, the length dimension of the transmission device 10 along the first direction can be further reduced to further reduce the space occupied by the vehicle.
