Description

Technical Field

[0001] The utility model belongs to the technical field of engine connection mechanisms, and particularly relates to an automatic transmission engine connection mechanism. Background Art

[0002] A diesel engine needs to be matched with a hydraulic automatic transmission. To achieve the power transmission between the engine and the transmission, a ring gear and a flexible disc are used to achieve the rigid connection between the two. The main problems in the current use of the ring gear and the flexible disc are as follows:

[0003] ① The center of the ring gear is basically coincident with that of the hydraulic torque converter. If the ring gear and the flexible disc are designed as a whole, the ring gear will block the assembly space of the bolts on the hydraulic torque converter and the flexible disc, and the final rigid connection between the engine and the transmission cannot be achieved;

[0004] ② The hydraulic torque converter assembled at the front end of the transmission needs to be positioned with the engine center to ensure concentricity during rotation. This requires the flexible disc and the ring gear to be coaxially arranged;

[0005] ③ The engine and the transmission are connected through a connection mechanism. In addition to the center positioning of the hydraulic torque converter, it is also necessary to consider overcoming the axial movement of the hydraulic torque converter. It is necessary to achieve rigid torque transmission and also take into account a certain amount of axial movement. Summary of the Utility Model

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present utility model. However, it will be apparent to those skilled in the art that the present utility model may be practiced without one or more of these details. In other instances, some well-known technical features are not described in order to avoid obscuring the present utility model.

[0025] It should be understood that the present utility model can be implemented in different forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present utility model to those skilled in the art. In the drawings, the same reference numerals throughout the drawings indicate the same components.

[0026] The specific structure of an automatic transmission engine connection mechanism in the present utility model is described in conjunction with Figures 1 to 3 , and this automatic transmission engine connection mechanism includes:

[0027] A flywheel 11, with a ring gear 10 fixed to one end of the flywheel 11, and a circular protrusion 12 at the other end of the flywheel 11;

[0028] A flexible disc 14, which is fixed to the protrusion 12, and there is an installation space 13 between the periphery of the flexible disc 14 and the flywheel 11.

[0029] Among them, the ring gear 10 is sleeved on the flywheel 11, and the installation space 13 isolates the flywheel 11 and the flexible disc 14 through the protrusion 12. The setting of the installation space 13 facilitates the fixing of the flexible disc 14 to the torque converter 17 by bolts 19. In this connection mechanism, the side of the flywheel 11 where the ring gear 10 is fixed is connected to the crankshaft 15 of the engine, and the side of the flexible disc 14 on the flywheel 11 is connected to the torque converter 17 of the transmission.

[0030] In the actual implementation process, an automatic transmission engine connection mechanism adds the flywheel 11 structure, fixes the ring gear 10 and the flexible disc 14 on both sides of the flywheel 11, and reserves an installation space 13 for the bolts 19 on one side of the flexible disc 14 to ensure that the engine and the transmission can be rigidly assembled; in addition, through the design of the flywheel 11, it can also take into account a certain amount of axial movement to ensure the smooth operation of the engine crankshaft 15.

[0031] In some embodiments, the flywheel 11, the ring gear 10, and the flexible disc 14 are all coaxially arranged. For example, Figure 3As shown, in this solution, since the installation space 13 for the flexible disk 14 is reserved by the flywheel 11, there is no need to adjust the size and axial position of the ring gear 10. The ring gear 10 and the flexible disk 14 are coaxially arranged under the action of the flywheel 11, so that the torque converter 17 on the transmission and the center of the engine can be coaxially connected, ensuring the concentricity during rotation.

[0032] In some embodiments, the ring gear 10 and the flywheel 11 are coaxially arranged, and the ring gear 10 and the flywheel 11 are fixedly connected by welding. For example, Figure 3 As shown, in order to firmly connect the ring gear 10 and the flywheel 11, after the ring gear 10 and the flywheel 11 are coaxially arranged, they are fixedly connected by welding to form an integral structure.

[0033] In some embodiments, the installation space 13 is the installation space 13 for the bolt 19, and the flexible disk 14 is fixedly connected to the torque converter 17 by the bolt 19. For example, Figure 3 As shown, the installation space 13 is mainly for the bolt 19 to extend into it to fixedly connect the flexible disk 14 and the torque converter 17.

[0034] In some embodiments, the protrusion 12 separates the flywheel 11 and the flexible disk 14, and the installation space 13 is located outside the protrusion 12 in the radial direction. For example, Figure 3 As shown, in the structure of the flywheel 11, the protrusion 12 is in a circular ring shape, which can separate the flywheel 11 and the flexible disk 14. There is a space outside the protrusion 12 in the radial direction, and this space is the installation space 13.

[0035] In some embodiments, the side of the flywheel 11 connected to the ring gear 10 is fixedly connected to the crankshaft 15 of the engine, the flexible disk 14 is connected to the torque converter 17, and the torque converter 17 is located inside the transmission housing 18. As Figure 3 shown, the left side of the flywheel 11 is fixedly connected to the crankshaft 15 of the engine by the bolt 19. After the right side of the flywheel 11 is connected to the flexible disk 14 by the bolt 19, the flexible disk 14 is fixedly connected to the torque converter 17 by the bolt 19, where the torque converter 17 is located inside the transmission housing 18.

[0036] In some embodiments, the transmission housing 18 wraps the outside of the flexible disk 14 and the flywheel 11. A back plate 16 is provided on the side of the flywheel 11 connected to the ring gear 10. The back plate 16 covers the flywheel 11 and the ring gear 10 and the back plate 16 is connected to the transmission housing 18. For example, Figures 1 to 3 As shown, the transmission housing 18 wraps this connection mechanism and covers it with the back plate 16, wrapping this connection mechanism inside to ensure the stability of the connection mechanism during use, and avoiding its radial displacement, and not restricting its axial movement.

[0037] In some embodiments, the back plate 16 is connected to the transmission housing 18 by bolts 19, the flexible disk 14 is connected to the torque converter 17 by bolts 19, and the flywheel is connected to the crankshaft 15 of the engine by bolts 19. For example, Figures 1 to 3 As shown, the back plate 16 and the transmission housing 18, the flexible disk 14 and the torque converter 17, and the flywheel and the crankshaft 15 of the engine are all connected by bolts 19. On the one hand, this can make the connection more firm, and on the other hand, it can facilitate the disassembly and assembly of this connection mechanism.

[0038] The above embodiments only illustrate the principles and effects of the present invention by way of example, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
