Description

Technical Field

[0001] This application relates to the field of automotive driveshaft technology, and in particular to a transmission device for automotive driveshafts. Background Technology

[0002] The torque generated by the engine is transmitted to the drive shaft after being changed in speed and torque by the transmission. During vehicle operation, the angle and length of the drive shaft will change continuously due to the movement of the suspension and the vibration of the vehicle body. The universal joint and intermediate support can effectively adapt to these changes, ensuring stable torque transmission, while reducing wear and noise in the transmission system.

[0003] However, existing technologies still have the following problems:

[0004] Most existing automotive driveshaft transmission devices are integral structures, requiring specific tools and professional personnel for assembly, which is difficult, inefficient, and prone to installation errors. During later maintenance, damage to components often requires complete disassembly, which is cumbersome and time-consuming.

[0005] In response to the aforementioned technologies, the inventors propose a transmission device for an automotive driveshaft to solve the above problems. Utility Model Content

[0006] The purpose of this application is to provide a transmission device for an automotive driveshaft, so as to improve the problem of inconvenient assembly and maintenance of driveshaft transmission devices.

[0007] The transmission device for an automotive driveshaft provided in this application adopts the following technical solution:

[0008] A transmission device for an automotive drive shaft includes a sleeve, one side of which is provided with a post, and both the post and the outer end of the sleeve are fixedly provided with an inner U-shaped plate. The outer side of the inner U-shaped plate is provided with a mounting plate, and the outer side of the mounting plate is fixedly provided with a spline shaft. The outer end of the spline shaft is fitted with a spline sleeve, and the inner side of the spline sleeve is provided with a spline groove for use with the spline shaft. The outer surface of the spline sleeve is fixedly provided with a fixing plate.

[0009] By adopting the above technical solution, the spline groove of the spline shaft and spline sleeve can be used to achieve efficient and precise torque transmission and reduce slippage during power transmission. At the same time, the connection between the fixed plate and the spline sleeve can stably output power, while the connection between the insert, sleeve and inner U-shaped plate and mounting plate establishes a stable path for power transmission, ensuring that power can be smoothly transmitted from one place to another.

[0010] Optionally, a cross post is rotatably provided inside the inner U-shaped plate, and an outer U-shaped plate is rotatably connected to the cross post, wherein the outer U-shaped plate is fixedly connected to the corresponding mounting plate.

[0011] By adopting the above technical solution, the rotating connection structure between the cross column and the inner U-shaped plate and the outer U-shaped plate enables the drive shaft to flexibly adapt to angle changes caused by suspension movement, road bumps, etc. during vehicle operation, ensuring that power transmission is not affected by the angle deviation of the drive shaft, and enhancing the adaptability and stability of the transmission device under complex working conditions.

[0012] Optionally, the inner side of the fixing plate is symmetrically fixed with threaded tubes, and the threaded tubes are threaded with fixing bolts. The mounting plate is symmetrically provided with bolt grooves for use with the fixing bolts.

[0013] By adopting the above technical solution, the threaded pipe, fixing bolt and bolt groove are connected to firmly combine the fixing plate and the mounting plate. During power transmission, the two can be guaranteed to rotate synchronously and avoid relative displacement, thereby effectively improving the reliability and stability of power transmission.

[0014] Optionally, a reinforcing ring is movably fitted on the outer surface of the spline shaft, and the reinforcing ring is connected to the corresponding mounting plate by bolts.

[0015] By adopting the above technical solution, the reinforcing ring is fitted onto the outer surface of the spline shaft by bolts and mounting plate. When the spline shaft transmits high torque, it can effectively share the stress of the connection part, reduce the deformation and vibration of the connection area between the spline shaft and the mounting plate, significantly enhance the structural strength of the connection part, and extend the service life of the component.

[0016] Optionally, a chuck is fixedly provided on the inner side of the spline shaft, and the chuck is fixedly engaged on the outer side of the corresponding mounting plate.

[0017] By adopting the above technical solution, the chuck is fixedly mounted on the outside of the mounting plate, realizing a tight and stable connection between the spline shaft and the mounting plate. During power transmission, the torque on the spline shaft can be stably transmitted to the mounting plate, ensuring the stability of the power transmission path and preventing power transmission interruption or instability.

[0018] Optionally, the insert damper is inserted into one end of the sleeve.

[0019] By adopting the above technical solution, the insert damper is inserted into the sleeve, which enables the drive shaft to adaptively change its length according to the suspension movement, road surface undulations, and other conditions when the vehicle is in motion. The damping characteristics can also buffer the vibration and impact generated during the extension and contraction process, ensuring the continuity of power transmission and improving the reliability of the vehicle's transmission system.

[0020] Optionally, four threaded tubes and fixing bolts are provided on one side, and the four threaded tubes and fixing bolts are respectively distributed in a rectangular shape.

[0021] By adopting the above technical solution, the four rectangularly distributed threaded pipes and fixing bolts can evenly distribute the force between the fixing plate and the mounting plate. Compared with connection methods with fewer or unreasonable distribution, this layout greatly improves the stability of the connection structure and ensures that the fixing plate and the mounting plate always maintain synchronous and stable rotation during power transmission.

[0022] Optionally, the inner U-shaped plate has symmetrical through-hole inner connecting grooves on both sides, and the outer U-shaped plate has symmetrical through-hole outer connecting grooves on both sides. The two ends of the cross post are engaged in the corresponding inner connecting grooves, and the other two ends of the cross post are engaged in the corresponding outer connecting grooves.

[0023] By adopting the above technical solution, the two ends of the cross post are locked in the inner and outer connecting grooves. This structural design further restricts the movement trajectory of the cross post, while ensuring that it can rotate flexibly within a certain angle range. During vehicle operation, when the angle of the drive shaft changes, it can more accurately adapt to the angle change, making the power transmission from the mounting plate to the inner U-shaped plate more stable and efficient.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] The components of this application, such as sleeves, inserts, mounting plates, spline shafts, and spline sleeves, constitute a modular structure. Each component can be manufactured, installed, and disassembled independently. This design greatly facilitates the production and assembly process and reduces assembly difficulty. In later maintenance, if a component is damaged, the damaged component can be directly replaced without disassembling the entire drive shaft transmission device, which shortens maintenance time, reduces maintenance costs, and improves the ease of maintenance of the automotive transmission system.

[0030] The following is in conjunction with the appendix Figure 1- Appendix Figure 3 This application will be described in further detail below.

[0031] Example

[0032] A transmission device for an automotive driveshaft, with reference to Figure 1-3 The system includes a sleeve 1, with a insertion post 11 on one side. The insertion post 11 is damped and inserted into one end of the sleeve 1. Both the insertion post 11 and the outer ends of the sleeve 1 are fixed with inner U-shaped plates 2. A mounting plate 3 is provided on the outer side of the inner U-shaped plates 2, and a spline shaft 32 is fixed on the outer side of the mounting plate 3. A spline sleeve 33 is fitted on the outer end of the spline shaft 32. A spline groove 38 is opened on the inner side of the spline sleeve 33 to cooperate with the spline shaft 32. A fixing plate 34 is fixed on the outer surface of the spline sleeve 33. During vehicle operation, when power is transmitted to the spline shaft 32, the spline shaft 32 and the spline sleeve 33 pass through the spline groove. The interlocking of 38 and spline shaft 32, with the multi-tooth structure of the spline, allows for stable meshing, thereby transmitting torque precisely and efficiently to spline sleeve 33, which in turn drives fixed plate 34 to rotate. The insert 11 is damped and inserted into sleeve 1. When the vehicle is in motion, the suspension movement or road bumps will cause the length of the drive shaft to change. At this time, insert 11 can extend and retract within sleeve 1. The damping characteristics can buffer the vibration and impact during the extension and retraction process, ensuring the continuity of power transmission. At the same time, the inner U-shaped plate 2 at the outer end of insert 11 and sleeve 1 is connected to mounting plate 3, further transmitting power from insert 11 and sleeve 1 to subsequent structures.

[0033] A chuck 310 is fixedly mounted on the inner side of the spline shaft 32, and the chuck 310 is fixedly mounted on the outer side of the corresponding mounting plate 3. A reinforcing ring 39 is movably sleeved on the outer surface of the spline shaft 32, and the reinforcing ring 39 is connected to the corresponding mounting plate 3 by bolts. The chuck 310 is fixedly mounted on the outer side of the mounting plate 3, which realizes a firm connection between the spline shaft 32 and the mounting plate 3. During power transmission, the torque on the spline shaft 32 can be stably transmitted to the mounting plate 3, ensuring the stability of the power transmission path. The reinforcing ring 39 is connected to the mounting plate 3 by bolts and sleeved on the outer surface of the spline shaft 32. When the spline shaft 32 transmits high torque, the reinforcing ring 39 can share the force of the connection part, reduce the deformation and vibration of the connection part between the spline shaft 32 and the mounting plate 3, enhance the structural strength and stability of the part, and ensure that the components will not be damaged due to excessive force during power transmission.

[0034] Threaded tubes 35 are symmetrically fixed on the inner side of the fixed plate 34, and fixing bolts 36 are threaded inside the threaded tubes 35. Bolt slots 37 for use with fixing bolts 36 are symmetrically opened on the mounting plate 3. There are four threaded tubes 35 and fixing bolts 36 on one side, and the four threaded tubes 35 and fixing bolts 36 are respectively rectangularly distributed. When the spline sleeve 33 drives the fixed plate 34 to rotate, the threaded tubes 35 on the inner side of the fixed plate 34 and the bolt slots 37 on the mounting plate 3 are connected by the fixing bolts 36 to form a stable connection structure. The four rectangularly distributed threaded tubes 35 and fixing bolts 36 can evenly distribute the force between the fixed plate 34 and the mounting plate 3, ensuring that the two rotate synchronously, so that the power can be stably transmitted from the fixed plate 34 to the mounting plate 3, ensuring the reliability and stability of power transmission.

[0035] The spline connection between the spline shaft 32 and the spline sleeve 33, as well as the installation structure of the threaded tube 35 and the fixing bolt 36, make it convenient to install and disassemble the components. When repairing or replacing components, it can be quickly disassembled and assembled, reducing the difficulty and cost of maintenance and improving maintenance efficiency.

[0036] A cross post 21 is rotatably mounted inside the inner U-shaped plate 2, and an outer U-shaped plate 22 is rotatably connected to the cross post 21. The outer U-shaped plate 22 is fixedly connected to the corresponding mounting plate 3. Symmetrical through-hole inner connecting grooves 23 are provided on both sides of the inner U-shaped plate 2, and symmetrical through-hole outer connecting grooves 24 are provided on both sides of the outer U-shaped plate 22. Both ends of the cross post 21 are engaged in the corresponding inner connecting grooves 23, and the other two ends are engaged in the corresponding outer connecting grooves 24. When the mounting plate 3 rotates, it drives the outer U-shaped plate 22, which is fixedly connected to it, to rotate. The outer U-shaped plate 22 is connected to the cross post 21 by rotation. Then, the power is transmitted to the cross post 21. During the rotation, the two ends of the cross post 21 are locked in the inner connecting groove 23 of the inner U-shaped plate 2, and the other two ends are locked in the outer connecting groove 24 of the outer U-shaped plate 22. This structure allows the cross post 21 to rotate flexibly within a certain angle range. When the angle of the drive shaft changes during vehicle operation, the rotational connection between the cross post 21 and the inner U-shaped plate 2 and the outer U-shaped plate 22 can adapt to this angle change, ensuring that the power can be smoothly transmitted from the mounting plate 3 to the inner U-shaped plate 2, and then to the insert post 11 and the sleeve 1, so as to achieve stable power transmission.

[0037] The damped insertion design of the insert 11 and the sleeve 1, as well as the rotating connection structure of the cross 21 and the inner and outer U-shaped plates 22, enable the transmission device to effectively adapt to changes in the length and angle of the drive shaft during vehicle operation. Whether the vehicle is driving on a bumpy road or the suspension is compressing or extending, it can ensure the stability of power transmission, reduce power loss and component damage caused by drive shaft deformation and angle deviation, and improve the reliability and durability of the automotive transmission system.

[0038] The implementation principle of this application embodiment is as follows: During the driving process of the car, after the power is output by the engine, it is transmitted to the transmission device through components such as the transmission. When the power is transmitted to the spline shaft 32, the spline shaft 32 and the spline sleeve 33 can stably transmit the torque to the spline sleeve 33 through the mutual cooperation of the spline groove 38 and the spline shaft 32, thereby driving the fixed plate 34 to rotate. The fixed plate 34 is connected to the mounting plate 3 through the threaded tube 35 and the fixing bolt 36, so that the mounting plate 3 rotates together with the fixed plate 34.

[0039] When the mounting plate 3 rotates, the power is transmitted to the cross post 21 through the rotational connection between the outer U-shaped plate 22 and the cross post 21. The cross post 21 then transmits the power to the inner U-shaped plate 2 through the rotational connection with the inner U-shaped plate 2, which ultimately drives the insert post 11 and the sleeve 1. The insert post 11 is damped and inserted into the sleeve 1. This structural design allows the insert post 11 to have a certain amount of extension and retraction within the sleeve 1, which can adapt to the changes in the length of the drive shaft caused by suspension movement, road bumps, etc. during vehicle operation, and ensure the continuous transmission of power.

[0040] Meanwhile, the rotatable connection between the cross column 21 and the inner U-shaped plate 2 and the outer U-shaped plate 22 allows the device to rotate flexibly within a certain angle range to adapt to changes in the angle of the drive shaft, ensuring that power can be efficiently and stably transmitted to subsequent components under different working conditions, ultimately achieving power transmission to the drive wheels and driving the vehicle.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
