Description

Technical Field

[0001] The utility model relates to the technical field of automotive spline hubs, and specifically relates to an anti-damage structure for an automotive spline hub. Background Technique

[0002] An automotive spline hub is a key mechanical transmission component, mainly used in the transmission system of heavy trucks, especially playing an important role when connecting the universal joint fork and the shaft fork in the drive shaft assembly. Simply put, a spline hub is a hub connected to another component (such as a gear, a shaft, etc.) through a spline shaft, and it undertakes the important task of transmitting mechanical torque.

[0003] During long-term vehicle operation or under high-load working conditions, heat generated inside the spline hub due to mechanical friction and power transmission accumulates rapidly. Since the existing spline hubs lack an effective heat dissipation mechanism, it is difficult for this heat to dissipate quickly. This problem of insufficient heat dissipation directly leads to the deterioration of the working environment of the spline hub. The increase in internal temperature not only accelerates the aging and wear of materials, but also easily causes heat stress concentration, which in turn has an adverse impact on the structural strength and durability of the spline hub. In the long run, the spline hub may be damaged due to being unable to withstand high temperature and high pressure, affecting the overall performance and stability of the transmission system, and even potentially causing safety hazards. Therefore, we propose an anti-damage structure for an automotive spline hub. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-damage structure for an automotive spline hub to solve the problem proposed in the above background technique that due to the lack of an effective heat dissipation mechanism in the existing spline hubs, it is difficult for this heat to dissipate quickly. This problem of insufficient heat dissipation directly leads to the deterioration of the working environment of the spline hub. The increase in internal temperature not only accelerates the aging and wear of materials, but also easily causes heat stress concentration, which in turn has an adverse impact on the structural strength and durability of the spline hub. In the long run, the spline hub may be damaged due to being unable to withstand high temperature and high pressure, affecting the overall performance and stability of the transmission system, and even potentially causing safety hazards.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-damage structure for an automotive spline hub, including a spline hub body. A fixed cylinder is fixedly installed on the inner wall of the spline hub body. An internal spline is fixedly connected to the inner wall of the fixed cylinder. Heat dissipation fins are fixedly installed on the outer wall of the spline hub body. A groove is opened at the center of one end of the internal spline. A thermal grease block is fixedly installed on the inner wall of the groove. Heat conduction channels are opened on the inner walls of both the fixed cylinder and the spline hub body. A heat conduction copper wire is fixedly connected to the center of one end of the thermal grease block.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The anti-damage structure of the automotive spline hub, through the design of heat dissipation fins, grooves, thermal grease blocks, heat conduction channels and heat conduction copper wires, effectively increases the heat dissipation area of the spline hub body through the carefully designed heat dissipation fins, enabling the heat generated during vehicle operation to be dissipated into the air more quickly, thereby significantly reducing the internal temperature of the spline hub. At the same time, the thermal grease blocks fixed in the grooves, as efficient heat conduction media, can quickly absorb and transfer the heat generated by friction of the internal spline, further improving the heat dissipation efficiency. In addition, the setting of the heat conduction channels enables heat to flow efficiently between the spline hub body and the inside of the fixed cylinder. Especially its layout of being connected in pairs ensures that the heat can be evenly distributed and quickly exported, avoiding the occurrence of local overheating. The heat conduction copper wires, as the bridge connecting the heat conduction channels and the heat dissipation fins, not only enhance the continuity of heat conduction but also ensure that the heat can be directly and efficiently transferred to the heat dissipation fins and finally dissipated into the external environment, preventing the automotive spline hub from being damaged due to overheating and extending its service life.

[0013] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] Please refer to Figures 1-4, the utility model provides a technical solution: an anti-damage structure for an automotive spline hub, including a spline hub body 1, a fixed cylinder 2 is fixedly installed on the inner wall of the spline hub body 1, an internal spline 3 is fixedly connected to the inner wall of the fixed cylinder 2, heat dissipation fins 4 are fixedly installed on the outer wall of the spline hub body 1, a groove 7 is opened at the center of one end of the internal spline 3, a thermal grease block 8 is fixedly installed on the inner wall of the groove 7, heat conduction channels 9 are opened on the inner walls of both the fixed cylinder 2 and the spline hub body 1, and a heat conduction copper wire 10 is fixedly connected to the center of one end of the thermal grease block 8.

[0015] The number of internal splines 3 is several, and several internal splines 3 are arranged in an annular equidistant distribution. This layout not only enhances the load-bearing capacity and transmission stability of the spline hub, but also enables heat to be evenly distributed among multiple internal splines 3, which is beneficial to overall heat dissipation and reduces the risk of performance degradation or damage caused by local overheating.

[0016] A flange 5 is fixedly connected to the rear end of the outer wall of the spline hub body 1, and several mounting holes 6 are opened on the front surface of the flange 5, which facilitates the quick and stable connection of the spline hub body 1 with other components. The setting of the mounting holes 6 provides various mounting methods and flexibility, ensuring that the spline hub body 1 can be accurately and reliably integrated into the automotive transmission system.

[0017] The outer wall of the thermal grease block 8 is in contact with the inner wall of the groove 7. This contact method ensures that the thermal grease block 8 can efficiently transfer the heat generated by the internal spline 3 to the heat dissipation fins 4, further improving the heat dissipation efficiency.

[0018] The heat conduction channels 9 provided inside the spline hub body 1 and the fixed cylinder 2 correspond to several internal splines 3 one by one, and the heat conduction channels 9 provided inside the spline hub body 1 and the fixed cylinder 2 are connected in pairs to provide a heat conduction space for the heat conduction copper wire 10.

[0019] One end of the heat conduction copper wire 10 sequentially penetrates through the outer walls of the two heat conduction channels 9 and is fixedly connected to the inner wall of the heat dissipation fins 4. As an efficient heat conduction element, the high heat conduction performance of the heat conduction copper wire 10 enables heat to be quickly transferred from the heat conduction channel 9 to the heat dissipation fins 4, further enhancing the heat dissipation effect.

[0020] Working principle: The working principle of the anti-damage structure of the automotive spline hub is mainly reflected in its unique heat conduction and dissipation mechanism. During vehicle operation, the internal spline 3, as a transmission component, generates a large amount of heat due to friction. This heat is first quickly absorbed by the thermal grease block 8 in the central groove 7 at one end of the internal spline 3. With its excellent thermal conductivity, the thermal grease block 8 efficiently transfers the heat to the inner wall of the heat dissipation fins 4 in close contact with it. At the same time, to further enhance the heat dissipation effect, heat conduction channels 9 corresponding one by one to the internal spline 3 are designed inside the spline hub body 1 and the fixed cylinder 2, and these heat conduction channels 9 are connected in pairs to form an efficient heat circulation network. As a key component in this network, one end of the heat conduction copper wire 10 is fixedly connected to the thermal grease block 8, and the other end penetrates through the outer walls of the two heat conduction channels 9 and is finally fixedly connected to the inner wall of the heat dissipation fins 4. In this way, the heat conduction copper wire 10 can not only quickly conduct the heat absorbed by the thermal grease block 8 into the heat conduction channels 9, but also, through the connectivity of the heat conduction channels 9, disperse the heat throughout the spline hub structure, further reducing local high temperatures. As the heat is continuously transferred and dispersed, the heat dissipation fins 4, as the final heat dissipation component, can effectively dissipate the absorbed heat to the surrounding environment through their large heat dissipation surfaces, thereby keeping the spline hub body 1 and the internal spline 3 within an appropriate operating temperature range. This design not only extends the service life of the spline hub but also improves the overall performance and reliability of the automotive transmission system.

[0021] In summary: For the anti-damage structure of the automotive spline hub, through the design of the heat dissipation fins 4, grooves 7, thermal grease blocks 8, heat conduction channels 9, and heat conduction copper wires 10, the anti-damage structure of the automotive spline hub effectively increases the heat dissipation area of the spline hub body 1 through the carefully designed heat dissipation fins 4, enabling the heat generated during vehicle operation to be dissipated into the air more quickly, thus significantly reducing the internal temperature of the spline hub. At the same time, the thermal grease block 8 fixed in the groove 7, as an efficient heat conduction medium, can quickly absorb and transfer the heat generated by the friction of the internal spline 3, further improving the heat dissipation efficiency. In addition, the setting of the heat conduction channels 9 enables heat to flow efficiently inside the spline hub body 1 and the fixed cylinder 2. Especially its layout of being connected in pairs ensures that the heat can be evenly distributed and quickly exported, avoiding the occurrence of local overheating. The heat conduction copper wire 10, as a bridge connecting the heat conduction channels 9 and the heat dissipation fins 4, not only enhances the continuity of heat conduction but also ensures that the heat can be directly and efficiently transferred to the heat dissipation fins 4 and finally dissipated to the external environment, preventing the automotive spline hub from being damaged due to overheating and extending its service life.
