Description

Technical Field

[0001] The utility model relates to the technical field of transmission belts, in particular to a speed-changing transmission belt for a snowmobile. Background Art

[0002] Snowmobiles are vehicles used to travel on snow. They move by rotating tracks and do not require specific roads when traveling. Snowmobiles generally have only one or two passengers and are often used for surveillance and rescue purposes at ski resorts. They are also widely used by amateur players for winter outdoor sports. Canada's Bombardier developed a rubber infinite track as a drive device in 1922, and the official product appeared in 1936.

[0003] The existing snowmobile speed transmission belt includes two sides, which are fixed by snapping. However, this fixation will cause the two single sides to lack sufficient structural strength. When the snowmobile is driving in a complex and changeable snowy environment, the transmission belt may not be able to withstand continuous high loads and strong impact forces. There is a potential risk of loose connection or even breakage, which may affect the performance of the snowmobile and may even pose a threat to the driver's safety. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a snowmobile speed-changing transmission belt to solve the technical problem of lack of sufficient structural strength on two single sides.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a snowmobile speed-changing transmission belt, comprising an outer belt and an inner belt, a fixing belt is arranged between the outer belt and the inner belt, a first through hole and a second through hole are respectively provided on the front and rear surfaces of the fixing belt, an upper clamping tooth is fixedly connected to the upper surface of the outer belt, and a lower clamping tooth is fixedly connected to the lower surface of the inner belt, vertical holes and horizontal holes are provided on the upper clamping teeth and the lower clamping teeth, a fixing pin is provided inside the vertical hole, and a reinforcing rod is fixedly connected inside the horizontal hole.

[0006] By adopting the above technical solution, the snowmobile speed-changing transmission belt can achieve a stable connection between the outer belt, the inner belt and the fixed belt. The structural strength of the transmission belt can be improved through the cooperation between the fixing pin and the first through hole and the second through hole, as well as the reinforcement effect of the strengthening rod.

[0007] Furthermore, the first through hole and the upper latching tooth are arranged opposite to each other, and the second through hole and the lower latching tooth are arranged opposite to each other.

[0008] By adopting the above technical solution, the relative arrangement of the first through hole and the upper latch tooth, and the relative arrangement of the second through hole and the lower latch tooth, the fixing pin can pass through the corresponding hole more conveniently and accurately, thereby realizing precise connection between the outer belt, the inner belt and the fixing belt.

[0009] Furthermore, a plurality of the first through holes and the upper latching teeth are provided, and the plurality of the first through holes and the upper latching teeth are evenly arranged at equal distances.

[0010] By adopting the above technical solution, a plurality of first through holes and upper clamping teeth that are evenly and equidistantly arranged ensure that the connection points between the outer belt and the fixed belt are evenly distributed, thereby avoiding stress concentration.

[0011] Furthermore, a plurality of the second through holes and the lower latching teeth are provided, and the plurality of the second through holes and the lower latching teeth are evenly arranged at equal distances.

[0012] By adopting the above technical solution, multiple equidistant and evenly arranged second through holes and lower teeth ensure that the connection points between the inner belt and the fixed belt are also evenly distributed, which helps to prevent problems such as excessive local stress or unstable connection caused by uneven connection points.

[0013] Furthermore, the fixing pin is rotatably connected to the reinforcing rod, one end of the fixing pin is provided with a cross slot, and the other end of the fixing pin is matched with the first through hole and the second through hole.

[0014] By adopting the above technical solution, the rotational connection design of the fixing pin and the reinforcing rod enables the fixing pin to rotate flexibly during installation, which is convenient for alignment with and insertion into the first through hole and the second through hole, thereby simplifying the installation steps, improving assembly efficiency, enhancing the connection strength between the two, and improving the overall installation strength.

[0015] Furthermore, the fixing belt is made of rubber.

[0016] By adopting the above technical solution, the fixing belt is made of high-strength rubber material with good elasticity and wear resistance, so that the fixing belt can maintain stable performance during long-term use and is not prone to breakage or damage.

[0017] Furthermore, one side surface of the fixing belt is in contact with the outer belt, and an adhesive layer is provided between the fixing belt and the outer belt.

[0018] By adopting the above technical solution, the adhesive layer provided between the fixing belt and the outer belt can effectively enhance the adhesion between the two, ensuring that they can fit tightly during use and are not prone to relative displacement.

[0019] Furthermore, the other side surface of the fixing belt is in contact with the inner belt, and a rubber layer is provided between the fixing belt and the inner belt.

[0020] By adopting the above technical solution and providing a glue layer between the fixing belt and the inner belt, the bonding strength and stability between the two parts can be enhanced.

[0021] Furthermore, the upper and lower latch teeth are both made of wear-resistant rubber.

[0022] By adopting the above technical solution, the upper and lower teeth are made of wear-resistant rubber material, which significantly improves the wear resistance of the teeth, allowing the transmission belt to maintain stable transmission efficiency during long-term use and reducing the performance degradation problem caused by tooth wear.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] 1. The utility model can ensure the stable connection between the outer belt, the inner belt and the fixed belt by setting the fixing pin and the reinforcing rod, so as to prevent the transmission belt from loosening or falling off during use. The internal reinforcing rod cooperates with the fixing pin to play the role of reinforcing ribs, which can significantly improve the overall structural strength of the transmission belt, making it more durable and able to withstand a greater workload, thereby improving the service life and stability of the transmission belt;

[0025] 2. The utility model forms a stable transmission belt structure by arranging an outer belt, an inner belt, a fixed belt and a fixed pin. A specific connection method is adopted, that is, the fixed pin is inserted into the corresponding through hole and rotated to complete the connection, thereby ensuring the close fit and stability of various parts of the transmission belt. By rotating the fixed pin and aligning it with the corresponding through hole, the connection between the outer belt, the inner belt and the fixed belt can be easily completed, thereby simplifying the installation and disassembly process and improving work efficiency.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure.

[0033] A snowmobile speed transmission belt, such as Figure 1-Figure 4 As shown, it includes an outer belt 1 and an inner belt 2, a fixing belt 3 is arranged between the outer belt 1 and the inner belt 2, and the front and rear surfaces of the fixing belt 3 are respectively provided with a first through hole 10 and a second through hole 11, the upper surface of the outer belt 1 is fixedly connected with an upper clamping tooth 4, and the lower surface of the inner belt 2 is fixedly connected with a lower clamping tooth 5, and the upper clamping tooth 4 and the lower clamping tooth 5 are both provided with a vertical hole 6 and a horizontal hole 7, a fixing pin 8 is arranged inside the vertical hole 6, and a reinforcing rod 9 is fixedly connected inside the horizontal hole 7. The snowmobile speed change transmission belt can realize a stable connection between the outer belt 1, the inner belt 2 and the fixing belt 3. Through the cooperation of the fixing pin 8 with the first through hole 10 and the second through hole 11, and the reinforcement effect of the reinforcing rod 9, the structural strength of the transmission belt can be improved. At the same time, the service life and stability of the transmission belt are improved, so that it can better adapt to harsh working environments such as snowmobiles, reduce the risk of failure caused by damage to the transmission belt, and provide a strong guarantee for the normal operation of the snowmobile.

[0034] See also Figure 1 , Figure 2 and Figure 3 The first through hole 10 and the upper latch tooth 4 are arranged relative to each other, and the second through hole 11 and the lower latch tooth 5 are arranged relative to each other. The relative arrangement of the first through hole 10 and the upper latch tooth 4, and the relative arrangement of the second through hole 11 and the lower latch tooth 5, enable the fixing pin 8 to pass through the corresponding holes more conveniently and accurately, thereby realizing the precise connection between the outer belt 1, the inner belt 2 and the fixing belt 3. At the same time, this relative position design also simplifies the installation process, improves assembly efficiency, and reduces operation difficulty, thereby helping to reduce production costs and improve product quality.

[0035] See also Figure 1 , Figure 2 and Figure 3 There are multiple first through holes 10 and upper teeth 4, and the multiple first through holes 10 and upper teeth 4 are evenly arranged at equal intervals. The multiple evenly arranged first through holes 10 and upper teeth 4 ensure that the connection points between the outer belt 1 and the fixed belt 3 are evenly distributed, avoiding stress concentration. At the same time, the carrying capacity and stability of the transmission belt are improved, so that it can better disperse the load during operation and reduce the risk of damage caused by local overload.

[0036] See also Figure 1 , Figure 2 and Figure 3 There are multiple second through holes 11 and lower latch teeth 5, and the multiple second through holes 11 and lower latch teeth 5 are evenly arranged at equal distances. The multiple evenly arranged second through holes 11 and lower latch teeth 5 ensure that the connection points between the inner belt 2 and the fixed belt 3 are also evenly distributed, which helps to prevent problems such as excessive local stress or unstable connection caused by uneven connection points. At the same time, the design of evenly arranged even distances also makes the mechanical properties of the entire transmission belt more balanced, thereby improving its overall structural stability and durability.

[0037] See also Figure 4 The fixing pin 8 and the reinforcing rod 9 are rotatably connected, a cross groove 12 is provided at one end of the fixing pin 8, and the other end of the fixing pin 8 is adapted to the first through hole 10 and the second through hole 11. The rotatable connection design of the fixing pin 8 and the reinforcing rod 9 enables the fixing pin 8 to be flexibly rotated during installation, so as to be easily aligned with and inserted into the first through hole 10 and the second through hole 11, thereby simplifying the installation steps, improving the assembly efficiency, enhancing the connection strength between the two, and improving the overall installation strength. At the same time, the cross groove 12 design at one end of the fixing pin 8 provides a convenient operating interface during the installation and disassembly process, so that the staff can easily perform the rotation operation using the corresponding tools, further improving the convenience and efficiency of the installation.

[0038] See also Figure 1 , Figure 2 and Figure 3 The material of the fixing belt 3 is rubber. The fixing belt 3 adopts high-strength rubber material with good elasticity and wear resistance, so that the fixing belt 3 can maintain stable performance during long-term use and is not prone to breakage or damage. At the same time, the rubber material also has good oil resistance, water resistance, acid and alkali resistance and other properties, which enables the fixing belt 3 to maintain stable performance in harsh working environments, further improving the durability and reliability of the transmission belt.

[0039] See also Figure 1 , Figure 2 and Figure 3 One side surface of the fixed belt 3 is in contact with the outer belt 1, and an adhesive layer is arranged between the fixed belt 3 and the outer belt 1. The adhesive layer arranged between the fixed belt 3 and the outer belt 1 can effectively enhance the adhesion between the two, ensuring that they can fit tightly during use and are not prone to relative displacement. At the same time, the adhesive layer can also improve the sealing performance of the transmission belt, prevent external impurities and moisture from invading, thereby ensuring the stable operation of the transmission belt.

[0040] See also Figure 1 , Figure 2 and Figure 3The other side surface of the fixed belt 3 is in contact with the inner belt 2, and an adhesive layer is arranged between the fixed belt 3 and the inner belt 2. The adhesive layer is arranged between the fixed belt 3 and the inner belt 2 to enhance the bonding strength and stability between the two parts. At the same time, the adhesive layer further improves the overall sealing of the transmission belt, effectively prevents the penetration of external impurities and moisture, and ensures the stable operation and long-term reliability of the transmission belt.

[0041] See also Figure 1 , Figure 2 and Figure 3 The upper and lower teeth 4 and 5 are both made of wear-resistant rubber material. Through the above technical solution, the upper and lower teeth 4 and 5 are made of wear-resistant rubber material, which significantly improves the wear resistance of the teeth, so that the transmission belt can maintain a stable transmission efficiency during long-term use, and reduces the performance degradation problem caused by tooth wear. At the same time, the wear-resistant rubber material also has good elasticity and impact resistance, which helps to reduce vibration and noise during transmission and improve the overall use effect of the transmission belt.

[0042] The implementation principle of the utility model is as follows: first, the plurality of fixing pins 8 on the inner belt 2 are rotated so that the bottom of the fixing pin 8 is opposite to the second through hole 11, and then the fixing pin 8 is inserted into the second through hole 11, and then the fixing pin 8 is rotated through the cross groove 12 so that the bottom of the fixing pin 8 can be fixedly connected with the fixing belt 3, thereby completing the connection between the inner belt 2 and the fixing belt 3;

[0043] Then, the plurality of fixing pins 8 on the outer belt 1 are rotated so that the bottom of the fixing pin 8 is opposite to the first through hole 10, and then the fixing pin 8 is inserted into the first through hole 10, and then the fixing pin 8 is rotated through the cross groove 12 so that the bottom of the fixing pin 8 can be fixedly connected with the fixing belt 3, thereby completing the connection between the outer belt 1 and the fixing belt 3;

[0044] When in use, the internal reinforcing rod 9 and the fixing pin 8 act as reinforcing ribs to improve the structural strength of the transmission belt.
