Description

Technical Field

[0001] This utility model relates to a CVT cooling system, and more particularly to a novel CVT cooling system. Background Technology

[0002] The CVT cooling system is a key auxiliary system that ensures the efficient and reliable operation of the continuously variable transmission (CVT). Its core function is to control the transmission temperature and prevent performance degradation or component damage caused by overheating.

[0003] In existing technologies, such as the CVT engine cooling air guide device disclosed in CN204610793U, an intake duct and an exhaust duct are added to the air inlet and outlet of the housing, and the height of the intake and outlet of the intake and exhaust ducts is higher than that of the air inlet and outlet of the housing, respectively. This can effectively prevent dust, mud, rainwater and other impurities from entering the housing, reduce the wear of belts and pulleys, extend the service life of belts and pulleys, effectively improve the transmission efficiency of the engine, and has a simple structure and is easy to maintain.

[0004] However, it also has some shortcomings. For example, since there is no air intake device, the amount of cooling air entering the chamber cannot be guaranteed. As a result, the cooling effect of the cooling air on the pulleys and belts cannot be guaranteed, which will reduce the service life of the pulleys and belts. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a new type of CVT cooling system with high cooling effect.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a novel CVT cooling system, including an engine body, in which a drive assembly and a transmission assembly are provided, and a transmission assembly is provided on the side wall of the engine body. The drive assembly controls the operation of the transmission assembly through the transmission assembly. The transmission assembly includes a mounting base, which is mounted on the side wall of the engine body; a first transmission wheel, which is rotatably mounted in the mounting base and connected to the drive assembly. The drive assembly is used to control the rotation of the first transmission wheel in the mounting base, and a fan blade is provided on the first transmission wheel; a second transmission wheel, which is rotatably mounted in the mounting base and connected to the transmission assembly. A transmission belt is sleeved on the second transmission wheel and the first transmission wheel; a protective cover, which is connected to the mounting base, and both the first and second transmission wheels are located inside the protective cover; an intake pipe, which is mounted on the side wall of the mounting base, with one end of the intake pipe on the mounting base near the first transmission wheel; and an exhaust pipe, which is mounted on the side wall of the protective cover, with one end of the exhaust pipe on the protective cover near the second transmission wheel.

[0007] A further preferred embodiment of this utility model is that multiple fan blades are evenly arranged on the outer wall of the second transmission wheel.

[0008] A further preferred embodiment of this utility model is that the protective cover and the mounting base are detachably connected by bolts.

[0009] A further preferred embodiment of this utility model is that the transmission belt is a CVT drive belt.

[0010] A further preferred embodiment of this utility model is that the fan blade and the second transmission wheel are integrally formed.

[0011] Compared with the prior art, the advantages of this utility model are that when the drive component drives the first transmission wheel to rotate, the fan blades mounted on the first transmission wheel also rotate. This generates suction inside the shroud. Because the air intake pipe is close to the first transmission wheel, when the first transmission wheel rotates, the cooling air outside the shroud can be drawn into the shroud by the air intake pipe. This ensures the amount of cooling air entering the shroud, thereby ensuring the cooling effect of the cooling air on the first and second transmission wheels and the transmission belt inside the shroud, and thus ensuring the service life of the first and second transmission wheels and the transmission belt.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0022] This embodiment mainly describes the structure of the novel CVT cooling system, as follows:

[0023] like Figures 1-6 As shown, a novel CVT cooling system includes an engine body 1, in which a drive assembly and a transmission assembly are disposed. A transmission assembly 2 is disposed on the side wall of the engine body 1, so that the drive assembly can control the operation of the transmission assembly through the transmission assembly 2.

[0024] The transmission assembly 2 includes a mounting base 21 mounted on the side wall of the engine body 1. A first transmission wheel 23 and a second transmission wheel 24 are rotatably disposed in the mounting base 21. The first transmission wheel 23 is connected to the drive assembly, so that when the drive assembly is working, it can control the first transmission wheel 23 to rotate in the mounting base 21. The second transmission wheel 24 is connected to the transmission assembly, and a transmission belt 25 is fitted on the first transmission wheel 23 and the second transmission wheel 24. In this way, when the first transmission wheel 23 rotates, it can drive the transmission assembly to work through the transmission belt 25.

[0025] To protect the first drive wheel 23, the second drive wheel 24, and the drive belt 25, a protective cover 22 is provided on the mounting base 21. This creates a new sealed space between the mounting base 21 and the protective cover 22 when they are connected. The first drive wheel 23 and the second drive wheel 24 are both located inside the protective cover 22. An air inlet pipe 211 communicating with the interior of the mounting base 21 is provided on the side wall of the mounting base 21, and an exhaust pipe 221 communicating with the interior of the protective cover 22 is provided on the side wall of the protective cover 22. The air inlet pipe 211 is located on the mounting base 21 near the first drive wheel 23, and the exhaust pipe 221 is located on the protective cover 22 near the second drive wheel 24. To allow cooling air from outside the protective cover 22 to enter the protective cover 22 through the air inlet pipe 211, a fan blade 26 is provided on the first drive wheel 23.

[0026] Thus, when the drive assembly drives the first transmission wheel 23 to rotate, the fan blade 26 mounted on the first transmission wheel 23 also rotates. This generates suction inside the shield 22. Because the air intake pipe 211 is close to the first transmission wheel 23, when the first transmission wheel 23 rotates, the cooling air outside the shield 22 can be drawn into the shield 22 by the air intake pipe 211. This ensures the amount of cooling air entering the shield 22, thereby ensuring the cooling effect of the cooling air on the first transmission wheel 23, the second transmission wheel 24, and the transmission belt 25 in the shield 22, and thus ensuring the service life of the first transmission wheel 23, the second transmission wheel 24, and the transmission belt 25.

[0027] Furthermore, in order to facilitate the discharge of high-temperature gas from the shield 22, multiple fan blades 27 are evenly arranged on the outer wall of the second transmission wheel 24. In this way, when the first transmission wheel 23 drives the second transmission wheel 24 to rotate via the transmission belt 25, the fan blades 27 installed on the second transmission wheel 24 will also rotate with the rotation of the second transmission wheel 24. Thus, when the fan blades 27 rotate, they can discharge the high-temperature gas from the shield 22 through the exhaust pipe 221.

[0028] Furthermore, to facilitate maintenance of the interior of the cover 22, the cover 22 and the mounting base 21 are detachably connected by bolts. At the same time, to ensure the reliability of the first transmission wheel 23 driving the second transmission wheel 24, the transmission belt 25 is a CVT drive belt. In this way, when the first transmission wheel 23 drives the second transmission wheel 24 to rotate through the transmission belt 25, the power transmission can be continuous and smooth.

[0029] Furthermore, in order to ensure the firm connection between the fan blade 27 and the first transmission wheel 23 and the second transmission wheel 24, the fan blade 27 is integrally formed with the first transmission wheel 23 or the second transmission wheel 24.

Therefore, they should not be construed as limitations on this utility model.

[0031] The novel CVT cooling system provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
