Description

Technical Field

[0001] The utility model relates to the technical field of dry clutches, in particular to a dry clutch and an engine. Background Art

[0002] The dry clutch has the advantages of simple structure, complete separation and high reliability. Therefore, it is widely used in vehicle shifting and speed changing. When a shifting operation needs to be performed, a force is applied to the clutch fork assembly through an actuator, and then to the release bearing seat, so that the engine is separated from or engaged with the transmission, thereby realizing the disconnection and transmission of power.

[0003] During the working process of the dry clutch, due to the different speeds of the engine and the transmission, friction needs to be generated to synchronize the two. This process will generate a large amount of heat on the flywheel and the pressure plate. As the temperature rises sharply, various components of the clutch such as the flywheel and the pressure plate will malfunction. In order to reduce the temperature, mainly by increasing the area of the pressure plate to accelerate the heat dissipation speed, but undoubtedly increases the overall volume, resulting in limited installation space. Summary of the Utility Model

[0004] In view of the deficiencies in the prior art, the utility model provides a dry clutch and an engine, which solve the problem that the clutch in the prior art increases the overall volume by increasing the area of the pressure plate to accelerate the heat dissipation speed, resulting in limited installation space.

[0023] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0024] As Figure 1 shown, an embodiment of the present invention provides a dry clutch, including a gland 1, a flywheel 6, and further including:

[0025] A mounting disk 2, disposed on the side of the gland 1 and coaxially arranged with the gland 1; and

[0026] A plurality of heat dissipation fins 3 are evenly arranged on the end face of the mounting disc 2 along the circumferential direction of the mounting disc 2, and a heat dissipation air duct 301 for air flow to pass through is formed between two adjacent heat dissipation fins 3.

[0027] In the embodiment of the present utility model, without affecting the original structure of the gland 1, by fitting and mounting the mounting disc 2 on the surface of the gland 1, each heat dissipation fin 3 on the mounting disc 2 is mounted on the side surface of the gland 1, so that the plurality of heat dissipation fins 3 and the gland 1 form an integral body, and there is no need to radially increase the heat dissipation area of the gland 1.

[0028] Secondly, while rotating as a whole, each heat dissipation fin 3 makes a circular motion with the gland 1 as the axis, and drives the surrounding air to flow through the formed heat dissipation air duct 301, so that the original static air flow is activated, thereby accelerating the heat exchange rate between the internal air flow and the outside world, effectively controlling the working temperature, reducing the risk of material fatigue, deformation or damage caused by overheating, and also helping to extend the service life of components such as the gland 1 and the flywheel 6, and ensuring the smoothness of vehicle gear shifting and power transmission.

[0029] Based on the above solution, as Figure 1 shown, the mounting disc 2 is provided with a plurality of mounting holes 4, and the mounting holes 4 penetrate through both end faces of the mounting disc 2 for bolt connection between the mounting disc 2 and the gland 1.

[0030] Under the action of the mounting holes 4, the mounting disc 2 and the gland 1 can be directly connected by bolts, which simplifies the installation steps and reduces the assembly difficulty. Moreover, the split design also allows for easy disassembly and reassembly during subsequent maintenance and replacement, reducing the maintenance cost and time. At the same time, the bolt connection can also ensure the close contact between the mounting disc 2 and the gland 1, guaranteeing the transmission of torque and maintaining the overall structural stability of the clutch.

[0031] Specifically, as Figure 1 shown, the mounting disc 2 is provided with a mounting seat 401 corresponding to the mounting holes 4, and the end of the mounting hole 4 penetrates through the mounting seat 401; the mounting seat 401 can provide a clear positioning point for convenient assembly, and the mounting seat 401 can increase the structural strength of the local area of the mounting hole 4, and can effectively prevent the deformation of the mounting disc 2 around the mounting holes 4 under high load conditions, indirectly ensuring the service life of the mounting disc 2.

[0032] Specifically, as Figure 3As shown in the figure, the mounting base 401 protrudes towards the other side along the axial direction of the mounting disc 2 to form a positioning portion 5. The mounting disc 2 is clamped to the gland 1 through the positioning portion 5. With the clamping of the positioning portion 5, during installation, the positioning portion 5 can ensure the accurate position of the mounting disc 2 relative to the gland 1, enabling the mounting disc 2 to be quickly and accurately docked with the gland 1, thereby improving the assembly accuracy. Moreover, the positioning portion 5 and the gland 1 combine to form a clamping portion. Since the mounting disc 2 is connected to the gland 1 by screws, the circumferential movement of the mounting disc 2 can also be limited through the positioning portion 5, thereby reducing the radial stress of the screws and ensuring the stability of the installation.

[0033] Specifically, as Figure 1 shown, the cross-section of the heat dissipation fins 3 is arc-shaped. The arc-shaped design can reduce the resistance of air flow, making it easier for air to pass through the air ducts between the heat dissipation fins 3, thereby enhancing the heat dissipation effect under natural convection or forced ventilation conditions. Moreover, the arc-shaped design helps to improve the durability of the heat dissipation fins 3 and extend their service life.

[0034] Based on the above solution, as Figure 2 shown, it further includes a fixing disc 601. The fixing disc 601 is provided with a spline hole 602 connected to the crankshaft. The spline connection method is used to connect the fixing disc 601 and the crankshaft, which improves the connection rigidity, ensures the effective transmission of torque, and the spline connection can automatically center, ensuring the precise alignment between the fixing disc 601 and the crankshaft, and can withstand a higher torque load, improving the overall safety.

[0035] As Figure 1 shown, the fixing disc 601 is also provided with a number of fixing holes 603 for bolts to pass through the fixing holes 603 and connect to the flywheel 6. The setting of the fixing holes 603 enables the fixing disc 601 and the flywheel 6 to be firmly connected together by bolts, improving the connection stability, ensuring the effective transmission of torque, and the split design enables easy disassembly and reassembly when maintenance or replacement of relevant components is required, reducing the maintenance cost and time.

[0036] The embodiment of the present utility model also proposes an engine, including the above dry clutch. The specific structure of the dry clutch refers to the above embodiment. Since this engine adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be elaborated one by one here.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
