Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and in particular to a slip clutch with seamless shifting. Background Technology

[0002] As a key component of mechanical transmission systems, the clutch plays a crucial role in modern industry, especially in the development of vehicles such as automobiles and motorcycles. Its performance directly affects vehicle starting, gear shifting smoothness, and power transmission efficiency. With technological advancements and ever-increasing demands on vehicle performance, vehicle power systems are constantly being upgraded, with engine power and torque continuously increasing. This places more stringent requirements on the clutch, demanding not only the ability to reliably transmit greater power but also ensuring comfortable operation. Traditional clutch structures are no longer sufficient to meet these growing needs, urgently requiring a more advanced and intelligent clutch technology to drive industry development.

[0003] In the past, various technologies have been employed in the industry to address clutch-related issues. Among these, multi-plate wet clutches are a common solution. These clutches use oil for cooling and lubrication, effectively reducing wear between the friction plates and extending the clutch's lifespan. The oil also provides a buffering effect, resulting in smoother clutch engagement. In addition, there are traditional spring-loaded clutches, which use the preload of a spring to press the driving and driven plates together to transmit torque. This structure is simple to understand and relatively inexpensive, making it widely used in cost-sensitive applications. Finally, there are electromagnetic clutches, which use electromagnetic force to control clutch engagement and disengagement, offering advantages such as fast response and high control precision.

[0004] However, existing clutch technologies have significant drawbacks. Traditional spring-loaded clutches have a fixed spring preload, which cannot be automatically adjusted according to actual operating conditions. Under high loads, the spring force may be insufficient to ensure reliable contact between the driving and driven plates, leading to clutch slippage and affecting power transmission efficiency. Conversely, under low loads, the spring may be over-compressed, increasing unnecessary energy loss and making clutch disengagement difficult, requiring greater operating force. This not only reduces vehicle reliability but also affects driver comfort. Utility Model Content

[0005] This application provides a seamless shifting slip clutch, which adopts a slip clutch with a sliding structure to achieve the effect of automatically adjusting the friction plate clamping force and reducing the clutch disengagement operation force.

[0006] This application provides a seamless shifting slipper clutch, which adopts the following technical solution:

[0007] A seamless shifting slipper clutch includes a clutch drive hub, a clutch driven hub, and a slipper pressure plate. A drive plate is provided on one side of the clutch drive hub, a driven plate is provided on one side of the clutch driven hub, and a first slipper drive plate, a second slipper drive plate, and a slipper driven plate are provided on one side of the slipper pressure plate. The slipper driven plate is disposed between the first slipper drive plate and the second slipper drive plate. A slipper pressure plate is provided on one side of the second slipper drive plate. Three sets of sliding structures are provided between the slipper pressure plate and the clutch driven hub.

[0008] By adopting the above technical solution, this utility model designs a seamless shifting sliding clutch. In use, the active and driven plates enable torque transmission, and the sliding driven plate, placed between two sliding active plates, enables force transmission. During torque transmission, the sliding pressure plate is compressed inward due to resistance, and the wedge-shaped contact further compresses the active and driven plates, reducing the demand on spring force. When relative slippage occurs, the sliding pressure plate is subjected to the force of relative slippage, increasing the overall pressure and further reducing the demand on spring force, thus reducing the force required to pull the handle when the clutch disengages. When the clutch shows a tendency to slip, the active and driven plates automatically tighten through the wedge-shaped contact, reducing slippage.

[0009] Preferably, a retaining tooth is provided between the sliding pressure plate and the sliding driven piece, and an internal tooth is provided on the sliding driven piece. The retaining tooth on the sliding pressure plate and the internal tooth of the sliding driven piece are engaged and connected with each other.

[0010] By adopting the above technical solution, the sliding pressure plate and the sliding driven plate can effectively transmit force during use, ensuring the stability of clutch torque transmission and thus enhancing clutch reliability.

[0011] Preferably, the clutch drive hub is provided with a second retaining tooth, which engages with the outer teeth of the second sliding drive plate.

[0012] By adopting the above technical solution, force transmission between the clutch drive hub and the sliding drive plate can be realized during use, ensuring that power is effectively transmitted from the clutch drive hub to other components through the sliding drive plate, thus guaranteeing the normal operation of the clutch.

[0013] Preferably, the sliding structure includes a first wedge surface and a second wedge surface disposed on the clutch driven hub, and a third wedge surface and a fourth wedge surface disposed on the sliding pressure plate. The first wedge surface and the third wedge surface slide together, and the second wedge surface and the fourth wedge surface slide relative to each other.

[0014] By adopting the above technical solution, during use, when torque is transmitted, the sliding pressure plate is compressed inward due to the interaction of power and resistance, and the wedge surface cooperation makes the driving plate and driven plate more compact, reducing the demand for spring force; when relative slippage occurs, the sliding pressure plate moves downward under the force of relative slippage, increasing the overall pressure, further reducing the demand for spring force, and at the same time reducing the operating force required when the clutch is disengaged; when the clutch shows a tendency to slip, the wedge surface cooperation automatically presses the driving plate and driven plate together, reducing slippage.

[0015] Preferably, the first wedge surface and the third wedge surface are arranged at an inclined angle relative to each other, and the second wedge surface and the fourth wedge surface are arranged at an inclined angle relative to each other.

[0016] By adopting the above technical solution, the wedge surfaces that are set at an inclined angle can better cooperate and slide during use, and when the clutch shows a tendency to slip, the slippage torque can be more effectively converted into axial force.

[0017] Preferably, a pressure plate is provided on one side of the sliding pressure plate, and the sliding pressure plate and the pressure plate are connected by a spring structure.

[0018] By adopting the above technical solution, when the clutch is in operation, the spring structure, together with the sliding pressure plate and the pressure plate, can play a certain role in buffering and elastic support when the sliding pressure plate moves under the action of the sliding structure, which can help the sliding pressure plate to better complete the pressing or disengaging action; when the clutch needs to be disengaged, the spring structure and the sliding structure work together to further reduce the operating force required for disengagement.

[0019] Preferably, the clutch driven hub is provided with a fixing rod, the fixing rod is provided with a threaded groove, the threaded groove is threadedly connected to a bolt, and the pressure plate is sleeved on the bolt, and the bolt is used to limit the displacement distance of the pressure plate.

[0020] By adopting the above technical solution, during use, a fixing rod is installed on the driven hub of the clutch, and a threaded groove is provided in the rod and threadedly connected to the bolt. The pressure plate is sleeved on the bolt, which can limit the displacement distance of the pressure plate and further ensure the stable operation of the clutch.

[0021] In summary, this application has the following beneficial effects:

[0022] 1. The present invention provides a seamless shifting sliding clutch that reduces the need for spring force, eliminating the need for spring force during clutch operation and reducing the pulling force required for disengagement;

[0023] 2. The seamless shifting sliding clutch designed in this utility model can reduce the force required to pull the handle when the clutch is disengaged, and reduce the disengagement force;

[0024] 3. The present invention provides a seamless shifting sliding clutch that can automatically press together the driving and driven plates through wedge-shaped contact when the clutch tends to slip, thereby reducing slippage. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0031] This utility model discloses a slip clutch with seamless shifting, such as Figures 1 to 4As shown, the clutch includes a clutch drive hub 1, a clutch driven hub 2, and a sliding pressure plate 3. The clutch drive hub 1 is provided with a drive plate 4 on one side, the clutch driven hub 2 is provided with a driven plate 5 on one side, and the sliding pressure plate 3 is provided with a first sliding drive plate 64, a second sliding drive plate 74, and a sliding driven plate 85 on one side, with the sliding driven plate 85 positioned between the first sliding drive plate 64 and the second sliding drive plate 74. The sliding pressure plate 3 is provided on one side of the second sliding drive plate 74. Three sets of sliding structures 11 are provided between the sliding pressure plate 3 and the clutch driven hub 2, which achieves the beneficial effects of automatically adjusting the clamping force, reducing the separation force, and reducing slippage. This is because during torque transmission, there is a resistance interaction force between the power and the sliding pressure plate 3, which will compress inward. The wedge surface of the sliding structure 11 makes the whole more compact, reducing the demand for spring force. When relative slippage occurs, the relative slippage force on the sliding pressure plate 3 presses the sliding pressure plate 3 downward, increasing the overall pressure and further reducing the demand for spring force. At the same time, it reduces the force of the lever when disengaging. When the clutch shows a tendency to slip, the wedge surface automatically presses the driving plate 4 and the driven plate 5 together to reduce slippage.

[0032] Specifically, the clutch drive hub 1 includes a hub body and a second locking tooth 10 disposed thereon. The hub body is typically made of a high-strength metal material, such as alloy steel, to ensure it can withstand large torques. Its shape is generally disc-shaped with a central shaft hole for connection to the power input shaft. The second locking teeth 10 are distributed on the circumferential surface of the hub body, and their shape can be rectangular, trapezoidal, etc., made of the same material as the hub body. The second locking teeth 10 engage with the external teeth of the sliding drive plate 4. This engagement can be a clearance fit to ensure accurate power transmission from the drive hub to the sliding drive plate 4 during power transmission. Alternatively, the second locking teeth 10 can also be connected to the sliding drive plate 4 in a spline configuration, which offers better centering accuracy and load-bearing capacity.

[0033] Specifically, the clutch driven hub 2 includes a hub body, a fixing rod 18, a first wedge surface 12, and a second wedge surface 13. The hub body is also made of high-strength metal material and has a similar shape to the clutch driving hub 1. The fixing rod 18 is mounted on the clutch driven hub 2 and is typically cylindrical with internal threaded grooves for engaging with bolts 19. The function of the fixing rod 18 is to limit the displacement distance of the pressure plate 16 via the bolts 19. The first wedge surface 12 and the second wedge surface 13 are positioned at specific locations on the clutch driven hub 2. The surfaces of the wedge surfaces require precision machining to ensure good sliding cooperation with the third wedge surface 14 and the fourth wedge surface 15 on the sliding pressure plate 3. The inclination angle of the wedge surfaces is determined according to actual design requirements and is generally taken within a certain range to achieve the best clamping force adjustment effect. Alternatively, the fixing rod 18 can be fixed to the hub body by welding or manufactured as a single piece; the shape of the wedge surface can be optimized according to different mechanical models.

[0034] Specifically, the sliding pressure plate 3 includes a plate body, locking teeth, a third wedge surface 14, a fourth wedge surface 15, a pressure plate 16, and a spring structure 17. The plate body is generally made of a lightweight and high-strength metal material, such as aluminum alloy, to reduce rotational inertia. The locking teeth are located on the side of the plate body that contacts the sliding driven plate 85, and their shape and size match the internal teeth of the sliding driven plate 85, with a matching method similar to the matching of the second locking teeth 10 and the external teeth of the sliding driving plate 4. The third wedge surface 14 and the fourth wedge surface 15 are located on the side of the plate body opposite to the clutch driven hub 2, and slide in cooperation with the first wedge surface 12 and the second wedge surface 13. The pressure plate 16 is located on one side of the plate body and is connected to the plate body through the spring structure 17. The spring structure 17 can be a helical spring, with its elastic coefficient selected according to design requirements to provide appropriate preload. When relative sliding occurs in the sliding pressure plate 3, the spring structure 17 can buffer and assist in adjusting the clamping force. Alternatively, spring structure 17 can be a disc spring, which has the advantages of small footprint and high load-bearing capacity.

[0035] Specifically, the first sliding active plate 64 and the second sliding active plate 74 are typically made of wear-resistant metal materials, such as carbon steel. They are disc-shaped with external teeth distributed on their circumferential surface. The sliding driven plate 85 also uses a similar wear-resistant material, with internal teeth distributed on its inner circumferential surface. Their mating mechanism allows for efficient power transmission between the active plate 4 and the driven plate 5.

[0036] The implementation principle of this embodiment is as follows: This seamless shifting slipper clutch, through the unique slipper structure 11 and the cooperation of various components, solves the problem that the spring preload of traditional clutches is fixed and cannot be automatically adjusted according to working conditions. During power transmission, the wedge-shaped cooperation of the slipper structure 11 automatically adjusts the clamping force according to working conditions, reducing dependence on spring force and lowering the operating force required for disengagement. At the same time, it can automatically clamp when the clutch shows a tendency to slip, reducing slippage and improving the reliability and operating comfort of the clutch. Compared with traditional clutches, this represents a significant improvement and enhancement.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
