Abstract
Description
Technical Field
[0001] This utility model relates to the field of clutch technology, and in particular to a sliding assisted clutch. Background Technology
[0002] The clutch is an important component in the automotive transmission system. It is located between the engine and the transmission, and its main function is to transmit or disconnect power from the engine to the transmission. The main types include dry clutches, wet clutches, dual-clutch transmissions, and torque converters.
[0003] Slippery assisted clutches are mainly used in motorcycles, especially large-displacement and high-performance motorcycles, to improve their stability and handling under high-speed and aggressive driving conditions. This clutch design helps reduce rear wheel instability caused by excessive engine braking force, while also making clutch operation easier and improving the driving experience. For example, a prior application with publication number CN217207417U discloses a slippery assisted clutch in which a cam and a slide are engaged or disengaged by a coil spring. However, the cam and slide make surface contact, resulting in high friction, especially in small-displacement engines, leading to a small contact area and difficulty in effectively transmitting power.
[0004] Therefore, those skilled in the art are dedicated to developing a sliding-assisted clutch that, under the same elastic force, increases the contact area between the boss and the slide, thereby improving power transmission efficiency. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a sliding power-assisted clutch, which, under the same elastic force, helps to increase the contact area between the boss and the slide, thereby improving the power transmission efficiency.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0007] A slipper-assisted clutch, comprising
[0008] A central sleeve assembly, wherein the central sleeve assembly has a plurality of spaced protrusions arranged along the circumferential direction;
[0009] The pressure plate assembly is connected to the center sleeve assembly via a connecting assembly. The pressure plate assembly and the center sleeve assembly are alternately and overlappingly arranged with active transmission plates and driven transmission plates. The pressure plate assembly is equipped with a cover plate and a slide table that mates with the boss. A sliding assembly is installed between the boss and the slide table.
[0010] A reset spring passes through the pressure plate assembly and its two ends abut against the center sleeve assembly and the cover plate, respectively. A limit assembly is also installed between the reset spring and the cover plate.
[0011] The beneficial effects of adopting the above scheme are: a sliding component is installed between the boss and the slide, which reduces the sliding friction between the two when the boss and the slide slide relative to each other. Under the same elastic force, it helps to increase the contact area between the cam and the slide groove and improve the power transmission efficiency.
[0012] The limiting component prevents the return spring from twisting and deforming, while also reducing the friction between the return spring and the cover plate, thus extending the service life of the return spring.
[0013] Based on the above technical solution, the present invention can be further improved as follows.
[0014] Furthermore, the slide table is an inclined surface, and the sliding assembly includes a sliding groove disposed on the slide table. A rolling wheel is installed in the sliding groove via a rotating rod, and the outer edge of the rolling wheel and the slide table surface abut against the boss surface.
[0015] The beneficial effect of adopting the above-mentioned further solution is that when the boss and the slide move relative to each other, the outer edge of the rolling wheel slides along the surface of the boss, reducing the sliding friction between the boss and the slide.
[0016] Furthermore, the boss is provided with a rolling groove for the rolling wheel to roll, the outer edge of the rolling wheel abuts against the inner wall of the rolling groove, and the surface of the boss abuts against the surface of the slide.
[0017] The beneficial effect of adopting the above-mentioned further solution is that the rolling groove is used to limit the rolling path of the rolling wheel.
[0018] Furthermore, the pressure plate assembly is also equipped with a locking pin to prevent the rotating rod from retracting.
[0019] The beneficial effect of adopting the above-mentioned further solution is that the locking pin prevents the rotating rod from falling out.
[0020] Furthermore, the limiting component includes a limiting post, which is engaged within the reset spring. A connecting plate is connected to the end of the limiting post, and the end face of the connecting plate abuts against the end face of the reset spring. A positioning part is installed on the connecting plate on the side opposite to the limiting post, and the positioning part abuts against the end face of the cover plate.
[0021] The beneficial effects of adopting the above-mentioned further solution are: the positioning part abuts against the cover plate, reducing the friction between the return spring and the cover plate, and at the same time reducing the torsional force on the return spring.
[0022] Furthermore, the positioning part is hemispherical.
[0023] The beneficial effect of adopting the above-mentioned further solution is that the positioning part is hemispherical, which reduces the contact area between the positioning part and the cover plate.
[0024] Furthermore, the limiting component includes a fixing post, which is fixedly connected to the cover plate. The fixing post passes through the return spring and its length is two-thirds to four-fifths of the length of the return spring.
[0025] The beneficial effect of adopting the above-mentioned further solution is that the fixed column reduces the torsional force received by the return spring.
[0026] Furthermore, the connecting assembly includes a connecting bolt, and the central sleeve assembly has a connecting stud that mates with the connecting bolt.
[0027] The beneficial effect of adopting the above-mentioned further solution is that the connection bolts and connection studs facilitate the connection of the center sleeve assembly and the pressure plate assembly.
[0028] Furthermore, a gear disk is also installed on the central sleeve assembly.
[0029] The beneficial effect of adopting the above-mentioned further solution is that the gear disk is used to transmit power. Attached Figure Description

[0038] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0039] In the description of this invention, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "inner," "outer," "circumferential," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0040] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0041] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a slip-assisted clutch includes
[0043] The central sleeve assembly 1 has a plurality of spaced protrusions 2 along the circumferential direction;
[0044] The pressure plate assembly 3, the center sleeve assembly 1 and the pressure plate assembly 3 are connected by the connecting assembly 4. The pressure plate assembly 3 and the center sleeve assembly 1 are arranged with an alternating active transmission plate 5 and a driven transmission plate 6. The pressure plate assembly 3 is equipped with a cover plate 7. The pressure plate assembly 3 is provided with a slide 8 that cooperates with the boss 2. A sliding assembly 9 is installed between the boss 2 and the slide 8.
[0045] The reset spring 10 passes through the pressure plate assembly 3 and its two ends abut against the center sleeve assembly 1 and the cover plate 7 respectively. A limit assembly 11 is also installed between the reset spring 10 and the cover plate 7.
[0046] In this invention, a sliding component 9 is installed between the boss 2 and the slide 8, which reduces the sliding friction between the boss 2 and the slide 8 when they slide relative to each other. Under the same elastic force, it helps to increase the contact area between the boss 2 and the slide 8 and improve the power transmission efficiency.
[0047] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, both the slide 8 and the boss 2 are inclined surfaces. The inclined surface design reduces the jerking sensation during rapid deceleration of the slipper clutch, improving driving comfort. It also prevents rear wheel slippage during rapid downshifting at high speeds, improving safety. Furthermore, the inclined surface design allows for a smaller compression and rebound force of the return spring 10, making the clutch lever operation easier for the driver. The sliding assembly 9 includes a sliding groove 12 on the slide 8. A rolling wheel 13 is mounted in the sliding groove 12 via a rotating rod. The outer edge of the rolling wheel 13 abuts against the surface of the slide 8 and the surface of the boss 2. When the boss 2 and the slide 8 move relative to each other, the outer edge of the rolling wheel 13 slides along the surface of the boss 2, reducing the sliding friction between the boss 2 and the slide 8.
[0048] In other embodiments, in order to enable the rolling wheel 13 to slide in a directional manner, the boss 2 is provided with a rolling groove for the rolling wheel 13 to roll. The rolling groove enables the rolling wheel 13 to slide in a directional manner. The outer edge of the rolling wheel 13 abuts against the inner wall of the rolling groove, and the surface of the boss 2 abuts against the surface of the slide 8, increasing the contact area between the boss 2 and the slide 8. The pressure plate assembly 3 is also equipped with a locking pin 14 to prevent the rotating rod from retracting. Specifically, after the rotating rod is installed in the designated position, the locking pin 14 is added. The locking pin 14 is a cotter pin. After it is installed in the designated position, the hole is deformed by riveting to prevent the locking pin 14 from falling off.
[0049] like Figure 1 , Figure 2 and Figure 3As shown, in another embodiment, the limiting component 11 includes a limiting post 15, which is cylindrical and engages with the return spring 10. A connecting plate 16 is connected to the end of the limiting post 15, and the end face of the connecting plate 16 abuts against the end face of the return spring 10. A positioning part 17 is installed on the connecting plate 16 on the side opposite to the limiting post 15, and the positioning part 17 abuts against the end face of the cover plate 7. Specifically, the positioning part 17 is hemispherical, and the hemispherical positioning part 17 abuts against the cover plate 7, reducing the friction between the return spring 10 and the cover plate 7, and at the same time reducing the torsional force on the return spring 10.
[0050] In other embodiments, the limiting component 11 includes a fixing post, which is fixedly connected to the cover plate 7. The fixing post passes through the reset spring 10 and its length is two-thirds to four-fifths of the length of the reset spring 10. The fixing post is used to limit and fix the reset spring 10, thereby reducing the shaking of the reset spring 10.
[0051] In this embodiment, the connecting component 4 includes a connecting bolt 18, and the central sleeve component 1 has a connecting stud 19 that mates with the connecting bolt 18.
[0052] like Figure 2 and Figure 6 As shown in this embodiment, a gear disk 20 is also installed on the central sleeve assembly 1, and the gear disk 20 is used to transmit power.
