Description

Technical Field

[0001] This utility model relates to the field of motorcycle clutch technology, specifically to an outer cover assembly that can reduce the noise of the clutch drive plate. Background Technology

[0002] The clutch in a motorcycle is located between the engine and the transmission and is a critical power transmission component. A friction-plate clutch consists of a housing and a driven element, with the housing connected to the engine's power output.

[0003] When assembling the outer casing assembly, such as Figure 1 As shown, traditional techniques typically place washers on the outer edges of the cover plate and the outer gear to distribute pressure between them and prevent loosening. Additionally, a clearance groove is created on the top surface of the outer gear to facilitate the washer's positioning. However, even with the clearance groove, installing the washer remains difficult. This is because if the outer cover is tilted or vertical, the washer can easily slip off, making installation inconvenient. Furthermore, after prolonged use, the washer can easily shift, causing abnormal noise from the clutch cover.

[0004] Therefore, those skilled in the art are dedicated to developing an outer casing assembly that is easy to install and can reduce noise from the clutch drive plate. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an outer cover assembly that is easy to install and can reduce the noise of the clutch drive plate.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] An outer cover assembly capable of reducing noise from a clutch drive plate includes a gear and a cover plate. A protruding bearing sleeve is provided at the middle position of the gear. A washer is fitted around the outer periphery of the bearing sleeve. The cover plate is sequentially fitted onto the upper surface of the washer. Correspondingly, a limiting groove is formed at the contact point between the cover plate and the washer.

[0008] The beneficial effects of this utility model are as follows: Without changing the existing gear and outer cover structure, this utility model utilizes the bearing sleeve at the center of the gear as the positioning post for the washer. By leveraging the height of the bearing sleeve, the position of the washer is restricted. Even in an upright position, the washer, fitted onto the bearing sleeve, will not slip off, thus fundamentally solving the problem of inconvenient installation. Simultaneously, due to the greater height of the bearing sleeve, even after prolonged use, the washer will absolutely not shift or detach from the bearing sleeve due to vibration. Compared to existing technologies, this fundamentally solves the problem of the washer shifting out of the washer limiting groove due to vibration after prolonged use of the clutch, ultimately resolving the abnormal malfunction of the clutch outer cover. This utility model solves the problem of abnormal noise from the outer cover with minimal technical improvements and the lowest possible cost.

[0009] Specifically, the cover plate has an assembly hole in the middle, through which it is fitted onto the bearing sleeve.

[0010] To enhance the anti-loosening effect and pressure distribution effect of the gasket, the gasket is a butterfly gasket or a gasket with diagonal grooves.

[0011] In order to enable the outer sleeve to be fixedly connected to the gear and to ensure stable transmission, an outer cover is also included. The upper end face of the outer cover is provided with a mounting protrusion, and a buffer sleeve is provided on the outer sleeve of the mounting protrusion. Correspondingly, a buffer sleeve mounting hole is provided on the gear. The position of the outer cover and the gear is restricted by the cooperation between the buffer sleeve mounting hole and the buffer sleeve.

[0012] To allow the outer cover, gear, and cover plate to be assembled sequentially and effectively fixed together, a first mounting hole is provided at the center of the mounting protrusion, and a second mounting hole is provided on the cover plate corresponding to the position of the first mounting hole. The first mounting hole and the second mounting hole are connected by rivets.

[0013] To improve the stability of the transmission between the gear and the outer cover, the cross-section of the mounting protrusion is an equilateral trapezoid, with the short side facing inward and the long side facing outward.

[0014] To further improve the stability of the transmission between the gear and the outer cover, a spring mounting groove is provided on the upper end face of the outer cover, and a buffer spring is provided in the spring mounting groove; spring clearance grooves are provided at corresponding positions on the gear and the cover plate.

[0015] In order to fix and limit the buffer spring, a flange is provided on the side of the spring mounting groove on the cover plate, and the flange is set into the spring mounting groove. Attached Figure Description

[0025] 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.

[0026] 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.

[0027] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] 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.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an outer cover assembly capable of reducing noise from the clutch drive disc includes a gear 1 and a cover plate 2. A protruding bearing sleeve 3 is provided at the center of the gear 1. A washer 4 is fitted around the outer periphery of the bearing sleeve 3, and the cover plate 2 is sequentially fitted onto the upper surface of the washer 4. Correspondingly, a limiting groove 5 is formed at the contact point between the cover plate 2 and the washer 4. Specifically, an assembly hole is provided in the center of the cover plate 2, through which it is fitted onto the bearing sleeve 3.

[0030] This invention utilizes the height of the bearing sleeve on the gear to adjust the position of the washer from the traditional position on the outer periphery of the cover plate and gear to the outer periphery of the bearing sleeve. The height of the bearing sleeve itself limits the position of the washer, preventing slippage during installation regardless of whether the cover is tilted, upright, or horizontal, thus solving the problem of inconvenient washer installation in existing technologies. Simultaneously, a limiting groove adapted to the shape of the washer is provided at the corresponding position on the cover plate to further restrict the washer's position. Combined with the height of the bearing sleeve, the washer's position is further fixed, preventing washer misalignment even after prolonged use, fundamentally solving the problem of abnormal noise caused by washer displacement in the cover.

[0031] In some embodiments, washer 4 is a butterfly washer or a ribbed washer. A butterfly washer can better distribute pressure, while a ribbed washer can more effectively prevent loosening.

[0032] In some embodiments, an outer cover 6 is also included. The upper end face of the outer cover 6 is provided with a mounting protrusion 7, and a buffer sleeve 8 is provided on the mounting protrusion 7. Correspondingly, a buffer sleeve mounting hole is provided on the gear. The position of the outer cover 6 and the gear 1 is restricted by the cooperation between the buffer sleeve mounting hole and the buffer sleeve. The load-bearing capacity at the connection between the gear and the outer cover is enhanced by the mounting protrusion 7, thereby ensuring effective and stable transmission between the gear and the outer cover.

[0033] In some embodiments, a first mounting hole is formed at the center of the mounting protrusion 7, and a second mounting hole is formed at the position corresponding to the first mounting hole on the cover plate 2. The first mounting hole and the second mounting hole are connected by rivets. The gear is mounted on the outer cover, and the cover plate is mounted on the gear. The outer cover, gear, and cover plate can be fixedly connected by rivets to complete the assembly of the outer cover assembly. More preferably, the cross-section of the mounting protrusion 7 is an equilateral trapezoid, with the short side facing inward and the long side facing outward. Making the mounting protrusion 7 the core component for the gear to transmit power to the outer cover, the trapezoidal design with a wider outer side and a narrower inner side prevents deformation and further improves the stability of the gear's transmission to the outer cover.

[0034] In some embodiments, the upper end face of the outer cover 6 is also provided with a spring mounting groove, and a buffer spring 10 is provided in the spring mounting groove; spring clearance grooves are provided at corresponding positions on the gear 1 and the cover plate 2. More preferably, the edge of the spring mounting groove on the cover plate 2 is provided with a flange 9, which is fastened into the spring mounting groove. This structure can avoid the deformation effect of the cover plate on the spring and can also effectively prevent the spring displacement, thereby increasing the buffering effect of the buffer spring.

[0035] During assembly, first, the gear and the outer cover are positioned according to the location of the mounting protrusion 7. Then, the buffer spring 10 and the buffer sleeve 8 are installed in sequence. Next, the washer is put on the outer circumference of the bearing sleeve of the gear. Finally, the cover plate is put on and the rivets are passed through the first mounting hole and the second mounting hole. The installation is convenient, the structure is stable, the position of the washer is fixed and will not be displaced, which can avoid the problem of noise caused by the displacement or offset of the washer.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
