Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a novel clutch driving hub. Background Art

[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. During the driving process of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and gearbox to cut off or transfer the power input from the engine to the transmission. The clutch is a wearing part. When engaged, the friction plates of the clutch rub against each other. During the friction process, the friction plates squeeze the active hub, causing damage to the active hub. In serious cases, the friction plates are embedded in the active hub, causing damage to the active hub and a short service life.

[0003] Therefore, it is necessary to provide a new clutch driving hub to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a novel clutch driving hub.

[0005] The utility model provides a new clutch active hub, characterized in that it comprises a plurality of metal sheets for wrapping protective shell sheets and an active hub shell body, the inner side and side edges of the protective shell sheets of the active hub shell body are wrapped by the metal sheets, the metal sheets are provided with more than one trapezoidal grooves, the protective shell sheets are provided with more than one trapezoidal blocks, the trapezoidal grooves correspond to the trapezoidal blocks one by one, and the metal sheets and the active hub shell body are integrally formed by casting.

[0006] Preferably, the metal sheet is U-shaped.

[0007] Preferably, the metal sheet is made of stainless steel.

[0008] Preferably, the material of the active hub housing is aluminum.

[0009] Preferably, the thickness of the metal sheet is 1 mm to 2 mm.

[0010] Compared with the related art, the new clutch driving hub provided by the utility model has the following beneficial effects:

[0011] The structure wraps the protective shell of the active hub with a metal sheet. The metal sheet directly contacts the friction plate instead of the protective shell, thereby improving the hardness of the protective shell and extending the service life of the active hub. The metal sheet has a trapezoidal groove, and the active hub is prepared by casting molten aluminum. The metal sheet and the protective shell can be firmly connected, which has good practicality.

[0016] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0017] Please refer to Figure 1-Figure 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the new clutch driving hub provided by the utility model; Figure 2 An exploded schematic diagram of a novel clutch driving hub provided by the utility model; Figure 3 This is a schematic diagram of the cross-sectional structure of the protective shell 11 provided by the present invention.

[0018] In the specific implementation process, Figure 1-Figure 3 As shown, a novel clutch driving hub comprises a plurality of metal sheets 12 for wrapping a protective shell sheet 11 and a driving hub shell 1, wherein the inner side and the side edge of the protective shell sheet 11 of the driving hub shell 1 are wrapped by the metal sheet 12, and the metal sheet 12 is provided with one or more trapezoidal grooves 121, and the protective shell sheet 11 is provided with one or more trapezoidal blocks 111, and the trapezoidal grooves 121 correspond to the trapezoidal blocks 111 one by one, and the metal sheet 12 and the driving hub shell 1 are integrally formed by casting. Specifically, there are 12 protective shell pieces 11 in the figure, and correspondingly, there are 12 metal pieces 12, and there are three trapezoidal grooves 121 on the metal piece 12, that is, the number of trapezoidal blocks 111 is three, and the trapezoidal grooves 121 shrink from the metal piece 12 toward the protective shell piece 11. After the metal piece 12 and the active hub shell 1 are cast and formed, corresponding trapezoidal blocks 111 are formed on the protective shell piece 11, which has good connection firmness; the metal piece 12 is U-shaped, and the metal piece 12 wraps the inner side and side of the protective shell piece 11, replacing the protective shell piece 11 to contact with the friction plate, effectively improving the structural strength, and having good practicality.
