Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts and other derivative industries, and particularly relates to an improved dry friction type double-disc clutch pressure cover mechanism. Background Art

[0002] With the use of the double-disc clutch assembly, since two driven disc assemblies simultaneously perform frictional work, the generated dust is twice that of a common clutch, and the generated heat is also twice that of a common clutch. The dust cannot be removed in time and the heat cannot be transferred out in time, resulting in the double-disc clutch being more prone to ablation and difficulties or failures in gear shifting. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an improved dry friction type double-disc clutch pressure cover mechanism, an improved cushion block, and a strip-shaped notch, which replace the traditional closed cover hoop. Four identical improved cushion blocks are equally spaced and evenly distributed at the bottom of the clutch cover plate, which not only ensures the conformability during the installation process of the clutch cover plate, but also leaves a gap space between the improved cushion blocks, replacing the structure of the traditional gasket ring being entirely annularly sealed, thus improving the drawbacks of the closed structure of the traditional double-disc clutch. Thereby solving the problems that due to the closed original structure of the double-disc clutch, the dust removal and heat dissipation of the double-disc clutch in the working environment are poor, resulting in too high a working temperature of the friction plate, and the occurrence of clutch ablation or difficulties or failures in gear shifting.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] An improved dry friction type double-disc clutch pressure cover mechanism of the utility model includes a clutch cover plate, a clutch pressure plate assembly, and a limiting mechanism. Four identical improved cushion blocks are arranged on the inner side of the bottom of the clutch cover plate. A plurality of strip-shaped notches and bottom slots for improved rivets are drilled on the improved cushion blocks, and a plurality of top slots for improved rivets are provided on the clutch cover plate body directly above the bottom slots for improved rivets in the vertical direction.

[0006] The tops of the four identical improved cushion blocks are fixed to the bottom of the clutch cover plate by a plurality of welding rivets.

[0007] The four identical improved cushion blocks are equally spaced and evenly distributed at the bottom of the clutch cover plate.

[0008] The spacing between the four identical improved cushion blocks constitutes the installation area of the limiting mechanism.

[0009] The top slots for improved rivets and the bottom slots for improved rivets are connected and fixed by threaded rivets.

[0010] The clutch cover plate is a structure integrally shaped and cast.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model: the improved cushion block and the strip-shaped notch replace the traditional closed cover hoop. The four identical improved cushion blocks are equally spaced and evenly distributed at the bottom of the clutch cover plate, which not only ensures the conformability during the installation process of the clutch cover plate, but also leaves a gap space between the improved cushion blocks, replacing the structure where the traditional gasket ring is entirely annularly sealed, improving the drawbacks of the closed structure of the traditional two-plate clutch. Thus, it solves the problems that in a two-plate clutch, due to the closed original structure of the clutch, the dust removal and heat dissipation are poor in the working environment, resulting in too high a working temperature of the friction plate, and causing clutch ablation, difficult gear shifting or failures. It is a specially designed and improved dry friction type two-plate clutch pressure cover mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] Embodiment 1

[0022] As Figure 1-2 shown, the present utility model provides an improved dry friction type double-disc clutch pressure cover mechanism, which includes a clutch cover plate 1, a clutch pressure plate assembly 2 and a limiting mechanism 3. Four identical improved pads 4 are arranged on the inner side of the bottom of the clutch cover plate 1. A plurality of strip-shaped notches 5 and improved rivet bottom holes 6 are drilled in the improved pads 4. And directly above the vertical of the improved rivet bottom hole 6 and on the body of the clutch cover plate 1, a plurality of improved rivet top holes 7 are provided.

[0023] The tops of the four identical improved pads 4 are fixed to the bottom of the clutch cover plate 1 by a plurality of welding rivets 8. The improved pads 4 change the disadvantages that the traditional gasket ring 401 and the closed cover hoop 501 in the traditional design cannot discharge dust and heat.

[0024] The four identical improved pads 4 are equidistant and evenly distributed at the bottom of the clutch cover plate 1 to ensure the flatness during the installation of the clutch cover plate 1.

[0025] The spacing between the four identical improved pads 4 constitutes the installation area of the limiting mechanism 3. The limiting mechanism 3 is an essential structure provided on the circumferential side surface of the double-disc clutch.

[0026] The improved rivet top hole 7 and the improved rivet bottom hole 6 are connected and fixed by a threaded rivet 9, and can be flexibly operated during the disassembly and installation process.

[0027] The clutch cover plate 1 is a structure integrally formed by plastic casting, with strong toughness, wear resistance and fracture prevention.

[0028] Working principle: The improved pads 4 and the strip-shaped notches 5 replace the traditional closed cover hoop 501. The four identical improved pads 4 are equidistant and evenly distributed at the bottom of the clutch cover plate 1, which not only ensures the flatness during the installation of the clutch cover plate 1, but also leaves a gap space between the improved pads 4, replacing the structure where the traditional gasket ring 401 is entirely annularly sealed, improving the disadvantages of the closed structure of the traditional double-disc clutch.

[0029] Thus, it solves the problems that due to the closed original structure of the double-disc clutch, the dust removal and heat dissipation of the double-disc clutch in the working environment are poor, resulting in too high working temperature of the friction plate, and the clutch ablation or difficult gear shifting or failure occurs.

[0030] As shown in the attached Figure 3-4 drawing,

[0031] Figure 3 is one of the schematic diagrams of the prior art for comparison with the present utility model;

[0032] Figure 4 is the second schematic diagram of the prior art for comparison with the present utility model;

[0033] In the attached drawings of its specification Figure 3-4 As shown, the original clutch cover plate 101 is significantly different from the clutch cover plate 1; both the original clutch pressure plate assembly 201 and the clutch pressure plate assembly 2 meet the design requirements applicable to the dry friction type double-plate clutch assembly; the original limiting mechanism 301 and the limiting mechanism 3 have different notch shapes, so the later installation and disassembly methods are also different; the traditional gasket ring 401 is a ring-shaped sealing structure. After the combined action of the bottom slot hole 601 of the original rivet, the top slot hole 701 of the original rivet, and the original threaded rivet 901, the structure is made to fit closely. Also, due to the action of the closing cover hoop 501 and the original welded rivet 801, the structure of the traditional double-plate clutch is closed, resulting in poor dust removal and heat dissipation in the working environment of the double-plate clutch, which causes the working temperature of the friction plate to be too high, leading to clutch ablation or difficult gear shifting or malfunctions.

[0034] In the present utility model, the improved cushion block 4 and the strip-shaped notch 5 replace the traditional closing cover hoop 501. The four identical improved cushion blocks 4 are equally spaced and evenly distributed at the bottom of the clutch cover plate 1, which not only ensures the fit during the installation process of the clutch cover plate 1, but also there are gap spaces between the improved cushion blocks 4, replacing the entire ring-shaped sealing structure of the traditional gasket ring 401, thus improving the drawback of the closed structure of the traditional double-plate clutch.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
