Problems solved by technology

[0002] The clutch is a key component of the automobile transmission system. The traditional automobile clutch cover assembly is often assembled one by one by rivets. The clutch cover assembly assembled in this way has the potential for loosening and failure.
At present, a small number of DST structure clutch cover assembly new assembly technology uses tongues for press assembly. The traditional tongues are integral, without specific deformation areas, and there are no measures to reduce bending stress. One-time forming due to excessive bending angle Large, it is easy to cause the tongue to break; at the same time, due to the uncertainty of the deformation area, there is a risk of product hole position deformation and misalignment during the bending process of the tongue, which will affect the accuracy of the final product; and if the tongue is molded by secondary molding Bending will affect production efficiency and increase unnecessary production costs

Embodiment 1

[0032] Such as Figure 1-5 As shown, a clutch cover tongue of a DST structure that facilitates bending and forming includes a tongue body 1; the workpiece to be assembled with the tongue body 1 includes a clutch cover assembly 5, a support ring 6 and a diaphragm spring 7 ; The tongue body 1 includes a bending area 2 and a deformation area 3; The structure is bent; the deformation zone 3 is provided with a bending groove 4 .

[0033] The bending groove 4 is arranged on the side of the deformation zone 3 , and is a through groove at both ends, passing through two opposite sides of the deformation zone 3 . The deformation zone 3 can be bent toward the opening direction of the bending groove 4 by taking the bending groove 4 as an apex.

[0034] The width a of the bending groove 4 ≥ the diameter of the support ring 6 . This size can ensure that the deformation zone 3 can reach a certain angle after being bent, and ensure that the tongue body 1 is not broken, and at the same time...

Embodiment 2

[0042] The difference between this embodiment and embodiment 1 is that the edge of the bending area 2 is tapered. The taper of the edge of the bending area 2 can reduce part of the stress and protect the tongue body 1 from being damaged.

[0043] The usage method of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0045] The difference between this embodiment and embodiment 2 is that: the connection between the bending area 2 and the deformation area 3 is a round corner transition. Such a design can enhance the strength of the deformation zone 3 and make the deformation zone 3 less likely to be damaged during bending.

[0046] The usage method of this embodiment is the same as that of Embodiment 1.

Abstract

The invention discloses a DST structure clutch cover tongue piece favorable for bending and forming and a using method of the DST structure clutch cover tongue piece. The DST structure clutch cover tongue piece comprises a tongue piece body; a workpiece to be matched with the tongue piece body to perform assembling is provided with a clutch cover assembly, a bearing ring and a diaphragm spring; the tongue piece body comprises a bending area and a deforming area; the deforming area is arranged at one end of the bending area; the other end of the bending area performs bending according to the structure of the matched and assembled clutch cover assembly; and a bending groove is formed in the deforming area. The device is simple in structure and ingenious in design, the tongue piece self is protected and thus is not prone to breakage or damage while it is guaranteed that the bearing ring and the diaphragm spring are riveted tightly, the product precision is improved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of auto parts manufacturing, and in particular relates to a clutch cover tongue sheet with DST structure which is beneficial to bending and forming and a using method thereof. Background technique [0002] The clutch is a key component of the automobile transmission system. The traditional automobile clutch cover assembly is often assembled one by one by rivets. The clutch cover assembly assembled in this way has the potential for failure. At present, a small number of DST structure clutch cover assembly new assembly technology uses tongues for press assembly.
