Example Embodiment

[0031] Example 1:

[0032] Such as Figure 1-5 As shown, a DST structure clutch cover tongue 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 zone 2 and a deformation zone 3; the deformation zone 3 is provided at one end of the bending zone 2, and the other end of the bending zone 2 is assembled according to the matched clutch cover assembly 5 The structure is bent; a bending groove 4 is provided on the deformation zone 3.

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

[0034] The width a of the bending groove 4 is ≥ the diameter of the s...

Example Embodiment

[0041] Example 2:

[0042] The difference between this embodiment and the first embodiment is that the edge of the bending zone 2 is tapered. The taper of the edge of the bending zone 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 the first embodiment.

Example Embodiment

[0044] Example 3:

[0045] The difference between this embodiment and the second embodiment is that the junction of the bending zone 2 and the deformation zone 3 is a rounded transition. Such a design can enhance the strength of the deformation zone 3, so that the deformation zone 3 is not easily damaged during bending.

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

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. 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 misalignm...
