Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an improvement of a wire for temporarily assembling a clutch cover assembly, which has been conventionally used to facilitate assembly of the clutch cover.

(Prior Art and its Problems) Conventionally, when temporarily assembling a clutch cover assembly having a diaphragm spring, as shown in FIG. The height of the lever of the diaphragm spring 12 that presses the pressure plate 16 is made uniform over the entire circumference.

At the end of the temporary assembly wire 14, a fourth
As shown in the figure, a grip part 18 is formed, and when installing the clutch cover assembly on the flywheel of the engine, pull this grip part 18 to remove the temporary assembly wire 14, and then attach the clutch cover assembly. Must be fixed to the flywheel.

However, in the above conventional example, there is a risk that the clutch cover assembly may be attached to the flywheel with the temporary assembly wires 14 still sandwiched between them, and if you forget to remove the temporary assembly wires 14, you may have to re-attach the clutch cover assembly to the flywheel. There is the problem of having to remove the clutch cover assembly.

(Purpose of the invention) The object of the invention is to provide a wire for temporary assembly of a clutch cover assembly that does not require forgetting to remove the wire for temporary assembly.

(Structure of the invention) (1) Technical means The present invention is designed to connect the end of the temporary assembly wire that is sandwiched between the inner circumferential edge of the clutch cover and the diaphragm spring to the inner circumference of the diaphragm spring when temporarily assembling the clutch cover assembly. This is a wire for temporary assembly of a clutch cover assembly, which is characterized by being stretched to the inside of the clutch cover assembly.

(2) Effect Since the end of the temporary assembly wire gets caught on the stepped part when removing the dummy shaft, there is no risk of forgetting to remove the temporary assembly wire.

(Example) A clutch cover assembly to which the present invention is applied was
This will be explained with reference to FIGS. In FIGS. 1 and 2, parts with the same reference numerals as those in FIG. 3 indicate the same or equivalent parts.

In FIG. 1, which shows the clutch cover assembly being positioned on the flywheel 20, a dummy shaft 24 is fitted into the pilot bearing 22 of the flywheel 20 in place of the input shaft of the transmission. A clutch disk 26 is disposed between the flywheel 20 and the pressure plate 16, and a spline hub 27a of the clutch disk 26 is spline-fitted to the large diameter portion 25a of the dummy shaft 24 for positioning.

A plate assembly wire 30, which is the gist of the present invention, is sandwiched between the tongue portion 11a of the clutch cover 10 and the diaphragm spring 12. As shown in FIG. 2, the annular portion 3 of the temporary assembly wire 30
1a forms a substantially annular shape along the inner circumferential edge of the clutch cover 10 and extends over substantially the entire circumference of the clutch cover 10. A grip portion 31b is formed at one end of the annular portion 31a, and an extension portion 31c is formed at the other end of the annular portion 31a.

The extension portion 31c extends toward the center of the clutch cover assembly, and the end portion of the extension portion 31c reaches a portion corresponding to the stepped portion 25b of the dummy shaft 24. The large diameter portion 25a of the dummy shaft 24 is the first
As shown in the figure, it is formed closer to the flywheel 20 than the extension portion 31c.

The above temporary assembly wire 30 is, for example, SWB
Continuously formed of spring steel such as.

Next, the effect will be explained. After positioning the clutch disk 26 and the clutch cover assembly on the flywheel 20 using the dummy shaft 24, the clutch cover 10 is fixed to the flywheel 20 with bolts, and the transmission is attached from behind the clutch cover assembly.

Before installing this transmission, dummy shaft 2
4, but if you forget to remove the temporary assembly wire 30, the extension part 31c of the temporary assembly wire 30 will get caught on the stepped part 25b of the dummy shaft 24, and the dummy shaft 24 cannot be removed, so be sure to use wire 30 for temporary assembly.
You will realize that you forgot to remove it. Therefore, there is no possibility of forgetting to remove the temporary assembly wire 30.

When the temporary assembly wire 30 is removed, the pressure plate 16 is pressed by the diaphragm spring 12, and the clutch disk 26 is pressed against the flywheel 20, so that the clutch disk 26 is fixed. Therefore, even if the dummy shaft 24 is removed in this state, the clutch disc 26
The positioning will not shift.

(Effect of the invention) As explained above, the temporary assembly wire of the clutch cover assembly according to the invention is the temporary assembly wire that is sandwiched between the inner peripheral edge of the clutch cover and the diaphragm spring when the clutch cover assembly is temporarily assembled. When assembling the clutch cover assembly to the engine flywheel, extend one end to the part that corresponds to the stepped part of the dummy shaft that is temporarily installed in place of the transmission side input shaft for positioning the clutch disc. Therefore, the following effects can be achieved.

When installing the transmission after positioning the clutch cover assembly on the flywheel 20,
It is necessary to remove the dummy shaft 24 before installing the transmission, but in case the temporary assembly wire 30
If you forget to remove the extension part 31c of the temporary assembly wire 30, the extension part 31c of the dummy shaft 24
5b, the dummy shaft 24 cannot be removed, and the dummy shaft 24 cannot be removed unless the temporary assembly wire 30 is removed. It can make you notice.

Therefore, when attaching the clutch cover assembly to the flywheel 20, it is possible to prevent the inefficient work of forgetting to remove the conventional temporary assembly wire 30 and performing the disassembly work again. The efficiency of the attachment work to the wheel 20 can be improved.
