DE102005029526A1 - Connection between disc and shaft, in particular with a drive of motor vehicle is formed as crimp connection in such manner that mounting of disc on shaft is made possible in installed condition of shaft as well - Google Patents

Abstract

The connection is formed as a crimp connection in such a manner that the mounting of the disc (2) on the shaft (1) is made possible in the installed condition of the shaft as well. The shaft, which can be connected with the disc, exhibits a step (5), on which the disc is stuck.

Description

The The present invention relates to a connection between a disk and a shaft, in particular in a transmission of a motor vehicle, according to the preamble of claim 1

to Connection of a disc with a shaft, such as the detent disc with a selector shaft in an automatic transmission, often wobble riveting or compression connections used. In these cases, the detent disc with the selector shaft Assembled in a separate completion.

These Procedure is disadvantageously not suitable if the Case occurs that the pre-assembled completion of disc and wave for space reasons not in the case or the transmission housing can be inserted.

Of the present invention is based on the object, a compound specify between a disc and a shaft, which in the Installation position of the shaft can be mounted.

These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.

Therefore becomes a connection between a disc and a shaft, in particular in a transmission of a motor vehicle, proposed which as Crimping performed is such that the mounting of the disc on the shaft is also built-in State of the shaft allows becomes.

According to the invention the shaft to be connected to the disc has a groove which is such arranged is that a piece of pipe, which is placed on or above the disk on the shaft, with the upper edge of the groove closes. The disc is on one put appropriate shoulder on the shaft after the shaft is positioned in the housing has been.

According to the invention pipe section with a suitable tool, such as a two- or multi-part die tool, squeezed into the groove of the shaft. In this way, the disc is on the one hand by the pipe section and on the other hand axially secured the heel of the shaft.

in the Within the framework of an advantageous development of the invention, it is provided that the groove on the side facing away from the disk to be fastened with a slope is provided. In this way, the connection can axial tolerances compensate, provided the pipe section also with a suitable, cooperating with the slope of the groove slope is provided. about the slope is during the crimping also applied a force in the axial direction.

Of the Heel on the shaft to which the disc is attached can designed as a round bore be provided that no rotation of the disc on the shaft required is.

In the case, that a rotation is required, which, for example is the case with a detent disk, this can according to the invention via a Twofold in the disc or over Any other, known in the art devices for anti-rotation be achieved.

The The invention will be explained in more detail below by way of example with reference to the attached figures. Show it:

1 a schematic perspective view of the inventive compound between a disc and a shaft in the first phase of assembly;

2 a schematic sectional view of the inventive compound between a disc and a shaft in the first phase of assembly;

3 a schematic perspective view of the inventive compound between a disc and a shaft in the second phase of assembly;

4 a schematic sectional view of the inventive compound between a disc and a shaft in the second phase of assembly;

5 a schematic perspective view of the connection according to the invention between a disc and a shaft after installation and

6 a schematic sectional view of the connection according to the invention between a disc and a shaft after installation.

In the 1 to 6 is the shaft serving as selector shaft with 1 and with the shaft 1 designated to be connected detent disc with 2. The one with the disc 2 to be connected wave 1 has one in the 2 . 4 and 6 illustrated groove 3 auf, which is arranged according to the invention such that a pipe section 4 , that after or above the disc 2 on the wave 1 is plugged, with the upper edge of the groove 3 concludes.

The wave 1 also has a in the 2 . 4 and 6 presented paragraph 5 on top of that the disc 2 gets stuck after the wave 1 has been positioned in the housing.

In the 1 and 2 are the wave 1 and those with the wave 1 to be connected disc 2 shown in the first phase of assembly, in which the disc 2 on the heel 5 the wave 1 is plugged and the pipe section 4 after or above the disc 2 on the wave 1 is plugged.

According to the invention, the pipe section during assembly 4 with a suitable tool, for example with a two- or multi-part die tool 6 , in the groove 3 the wave 1 squeezed, leaving the disc 2 on the wave 1 between the paragraph 5 and the pipe section 4 is axially secured. This is the subject of 3 and 4 ,

In the 5 and 6 becomes the connection between the shaft 1 and the detent disk 2 shown in the assembled state.

In the in the 1 to 6 embodiment shown, the groove 3 on the disk to be fastened 2 opposite side into the 2 . 4 and 6 illustrated slope 7 on; In addition, the pipe section 4 with a corresponding slope 8th provided so that thereby axial tolerances can be compensated.

By the concept of the invention is provided a connection between a disc and a shaft, which allows mounting of the disc, even if the Shaft already in the installation position. Such a connection is especially for the connection of a selector shaft suitable with a detent disc in an automatic transmission.

Of course, too each constructive embodiment of the inventive compound between a Disc and a shaft, in particular the shape of the groove, the pipe section and the sloping, as far as technically reasonable, under the scope of protection of the present Claims, even if these trainings are not explicitly in the figures or are shown in the description.
