DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase of PCT/DE92/00974 filed Nov. 17, 1992 and based, in turn, upon German national application P 41 41 520.5 filed Dec. 15, 1991 under the International Convention.
FIELD OF THE INVENTION
The invention relates to a coupling for balancing the radial movements and axial displacement between a first coupling half and a second coupling half with an unsupported intermediate member which is connected by means of two connecting rods with the first coupling half on the one side and by a further two connecting rods with the second coupling half on the other side whereby the intermediate member consists of two ark-shaped detachably interconnected intermediate member halves.
A coupling of the type described above is known for instance from DE-OS 30 49 054. As described therein, it serves particularly for the transmission of the motor output of an electrically driven rail vehicle from a first flange of a hollow shaft to a second flange of a drive axle enclosed by the hollow shaft and radially movable relative thereto. For this purpose a four-member linkage is formed by the first flange, the first pair of connecting rods and the intermediate member as the driving first coupling half, and a second four-member linkage is formed by the intermediate member, the connecting rods and the second flange as the driven second coupling half. The intermediate member consists of two arc-shaped halves divided in transverse direction with respect to its axis, which are releasably connected by two screws arranged approximately tangentially. This makes possible to fit the intermediate member and the connecting rods later or to dismantle them. However this is quite cumbersome. Besides the known coupling has a relatively expensive construction, particularly in with respect to the intermediate member.
OBJECT OF THE INVENTION
It is therefore the object of the invention to provide a coupling of the aforedescribed type, which can be fitted and dismantled more easily, and has a considerably simpler configuration of the intermediate element.
SUMMARY OF THE INVENTION
This object is achieved, in accordance with the invention, in a coupling of the type described in which the intermediate member halves overlap each other peripherally with their end sections and are held together in each of the two overlap regions by two aligned axial bores receiving bolts securing the connecting rods. Each of the intermediate member halves is cut out from sheet metal and at least the two end sections of each intermediate member half are located in a common plane.
Advantageously, the intermediate member halves are cut out from sheet steel or sheet titanium. The intermediate member halves can have at least one additional overlapping area at which they are detachably interconnected. The connecting rods can be forked in the areas adjoining the intermediate member and the intermediate member can be received between arms of the forks.
According to the invention, the connecting rods can be shaped without forks and a pair of the intermediate member halves can be arranged in front of the axially oriented outer sides of the connecting rods.
Inner areas of the intermediate member halves of at least one of two intermediate members can be bent toward each other out of the plane of the respective end sections. The inner areas of the intermediate member halves can be so formed that they can touch each other and be detachably interconnected where they are in common contact.
According to the invention the bolts attaching the connecting rods to the intermediate member serve at the same time for the mutual connection of the intermediate member halves. Compared to the state of the art, the two special screws, as well as all steps and arrangement for their fitting and handling, are eliminated. But most important is the configuration of the intermediate member halves, which are designed so that both end sections of an intermediate member half are in parallel planes but closely adjoin one another.
