ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates to a torsionally-rigid compensating coupling between two shaft ends, particularly for control elements in vehicles, having a ball bearing element positioned on one shaft end and a ball socket element positioned on the other shaft end, and a drive pin extending through a ball bearing of the ball bearing element, the ends of which extend out of the ball bearing element into grooves of the ball socket element.
Dubbel's Fachbuch für den Maschinenbau (Technical Book for Mechanical Engineering), 15
th
Edition, page 409, FIG. 4d, for example, discloses a torsionally-rigid compensating coupling of this type. This coupling is not suited for mounting a ball bearing/ball socket coupling, for coupling shaft ends which are respectively attached to additional elements, for example, to a control element at one end and to a drive motor at the other end. That is, this and other such prior-art torsionally-rigid compensating couplings are not suitable for mounting in a vehicle.
It is an object of the invention, therefore, to provide an easy-to-mount torsionally-rigid compensating coupling, which particularly makes it easy to join the coupling elements.
SUMMARY OF THE INVENTION
According to principles of this invention, a torsionally-rigid compensating coupling between first and second shaft ends has a ball bearing element positioned on the first shaft end and a ball socket element with grooves positioned on the second shaft end, with the ball bearing element including a ball bearing and a drive pin extending through the ball bearing. Pin ends of the drive pin extend out of the ball bearing into the grooves of the ball socket element. The grooves and ball socket of the ball socket element, in a longitudinal direction of the second shaft end, open out into a cylindrical recess that has a guide chamfer. The ball bearing element includes an elastic-force creating member and stops, with the elastic-force creating member driving the drive pin against the stops to fix the drive pin in its working position by elastic force, the drive pin being moveable against the elastic force in a longitudinal direction of the second shaft end.
