MAGNET ASSEMBLY, AND MAGNETIC PLASTIC PART FOR SUCH A MAGNET ASSEMBLY
First Claim
1. A magnet assembly comprising a ring-shaped plastic part having magnetic properties, and a metal support sleeve which is situated coaxially with respect to the plastic part and permanently connected to the plastic part, and which has at least one flange element on the end-face side, wherein the plastic part with one of its end-face sides rests directly against the at least one flange element of the support sleeve, and by means of at least two formations on the plastic part, which protrude away from said end-face side of the plastic part, is connected in a form-fit manner to the one flange element or in a form-fit manner to the multiple flange elements of the support sleeve, so that the plastic part and the support sleeve are fixedly connected to one another in the coaxial direction via the form-fit connection.

Abstract
In a magnet assembly (1), as is used for measuring rotation angles and torques for example, a magnetic plastic part (2) is connected to a metal support sleeve (3) in such a way that the plastic part bears directly against flange elements (5, 6) of the support sleeve (3), and that formations (10, 11) on the plastic part establish a form-fit connection between the plastic part and the support sleeve which connects these in the direction of the common center longitudinal axis of plastic part and support sleeve. The form-fit connection itself may be nonreleasable and thus permanent, or additional blocking means may be provided which prevent release of the form-fit connection.
