Abstract:
A constant velocity plunging joint comprising:an outer joint part (11, 31) having a cylindrical hollow chamber (12, 32) with an aperture (13, 33) at a first end and being closed by a base (14, 34) at an opposite end and further including uniformly circumferentially distributed, longitudinally extending tracks (17, 37);an inner joint part (21, 41) positioned centrally in said cylindrical hollow chamber (12, 32) of said outer joint part (11, 31) so as to be angularly movable and longitudinally displaceable;an assembly comprising said inner joint part (21, 41) and a plurality of torque transmitting elements (23, 43);said torque transmitting elements (23, 43) which, in the direction of rotation, are form-fittingly connected to said inner joint part (21, 41) and which, in the direction of rotation, engage said tracks (17, 37) of said outer joint part (11, 31) form-fittingly and so as to roll therein in a longitudinal direction;said aperture (13, 33) of said outer joint part (11, 31), having an end face (18, 38) including a plurality of caulkings (19, 39) which form raised portions (20, 40), said caulkings (19, 39) reducing the free inner cross-section of said cylindrical hollow chamber (12, 32);said assembly received through said aperture (13, 33) into said hollow chamber (12, 32); andsaid raised portions (20, 40) being permanently unhardened and adapted to deform elastically and plastically as said assembly is first introduced into said hollow chamber (12, 32) through said aperture (13, 33), said raised portions (20, 40) exerting an axial holding force on said assembly (23, 43), to prevent any self-acting dismantling.
