Problems solved by technology

Therefore, the balls received in the raceway cannot move relative to the outer ring, so that the balls cannot roll in the raceway, but the relative movement between the outer ring and the inner ring can only be formed by the movement / sliding of the balls in the raceway of the inner ring. Movements in the raceways cause high frictional moments in the joints, which lead to heating and rapid wear during operation

Embodiment Construction

[0021] The figure shows a sliding joint 1, which has a substantially cylindrical outer ring 2, an inner ring 3 received in a cavity defined by the outer ring 2 and a joint between the outer ring 2 and the inner ring 3. Between the guided cage 4. The cage 4 here has nine windows 5 which are distributed at regular intervals in the circumferential direction of the cage 4 and each of which accommodates a ball 6 .

[0022] Formed in the outer ring 2 are nine raceways 7 corresponding to the windows 5 of the cage 4 , said raceways being substantially parallel to the axis A of the sliding joint 1 2 extend. The raceway 7 here is delimited on the one side by a step 8 of the outer ring 2 and on the other side by a limiting stop 9 formed by a bellows support 10 fastened to the outer ring 2 .

[0023] Nine axes A parallel to the inner ring 3 are also formed on the inner ring 3 3 Extended raceway 11, the axis of which is the axis of the joint when the inner ring 3 is centered in the oute...

Abstract

The invention concerns a sliding articulation ( 1 ) comprising an outer hub ( 2 ) wherein is housed an inner hub ( 3 ). The outer hub ( 2 ) and the inner hub ( 3 ) comprise corresponding respective raceways ( 7, 11 ) wherein are housed balls ( 6 ) which are guided by a cage ( 4 ) arranged between the outer hub ( 2 ) and the inner hub ( 3 ). The invention is characterized in that the inner hub ( 3 ) can slide freely relative to the outer hub ( 2 ) in the axial direction, between a first stop ( 8 ) and a second stop ( 9, 21 ), over a distance ( 14 ), when the balls ( 6 ) roll in the raceways ( 7, 11 ) and it can slide over a second distance ( 13 ) when the balls ( 6 ) slide in the raceways ( 7, 11 ).

Description

technical field [0001] The invention relates to a sliding joint / universal joint (Verschiebegelenk), which can be used, for example, in cardan shafts of automobiles or the like, which has an axis that surrounds a cavity and has an axis parallel to the sliding joint on its inner surface an outer race of an extended raceway, an inner race received in said cavity, said inner race having on its outer surface a raceway extending parallel to the axis of the slip joint, this raceway and the outer raceway on the outer raceway The raceways are opposite and in pairs each accommodates a ball together, and also have a cage arranged between the outer ring and the inner ring to guide the balls in the axial direction. Background technique [0002] In cardan shafts used, for example, in automobiles as longitudinal shafts or half shafts for transmitting the drive torque from the gearbox to the drive wheels, it is common to allow the length of the shaft to be changed in order to install or to ...
