Embodiment Construction

[0080] Figure 1 to Figure 5 will be collectively described below. Figure 1 to Figure 5 The sealing element 2 of the invention is shown in a first embodiment arranged in the form of a membrane. The sealing element 2 comprises: an inner ring 3 for providing a sealed connection with respect to the inner joint part or a component connected to the inner joint part; The outer ring 4 of the sealing connection of the part parts; and the membrane part 5 extending between the inner ring 3 and the outer ring 4 and connecting the inner ring 3 and the outer ring 4 . The outer ring 4 is provided in the form of an annular rim capable of sealingly engaging a corresponding annular groove (not shown) in a form-fitting manner. The outer ring 4 seamlessly adjoins the membrane portion 5 .

[0081] It can be seen that the membrane portion 5 (which may also be referred to as an intermediate portion) comprises a substantially conical shape rising with reference to the axis of rotation A from the...

Abstract

The invention relates to a sealing element (2) for sealing a joint chamber (31) of a constant velocity joint (17). The sealing element (2) comprises an inner ring (3) for providing a sealed connection against the inner joint part (19) of the constant velocity joint (17), ) The outer ring (4) of the outer universal joint part (18) of the sealing connection, the membrane part (5) extending between the inner ring (3) and the outer ring (4), wherein the inner ring (3) and the outer The membrane portion ( 5 ) between the loops ( 4 ) is unfolded and substantially conical in shape. The invention also relates to a joint assembly (16) with a constant velocity joint (17) and such a sealing element (2).

Description

technical field [0001] The present invention relates to a sealing element for a constant velocity joint, and a constant velocity joint assembly comprising such a constant velocity joint and such a sealing element for sealing a joint chamber. Background technique [0002] A joint assembly with a sealing device is known from DE 10 2006 006 441 A1, the joint assembly comprising a constant velocity joint and a sealing membrane. A constant velocity joint consists of: an outer joint section; an inner joint section, with torque-transmitting balls guided in the fairways of the outer joint section and the inner joint; and a ball cage, in which the ball is retained . The sealing membrane includes an inner ring that is rigidly connected to the sleeve at the inner gimbal portion, and an outer ring that is securely connected to the annular cap at the outer gimbal portion. The sealing membrane includes annular folds between the inner and outer rings. [0003] Sealing elements in consta...
