Abstract
A protective device for a drive assembly with a double universal joint (1) has a protective cone (10) with folds (15). At the cone's first axial end (11), it is secured to a bearing assembly (12). At its second axial end, the cone (10) includes a fixing portion (14) which is connected to a guiding ring (18). The guiding ring (18), via its inner end (21) projects into the part of the protective cone (10) which is provided with the folds. The guiding ring (18) itself is supported on a bearing ring (23). The bearing ring (23), in turn, is supported on an inner double yoke (5). An axial relative movement is permitted between the guiding ring (18) and the bearing ring (23). The guiding ring (18) ensures that the protective cone (10), with the folds (15), is well supported under articulation conditions. Furthermore, the protective cone (10) with its folds (15) has a relatively long length without losing any of its stability.
