Abstract
A protective device for a driving assembly with a double universal joint has a protective cone ( ) made of plastic. At a first axial end, the protective cone ( ) is secured to a bearing assembly ( ). At its second axial end ( ), the protective cone ( ) carries a guiding ring ( ). Folds ( ) are arranged between the axial ends. A hollow-spherical-zone-like inner bearing face ( ) of the guiding ring ( ) is arranged on a spherical outer bearing face ( ) of a bearing race ( ). A sliding ring ( ) in the bearing race ( ) is supported in a bearing groove ( ) of the double yoke ( ) of the double universal joint ( ). The guiding ring ( ) is pre-tensioned by the folds ( ) of the protective cone ( ) and thus held in contact with the outer bearing face ( ). The guiding ring ( ) can be removed from the bearing assembly, thus making components of the double universal joint accessible for maintenance purposes, such as lubrication.
