Abstract

The invention relates to a protective device which is supported on the two universal joints (2, 2') by connecting caps (8) and sliding ring. Furthermore, each connecting cap (8) is formed to allow a protective cone (12) to be connected thereto. Protective devices of said type provide protection against contact and are stationary, while the driveshaft (1) rotates. Each connecting cap (8) is attached by spokes (19) to a supporting ring (13) which supports the protective cone (12) from the inside. When the protective cone (12) is subjected to radial loads, for example if the driveshaft is stepped on unintentionally, the purpose of the above measure is to prevent the protective cone (12) from contacting the components of the universal joints (2, 2') which it covers. This measure ensures that in order to make the components of the universal joint (2, 2') accessible, for example for the purpose of sliding on a power take-off shaft, the protective cone can be made to be sufficiently resilient in the direction of the longitudinal axis, while at the same time being capable of accommodating high loads in the radial direction.
