Abstract
A protective device for a driveshaft (1), with two universal joints (2, 3) has a protective cone (6) associated with the first universal joint. The protective cone (6) has an extension in the form of a cone portion (14). A sleeve (15) is received in a rotationally fast way in the cone portion (14). The sleeve (15) cooperates with an adapter ring (21). The adapter ring (21) is stationarily secured to an agricultural implement. The sleeve (15) is positioned on the adapter ring (21). The sleeve has inwardly directed splines which engage correspondingly distributed grooves (23) in the outer face of the adapter ring (21) which achieve a rotationally fast connection. The protective device also includes a first protective tube connected to the first protective cone (6). The first protective tube is associated with a second protective tube of the second universal joint in a rotationally fast way. The second tube is firmly connected to the second protective cone by an attaching cap. The attaching cap is secured to the second universal joint so that the entire protective device remains rotation free.
