ABSTRACT:
A protection arrangement for a double universal joint (1) for drives of agricultural implements has a first protection element (11), an annular second protection element (15) and a third protection element (18). The first protection element (11) has first holding projections (14) circumferentially distributed on its outer circumference (13) close to the first front edge. The first holding projections (14) project beyond the outer circumference (13) and form at least over a circumferential edge portion, distanced to the first front edge, a groove. A support tab projects beyond the first front edge. The second protection element (15) has second holding projections (17) circumferentially distributed on its outer circumference close to the second front edge. The second holding projections (17) project beyond the outer circumference and form, at least over a first circumferential edge area close to the second front edge, a second groove. An undercut portion is formed over a second circumferential edge area distanced to the second front edge. The third protection element (18) has holding portions at both ends. The holding portions include a number of first through holes (20) or second through holes, respectively. The through holes engage the holding projections (14, 17), corresponding in number to the first holding projections (14) and second holding projections (17).
