  • Patent number: 6846240
    Abstract: Disposed around a universal joint (12), which comprises a first and a second substantially rigid joint body (14, 28), is a rim (40) of loop-shaped flexible coupling elements (42), which are each looped around one first molded piece (50) and one second molded piece (52). The first molded pieces (50) are connected rigidly to a flange (22) on the first joint body (14) and disposed between second molded pieces (52). The second molded pieces (52) are connected firmly to a counter-flange (34), which forms part of a rotational body (62). The latter forms one end of a torque transmission chain, the other end of which is the second joint body (28). The first joint body (14) has a tubular piece (16), which encloses the second joint body (28) and has an outer lateral surface (18) of circular cross section, against which the flexible coupling elements (42) are supported in radial direction.

  • Patent number: 6343777
    Abstract: A suspension lug has a ring shaped elastomer body in which two fixing parts are arranged opposite each other, and a flexible insert shaped like a loop which is embedded in the elastomer body in such a way that it transmits tensile forces from one fixing part to the other when the suspension lug is subjected to tensile loading. At least one of the fixing parts has attachment areas on which the insert is hung in such a way that the insert extends essentially radially away from this fixing part. As a result, the structural height of the suspension lug is relatively small.

  • Patent number: 6315670
    Abstract: A joint body includes at least one loop package and collar bushings each having a bushing member and a first collar formed integrally thereon. The bushing members of the collar bushings are passed through the loop package, and the collars thereof axially support a first loop package side. A second collar axially supports a second loop package side and is axially joined with each bushing member. The collar bushing has at an end of the bushing member remote from the first collar a radial outer catching arrangement. A radial inner catching arrangement is provided on the second collar which forms a snap connection together with the radial outer catching arrangement. The loop package is at least partially embedded in a rubber elastic jacket.
