22Π 481 1 2 Support surfaces on inwardly facing projections Claim: the spherical-spherical shell of a ball-and-socket joint, which is interrupted neither in the axial direction nor in the circumferential direction by slots or the like, is formed from a single shell and that to achieve an expensive casting made of elastic material with radial flexibility at the edges of the ball on opposite sides Hollow shell open on the sides in one or each of which has the corresponding ofraum, the two axially spaced, open end of the cavity enclosing end flanges through cutouts interrupted circumferential areas of the ball socket, hen with support surfaces for the bearing ball, which has a technical We continue to achieve a.
wherein the support surfaces of one circumferential row 10 The invention is in the following based on the srnematiaxial alignment of the recesses of the other Umscher drawings in an exemplary embodiment initial row, thereby clarified. It shows .
indicates that all hollow spherical F i g. 1 a telescopic shock absorber or e.ne gas-arched support surfaces on inwardly pointing springs with spherical shell projections (14, 15) arranged at both ends which neither in axial direction 15 according to the invention,.
device still in the circumferential direction through slots Fig.2 a view in the longitudinal direction of one of the od. The like. Interrupted spherical shell formed spherical shells and are and that to achieve a radial according to Fig. 3 an axial section along the line X-X in yield at the edges of the spherical shell in FIG. 2 of the spherical shell. one or each of the corresponding open 20 corresponding to FIG. 1 is a telescopic shock absorber End face enclosing the end of the cavity or a gas spring 10 with corresponding (n.cnt surfaces of the spherical shell an annular groove (17) formed) components of a vehicle by means of det is geigelenken 11 and 12 connected. From Fig. 2 and 3 it can be seen that every ball 25 shell, which is advantageously made of plastic, such as. B. nylon or made of polypropylene, has a substantially cylindrical, through bore, which is used to hold a ball on its inner The invention relates to a spherical shell of a cage which has a receiving section 13. This articulated joint made of a one-piece casting of elastic 30 receiving section 13 comprises two in the axial section Material only on opposite sides of one another, in the circumferential direction th open cavity, the two axially spaced rows 14 and 15 of spaced apart, circumferential rows that are interrupted by cutouts and are arranged one after the other in the axial direction with support surfaces for the bearing ball stretching, inwardly pointing projections that comprises, wherein the support surfaces of the one circumferential 35 are integrally formed with the spherical shell. the row axially on the recesses of the other um- projections each of a series of projections are jefangsreihe are aligned. because the space between a pair of before-bys a well-known spherical shell of this type (German counterparts to the other dimensions of the axially opposite Utility model 1 960 921) are from Ein über. The projections have inward guide openings on them for the bearing ball outgoing axial 40 ends spherically concave support surfaces 16 erected, Slits are provided, which are used to insert the which together for receiving the ball Bearing ball in the ball socket required refill- both sides open, part-ball-like recess to generate energy. The well-known spherical shell can form on. The reason for the weakening due to the slits in the Rieh- The ball is conveniently placed in the ball direction of the insertion opening only a slight axial snap 45 by pushing it through one of the open withstand the load. Sides press in, with the protrusions 14 or 15 It is also a spherical shell made of a one-piece elastic yielding. If necessary, the ball is the same Cast piece made of elastic material with a too easy to remove in the same way, opposite sides known open cavity, In the opposite side surfaces of the in which the spherical bearing surface around a ball 50 spherical shell, two annular grooves 17 are incorporated, larger in diameter than the actual bearing ku, each of which has the adjacent open end of the gel is formed (French patent specification enclosing recess and thus with a view to 1 232 485). The edge of the spherical shell around the insertion and removal of the spherical Guide opening are formed like a lip, without adjacent projections 14 or 15 a larger one to be interrupted by slits. Because of the greater resilience in the radial direction. At Bc- Larger diameter of the spherical bearing surface may only have a single annular groove 17 on one side as the bearing ball has to be provided with the known ball to allow the insertion of a ball of schale different joint inevitably a game. this side to facilitate. The invention is based on the object of an expediently the spherical shell with auxiliary spherical shell of the type described above, except for a core with two matching, zubilden that while maintaining a simple axially movable away from each other Possibility of mounting the bearing ball by means of plug-in parts, these parts inking mutually in the Kugslschalc the resilience of clashing fingers that make the statements Form axial load in the direction of the insertion openings in the spherical shell and with spherical suitability for the sphere is enlarged. 65 convex ends are provided, which are connected to each other To solve this problem, the corresponding part-spherical surfaces are according to the invention provided that all form a spherically curved spherical shell.
