全部で３つの半球状支持殻体が必要である。Prior Art Consisting of two hemispherical support shells, the inner hemispherical support shell has two hemispherical support shells.
A grease-lubricated ball joint is known from Japanese Patent Publication No. 52-41836, which has a support shell consisting of two parts and having a plurality of fins on its outer surface for support in a joint housing. A thin inner shell of stiff elastic plastic without lubricating grooves is inserted into a support shell of soft elastic plastic with fins. By only locally supporting the fin in the coupling housing, the support surface of the underlying support shell is locally deformed in various ways, and the support clearance or grease film is such that the support surface of the fin is It is the smallest where it is attached. This means the formation of lubricant pockets in the intermediate region and a gradual transition from the intermediate region to the load-bearing area. To achieve this result, in the known ball-and-socket joint, two mutually engaging support shells made of soft and stiff elastic plastics are first connected to each other, and then a second hemispherical support shell is connected to the other. and the ball shaft must be assembled into the joint housing. A total of three hemispherical supporting shells are therefore required in this known ball and socket joint.

持つている。 A one-piece self-lubricating plastic support shell is used, which has an annular pocket in the equatorial region of the ball head for containing a lubricant reservoir. As a result, a ball joint in which a spherical ball head is held by a pair of upper and lower support areas of a support shell is known from German Patent Application No. 23 26 018. . In this known ball joint, the ball head has a greater clearance in the equatorial plane than in the direction perpendicular to the equatorial plane due to the annular pocket.

おそれもない。Effects of the Invention According to the invention, during assembly, the area of the fins of the inner support shell is subjected to an initial stress between the joint housing and the ball head, so that the inner support shell made of soft elastic plastic The material of the body fins is extruded into the area between the fins, ie the intermediate area, and moves this intermediate area away from the ball head, thereby automatically forming a flat lubricant pocket. Thus, according to the present invention, by making the wall thickness of the fin of the soft inner support shell larger than the width of the gap between the joint housing and the ball head, a flat lubricant pocket is eliminated during assembly of the ball joint. Since this occurs automatically, it is not necessary to previously provide such a lubricant pocket on the inner surface of the inner support shell, which can be formed spherically, making the support shell cheaper to manufacture. In addition, the intermediate area between the fins creates a lubricant pocket of sufficient size, regardless of the load on the ball joint, so that sufficient lubrication of the sliding area between the ball head and the support shell is achieved. will be carried out. Moreover, since the depth of the lubricant pocket gradually decreases to the area where the fins are located, there is no fear that the lubricant film will break at the edge of the pocket.

リース溜め７として利用することができる。 The ball head 3 of the ball shaft part 2 is fitted into the joint housing 1 with an inner hemispherical support shell 4 and an outer hemispherical support shell 5 interposed therebetween. Since there is a flat disk 6 between the inner support shell 4 and the coupling housing 1, the space between the ball head 3 and this disk can be used as a grease reservoir 7.

れるような潤滑膜の破裂を恐れる必要はない。 The inner support shell 4 is provided with spaced apart fins 8 on its outer surface, by means of which the inner support shell 4 is supported on the coupling housing 1. The wall thickness S 1 of the support shell 4 in the area of these fins 8 is slightly larger than the gap width between the coupling housing 1 and the ball head 3 in this area in the unassembled state. As a result, the fins 8 are prestressed in these load-bearing areas during assembly. The extrusion of material takes place in the areas between the fins 8, in which the wall thickness S 2 of the support shell 4 is only approximately half as large as the wall thickness in the fin areas. Due to the extrusion of material from two adjacent fins 8, the intermediate region is moved away from the ball head 3 in the direction of the coupling housing 1 and forms flat lubricant pockets 9, which lubricant pockets form the ball head 3. When moving, it is filled with grease from the grease reservoir 7. Since the lubricant pocket 9 has a very gradual transition to the load-bearing area under the fin 8, there is no need to fear a rupture of the lubricant film as occurs in machined lubricant grooves.
