載の自在継手。[Claims for Utility Model Registration] 1. A universal joint with a joint pin pivotably supported in multiple planes in a casing, in particular a tie rod joint for a steering wheel of an automobile, on the one hand, of the joint pin 1; The coupling pin 1 has an end supported in the casing 3 and, on the other hand, the contour of the inner casing wall 31 is configured as follows: (a) in a defined first pivot plane - in its basic position; Starting from - in a first direction E about a defined first rotational center point A and at a distance from this defined first rotational center point A; The first centering point is rotation center point B.
(b) is capable of turning around axes C, C', etc. in another turning plane perpendicular to the defined first turning plane; A universal joint characterized in that the axes C, C'... extend through at least one of the defined first and second rotation center points A, B. 2 The ends of the joint pin 1 supported in the casing 3 have substantially spherical bearings 2a, 2b rigidly connected to each other, and these bearings have center points 21a, 21b. so that the straight line C passing through the joint pin 1 forms an angle with the vertical axis D of the joint pin 1, and the center points 21a and 21b form the first and second rotation center points A and B defined by the basic position of the joint pin 1. , the universal joint according to claim 1, wherein the universal joint is three-dimensionally arranged at intervals from each other. 3. The one support 2a is located within the first pivot plane in which the joint pin 1 is defined, and the other support 2b is
The casing inner wall surface 31 is defined so as to be slidably supported directly or indirectly on the casing inner wall surface 31 when it is rotated about the center point 21b, which is the rotation center point A. 3. The universal joint according to claim 2, which has an at least approximately tulip-shaped profile when viewed in cross-section extending in the pivot plane of the universal joint. 4. The support bodies 2a, 2b are directly slidably supported on the casing inner wall surface 31, and the tulip-shaped contour of the casing inner wall surface is a strongly curved first shape with the casing bottom 32 as the base point. area 31a and a second weakly curved area 31a following this which extends into the casing opening 33.
range 31b, and a first range 31a.
The center of curvature of is formed by one adjacent defined center of rotation B, and the second range 31
The center of curvature of b is the other specified center of rotation A
The radius of curvature of each curved first region 31a corresponds to the radius r of the adjacent spherical support 2a, and the radius of curvature R of each curved second region 31b corresponds to
3. The universal joint according to claim 3, wherein corresponds to the sum of this radius and the distance between the defined centers of rotation A and B. 5 The supports 2a and 2b are connected to the casing inner wall surface 3
1 through a shell-shaped sliding member 4, and the outer shell of this sliding member is connected to the casing inner wall surface 31.
has a tulip-like contour, and its inner contour corresponds to the spherical contour of the supports 2a, 2b, and the tulip-like contours of the casing inner wall surface 31 have the same curvature from the casing bottom 32 to the casing opening 33, respectively. Claim 3 of the utility model registration claim, which is curved at a radius of universal joint.
