Embodiment Construction

[0021] The single figure shows a longitudinal section through a ball joint 1 having a ball journal 2 as a first bearing part and a housing 3 as a second bearing part.

[0022] The ball journal consists of a ball portion 4 having a slightly larger than hemispherical segment shape to which is attached a cylindrical thrust collar 6 of smaller diameter about a journal axis 5 further The reduced sealing flange 7 transitions into a connecting journal 8 .

[0023] The housing 3 is assembled in two parts from a housing upper part 9 and a housing lower part 10 , wherein the housing edges overlap at the connection points and are bonded in a sealing manner.

[0024] The ball part 4 is seated in a correspondingly concave ball socket 11 of the housing lower part 10 with a sliding layer 12 interposed therebetween.

[0025] The sliding layer 12 is designed in two layers and comprises an elastomer casing 13 which is fixedly connected to the ball socket 11 and which can be formed, for example...

Abstract

The invention relates to a ball joint, the ball joint has a ball pin comprising a ball part and a pin, and a housing with the internal supporting the ball pin, the ball pin is supported in the housing so as that the ball pin extends out of a through hole in the housing via the pin part at least partially, and axis around the ball pin can rotate and deflect. The ball part of the ball pin comprises at least a hemispherical ball section, which is mounted in a concave ball scraper of a housing at a sliding layer. The sliding layer is provided with a sliding shell and an elastomer shell. The pin part is connected on the ball gap, the pin part includes a sliding collar with a connection pin guided from an aperture. The collar is symmetrically rotated around a pin axis. The collar is slidably mounted in the housing in a pre-stressed manner by a combination of a sliding ring and an elastomer ring in a direction of the scraper. Therefore, the ball pin can not only twist around the axis of the pin without return force in the whole angle range, but can also perform universal deflection with elastic resistance.

Description

technical field [0001] The invention relates to a ball joint according to the preamble of claim 1 . Background technique [0002] A generally known ball joint of this type comprises a ball journal as a first bearing part and a housing as a second bearing part. The ball journal includes a ball section to which a journal section is attached. The ball journal protrudes with its journal section at least partially from a passage opening in the housing. The ball part is mounted in a correspondingly concave ball socket in the housing in such a way that the ball journal is rotatable about its journal axis and pivotable in the region of the opening for cardan deflection. [0003] In such a ball joint, the sliding surfaces required for this are in direct contact with each other via a lubricant or a sliding layer between the ball part and the housing inner surface, so that vibrations and structure-borne noise can be transmitted directly between the bearing parts, This is disadvantag...
