Abstract: A twist beam for a suspension of a motor vehicle comprises a body-side inner part having a bearing-receiving section for receiving a body-side bearing, and a wheel carrier-side outer part having a bearing-receiving section for receiving a wheel carrier-side bearing, the outer part and the inner part being separate components which are made of different materials and are firmly connected to each other.

Abstract: A ball joint includes a carrier part and a hollow ball which is a component separate from the carrier part and is fixed on the carrier part.

Abstract: In a ball joint with a housing, a ball stud which includes a ball head mounted in the housing, and with a sealing bellows which includes a ring-shaped housing-side connecting region, it is provided that at the housing a ring-shaped channel is provided, in which the housing-side connecting region is accommodated, wherein the outer radius of the channel at the channel bottom is greater than the outer radius at the free edge of the channel, and on the housing-side connecting region of the sealing bellows at least one holding element made of a rigid material is provided, which in particular in a top view in longitudinal direction of the ball stud is at least partly covered by the free edge of the channel.

Abstract: A method of fastening a sealing bellows to a ball joint as well as to a ball joint is shown comprising a joint housing, a ball stud pivotally received in the joint housing, and a sealing bellows which, related to a joint axis, comprises a first axial end of the bellows resting against the ball stud and a second axial end of the bellows fastened to the joint housing, the joint housing for fastening the sealing bellows comprising a seat of the bellows forming a radial stop as well as an axial stop for the second axial end of the bellows, and wherein a closed retaining ring is provided which is spaced from the joint housing and acts upon the sealing bellows in radial inward direction against the seat of the bellows.

Abstract: This invention relates to a joint housing (10) of a ball joint (12), comprising a sheet-metal part (14) for accommodating a ball head (16), which is substantially rotationally symmetrical with respect to a joint axis (A) and includes a circumferential wall portion (18), wherein the circumferential wall portion (18) includes a housing opening (26) at an axial end (24), through which a joint pin (28) can extend, wherein the sheet-metal part (14) is formed with two layers at this axial end (24) of the circumferential wall portion (18). Furthermore, the invention also relates to a method for mounting such joint housing (10) on a carrier element (34).

Abstract: A ball joint which comprises a joint housing, a bearing shell received in the joint housing, and a ball stud having a ball head arranged for pivoting movement in the bearing shell. The ball head is prestressed by a spring system substantially in the direction of a longitudinal axis of the ball stud against the joint housing. The spring system is composed of spring elements connected in parallel and/or in series, at least one spring element of the spring system being made of a polymer material or of an elastomer material.

Abstract: An improved ball joint for use in a motor vehicle steering or suspension system includes a housing, a bearing disposed in the housing, and a ball stud supported within the housing by the bearing. The bearing includes at least a first bearing member formed from a first material and a second bearing member formed from a second dampening material attached to at least a portion of an outer surface of the first bearing member. The first bearing member has a bidirectional slot formed therein which is configured to allow the ball stud to articulate in a first direction and restrict and dampen articulation in a second direction which is generally transverse to the first direction.
