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.

A method for creating a roller spring perch has steps for making a steel frame bracket, procuring snap rings, procuring four bearings, machining a steel cylindrical bearing housing, machining a bearing shaft, assembling the bearing shaft to the bearing housing with the four bearings pressed onto each of two bearing lands, assembling the snap rings in snap ring grooves of the bearing shaft, placing the bearing housing with the bearing shaft and bearings centered through holes in sidewalls of the steel bracket; and spot welding the bearing housing to the sidewalls of the steel bracket.

A fastening arrangement of a vibration damper of a vehicle includes a rubber bearing with a first bush and a second bush, a fastener where via the fastener one of the first bush and the second bush of the rubber bearing is fixed in three degrees of longitudinal freedom with regard to a wheel support of the vehicle or the body of the vehicle, and a measure disposed on the second bush and on the wheel support or on the body of the vehicle where via the measure a degree of rotational freedom of the second bush about an axis of the fastener is blocked by a positively locking block. The positively locking block is formed by a convexly curved cylinder segment of the second bush and a concavely curved cylinder segment of the wheel support or the body of the vehicle that are engagable into one another.

An arrangement for securing a vehicle vibration damper on a wheel support and/or on a vehicle body includes a rubber bearing secured by a fastener, the rubber bearing including at least two rubber bushings. When in an installed position, at least one of the rubber bushings is secured in three longitudinal degrees of freedom relative to the wheel support or the vehicle body, and a rotational degree of freedom of the one of the bushings about the axis of the fastener is blocked by a form-fitting arrangement. The form-fitting arrangement formed by engagement of a nose on the one of the bushings into a recess arranged in a rubber bearing receiving area of the wheel support and/or vehicle body. The nose and the recess are shaped such that the form fitting connection is formed only by installing the fastener, without the need for manually rotating the bushing with a tool.

Provided is a vehicle suspension member securing a strength against external force in a vehicle longitudinal direction. A lower arm includes an arm body, a front bush support part, a rear bush support part, a ball joint support part, a first rib, a second rib, and a third rib. The third rib is disposed in a lateral part connecting the ball joint support part to the rear bush support part. An S-shaped rib center curve of the third rib intersects with a straight line at an intersection. |(1−S2/S1)|≤0.2 is satisfied, where S1 is area of a first region defined by the rib center curve and the first straight line, and S2 is area of a second region.

The positively locking block is formed by a convexly curved cylinder segment of the second bush and a concavely curved cylinder segment of the wheel support or the body of the vehicle that are engagable into one another.

The disclosure comprises a method for producing a sleeve-like passage for a bearing accommodation in a metallic wheel control arm of a vehicle. The method may include placing a wheel control arm end of the wheel control arm onto a pressing plate of a pressing tool; and forming a tapered wall in the wheel control arm end and a circumferential collar around the tapered wall in the wheel control arm end, wherein the forming comprises pressing the wheel control arm end against the pressing plate using a pressing punch, wherein a volume of metal of the wheel control arm end is displaced into a circumferential cavity due to the pressing of the wheel control arm end against the pressing plate,; and perforating the tapered wall to obtain the sleeve-like passage.

A spring strut for a vehicle suspension system includes a spring cylinder defining a cylinder chamber and a spring piston longitudinally displaceable in the spring cylinder. The spring piston subdivides the cylinder chamber into a first and a second outer working chamber. The spring cylinder includes an inner plunger which subdivides a piston chamber formed by the spring piston into a first and a second inner working chamber. The first inner working chamber is simultaneously formed by subdividing the cylinder chamber by means of the spring piston.
