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.

The invention relates to a preassembly device for preassembling an air spring on a body (e.g., a car body) that has an assembly interface. Embodiment of the preassembly device include a centering member for centering the preassembly device on the assembly interface, and a connector for connecting to an air spring. With embodiments, the preassembly device further includes a carrier (or support element) extending away from the preassembly device. A seal provided on the carrier for sealing a discharge opening of the body may be provided at the assembly interface, wherein the centering member may be configured for aligning the seal at the discharge opening. The invention provides a device that can provide a low-cost and simple sealing of the outlet openings in the area of the mounting interface.

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.

A pneumatically operable adjusting device (1) is provided for acting on a spring device (5) of a spring damper device (3) having a tubular body (2), with a tubular piece-shaped housing (4) which is designed to surround the tubular body (2) and has a passage (6) passing through a peripheral wall of the housing (4), and the adjusting device (1) has an adjusting nut (9) with an internal thread (10) which is attached to an external thread (11) of a tubular body (2), 37) of the spring damper device (3) can be brought into screw engagement, the housing (4) being designed for releasable abutment against the adjusting nut (9) and having an inner recess (7) for forming a pressure chamber (8) which is in fluid connection with the passage (6) and the inner recess (7) forming a pressure wall (24), the fluid admission of which causes a force acting on the housing (4) in the axial longitudinal direction and the housing (4) has an abutment surface (54) designed for spring force admission by the spring device.

A device for adjusting the height of a motor vehicle body (3), including an actuator (1) for actuating a vertically adjustable spring seat of a suspension spring (15), characterized in that a pin (4) is provided for connecting the device to the vehicle body (3), an actuator side pin section (10) extends through a support eye (6) in a support plate (7) of the actuator (1), and an elastomer support (2) is disposed at least on the face of the support plate (7) facing the vehicle body, between the support plate (7) and a flange (9) provided on the bolt (4).

A method for producing a mounting arrangement for a link of a motor vehicle suspension that is or can be pivotably mounted on a subframe of the motor vehicle, having the following steps: providing the subframe, which has a first and a second mounting flange for mounting the link; providing at least one intermediate product of a bracket; integrally joining the intermediate product to a mounting flange of the subframe by welding; forming an elongated hole in the intermediate product by punching of the same; and forming at least one stop on the intermediate product for an adjusting eccentric for chassis adjustment by stamping the intermediate product.

A motor vehicle includes a bodywork structural element and a running gear, such as a vehicle back end, that includes at least one arm. The at least one arm includes a top attachment end that is received in a sheet metal clevis supported on a bottom surface of a floor of the bodywork structural element. The attachment end includes at least one transverse tubular sleeve that is received with reduced play between two parallel flanks of the clevis, and an attachment screw capable of passing through two coaxial bores of both flanks and the transverse tubular sleeve to enable attachment of the attachment end into the clevis. The clevis guides the attachment end into a position for aligning the bores of the flanks and the sleeve.

A suspension for a vehicle provides a configuration in which a bolt is screw-fastened to a stud part of a ball joint in a state in which the stud part is inserted into a knuckle, an outer diameter of the stud part is increased at the time of fastening the bolt so that the stud part and the knuckle are coupled to each other. Thus, a position of a hard point corresponding to a center of the ball joint is not changed when the ball joint is coupled by the bolt.

End member assemblies include a first end member and a second end member. The first end member includes a first end member wall with a first side wall portion and a first flange wall portion. The first flange wall portion includes a plurality of attachment passages extending therethrough. The second end member includes a second end member wall with a second side wall portion and a second flange wall portion. The second end member includes attachment studs disposed along the second flange wall portion. The first and second end members are positioned axially coextensive with one another with the attachment studs extending through corresponding attachment passages. A stud head is unitarily formed along the attachment studs with the stud head abuttingly engaging the first flange wall portion thereby retaining the first and second end members in an assembled condition.
