Abstract: A spring plate, especially for a MacPherson strut unit, having an axial support surface for the final turn of a helical spring. The helical spring is centered by radial centering surfaces in the area of the circumferential contour of the final turn. The centering surface is divided into individual, partial centering surfaces, which come to rest against the circumferential contour of the helical spring.

Abstract: A spring strut comprises a pneumatic spring and an oscillation damper and is fitted between a vehicle body and a wheel of a vehicle. The oscillation damper has a piston rod movable on an axis and a container concentric to the axis. The pneumatic spring has a spring chamber delimited by a rolling bellows which is firmly connected to the receptacle and to the container or a rolling-contact piston fixed to the container. An end wall that is in operative connection with the oscillation damper is acted upon on one side by the pressure in the spring chamber and has an effective area that extends obliquely to the axis of the oscillation damper and exerts a transverse force that is dependent on the pressure in the spring chamber and is perpendicular to the axis.

Abstract: A vibration damper for a motor vehicle is taught, which vibration damper has a cylinder tube in which a piston rod which is centered by a piston rod guide can move axially. A container tube encloses the cylinder tube, and the container tube is made of a material which has a significantly higher coefficient of thermal expansion than the material of the cylinder tube. Aluminum is an example if the container tube material. A compensation device compensates for the length difference between the cylinder tube and the container tube at temperatures below and above the temperature at which the vibration damper is manufactured. The container tube is characterized by the fact that preferably at least two expansion beads are formed in the wall of the container tube. The expansion beads compensate for thermal changes in length of the container tube and hold the cylinder tube under a bias with respect to the container tube over the entire range of operating temperatures.

Abstract: Fastening device on the outer tube of a shock absorber, comprising a receptacle for the connection to a vehicle axle and, optionally or in combination, additional mountings for a roll stabilizer and for brake hoses, whereby the connection and the additional mountings are at a distance from one another, characterized by the fact that the receptacle and the mountings are components of a one-piece fastening device, whereby the distance between the receptacle and the additional mountings is bridged by a connecting web.
