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.

Spring plate

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.
