Single-tube vibration damper and dome bearing for motor vehicles

A single-tube oscillation damper for a motor vehicle, the single-tube oscillation damper comprising:

• a damper tube that extends in a longitudinal direction and is at least partially filled with damping fluid, wherein a piston rod is movable back and forth in the damper tube, wherein an operating piston is movable with the piston rod;
• an end remote from the piston rod for bearing in a dome bearing, wherein the end comprises:
• a first portion and a second portion, the first portion being longitudinally closer to the damper tube than the second portion, wherein the first and second portions have different outer diameters,
• a transition region from an outer diameter of the damper tube to the outer diameter of the second portion, and
• a support region disposed in the transition region;
• a stop plate disposed on the support region;
• and
• a damping element disposed on the stop plate at a side facing the end, the damping element being disposed within the dome bearing such that the dome bearing extends along an entire longitudinal length of the damping element radially exterior to the damping element.
