A vibration damper for a motor vehicle with a support spring, includes a damper tube with a longitudinal extension axis A, a spring disk, a protective insert, and a protective accordion boot which has a first end portion and a second end portion, wherein the protective accordion boot is secured at least indirectly to a piston rod by its first end portion, and wherein the protective accordion boot encloses damper tube in circumferential direction by its second end portion. The protective insert has at least one radially outwardly extending supporting portion, wherein the protective accordion boot is axially supported by the second end portion thereof at the supporting portion of the protective insert accompanied by a defined axial pre-loading, and wherein, with respect to the longitudinal extension axis A of the damper tube, the supporting portion extends radially beyond the inner diameter d of an end coil of support spring supported at the spring disk.

Vibration damper for a motor vehicle

Mounting assembly for a vibration damper, comprising at least one aligning surface on the vibration damper side, which is in working connection with an opposing surface on the vehicle side at least during the installation of the vibration damper in a receiving opening in the vehicle. The at least one aligning surface and the opposing surface rotationally align the mounting side with the vehicle side. The aligning surface is arranged on a mounting cap with torque-transmitting element, and with at least one axial support surface for cooperation with the opposing surface on the vehicle side. The mounting cap prevents the vibration damper from falling out of the mounting assembly through the use of a carrier on the mounting side, to which the vibration damper is attached, this carrier having a retaining element in the form of a tongue which engages an opening in the mounting cap.
