Mounting system for the elastic mounting of a strut or a vibration damper

A mounting system for the elastic mounting of a strut or a vibration damper on a vehicle body in a receiving cup on a body side, the mounting system comprising:

• a unit that is insertable into said receiving cup;
• a fixing device that secures the unit from being withdrawn from the receiving cup, the unit having a mounting unit and a piston rod of the strut or the vibration damper;
• wherein the mounting unit has at least one elastomer mount for resiliently mounting the piston rod, the elastomer mount having a core for receiving the piston rod and an elastomer body, and having at least one ring element that is a separate part or is non-positively, positively and/or materially connected to the elastomer body;
• wherein the unit and the fixing device are configured for insertion into the receiving cup from a side facing away from the body and, in an inserted state, the fixing device engages behind an undercut formed on the receiving cup;
• wherein the at least one ring element is supported on the fixing device, and the elastomer body is prestressed and presses the ring element against the fixing device;
• and
• wherein the mounting unit has an additional spring receiving device, the additional spring receiving device and the ring element have intermeshing positively connected contours which are movable from a first position into a second position when the elastomer mount and the fixing device are inserted into the receiving cup.
