An impact damper ( 7 ) with at least one damper unit ( 8, 9, 10, 11 ). The damper unit ( 8, 9, 10, 11 ) includes at least one elastomer spring element ( 15 ), at least one fluid-filled primary chamber ( 24 ), and at least one fluid-filled secondary chamber ( 27 ), as well as one nozzle opening ( 26 ) connecting the two chambers ( 24, 27 ), wherein the fluid can be displaced during spring deflection of the elastomer spring element ( 15 ) from the primary chamber ( 24 ) into the secondary chamber ( 27 ). The impact damper ( 7 ) includes a damper unit ( 8, 9, 10, 11 ) has the shape of a rotational toroidal or an annular body. The impact damper of the invention is suitable, in particular, for high-end damping applications, for example the wheel suspension of automobiles, and more particularly for overcoming such divergent requirements as an early force buildup, a uniform energy dissipation with a long stroke, and a high energy absorption. The impact damper reduces the repair frequency of connecting elements which may become necessary, for example, when excess stress is applied to the chassis; or optionally, the weight and the costs of the connecting components can be reduced.
