A decoupling bearing for a suspension strut or a pneumatic suspension strut may include a suspension strut cup and a connecting element that can be connected to a vehicle body. A damping element may be arranged between the suspension strut cup and the connecting element. The suspension strut cup may be connected to the connecting element by the damping element. Further, the damping element may be adhesively bonded to the connecting element and the suspension strut cup in a force-transmitting manner, and/or the damping element may be adhesively bonded to the connecting element and an intermediate element in a force-transmitting manner. The intermediate element may be connected to the suspension strut cup.

A dirt shield for shock absorbers having a piston assembly and a cylinder member with a metal dirt shield cap connected to a rod of the piston assembly. A plastic dirt shield bracket is adapted to be fixed to the metal dirt shield cap and includes a first portion and a second portion hingedly connected to one another. A dirt shield tube is connected to the plastic dirt shield bracket.

A suspension device includes: a hydraulic damper including a rod provided with a valve for generating a hydraulic pressure when the rod is displaced between a first liquid chamber and a second liquid chamber; and an electric damper configured to electrically displace the rod by an actuator. The electric damper includes: an outer cylinder; an inner cylinder; a piston provided on the rod and configured to stroke in the inner cylinder; and a communication passage disposed inside the inner cylinder at a central portion where the piston strokes. The communication passage establishes communication between the first liquid chamber at one axial end side of the piston and the second liquid chamber at another axial end side of the piston.
