摘要： Pneumatic spring comprises a rolling bellows, one end of which is attached to a connector part. The connector part has a profiling, which cooperates with a clamping ring to hold the rolling bellows in position. The profiling is in the form of a shoulder, against the axial surface of which the rolling bellows rests, where the rolling bellows is deformed axially by the clamping ring onto a radial clamping surface.

摘要： A vibration damper with amplitude-selective damping force includes a cylinder containing a damping medium, a piston rod which is axially movable in the cylinder, and a piston assembly arranged for axial movement in the damping medium, the piston assembly being connected to the piston rod and dividing the cylinder into a working space around the piston rod and a working space opposite the piston rod, the piston assembly includes a piston body having connecting channels for opposite directions of flow between the working spaces, and valve disks which open the channels in respective opposite directions. A pilot assembly includes an axially movable shifting ring which controls a flow connection between the working spaces as a function of movement of the piston rod, and a pair of stop surfaces which limit axial movement of the shifting ring, wherein the stop surfaces are independent of the piston body and the valve disks.

摘要： Vibration damper with amplitude-selective damping force that includes a piston rod, which is guided with freedom of axial movement in a damping medium-filled cylinder. The piston rod carries a piston arrangement, which divides the cylinder into a working space on the side of the piston with the piston rod and a working space on the side of the piston opposite the piston rod, where a flow connection, which, as a function of the movement of the piston rod, determines a damping force by means of a switching ring, which moves axially between two stop surfaces, in conjunction with at least one axially movable valve ring in a switching ring groove. The switching ring cooperates with one stop surface to form the boundaries of an annular space adjacent to the working space on the piston rod side and with another stop surface to form the boundary of an annular space adjacent to the working space on the side of the piston opposite the piston rod. The axial extension of the switching ring groove for the axially movable valve ring is large enough to guarantee that the damping medium can flow around the valve ring over a relevant stroke range of the piston rod.
摘要翻译：具有振幅选择阻尼力的振动阻尼器包括一个活塞杆，该活塞杆在阻尼介质填充气缸中被轴向自由移动。活塞杆带有活塞装置，该活塞装置将活塞与活塞杆分隔成活塞侧的工作空间，活塞侧与活塞杆相对的工作空间分开，流动连接活塞杆运动的功能决定了通过在切换环槽中的至少一个可轴向移动的阀环的两个止动表面之间轴向移动的开关环来确定阻尼力。开关环与一个止动表面配合以形成与活塞杆侧上的工作空间相邻的环形空间的边界和另一个止动表面，以形成与活塞侧面上的工作空间相邻的环形空间的边界与活塞杆相对。用于可轴向移动的阀环的开关环槽的轴向延伸足够大，以确保阻尼介质可以在活塞杆的相关行程范围内围绕阀环流动。

摘要： A vibration damper with amplitude-selective damping force includes a piston rod carrying a piston arrangement axially movably arranged in a cylinder and dividing the cylinder into two working spaces. A flow connection is present between the working spaces and controlled by an axially movable switching ring which cooperates with a working surface which faces the ring to define a pilot opening cross section. A bypass channel with at least two connecting openings to the flow connection is provided hydraulically in parallel to the flow connection. At least one connecting opening upstream of each of two stop surface of the switching ring. A check valve arrangement separates the bypass channel and the flow connection from each other in the different flow directions as a function of the movements of the piston rod, the check valve arrangement having two check valves which close in opposite directions.
