The air spring provided by the present application can ensure ride comfort of the vehicle under a low-load condition and avoid damage to other components resulted from a subsidence of a vehicle body under a heavy-load condition.

Disclosed herein is a shock absorber device having a structure for constant-speed operation. The shock absorber device having a structure for constant-speed operation includes: a body configured such that an inner cylinder having a plurality of orifices is concentrically accommodated inside an outer cylinder and a piston rod and a spring are connected to a piston that slides in the inner cylinder; an accumulator disposed in a flow passage communicating with the orifices and configured to damp a working fluid; and an adjusting means configured to adjust absorbing force and repelling force to a set range via the piston rod. A connection rod is angle-adjustably provided at at least one end of the body, and the connection rod is connected via a worm gear and an adjusting bolt.

A bearing system including a frequency independent damper assembly and a bearing pad assembly. The damper assembly includes a housing, a plunger, a moving central post and a support spring. The plunger is movable within a housing to define a first primary damper cavity and a second primary damper cavity. The moving central post has defined therein a fluid channel for a pressurized working fluid flow. The support spring includes a plurality of flexible elements coupled to the housing and disposed radially outward of the first and second primary damper cavities. The support spring defines first and second accumulator cavity. A flow-through channel couples the first accumulator cavity to the second accumulator cavity. In an embodiment, the flow-through channel may be disposed within the moving central post. The bearing pad assembly includes a bearing pad including a plurality of bearing pad orifices coupled to the fluid channel in the moving central post.

The invention relates to a hydraulic mount, including a hydraulic mount for mounting a motor vehicle engine on a vehicle body. In embodiments, the hydraulic mount includes: a hydraulic module with a support spring that supports a mount core, surrounds a working chamber, and is supported on an outer ring on which a cover is fixed, a compensation chamber which is separated from the working chamber by an intermediate plate and is delimited by a compensation membrane, wherein the compensation chamber and the working chamber are filled with a damping liquid and are connected with each other in a liquid-conducting manner via a damping channel arranged in the intermediate plate; and a housing accommodating the hydraulic module. In embodiments, the outer ring includes a radial projection with a rubber-lined axial abutment surface and a non-rubber-lined radial outer surface.

A device for switching medium and/or high voltages has a spring-loaded drive for driving a kinematic chain. At least one energy storage spring and at least one damping element for generating a drive movement with specific drive characteristics are included. The at least one damping element is an active damping element. The damping is actively determined during switching or it is predetermined, in particular depending on environmental variables and/or the type of switching situation, by changing the settings of the at least one damping element.
