Embodiment Construction
[0016] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
[0017] refer to figure 1 , shows a schematic view of a device in the form of an air spring damper unit 10 (hereinafter referred to as “air spring unit” 10 ) according to an embodiment of the present disclosure. The air spring unit 10 may include an upper assembly 12 , a lower assembly 14 , a flexible bladder 16 and a shock absorber 18 mounted within the bladder 16 . The shock absorber 18 has a piston rod 20 and a housing 22 . Shock absorbers of this type are well known, and therefore no detailed explanation of the inner workings of the shock absorber 18 itself will be provided.
[0018] Housing 22 of shock absorber 18 is coupled at one end to lower assembly 14 . A rod 18a of the shock absorber 18 slidably ex...

The present disclosure relates to an air spring apparatus for use with a cabin of a vehicle. The apparatus has an upper assembly, a lower assembly, a shock absorber, a bladder, a flexible bumper element and a control element. The shock absorber has a piston rod protruding therefrom and extending through the other one of the upper and lower assemblies. The bladder is attached to the upper and lower assemblies. The flexible bumper element is secured to the piston rod adjacent one of the upper and lower assemblies, and secured to the other one of the upper and lower assemblies. The control element is secured to the flexible bumper element at a first end, and to a valve at a second end, and controls operation of the valve. The flexible bumper element can flex in response to torsional or tilting forces experienced by the one of the upper and lower assemblies, to thus help to limit these forces from being imparted to the control element.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 14 / 849,005, filed September 9, 2015 and also claims the benefit of US Provisional Patent Application No. 62 / 055,004, filed September 25, 2014. The entire disclosure of the above application is hereby incorporated by reference. technical field [0003] The present disclosure relates to air suspension units for adjusting the height of the cabin of a motor vehicle, such as a truck, and more particularly to an air suspension unit having a subsystem built into the air suspension unit that can be based on A relative change in position between the upper and lower assemblies of the air suspension unit causes internal valves to open and close without being affected by tilting or twisting motion of the upper assembly relative to the lower assembly. Background technique [0004] The statements in this section merely provide background information related to th...
