Supporting ring and assembly with a supporting ring
A supporting ring for an air-suspension strut. In embodiments, a support ring has a central longitudinal axis and includes a wall. In a radially inward direction, the wall has or forms an internal-abutment geometry that projects in the radial direction, and/or, in a radially outward direction, the wall has or forms an external-abutment geometry that projects in the radial direction.
1 . A supporting ring for an air-suspension strut, comprising:
a central longitudinal axis; and
a wall;
wherein, in a radially inward direction, the wall has or forms internal ribs or internal inwardly curved portions that project in a radial direction, and, in a radially outward direction, the wall has or forms external ribs that project in the radial direction; wherein respective internal ribs or internal inwardly curved portions are in alignment in the radial direction with corresponding external ribs, or the respective internal ribs or internal inwardly curved portions are offset equidistantly in a circumferential direction in relation to the corresponding external ribs; wherein both the internal ribs or internal inwardly curved portions and the external ribs run in an axial direction; and a number of internal ribs or internal inwardly curved portions is equal to a number of external ribs.
2 . The supporting ring as claimed in claim 1 , wherein the internal ribs or internal inwardly curved portions can be brought into abutment against a damper tube of an air-suspension strut for radial-support purposes, and/or the external ribs can be brought into abutment against a piston of an air-suspension strut for radial-support purposes.
3 . The supporting ring as claimed in claim 1 , wherein the supporting ring has a latching structure that is arranged continuously in the circumferential direction around the central longitudinal axis, projects in the axial direction, and can engage with a piston.
4 . The supporting ring as claimed in claim 3 , wherein the latching structure comprises a toothing formation.
5 . The supporting ring as claimed in claim 1 , wherein the supporting ring has a receiving flange that extends in the radial direction and forms an abutment surface for at least one sealing ring.
6 . The supporting ring as claimed in claim 5 , wherein the receiving flange has a separating device that projects in the axial direction and separates a radially external sealing-ring mount from a radially internal sealing-ring mount.
7 . The supporting ring as claimed in claim 1 , wherein the supporting ring has a supporting flange that extends in the radial direction from the wall to a radial edge, and a sleeve of an air-suspension strut is configured to engage around the radial edge.
8 . The supporting ring as claimed in claim 1 , wherein, on an outer circumference, the supporting ring has depressions that run in the axial direction.
9 . The supporting ring as claimed in claim 8 , wherein the depressions are open at at least one respective axial end, and/or are designed to be free of undercuts in the axial direction.
10 . The supporting ring as claimed in claim 9 , wherein the depressions are fully open.
11 . The supporting ring as claimed in claim 1 , wherein a distance is formed in the axial direction between, on one hand, the internal inwardly curved portions or the external ribs; and, on another hand, an axial wall end.
12 . The supporting ring as claimed in claim 1 , wherein with an aligned configuration, a radial force can be transmitted directly to the internal ribs or internal inwardly curved portions and, with an offset configuration, tolerances with surrounding components are easier to compensate for compared to said aligned configuration.
13 . An assembly comprising
the supporting ring as claimed in claim 1 ,
at least one sealing ring, and
the air-suspension strut with a damper tube,
wherein the supporting ring butts against the damper tube of the air suspension strut via the internal ribs or internal inwardly curved portions.
14 . A supporting ring for an air-suspension strut, comprising:
a central longitudinal axis; and
a wall;
wherein, in a radially inward direction, the wall has or forms internal ribs or internal inwardly curved portions that project in a radial direction, and, in a radially outward direction, the wall has or forms external ribs that project in the radial direction; wherein respective internal ribs or internal inwardly curved portions are in alignment in the radial direction with corresponding external ribs, or the respective internal ribs or internal inwardly curved portions are offset equidistantly in a circumferential direction in relation to the corresponding external ribs; wherein both the internal ribs or internal inwardly curved portions and the external ribs run in an axial direction; and each external rib is either in radial alignment with a respective internal rib or internal inwardly curved portion or offset circumferentially by half an angular extent between each adjacent internal ribs.
