Abstract
A telescopic strut, in particular for a device for lifting loads, in particular for a hanger for vehicles or vehicle parts, wherein the telescopic strut consists of an outer tube and an inner tube guided therein, wherein the inner tube is movable longitudinal direction in the outer tube, where a number of sliding shoes are attached to the outer tube to guide the inner tube, where the sliding shoes have each been introduced from the outside into an opening in the wall of the outer tube and protrude inwardly to guide the inner tube such that the telescopic strut, which is structurally simple and therefore inexpensive to produce, has good sliding properties, has little guide play and is easy to maintain.
Claims9
A telescopic strut for a stabilizer for a device for lifting loads, the telescopic strut comprising:
- an outer tube;
- an inner tube guided in the outer tube, the inner tube being movable in a longitudinal direction in the outer tube;
- a plurality of sliding shoes attached to the outer tube for guiding the inner tube, each sliding shoe of the plurality of sliding shoes being introduced from an outside into a respective opening of a plurality of openings in a wall of the outer tube and protruding inwardly for guiding the inner tube;
- and
- a plurality of spacers, each spacer of the plurality of spacers being introduced between an outer side of the outer tube and a bearing surface of a respective sliding shoe of the plurality of sliding shoes;
- wherein the plurality of sliding shoes each have a substantially T-shaped cross section,
- wherein a part of each sliding shoe of the plurality of sliding shoes is led through the respective opening of the plurality of openings in the wall of the outer tube from the outside,
- wherein an overhanging part of each sliding shoe of the plurality of sliding shoes forms the bearing surface of the sliding shoe, bears against a respective spacer of the plurality of spacers bearing against the outer tube, and is connected in a screwed manner to the outer tube in a region of the bearing surface of the sliding shoe,
- wherein two groups of the plurality of sliding shoes are arranged at two spaced-apart regions of the outer tube respectively, and
- wherein within each of the two spaced-apart regions,
- at least four sliding shoes of the two groups of the plurality of sliding shoes are arranged in an annularly distributed manner around a periphery of the outer tube,
- only one sliding shoe of the two groups of the plurality of sliding shoes is arranged at a first lateral side of the outer tube,
- only one sliding shoe of the two groups of the plurality of sliding shoes is arranged at a second lateral side of the outer tube,
- two sliding shoes of the two groups of the plurality of sliding shoes arranged at a first transverse side of the outer tube extend a first depth into the outer tube, and
- two sliding shoes of the two groups of the plurality of sliding shoes arranged at a second transverse side of the outer tube extend a second depth into the outer tube, the second depth being different from the first depth.
