Abstract
A lead screw nut support arrangement includes a wall having a width and a through hole that passes through the wall. A support bushing passes through the through hole in the axial direction, leaving an amount of play, and having a length greater than the thickness of the wall. The support bushing is supported in the through hole movably in the axial direction. A lead screw nut is also included whose end face adjoins a first end face of the support bushing on the inner side of the wall. The support arrangement also includes a mount that braces a second end face of the support bushing against the lead screw nut such that the lead screw nut is elastically loaded in the direction away from the wall.
Claims15
A lead screw nut support arrangement, comprising:
- a wall having a predetermined thickness and a through hole that passes through the wall;
- a support bushing disposed in the through hole in an axial direction, the support bushing having a length greater than the thickness of the wall such that an amount of axial play exists between the support bushing and the wall so that the support bushing is movable in the axial direction, the support bushing includes a first collar extending radially outward from the support bushing on a first axial side of the wall and comprising a first collar end face, and a second collar extending radially outward from the support bushing on a second axial side of the wall and comprising a second collar end face;
- a lead screw nut having an end face that adjoins the first collar end face of the support bushing;
- and
- a mount that braces the second collar end face of the support bushing with an elastic element positioned between the second collar and the mount such that the lead screw nut is elastically loaded in a direction away from the wall.
A lead screw nut support arrangement that interfaces with a wall having a through hole formed therein, the support arrangement comprising:
- a support bushing disposed in the through hole in an axial direction, the support bushing having a length greater than the thickness of the wall such that an amount of axial play exists between the support bushing and the wall so that the support bushing is movable in the axial direction, the support bushing includes a first collar extending radially outward from the support bushing on a first axial side of the wall and comprising a first collar end face, and a second collar extending radially outward from the support bushing on a second axial side of the wall and comprising a second collar end face;
- a lead screw nut having an end face that adjoins the first collar end face of the support bushing;
- and
- a mount that braces the second collar end face of the support bushing with an elastic element positioned between the second collar and the mount such that the lead screw nut is elastically loaded in a direction away from the wall.
A lead screw nut support arrangement that interfaces with a wall having a through hole formed therein, the support arrangement comprising:
- a support bushing disposed in the through hole in an axial direction, the support bushing having a length greater than the thickness of the wall such that an amount of axial play exists between the support bushing and the wall so that the support bushing is movable in the axial direction, the support bushing includes a first collar extending radially outward from the support bushing on a first axial side of the wall and comprising a first collar end face, and a second collar extending radially outward from the support bushing on a second axial side of the wall and comprising a second collar end face;
- a lead screw nut having an end face that adjoins the first collar end face of the support bushing;
- and
- a mount that braces the second collar end face of the support bushing with an elastic element positioned between the second collar and the mount such that the lead screw nut is elastically loaded in a direction away from the wall;
- and
- said elastic element comprising an elastomeric material, and where the elastomeric material element stresses the support bushing against the lead screw nut.
