Definitions
- the invention relates to a support winch, in particular for supporting trailers, with a telescopically movable in height, an outer sleeve and an inner sleeve having support member, wherein the outer sleeve comprises a mounting flange for attachment to a vehicle.
- Such support winches are used in particular for supporting trailers of a semitrailer.
- These landing gear winches are made of square tubes, which can be inserted into one another and moved against each other, as known for example from EP 1 104 369 B1.
- the invention has the object to develop landing gear with reduced weight and at the same time cheaper production costs.
- the object is achieved by a supporting winch, wherein at least one side wall of the outer sleeve and / or the inner sleeve is formed with an angled extending in the axial direction wall portion.
- the support winch is able to accommodate significantly higher bending moments.
- the angled wall portion should be angled relative to the side wall by 5 ° to 30 °, particularly preferably 15 ° to 25 °.
- the angled wall portion should not go beyond half the width of the side wall, otherwise the desired stiffening effect is less.
- an angled wall section is arranged in two opposite side walls. This ensures on the one hand for a further increased bending stiffness without additional effort in the production.
- the angled wall portion with a first portion of the mounting flange and adjacent to the opposite side wall with a second portion lie with their angled wall sections transverse to the direction of travel, that is in the direction of the vehicle longitudinal axis.
- the landing gear jolts also in the direction of the vehicle longitudinal axis, which are then collected without a material deformation of the outer and / or inner sleeve.
- the angled wall portion is directed towards the side wall in the direction of the mounting flange to the outside.
- This embodiment also leads to a higher rigidity compared to an embodiment in which the angled wall section is inclined inwards.
- the angled wall portion of the outer sleeve and the inner sleeve is arranged complementary to each other. This has the advantage that the inner sleeve rests with its entire outer circumference on the inside of the outer sleeve and is guided against rotation during the retraction or extension of the landing gear and with little play through the outer sleeve.
- the outer sleeve and the mounting flange can be made in one piece by means of roll bending of a flat steel, as well as the inner sleeve. In most cases cold forming is used, only in special cases, with large cross sections or very small bending radii, the material is heated to reduce the forces required for forming.
- the main advantage of roll-bent over extruded sleeves is the almost free choice of the alloy of the plate-like starting material. Here also common steels can be used. Furthermore, it is not necessary to disassemble individual components via a plurality of welds which are complicated to produce in production connect to. Due to the comparatively short bending process of the material, very large quantities per unit time can be produced.
- the outer sleeve and / or the inner sleeve has a maximum of one weld.
- this type of cohesive connection sleeves are formed with a self-contained hollow body, whereby the bending stiffness is further increased.
- the weld seam can be arranged at a position which is very favorable for the production, for example at the side wall lying close to the fastening flange.
- the connecting seam is arranged in the axial direction of the outer sleeve.
- the weld can run centrally through a side wall of the sleeve or in the connecting region between two mutually adjacent side walls.
- the figure shows a plan view of an outer sleeve 1 with inner sleeve 2 arranged therein of a support element 3.
- the outer sleeve 1 comprises the side walls 5a-d, which surround a substantially rectangular inner space 12.
- the side wall 5b has in its axis of symmetry a connecting weld 9, which connects both halves of the side wall 5b materially together.
- the entire landing gear is attached via the outer sleeve 1 to a vehicle, not shown.
- 5c also protruding mounting flange 4 is formed.
- the side walls 5a-d are formed from an original plate-like raw material by bending, and thus seamlessly merge.
- end portions 14a, 14b of the mounting flange 4 a distribution can be seen in each case, at which the material is bent over by 180 °.
- a sharp assignment which has been retreaded after the bending process, so that in the region of the assignment, the wall material immediately rests against each other again.
- the side walls 5a, 5c of the outer sleeve 1 are perpendicular to and the side walls 5b, 5d in the direction of travel 13.
- the opposite side walls 5a, 5c are provided with angled wall sections 7a, 7b, in the direction of the mounting flange 4 are set out by about 20 ° to the outside.
- the side walls 5a, 5c are formed with the angled wall portion 7a, 7b in order to accommodate higher forces acting on the semitrailer (not shown) during coupling in or opposite to the direction of travel 13.
- mounting holes 11 For attachment to a vehicle, not shown in mounting holes not shown mounting holes 11 are inserted.
- the fastening bolts 11 protrude beyond the flat surface of the side wall 5b with their fastening flange 4.
- the inner sleeve 2 was also formed from a plate-like starting material by roll bending and connected to a closed hollow body via the connecting weld 10.
- the connecting weld 10 is also located in the symmetry axis and is disposed immediately adjacent to the joint weld 9.
- the inner sleeve 2 is formed as a square tube with two equally long pairwise opposite side walls 6a-d, wherein the side walls 6a, 6c complementary to the side walls 5a, 5c angled wall portions 8a, 8b have.
