Definitions

  • the invention relates to a suspension of a pivot part on a frame or the like, in particular a hood of a motor vehicle, which can be pivoted freely in one direction at one end and is movably supported at the other end on a bearing until it rests in a guide of a stop.
  • a mounting for a tailgate of a vehicle known from DE-C-3 344 592 contains on each side a hinge bracket attached to the body and a hinge lever connected to the tailgate, in which two scenes are incorporated in the form of longitudinal slots.
  • the scenes overlap bolts held in the hinge bracket and run to one another in such a way that there is no pure circular movement around one of the bolts when the tailgate is moved.
  • the storage is disadvantageous insofar as the tailgate cannot be removed even if the other bolt has left the setting assigned to it. Rather, removal of the tailgate is only possible after removing the bolt that penetrates the closed link.
  • the hinge lever and the hinge bracket must be kept small. Accordingly, the hinge lever must be guided laterally in the area of its scenes intended for guidance and reinforced in places.
  • this storage is very tied to the use of a flat tailgate that extends essentially in one plane and is relatively stiff in this. If this storage is to be used in a spatial hood, the hood section projecting beyond the hinge brackets will exert a high bending moment, which requires a further material reinforcement of the components of the storage.
  • the object on which the invention is based is seen in improving the suspension in such a way that the pivoting part can be removed more easily and more quickly and the scenes are kept free from excessive load due to the weight and bending moments.
  • the swivel part can be disassembled without loosening bolts, ie removed from the bearing as soon as the stop is no longer effective; a bolt or the like cannot be removed because the guideways are open at one end.
  • the two in the suspension area End regions of the swivel part located are held at one end - above - and at the other end - below - by means of the bearing and the guide, so that no bending moments emanate from a spatially designed swivel part that would only have to be taken over by the bearing or only the guide.
  • the weight of the hood is borne by both the bearing and the guide when the pivoting part is not pivoted; in contrast to the known storage, the entire load is not introduced into a single part.
  • the guide part and the tab are provided on a bracket that can be prefabricated and then attached to the swivel part.
  • This bracket can also be designed so that it can be attached to covers of different sizes.
  • a bracket that is used for example, in a bonnet
  • a flat frame can also be used, which is attached to another cover by welding or screwing.
  • a suspension 10 of a swivel part 12 has a bearing 14 and a stop 16.
  • a support member 18 is also provided. In a side view of the drawing, one would recognize that the suspension 10 and the swivel part 12 are formed symmetrically to a longitudinal center plane.
  • the swivel part 12 which in this exemplary embodiment is formed by a hood of an agricultural tractor, has a U-shaped cross section in the viewing direction and is closed at one end, namely at the front end and on the right in the drawing.
  • a tab 20 with a bore 22 is attached on its inside, into which a retaining bolt, not shown, can be inserted for fastening one end of the support member 18.
  • a bracket 24 is welded onto its underside, which serves on the one hand to stiffen the swivel part 12 and on the other hand accommodates parts of the bearing 14 and the stop 16, as will be described later.
  • closure elements can be provided on the front of the swivel part 12, which hold the swivel part 12 in its lower end position.
  • the bearing 14 is composed of a transverse axis 26 and a tab 28, the tab 28 on the bracket 24 and the transverse axis 26 are attached to a frame, not shown, which carries the pivot part 12 as a whole, and wherein the transverse axis 26 is parallel to the The pivot axis of the pivot part 12 runs.
  • the tab 28 is fork-shaped with two legs 30, which leave sufficient space between them for receiving the transverse axis 26.
  • the space created by the legs 30 is somewhat deeper than the diameter of the transverse axis 26, ie they protrude beyond the transverse axis 26.
  • the tabs 28 are arranged with respect to the rear end of the pivot member 12 that they are a certain distance from it, for. B. about 10 cm.
  • the transverse axis 26 is a simple round steel bar which, in this exemplary embodiment, is arranged horizontally and transversely to the direction of travel of the vehicle carrying the swivel part 12, that is to say the bonnet.
  • the stop 16 is formed from a guide 32 and a guide part 34 guided therein. Of these, the guide part 34 is in turn attached to the bracket 24 and the guide 32 to the frame.
  • the guide 32 contains a guide track 38 which is worked into a plate 36 and which initially runs horizontally and then rises slightly.
  • the course of the guide track 38 corresponds essentially to a section of a circle around the transverse axis 26 and thus around the bearing 14.
  • a guide 32 is provided on each side of the swivel part 12.
  • the guide part 34 has the shape of a bolt with a shaft part 40 and a collar 42, the diameter of the shaft part 40 being slightly smaller than the width of the guide track 38 and the guide part 34 being able to slide in the guide track 38.
  • the collar 42 ensures that the pivoting part experiences a lateral hold.
  • the length of the guide track 38 is dimensioned such that the shaft part 40 leaves the guide track 38 when the cover has been raised by approximately 30 °.
  • the support member 18 extends from a bearing point 44 on the frame on the one hand to the tab 20 provided on the underside of the pivoting part 12 and takes its shortest length in the case of a gas pressure spring in the it also has the greatest preload, either shortly before reaching its lower end position or in this one. If the gas pressure spring designed as a support member 18 already reaches its shortest length before the lower end position of the swivel part 12 and if it extends again to this end position, a dead center position occurs in which it is ineffective. After overcoming this dead center position, the support member 18 strives to lengthen again, with the result that it pulls the pivoting part 12 downward.
  • the support member 18 can of course also be designed as a simple support rod instead of a gas pressure accumulator, but then the advantageous effects are eliminated by the use of the gas pressure spring.
  • a strut can be provided between the bearing point 44 and the transverse axis 26, which absorbs the forces generated by the use of the gas pressure spring.
  • pivot part 12 is in its lower end position, as shown in solid lines in the drawing, and that a gas pressure spring is used as the support member 18.
  • the swivel part 12 is gripped and raised at its front end region, if necessary after the closure elements have been opened. If the swivel part 12 has been raised so far that the support member 18 has overcome its dead center position, then the gas pressure spring extends and swivels the swivel part 12 upwards. While the swivel part 12 swivels upwards, the shaft part 40 of the guide part 34 moves in the Guideway 38 until it has reached its open end.
  • the tab 28 of the bearing 14 stands out slightly from the transverse axis 26, but prevents the pivoting part 12 from being pulled forward by the gas pressure spring, ie to the right in the drawing. If the swivel part 12 has now reached its upper end position, which is completely sufficient for normal maintenance work, then it stops because the gas pressure spring has reached its maximum length.
  • the retaining bolt connecting the support member 18 (gas pressure accumulator) to the swivel part 12 can be removed from the tab 20.
  • the swivel part 12 can then be swiveled further upwards, the shaft part 40 emerging from the guide track 38, so that the swivel part 12 can then be removed upwards.
  • the pivot part 12 is then completely detached from the frame when the tab 28 no longer overlaps the transverse axis 26. In order to put the swivel part 12 back on the frame, it is only necessary to proceed in the reverse order.
  • the rear edge of the pivot part 12 performs a movement on a circular arc during the pivoting process, due to which the pivot part 12 may have a structure adjacent to it, such as about a cabin, moved away.
