Definitions

  • the invention relates to a device for the articulated arrangement of body parts, primarily the rear compartment lid, on vehicles, in particular motor vehicles, the body part being pivotally connected to the vehicle body by hinge brackets acted on by torsion bar springs.
  • a torsion bar spring acting on the rear compartment lid in the opening direction is also mounted on the body side and generally acts in a suitable manner on the hinge bracket and not directly on the rear compartment lid for actuating the rear compartment lid.
  • DE-OS 27 57 238 is mentioned, for example.
  • the object of the present invention is to reduce the parts and thus also the assembly effort in a device of the type described at the beginning.
  • the object is achieved in that the torsion bar itself serves for pivoting mounting of the body part on the vehicle body, in such a way that it also forms the vehicle-side pivot joint of the hinge bracket.
  • the torsion bar itself takes over the bearing function for the body part and thus separate bearing bolts and the like can be omitted, there is advantageously a pivotable arrangement of the body part, preferably the rear compartment lid of motor vehicles, which manages with fewer individual parts, easier and faster to assemble and, overall, also brings weight savings.
  • the torsion bar spring is mounted on both sides in receptacles of the hinge bracket and rotatably engages on both sides of the vehicle body in bearing points which can preferably be fork-shaped and arranged in respective reinforcements of the vehicle side walls.
  • the torsion bar spring is mounted in the receptacles on the one hand and for the subsequent mounting of the torsion bar spring / hinge bracket / body part assembly unit on the one hand on both sides the bearing sleeve arranged the axis of rotation forming part of the torsion bar. This advantageously ensures an exact, low-play and smooth-running mounting of the assembly unit on the vehicle body.
  • 10 denotes the roof, 11 and 12 the two so-called C-pillars, 13 the rear window and 14, 15 the two rear wheel arches.
  • At 16 one is open, i.e. without cover, shown rear space of the vehicle, in this case the trunk, numbered, in the bottom 17 of which a recess 18 is formed for the spare wheel, not shown.
  • the rear space 17 is delimited in the direction of the passenger compartment, as usual, by an almost vertical rear wall 19, which is adjoined at the top by an approximately horizontally oriented storage rear wall 20.
  • a recess 21 is recessed on the right side of the storage rear wall, which serves as a viewing opening for the assembly of the rear space cover (not shown in FIGS. 1 and 2).
  • a corresponding recess is also provided on the left in the storage rear wall 20, which, however, is not recognizable in FIG. 1 due to the perspective representation of the body.
  • the rear compartment lid In the side view according to FIG. 3, the rear compartment lid, not shown in FIGS. 1 and 2, can now be seen, once in its closed position and secondly in its opening and assembly position, and is designated by 22.
  • the opening and installation position is indicated by an apostrophe.
  • the tailgate cover as usual, has a reinforcement structure 23 on its underside.
  • the structure 23 of the rear space cover 22 is - at 24 - spot welded to a reinforcement angle profile 25, which in turn - at 26 - is connected by spot welding to a hinge bracket 27.
  • the hinge bracket 27 and thus the rear compartment lid 22 firmly connected to it can be pivoted at 28 about a horizontal axis of rotation directed transversely to the longitudinal direction of the vehicle in the direction of the arrow 29.
  • the pivoting of the rear compartment lid 22 into its open position 22 ' is carried out with the support of a torsion bar spring 30 which is bent and angled several times (cf. in particular FIGS. 4-16) and - at 31 - engages on the hinge bracket 27 on the one hand and at 32 - on the other hand supported on the underside of the storage rear wall 20 on the vehicle side.
  • the torsion bar spring 30 thus counteracts a pivoting of the rear compartment lid 22 from its open position 22 'into its closed position with a spring resistance.
  • a hinge bracket 27 is provided on both sides of the rear compartment lid 22, and the torsion bar spring 30 is - viewed in plan view - axially symmetrical (with respect to the longitudinal axis 33 of the vehicle).
  • torsion bar spring 30 serves not only as a spring for the rear compartment cover 22, but also at the same time for the pivotable mounting thereof or the hinge bracket 27 firmly connected to it.
  • FIGS. 4-10 A special embodiment of a torsion spring and bearing arrangement suitable for this is shown in FIGS. 4-10. From Fig. 4 and 7 it can be seen that the torsion bar designated here with 30a at both ends (only the left end is shown in each case) is bent twice at right angles, so that a part forming the actual axis of rotation 28 and on both sides one to each parallel, inwardly directed end piece 34 results.
  • the end piece 34 of the torsion bar spring 30a engages in the mounting position shown in FIGS. 4 and 7 in a rear receptacle 35 of the hinge bracket 27a designed as a bore. As in particular FIGS.
  • the bearing bush 36a has a longitudinal slot and is slipped onto the torsion bar spring 30a in the direction transverse to the axis of rotation 28.
  • the bearing bush 36a has an edge 37 on the outside with a diametrically continuous groove 38 into which - as a means of preventing the bearing bush 36 - the torsion bar spring 30a with its end piece bent twice, ie with the one shown in FIG 4 downward part 39 engages.
  • the bearing bush 36a is thus supported on the outside on the torsion bar spring 36a, which is bent twice at right angles.
  • the bearing bush 36a is axially secured by a spring washer 40 arranged on the torsion bar spring 36a.
  • the bearing bush 36a together with the torsion bar spring 30a passing through it, engages in a front, fork-shaped second receptacle 41 of the hinge bracket 27a.
  • the front fork-shaped receptacle 41 consists of a bearing bore 42 and a mounting slot 43, the width of which is less than the diameter of the bearing bore 42.
  • FIG. 4 shows that the torsion bar spring 30a has an overall U-shaped bend in the transverse direction to its axis of rotation 28 in its center, ie at the level of the vehicle longitudinal center axis 33.
  • the offset is designated 32 and, as already mentioned above, serves to support the torsion bar spring 30a on the vehicle side on the storage rear wall 20 of the vehicle body (see FIG. 3).
  • a second, very essential function of the bend 32 is that the torsion bar spring 30a can thereby be elastically stretched in its longitudinal direction.
  • the torsion bar spring 30a can be extended, for example by twice the amount x 1 , by elastic expansion.
  • the elastic extension on both sides by the amount x 1 serves in this case to mount the bearing bush 36a on the torsion bar spring 30a by means of the longitudinal slot 44.
  • the torsion bar spring 30a is then relieved, so that the bent spring end 34, on the one hand, and the bearing bush 36a, on the other hand, can each snap into their intended position — 35 or 42 — on the hinge bracket 27a in their assembly position.
  • FIGS. 8 to 10 Reinforcing plates 45 are attached to the rear side of the body 16 (see FIG. 1) on both sides, from which a bearing part 46 is parked.
  • the bearing part 46 forms at 47 a fork-shaped bearing point, which consists of a bearing bore 48 and an assembly slot 49, the width of which is smaller than the diameter of the bearing bore 48.
  • the larger diameter of the area 51 of the bearing bush 36a corresponds to the diameter of the bearing bore 48 at the body bearing point 47.
  • the width of the mounting slot 49 of the bearing 47 corresponds to the smaller diameter of the bearing bush area 50, so that the bearing bush - as shown in FIG. 8 - can be inserted laterally with its area 50 through the mounting slot 49 into the bearing bore 48.
  • the torsion bar spring 30a is then relaxed so that it can be shortened by the amount x 2 and thereby the bearing bush 36a with the cylindrical region 51 engages in the bearing bore 48 of the bearing point 47.
  • the bearing bush 36a not only has a conical bevel in the area 52, but it is also tapered in the shape of a truncated cone at its end 55.
  • the centering effect achieved in this way makes it easier to assemble the bearing bush 36a, torsion bar spring 30a and hinge bracket 27a.
  • FIGS. 11-17 differs from 4-10 essentially by a somewhat modified configuration of the torsion bar spring (here with 30b) and the bearing bush (here with 36b).
  • the corresponding construction elements of both embodiments are therefore provided with the same reference symbols. Deviations are identified by the index b.
  • the torsion bar spring 30b is formed such that its left end, which is bent twice at right angles (as is the not shown right-hand end of the torsion bar spring 30b), which in FIGS 56 is numbered, lies within the axis of rotation 28 of the torsion bar spring 30b.
  • the bearing bushes 36b are arranged on these mutually facing ends 56 of the torsion bar spring 30b.
  • the bearing bushes 36b themselves are not slotted and are pushed axially onto the associated associated torsion bar spring end 56.
  • the hinge bracket 27b is also configured differently in the embodiment according to FIGS. 11-17 than in the embodiment according to FIGS. 4-10. Fig.
  • the hinge bracket 27b has a closed bore 57 as a front receptacle, which cooperates with the cylindrical region 50 of smaller diameter of the bearing bush 36b (see FIGS. 11 and 14).
  • a second rear receptacle is provided on the hinge bracket 27b, which is designed as an elongated hole and is designated 58.
  • 12 and 16 make it clear that the slot width of the slot-shaped rear receptacle 58 corresponds approximately to the diameter of the torsion bar spring 30b or is somewhat larger than this torsion bar spring diameter.
  • the length of the slot-shaped receptacle 58 is dimensioned such that the end 56 of the torsion bar spring 30b bent twice at right angles can be passed axially through the receptacle 58.
  • torsion bar spring 30b is first passed with its end bent twice at right angles through the slot-shaped receptacle 58 of the hinge bracket 27b and is then stretched twice by the dimension x 1 . Then, like the bearing bush 36b, axially plugged onto the end 56 of the torsion bar spring 30b and then axially fixed by the locking washer 40.
  • the torsion bar spring 30b can now snap together with the mounted bearing bush 36b - after the torsion bar spring 30b has been relaxed beforehand - into the closed bore-shaped receptacle 57 of the hinge bracket 27b (see in particular FIG. 11). Then the assembly unit torsion bar spring 30b / bearing bush 36b / hinge bracket 27b - in accordance with the embodiment according to FIGS. 7-10 and as described in detail above - can be hooked into the side bearing 46 on the vehicle body (see FIGS. 14-17).
  • the mounting slot 49 of the bearing 46 on the vehicle body - as FIG. 3 clearly shows - is inclined slightly obliquely from top to bottom.
  • the assembly unit consisting of the rear compartment lid 22, hinge bracket 27, torsion bar spring 30 and bearing bushes 36 must therefore be installed in an assembly position corresponding to the open position of the rear compartment lid 22.
  • the direction of assembly is indicated in FIG. 3 by an arrow 59.
  • the recess 21 (see FIGS. 1 and 2) in the storage rear wall 20 of the vehicle body proves to be very helpful as a viewing opening when the aforementioned assembly unit is attached.
  • the recess 21 can be covered by cladding the storage rear wall 20 in a suitable manner after the rear compartment cover 22 or the aforementioned assembly unit has been installed.
