Definitions

  • the invention relates to a chassis for
  • Such a chassis is known from DE-U-91 03 811.
  • the chassis has a V-shaped rigid
  • Drawbar a trailer hitch, at least one axle and a body.
  • the drawbar is designed uniformly for different payloads within a trailer series, the longitudinal members having at least the same shape and length.
  • Adjustment grids for the body are available to adapt the chassis to the different payload requirements. There may also be an adjustment grid for changes in the position of the axle bracket.
  • the invention solves this problem with the features in the main claim.
  • the effective drawbar length depends on the permissible total weight of the trailer and changes with it. It is measured according to the formula given.
  • This effective drawbar length which is preferably a minimum dimension, offers optimized driving properties of the chassis. The roll and roll tendency, damping and handling are improved.
  • An adjustment grid can be provided for variable attachment of the body to the chassis.
  • one or more additional adjustment grids can be present on the side members. They can be used for various purposes, e.g. attaching supports, rear extensions, etc.
  • the stile position can remain the same, as can the axis system.
  • the axle dimensions can be uniform, especially with regard to the system, support and wheel connections.
  • the chassis can also be a lightweight construction with optimized use of materials.
  • Figure 1 to 4 different varieties of chassis in side view and top view.
  • FIGS 1 and 2 show a chassis (1) for a single-axle trailer in a side view
  • the chassis has a V-shaped rigid drawbar (2) and two side members (6). These components can each consist of one or more parts, e.g. Drawbar spars (7) and longitudinal spars (8).
  • the drawbar (2) can also be formed by the side members (6).
  • One or more cross members (17) can additionally be installed between the longitudinal members (6).
  • the chassis (1) has a single axle with an axle bracket (16) clamped between the side members (6) and a semi-trailing arm or trailing link axle with wheel axles (3). It is preferably a semi-trailing arm with a wide track.
  • the chassis (1) also has a brake system (15) which, for example, consists of an overrun brake system which is connected to the wheel brakes via a pull rod or a cable pull.
  • the drawbar (2) carries a trailer hitch (5) of any suitable type on the head. In the preferred embodiment, it is a ball-head trailer coupling, which can also be equipped with a friction brake to dampen the rolling movements.
  • the effective drawbar length (L) measures from the effective coupling point of the trailer coupling (5) to a wheel axle reference point (4), which lies on the line of the wheel axle (3) in the single-axle trailer shown.
  • the effective drawbar length (L) represents the clear distance between these points, as shown in Figure 2.
  • the coupling reference point is, for example, the center of the dome for the coupling ball.
  • the effective drawbar length (L) is from the permissible
  • Total weight of the trailer depends on and varies with this. It is equal to or greater than the result value of the following formula:
  • the permissible total weight is used as an exponent for the factor 1,0004.
  • the exponential value obtained is multiplied by the second factor 2.3.
  • the value for the permissible total weight of the trailer is entered in kilograms, from which the effective drawbar length (L) is calculated in meters.
  • the formula results with the following refined factors: 2.34212 * 1,00042 perm.total weight.
  • Drawbar lengths (L) can be adjusted by variable axle fastenings or by adjusting the length of the side members (6), in particular the longitudinal spars (8) can be achieved.
  • FIG. 3 shows a variant of the single-axle trailer from FIG. 1 with an essentially V-shaped chassis (1), in which the longitudinal bars (8) are also spread out in a V-shape.
  • the side members (6) were parallel.
  • Figure 4 shows a trailer variant with a tandem axle.
  • the two wheel axles (3) are spaced apart from each other in the longitudinal direction of the trailer.
  • the relevant wheel axis reference point (4) for the tandem axis shown lies on the center line between the two wheel axes (3).
  • the effective drawbar length (L) is thus measured up to this wheel axis reference point (4) between the wheel axes (3).
  • the chassis (1) can have one or more adjustment grids (12, 13, 14) for the variable attachment of different parts.
  • the adjustment grids (12, 13, 14) are present on both side members (6) and are center-symmetrical to each other.
  • the adjustment grids (12, 13, 14) can be designed in any suitable manner and consist e.g. consisting of several holes that are aligned one behind the other in a row or in a parallel double row in the longitudinal direction of the beam. Instead of holes, attachment points, nipples or the like can also be used for other fastening options.
  • the front adjustment grid (12) is used, for example, to fasten fittings for a body (9) of the trailer.
  • the fitting parts can be, for example, angled flange plates which are fastened on one or both sides to the web of the longitudinal members (6) and which provide a fastening and support surface for the structure (9) on the upper side.
  • the structure (9) can be compared via the adjustment grid (12) the wheel axle (3) can be moved back and forth, which enables, for example, weight compensation.
  • the first adjustment grid (12) is located, for example, on the drawbar bars (7).
  • the next adjustment grid (13) can be arranged on the longitudinal spars (8) and serves e.g. the length-adjustable fastening of trailer supports (10).
  • an adjustment grid (14) can also be arranged, which is provided for the assembly of a rear extension (11), with which the side members (6) can be extended a little to the rear if necessary and to adapt to variable body lengths.
  • further trailer supports (10) can also be adjustably attached to this or a further adjustment grid (14).
  • chassis (1) can in principle have any shape and be made in one or more parts.
  • the wheel axles can be of any design.
  • the axle supports (16) can be, for example, rubber spring axles or any other system.
  • the brake system, the bodies and the other chassis parts are also variable.
  • the longitudinal beams (6) can have a flexible length and cross-sectional profile and weight-saving recesses.

Abstract

La présente invention concerne un châssis (1) de remorque automobile présentant un timon d'attelage (2) fixe en forme de V, un dispositif d'attelage de remorque (5), au moins un axe (3) et une structure. La longueur (L) la plus efficace du timon d'attelage depuis le dispositif d'attelage (5) jusqu'à un point de référence de l'axe de roues (4) est dimensionnée en fonction du poids total admissible [kg] de la remorque. Elle est égale ou supérieure à (2,3*1,0004 poids total admissible) [m].
