Abstract

Carrying wagon for combined road-rail transport with dropping load floor particularly of motor vehicles whereby rolling mechanism are created as a turning bogies (4) and tow bars (5) connected by a horizontal cardan joint to a wagon bridge (1) at an application point (6) facing the center of the wagon. The bogies support the wagon bridge (1) vertically by means of side support elements (7), which run on an arc-shaped track with the center point of its curvature exactly over the application point. Advantage of the invention is that the carrying wagons with normal double gears provided to load the motor vehicles with Europe admissible length, width and height without overload permitted profile.

Description

Technical field

The invention relates to the articulated coupling of a drawbar to a carrier wagon for the combined transport of goods.

Fig. Fig. 2 is a side view of one of the ends of the wagon with a rigid, high-positioned drawbar; 3 is a side view of one of the ends of the wagon with a vertically oscillating, low-lying drawbar.

BACKGROUND OF THE INVENTION

In known carrier wagons whose normal running mechanisms are arranged in front of and behind the loading surface in a conventional manner, there are width limitations, in particular in the area of the loading surface. Therefore, in DE 42 36 161, only shorter motor vehicles can be loaded. Trailers with a permissible length of 19 m in Europe cannot be loaded. Another solution is disclosed in DE 69 500 022. Only a horizontal articulation of the travel mechanisms is described. The vertical transmission of power from the wagon to the running gear is not resolved and cannot be realized with elements used in the construction of railway vehicles such as pivot, turnstile, etc.

SUMMARY OF THE INVENTION The object of the present invention is to provide a carrier wagon which allows normal wheelsets to load motor vehicles of length, width and height which are permissible in Europe without exceeding the gauge permitted for rolling stock.

SUMMARY OF THE INVENTION

This object is solved by a carrier wagon for the combined transport of loads, preferably motor vehicles, with an lowerable loading surface, which is located in the middle of a trough-shaped wagon having both draw and impact mechanisms at both ends. swivel bogies and drawbars which are articulated and horizontally pivoted at the point of attachment, arranged in the direction of the center of the wagon, on the wagon bridge, and the bogies vertically support the wagon via side support members which move along a curved track whose center of curvature lies exactly above the drawbar attachment point.

The angle corresponding to the curvature of the track arch between the longitudinal axis of the vehicle and the longitudinal axis of the travel mechanism serves to rotate the travel mechanism by a corresponding size laterally under the wagon bridge inside the curve.

The carrying carriage according to the preferred embodiment has a drawbar rigidly connected to the bogie and, at the point of attachment, the drawbar is articulated and vertically displaceably connected to the carriage by a spherical ring which is slid on the pivot.

In a further preferred embodiment, the drawbar is vertically pivotally connected to the bogie by means of two side bearings, and at the point of attachment the drawbar is articulated and vertically displaceably connected to the wagon by a ball ring and a pin.

As a result, due to the reduced internal constraint in the area of the loading area, the necessary width for transporting the loads is advantageously achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings will illustrate the invention in more detail.

BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 1 is a top view of a wagon in a rail curve,

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1, one end is shown in the cut-out so that the chassis 4 and its articulation are visible. The wagon 1 is trough-shaped and surrounds the lowerable loading surface 2 in its central part. At the ends there are common pulling and impact mechanisms 3. The traveling mechanism is designed as a bogie 4 and is pivotably articulated with a drawbar 5 In the middle of the bogies 4, lateral support elements 7 are arranged. These support elements 7, when the bogies 4 are swiveled, move along an arcuate path with a center of curvature just above the connection point 6.

Fig. 2 shows in detail the attachment point 6. In this embodiment, the drawbar 5 is rigidly connected to the bogie 4. The vertically displaceable spherical ring 8, which is mounted at the end of the drawbar 5, bears a large vertical clearance on the pivot 9. This is mounted in the wagon bridge 1. This connection permits all emerging chassis movements.

Fig. 3 shows another embodiment in a side view of the end of the carrier car. Here, the drawbar 5 is articulated to the bogie 4 vertically pivotable via two side bearings 10. The attachment point 6 is lowered and consists of a pin 9 which is mounted in the wagon bridge 1. The vertically displaceable ball ring 8 is mounted at the end of the drawbar 5 Even with this arrangement, all movements of the bogie are possible.
