1 schematically shows an exploded perspective view of a vehicle trailer 10 according to an exemplary embodiment of the invention. The vehicle trailer 10 has a drawbar frame 12, a box body 14 and a chassis 16.

The drawbar frame 12 comprises two longitudinal beams 18 and a cross member 20. The two longitudinal beams 18 are arranged in a V-shape relative to one another, with the tip of the V-shaped drawbar frame 12 being located in the front end region of the vehicle trailer 10. The cross member 20 is arranged at the rear end of the drawbar frame 12. The terms “front” and “rear” as well as other position and direction information refer to the direction of travel of the vehicle trailer 10. The cross member 20 extends transversely to the direction of travel of the vehicle trailer 10. The lateral end regions of the cross member 20 are each connected to the rear ends of the longitudinal members 18. For example, the cross member 20 is welded or screwed to the rear ends of the longitudinal members 18. The two longitudinal beams 18 and the cross beam 20 form an equilateral triangle.

The two longitudinal beams 18 are designed as U-profile rails, with the open sides of the longitudinal beams 18 facing each other. The central profile sections of the longitudinal beams 18 thus form the lateral outer sides of the drawbar frame 12. The height of the longitudinal beam 18 is greater than its width. Preferably, the height of the longitudinal beam 18 is at least twice as large as its width. The cross member 20 is designed as a U-profile rail, the open side of which is arranged at the front. Alternatively, the cross member 20 is designed as an angle profile rail with an upper horizontal section and a lower vertical section, with the upper horizontal section extending forward.

Furthermore, the drawbar frame 12 comprises a plurality of cross struts 22. The cross struts 22 extend transversely to the direction of travel of the vehicle trailer 10 and are arranged between the two longitudinal beams 18. The ends of the cross struts 22 are preferably welded to the insides of the longitudinal beams 18. The longitudinal beams 18 and the cross struts 22 form a ladder frame in which the longitudinal beams 18 are arranged in a V-shape. In this example, the drawbar frame 12 has five cross struts 22. In addition, the drawbar frame 12 includes one or more longitudinal struts 24, which are arranged between the rearmost cross strut 22 and the cross member 20. The longitudinal struts 24 extend parallel to the direction of travel of the vehicle trailer 10. In this example, the drawbar frame 12 has two longitudinal struts 24. The longitudinal struts 24 are preferably welded to the rearmost cross strut 22 and/or the cross member 20. The cross struts 22 and longitudinal struts 24 are designed as profile rails. For example, the cross struts 22 and longitudinal struts 24 are designed as double T-profile rails or U-profile rails. The drawbar frame 12 is completely galvanized, preferably hot-dip galvanized.

The front end regions of the two longitudinal beams 18 are screwed together via an upper connecting element 26, a lower connecting element 28 and a housing part 30. The housing part 30 is arranged essentially between the front end regions of the two longitudinal beams 18. The lower connecting element 28 and the housing part 30 are preferably formed in one piece. A coupling element 32 and an overrun brake 34 are attached to the front end of the housing part 30. The coupling element 32 forms the tip of the V-shaped drawbar frame 12. The coupling element 32 is intended for coupling to a towing vehicle. In this example, the coupling element 32 is designed as a ball coupling. The coupling element 32 is preferably designed as a safety ball coupling with a wear and/or safety indicator. The overrun brake 34 is arranged behind the coupling member 32. Preferably, the overrun brake 34 is self-adjusting and/or includes an automatic reversing system.

Furthermore, a parking brake 36 is attached to the housing part 30. In this example, the parking brake 36 is arranged on the right side of the housing part 30. A support wheel 38 is screwed onto the rear end of the housing part 30. The support wheel 38 is therefore located between the two longitudinal beams 18. The support wheel 38 can be manually adjusted in height using a crank. The support wheel 38 is preferably foldable.

The chassis 16 includes four holding devices 46, two axle bodies 48 and four wheels 50. The holding device 46 has an upper horizontal section and a lower vertical section, each of which is designed as surface pieces. The upper horizontal section of the holder 46 extends inwardly from the top edge of the lower vertical section. Thus, the lower vertical section of the holding device 46 extends downward from the outer edge of the upper horizontal section. The upper horizontal section of the holding device 46 is designed as an elongated rectangular surface piece that extends parallel to the direction of travel. The lower vertical section of the holding device 46 is designed as a substantially triangular surface piece, the plane of which extends parallel to the direction of travel. In addition, the holding device 46 has a rib connected to the bottom of the upper horizontal section and the inside of the lower vertical section. The rib is designed as a surface piece whose plane extends perpendicular to the direction of travel. The rib contributes to the stability of the holding device 46.

Two holding devices 46 are arranged one behind the other in the lateral outer areas of the underside of the box structure 14. The end regions of the two axle bodies 48 are each connected to the lower vertical sections of two holding devices 46 arranged next to one another. A wheel 50 is placed at the ends of the axle bodies 48 by means of an independent wheel suspension. The chassis 16 is therefore designed as a tandem axle. Preferably there is a rubber suspension between the axle body 48 and the wheel 50 provided. The rubber suspension is maintenance-free and contributes to improving the driving behavior of the vehicle trailer 10. The hubs of the wheels 50 are preferably water-protected. The holding devices 46 and the axle bodies 48 are preferably completely galvanized.

The box body 14 includes a base plate 52, four side walls 54 and two access ramps 56. The base plate 52 is provided as a loading area. For example, the base plate 52 is designed as a screen-printed multiplex plate. Preferably, the base plate 52 is made of screen-printed wood. The screen printing wood is glued several times to make it waterproof, with the cut edges sealed. The base plate 52 has a waterproof coating. In addition, the base plate 52 has a non-slip top. The side walls 54 are preferably double-walled and made of aluminum, for example anodized aluminum. In this example, the thickness of the side wall 54 is approximately 25 mm and its height is approximately 350 mm. Furthermore, lashing eyes and/or lashing brackets can be arranged on the base plate 52. For example, the lashing eyes or lashing brackets are foldably mounted on the base plate 52.

The front side wall 54 extends over the entire width of the box body 14. The side side walls 54 extend over the entire length of the box body 14. The rear side wall 54 extends over the middle area of the rear of the box body 14. The rear side wall 54 can be folded out and preferably also removable, with the fold-out axis extending along the lower edge of the rear side wall 54.

The access ramps 56 are arranged on the two outer areas of the rear of the box body 14. The access ramps 56 can be folded out. In the folded state, the access ramps 56 extend approximately vertically upwards. When folded out, the access ramps 56 connect the rear end of the base plate 52 to the road. The access ramps 56 each have a support bracket 58. The support bracket 58 is designed as a U-shaped tubular frame. When the ramp 56 is folded in, the support bracket 58 extends approximately horizontally to the rear. When the access ramp 56 is unfolded, the support bracket 58 extends downwards so that the access ramp 56 is supported on the road. The access ramps 56 enable vehicles or mobile machines to be driven, pushed or pulled onto or from the base plate 52 in a simple manner.

The box body 14 is connected to both the drawbar frame 12 and the chassis 16. The front area of the box body 14 is screwed to the drawbar frame 12 via front angle elements 42 and rear angle elements 44. Lower vertical sections of the angle elements 42 and 44 are screwed to the outside of the longitudinal beams 18 and upper horizontal sections of the angle elements 42 and 44 are screwed to the underside of the box structure 14. The front end of the underside of the box structure 14 is screwed to the front angle elements 42. A reinforcement plate 40 is screwed on between the front angle elements 42 and the outer sides of the longitudinal beams 18. The reinforcement plate 40 is elongated and aligned parallel to the longitudinal beam 18. The reinforcing plate 40 rests on a section of the outside of the longitudinal beam 18. The reinforcement plate 40 contributes to saving material on the longitudinal beam 18. The rear area of the box structure 14 is screwed onto the cross member 20.

The chassis 16 is screwed to the underside of the box body 14. The upper horizontal sections of the holding devices 46 are screwed to the underside of the box structure 14. In the lateral outer areas of the underside of the box structure 14, two holding devices 46 are screwed one behind the other. The end regions of the two axle bodies 48 are each connected to the lower vertical sections of two holding devices 46 arranged next to one another. A wheel 50 is in turn attached to the ends of the axle bodies 48.

A fender 60 is screwed onto the side walls 54 of the box body 14. In this example, the fender 60 is formed in one piece. The fender 60 is located above the two wheels 50 arranged one behind the other. The fender 60 is preferably made of impact-resistant plastic. Furthermore, a mud flap 62 is attached to the rear end of the fender 60 and hangs downwards. The mud flap 62 is made of an elastic material.

The coupling element 32 and the overrun brake 34 are attached to the front end of the housing part 30. The coupling element 32 forms the tip of the V-shaped drawbar frame 12. The overrun brake 34 is arranged behind the coupling element 32. Furthermore, the parking brake 36 is attached to the housing part 30. The support wheel 38 is located at the rear end of the housing part 30.

The angle elements 42 and 44, which connect the box body 14 to the drawbar frame 12, are arranged under the front area of the box body 14. The chassis 16 is screwed to the underside of the box body 14. With regard to the direction of travel, the chassis 16 is arranged approximately in the middle area under the box body 14. In this example, the vehicle trailer 10 has a tandem axle, which enables a relatively high payload. In the folded state, the access ramps 56 extend approximately vertically upwards and the support bracket 58 extend approximately horizontally to the rear.
