Description

The present invention relates to a vehicle trailer with a loading area, the vehicle trailer being designed as a high-loader.

In a vehicle trailer designed as a high-loader, the loading area is arranged on a frame and above the wheels, while the chassis is arranged under the frame. The loading area can extend over the entire width of the vehicle trailer and can be loaded from three or four sides. The drawbar is usually positioned lower than the frame. Modifying the vehicle trailer in terms of dimensions, payload, structure or functionality requires the replacement of assemblies or components or at least the relocation of individual components. In most cases, the replacement of additional assemblies or components is also necessary because the assemblies of the vehicle trailer must be adapted to one another.

If the vehicle trailer is damaged, it is often necessary to replace one or more complete assemblies. The vehicle trailer should therefore be composed of releasably attached components that can be replaced or moved without much effort. In addition, the components should have a simple shape so that the vehicle trailer can be produced inexpensively. Furthermore, it is desirable that the vehicle trailer designed as a high-loader can be coupled to a towing vehicle whose trailer coupling is arranged approximately at the height of the drawbar of the vehicle trailer, with the loading area should be aligned horizontally when coupled.

It is the object of the invention to provide a vehicle trailer designed as a high-loader, which can be modified in terms of dimensions, structure or payload and whose assemblies and components are interchangeable and have a simple shape, wherein the vehicle trailer can be coupled to such a towing vehicle with the loading surface aligned horizontally is, the trailer coupling of which is arranged at the height of the drawbar of the vehicle trailer.

This task is solved by the vehicle trailer according to claim 1.

• - the lateral end regions of the cross beams protrude and are designed as cantilever beams, and where
• - The rear end region of the drawbar frame is arranged below the front end region of the frame.

The frame is completely screwed. The individual components of the frame, namely the side members and the front and rear cross members, can be easily replaced or moved. The drawbar frame, the chassis and the body are also bolted to the frame. The vehicle trailer can be easily modified in terms of dimensions, structure, payload or functionality by replacing or moving individual components.

The vehicle trailer can be assembled according to the modular principle, whereby the shape and dimensions of the vehicle trailer can vary. Commercially available standard elements can be used for most components of the vehicle trailer. The housing part with the coupling element and the overrun brake is arranged at the same height as the drawbar frame. This means that the vehicle trailer can be coupled to such a towing vehicle with the loading area aligned horizontally, the trailer coupling of which is approximately at the height of the drawbar of the vehicle trailer.

Preferably, the front connecting element and the housing part are formed in one piece. This enables a particularly stable connection between the coupling element and the drawbar frame. The tractive force can be reliably transmitted from the coupling element via the housing part to the drawbar frame.

In addition, a parking brake can also be attached to the housing part. Other components of the brake system can be used together for both the overrun brake and the parking brake.

In addition, it can be provided that the vehicle trailer has at least one further front connecting element which is screwed to the front end region of the drawbar frame on its top side. This also contributes to the stability of the drawbar frame.

In particular, the two longitudinal beams are designed as U-profile rails, with the open sides of the two U-profile rails facing each other, so that the middle profile sections of the U-profile rails extend essentially in a vertical plane, while the legs of the U-profile rails extend extend essentially in a horizontal plane. This means that both horizontal and vertical sections of the longitudinal beam can be used to screw on adjacent components. In addition, U-profile rails are cost-effective standard elements.

The V-shaped drawbar frame can also have two U-profile rails, with the open sides of the two U-profile rails facing each other, so that the middle profile sections of the U-profile rails extend essentially in a vertical plane, while the legs of the U-profile rails Profile rails extend essentially in a horizontal plane, and preferably the U-profile rails taper from back to front in terms of their height. The horizontal and vertical sections of the drawbar frame can also be used to screw on adjacent components. The U-profile rails for the drawbar frame also contribute to a simple structure and a cost-effective vehicle trailer.

In addition, the vehicle trailer can have two central connecting elements, each of which is screwed to the inside of the drawbar frame on the one hand and to the underside of the front cross member on the other hand.

Preferably, the middle connecting elements are each three-angled and designed in a staircase shape, so that each middle connecting element has four surface sections arranged in series, with adjacent surface sections forming an angle of approximately 90 °, and with the surface sections at the two ends of the middle connecting element on the vertical inside of the The drawbar frame or the underside of the front cross member are screwed on. This shape of the middle connecting element is particularly adapted to the U-profile rail of the drawbar frame.

In one embodiment, it can be provided that the chassis has two brackets that are screwed to the undersides of the longitudinal beams, and an axle body that is attached to the brackets arranged next to one another, with a wheel being attached to each end of the axle body, and wherein a rubber suspension is preferably provided between the axle body and the holder. The vehicle trailer according to this embodiment has a single axle.

In another embodiment, it can be provided that the chassis has four brackets, two of which are screwed one behind the other to the undersides of the longitudinal beams, and two axle bodies, which are attached to two brackets arranged next to each other, with each axle body at the ends a wheel is attached, and a rubber suspension is preferably provided between the axle body and the holder. In this embodiment, the vehicle trailer therefore has a tandem axle.

An exemplary embodiment of the invention is described in more detail below with reference to the accompanying drawings.

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 frame 12, a drawbar arrangement 14, a box body 16 and a chassis 18.

The frame 12 includes two longitudinal members 20, a front cross member 22 and a rear cross member 24. 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 frame 12 is screwed. The frame 12 is preferably completely galvanized.

The two longitudinal beams 20 are designed as U-profile rails, with the open sides of the two U-profile rails facing each other. The middle profile sections of the U-profile rails extend essentially in a vertical plane, while the outer profile sections of the U-profile rails essentially extend in an upper or lower horizontal plane. The open sides of the two longitudinal beams 20 are therefore directed inwards.

The rear cross member 24 is arranged behind the two longitudinal members 20. The rear cross member 24 extends horizontally and perpendicularly to the two longitudinal members 20. The rear cross member 24 is designed as an L-profile rail, with a vertical profile section of the L-profile rail being arranged behind the rear ends of the two longitudinal members 20, while an upper horizontal profile section the L-profile rail is arranged above the rear ends of the two longitudinal beams 20.

The rear cross member 24 is screwed to the two longitudinal members 20. For this purpose, two rear angle elements 26 are provided, each with two surface sections, the surface sections being arranged at approximately a 90 ° angle to one another. The one surface sections of the rear angle elements 26 are screwed to the rear end regions of the two longitudinal beams 20 on their outer sides, while the other surface sections of the rear angle elements 26 are screwed to the front side of the vertical profile section of the rear cross beam 24.

Alternatively, the surface sections of the rear angle elements 26 can also be screwed to the rear end regions of the two longitudinal beams 20 on their insides. The lateral end regions of the rear cross member 24 protrude and are designed as cantilever beams.

The front cross member 22 is arranged in front of the two longitudinal members 20. The front cross member 22 extends horizontally and perpendicularly to the two longitudinal members 20. The lateral end regions of the front cross member 22 also protrude and are designed as cantilever beams. The front cross member 22 is at least partially designed as a U-profile rail, with the open side of the front cross member 22 directed backwards. The middle profile section of the front cross member 22 forms the front of the frame 12, while the outer profile sections of the front cross member 22 form its top and bottom.

The two longitudinal beams 20, the front cross beam 22 and the rear cross beam 24 essentially form a rectangular frame, with the lateral end regions of the front cross beam 22 and the rear cross beam 24 protruding and being designed as cantilever beams.

The drawbar arrangement 14 comprises a V-shaped drawbar frame 40, the rear end regions of which are screwed to the frame 12. The drawbar frame 40 has two U-profile rails, the open sides of which face each other. The middle profile sections of the U-profile rails of the drawbar frame 40 extend essentially in a vertical plane, while the outer profile sections of the U-profile rails of the drawbar frame 40 extend essentially in an upper and lower horizontal plane. The middle profile sections of the U-profile rails thus form the outer sides of the drawbar frame 40, while the open sides of the U-profile rails are directed inwards. In this example, the two U-profile rails of the drawbar frame 40 taper in height from back to front.

The drawbar frame 40 is screwed to the two side members 20 on the one hand and to the front cross member 22 on the other hand. For this purpose, two rear connecting elements 30 are provided, which are screwed to the outside of the longitudinal beam 20 in its front area and to the outside of the drawbar frame 40 in its rear end area. The rear connecting element 30 is designed as an elongated surface piece which is arranged vertically and the upper region of which is screwed to the outside of the longitudinal beam 20, while the lower region of which is screwed to the outside of the drawbar frame 40.

Alternatively, the two surface sections of the rear connecting element 30 can be twisted relative to one another, so that the angle of rotation between the surface sections of the rear connecting element 30 approximately corresponds to the angle between the outer sides of the longitudinal beam 20 and the drawbar frame 40. The upper surface section of the rear connecting element 30 lies flush against the outside of the longitudinal beam 20, while the lower surface section of the rear connecting element 30 lies flush against the outside of the drawbar frame 40. In this case too, the upper surface section of the rear connecting element 30 is screwed to the outside of the longitudinal beam 20 and the lower surface section of the rear connecting element 30 is screwed to the outside of the drawbar frame 40.

Furthermore, two front angle elements 28 are provided, each with two surface sections. The surface sections are arranged at approximately a 90° angle to one another. The lower vertical surface section of the front angle element 28 is screwed to the outside of the drawbar frame 40, while the upper horizontal surface section of the front angle element 28 is screwed to the underside of the front cross member 22.

In addition, two middle connecting elements 32 are provided, each of which is angled three times and is designed in the shape of a staircase. Thus, each middle connecting element 32 has four surface sections arranged in series, with adjacent surface sections forming an angle of approximately 90°. The surface section at one end of the middle connecting element 32 is screwed to the vertical inside of the drawbar frame 40, while the surface section at the other end of the middle connecting element 32 is screwed to the underside of the front cross member 22. The drawbar frame 40 is thus connected to the front cross member 22 and the two longitudinal members 20. The tensile force acting on the drawbar frame 40 is thus distributed over the front cross member 22 and the two longitudinal members 20.

In addition, two further angle elements are provided, the surface sections of which are arranged at approximately a 90 ° angle to one another and which are screwed to the front cross member 22 and the two longitudinal members 20. The two other angle elements are in 1 not visible. One surface section of the further angle element is screwed to the back of the front cross member 22, while the other surface section is screwed to the inside of the longitudinal member 20.

The front end regions of the two U-profile rails of the drawbar frame 40 are screwed together via front connecting elements 34 and 36. One or two upper front connecting elements 34 are screwed onto the tops of the front end regions of the two U-profile rails of the drawbar frame 40. A lower front connecting element 36 is screwed to the undersides of the front end regions of the two U-profile rails of the drawbar frame 40.

The tip of the V-shaped drawbar frame 40 is located at the front end region of the vehicle trailer 10. The coupling element 42 is arranged at the tip of the drawbar frame 40. The coupling element 42 is intended for coupling to a towing vehicle. In this example, the coupling element 42 is designed as a ball coupling.

The coupling element 42 is preferably designed as a safety ball coupling with a wear and safety indicator. The overrun brake 44 is arranged behind the coupling element 42. The overrun brake 44 is preferably self-adjusting and includes an automatic reversing system. The parking brake 46 is located behind the overrun brake 44. The support 48 is attached below the lower front connecting element 36.

The support wheel 50 is located on the left outside of the drawbar frame 40. The support wheel 50 is foldable and manually adjustable in height using a crank. The support 48 prevents the drawbar arrangement 14 with the brake system from resting on the ground when the support wheel 50 is retracted. The housing part 38 is arranged on and behind the lower front connecting element 36. The coupling element 42, the overrun brake 44 and the parking brake 46 are attached to the housing part 38.

Preferably, the housing part 38 and the lower front connecting element 36 are formed in one piece. This enables reliable power transmission from the coupling element 42 to the drawbar frame 40. The arrangement of the housing part 38 with the coupling element 42 between the U-profile rails of the drawbar frame 40 enables light the coupling of the vehicle trailer 10 to a towing vehicle, the trailer coupling of which is arranged approximately at the height of the drawbar arrangement 14, the loading area being aligned horizontally when coupled.
