The module 3 consists of mutually identical The 3-point truss elements 4 made of aluminum tube. All other truss elements listed in the following description have this structure. The reference numerals are therefore retained.

The side member 2 indicates at its end facing the tractor 7 an end plate 8th on, at the trailer towbar 9 is attached for coupling to the tractor.

At the other of the trailer drive 9 opposite end 10 of the longitudinal member 2 there is a 4-way cross 11 for the 3-point truss element 4 , where the connections 12 . 13 . 14 and 15 of the 4 way cross 11 are arranged perpendicular to each other in a horizontal position. The connection 12 is aligned in the direction of the longitudinal beam axis LA and with the end 10 of the truss element 4 of the longitudinal member 2 positively connected.

The connection 13 of the 4 way cross 11 Aligns with the connection 12 in the direction of the longitudinal beam axis LA. At this connection 13 is a headboard 16 for the side member 2 fixed in a form-fitting manner.

The crossbeam 17 is of cross member modules 18 from 3-point truss elements 19 formed, which have a length LQ, which is about four times compared to the length LL of the truss elements 4 is lower. The two truss elements 19 are with the connection 14 respectively. 15 of the 4 way cross 11 each positively connected. The truss elements 19 then form with the truss elements 4 of the longitudinal member a cross-shaped arrangement with the 4-way cross 11 at the crossing point KP.

At every truss element 19 of the crossbeam 17 is at its end opposite the crossing point KP end 20 a swing module 21 for a swingarm 22 positively connected.

In 2a are the swing module 21 and the module 35 for the sensor carrier shown in side view. The module 21 owns a wheel fork 23 at the front of the towbar 9 opposite end 24 a rotation axis DA for the trailing wheel 25 and another towards the back end 26 the wheel fork 23 arranged offset pivot axis SA for pivoting the wheel fork 23 having. The wheel fork 23 divides the wheel fork 23 in a follower wheel 25 associated long pivot arm SL and a short pivot arm SK, the rear end 26 the wheel fork 23 assigned.

The pivot axis SA of the wheel fork 23 is between two triangular longitudinal plates 27 respectively. 28 made of electrically insulating, the magnetic field not influencing plastic rotatably mounted. The bearing plates 27 respectively. 28 are each on the connecting sides VS of a 3-point Trussenendstücks 29 attached small width, with the longitudinal plates 27 and 28 the wheel fork 23 vertically below the lower hollow profile 5c of the 3-point truss end piece 29 engage around in the region of the pivot axis SA from the outside.

The back end 26 the wheel fork 23 is opposite the lower hollow profile 5c of the truss end piece 29 by a spring means 30 strained so that when moving the trailing wheel 25 about bumps the pivoting movement of the wheel fork 23 is damped according to the pivot axis SA accordingly.

The spring means 30 consists of a around the lower hollow section 5c of the truss end piece 29 and the end 26 the wheel fork 23 several times looped rubber rope 31 , whose ends on the hollow profile 5c are attached.

The 3-point truss piece 29 with attached longitudinal plates 27 and 28 , the wheel fork 23 with trailing wheel 25 and the spring means 30 form the vibration module 21 that with the respective end 20 of the truss element 19 for the cross member 17 is positively connected.

The module 32 for the headboard 16 consists of a 3-point truss element 33 and one on the upper hollow sections 5a and 5c of the truss element 33 attached, the magnetic field not affecting hinge joint 34 On the one hand, on the module 35 for the sensor carrier centered in alignment with the longitudinal axis LA hinged on the other hand on the upper hollow sections 5a and 5b of the truss element 33 is attached. This hinge joint 34 allows pivoting of the module 35 for the sensor carriers 36 , For example, when changing the angle of attack of the longitudinal member 2 at the trailer drive 9 or as a result of uneven terrain.

At the lower hollow profile 5c of the truss element 33 there is a stop 52 which is an angle cylinder 53 from thermoplastic material, for example, POM (polyoxymethylene) is assigned to the centrally located sensor carrier of the module 35 is attached.

The folded module 35 with its sensor carriers 36 is in 2 B shown. Through a return rope 54 , with its one end approximately perpendicular to the pivot axis SA of the trailing wheel 25 on the hollow profile 5c of the truss element 33 and with its other end in a central position on the sensor carrier 36 is struck, the angle cylinder 53 by the spring force of the return rope 54 on the stop 52 pressed and the deflected module 35 brought back to its vertical position.

The module 35 for the sensor carrier 36 consists of two spaced apart, parallel to the cross beams 17 lying cheeks 37 and 38 in which side by side at a uniform distance from each other receiving sleeves 39 are attached. The receiving sleeves 39 have opposite the terrain floor 40 a vertical position and record the sensors or probes height adjustable.

The truss elements 4 of the longitudinal member 2 , the crossbar elements of the crossbeams 19 , the truss end pieces 29 the swingarm 22 and the truss element 33 of the headboard 16 take - like that 3a to 3d show - opposite the terrain floor 40 such a situation that its third hollow profile 5c the terrain floor 40 is facing and the other two hollow sections 5a and 5b above the hollow profile 5c are arranged horizontally, so that a maximum bending and torsional rigidity of longitudinal and transverse beams 2 respectively. 17 can be achieved with respect to the pivoting movements while driving in the field.

As continues from the 1 it can be seen, are rear tension cables 41 and 42 between the towbar 9 belonging end 7 of the truss element 4 for the side member 2 and in each case the outer of the 4-way cross 11 facing away in the direction of travel FR end 43 of the truss end piece 29 the swingarm 22 intended. The respective ends of the tensioning cables 41 and 42 are located in electrically insulating plastic sleeves, which are fixed by means not shown fastening means to the corresponding truss elements. The rope tensioners 44 the ropes 41 and 42 are on the respective rope near that to the towbar 9 belonging end 7 of the truss element 4 located.

The rear tension cables 45 and 46 are on the one hand on the truss element 33 of the head part 16 and on the other hand at the end 47 of the truss end piece 29 fixed, that of the towbar 9 turned away. The attachment of the tension cables 45 and 46 corresponds to the attachment of the front tension cables 41 respectively. 42 Similarly, the cable tensioners are identical, but with the difference that they are close to the truss element 33 of the headboard 16 are located.

The bracing of side members 2 on the cross member 17 increase the torsional and bending stiffness of the trailer vehicle according to the invention 1 corresponding.

Examples of the truss elements used for the side members 2 , 4-way cross 11 , Headboard 16 , Cross member 17 and the swingarm 22 show the 3a to 3d ,

The 4 shows an example of a positive connection between two truss elements 4 , In the tubular hollow sections 5a to 5c become cone connectors 48 with cross holes 49 inserted. Through into the hollow sections 5a to 5c introduced transverse bores 50 and the cross holes 49 of the cone connector 48 a non-illustrated conical male screw is inserted, which is secured with a nut against falling out. This is the positive connection with the truss elements 4 produced.

The positive connection between the 4-way cross 11 and the truss elements 4 . 19 . 29 and 33 corresponds to the connection type shown above.

Of course, it is also possible to use, for example plug-in sockets with safety bolts instead of the cone connector.

Without departing from the invention, the positive connection can also be replaced by a non-positive connection, for example by screwing the hollow sections 5a to 5c among themselves.

The 5 and 6 show the principle of broadening the track width of the trailer according to the invention 1 , The basic structure of the trailer according to the invention 1 corresponds to the structure described in sections [0036] to [0050], in each case an expansion module 51 to the right and left module 21 for the swingarm 22 is positively attached, so that the length QL of the crossbeam 17 by the width of the expansion module 51 increased.

The expansion module 51 is made up of another 4-way cross 11 with its connections 12 . 13 . 14 and 15 , another truss end piece 29 , the longitudinal plates 27 and 28 another swingarm 22 , another truss element 33 and another sensor carrier 37 together. The connection 14 furthermore, 4-way cross 11 Aligns with the cross member axis QA and binds to the hollow sections 5a to 5c of the truss end piece 29 the module for the swingarm 22 by cone connector 48 positively. At the connection 12 further 4-way cross 11 is the other truss element 33 positively secured, that with the sensor carrier 36 over another hinge joint 34 connected is.

The expansion module 51 is still through front and rear tension cables 41a respectively. 42a and rear tension cables 45a and 46a fixed so that a multi-guyed side member 2 is present, which has sufficiently high torsional stiffness in the movement in the field. These extra tensioning cables 41a . 42a . 45a and 46a can also by means of cable tensioner 44 be tense.

The trailer vehicle according to the invention 1 can be easily removed by loosening the form-locking connections between the individual modules, but also put together again.

The dismantled modules can be easily and easily transported to the measuring field and mounted on site, so that a time-consuming approach and installation is avoided.
