Description

The The invention relates to a semi-trailer with one on wheels stored ground floor area section and one opposite the saddle bearing portion raisedly disposed on the base bottom surface portion for mounting on a semitrailer tractor and with two folding wheels Ramps.

semitrailer with a hinged or telescopically retractable ramp known enough.

For example, the DE 78 21 681 U1 a car transporter structure for trucks with an upper and lower loading platform, which are parallelogram connected by four scissor joints.

Also DE 10 2004 056 825 A1 discloses an auto transporter with telescopically extendable ramp at the rear of the vehicle and an auto transport trailer.

Furthermore, from the DE 44 14 528 A1 discloses a system for loading and unloading of railway cars. In order to enable a fast loading and unloading, the loading area of the railway cars of a train is designed as a roller conveyor. At each charging station of the railway, a loading roller conveyor is provided on the track. In the case of wagons driven on loading roller conveyors, a continuous roller conveyor of loading roller track and the roller conveyor of the wagon is thus formed.

Furthermore, it is off WO 02/23149 A1 a semitrailer equipped as a vehicle testing station, which also has a ramp on its rear side. However, the two-piece ramp is quite steep to reach an intermediate floor. With lowered cars or cars with spoilers, the semi-trailer can not be used.

outgoing It is an object of the present invention to provide an improved Semi-trailer to provide that allows fast loading and unloading and in particular as a test vehicle for motor vehicles can be used.

The Task is with the semi-trailer of the type mentioned solved by having a rear ramp at the rear of the semitrailer and a front ramp at the front of the fifth wheel support section is arranged and that above the bottom surface portion one in the saddle bearing section passing, sublime the main bottom surface portion arranged main bottom surface is.

Of the Semitrailer is thus through the above the bottom surface portion arranged main floor surface to the plane of the saddle bearing section adapted so that a loading on the ramp from Stern on the raised main floor area and from there on a discharge over the front over the plane the saddle bearing section is enabled or vice versa. Thus, a use of the semi-trailer according to the roll-on roll-off principle respectively. For example, in the semitrailer technically vehicles to be checked from the rear to the semi-trailer Retract to the main floor area and after passing through a Test track on the front over the to the saddle bearing section drive out adjacent ramp again from the semi-trailer, without that the direction needs to be changed.

The Providing as long a ramp as possible in a preferred embodiment by tripartite the Ramp into a first, hinged to the main floor area Ramp section, one to the first ramp section at the Anlenkkante end region opposite the main bottom surface hinged second ramp section and one to the second ramp section at the Anlenkkante opposite to the ramp section End area hinged third ramp section.

A Such three-piece ramp is over the conventional two-part ramps much longer and thus allows a flatter approach angle to the raised main floor area. This extended ramp can also be folded over by the tripartite division be without an excessive height exhibit.

In one embodiment is with closing the ramp the first ramp section can be folded down into a vertical position, the second ramp section can be folded up into a vertical position and the third ramp section can be folded down into a vertical position. In this embodiment, the height difference becomes between the bottom floor section and the main floor surface exploited to the hinged to the main floor surface take first ramp section and the deflection point for the second ramp section from the plane of the main floor surface down into the plane of the bottom surface portion and, if necessary, to relocate below it. With it increased itself for receiving the folded-up second ramp section available height. The third ramp section can then starting from the upper articulation edge of the second ramp section to be folded down again and thus the same Have length, as the second ramp section.

In another preferred embodiment In order to close the ramp, the third ramp section can be folded over onto the second ramp section, the second ramp section can be folded down into a vertical position and the first ramp section can be folded up into a vertical position. The three ramp sections may then be approximately the same length in this embodiment. In order to accommodate the third ramp section on the movable surface of the second Rampenab section and to allow folding of the second ramp section, however, the third ramp section should be slightly shorter than the second ramp section.

In In another embodiment, the front and / or rear ramp at least three telescopically into or over each other have slidable ramp sections.

Especially Advantageously, the semi-trailer is set up for use as a motor vehicle inspection device, in the motor vehicle testing equipment in the main floor area, such as a brake testing system, a tire tread measuring unit, a jib device etc. is integrated.

However, since the test space is cramped in a semitrailer, preferably displaceable side wall sections are provided with integrated roof sections, which can be moved out laterally beyond the basic width of the semitrailer and provide at least one space adjoining the main floor surface, as this basically, for example WO 02/23149 A1 is known.

Especially also advantageous is a height-displaceable mounted Roof element provided, which covers the bottom floor surface portion, the saddle bearing support section and the main floor surface surrounding sidewalls over their height partially included. For a transport of the semitrailer can the roof element is thus displaced downwards telescopically, wherein the roof element encloses the side walls. In this way, the effective height of the semi-trailer reduced to the permitted height. When using For example, as a motor vehicle inspection station is stationary Operation of the semi-trailer then the roof element again telescopic drove up, leaving a sufficient working height in particular for the use of the car lifting device is ready.

Of the through the raised to the bottom surface portion arranged Main floor created raised floor can be beneficial for accommodating auxiliary and ancillary components as well as an underfloor capable Lift are used.

By the hydraulically operated lifting roof and the hydraulic extendable operator cabs is the passage of test vehicles with simultaneous all-round inspection by the vehicle inspector possible. The order of upgrading and disarming is lowered by the over the approached operator cabins lowering Lifting roof determined.

1 leaves a semi-trailer 1 with a mobile ladder frame 2 recognize the one on wheels 3 stored ground floor area section 4 Has. For bearing on a tractor unit, not shown, at the front area of the semitrailer there is a fifth wheel support section 5 provided, the upper side raised to the bottom surface portion 4 is. Above the ground floor area section 4 is a raised to the ground floor surface section 4 arranged main floor area 6 intended. The space between ground floor area section 4 and main floor area 6 is used to hold auxiliary and auxiliary equipment 7 as well as an underfloor-capable trolley lifting device 8th (Lift) used.

The ladder frame 2 is upwards of side walls 9 and upwards by a hydraulically height-displaceable mounted roof element 10 completed. In the lowered state, the roof element covers 10 the side walls 9 partly over their height. By the hydraulic process of the roof element 10 upwards, enough space is created to be on the carriage lift 8th to drive up the vehicle, as in 2 is shown.

At the front adjacent to the saddle bearing section 5 and adjacent to the stern the back end of the ladder frame 2 is each a three-piece ramp 11a . 11b arranged, which can be operated by means of hydraulic cylinder by remote control. By the tripartite division of the ramp 11a . 11b is a closure of the front sides of the semi-trailer 1 possible and at the same time is a sufficient length of the ramp 11a . 11b ensured with a low contact angle of a maximum of 10 ° and preferably about 6 ° to 8 °, the driving on the semi-trailer 1 also allowed with lowered motor vehicles or motor vehicles with spoilers.

The ramps 11a . 11b each have a first, to the main floor area 4 articulated ramp section 12a , on to the first ramp section 12a at the articulation edge on the main floor surface 4 opposite end portion hinged second ramp section 12b and one to the second ramp section 12b at which the Anlenkkante to the first ramp section 12a opposite end portion hinged third ramp section 12c ,

The third ramp section 12c is articulated to the second ramp section 12b stored and is in the area of the joint storage by a hinged support 13a supported. Likewise, the second ramp section 12b by means of joints on the first ramp section 12a stored and is also in the area of the joints with a support 13b supported.

2 lets the semi-trailer 1 out 1 detect. It is clear that the jacks 8th in the form of a lift from the raised floor between ground floor surface section 4 and main floor area 8th is herausfahrbar to a vehicle to be tested 14 to move up.

3 leaves a top view of the semi-trailer 1 out 1 and 2 detect. This is the three-part design of the ramps 11a . 11b more clear. It is also recognizable that the outer third ramp sections 12c are unfoldable by hand while folding the second ramp section 12b on the first ramp section 12a done by means of hydraulic cylinders.

Sketched is also the car lift 8th as well as an adjoining Bremen test bench 16 which is in the main floor area 6 is integrated.

To provide sufficient test space, sidewall sections are 9a . 9b . 9c . 9d . 9e hydraulically extendable to operator cabs and movement space laterally adjacent to the lane for the vehicle to be examined 14 to create from at least one to the main floor area 6 to provide adjoining space.

In the interior of the semitrailer 1 and possibly also to the outside are preferably arranged distributed cameras installed over a data network with an image projection surface such. B. are connected to a monitor to record the progress of a vehicle inspection with the cameras and to document the respective test steps and transparent on the image projection surface for the vehicle owner.

4 leaves a cross-sectional view through the semi-trailer 1 out 1 to 3 detect. It becomes clear that by shifting the side wall sections 9a . 9d is created to the outside lateral free space. It is also recognizable that the roof element 10 is moved up and still the side walls 9 includes at its upper ends. It can also be seen that the retractable operator cabins have integrated roof sections 17 as well as hydraulically with the side wall sections 9b . 9d outwardly extendable floor elements 18 to have.

The mounting of the withdrawable operator cabins 19a . 19b on the outer edge via telescopic extendable hydraulic cylinder 20 ,

5a to 5d let the sequence of movement when folding the three-piece ramps 11 using the example of the rear ramp 11b detect. First, the third ramp section 12d on the middle, second ramp section 12b folded and the rear support 13a pivoted back. Then with the telescopic cylinders 15 the middle second ramp section 12b folded up and that in the region of the articulation of the second ramp section 12b to the first ramp section 12a located supports 13b folded away. Then, as in the 5b it can be seen, the second ramp section 12b with the third ramp section lying thereon 12c forward to the first ramp section 12a worked. Subsequently, the thus folded package of ramp sections 12a to 12c folded up to close the front of the semi-trailer, as in the 5c and 5d outlined. In the folded state is the first ramp section 12a with its free end turned up, the second ramp section 12b with its free, to the third ramp section 12c subsequent end folded down and the third ramp section 12c again with its end pointing upwards worked.

Due to the fact that the manually foldable third ramp section 12c between the over the hydraulic cylinders 15 held together first and second ramp section 12a and 12b works, it ensures that the folded package of ramp sections 12a to 12c stable and shakeproof is stored.

6 leaves a detail view of the hydraulic cylinder 15 for the first and second ramp sections 12a . 12b recognize related kinematics. The hydraulic cylinder 15 is the side of the first ramp section at (small) distance to the articulation edge to the second ramp section 12b arranged pivotally. The telescopic pole 21 is at a kink to one with a free end in the region of the Anlenkkante to the first ramp section 12a hinged L-shaped lever 22 hinged. The free end starting from the bend carries a joint for the pivotable mounting of a connecting rod 23 whose free end is at a storage point 24 to the second ramp section 12b is articulated. In this way, a kinematics is created, the low expansion in the extension direction of the ramp sections 12a . 12b the required leverage applies. The small footprint is important to accommodate the kinematics in a storage space with folded ramp.
