Abstract

In a semi trailer with tiltably mounted bulk container (3), said container lies lowered with its horizontal longitudinal axis on two linear longitudinal carriers (23, 24) of the vehicle frame. The two longitudinal carriers are at a smaller distance from one another and from the carriageway at the rear than at the front. <IMAGE>

SEMI-TRAILER

The invention relates to a semitrailer, which has a horizontal, transverse to the direction of travel at the rear of the trailer located axis carries tiltably mounted silo container, which is lowered with a horizontal longitudinal axis on two longitudinal beams of the vehicle frame and has a closable outlet at the rear end.

Such a semi-trailer is below at the front A support plate is attached to the side member for the crown pin of the fifth wheel, which is inserted into the fifth wheel from above of the towing vehicle is used. The front ends of the side members must be higher for this purpose than the fifth wheel. In order to utilize the space available in the rear part of the semitrailer, in a known semi-trailer, the side members, which are arranged parallel and horizontally otherwise, at the end of the front third cranked so that the front third of the longitudinal member is higher than the rear part. Which gives a cranked support for the silo container, which is accordingly cranked.

Such crankings are extremely expensive to manufacture and also a weak point in the statics, both in the Vehicle frame as well as in the silo container.

The object of the invention is to avoid such cranks with the least possible loss of transport volume.

The invention makes use of the fact that in there is space in the front part to the side to arrange the longitudinal members there with a greater distance, which is in the rear Partly not the case because of the axle assembly, between the wheels of which there is space for the side members due to the overall height.

The double-angled setting of the side members is sufficient even with straight side members in the front area Ground clearance for the gable support and because of the front spread design enough space for; the horizontal lying on top of the cilo container, which is deeper at the front between the Side members sags than the rear. In this way, on the semitrailer, observing the specified external A non-cranked silo container can be placed horizontally at the transverse contour, which, with comparable external dimensions, is almost that has the same filling volume as the cranked silo container of the known vehicle.

The invention will now be explained in more detail with reference to the accompanying drawing.

In the drawing shows:

Figure 1 shows the semi-trailer according to the invention of

seen the side,

FIG. 2 shows the view according to arrow II from FIG. 1, Figure 3 is the right half of the view according to

Arrow III from Figure 1, and

FIGS. 4 to 6 each show the right half of the section according to arrow IV, V and VI from FIG. 1.

In the drawing, 1 denotes the vehicle frame and 2 denotes the axle assembly of a semitrailer, the one Silo 3 carries. The silo 3 consists of a circular cylindrical center piece 4, which is at both ends is closed by curved bottoms 5, 6. At the bottom at the rear end of the base 6 is a closable outlet 7 intended.

The container can withstand internal pressure and can be used to transport free-flowing, pneumatically conveyable bulk material provided. Sr is fed from above through closable openings 8 to 12 and for emptying around the horizontal, transverse to the direction of travel tilting axis 13 located on the rear linden tree of the vehicle frame 1 is tilted and emptied through the outlet 7. That Tilting bearing 14 is arranged at the rear end of the vehicle frame 1. At the front end of the vehicle frame, a hydraulic cylinder 15 is arranged, which is located on the vehicle frame and lifts the silo container at the front for tilting via a driver 16 attached to the silo container 3 and then lowered again.

In the transport position, the silo container rests with a horizontal cylinder axis 17 of its center piece 4 on a form-fittingly adapted Cross members 20, 21, 22, which are distributed over the length of the middle piece 4 and in turn on two longitudinal members 23, 24 of the vehicle frame 1 are supported. the

Longest r '.' Uyr 23, 24 extend ^f , I in a straight line over more than the entire length of the M: ttelstücks A- The mutual distance according to double arrow 25 of the longitudinal beams decreases towards the rear end and the distance to the roadway according to double arrow 26 decreases also towards the rear end. The rear ends of the side members dip into the space between the wheels 27, 28 of the axle assembly and find space there due to their smaller mutual spacing. The front parts of the side members, on the other hand, are spread further apart than the clear space according to the double arrow 29 between the wheels. The silo container 3 dips deeper between the longitudinal members in the front area than in the rear area. The rear ends of the two longitudinal members 23, 24 lie lower than the lower tangential plane 19 of the center piece 4 The two longitudinal members extend in a straight line over the entire length of the center piece 4 and mirror-symmetrically to the vertical longitudinal plane 18 of the trailer.

In the front area there is a support plate below the side members 31 for the crown pin 32 attached to the vehicle frame 1. The crown pin 32 does not engage from above shown fifth wheel of the towing articulated vehicle. Due to the inclined position of the side members, the ground clearance is according to double arrow 30 in the front area sufficient for this fifth wheel, while in the rear area the side members reach deeper.
