Description

GERMAN

The invention relates to amphibious tracked vehicles, in particular to those which, for. B. by means of a parachute can be dropped to separate infantry groups in any terrain to be transported at a relatively high speed.

The invention aims to improve amphibious tracked vehicles, their base frame two hollow box-shaped side members, one on each side of the vehicle. These well-known Crawler vehicles of the type mentioned have the disadvantage that, given the low weight to be demanded the side members are not sufficiently resistant to bending and torsion.

The invention thereby avoids the disadvantages of known vehicles of this type and exists in that each of the longitudinal beams is composed of three elements which are rigidly connected to one another are whose lowest element consists of a U-shaped iron with the opening facing downwards, while the second element forms a hermetically sealed housing lying above the U-iron, which as Float serves, and that finally the third element above the float housing partially enclosing the upper caterpillar track and at least on the side facing the vehicle a vertical one Has wall that serves to protect the occupants.

The stability properties given by the air chamber against tilting influences around the longitudinal axis in the floating state is very good because the side members are wider than any other part of the Vehicle are removed from the longitudinal axis. The rolling movements are due to the great stability small when driving under water, and due to the movements of the occupants Due weight shifts do not cause large angles of heel.

According to a development of the invention, an inner plate is on the inner leg of the U-iron and an outer plate attached to the outer leg of the U-iron, with the outer plate inward and the Inner plate is bent outwards over the bent part of the outer plate and the bent over Parts of the outer and inner panels form the floor and ceiling of a channel in which the upper Run of the caterpillar is running.

Connecting parts provided with a circular extension can be provided at the ends of the longitudinal beams be, which a tight seal of the second element forming channel between a Effect part of the U-iron and the bent part of the outer plate. Here the float can be filled in a known manner with a ball protection.

The invention is explained below with reference to the drawing, for example.

1 and 2 show, from the side and from the front, respectively, a light amphibious tracked vehicle according to the invention;

Fig. 3 illustrates the frame of this vehicle diagrammatically with the omission of parts.

According to FIGS. 1 and 2, the vehicle has a frame 1, described in more detail below, which is of a caterpillar undercarriage is carried, which among other things on each side of the frame 1 has support rollers 2, which roll on a lateral caterpillar 3, which is supported by a z. B. at the front end of the vehicle arranged sprocket 4 and driven by a then at the rear end of the Vehicle lying tension roller 5 is kept taut.

According to Fig. 3, the frame 1 of the vehicle consists essentially of two lateral hollow longitudinal members L made of thin bent sheet metal, in which the upper run of the corresponding caterpillar 3 runs, these two lateral longitudinal members supporting the parts of the chassis of the vehicle, in particular the support rollers 2 and parts 6 for cushioning the same.

In addition, the framework contains two tubular cross-members 7 and 8, which connect the opposite ends of the two longitudinal members L to one another and the motor unit 9 or we-

carry at least part of the transmission organs from the engine to the caterpillar drive.

So z. B. the motor unit 9 from the rear tubular cross member 8 and a transmission block with differential 10 from the front tubular cross member gen traverse 7 are worn.

In this way, a frame-shaped stand is obtained which, among other advantages, is simple, an excellent one Has rigidity and a completely free space between the components of the frame leaves, which contains no strut parts, so that the lounge of the vehicle immediately can be formed in the interior of the frame 1 without a car body being placed on it must become. At the lower part of the frame, all that is needed is a non-working, dense floor to be attached.

In the embodiment shown in FIG. 3, each longitudinal beam L has a U-profile 11 which extends over its entire length and the opening of which is turned downwards. This profile iron is used to hold the chassis.

An inner plate 12 and an outer plate 13 are located on the inner and outer legs of the profile iron 11 attached, with the plate 13 inwards and the plate 12 outwards over the curved part of the Plate 13 is bent so that the bent parts 13α and 12a of these outer and inner plates Form the floor or the ceiling of a channel through which the upper run of the caterpillar 3 runs.

This channel is closed laterally on the outside by a preferably removable plate 14, which z. B. is attached by screws to the plates 12 and 13 firmly connected brackets 14a.

At each end of the longitudinal beam thus formed there is a connecting piece 15 with a circular one Approach provided, which a tight seal of the channel between the transverse leg llß of the profile iron 11 and the bent part 13 a of the outer plate 13 causes so that the channel a kind Forms floating box for the longitudinal member in question, which is expediently provided with a bullet protection is filled. The floor of the lounge is formed by a metal sheet 16, which is attached to the lower Scope of the frame z. B. is attached by angle iron with the interposition of a seal 17. This sheet continues at both ends of the frame and wraps around the circular approaches of the Connectors 15 to which it is attached and thus causes the tight closure of the lounge.
