Patented in the German Empire on July 12, 1931

There are already motor vehicles known whose wheels the chassis or the car body can be approached or removed from it in the horizontal direction.

In some of these vehicles, only the rear wheels can move. With such a design, the collapsed vehicle is only with its front wheels on the ground. Obviously, this type of folding can only be used with very light vehicles, and it always requires complicated operations that could not be carried out with a heavy vehicle.
Other motor vehicles have wheels mounted on bars that allow the four wheels of the vehicle to fold together. If, however, in this case one passes from the normal position to the position of the collapsed vehicle, the rods only move in the horizontal direction, without any perpendicular displacement of the car body to the wheels, so that the wheels can be accommodated under the vehicle and at the same time the formation of the car body in the usual form is not possible.

The invention aims to eliminate these disadvantages. It consists in the wheels are also movable in the vertical direction with respect to the chassis, so that they are under the Chassis can be merged. Further features of the invention are evident the following.

Various embodiments of the invention are shown in the drawing.

Fig. 26 shows a floor plan of the vehicle according to Fig. 25 with adjustment of the individual parts on the rest position.

The motor vehicle according to Figs. 1 to 15 is composed in the following way:

The car body 1 has two seats 2 and 3 which are arranged one behind the other. The box is placed on a frame 4 (Fig. 7). The frame is preferably in the form of a single central beam which carries the important parts of the vehicle, such as the engine 5, the gear box 6 and the differential gear 7. The frame is provided with four wheels 8 _τ to 8 ₄ , which are carried by two axles 9 ^ g ₂ . Each of the axes is divided into three parts 1O ₁ , H ₁ , i2 _x and io ₂ , H ₂ , 12 _a . The middle axle part H ₁ and H ₂ remains firmly connected to the chassis. Its length is at most equal to the width of the chassis 1. The various parts 1O ₁ , H ₁ , 12 _X are connected to one another in the following way (Fig. Ii, 12):

The middle axle part H ₁ is hollow. The two lateral parts 1O ₁ , i2 _x slide into this. The attachment of each axle part 1O ₁ , M ₁ to the middle part H ₁ is done with the help of a wedge 13, which is _{inserted into a recess 14 of part 1O 1} or I ¹ Z _x and extends through openings 15, 16 of the middle axle part. On the other hand, the middle axle part H ₁ is split at 17 and provided with attachments 18 which fix the axle part 1O ₁ or Ia ₁ .

The middle axle part 62 (Figs. 14 and 15)

can also be tubular. The outer axle parts 61 and 63, which are also tubular, are inserted into the ends of the central axle part 62 during assembly. you will be held in place by this simple plugging together (Fig. 15).

Each of the axle parts 1O ₁ , IZ ₁ , io ₂ , I2 ₂ , 61, 63 is articulated _{at Ig 1} to an associated oscillating strut 2O ₁ to 2O _4. With this design, the wheels can be rotated in the direction of the arrows f _x or f ₂ to the oscillating struts. The oscillating struts 2O ₁ to 2O ₄ are in turn hinged to the chassis 4 by means of pins 2I ₁ to 2i ₄ (Figs. 16, 17) in such a way that they can rotate in the direction of the arrows f ₃ or / " _4. In addition, the oscillating struts hinged to the pin with the help of crank pin 22 _{X in} such a way that they can rotate in the direction of arrows f. or f _(i.

These various joints can be designed with pawls such as 23 _X , which are intended to prevent the oscillating struts from turning in the direction of the arrow for _> when they have been lowered.

Fig. 18 shows another embodiment that can be given to the hinges provided with ratchets. In addition, a device can be installed to hold the oscillating struts in position, as shown in Figs. 19 and 20, "in which an arcuate brake wedge 30, which is attached to a lever 31, rubs on a joint head 32 of the oscillating strut 20, go Wenn If the oscillating strut wants to rotate in the direction of arrow f _s , it is wedged tight by the brake wedge 30. The contact surfaces of the brake wedge and the joint head 32 can be smooth or serrated (see Fig. 20) Adhesion of the two surfaces to each other achieved.

The mode of operation of the device described is as follows:

During normal driving, the vehicle is set as shown in Figs. 1, 3, 5, 7 is. If you no longer need it, then you reduce your space requirements, like will now be described. .

The axle parts 1O ₁ , H ₁ , I2j are loosened by removing the wedges 13 (Figs. 11 and 12) and loosening the extensions 18. Then you swivel the oscillating struts 20 ₁ to 20 ₄ (Fig. 6, 10, 16) in the direction of the arrow / ", · around the pins iz _x . No Soon the wheels are at a height at which they swiveled under the car body Each middle axle part H ₁ remains attached to the car body (Fig. 4). The oscillating struts are held in their lowered position (Fig. 6, 4,10) by pawls 23 _X. They can then be turned around pins 2I ₁ ( This measure brings the wheels closer together. To keep them in their current position, use a sleeve or sleeve 25 _X (Fig. 13), which is placed on the axle parts 10 ₁ , i2 _x in the same way is wedged like that

middle stub axle H ₁ . When these various measures have been completed, the vehicle is very narrow. It is then easy to drive through an ordinary door and put it in a small room, e.g. B. would be sufficient for a motorcycle.

You can also bring the wheels together by using the car body in the following way (Figs. 21 to 24).

Each axis 9 is at 33 on the frame and at 34 _1; 34 ₂ hinged to the axle parts 3S _1, 35 _2, each wheel 8 _X 8. ₂ The oscillating struts 2O ₁ , 2O ₂ connect the axle parts 35 ^ 35 ₂ to the frame 36 and are _{articulated at the points 37 X} , 3S ₁ , 37 ₂ , 380 on the axle parts 35 ^ 35 ₂ and on the frame 36.

During operation (Fig. 21 to 24) the axis 9 is supported on stops 39 ^ 39 _{2 of} the frame 36 and firmly connected to this by wedges. When you lift the chassis, the vehicle is at rest. The axis 9 bends in the joint connections 33.34i »342 ^em · During this bending the wheels 8 _V 8 ₂ approach, and the joint rods 2O ₁ , 2O ₂ are at the joints yj _x , 3S ₁ , yj», 38 »( Fig. 22 to 24) also buckled.
Figs. 25, 26 show yet another embodiment of the device, which enables the distance between the wheels to be set differently from one another. In this embodiment, the axle 9 is articulated at 40 on the axle part 35 i and is _{firmly connected to the axle part 35 2} by any device 41. When the wheels are to approach, it is sufficient _{to separate the axle 9 from the axle part 35 2} by releasing the lock 41. When the wheels 8 ^ 8 ₂ approach, the axis 9 is pivoted _{against the joint rod 2O 1.}
