ISSUED ON MARCH 21, 1931

The subject of the invention belongs to the class of suspension for motor vehicles with independently driven wheels, which by on the frame approximately parallel to the Wheel plane articulated articulated quadrangles are carried.

The essence of the invention consists in the fact that every quadrangle under the action of two longitudinal leaf springs stands on the vehicle frame with respect to the axle journal are clamped on the opposite side of the quadrangle and have lateral movements counteract the wheel.

The technical progress achieved in this way consists in the maintenance of the parallel Position of the independently movable and independently driven wheels of the motor vehicle against the influences side impacts and the weight of the waao gene. The effect of the well-known four-bar linkage the wheels are supported by those of the spring hinge quadrilaterals, which not only provide elastic support for the Bring the vehicle frame against the wheels, but also through their lateral stiffness counteract the deformations to which the links of the quadrilateral joints are exposed 'are.

In the drawing, the subject matter of the invention is for example in several embodiments illustrated.

Fig. Ι shows an embodiment in elevation of the suspension on the right rear wheel of a motor vehicle seen from the inside of the chassis, Fig. 2 the plan for this,

Fig. 3 is a section along line III-III of Fig. Ι;

Fig. 4 shows a detail of the spring fastening, Fig. 5 shows a variant of the design according to Fig. 3; Figs. 6 and 7 show different embodiments for the connection between the leaf springs, the bearing part and the chassis frame, while

Fig. 8 shows a design with springs running obliquely to the vehicle center plane illustrated.

In the embodiment according to FIGS. 1 to 3, a right rear wheel 1 driven by a cardan shaft is arranged on the steering knuckle 2 of the shaft 3. The drive is carried out by cardan shaft 4, its storage in bearings 5, 6. The bearing part 6 is suspended on pins 7, J ^a of links 8, 8 ^a. These links 8, 8 ^a , which can be straight or curved, consist, as can be seen from Fig. 2, of two rods connected by Ouerteile and are articulated to the vehicle frame at 9 and 9 °. Accordingly, the wheel is supported by a four-bar joint opposite the frame. According to the invention, the changes in shape are now recorded by three leaf springs 11, ii "and 11 * (Fig. 1), on the one hand with their more rigid end

with the frame and with her tapered End in a special way with the camp " part 6 are connected in such a way that they are longitudinally interlaced can run on this bearing part.

By an angle piece 12, the fixing of the springs to the frame, as shown in Fig. Ι seen in springs ^6, carried rigidly. But it can also, like that for them

to spring π of Fig. 1 is shown, by means of a connecting device that allows the regulation of the spring tension or the complete cancellation of the spring action. For this purpose, the thicker end of the spring is attached to a swinging bridge 13 of the frame, above which fixed stops 15 adjustable in an angle piece 12 ″ are arranged. These stops can consist, for example, of screws. If these screws are screwed down onto the bridge 13, Then this is immovable. The spring fastening then corresponds to a rigid clamping, as shown for the spring ΐΐ ^δ . If the stops are set so that there is a certain play between the bridge 13 and the stops, the end of the spring initially oscillates freely, and the spring action only occurs in one direction or the other when the bridge 13 rests against one or the other stop.

Another embodiment of the suspension is shown in Fig. 4. There is again the Spring suspended from a swinging bridge on the frame, on both sides of this suspension 21 plates 19 are arranged with the interposition of rubber plates, in the eyes of 20 threaded bolts 15 engage.

These threaded bolts pass through the web of the angle piece 17 attached to the frame and can be tightened to different degrees by wing nuts ιό, which are rotatably mounted between the horizontal leg of the piece 17 and a protruding bar ij ^a. Depending on whether the nuts 16 are tightened, the threaded bolts are more or less unscrewed

15 changed the bias of the leaf spring accordingly.

Also the rotation of the wing nut

16 by mechanical means from the car seat from being brought about.

The special fastening of the spring ι ΐ ^α on the bracket 13 according to FIG. 1 is easily detachable in that an intermediate piece 13 ″ is provided, which is fastened to ^{the bracket 13 by screw bolts 13 6.}

The support of the leaf spring with respect to the bearing part can be done in various ways take place; for example according to Fig. 1 for springs 11 and 11 * by means of handlebars 22.

The leaf spring can also be supported at the front end as in the case of the spring ii ^α , namely on a support 25 of the bearing part 6 on which the end of the spring 11 ° is supported by means of a head 27 carrying a roller 26. In the main, the spring ii ^fl serves as a reinforcement spring under heavy loads and can be removed under normal loads. Likewise, the effect may be of the springs 11 and 1 i ^a controlled by the adjustment of the stops 15 °.

In Fig. 5 a similar arrangement is illustrated when instead of cardan drive Chain transfer is applied.

In the embodiment of Fig. 6 and 7, the spring is attached to the Frame or on the bearing part 6 also for the purpose of longitudinal displacements of the spring to enable the wheel axle.

In the embodiment according to Fig. 6, the end of the spring is slidable towards the bearing parts, in that the spring head is articulated to a member 2g fastened on a rod 30 is. The rod 30 itself is slidably seated in two guides 31 of the bearing part 6.

In the embodiment according to Fig. 7, the front end of the spring 11 or ii ⁶ sits directly on a pin of the bearing part 6, while the rear ends of these springs are slidably mounted on the frame, namely on rods 30 "which can be moved in guides 31 °, where they are attached by elbows 12 ^6.

In the embodiment according to Fig. 8, the springs ir or ii ^a or ii ^{6 run} obliquely to the vehicle center plane.
