Patented in the German Empire on March 17, 1910.

On all self-propelled multi-lane vehicles, it is for the casual Compensation of turns Condition that the drive wheels with the interposition of Differential gears are coupled to the prime mover so that the different paths of the inner and outer wheel can be rolled on the floor without sliding. There such differential gear essentially one

ίο represent circumferential balance beam, so is for driving in a straight line an even load on both drive wheels, as in the generally guaranteed by the symmetrical structure of the entire vehicle - is required. A one-sided resistance immediately causes the more heavily burdened to lag behind Wheel and rolling the compensation. drove a corresponding increase in travel the less loaded bike; So there is a constant distraction of the vehicle, d. H. a Drive in in a curve. As is well known, the execution of is based on this phenomenon Turns in such vehicles by inclining the steering wheel or wheels such a one-sided resistance is consciously created.

While in motor vehicles only the wheels or the tensile load acting in the center line appear as external forces, the uniform loading of the drive wheels thus through the '. natural symmetry of the stress

is secured, come with motorized plows the back pressures occurring on the plowshares are added as such forces. These back pressures but settle due to the peculiar shape and mode of operation of the plowshares from longitudinal and transverse forces. The proposal, the mutual repeal these repercussions by symmetrical arrangement to the right and left on the throwing To achieve ploughshare to the center line of the chassis, can be in consideration of the completely changed, imperfect operation of such a plow practically not perform.

The invention follows the main idea, while maintaining uniform to one side thrown plowshares the forces acting on the rotation of the vehicle in itself completely or at least to a practically satisfactory degree by the fact that the distances the ploughshare is dimensioned asymmetrically from the center line of the vehicle, that the algebraic sum of the longitudinal forces. generated torques is the same size and acts in the opposite sense as the total torque of the transverse forces. This is achieved by deliberately moving the plowshares away from the side on which they throw up, so that those on this side Shares lying on the side on smaller, lever arms act like those on the other side, up this is done first by the longitudinal forces an excessive positive torque

ment in the opposite direction to the negative moment exerted by the transverse forces achieved; its size is then simply a matter of calculation or testing. The drawing shows an embodiment of the invention, namely shows Fig. Ι a built according to the invention Rotary plow in side view and ίο Fig. 2 the plan of the plow, while Fig. 3 is a corresponding plan of forces. The one attached to the front of the frame Motor Ii drives the transverse shaft 13 and with the interposition of a differential gear 12 through this the two drive wheels 14, one of which in one after the center the shaft 13 curved guide 15 can be adjusted in height. The operation of the engine 11 and the. With its track wreaths 16 cutting into the ground steering wheel 17 is carried out from the driver's seat 18 the linkage 19 and 20. The one at the rear Parts of the frame 10 attached ploughshares 21 are now on one side according to the invention the center line of the plow going through the center of the track. As can be seen from the force diagram, the relationships are such that the algebraic sum of the moments of the longitudinal forces s turning to the right (positive) and partly to the left (negative) is equal to the negative total torque of the transverse forces t and has the opposite effect . The following equation exists for the present example: s (a + b + c) - s (d + e + f) Externally, this arrangement occurs through the unilateral projection of the frame 10 in the Appearance. With this arrangement of the ploughshares, not only is the walk more precise and easy Guaranteed plow, but also its steering ability significantly improved, since the sensing -45 wreath 16 of the steering wheel 17 is practically no longer burdened by lateral pressures and when driving in a straight line also exactly in the direction of travel, instead of like anything else can stand askew. The device shown is further developed in the sense that the ground resistance of the steering wheel also results in a positive torque with the aid of the lever arm χ corresponding to its one-sided attachment. As a result, the displacement of the ploughshare 21 is still limited as far as possible, while on the other hand the steering wheel arrives at a location which is particularly favorable for its mode of operation, in that it comes into effect when steering with the greatest possible lever arm. Pa τ ε ν τ- claim: Motor plow with interposition of a differential gear between engine and Driving wheels and with plow bodies that rise up on one side and are rigidly connected to the motor frame, characterized in that, that the distances of the plow body from the center line of the vehicle under bridging from the side facing the plow body raise, are dimensioned asymmetrically in such a way that the algebraic sum of the positive and negative longitudinal forces acting on the plow bodies Torques is the same and acts in the opposite sense as the negative total torque with the transverse forces, for . Purposes to ensure an even load on the drive wheels. In addition 1 blue drawings.
