Description

GERMAN

According to the main patent application, there is a motor-driven carrier vehicle for agricultural use Working equipment from a horizontally adjustable frame with attached, in the track width and hydrostatically driven wheels with variable wheel spacing. The frame carries the prime mover to operate the individual wheel drives. The frame parts are due to their clamping or telescopic connection adjustable in width and length, while the control arms on the frame are not only adjustable, but are also arranged lockable. Such a carrier vehicle built according to the modular principle has the advantage of far greater lightness and maneuverability compared to the known farm tractors and adaptability to difficult terrain.

The object of the invention is the further embodiment of the carrier vehicle in that the ground pressure of the individual wheels completely or at least approximately evenly with simple movements, z. B. on slopes, on uneven ground or when changing tools, can be held.

With the greatest pulling force on a tillage machine, the soil pressure should always be the lowest possible Have value, d. That is to say, the specific contact pressure for each load-bearing member of the soil tillage implement must be used be the same, regardless of where and in what size the external forces acting on the machine are. This requirement applies not only to the machine working on the level, but also to work on slopes.

According to the invention, the object is to be achieved, the overall focus, d. H. the arrangement of Motor, transmission and wheels, relative to the chosen wheel arrangement to be able to choose absolutely freely. This free choice, however, requires a shift in the center of gravity in all three coordinates, without this any of these three directions would be particularly hindered or even impossible.

A hydrostatically driven four-wheel tractor is known, which probably has the center of gravity of the motor can be freely selected transversely to the direction of travel, but a kinematically determined one in the longitudinal direction Location to the two axes, whichever one selected wheelbase has been set. The compulsory connection chosen for this construction is required the height of the engine and the center distance is without abandoning the design principle of the known machine not to change.

It is also known in an agricultural vehicle in which the drive motor with the drive axles is combined into a unit to adjust the drive elements in the vehicle longitudinal direction. In the altitude and transverse to the longitudinal axis, no change in the center of gravity can be made.

Finally, it is known to reduce the center distance in agricultural processing vehicles To change limits, the drive motor maintaining its position relative to its longitudinal axis.

The invention eliminates the known deficiencies and provides a motorized carrier for agricultural Work tools created in which the engine on the vehicle frame regardless of the The wheel arrangement can be adjusted lengthways and / or in a manner known per se in the transverse direction and / or in height and that in a manner known per se, only one or more wheel axles are independent of the motor arrangement in the wheelbase and / or the track width are adjustable.

It is also provided that the motor is telescopic, if necessary, rests hydraulically, adjustable in length supports.

The drive motor can be connected to the liquid pump and, if necessary, distributors, regulators and conveyors be assembled into a sliding block unit.

If the carrier vehicle has to move heavy implements that work deep in the ground, the engine can open the carrier can be adjusted far forward in the direction of travel and contributes with its weight to the To keep the ground pressure of the front wheels equal to that of the rear wheels. When transitioning to lighter work and the corresponding replacement of the implement, the motor can then be moved in the longitudinal direction again of the carrier to the rear up to the point at which the front wheels Component of its weight is the rear wheel

by the excessive load on the rear wheels caused by the implement. The same Effect can also be achieved by moving the rear wheels more or less forward and adjusted back. Both adjustment options, that of the motor and that of the wheels, can also be used together get connected.

By adjusting the motor not only in the direction of travel, but also across it and in the Height, it can be achieved that ζ. B. when working across a slope, the engine remains vertical and its weight with regard to the described additional load of an attached implement on the rear wheels is evenly distributed on all wheels of the carrier vehicle.

According to the invention, it does not matter in which way the adjustability of the motor is effected. It is advantageous if the motor rests on telescopically adjustable in length supports, the The telescopic parts can also be shifted hydraulically because of the hydrostatic wheel drive a suitable source of liquid is already available. It is recommended for this purpose also, the motor with the liquid pump and possibly with distributors, regulators and / or conveyors assemble into a block.

In the drawing, the invention is shown using an exemplary embodiment.

The carrier consists of the longitudinal tubes 1 and 2 and the outer tubes 3 and 4. On the outer tube 4 sits a steering column 5 and the seat support 6 comprehensive block 7. Between the longitudinal tubes 1, 2 is the engine block 8 is suspended in brackets 10 by means of pins 9. The tabs 10 are with bolts 11 in the Lugs 12 attached to the longitudinal tubes, the lugs 12 having several bolt holes in different Have height. This enables the engine block 8 to be adjusted in height. By clamping lever 13 the tabs 12 are detachably connected to the longitudinal tubes 1 and 2. By loosening and tightening the Clamping lever 13, the engine block 8 can be adjusted over the length of the pipes 1 and 2.

The pairs of wheels 14 and 15, which are connected by the front axle 16 and the rear axle 17, are hinged by handlebars 18 on these axles and are Driven hydrostatically via lines not shown. The handlebars 18 and the axles 16 and 17 are suspended from the longitudinal tubes 1 and 2 via support parts 19 and clamps 20. The support parts 19 are with the axle plates 16 and 17 connected by bolts. The adjustment of the wheel base of the axes 16 and 17 takes place by moving the clamps 20 on the pipes 1 and 2.

The Ouerverstellung the engine block 8 takes place in that the tab pairs 10, 12 on the one Extended side of the vehicle and shortened on the other side of the vehicle. This is done with help the displacement of the bolts 11. In addition, the inclination of one pair of tabs 10, 12 must then be opposite the inclination of the other pairs of tabs 10, 12

ίο be set differently, which then the engine block ζ. B. is at a great distance from the longitudinal tube 1 and in the vicinity of the longitudinal tube 2.

The track width adjustment of the wheels 14 and 15 is carried out by increasing the distance between the Longitudinal tubes 1 and 2, which is made by moving the loosened clamps 22 on the Ouerrohren 3 and 4 is made. In addition, the support parts 19 on the axle plates 16 and 17 according to the Track width adjustment in their bolt holes 21 offset.
