Abstract

A self-propelling agricultural working machine has a machine frame, a not steerable front axle and a rear axle formed as a dismountable pendulum axle connectable to the machine frame in a predetermined connecting point and provided with steerable wheels, an articulated joint releasably hingedly connectable with the machine frame for coupling the working machine with a trailer vehicle, and connecting elements for alternatingly releasably connecting the pendulum axle and the articulated joint with the machine frame in a region of the connecting point.

Claims

1. A self-propelled agricultural machine, comprising a first machine frame having a non-steerable front axle;

a steerable rear axle formed as a dismountable pendulum axle;

first releasable connecting means for pivotably connecting said rear axle to said first machine frame in a determined region of said first machine frame so that said first connecting means can be released and said rear axle can be dismounted from said first machine-frame;

a trailer vehicle having at least one further axle and a second frame;

an articulated joint releasably connectable with said first machine frame when said first connecting means is released and said rear axle is removed from said first machine frame;

said articulated joint coupling said second frame of said trailer vehicle with said first machine frame and being arranged in said region where said first connecting means connect said rear axle with said first machine frame;

second connecting means, which connect said articulated joint to said first machine frame; and

a suspension pin which hingedly connects said articulated joint with said first machine frame and extends in a longitudinal traveling direction of said first machine frame.

2. A self-propelled agricultural machine as defined in claim 1, wherein said first connecting means includes an axle pin extending in the longitudinal traveling direction of said first machine frame.

3. A self-propelled agricultural machine as defined in claim 2, wherein said first machine frame has frame members, said axle pin and said suspension pin being alternatingly mountable in said frame members of said first machine frame.

4. A self-propelling agricultural working machine as defined in claim 1, wherein said articulated joint is mountable in a front region of a said second frame of the trailer vehicle.

5. A self-propelling agricultural working machine as defined in claim 1, wherein said first machine frame has two frame members, said articulated joint being arrangeable in a region between said frame members when said pendulum rear axle is dismounted.

6. A self-propelling agricultural working machine as defined in claim 1, wherein said articulated joint has a bearing plate;

and further comprising steering cylinder-piston units having piston rods; and

connections provided for said piston rods and arranged in both outer side regions of said bearing plate.

7. A self-propelling agricultural working machine as defined in claim 6, wherein said steering cylinder-piston units are arranged between said connections on said bearing plate and rigid arms on a supporting arm of the trailer vehicle.

8. A self-propelling agricultural working machine as defined in claim 7;

and further comprising a roller bearing connecting said bearing plate with said second frame of the trailer vehicle, said roller bearing having an inner ring which is fixedly connected with said second frame and an outer ring which is fixedly connected with a lower side of said bearing plate.

9. A self-propelling agricultural working machine as defined in claim 1, wherein said articulated joint includes a bearing plate having vertical walls and receiving openings for said suspension pin, and a substantially horizontally arranged roller bearing connected with said bearing plate.
