Description

GERMAN

The invention relates to an agricultural tractor and self-propelled work machine, which by changing the frame and chassis parts as a tractor and agricultural machine or as an implement carrier, can be used preferably for harvesters.

Agricultural machines are already known under the designation equipment carrier in which the rear and front axles are connected by one or more longitudinal members arranged parallel to the longitudinal center line of the vehicle and used to hold transport and working equipment to be attached. These devices support fulfill the purpose of a working machine in connection with small attachments completely, but at spatially environmentally ^X 5 sive machines, such as combines, the driver's view is obstructed and the continuous flow of the crop material disturbed by the drive axle. Due to the one-sided shift of the center of gravity to the drive axis, the device carriers are only partially suitable as a tractor.

There are also known tractors in which the front and rear axles are extended on one side the tractors can be widened laterally in order to be able to accommodate larger attachments in particular. For widening, special axles are built in or extended axle halves are attached provided flanges attached. The long shaft halves are very sensitive to bending, so that Damage to the chassis can occur when driving over uneven floors. The low flexural strength this long shaft halves also has the disadvantage that there are no fixed ones for the machines to be attached Conditions are in place so that the frames of these machines are made correspondingly stable have to.

The invention overcomes these disadvantages by placing the wheels on one side of their original seat removed and by a mounting frame, which is connected by using two with a longitudinal strut Ouerstraben H-shaped and provided with connection points for a second longitudinal stiffener connected to the machine.

To make it easier to pick up heavy machines, there are known per se on the installation frame marked with * ■ * Supports provided with rollers and pivotably mounted, preferably hydraulically operated hoists attached.

The engine block is with its central axis opposite to the central axis of the transmission block to the side fixed side of the undercarriage, so that the engine The space required is shifted to the outside beyond the width of the transmission.

game depicting drawing explained in more detail. It shows

Fig. 1 shows a tractor according to the invention without the installation frame as a tractor in three views, Fig. 2 the installation frame and

Fig. 3 the tractor with built-in frame as a working machine in two views.

The engine block 1 is screwed laterally offset to the transmission block 2. The left front wheel 3 and the left rear wheel 4 are detachably flanged to the front axle pivot bearing 5 or to the transmission block. The rear wheel bearing is designed as a portal axle, with the portal axle 6 on both sides in the cavity of the Wheel rim is housed.

The mounting frame 7 is provided on the end faces of the cross struts with flanges 8, which the The flanges on the front and rear axles. There are more on the inside of the cross braces Flanges 9 are provided for installing a second longitudinal stiffener.

With roller pads 10 are attached to the cross braces to accommodate larger To facilitate machines. Pivoting supports 11 and serve to fasten the machine swiveling hoists 12.

The rear cross bar also serves to accommodate an extension drive shaft.

For use as a tractor, the tractor is used without an installation frame 7. He then resembles a normal tractor. If agricultural machines are to be attached, the installation frame between the transmission block 2, the front axle pivot bearing 5 and the rear or front wheel built-in.

Through the outwardly offset engine block 1 and those housed within the wheel rim cavity Portal axles of the rear wheels create a completely free space for the saddle-up of larger machines.

The add-on machines are pushed onto the insert frame via the supports 10 provided with rollers and attached to the pivotable supports 11. The hoists 12 lift the add-on machine in working position.
