Abstract

The invention relates to a control cylinder (70) having: a cylinder part (72) having a working space (74); first and second pistons (76, 80) relatively movably accommodated in the working space (74). ), the working space (74) is divided into a first working chamber (82), a second working chamber (84) and a third working chamber (86) arranged between the first and second working chambers (82, 84) by the piston. ), the first working chamber is impacted by the working medium via the first connecting end (88) of the control cylinder (70), and the second working chamber is impacted by the working medium via the second connecting end (91) of the control cylinder (70); At least one spring element (90) supported on the first piston (76) on the one hand and on the second piston (80) on the other hand, by means of which the pistons (76, 80) are subjected to forces in opposite directions. Impact; wherein, corresponding to the first piston (76), a first stopper (92) of the control cylinder (70) is provided, through which the first stopper limits the first piston (76) towards the second piston (80) movement; wherein, corresponding to the second piston (80), a second stopper (94) of the control cylinder (70) is provided, through which the second stopper limits the second piston (80) towards the first piston (76) )exercise.

Description

technical field

[0001] The invention relates to a control cylinder, a drive, an operating machine and a method for operating an operating machine. Background technique

[0002] Document DE 44 04 829 A1 discloses a load-controlled transmission for mobile construction machines and operating machines with at least two hydraulic motors drivable via at least one pump, the hydraulic motors being driven by the input One side of the shaft is respectively effectively connected with at least one gear pair. For the first maximum stroke of the construction machine and the operating machine, the hydraulic motors are interconnected via a clutch for summing the torques of the two hydraulic motors. The load-controlled transmission also includes a planetary transmission having at least one output shaft, the ring gear of which can be fixed via at least one brake. In this case, for a further maximum stroke of the construction machine and of the operating machine which follows this first maxi...

Embodiment Construction

[0060] figure 1 A drive 10 for a self-propelled agricultural machine is shown. The drive device 10 includes a first hydraulic motor 12 which can be driven by hydraulic oil. The hydraulic motor 12 comprises a driven shaft 14 which is rotatable about a rotational axis in a first rotational direction and in a second rotational direction opposite to the first rotational direction. The rotation of the driven shaft is indicated by directional arrow 16 . A gear wheel 18 is connected in a rotationally fixed manner to the output shaft 14 , and has a toothing 20 . The gear 18 is formed as a spur gear, for example.

[0061] The drive device 10 includes a second hydraulic motor 22 which can be driven by hydraulic oil. To drive the first hydraulic motor 12 and the second hydraulic motor 22 , the two hydraulic motors 12 and 22 are supplied with hydraulic oil via only one pump device of the drive device 10 which is common to the hydraulic motors 12 and 22 . The drive device 10 thus has ...
