Abstract: A swivel angle measuring device is configured to indirectly sense a swivel angle of a swashplate or cylinder drum of an axial piston machine. The swivel angle is adjustable using an adjustment piston guided in an adjustment cylinder. The swivel angle measuring device includes a movable encoder and a transducer affixed to a housing. The encoder is formed by two permanent magnets that are carried linearly and translationally by the adjustment piston along its direction of movement and that have a distance to one other.

Abstract: A field sprayer, with a longitudinal axis oriented in a direction of travel, includes a rod assembly extending substantially transversely in relation to the longitudinal axis, and an actuator. An acceleration sensor attached to the rod assembly is configured to determine undesired tilt movement of the rod assembly, and the actuator enables the rod assembly to swivel about a swivel axis in order to compensate for the undesired tilt movement. The field sprayer further includes a control unit configured to operate the actuator so as to produce a counter tilt in order to compensate for disturbance variables affecting a tilt of the rod assembly which act on the rod assembly other than via a frame of the field sprayer. The control unit is further configured to operate the actuator during, and preferably at the start of an undesired tilt movement.

Abstract: The invention relates to a drive system and to a method for monitoring a hydrostatic drive (1). The hydrostatic drive (1) has at least one hydrostatic piston engine (2) on which a control unit (6, 6?), which controls the hydrostatic piston engine (2, 2?), is arranged, wherein the control unit (6, 6?) is connected to a central control device (13), which controls the drive system (1), via a first interface (14). Control signals for controlling the drive system (1) can be transmitted using the first interface (14). The central control device (13) is additionally connected to the control unit (6) via a second interface (26, 26?), and a switch-off signal can be transmitted from the control unit (6, 6?) to the central control device (13) and/or from the central control device (13) to the control unit (6, 6?) using the second interface (26, 26?).
