An input device includes a fixed unit, a rotary member rotatably supported by the fixed unit, a rotation-detecting unit that detects a rotation angle of the rotary member, a brake-applying unit that applies a braking force to the rotary member, a torque-applying unit that applies a driving torque to the rotary member, and a control unit that controls the brake-applying unit and the torque-applying unit. The brake-applying unit includes magnetorheological fluid, a brake-applying coil that applies a magnetic field to the magnetorheological fluid, a shaft to which braking torque that changes with viscosity of the magnetorheological fluid is applied, and a transmission gear provided on the shaft and that is in mesh with a gear provided on the rotary member. The shaft is positioned on an outer side with respect to the rotary member in a radial direction of the rotary member.

A modular control apparatus for actuating hydraulic valve systems includes an actuating section including a tilting control member and a plurality of control rods provided with a pusher, which interacts with the control member so as to translate the control rods in the longitudinal direction, a sensor section including a plurality of sensor members suitable to detect a movement in the longitudinal direction of said control rods and a blocking section comprising a blocking device that is capable of individually blocking in the longitudinal direction each of said control rods. The actuating section can be alternately connected to the blocking section or to the sensor section so that the sensor section can be directly connected to the actuating section, detecting the longitudinal movement of the control rods also if the blocking section is not present.

An operator control device has an actuation unit on a console unit. The actuation unit movable between an idle position and one or more actuation positions. The actuation unit is fixable in the idle position by a retaining device. In order to leave the idle position, it is necessary to overcome a retaining force provided by the retaining device. The retaining device has a coupling device with a coupling element that is magnetically couplable to the actuation unit and to the console unit in order to magnetically fix the actuation unit in at least the idle position.

A cruise control system for work machines. The system comprises one or more levers for controlling the velocity of the work machine and one or more magnet assemblies. The magnet assemblies comprise means of overcoming the neutral bias of a control lever so that the velocity of the work machine may be maintained without manual input from the operator. The magnets may act directly upon a control lever or a surface adjacent a control lever. Additional controls may be employed to set a maximum cruising speed for the work machine when cruise control is engaged.
