In vehicles designed to pick up and process crops, drive units affect the ground drive, which is an all-wheel drive, which acts on all of the wheels and/or track roller unit in contact with the ground, electronic controls and actuators perform the control and regulation of the drive units, and control units that control the drive torque at the wheels are used to obtain good traction and minimal slippage of the wheels on the ground. To control the drive torques, sensors are used at particular points, the signals and data of which are processed by the control device in order to predetermine a torque or intake volume requirement. The preselection of torque in the control results in the intake volume of the hydraulic drive motor being regulated. By specifying the intake volume required, it is possible to obtain optimal traction at one or more drive wheels, and to prevent undesired slippage of any one drive wheel in advance.

Electronic control for the drive unit of a vehicle

The present invention relates to a self-propelled forage harvester () that is equipped with a front attachment () and includes a rigid axle (), a transmission () and two wheel gears (), which are installed upstream of the drive wheels () and are coupled with the transmission () in a driving manner, the drive axle () being composed of a center part () and axle carrier units () rigidly flange-connected on the right and left sides of the center part (), each axle carrier unit () including wheel gears () that extend forward, in the direction toward the front attachment ().

A multi-stage gearbox has at least one shifter rod which may be engaged and locked in a predetermined position by at least one locking element. The locking element is coupled to a setting element such that the setting element can be set in at least two different positions relative to the locking element by a control device. A method of controlling such a gearbox includes the step of moving the setting element from a retention position into a shift position by actuating a push-button.

Device for multi-stage gearbox and method of operating

A self-centering dog clutch includes two coupling-parts is arranged in a simple manner such that components serving for centering purposes are not necessary. Contact faces of the two coupling-parts are off-set relative to the rotational axis of the dog clutch. This results in a radial component of force which serves to center the two coupling-parts. The recesses in the first, driven coupling-part have a larger surface area than the drive claws engaging therein of the second, driving coupling-part. The two coupling-parts can thereby rotate against each other through a predetermined angle. This dog clutch is particularly suitable for use with agricultural machines.
