  • Patent number: 11618309
    Abstract: An agricultural work machine comprising a front axle and a rear axle, an internal combustion engine, at least one hybrid module, and a transmission device is disclosed. The internal combustion engine and the hybrid module are each operatively connected to the transmission device with both output power from the internal combustion engine and output power from the hybrid module absorbed via the transmission device. The output powers are transferred together to the rear axle so that rear wheels of the agricultural work machine arranged on the rear axle can be driven. The internal combustion engine is arranged in a front region of the agricultural work machine and the hybrid module is arranged in a rear region of the agricultural work machine. The output powers from the internal combustion engine and the hybrid module are supplied separately to the transmission device.

  • Patent number: 9873296
    Abstract: A method for reducing vehicle oscillations for an agricultural vehicle with a drive engine, a running gear cooperating with the drive engine for driving wheels having pneumatic tires, and a control unit for regulating a tire pressure of at least one tire requires a number of steps. For example, the method includes generating a sensor signal as a function of at least one determined vehicle oscillation and regulating a tire pressure of at least one tire by the control unit as a function of the sensor signal in order to reduce the determined vehicle oscillation.

  • Patent number: 9394894
    Abstract: A vehicle includes a coupling for mounting an implement and a load-controlled hydraulic pump that runs continuously with an engine of the vehicle. The pump draws hydraulic fluid from a low-pressure line region and feeds the hydraulic fluid into a high-pressure line region. The high-pressure line region has a high-pressure connection and the low-pressure line region has a low-pressure connection for supplying the mounted implement. A shutoff valve for blocking the flow of hydraulic fluid to the high-pressure connection is connected upstream of the high-pressure connection in the high-pressure line region.

  • Patent number: 9360005
    Abstract: An auxiliary device for an agricultural working machine includes a hydraulic pump unit designed to pump a hydraulic fluid at a predetermined working pressure; a drive unit connected to the hydraulic pump unit that drives the hydraulic pump unit at the working pressure; a hydraulic drive having a drive-fluid inlet connected to a pump-fluid outlet of the hydraulic pump unit via a pressure line (P1, P2) and a drive-fluid outlet connected to a pump-fluid inlet via a supply line (S); and a fluid exchange device having a fluid supply line connected to the supply line (S) for a controlled supply of the hydraulic fluid from a hydraulic circuit of the working machine and a fluid discharge line connected to the supply line (S) upstream of the fluid supply line for the controlled discharge of the hydraulic fluid from the supply line (S) into the hydraulic circuit.
