摘要： A hydromechanical transmission has a hydraulic pump-driven hydraulic motor of a hydrostatic continuously variable transmission and a mechanical multi-step variable speed transmission connected to a drive shaft of the hydraulic motor, which can be shifted into operation by a gear shifting device. In order to adapt the hydromechanical transmission with as compact as possible a design to diverse installation cases with little effort, the gear shifting device is arranged directly adjacent to the hydraulic motor and is consolidated with the latter into a preassembled constructional unit.

摘要： A working machine, such as an industrial truck, having a spring-loaded brake having a braking position and a release position and controlled by a brake valve producing a brake-release pressure. The brake valve is operatively connected to a service brake input device, such as a brake pedal, and can be acted upon in the direction of a reduction in the brake-release pressure arising at the spring-loaded brake when the service brake input device is actuated. It being possible, on actuation, for the service brake input device to be operatively connected to a pre-stressed spring device, which is operatively connected to the brake valve and can be acted upon in the direction of an increase in the spring force on increasing actuation of the service brake input device.

摘要： A method for an operation of a forestry winch, which has a rope drum driven by a drive motor and on which a rope is wound up, and has a rope ejector roller for the rope driven by an additional drive motor, whereby the rope is guided from the rope drum to the rope ejector roller and is deflected on the rope ejector roller. The drive motor of the rope drum and the additional drive motor of the rope ejector roller are operated so that when the rope is unspooled from the rope drum, and when the rope is wound up onto the rope drum, a minimum rope pre-tension, in particular a constant minimum rope pre-tension, is generated in the segment of the rope between the rope drum and the rope ejector roller.

摘要： A machine (1) has a rotor (3) located so that it can rotate in a housing (2). The rotor is located at least partly in fluid, such as coolant. To provide a machine which has lower losses with a higher cooling capacity, the housing pressure can be reduced so that the fluid transitions into the two-phase range. In one embodiment, the housing pressure can be reduced by a suction device (7).

摘要： This invention relates to a device to reduce pulsations on a hydrostatic positive displacement units, such as an axial or radial piston machine working both as a pump and as a motor with a reversible direction of rotation. In the displacement units, at least one piston is mounted so that it can move longitudinally in a cylinder bore which forms a cylinder chamber. The device has a buffer element which is in communication with the high-pressure side and can be brought into connection with the cylinder chamber. The device reduces pulsations on hydrostatic positive displacement units by which the reversing actions of the cylinder chambers are optimized and the pulsations are effectively minimized in a broad bandwidth of operating conditions. A switchable valve, in particular a non-return valve which opens toward the cylinder chamber is located in a connecting channel between the buffer element and the cylinder chamber.
