Hydrostatic gear for a vehicle, e.g. a construction machine, such as a bucket wheel extractor, is configured so that the intake volume to a hydraulic motor is controlled so that measured and desired vehicle velocities match
Hydrostatic gear for a vehicle, e.g. a construction machine, such as a bucket wheel extractor, is configured so that the intake volume to a hydraulic motor is controlled so that measured and desired vehicle velocities match
Hydrostatic gear for a vehicle has at least a hydraulic pump and hydraulic motor (5) with an adjustable intake volume. The gear is operated in an open loop and is driven by the motor, which is accelerated or slowed using an electronic controller (8). The controller is set so that a desired vehicle matches a measured vehicle velocity, by adjustment of the intake volume to the hydraulic motor.
