摘要： An adjusting arrangement for a hydraulic pump with a variable flow quantity, having an operating cylinder located in a neutral position through the intermediary of a positively-acting resetting device, the piston of which is adjustable dependent upon the actual discharge pressure and dependent upon a parameter proportional to the actual discharge flow quantity into a position corresponding to the rated discharge flow quantity with consideration being given to the limiting value for maximum power output, maximum discharge pressure, maximum discharge flow quantity and, as required, the flow direction. An electronic control arrangement receives electrical signals corresponding to the rated discharge flow quantity and the actual discharge flow quantity and the actual pressure, which processes these signals under calculation of the actual power output and the actual pressure, and generates corresponding setting signals for the adjustment of the operating cylinder.

摘要： A torque control device for an adjustable hydropump is described which is based on an output control device in which the output control is determined as a function of the output pressure of the hydropump and a pressure in a working pressure control line. For this purpose a torque valve is provided whose closure power is determined by a measuring spring or set of springs connected with the pump control member and pretensioned depending on the output setting. The torque valve connects the working pressure control line with the pressureless outlet depending on the pressure in the working pressure control line and the pretension of the measuring spring. The torque valve can be fixed on to the hydropump as a separate unit and the control characteristic can be changed from outside by adjustment of the measuring spring.

摘要： A hydrostatic driving gear is described comprising a primary unit rotationally driven by a driving engine and a secondary unit rotationally driving an actuator. Each unit comprises a variable displacement hydraulic engine, in particular an axial piston engine. They cooperate in an open circuit. The primary unit and secondary unit each have a displacement adjusting device and can be continuously adjusted in respect of their direction of displacement through a zero displacement center position in two directions of displacement. The displacement adjusting device of the primary unit has associated with it a pressure flow controller which holds the working pressure at a constant presettable value. The displacement adjusting device of the secondary unit has associated with it a speed of rotation detecting device, having a position sensor to detect the flow setting. The secondary unit also has associated with it a speed detecting device and an electronic controller is provided which detects the displacement setting of the secondary unit and its actual speed of rotation and compares it with a predetermined desired actual speed of rotation and adjusts the controller correspondingly. A secondary controlled hydrostatic driving gear in an open circuit is provided which makes four-quadrant operation possible.
