摘要： A control device for a driving unit which comprises an internal combustion engine and a hydrostatic vehicle transmission. The hydraulic adjusting members of the control unit are in response to a relief of pressure automatically by spring force moved to their starting position and are connected to a control circuit which is connectable to the pressure line of a constant delivery pump and is also by a control member connectable to a fluid return line for purposes of setting a control pressure. An adjustable measuring orifice of a limit load control is arranged in the above mentioned pressure line and, when looking in flow direction, is located ahead of the connection of the control member. The control member of the adjustable orifice is connected, for instance, to the gas pedal of the internal combustion engine. A check valve is arranged in a conduit extending from the limit load control to the control circuit of the hydrostatic transmission. In response to the setting of the control member to the maximum possible control pressure, the control circuit is in continuous communication with the return line through a predetermined throttling cross section.

摘要： A hydrostatic vehicle transmission with a primary and/or secondary part adjustable as to its delivery and its absorption capacity respectively. The hydraulic adjusting elements of said primary and/or secondary part are automatically by spring force adjusted in the direction toward their starting position and are connected to a control circuit which is adapted to be connected to the pressure conduit of a constant delivery pump and is also adapted for controlling the control pressure to be connected to a return line by means of a control member. An adjustable orifice of a limit load control is arranged in the pressure line, which orifice is arranged ahead of the connection of the control member when looking in flow direction. The adjusting member of said limit load control may for instance be connected to the gas pedal or manually operable gas lever of an internal combustion engine for instance a Diesel engine while the hydrostatic vehicle transmission also serves as vehicle brake. The brake pedal of the vehicle is operatively connected to a control member which is operable to control the control pressure in the flow direction ahead of the limit load control. This connection is such that in response to the actuation of the brake pedal, the control pressure will be reduced.
