DC propulsion with start-up assistance for surface transport vehicles, in particular diesel vehicles in co-operation.

摘要

DC drive with start-up support for industrial trucks, in particular drawbar vehicles with a walking operator, having a DC motor, a pulse-controlled switch for the DC motor, a travel-enable switch (for example drawbar switch) which is closed in order to release a brake, a travel switch whose actuation direction determines the direction of rotation of the DC motor and whose deflection determines the magnitude of a set value signal which is transmitted to a pulse control value generator via a ramp circuit as actuation value, which pulse control value generator generates the control pulses for the switch, a starting control value generator which bypasses the ramp circuit being provided, which starting control value generator is actuated optionally by the travel-enable switch and by the travel switch and/or a separate switch or automatically by an inclination generator when the vehicle is to approach an incline, in particular counter to the direction of the drawbar in a drawbar vehicle and generates a starting control value for the pulse control value generator.
