Abstract: A drive aggregate for electric vehicles, especially for trackless street vehicles, which is equipped with an electric shunt motor provided with field current control and with a change-speed transmission having at least two forward speeds connected behind the electric shunt motor; the electric shunt-wound motor thereby has a relatively high rated rotational speed in relation to its maximum rotational speed and a relatively reduced field-weakening range whereby the change-speed transmission is an automatic transmission connected with the electric shunt motor by way of a speed-reducing gear while the oil pump of the automatic transmission is driven by an electric motor coordinated thereto which operates at substantially constant rotational speed.
