Abstract: A method is provided for connection for the cost-effective control of an electronic motor by single-cable technology having a high protection class, wherein the connector technology which is known per se is combined with the terminal box technology which is known per se, and the single cable is pre-assembled with connectors without a high protection class, and, with the terminal box of the electronic motor open, the connectors are inserted into the associated sockets, and the pre-assembled single cable is inlaid into a combined strain relief and earthing shell formed in the terminal box, and a terminal box base is firmly closed by a terminal box lid.

Abstract: A drive system includes at least one drive unit, and at least one control device which at least partially influences the functionality of the drive unit and is connected to the drive unit along a connection region such that a thermal bridge is formed, and wherein the waste heat produced inside the thermal bridge during operation of the system, caused by the respective operating temperature of the drive unit and/or control device, can be discharged from the connection region by at least one heat pipe.

Abstract: A level control for vehicles has at least one air spring cushioning a vehicle body relative to a vehicle axle. A compressed air generator is connected to the air spring by an air dryer and to the atmosphere by a check valve opening in the intake direction of the generator. The air spring can be connected to the atmosphere for discharge via a pneumatically controllable first directional valve. The air spring pressure is applied to a pneumatic control input of the first directional valve via a second controllable directional valve. The input of the first directional valve can be connected to the atmosphere for ending discharge of the spring. A line with a compressed air accumulator branches off from the air spring supply line via a first changeover valve. The accumulator is connected to the intake side of the generator via a second changeover valve.

Abstract: A drive for inducing pivoting rotational and linear movements includes a drive unit comprising two coaxial motors and having a pivot axis and a rotation axis normal to the pivot axis, and a drive element formed as a linear drive. The drive unit operated to induce swinging movements about the pivot axis and rotational movements about the rotation axis is interchangeably and releasably connectable to the linear drive. A transmission device interconnects the drive unit with the linear drive.
