摘要:
A drive arrangement for an electric vehicle has an axle drive device of a portal design with two electric machines for driving the wheels of an axle of the electric vehicle, and at least one electric energy store that can be discharged when an electric machine is operated as a motor and/or can be charged when an electric machine is operated as a generator. The drive arranged is characterized in that the two electric machines (11) of the axle drive device (10) are combined with a respectively assigned transmission (12) in an electric axle to drive the individually suspended wheels (2) of the axle by means of, in each case, one articulated shaft flange (13) via a respective articulated shaft. Frequency converters assigned respectively to the two electric machines are combined in a converter unit.

In a method for determining road clearance of a vehicle, the vehicle is moved relative to a measurement configuration with a reference surface. One or more magnets, which are disposed on the vehicle and assigned preferably each to a defined measurement point on the vehicle, is detected by at least one device for magnetic field measurement. With the help of at least one device for separation measurement, the separation between the measurement configuration and the bottom side of the vehicle is determined. In this way, a rapid, reliable, repeatable and flexibly usable method for the determination of the road clearance of a vehicle is provided. A corresponding device is provided for implementing the method.

A new method and to a new programming tool for creating a user program for a safety controller is disclosed. The new method and programming tool exploit a matrix-type organization of occurring programming tasks. Itemized software components allocated to specific hardware components are combined with aspect blocks that enable programming grouped according to functional control aspects of the system to be controlled.

A process for preparing a black colorant, preferably a black pigment, characterized in that a compound of the Formula (I) is reacted with a compound of the Formula (II) in a molar ratio of 1:2, in the presence of a catalyst which in water at 25° C. has a pK≦4.5. For the definition of R1 to R7, refer to the description; preferably all are H. Likewise claimed are new crystal polymorphs obtainable by this process, and preferably single-phase mixed crystals. Also claimed are synergistic compositions. These compositions exhibit increased light stability in plastics stabilized with basic light stabilizers when they are pigmented with colorants of the invention rather than with known black pigments such as carbon black. The specification also relates, furthermore, to the use of the black colorants of the invention for coloring paints, printing inks and plastics in the mass, and to mulch film, instrument panels, woven fabrics, garden furniture items or elements for the construction industry that are pigmented with said colorants.

A safety switching apparatus for failsafe disconnection of an electrical load has a first and a second connecting terminal for connecting a first signaling switch and a third and a fourth connecting terminal for connecting a second signaling switch. It also has a first and a second output switching element, which are designed to produce a redundant output switching signal. The first connecting terminal is connected to a first potential and the third connecting terminal is connected to a second potential. The potentials differ from one another. In addition, the second connecting terminal is coupled to the first switching element in such a way that the first switching element receives the first potential via the first signaling switch. Likewise, the fourth connecting terminal is coupled to the second switching element in such a way that the second switching element receives the second potential via the second signaling switch. According to one aspect of the invention, a circuit arrangement is provided for determining at least one further potential at the second and/or fourth connecting terminal, and said circuit arrangement is designed to control the redundant output switching signal as a function of the further potential.

The invention relates to a method for producing cellulosed molded articles having a functional effect. The method is characterized by charging cellulosed fibers or films with incorporated ion exchangers having bactericidal metal ions and/or ionic pharmaceutical active substances in such a manner that a depot of these active substances is built up in the fiber. Said depot time releases the active substances in the amount of the corresponding equivalent concentration when the fibers and films are used in aqueous solutions. The invention also relates to molded articles produced according to the inventive method.
摘要:
A vehicle having an electric drive device and an energy storage device which is arranged in a housing is disclosed. The energy storage device is formed from a plurality of cells. The housing includes a plurality of partitioning devices, with the result that at least one partitioning device is positioned between two cells. The housing of the energy storage device is connected both to a cooling air intake duct, having an inlet opening, and to a cooling air outflow duct, having an outlet opening. At least one partitioning device is configured in such a way that a plurality of cooling ducts are formed between the cells, and cooling air can flow through the cooling ducts in order to cool the energy storage device.
