Abstract: The invention relates to a motor vehicle steering shaft with two shaft sections which are telescopically guided in one another and have corresponding profile cross-sections, between which at least one row of balls is fitted in. The row of balls are each arranged in the axial direction and are used as a driver element operating in the rotating direction. According to the invention, one axial stop respectively is assigned to the first and the last ball of the ball row. The stops are positioned on opposite shaft sections and at least one of these stops being plastically deformable.

Abstract: A heating or cooling arrangement in a motor vehicle is provided with an equipment block, in which a heat exchanger, an evaporator, a condenser or a cooler are arranged on the inlet and outlet pipes. The heat exchanger, evaporator, condenser or cooler is slid into the equipment block as a preassembled heating or cooling unit. The equipment block is provided with clamping elements by which inlet and outlet pipes arranged on the heat exchanger, the evaporator, the condenser or the cooler in a preassembled manner are connected with the equipment block.

Abstract: A heating or air conditioning system for a passenger compartment of a motor vehicle has a heat exchanger which is arranged in a cooling water circuit of an internal combustion engine and through which an air stream passes. A supplementary electric heater through which the same air stream can flow is also provided. In order to design the heating or air conditioning system in such a way that a separate installation space is not necessary for the installation of the supplementary electric heater, the supplementary electric heater is physically integrated into the heat exchanger. The supplementary electric heater includes a plurality of electric heating rod assemblies arranged between water ducts of the heat exchanger which extend parallel with one another along the air passage surface of the heat exchanger.

Abstract: A steering column in a motor vehicle having a steering shaft which, in the event of a crash, can be displaced axially in the direction of the vehicle front by a load on the steering wheel. The steering column has a shell element around the steering shaft adjoining the steering wheel which can be divided by the displacement of the steering wheel for reducing the displacement resistance. The shell element is divided into at least two parts approximately in the axial direction of the steering shaft. The steering wheel and the steering shaft press the shell parts of the shell element apart radially to the outside in the event of an axial displacement.

Abstract: An assembly plant for the series assembly of vehicles has a main assembly line and associated assembly works for relatively complex vehicle parts to be supplied "just in time". Simpler assembly components and small and standard components are held in readiness in a central component store and supplied from there to the assembly line. Stores for large components are arranged near to the corresponding assembly point. The overall conveying section is divided into a plurality of mutually adjoining U-shaped conveying loops. Provided between each of the assembly shops and the central component store, on the one hand, and the main assembly line, on the other, there are in each case feeder systems.

Abstract: A process and apparatus for repairing small paint defects in powder paint coats. In the process, the paint defect is hollowed out, a filler body, which is adapted to the recess with respect to shape and/or volume, is placed in the recess, the filler body is connected with the powder paint coat surrounding the recess and hardened. In order to improve the quality of this repair, after inserting the filler body, pressure is exercised on the filler body at least at the start of the connecting and/or at least at the start of the hardening.

Abstract: A process for repairing relatively small paint faults in powder coating layers, in which, in the region of the faulty point, a cutout is introduced into the powder coating layer with precisely defined dimensions with respect to its area and also with respect to its depth. A filler made of powder coating and/or a pre-product of the powder coating is introduced into the cutout. The filler is dimensioned to correspond to the volume of the cutout, in particular corresponding to the dimensions of the cutout, and is coherent. The filler introduced is joined, in particular bonded, to the powder coating layer arranged outside the cutout.
