Abstract: The object of the present invention relates to a wheel securing system for the securing of wheels to a motor vehicle, exhibiting on a constant pitch circle diameter passage apertures with constantly determined passage aperture diameters, comprising: Wheel bearing units with projecting elements, always arranged on the same pitch circle diameter, for penetrating the passage apertures of the wheel disk in an installed state, whereby the projecting elements exhibit different external dimensions depending on the wheel bearing unit, and securing elements with passage apertures, which interact with the parts of the projecting elements which project out of the passage apertures, these surrounding these passage apertures radially, in order to secure the wheel disks on the projecting parts at least against axial and/or radial displacement, whereby the securing elements exhibit means for compensating for the different external dimensions of the projecting elements, in order to guarantee, with a constant external dimensi

Abstract: An instrument panel for motor vehicles, has individually detachably fitted instruments and units, which consists of an electrically nonconductive material, preferably plastic. The instrument panel has integrated electrical conductors which become operatively connected to electrical terminals associated with the instruments or units when the instruments or units are fitted on. The instruments or units each have a mounting base cooperating with an associated hole provided in the instrument panel, the mounting base having a holder and a clip-nose type tension spring. The positions of the instruments and units can be adjusted in the assembled position to the optimal angle of view of the vehicle operator, which can be achieved by turning the instruments and units.
