ABSTRACT:
The invention pertains to a body-side mounting for suspension strut (1, 2, 3) or spring shock absorber of a motor vehicle, with a rubber mount (8) effective between the body and suspension strut, predominantly loaded in shear, which is placed between a mount receptacle (7) formed into the body or parts thereof and a spacer (6) joined to the suspension strut, with the mount receptacle and spacer being adjusted to the dimensions of the rubber mount and receiving the latter in the inward spring deflection direction and radially thereto.
The object of the present invention is to create a body-side mounting of the aforesaid type in which the rubber mount itself, when radial forces are introduced, for example, as a result of full steering lock, guarantees a largely constant spring rate and therefore stable steering response.
The object is achieved by the fact that teeth are provided on the inside of the mount receptacle (region 22) and on the outside of the spacer (region 15), which engage in teeth in the rubber mount (regions 16, 19). The teeth prevent the rubber mount, when radial forces are introduced, from shifting from its loaded side to the unloaded side, which would lead to a degressive change in spring stiffness.
