Abstract: In disc brakes, disturbing noises, such as whistling or squealing, occurring during braking operations can be prevented if the brake shoe, to be pressed against a brake disc by a pressure member, for example a hydraulically actuated piston, is taken along in the circumferential direction of the latter as soon as the brake shoe comes into contact with the brake disc, and is laid against bearing faces of a brake anchor plate. Accordingly, the pressure member is provided, on its end face facing the brake shoe, a pressing element which projects beyond the end face, is transversely movable to a limited extent and returns automatically to its initial position again, and which is arranged in the pressure member so as to be axially displaceable counter to a return force which, in the event of mutual contact between the pressing element and brake shoe, is lower than the pressing force of the pressure member.

Abstract: A brake shoe adjustment device for internally mounted shoe brakes is arranged between mutually neighboring ends of two brake shoes which are connected to each other via a tension spring. To minimize parts, size and cost the adjustment device has two mutually opposite spreading elements, each of which is held by one brake shoe end. One of the elements is equipped with a threaded shank that cooperates with a threaded bore of the other element. The elements are axially displaceable by a worm wheel gear which rotates the shank in response to turning by an adjusting tool.

Abstract: An internal combustion engine arranged in an automotive vehicle with optionally driven units or the like, for example, units driven by way of pulleys. The units extend toward a front if the internal combustion engine is arranged in a front compartment of the automotive vehicle and extend toward the rear beyond the internal combustion engine if the engine is disposed in a rear compartment. The units and optionally their drive elements are fashioned in such a way and/or are mounted to the internal combustion engine in such a manner that, in case of a collision, impact energy is absorbed at the units and/or their fasteners or mounting by the performance of deformation work, by overcoming frictional resistances, and/or by a displacement of viscous substances against a resistance.

Abstract: An arrangement for mounting driven or non-driven assemblies on or to an internal combustion engine mounted in a motor vehicle. The assemblies projecting forward beyond an end of the internal combustion engine when the engine is mounted in a front of the motor vehicle and projecting rearwardly beyond the engine when the engine is mounted in the rear of the motor vehicle. The assemblies are so mounted and/or fastened on or to the internal combustion engine that, in the event of a collision and/or an impact on the assemblies, such assemblies are displaceable in a direction of the internal combustion engine with a zero resistance and without expending any energy absorption.
