Abstract: A trailer hitch for a vehicle comprises a support tube structure which is to be mounted to a vehicle and which removably carries a hitch ball bar. An engagement structure is provided which firmly locks the ball bar to the support tube structure with the aid of a safety bolt which is axially movably disposed in the ball bar and adapted to project from its end within the support tube structure and to lock the ball bar in the support structure in rattle-free engagement therewith. Preferably, the safety bolt is operable by a mechanism extending through the ball bar and the hitch ball so that the safety bolt cannot be actuated when a trailer tongue is disposed on the hitch ball.

Abstract: A method for producing a cast combination of cylindrical hollow profiles and for casting said combination into a cylinder block or crank housing of an internal combustion engine, wherein cylindrical hollow profiles consisting of a light-metal alloy and containing inlaid hard phases that have been manufactured by successive stages of spray compacting, hot extrusion and hot forming are arranged in a row, the distance between the axes of the hollow profiles corresponding to the cylinder bore center distance of the cylinder block and a light-metal alloy without inlaid hard phases is cast around said profiles. The cast combination is then positioned in a mould that forms the cylinder block and a light-metal material is cast around said combination.

Abstract: A method for producing, by forming techniques, an undercut profile in the outer circumferential face of cylinder liners to be cast in place in a crankcase, characterized by the introduction of a bracing inner core into the cavity of a cylinder liner, the introduction of the cylinder liner equipped with bracing inner core into a first forming die equipped on its working faces with a serrated profile, the pressing of the first forming die against the outer circumferential face of the cylinder liner, thus producing a complementary profile in the outer circumferential face, the introduction of the cylinder liner equipped with bracing inner core into a second forming die equipped on its working faces with a smooth surface, and the pressing of the second forming die against the outer circumferential face of the cylinder liner equipped with the complementary profile.
