Abstract: The invention relates to a reinforced formed part with longitudinal and/or transverse cross-sections which may differ in shape and/or size, with a hollow outer formed part (12) and a highly deformation-resistant open or closed-cell foam filling (14) which is at least partly adjacent to the outer formed part, at least partly fills the inner space in the hollow outer formed part (12) and improves the mechanical deformation resistance of the outer formed part, and a process for producing the formed part, in which a hollow component is made by a prior art process and a foam is introduced into it in such a way that the foam is at least partly in contact with the hollow component and is a snug fit therein or is secured by a prior art securing process, and the use of the formed part as claimed in one of the preceding claims as a bearing component in scaffolding, in frameworks, especially in the building trade, in vehicle manufacture for air, land and waterborne vehicles and the furniture industry.

Abstract: The invention concerns an impact-absorption device, particularly for vehicles, which is attached on one side to the bumper and on the other side to the longitudinal girder or another part of the vehicle-body structure. The device has a non-regenerative deforming unit designed to absorb energy when acted on by a force with a component in the direction of the longitudinal axis of the longitudinal girder. The deforming unit has at least two hollow deforming elements which engage one inside the other, one of which being attached to the bumper while the other is attached to the longitudinal girder of the vehicle. If the device is crushed by a force component acting along its longitudinal axis, the deforming elements are telescoped into each other, deforming the material. The hollow deforming elements (12, 14) have a non-circular, preferably oval or angular, cross-section. In a particularly preferred embodiment, the hollow elements have ribs.

Abstract: A hollow shaft with torque-transmitting structural elements such as toothed gears, cams, disc cams, etc., is optionally provided with secondary shaping elements, such as bearing points, stop faces, hexagonal or ring contours, etc. The new shaft is formed from a starting pipe with a substantially uniform wall thickness, which is widened for the positive (form locking) and non-positive (force-fit) connection to the structural elements and for shaping the secondary shaping elements by internal pressure. The maximum widening of the pipe is under the structural elements or on the secondary shaping elements. The new hollow shaft is characterized in that the wall thickness of pipe (12) under the structural elements (14,18) and optionally secondary shaping elements (16,20) is partly enlarged in the axial direction by material flow compared with the wall thickness of the starting pipe.

Abstract: A hollow shaft is provided with torque transmitting structural elements, such as gear wheels, cams, disk cams, etc. At least one structural element has a noncircular opening for mounting on a discharge pipe (12) with a substantially identical wall thickness and with at least one support body (20) between the pipe (12) and each structural element (14) with noncircular opening. The discharge pipe (12) is so widened by internal pressure for frictional connection to the structural elements (14) that cover a portion thereof that the circumference of the pipe (12) engages on the inner wall of the structural elements (14) and another portion of the pipe circumference engages on the outer wall of the support body (20). Each support body (20) is constructed as a separate component from the structural elements.

Abstract: A universal joint is defined by housing portions integral with tubular drive and driven shafts. The housing member on the drive shaft is of generally concave internal shape and has surface irregularities which, in combination with generally complementary irregularities on an enlarged end portion of spherical shape on the driven shaft, define the bearing races of the joint.
