摘要： A safety steering column assembly for automobiles comprising a steering shaft of variable axial length for connecting a steering wheel with a steering gear mechanism. A portion of the steering shaft adjacent the steering wheel is surrounded by a guide and support tube in which a bearing for turnably supporting the steering shaft is mounted. The guide and support tube, in turn, is surrounded by a corrugated tube serving as an impact absorber in which the corrugations of the tube are compressed into a block to reduce the axial length thereof. The stiffness of the corrugations of the corrugated tube varies along the length of the latter and the end of the corrugated tube distance from the steering wheel is fixedly attached to the guide and support tube, whereas the other end adjacent the steering wheel is releasably attached by means of a bracket to a portion of the body of the automobile so that upon impact on the steering wheel, for instance when during an accident the body of the driver hits the steering wheel, the corrugated tube is stressed in tension, whereby the compressed corrugations of different stiffness are gradually extended to provide a gradually increasing impact absorbing force.

摘要： A method for the continuous production of exhaust pipes for automotive vehicles comprises the steps of continuously withdrawing an elongated substantially flat metal strip from a coil and subsequently bending and forming the moving strip into a longitudinally slitted tube strand. The opposite faces of the slitted pipe strand are then welded together and subsequently the pipe strand, while still moving, is severed into pipe sections of predetermined length and the pipe sections are then transferred to at least one bending apparatus for bending the pipe sections into exhaust pipes with predetermined bends; and an apparatus for carrying out the above method.

摘要： Apparatus for forming a corrugated tube from a smooth walled starting tube comprises a pair of receiving mandrels aligned spaced from each other along a preferably vertical axis and movable toward and away from each other to be engaged in opposite end portions of a starting tube. The halves of split corrugation forming discs and the halves of an end member above the uppermost of the discs, coupled together for limited movement in axial direction, are respectively carried and guided for movement in axial direction by a pair of clamping jaws tiltable between an open position permitting to align a starting tube with the mandrels and a closed position closing the split discs and the split end member and fluid tightly clamping opposite end portions of the starting tube located about said mandrels respectively between one of the mandrels and the closed end member and between the other mandrel and the clamping jaws. A channel for introducing pressure fluid into the interior of the starting tube leads through the other mandrel, while a ventilating channel in which a ventilating valve is arranged serves to discharge air from the starting tube during introduction of pressure fluid thereinto. A fluid operated cylinder and piston unit cooperates with the end member and the receiving mandrel engaged thereby for moving both elements in axial direction towards the other mandrel to thereby offset the starting tube and to deform the same into a corrugated tube.
