摘要:
A method is provided which forms a closed section hollow structural element by performing the following steps which include press forming an upper sheet metal component configured with two primary parallel downstanding interface flanges; press forming a lower sheet metal component configured with two primary parallel upstanding interface flanges; complementarily trimming the downstanding interface flanges and the upstanding interface flanges using five-axis laser cutting; and butt welding the interface flanges of the upper and lower sheet metal components to one another to form a continuous hollow structural element of variable cross section.

A bumper for a closure, such as a tailgate, acts between the tailgate and a frame to bias a striker in to engagement with a latch. The bumper is moved to a retracted position during closing to reduce the force needed to close the tailgate. After latching, the bumper is conditioned to an extended position to assert the bias between the tailgate and frame.

A vehicular structural member is provided from a closed section hollow element that utilizes a conventional clamshell configuration but eliminates the overlapped joint of the prior art. It has been proven that for large volume applications such as those dictated by the automotive industry, sheet metal press forming is the most cost-effective method of manufacturing structural components. The present disclosure eliminates the redundant material associated with overlapping or flange type joints in clamshell closed section hollow elements thereby reducing weight and cost.

A door check for an automobile has an arm with a cam formed between oppositely directed flanks. A unitary energy storage component cooperates with the arm to provide progressive resistance to opening and closing and a plurality of stable positions. The unitary energy storage component includes a pair of springs, each connected to shoes that bear against the flanks and load the springs in torsion as the shoes moves along the cam. The unitary energy storage component is formed as an integral unit to facilitate handling and assembly.

A machine for laying a catenary cable or a contact wire of an overhead line extending above a track comprises a machine frame supported on undercarriages for mobility along the track, a storage drum mounted on the machine frame and carrying a reel of the catenary cable or contact wire to be paid out from the storage drum, and a guiding device for the paid-out catenary cable or contact wire. The guiding device is pivotable about a horizontal axis extending in the longitudinal direction of the machine frame and comprises a supporting mast having a longitudinal axis, a guide roller mounted to the supporting mast and arranged to be engaged by the paid-out catenary cable or contact wire, a drive for vertically adjusting the guide roller, and a drive for pivoting the guiding device about the horizontal axis. The guide roller is designed for adjustment relative to the supporting mast in a direction extending perpendicularly to the longitudinal axis thereof and transversely to the longitudinal direction of the machine frame, and a drive is provided for transversely adjusting the guide roller relative to the supporting mast.

An apparatus for regulating the lapping pressure during the lapping of two bevel gears at a lapping machine comprising a device for driving one of the bevel gears and for braking the other bevel gear. A control mechanism for adjusting the desired lapping pressure. A differential pressure transmitter is operatively connected with the control mechanism, said differential pressure transmitter serving to measure the liquid-pressure differential brought about by the bearing load in a hydrostatic bearing of one bevel gear in order to regulate the lapping pressure as a function of the bearing load at the aforesaid drive- and braking device.
