摘要:
A device for joining by a laser beam two components along a ring-shaped contact zone, where a first of the two components is transmissive for the laser beam and a second of the two components is absorptive for the laser beam. The device includes a receptacle configured to affix the absorptive component and an internal clamping chuck configured for placement on the transmissive component within an open inside area of the contact zone. The device also includes a pressure element with an open inside area that is larger than an extension of the contact zone, a laser source configured to emit the laser beam, and a rotatable holding wheel. The pressure element is connected to the internal clamping chuck via an external axial bearing, the holding wheel and an internal axial bearing so as to transmit to the internal clamping chuck contact pressure exerted on the pressure element.

The invention is directed to packaging comprising a multiple-layer material construction with a break line which is formed by a line-shaped, successive arrangement of blind holes separated by webs and in which the multiple-layer material construction comprises at least one layer which absorbs laser radiation and a layer which reflects this laser radiation. A radiation-absorbing layer forms the surface layer of the packaging, and the blind holes of the surface layer extend into the packaging until the reflecting layer, and the web widths are substantially constant over the depths of the blind holes so that there are abrupt jumps in material thickness along the break line, and a clearly audible noise is generated when these jumps in material thickness are overcome when the break line tears. The invention is further directed to a method for producing packaging of this kind.
摘要:
In order to prevent mechanical loading of a predetermined breaking line integrated in an airbag covering when arranging an ejection channel by a material engagement, it is proposed, in accordance with the invention, that the material engagement be produced by laser transmission welding, wherein the contact pressing force required for this purpose is applied by a frictional engagement or positive engagement encompassing the joining surfaces to be welded.
摘要:
A regulator (27) automatically adjusts a drive cable (3, 4) or Bowden cable (15) to drive a vehicle brake by means of a drive element such as a brake lever or a handbrake lever (21), the regulator (27) comprising two pivotally supported resetting arms (1, 9) prestressed by at least one spring element (13) and which can be connected each to the drive cable (3, 4) resp. leading to the brakes, further comprising a blocking system (28) to block the pivoting motion about a common pivot axis (19) of the resetting arms (1, 9) in case of actuation of the drive element coupled by a Bowden cable (15) to the resetting arms (1, 9). At least one guidance inset (7) is seated in irrotational manner in a clearance (5) of a resetting arm (1) as a pivot bearing for the other resetting arm (9), the latter being supported at the guidance inset (7) so as to be pivotable about the pivot axis (19) and the blocking system (28) is supported at or in the guide inset (7) so as to be radially displaceable about the pivot axis (19).

摘要:
A reciprocating piston machine includes at least one piston movably supported within a cylinder bore. The reciprocating piston machine further includes a valve device interacting with the at least one piston. The valve device has a valve plate and a suction valve provided with a plurality of valve fingers.
