Abstract:
In order to ensure in sliding surface bearings a uniform distribution of the load over the bearing metal layer, a phosphate layer serving as a sliding layer has been applied to the bearing metal layer.In order to ensure a high resistantce to scuffing, the sliding layer is formed from an aqueous phosphating solution which contains 1.5 to 5.0 g/l Zn, 12 to 24 g/l Na, 11 to 22 g/l P.sub.2 O.sub.5, 17 to 33 g/l 16 to 30 g/l BF.sub.4, 20 to 39 g/l B(OH).sub.3 and 1.0 to 6.0 g/l NaF.

Abstract:
A piston rod for pistons of reciprocating piston machines is I-shaped in cross-section. In order to effect a reduction in weight that flange of the piston rod which is nearer to the connecting rod and is enbraced as by claws by the forked and hook-shaped end portion of the connecting rod has a smaller width than the flange which is nearer to the piston head.
Abstract:
A roll-formed bushing for sliding surface bearings has no machining allowance in the bearing bore and is made of a strip section and has a butt joint that extends throughout the width of the bearing. In order to reduce the allowances of the bore diameter and the outside diameter of the bearing bushing, the butt joint has been closed by charge carrier beam welding.
Abstract:
In a composite material for sliding surface bearings, a rough metallic surface is provided with a polymeric matrix, which forms a friction contact or sliding layer over the rough base surface. To increase the wear resistance, the matrix contains zinc sulfide and/or barium sulfate in a particle size from 0.1 to 1.0 .mu.m and an average particle size of 0.3 .mu.m.
Abstract:
A safety steering wheel having an impact protector mounted on the hub of the steering wheel and which consists of a collapsed gas bag and a housing which contains a propellant for inflating the gas bag. The impact protector is covered by a cover hood, which is made of soft elastic plastic and reinforced by a reinforcing layer. In order to prevent a bulging of the cover hood by the forces which are exerted by the collapsed gas bag, a frame is provided, which is secured to the carrier for the housing which contains the propellant. The frame surrounds the housing and the gas bag and comprises at least one retaining member, which is integrally joined to the frame and attached to that edge of the frame which faces the driver's compartment. The retaining member when in a rest position extends in front of the collapsed gas bag and in the case of an impact is adapted to be bent up toward the driver's compartment along a straight line. A reinforcing layer is provided, which is made of hard plastic and covers the gas bag, wherein the rated breaking line of the cover hood that is connected to the frame and extends along those sides of the reinforcing layer which are not directly connected to the retaining member.
Abstract:
A cast light metal piston for internal combustion engines is provided with a ceramic insert in those zones which are highly thermally stressed and/or for heat insulation. To form a high-strength bond between the light metal and the insert, high-strength fibers are embedded in the light metal in the zone adjoining the insert.
Abstract:
A material for sliding surface bearings comprises a backing layer of steel and a clad-on layer made of an aluminum-base bearing material. To increase the fatigue limit the material 2 for sliding surface bearings has been heat-treated at 200 to 220.degree. C. for 2 to 12 hours and the bearing material is composed of14 to 18% by weight tin,1.7 to 2.3% by weight copper,balance aluminum.
Abstract:
A roll-formed sliding surface bearing bushing is circular in an installed state and has a butt joint which extends throughout the width of the bushing and is closed in an installed state. To ensure a backlash-free bearing arrangement, the bushing has on its outside peripheral surface a trapezoidal profile, which includes an angle of 1.degree. to 30.degree. with the plane which contains the longitudinal axis of the bushing.
Abstract:
A material for sliding surface bearings comprising a layer of a wrought copper-zinc alloy of thickness of about 0.1 to 1.5 mm inseparably joined to a backing layer of steel or stainless steel. A co-rolled joining strip of copper may be between the two layers.
Abstract:
In order to have a sufficiently large elongation at fracture in conjunction with high strength values, a pressure-diecast steering wheel skeleton consists of an aluminum alloy which is composed of______________________________________ 2.5 to 3.5 % by weight magnesium 0.10 to 0.30 % by weight silicon 0.40 to 0.60 % by weight iron 0.25 to 0.45 % by weight manganese 0.015 to 0.05 % by weight copper 0.035 to 0.085 % by weight zinc balance aluminum. ______________________________________
