In a demonstration, a metal sphere dropped on amorphous steel bounced significantly longer than the same metal sphere dropped on crystalline steel. [ 4 ] The lack of grain boundaries in a metallic glass eliminates grain-boundary corrosion—a common problem in high-strength alloys produced by precipitation hardening and sensitized stainless steels.
Double wishbone suspension (front) on a Saab Quantum IV. The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped or L-shaped. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut.
In either case, the difference is that the single bottom wishbone is replaced by a pair of suspension links forming a trapezoidal four-bar linkage. This allows the kingpin to pivot about a pivot point nearer the center of the wheel's contact patch instead of the traditional pivot point at the ball joint of the bottom wishbone. [2]
Pull-rod suspension and push-rod suspension refer to a specialised type of automotive suspension system which is largely based on a double-wishbone system, incorporating elements of the commonly used MacPherson strut. [1] In cars, suspension refers to the system by which the vehicle maintains contact between all of its wheels and the ground.
Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump on the road) independently of the others. This is contrasted with a beam axle or deDion axle system in which the wheels are linked. "Independent" refers to the motion or path of movement of the wheels or ...
Liquid Metal may refer to: A liquid metal, which has a relatively low melting point, such as mercury, tin or lead; Any metal in a liquid state; Mercury, the only metal to be liquid at room temperature; Liquid metallic hydrogen; Liquidmetal, a type of metallic glass; Liquid Metal (Sirius XM), a radio channel
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The ...
