Pintle Pintle A pintle is a pin or bolt, usually inserted into a gudgeon, which is used as part of a pivot or hinge. Other applications include pintle and lunette ring for towing, and pintle pins securing casters in furniture. Pintle/gudgeon sets have many applications, for example: in sailing to hold the rudder onto the boat; in transportation a pincer-type device clamps through a lunette ring on the tongue of a trailer; in controllable solid rocket motors a plug moves into and out of the motor throat to control thrust. In electrical cubicle manufacture, a pintle hinge is a hinge with
Dual pivot steering geometry Dual pivot steering geometry Dual-pivot steering geometry (also known as virtual pivot) is a geometric arrangement of linkages in the steering of a car designed to reduce or eliminate scrub radius by moving the pivot point of the king pin outboard, in order to improve steering precision and straight line stability. It is typically used with a MacPherson strut, but can also be applied to a double wishbone suspension. 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
