Four chassis mounting points, one for the strut rod top mounting, one for each lateral link, one for the trailing link. The arrangement of the links consists of two lateral links (usually parallel in plan view and of equal lengths) and a single trailing link. The strut top mounting needs only to provide minimal (or no) rotational capability. This is only suitable for rear suspension systems.
Four strut mounting points, one for the strut rod top mounting, one for each lower lateral link and one for the trailing link.
The tri-link strut is dimensioned the same as a normal strut, except that the trailing link and lateral link mountings are all part of, and dimensioned relative to, the knuckle.
The strut and knuckle can be integral or separate.
The king-pin inclination is not applicable. Caster is defined as the amount the strut assembly is 'tilted' (in side view) from the strut datum position.
The front view instant centre (roll centre) is defined by the strut rod axis and the lateral links.
The side view instant centre is defined by the strut rod axis and the trailing link.
