A multi-link suspension is a type of independent vehicle suspension having three or more control links per wheel. [1] These arms do not have to be of equal length, and may be angled away from their "obvious" direction. It was first introduced in the late 1960s on the Mercedes-Benz C111 [2] and later on their W201 and W124 series. [3] [4]
The intention of Ackermann geometry is to avoid the need for tyres to slip sideways when following the path around a curve. [3] The geometrical solution to this is for all wheels to have their axles arranged as radii of circles with a common centre point. As the rear wheels are fixed, this centre point must be on a line extended from the rear axle.
The 4-Wheel & Off-Road "4x4 of the Year" award [4] is one of the most prestigious in the automotive industry, bestowed annually upon a new factory 4x4 pickup truck or SUV that excels in five categories: Ride and Drive, Mechanical, Interior, Exterior, Four-Wheeling Attributes, and Empirical Data. Winners of the 4x4 of the Year award:
Because the wheels are not constrained to remain perpendicular to a flat road surface in turning, braking, and varying load conditions, control of the wheel camber is an important issue. Swinging-arm was common in small cars that were sprung softly, and could carry large loads, because the camber is independent of load.
Thus, the weight of the vehicle tends to rotate the wheel about the kingpin back to this position. The kingpin inclination also contributes to the scrub radius of the steered wheel, the distance between the centre of the tyre contact patch and where the kingpin axis intersects the ground. If these points coincide, the scrub radius is zero.
Trailing-arm designs in live axle setups often use just two or three links and a Panhard rod to locate the wheel laterally. A trailing arm design can also be used in an independent suspension arrangement. Each wheel hub is located only by a large, roughly triangular arm that pivots at one point, ahead of the wheel. Seen from the side, this arm ...
In turns, the outside wheel is often subjected to adverse camber angles when the inside wheel hits a bump, which can suddenly reduce cornering grip and destabilize the vehicle. If one wheel on a beam axle slips off a steep incline or is knocked to one side by a rock at high speed, the other wheel will also follow because of the physical ...
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.
