Double wishbone suspension

The double wishbone suspension is an independent suspension design, which can be used both at the front and at the rear axle. The wheel carrier is run by two arranged transversely to the direction of travel A-arms and a track bar. The design can be readily adapted by changing the link lengths and the location of the pivot points on the requirements of the wheel guidance. In most cases, the upper arm is shorter than the lower ( during compression then the fall is negative, the gauge does not change much ) and slightly tilted forward to reduce brake dive. It emerged from the axle- suspension with double transverse leaf springs by the springs at risk of fracture by less and longitudinally replaced rigid wishbones. In the 1930s she began establishing herself as a front suspension, since the 1970s it has been largely replaced in cars of MacPherson -axis and multi -link suspensions. This type of suspension is today (2014 ) is frequently ( and rear ) used in buses, vans, sports cars and racing. At the rear of the lower arm is often extended by a further rod to a N- shaped member for guiding the wheel carrier about the vertical axis ( in the track ).
