The revolute joints on the vehicle body side are again to be regarded as one, kinematically. As a revolute joint is also installed at the wheel carrier side, this component binds considerably more degrees of freedom than the A-arm. The calculation of the degrees of freedom yields:Number of bodies: nB = 2

Number of joints: nJ = 2

Degrees of freedom per joint: fJ1,2 = je 1 (revolute joint)

Number of isolated d.o.f.: r = 0

Number of total d.o.f.: f = 2 ∙ 6 – 2 ∙ (6 – 1) = 2

The last kinematic concept I would like to present is the world’s most popular front axle—the McPherson axle (Fig. 8.9). It is a typical front axle for front-wheel-drive vehicles up to the upper middle class and, as this type of vehicle is the most frequently sold worldwide, it can almost be regarded as the standard in this segment.
