Four wheel car 3

A rocker (in blue) carrying two wheels is pivoted one each side of the car. The rockers are connected together via a bevel gear differential.
This arrangement ensures:
- The four wheels always contact the uneven ground.
- The car chassis (in yellow) has a definite position, although it is suspended on two coaxial revolution joints.
- The oscillation of the chassis is reduced because:
Ab = (Ar1 + Ar2) / 2
Ab is the oscillating angle of the chassis.
Ar1 and Ar2 are the oscillating angles of the rockers
The last scenes of the video show when rocker 1 is immobile, the oscillating angle of the chassis is a half of the rocker 2 oscillating angle.
