The variation of the rigid bridge can be considered a solution halfway between the dependent wheel suspension and the independent wheel suspension. So, in used BMW xdrive 30d for sale, that aspect needs to be considered, as well. In this case, the wheels are not mounted on the axle of the bridge and the rigid connection has been replaced by a U-shaped or T-shaped bridge designed to allow a certain twist. It is, therefore, a semi-independent wheel system where the wheels, connected by a lever arm to the bridge, are able to exploit the deformation of the system to obtain a certain relative motion. Â
Excellent Resistance
Although different from the rigid bridge, this solution retains the characteristic of keeping the wheels always perpendicular, guaranteeing excellent resistance to transverse forces when cornering. During symmetrical shaking, the bridge rotates around the axis identified by the joint between the two centers of the bushings. A buyer should know when he decides to do BMW xdrive 30d review, during the excursion it does not cause camber or convergence variations if the elastic failures of the structure, usually very small, are excluded. In asymmetrical shakes the crosspiece is subjected to torsion and, due to its deformation, the arms can oscillate each with different angles around coincident axes. The shape of the crossbar also ensures high bending stiffness accompanied by a modest torsional stiffness ensuring very low camber angle variations.Â
Subjected To Torsion
In asymmetrical shakes the crosspiece is subjected to torsion and, due to its deformation, the arms can oscillate each with different angles around coincident axes. The shape of crossbar also ensures high bending stiffness accompanied by a modest torsional stiffness ensuring very low camber angle variations. Therefore, by adequately designing the beam section and its position with respect to the wheel center, it is possible to set the camber and convergence variation. The direction of the axle of the bush is not parallel to the transversal axis of the car so as to limit the convergence variation due to the lateral load on the curve.Â
Total Recovery
If a buyer ready to pay the BMW xdrive 30d price, he should know that as well, In fact, the bending of the arms, due to the centrifugal force, causes additional steering on the rear axle (self-steering). A further system to limit the lateral deformations of the arms, due to the effect of cornering forces, is given by the use of a Panhard bar. Ultimately the Twisting Bridge guarantees an almost total recovery of the camber in asymmetrical shaking; the possibility of controlling roll convergence; a moderate elasticity under longitudinal load, the sensitivity of the convergence angle to the lateral and longitudinal loads and low roll stiffness. It takes up less space and is easier to make than the old Rigid ancestor but, more importantly, it guarantees greater comfort, stability and driving a pleasure. If well designed it is even superior to the branded system (at the rear) but not yet to the transverse-based system.
