Figure 1
ARTICULATED QUADRILATERAL SUSPENSION WITH TRANSVERSE LEAF SPRING
(vehicles 29l - 35s - 35c)
The suspension comprises:
- two top triangular suspension arms, composed of a sheet-metal shell, connected by elastic bushings to the crosspiece by pins
articulated to the stub axle;
- two bottom triangular suspension arms, composed of two sheet-metal half-shells welded together, connected by elastic
bushings with metal reinforcement to the crosspiece and pins articulated to the stub axle.
The bottom suspension arms have reaction points for the leaf spring and the bottom mountings of the shock absorbers;
- a single-blade leaf spring, made of composite material for axles 5817 mounted on vehicles 29 L and 35 S, steel for axles 5818
mounted on vehicles 35 C; the spring is kept inside the crosspiece by two top reaction plugs fitted on the ends of the spring
housed in the seats in the bottom suspension arms.
The steel leaf spring, due to the resistance it provides for the rolling movements of the vehicle, makes mounting the front
stabilizer bar superfluous;
- two double-acting hydraulic shock absorbers with integrated limit stops;
- stabilizer bar on vehicles 29 L - 35 S.
