Just for your information, you will find here under a picture of a complete Salmson rear axle. You will see that there is a tube at the front of the central casing with the shaft inside. In the casing, you have only self-aligning ball bearings plus thrust bearing. Without the shaft and the front bronze bearing there is no angular positioning of the pinion. At the front of this tube there is a large ball joint which go inside the gearbox casing. On a Salmson, all the longitudinal effort goes through this ball joint. The clevis on each side of the rear axle are just for the lateral positioning, the spring leaves sliding inside them. The axis on the top of the clevis are there to avoid the leaves to escape the clevis and eventually for the shock absorber fixation. On your chassis, the springs are fixed on these axes and, to avoid the rotation of the axle around the wheel axis, there are 3 small rods but it is obvious they can’t cope with the effort even with the torque of a small capacity engine. The way they are fixed on the axle is … amateurish. I would be very surprised that this chassis has really been driven and used.
