Figure 1
The front axle is a steel structure with a double-T cross-section
at the end of which the stub axles are articulated.
The stub axle articulation is made with tapered pins integral
with the axle body and by means of four bearings with rollers
driven in with interference in the holes of the stub axle
overhangs.
The wheel hubs are supported by two tapered roller bearings, set
right, lubricated with oil, mounted on the shank of the stub axle.
The bearings need no adjustment; their end float is obtained
by tightening the retaining ring nut to torque.
The disc brake is the ”KNORR” type.
The brake calliper is fitted with:
- an angle of 57
° on axles 5876/4 and 5876/2 without
parking brake;
- an angle of 0
° on axle 5876/5 - 5886/5 with parking brake.
