Front wheel hub - section
The front wheel hub is a fairly complex forging (conceptually corresponding to a similar node in Skoda Felicia and Favorit cars). In the front wheel hub there is a double-row angular contact ball bearing, into which a driver with an internal splined cylindrical surface is inserted for the splined end of the drive shaft. The drive shaft is fixed in the leash with a self-locking nut with a washer. The nut has an external wrench dodecahedron, M20x1.5 thread, tightening 290 Nm±10% (see fig. View B - Mounting reamer of stub axle assembly, tie rod, propeller shaft and lower swing arm mounting).
At the lower ball joint, the seating surface of the pin is conical-cylindrical.
A brake disc with internal air cooling is screwed to the leash. The brake disc has five holes (corresponding to the threaded holes in the driver) for fastening a car wheel.
On the front wheel hub there are also lugs designed for fastening the brake caliper, as well as holes for the bolts for fastening the brake disc casing.
On the rear side there are also oriented control levers, into the eyes of which ball joints of control rods are inserted, fixed with nuts.
In the upper part of the front wheel hub there is an eye with a cut groove, in which, after insertion, the lower part of the telescopic shock absorber of the elastic assembly is fixed with a horizontal tightening bolt. The shock absorber bracket is also put on this bolt in the axis of the section (see fig. View E - Mounting the front spring assembly to the front wheel hub assembly). in the body (at the top) the elastic assembly is screwed with a lock nut to the fixing plate (see fig. View F - Fastening the front spring assembly to the body). The axis of the eye, and consequently, the telescopic shock absorber deviates from the axis of the leash by 98°3'±15".
