Pic. 3-85. Front wheel drive: 1 - body of the internal hinge; 2 - latch; 3 - cover fastening ring; 4 - wheel drive shaft; 5 - protective cover of the cover; 6 - protective cover; 7 - thrust ring of the cage; 8 - separator; 9 - collar; 10 - ball; 11 - holder of the outer hinge; 12 - retaining ring; 13 - body of the outer hinge
The hinge is protected from dirt and moisture by cover 6, which, in turn, is protected from mechanical damage by cover 5. On the shaft 4 and on the hinge body, the protective cover is held by clamps 9. The internal hinge differs in its design from the outer one in that it has straight grooves. The axial movement of the hinge parts in the housing is limited by the wire clamp 2.
Parts of the inner hinge and individual batches of the outer hinge are sorted by size into several assembly groups, therefore, during the repair, it is not allowed to replace any one part of the hinge. It must be replaced as an assembly. Protective covers 5 and covers 6, clamps 9, ring 3 and retainer 2 can be replaced separately.
