8.4. Possible malfunctions of a running gear, their reason and elimination methods

Kinds of deterioration of tyres at wrong adjustment of disorder and a convergence of wheels

I – normal deterioration of a protector;

II – the convergence of forward wheels (the right wheel, the rear view) is increased;

III – a negative convergence of forward wheels (the right wheel, the rear view);

IV – a negative corner of disorder of forward wheels (the right wheel, the rear view);

V – a negative corner of disorder of forward wheels (the left wheel, the rear view);

VI – a negative corner of disorder of back wheels owing to a deflection of a beam of the back bridge (the right wheel, the rear view)

Kinds of deterioration of tyres at abnormal pressure of air in tyres, the big disbalance of wheels or intensive braking

I – air elevated pressure in the tyre;

II – the lowered pressure in the tyre;

III – the wheel disbalance exceeds admissible limits;

IV – the intensive braking accompanied «юзом» of wheels
