3.3.5. The analysis of results of check on completely slowed down car

Fig. 3.58. Position of couplings of the hydrotransformer



Frequency of rotation of a bent shaft of the engine on completely slowed down car on ranges of "D" and "R" is more than nominal rate:
– low pressure in a hydraulic system of management;
– slipping (pro-slipping) of a brake of the first transfer and transfer of a backing.
Frequency of rotation of a bent shaft of the engine on completely slowed down car only on the range of "D" is more than nominal rate:
– slipping (pro-slipping) of the coupling of the lowering transfer.
Frequency of rotation of a bent shaft of the engine on completely slowed down car only on the range of "R" is more than nominal rate:
– slipping (pro-slipping) of the coupling of a backing.
Frequency of rotation of a bent shaft of the engine on completely slowed down car on ranges of "D" and "R" is less than nominal rate:
– the hydrotransformer is faulty;
– insufficient (inappropriate) output engine capacity.
