"Disobedience" of the front-wheel car Serious
feature of management of the front-wheel car - suddenness of its transition to
"disobedience". It can move very confidently on slippery road where
all other cars slip, and at an input in turn suddenly refuses to turn. Such delusiveness
in behaviour of the car is rather artful: the driver, feeling confident movement
of the car, dulls attention a little, relaxes and at unexpected refusal of the
car to enter into turn it is lost and commits errors. Transition from completely
controllable movement to management loss occurs more promptly, than at the rear-wheel
car, and is frequent without preliminary signs.
 Drivers
should remember constantly this property of the front-wheel car and, operating
it, always to hold a steering wheel both hands. The driver should watch constantly
also that pressure in tyres of forward wheels was strictly identical, pressure
drop in one of tyres worsens at once course stability of the car, there is a withdrawal,
and together with it and propensity to a pulling down of forward wheels. In tyres
of back wheels the car practically is not sensitive to pressure decrease.
 The Volga
automobile factory recommends pressure in tyres of the car VAZ-2108 to support
about 1,9 kgs/sm2. However some drivers, aspiring to increase a resource of tyres
(amortisation run), considerably lift pressure in them, without knowing that it
worsens stability of the car. So, at pressure in tyres more than 2,7 kgs/sm2 the
car becomes capable to unexpected failure of forward wheels in a pulling down,
even on dry asphalt.
Drift of back wheels of the front-wheel car arises extremely seldom.
The cohesive forces created on back wheels, on realisation of force of draught
are not used and at movement without braking are directed only on deduction of
wheels from lateral forces. Drift can occur only at braking, as a rule, on turn
when brake forces will exceed on cohesive force size, and on deduction of wheels
from lateral displacement of cohesive forces does not remain. On slippery road,
more often on descent, drift arises sometimes and at sharp delay of movement by
dump of "gas" or transition to the lowest transfer in TRANSMISSION.
The arisen drift is levelled by the braking or delay termination and giving to
the acceleration car, and at the big drift - and turn of a steering wheel towards
drift, as well as at the car of the classical scheme.
