     Exercise 17. Read the following text. Translate it. Use the words given below.

     Steering

    The steering is of rack-and-pinion type and is power-assisted. The number of
steering wheel turns lock-to-lock is 3.2. The turning circle diameter is 35 ft 6 in. (10.9
m). The three-spoke steering wheel has an extra thick rim and is inclined at 28o to
the vertical plane, which gives restful seating to drivers of virtually any stature. In
addition, it is axially adjustable by 2 in. (50 mm) along the steering column.
    The rack-and-pinion design ensures fast and faithful response to the steering
wheel. It is highly accurate and has no backlash. The effect of suspension spring
deflection on the front wheel angels has been minimised. The steering gear is
permanently lubricated and needs no maintenance.
    The steering system is mounted in well-proportioned rubber bushes which,
together with the front-wheel suspension, effectively absorb the shocks from
irregularities in the road surface at all speeds. The system also provides the driver
with the best possible information on what is happening between the tyres and the
road surface.
    The steering servo acts by hydraulic pressure directly on the rack and is of
“progressive type”, i.e. it provides increasing assistance towards each lock, which is
particulary useful when parking the car in confined spaces.
