   Exercise 20. Read the following text. Translate it with the help of a dictionary.

   Rear axle
    The rear axle is straight and rigid, and is very firmly and accurately located
laterally. This feature, combined with the short overhands of the car, is one of the
most important reasons for the fast and distinct response of the Saab 9000. The roll
centre is very low, which prevents body roll.
    The rear axle consists of a light-weight but rigid tube, secured to the body by two
leading and two trailing arms. In addition, it is equipped with a Panhard rod and anti-
roll bar. In a car with rear-wheel drive, the design of the rear axle would have to be
appreciably more complicated to eliminate the undesirable side effects of this type of
design.
    The Panhard rod of the Saab 9000 is fitted at a low level and is secured to the
body at a low point, to eliminate the undesirable and fatiguing lateral swaying
movements of the body. In the same manner as the anti-roll bar, the Panhard rod is
mounted in wellmatched rubber bushes.
    The rear axle suspension consists of conical coil springs of “hemispherical” form
at the top, thereby contributing to the large luggage compartment capacity. The gas
shock absorbers are direct-acting and are secured directly to the axle.
    The arms are long and are mounted in relatively soft rubber bushes. Due to their
length, soft springs with a long travel can be used. The design contributes to
extremely good roadholding and high comfort.
