TECHNICAL DESCRIPTION
FRONT END AND STEERING
Front end
The car has independent front suspension.
The front suspension units are mounted
on a strong box member. The member is
bolted firmly to the front section of the
body. The front wheels are journalled in
tapered roller bearings. The front springs
consist of coil springs in which telescopic
shock absorbers are fitted. The car is
provided with stabilizers secured to the
l ower control arms and to the body.
Mechanical steering
Certain variants of the Volvo 164 are fitted
with mechanical steering.
The steering is of the cam-and-roller type.
Movements of the steering wheel are
transmitted via the worm on the steering
column to the ball nut for the pitman shaft,
which in turn operates the wheels through
a linkage system.
Servo steering
The servo cylinder and guide valves are
built into the cam-and-roller type steer-
i ng gear. When the steering wheel is
turned, the guide valves direct the pres-
sure oil from the servo pump to one of
the sides of the piston in the servo cylin-
der. The resultant pressure on the piston
side affected assists in turning the steer-
i ng wheel.
