MacPherson strut

E; abcde
DEF AN 115
Independent wheel suspension element in which a shock absorber is fitted inside a telescopic tube called a suspension strut, and a helical spring mounted at the upper end of this tube, which is connected to the lower suspension arm, while the upper end is bolted on the body frame. (R)|cd|
CONT AN 120
The construction of the MacPherson strut is typical. The hub carrier is attached (by welding) to the outer tubular member of the strut. At the base of this member is a sealed ball joint mounted in the extremity of the lower transverse link. Under maximum bump and rebound, the strut moves through an angle of 2.5° and the required compliance is given by a hollow rubber bush where the strut is attached to the body. This rubber bush is bonded to a pressed steel housing which contains a ball thrust bearing. Since the strut also acts as a telescopic damper, the inner rod carries a damper piston at its lower end. At the upper end of this rod a threaded portion of reduced diameter is locked to the rubber mounting and is located by the inner race of the ball bearing. This thrust bearing allows free angular movement of the tubular strut as the wheel is steered. |f|
