Fine adjustment of a MacPherson suspension strut: means for adjusting on the strut and measuring bench

摘要

The suspension strut consists of a shock absorber with a body (2). A rod is surrounded by a spiral spring (4) which fits between a seat on a lower thrust cup (41) fixed to the body. An upper cup is connected to the vehicle bodywork. The lower cup has a regulator to control its position relative to the axis of the spring. A cam (420) is adjusted by rotating it. The cup rests on the cam via a plate and ball bearings (42) to facilitate its movement. It has index markings to indicate its position relative to the shock absorber body.
