Chapman strut

Encyclopedia : C : CH : CHA : Chapman strut

A front-left McPherson strut, similar to a Chapman strut on the rear of a vehicle with no drive axle, (lateral locating arm to adjust rear wheel toe in light blue).

A Chapman strut is an automobile suspension device. Being a strut, it is designed to act as both a shock absorber (with an integrated coil spring) and a wheel location device. That is, it is designed to resist lateral forces. Chapman struts are the term for such a device when used on rear wheels, while the very similar MacPherson strut is used in front. (See MacPherson strut for more information.)

The Chapman strut was named after Colin Chapman, the famed Lotus engineer, and was first used on the Lotus 12.
