Friction disk shock absorbers or André Hartford dampers were an early form of shock absorber or damper used for car suspension. They were commonly used in the 1930s but were considered obsolete post-war. Compared to modern shock absorbers friction dampers only provided limited shock absorption but … See more The friction disk pattern was invented by Truffault, before 1900. These used oiled leather friction surfaces between bronze disks compressed by adjustable conical springs, with the disk pack floating between arms to … See more Motorcycles of the same period, through to the 1950s, that used girder forks also used friction disk shock absorbers.

André Hartford pattern See more The damping rate for frictional dampers has less than ideal behaviour for car suspension. An ideal suspension would offer more damping to greater suspension forces, with less … See more Hartford shock absorbers were also used within the manual lever frames of some UK signalboxes.
