Abstract

Motor vehicle dampers are checked without the need for removing them from the vehicle. This is performed by recording the oscillation of the body when released from the fully extended height of the damper. This recording is compared with that from a new damper. The damper (1) is tested by raising (3) the bodywork (2) fully to extend each unit. A cable (11) is attached (16) to the body and passes over a pulley (12) to a return spring in a chart recorder (4). Action of the pulley is geared down (13, 14) to drive the stylus (15) on a chart (18). Recording is synchronised (6) to start the chart motor (17) when the body lift (3) is rapidly lowered.
