Abstract
Testing apparatus is disclosed for vehicle steering mechanisms and similar devices for applying a controlled force to a test member. A vertically reciprocable platen carries a hydraulic actuator for applying controlled force to a pivotable test member. The hydraulic actuator is reciprocable along a transverse axis and is connected with the test member by a pivotable coupling. A pivotable link is pivotally connected with a stationary frame and with the mounting frame of the actuator. The distance between the two pivot points on the pivotable link is the same as the distance between the pivot axis of the test member and the pivot axis of the coupling whereby the actuator is caused to traverse an arcuate path when the platen is reciprocated and it thereby follows the arcuate path of the pivotal test member.
