A brake torque loading linkage for vehicle spindle test fixtures permits applying a brake torque load while other loads are being applied, particularly vertical loading, where substantial movement is encountered, without requiring substantial compensation. The brake torque loading actuator is mounted to move with the vertical loading linkage. The reference for the brake torque is thus on the linkage that moves for applying the vertical load and there is no need to compensate for vertical movements of the spindle being tested when applying the brake torque. The linkage utilized comprises a bell crank loading linkage that is used for applying the torque to a spindle and in particular is useful for testing spindles mounted on pivoting swing arm mountings.

A loading linkage for a spindle assembly having a hub and having a braking torque applying means, said spindle assembly being loaded in a plane lying along the axis of the spindle assembly and in a direction perpendicular to such axis, and also being held from rotation at selected times, including a linkage having bell crank means for applying the load in said plane as the bell crank is moved about a first pivot, and means for applying a torque load tending to rotate the hub relative to the axis of said spindle assembly, wherein the improvement comprises the means for applying a torque load to said hub including an actuator movable with the means for applying the load in said plane about substantially the same axis as said first pivot.
