摘要： A loading assembly used in a vehicle spindle test fixture includes a wheel adapter housing that is mountable to a vehicle spindle. A pair of vertical struts are provided. Each vertical strut is joined to the wheel adapter housing at spaced-apart first pivot connections. A bell crank is coupled to each end of the vertical struts at spaced-apart second pivot connections. An actuator is pivotally coupled to the bell crank at a third pivot connection. The location of the second pivot connections relative to the third pivot connection approximates the location of the first pivot connections relative to the spindle axis.

摘要： A loading assembly used in a vehicle spindle text fixture to apply a lateral force parallel to a spindle axis of a vehicle spindle includes a support frame and a wheel adapter housing mountable to the vehicle spindle. A pair of vertical struts are pivotally joined to the wheel adapter housing. A first actuator is operably coupled to the vertical struts to apply a force along a vertical axis substantially perpendicular to the spindle axis and substantially perpendicular to a longitudinal axis of the vehicle. A pair of lateral struts are provided. Each lateral strut is pivotally joined to one of the vertical struts. A second actuator is operably coupled to the lateral struts to apply a lateral force.

摘要： A loading assembly for a vehicle spindle test fixture includes a belt crank that pivots on a first axis to differentially displace two vertical struts which are attached to a wheel adapter housing in order to apply a braking moment to the vehicle spindle. A lever pivotally supported about a second axis is pivotally joined to the bell crank and is used to displace the bell crank, the vertical struts and the wheel adapter housing to apply a vertical force. A control link controls rotation of the bell crank about the first axis and is pivotally joined to the bell crank about a third axis. A second lever is pivotally supported for movement about the second axis and is pivotally joined to an end of the control link about a fourth axis. When a trailing arm suspension is to be tested, the bell crank, the first lever, the control link and the second lever are arranged to form a non-parallelogram linkage in order to induce a brake axis rotation when a vertical displacement is applied.

摘要： A loading assembly used to apply selected forces and moments to a vehicle spindle includes a wheel adapter housing mounted to the vehicle spindle. In a first embodiment, the loading assembly reduces crosstalk between application of lateral forces and unintended braking moments, and lateral forces and unintended longitudinal forces. In a second embodiment, a second loading assembly is adjustable so that braking moments are induced when a vertical force is applied when the loading assembly is used on trailing arm suspensions.
