The invention relates to an association model testing device capable of adjusting wheel orientation angles and side slip distances, belonging to research equipment for building a relation database of the automotive wheel side slip distance and the automotive wheel orientation angles. The association model testing device comprises a toe regulating mechanism (A), a side slip distance testing device (B), a wheel clamping assembly (C), a wheel force application mechanism (D) and a camber angle regulating mechanism (E), wherein, the wheel orientation angle regulating device is composed of the camber angle regulating mechanism and the toe regulating mechanism. The invention mainly aims to find corresponding wheel side slip distance at the matching relations of different orientation angles and build the relation database of the wheel orientation angles and the wheel side slip distances through regulating the wheel orientation angles ( the wheel camber angle and the toe). The database can realize rapid dynamic survey of the wheel orientation angles on an automotive detection line and the accurate adjustment of the wheel orientation angles, thus effectively eliminating wheel side slip phenomenon caused by out of alignment of a wheel orientation parameter.
