FIELD: automotive industry.
SUBSTANCE: according to proposed method, external force is applied to rear side of aerodynamic surface to shift it from idling position when it is placed o surface of body or cab, into operating position in which said surface is arranged at angle to surface with which it is turnably connected, and back. External force is applied to rear side of aerodynamic surface at angle to said surface from point found on surface of body or cab of vehicle at a distance from aerodynamic surface from side of one side edge of said surface in direction of point found on rear side of aerodynamic surface at opposite side edge or between upper and lower edges of said surface from side of opposite side edge. External force is applied with simultaneous displacement of point of force application of rear side of aerodynamic surface along trajectory from lower edge from side of opposite side edge or opposite edge or zone of lower angle at this edge in direction to upper of aerodynamic surface. Regulator of aerodynamic stabilizer contains tie-rod connected by one end with drive and hinge-coupled by other end with rear side of aerodynamic surface. Tie-rod is made in form of bellcrank whose support point is located on surface of body or cab of vehicle at a distance from one side edge of aerodynamic surface from rear side. Arm of bellcrank hinge-connected with aerodynamic surface is arranged at angle to rear aerodynamic surface in direction towards its opposite side edge, and hinge joint on said arm of bellcrank is installed for travel in guides on rear side in direction from lower edge from side of opposite side edge or opposite edge, or zone of lower angle at this edge in direction to upper edge of aerodynamic surface.
EFFECT: improved of selection of required angular position of aerodynamic surface.
