Patent ID: 6962356

Claim:
A toe angle adjustment mechanism for a vehicle having a rear cross member, a pair of rear wheels, and a pair of steering knuckles, the mechanism comprising: an electrical linear actuator fixedly connected to the rear cross member; an interconnection arm pivotally connected with one of the steering knuckles, each of the knuckles being rotationally coupled with a corresponding rear wheel; and a control lever, rotationally attached to the rear cross member, for interconnecting the interconnection arm and the electrical linear actuator, wherein the electrical linear actuator selectively projects or retracts the control lever, which in turn is rotated about a rotary axis thereof so as to correspondingly retract or project the interconnection arm for the purpose of an active adjustment of a toe angle of the rear wheels, wherein the electrical linear actuator includes: a housing: an electrical motor attached to an end portion of the housing; a lead screw disposed inside the housing and rotated by the motor; and a nut rod operatively mounted on the lead screw for linear movement therealong in response to a rotation of the lead screw by the electrical motor, wherein the electrical linear actuator further includes a guide, attached to a lower portion of the housing, and a protrusion positioned on the nut rod, the guide having a groove along which the protrusion slides.
