Abstract
A toe angle adjustment mechanism includes an electrical linear actuator, an interconnection arm, and a control lever, wherein the electrical linear actuator is mounted on a rear cross member of a vehicle having a pair of rear wheels. The interconnection arm, pivotally attached to the rear cross member, pivotally interconnects the electrical linear actuator with the control lever, which is pivotally connected with a steering knuckle rotationally coupled with a corresponding rear wheel. The electrical linear actuator has a housing, a motor, a lead screw rotated by the motor, and a nut rod operatively mounted on the lead screw for linear movement therealong in response to rotation of the lead screw by the motor.

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