Abstract
A system and method for adjusting the tread width of a vehicle. Each wheel of the vehicle is provided with two actuators: one toe actuator to adjust the toe angle and one steering actuator to steer the wheel. The toe actuators and steering actuators counterpose each another. The vehicle is configured to actuate the toe actuators to simultaneously turn the wheels on opposite sides of the frame in opposite directions relative to one another, and to actuate the steering actuators to simultaneously turn wheels on opposite sides of the frame in the same direction as one another.
Claims20
A turning assembly for a vehicle comprising:
- (a) a frame
- (b) a first journal coupled to the frame;
- (c) a first leg rotatably coupled within the first journal;
- (d) a first wheel coupled to the first leg;
- (e) a first toe actuator coupled to the first leg;
- (f) a first steering actuator coupled to the first leg;
- (g) a second journal coupled to the opposite side of the frame as the first journal;
- (h) a second leg rotatably coupled within the second journal;
- (i) a second wheel coupled to the second leg;
- (j) a second toe actuator coupled to the second leg;
- (k) a second steering actuator coupled to the second leg;
- (l) a toe controller configured to actuate the first toe actuator and the second toe actuator to angle the first wheel relative to the first journal and the second wheel relative to the second journal in opposite directions simultaneously;
- and
- (m) a steering controller configured to actuate the first steering actuator and the second steering actuator to angle the first wheel relative to the first journal and the second wheel relative to the second journal in the same directions simultaneously.
A toe adjustable vehicle comprising:
- (a) a frame;
- (b) a engine coupled to the frame;
