Abstract

A wheel stabilization mechanism includes an actuator configured to be coupled to a vehicle body and a wheel stabilizer configured to be movably coupled to the vehicle body such that the wheel stabilizer is configured to move with respect to a wheel. The actuator is configured to move the wheel stabilizer with respect to the wheel from a disengaged position toward an engaged position in response to a force applied to the vehicle body. In the engaged position, the wheel stabilizer is configured to inhibit at least a portion of the wheel from moving with respect to the vehicle body to minimize movement of the wheel with respect to the vehicle body.

Claims (23)

1. A wheel stabilization mechanism, comprising:

an actuator coupled to a vehicle body;

a wheel stabilizer movably coupled to the vehicle body such that the wheel stabilizer is configured to move with respect to a wheel, wherein the vehicle body includes a frame coupled to the wheel, and the actuator includes a rod movably coupled to the frame;

wherein the actuator is configured to move the wheel stabilizer relative to the wheel from a disengaged position toward an engaged position in response to a force applied to the vehicle body; and

wherein, in the engaged position, the wheel stabilizer is configured to inhibit at least a portion of the wheel from moving relative to the vehicle body to minimize movement of the wheel relative to the vehicle body.

2. The wheel stabilization mechanism of claim 1 , wherein the force is eccentric to a longitudinal axis of the vehicle body and the frame includes a first frame end and a second frame end opposite the first frame end, and wherein the actuator further includes a plate coupled to the rod, the plate being adjacent the first frame end.

3. The wheel stabilization mechanism of claim 2 , wherein the rod is configured to urge the wheel stabilizer to move from the disengaged position toward the engaged position as the rod moves from the first rod position toward the second rod position.

4. The wheel stabilization mechanism of claim 1 , wherein the rod is configured to move relative to the frame from a first rod position toward a second rod position in response to the force applied to the vehicle body.

5. The wheel stabilization mechanism of claim 4 , wherein the wheel stabilizer includes a lever pivotally coupled to the frame.

6. A vehicle comprising:

a vehicle body;

a wheel coupled to the vehicle body, wherein the vehicle body includes a frame configured to be coupled to the wheel;

an actuator coupled to the vehicle body, wherein the actuator includes a rod movably coupled to the frame;

a wheel stabilizer movably coupled to the vehicle body;

wherein the actuator is configured to move the wheel stabilizer with respect to the wheel from a disengaged position and an engaged position in response to a force applied to the vehicle body; and

wherein, in the engaged position, the wheel stabilizer is configured to inhibit at least a portion of the wheel from moving with respect to the vehicle body to minimize movement of the wheel with respect to the vehicle body.

7. The vehicle of claim 6 , wherein the rod is configured to move with respect to the frame from a first rod position toward a second rod position in response to the force applied to the vehicle body.

8. The vehicle of claim 6 , wherein the wheel stabilizer includes a lever pivotally coupled to the frame.

9. A method of controlling a crush mode of a vehicle body structure movable longitudinally and rollingly supported on a tire/wheel rotatable in a longitudinal plane, comprising:

providing said vehicle body structure with a tire/wheel stabilizer actuatable between first and second positions with respect to said tire/wheel; and

actuating, using an actuator, said tire/wheel stabilizer to one of said positions in response to a vehicle impact eccentric to a longitudinal movement of said vehicle body structure;

wherein the vehicle body structure includes a frame coupled to the tire/wheel; and

wherein the actuator includes a rod movably coupled to the frame.
