ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates generally to wing mechanisms, air spoilers and air foils for a motor vehicle and more particularly to a front wing mechanism that may be selectively positioned from within the vehicle cockpit.
2. Discussion
Modernly, various types of front spoilers or wing mechanisms for motor vehicles have been proposed in order to improve the high-speed stability of vehicles. Some of the front wing mechanisms are of a fixed type in which a spoiler fin or wing member is unmovably mounted to a forward portion of the vehicle. However, front wing mechanisms of this type are known to negatively affect the performance of the vehicle when the vehicle is operated at relative low speeds.
SUMMARY OF THE INVENTION
It is one object of the present invention to provide a front wing mechanism with a wing member that may be selectively moved to vary the magnitude of a downwardly directed force produced by the wing member.
It is another object of the present invention to provide a front wing mechanism with a drive assembly for adjusting the rotational position of a wing member that is relatively compact and actuatable from within the vehicle cockpit.
In one form, the present invention provides a wing mechanism for selectively exerting a downwardly directed force to a vehicle is provided. The wing mechanism includes a wing member, an axle, a pair of pivot arms and a drive assembly. The wing member is adapted to be pivotably coupled to the vehicle body about a first axis. The axle is adapted to be pivotably coupled to the vehicle body about a second axis parallel to the first axis. Each of the pivot arms has a first end and a second end wherein the first end of each pivot arm is pivotably coupled to the wing member and the second end of each pivot arm is coupled for rotation with the axle. The drive assembly is coupled to the axle and operable for selectively positioning the axle in a rotational position to adjust an angular position of the wing structure.
Additional advantages and features of the present invention will become apparent from the subsequent description and the appended claims, taken in conjunction with the accompanying drawings.
