Adjustable aerodynamic splitter
View Patent ↗An adjustable aerodynamic splitter for a motor vehicle having a rearward flexible segment for attachment to the vehicle body and a forward more rigid segment, wherein the forward segment's leading edge is arranged for selectively attaching thereto an extension strip of a desired width, and at least one pair of adjustable length linkages attaching the splitter to the vehicle body near the leading edge, spaced symmetrically about the vehicle centerline, and arranged to raise or lower the leading edge in response to adjustment of the linkages' length.
1. A splitter for mounting generally symmetrically about a motor vehicle centerline on the forward underside portion of the vehicle body for directing the incoming airflow when the vehicle is in motion, comprising:
a body panel having i) a rearward flexible segment for attachment to the vehicle body, and ii) a forward segment more rigid than the rearward segment and having a leading edge contoured to define an elongated recess spaced symmetrically with respect to the body panel centerline and an extended section on either side of the recess, the leading edge arranged for selectively attaching thereto an extension strip of a desired width; and
at least two adjustable length linkages spaced symmetrically with respect to the panel centerline, each having a first end attached to the vehicle body and a second end attached to the body panel near the leading edge, and arranged to raise or lower the leading edge in response to adjustment of the length of the linkage.
2. The splitter of claim 1 further comprising an extension strip and wherein the leading edge includes an offset band for selectively attaching thereto the extension strip by a lap joint.
3. The splitter of claim 2 wherein the extension strip comprises a first part attached to the recess, and second and third parts attached to the extended sections.
4. The splitter of claim 2 wherein the extension strip comprises energy absorbing and compression resisting material.
5. The splitter of claim 2 wherein the extension strip extends below the bottom surface of the leading edge, thereby forming a step for abrasion capacity and for limiting lift on the forward portion of the vehicle-body.
6. The splitter of claim 1 wherein the body panel is a multi-layer laminate.
7. The splitter of claim 6 further comprising an extension strip and wherein an upper layer of the multi-layer laminate overlaps a lower layer at the leading edge thereby forming an offset band for selectively attaching thereto the extension strip by a lap joint.
8. The splitter of claim 1 wherein the body panel is comprised of carbon fiber.
9. The splitter of claim 1 wherein the rearward flexible segment is shaped according to an empirically determined contour when viewed from the front of the vehicle to provide laminar airflow along the forward underside portion of the vehicle by diffusing airflow and reducing underside air pressure.
10. The splitter of claim 1 wherein the at least two adjustable length linkages each comprise a threaded length connected by a turnbuckle.
11. A motor vehicle body having a splitter mounted generally symmetrically about the vehicle body centerline on the forward underside portion of the vehicle body for directing the incoming airflow when the vehicle is in motion, the splitter comprising:
a body panel having i) a rearward flexible segment for attachment to the vehicle body, and ii) a forward segment more rigid than the rearward segment and having a leading edge contoured to define an elongated recess spaced symmetrically about the vehicle centerline and an extended section on either side of the recess, the reading edge arranged for selectively attaching thereto an extension strip of a desired width; and
at least two adjustable length linkages spaced symmetrically with respect to the panel centerline, each having a first end attached to the vehicle body and a second end attached to the body panel near the leading edge, and arranged to raise or lower the leading edge in response to adjustment of the length of the linkage.
12. The motor vehicle body of claim 11 further comprising an extension strip and wherein the leading edge includes an offset band for selectively attaching thereto the extension strip by a lap joint.
13. The motor vehicle body of claim 12 wherein the extension strip comprises a first part attached to the recess, and second and third parts attached to the extended sections.
14. The motor vehicle body of claim 12 wherein the extension strip comprises energy absorbing and compression resisting material.
15. The motor vehicle body of claim 12 wherein the extension strip extends below the bottom surface of the leading edge, thereby forming a step for abrasion capacity and for limiting lift on the forward portion of the vehicle body.
16. The motor vehicle body of claim 11 wherein the body panel is a multi-layer laminate.
17. The motor vehicle body of claim 16 further comprising an extension strip and wherein an upper layer of the multi-layer laminate overlaps a lower layer at the leading edge thereby forming an offset band for selectively attaching thereto the extension strip by a lap joint.
18. The motor vehicle body of claim 11 wherein the body panel is comprised of carbon fiber.
19. The motor vehicle body of claim 11 wherein the rearward flexible segment is shaped according to an empirically determined contour when viewed from the front of the vehicle to provide laminar airflow along the forward underside portion of the vehicle by diffusing airflow and reducing underside air pressure.
20. The motor vehicle body of claim 11 wherein the at least two adjustable length linkages each comprise a threaded length connected by a turnbuckle.
