Length adjuster and clamping mechanism for a steering mechanism
View Patent ↗The steering mechanism includes a center link which extends between opposite longitudinal ends. Each end has a bore with threads which are spaced from the end by an unthreaded portion. A tie rod includes a bore with threads that are spaced form an end of the tie rod by an unthreaded portion. A length adjuster threadedly connects one of the longitudinal ends of the center link with the tie rod. The length adjuster includes threaded sections and an unthreaded middle section. The unthreaded middle section overlaps with the unthreaded portions of the center link and tie rod bores respectively. A first clamp is clamped around the overlapping unthreaded portion of the center link bore and the unthreaded middle section of the length adjuster, and a second clamp is clamped around the overlapping unthreaded portion of the tie rod bore and the unthreaded middle section of the length adjuster.
1. A steering mechanism for a vehicle, comprising:
a center link extending between opposite longitudinal ends, each of said longitudinal ends having a center link bore with female threads that are spaced from said longitudinal ends by center link unthreaded portions;
at least one tie rod with a tie rod end and a tie rod bore with female threads that are spaced from said tie rod end by a tie rod unthreaded portion;
at least one length adjuster including first and second threaded sections with male threads and an unthreaded middle section;
said first threaded section of said length adjuster being threadedly engaged with said center link bore of said center link with said center link unthreaded portion overlapping with said unthreaded middle section of said length adjuster, and said second unthreaded section of said length adjuster being threadedly engaged with said tie rod bore of said tie rod with said tie rod unthreaded portion overlapping with said unthreaded middle section of said length adjuster; and
a first clamp being clamped at least partially about said overlapping center link unthreaded portion and said unthreaded middle section of said length adjuster and a second clamp being clamped at least partially about said overlapping tie rod unthreaded portion and said unthreaded middle section of said length adjuster.
2. The steering mechanism as set forth in claim 1 wherein said at least one tie rod is further defined as a pair of tie rods and wherein said at least one length adjuster is further defined as a pair of length adjusters.
3. The steering mechanism as set forth in claim 1 wherein said first clamp is formed integrally with said center link.
4. The steering mechanism as set forth in claim 1 wherein said second clamp is formed integrally with said tie rod.
5. The steering mechanism as set forth in claim 1 wherein said unthreaded middle section of said center link includes a tool engaging feature for rotating said length adjuster relative to said center link and to said tie rod to selectively separate or bring together said center link and said tie rod.
6. The steering mechanism as set forth in claim 1 wherein said male threads of said threaded first and second sections of said length adjuster extend in opposite rotational directions.
7. The steering mechanism as set forth in claim 6 wherein said female threads of said center link bore and said female threads of said tie rod bore extend in opposite rotational directions.
8. The steering mechanism as set forth in claim 1 wherein said first and second clamps are formed with a clamshell-like construction.
9. A steering mechanism, comprising:
a center link which extends between opposite longitudinal ends, each of said longitudinal ends having a center link bore with threads that are spaced from the respective end by a center link unthreaded portion;
at least one tie rod with a tie rod end having a tie rod bore with threads that are spaced from said tie rod end by tie rod unthreaded section;
a length adjuster threadedly connecting one of said center link bores with said tie rod bore, said length adjuster including threaded sections and an unthreaded middle section;
said unthreaded middle section of said length adjuster overlapping with said unthreaded portions of said center link bore and said tie rod bore; and
a first clamp being clamped around said center link unthreaded section and said unthreaded middle section of said length adjuster, and a second clamp being clamped around said tie rod unthreaded section and said unthreaded middle section of said length adjuster.
10. The steering mechanism as set forth in claim 9 wherein said at least one tie rod is further defined as a pair of tie rods and wherein said at least one length adjuster is further defined as a pair of length adjusters.
11. The steering mechanism as set forth in claim 9 wherein said first clamp is formed integrally with said center link.
12. The steering mechanism as set forth in claim 9 wherein said second clamp is formed integrally with said tie rod.
13. The steering mechanism as set forth in claim 9 wherein said unthreaded middle section of said center link includes a tool engaging feature for rotating said length adjuster relative to said center link and to said tie rod to selectively separate or bring together said center link and said tie rod.
14. The steering mechanism as set forth in claim 9 wherein said threaded sections of said length adjuster have male threads that extend in opposite rotational directions.
15. The steering mechanism as set forth in claim 14 wherein threads of said center link bore and said tie rod bore extend in opposite rotational directions.
