Abstract
A remote control gear shift linkage system for a manual transmission comprises a manually operable control lever, a control rod connected between the control lever and the transmission for transmitting a movement of the control lever to the transmission to effect a gear shift, and a support rod supported on a vehicle body for supporting the control lever. In order to avoid unwanted influences of a resonance of the remote control linkage, a concentrated mass member is fastened to a portion of the support rod. The concentrated mass member may take the form of a sleeve fitted over the support rod or a solid bar fitted into the bore of the hollow support rod.
Claims4
A remote control gear shift linkage system for a manual type vehicular transmission, comprising:
- a manually operable control lever having upper and lower ends,
- a support member for supporting said control lever at an intermediate portion thereof between said upper and lower ends so that said control lever is swingable at said intermediate portion,
- means for resiliently mounting said support member to a vehicle body,
- a control rod connected between said lower end of said control lever and the transmission, for transmitting movement of said control lever to the transmission to effect a gear change of the transmission, a support rod
- connected between said support member and a case of the transmission, and
- mass means fastened to a portion of said support rod for altering the resonant frequency of said support rod.
