Shift mechanism for automotive transmission

Abstract

In a shift mechanism for an automotive transmission of the type wherein the lower end of a shift lever is coupled through a control rod to a control shaft of the automotive transmission, means for pivotally supporting the shift lever for the select and shift operations is mounted on a parallelogram double rocker linkage consisting of a pair of parallel rockers the upper ends of which are pivoted to a chassis and a coupler the both ends of which are pivoted to said pair of parallel rockers in such a way that the line connecting between the pivotal points of the coupler may be in parallel with the line connecting the upper pivotal points of the pair of parallel rockers and that the parallelogram double rocker linkage pivots about said upper pivotal points of the pair of parallel rockers in a vertical plane in parallel with the axis of the control rod; and the lower end of one of the pair of parallel rockers is pivoted to one end of a support rod which extends in parallel with the control rod and which has its the other end pivoted to the automotive transmission housing, whereby even when the displacement of the automotive transmission with respect to the chassis occurs, the knob at the top of the shift lever may be maintained substantially stationary.
