Abstract
Transmission shift control apparatus includes a pin extending from a fulcrum ball to prevent rotation of an associated shift lever. Spring loads are applied to the ends of the pin to establish a neutral position for the shiftf lever in a desired shift plane. The springs are trapped in saddles, which are oriented so as to bias the ball into its seat when the spring load is applied.
Claims11
Shift control apparatus comprising a housing defining a seat having at least one slot, a shift lever including a pivot element in said seat and a pin extending through each slot, and biasing means including at least one biasing mechanism, each biasing mechanism including a saddle riding on said pin and extending therefrom with a pair of base portions contiguous to said housing, and resilient means including a pair of springs respectively biasing said base portions toward contact with said housing.
Shift control apparatus comprising a housing, means defining a seat, means defining a pair of laterally spaced slots, a shift lever including a fulcrum loaded into said seat and a pin extending through said slots, said pin having a lateral axis, and a pair of biasing mechanisms, each mechanism including a saddle with an upper portion adapted to ride on said pin, a pair of leg portions extending downwardly therefrom, a pair of longitudinally extending base portions contiguous to said housing, and a pair of springs acting upon said base portions to bias said saddle downwardly toward contact with said housing, said saddles being selectively movable by said pin upwardly away from said housing upon selective pivotal movement of said shift lever in a lateral plane including said lateral axis, and said shift lever being pivotable about said lateral axis in a longitudinal plane without effecting movement of said saddles by said pin.
