Abstract
Two transmission shift levers are pivotally movable, one universally and the other about a single axis, by respective control members operative thereon through concentric shafts, the shaft associated with the universally pivotable lever being axially slidable relative to the shaft associated with the other lever in response to translational movement of its control member.
Claims12
A control apparatus for transmissions and the like comprising a shift actuator lever universally pivotable about a fixed point, a movable control shaft having a longitudinal axis and a connection, said connection including a first element fixed to said shaft and a second element connected to said first element for translational movement with said first element and pivotal movement relative to said first element about an axis parallel to said shaft axis, said lever being secured to said second element for universal pivotal movement about a fixed point on said second element in response to said translational and pivotal movements of said second element.
Control apparatus for transmissions comprising:
- a first shift actuating member movable in a first shifting plane between at least one active position and neutral position;
- a second shift actuating member movable in a second shifting plane between at least one active position and neutral position, and a third shifting plane between at least one active position and neutral position;
- first control lever selectively movable in a first control plane, a second control lever selectively movable in a neutral control plane intersected by second and third control planes, said second control lever being selectively movable in said second and third control planes when moved to the respective intersections thereof with said neutral control plane;
- and shift mechanism interconnected with said control levers and shifting members operable to (1) cause said first shift actuating member to move in said first shifting plane in response to corresponding movement of said first control lever in said first control plane, (2) cause said second shift actuating member to move in said second shifting plane in response to corresponding movement of said second control lever in said second control plane with said first shift actuating member located at any selected position in said first shifting plane, and (3) cause said second shift actuating member to move in said third control plane in response to corresponding movement of said second control lever in said third control plane with said first shift actuating member located at any desired position in said first shifting plane.
