Semi-automatic transmission
This patent describes a semi-automatic mechanical change gear transmission system of the type comprising: a mechanical change gear transmission of the type comprising a transmission housing, an input shaft rotatably supported in the housing and driven by an engine through a nonpositive coupling, an output shaft rotatably supported in the housing and a plurality of selectable ratio gears selectively engageable one at a time to a first transmission element by means of positive, nonsynchronized jaw clutch assemblies for providing a plurality of manually selectable drive ratios between the input and output shafts, each of the jaw clutch assemblies comprising a first jaw clutch member rotatably associated with the first transmission element and a second jaw clutch member rotatably associated with a second transmission element, each of the first jaw clutch members axially moveable relative to the first transmission element; manually operated means for engaging and disengaging the nonpositive coupling; manually operated shifting means for engaging selected ratio gears to and disengaging selected ratio gears from the first transmission element; selection for sensing the identity of the particular ratio gear selected for manual engagement or disengagement from the first transmission element and for providing a signal; first and second rotational speed sensors for sensing the rotational speed of the first and second transmission elements and providing signals; a power synchronizer assembly selectively actuable for selectively varying the rotational speed of the second transmission element and the second jaw clutch members rotatably associated therewith; and a central processing unit semi-automatic mechanical change gear transmission system.
