ABSTRACT:
A multistage automatic countershaft transmission adapted for mutually independently shifting the first and second phases of the gears of a transmission to thereby effectuate a smooth gear change within a narrower range of speeds. The countershaft transmission gear is provided with a driving gear which is rotatably supported on a hub, connected to the drum of a gear change clutch, and in engagement with an idle gear supported on a countershaft upon which a countershaft wheel is fixed. The hub and the driven gear are firmly connected and rotatably supported on an output shaft. A carrier of shoes of a gear change clutch is fixed to the hub, the shoes being provided with one or more carrier elements and by means of the carrier elements engage a regulating carrier which is fixed to the output shaft and is provided with an engagement edge, a driving edge, and a rest surface. A combined gear starting and an idle gear are freely rotatably supported on the countershaft, the starting gear being in engagement with a starting device. The idle gear forms a part of an over-running clutch; in recesses of the idle gear there are guided idle clutch bodies, extensions of the starting gear, and disengaging studs, which are part of extensions of the starting gear. Spring biased plunger pins constantly urge the idle bodies toward their separating or non-driving position. The shoes of the gear change clutch are axially guided by the regulating carrier, against which guiding surfaces of the carrier element fixed to a shoe rest.
