Abstract
A gear-change mechanism for a conventional two-range speed-selection transmission comprises a gear-shift lever which is coupled to a shaft in a housing, this shaft carrying a pair of strikers which engage elements connected to the shifting rod. According to the invention, the striker forms a packet with a plurality of check plates disposed between and in front of and behind the striker plates and held on the shaft for axial displacement therewith. The check plates are guided in the housing so that they cannot rotate with the shaft.
Claims4
A gear-change mechanism for a gear-change transmission having a plurality of gear-shifting rods, said mechanism comprising:
- a gear-change housing;
- a main shaft mounted in said housing so as to be angularly and axially displaceable therein;
- a gear-shift lever manually operated and connected to said shaft for displacement in a gear-shifting pattern to selectively actuate said rod;
- a pair of strikers mounted on said shaft and angularly displaceable therewith for selective engagement with elements connected to said rods for shifting gears upon displacement of said lever in said pattern;
- and
- a plurality of check plates nonrotatably connected to said housing but axially shiftable relative to said housing and carried by said shaft in front of, between, and behind said strikers for axial entrainment thereof with said shaft.
