Detailed description of the invention
Referring to Fig. 1, Fig. 2, Fig. 3, the present invention includes shift fork axle 1, shift fork shaft lock block 2, steel-ball limiting lock 3, steel-ball limiting lock fixed plate 5 and shift fork axle location-plate 4, described shift fork axle 1 quantity is mated with transmission gear figure place, all shift fork axles 1 are in parallel arrangement state, and limit its reciprocating motion track by shift fork axle location-plate 4, each shift fork axle 1 is respectively provided with shift fork shaft lock block 2, described shift fork shaft lock block 2 is equipped with steel-ball limiting lock 3, described steel-ball limiting lock 3 is assembled with shift fork axle location-plate 4 by steel-ball limiting lock fixed plate 5, described shift fork axle location-plate 4 is fixed on case of transmission.
Referring to Fig. 5, Fig. 6, Fig. 7, the hollow circular-tube structure that steel-ball limiting lock 3 is closed at both ends of the present invention, its inner chamber is straight line or easy curve type passage, can free rolling steel ball 3-1 equipped with one group in described passage, described steel ball 3-1 diameter d matches with channel internal diameter D, steel ball 3-1 arranges along channel-length direction, at length direction preset clearance a between steel ball 3-1 and passage, arranging one group of through hole 3-2 identical with the shift fork number of axle on hollow circular-tube tube wall, the orifice position of described through hole 3-2 is corresponding with shift fork shaft lock block 2.
Referring to Fig. 4, the shift fork shaft lock block 2 of the present invention is open rectangular channel structure, is provided with plate 2-1 the most positioned opposite at its opening part, and described plate 2-1 end is cone angle structure.
Referring to Fig. 5, Fig. 7, the plate 2-1 width b of the present invention locks through hole 3-2 aperture width c, i.e. b ＜ c less than steel-ball limiting；The steel-ball limiting of the present invention locks through hole 3-2 aperture width c less than steel ball 3-1 diameter d, i.e. c ＜ d；At length direction preset clearance a equal to plate 2-1 width b, i.e. a=b between steel ball 3-1 and the passage of the present invention.
Referring to Fig. 8, the present invention is when a certain gear hung by variator, shift fork shaft lock block 2 moves up or down along with shift fork axle 1 fixed thereto, lock the through hole 3-2 aperture arranged 3 hollow circular-tube tube walls from steel-ball limiting and insert in steel-ball limiting lock inner chamber, shift fork shaft lock block 2 promotes steel ball 3-1 to move by the cone angle structure of plate 2-1, the through hole of remaining gear is blocked by steel ball 3-1, the plate 2-1 being now inserted into due to scroll space occupies, thus cause steel ball 3-1 to contact with each other and cannot move, remaining shift fork shaft lock block 2 is caused to be stopped by steel ball 3-1 and cannot move up and down, therefore after variator is linked into this gear, locked other shift fork shaft lock block 2 locking by steel-ball limiting, achieve the interlock function between different gear.
