As shown in Figure 6, arrange to tell about the R shelves latch functions of 5/R in the present embodiment with the gear of 135/24R, wherein as shown in Figure 1, initial position is 3/4 file location; In the time that gear-changing and selecting shifting block 6 is moved to the left, selecting gear shift guide block 4 to turn left is gear selecting to 1/2 grade, and now the second confined planes 18, because being subject to the effect of handling the first position-limiting action face 13 that covers 2 to select gear shift without affecting on 1/2 grade and 3/4, now specifically selects gear shift and reverse gear locking process to be described below to 5/R shelves:
1) five reverse gears select gearshift procedure:
Gear selecting process: gear-changing and selecting shifting block 6 is selecting the segment distance that moves right under shift shaft 1 effect, and the gear shift guide block 4 that selects that makes to be arranged on declutch shift shaft 3 turns right after several angle around declutch shift shaft 3, completes five reverse gear gear selectings;
Gearshift procedure: in the time completing five reverse gear gear selectings, gear-changing and selecting shifting block 6 select shift shaft 1 under effect around shifting axle 1 several angle that rotates backward, make to select gear shift guide block 4 to drive declutch shift shaft 3 and act on gear shift fork and move backward, now select gear shift guide block 4 to act on the first confined planes 16 makes reverse gear lock banking stop 10 simultaneously along selecting shift shaft 1 and screw rod 8 double sided slider bars to move axially a segment distance simultaneously, return unit 9 is in compressive state, and the second position-limiting action face 21 contacts with the first confined planes 16 all the time, can not form locking effect, now complete neutral gear and enter five grades of N-5 gear shift; Otherwise when gear-changing and selecting shifting block 6 rotates forward, the second position-limiting action face 21 also contacts all the time with the first confined planes 16, does not form locking effect, now complete neutral gear and enter reverse gear N-R gear shift.
2) double sided slider bar anti-rotating function is realized:
As Figure 1 and Figure 4, bar pilot hole 19 and axle pilot hole 20 empty sets are being selected on the cylindrical of shift shaft 1 and screw rod 8, make:
1. in the time entering and move back 5/R gear selecting, reverse gear lock banking stop 10 can move axially by free travel double sided slider bar;
2. in the time directly entering reverse gear for five grades, can play the degrees of freedom of restriction reverse gear lock banking stop 10 around axial rotation, concrete N-5-N-locking R process: in the time completing N-5 grade, the first confined planes 16 no longer contacts with the second position-limiting action face 21, now reverse gear lock banking stop 10 should not selected the restriction of gear shift guide block 4, under the elastic force effect of return unit 9, reverse gear lock banking stop 10 is axially repositioned to initial position along double sided slider bar.Now if desired directly hang hot reverse gear from five grades, select the shift shaft 1 must be around its axis counterrotating, form and select gear shift guide block 4 to move forward vertically trend, in the time moving to neutral position, locking acting surface 22 can contact with the locking face 17 on reverse gear lock banking stop 10.Reverse gear lock banking stop 10, because being selected the double sided slider bar of shift shaft 1, screw rod 8 to limit it around the degrees of freedom of selecting shift shaft 1 to rotate, now just can be limited in neutral position by gear shift fork, and can only lower category and enter five grades of actions.So, just, complete reverse gear locking process.
