Such as Fig. 2, Fig. 7 and shown in Figure 6, angle A and B are the maximum angles into shelves, and angle D, C, K are respectively the top grade district of gear selecting, low-grade district and reverse gear district, then are to confirm by gear signboard 49 when selecting required gear.This ecp gear shifting handle mechanism is fixed by mounting plate 48 and car body.
Working principle:
1. advance the shelves action
Select as required gear when advancing grade, when being in neutral position such as gear shifting handle 1, as long as handle pushes away forward from the F direction, shifting block 7 drove the U-shaped seat 20 of gears, switch actuating piece 8 and advanced that grade locking is recessed takes turns 12 and make together circular movement this moment, switching signal is connected this moment depress corresponding sensitive switch runner when switch actuating piece 8 rotates very small angle after, gear signal output.Grade locking is recessed takes turns 12 under return spring 15 effects along with the increase of gear shifting handle 1 angle is advanced, gear shifting handle 1 forward propulsion is also just larger, cross behind grade bearing 13 centers when advancing recessed 12 peaks of taking turns of grade locking, the U-shaped seat 20 of meeting automatic traction gear turns to the maximum angle A of gear shifting handle 1 under the effect of return spring 15, peak on the U-shaped seat 20 of gear is pushed down grade deenergizing switch 42 that makes the return trip empty soon near maximum angle the time simultaneously, grade deenergizing switch signal that makes the return trip empty this moment is connected, after advancing gear selecting shift fork 28 and turning to maximum angle, advance grade bearing 13 and block rapidly the U-shaped seat of gear 20 lateral grooves, on the gear selecting seat 10 advance grade snubber block 4 immediately shelves live in the gear selecting shift fork, advance shelves actions and finish.
2. the shelves that make the return trip empty move:
As long as the past F direction of gear shifting handle 1 neutral position of pulling back, when shifting block 7 drives the U-shaped seat 20 of gears and switch actuating piece 8 and advances that grade locking is recessed takes turns 12 and do together rotation motion, when the U-shaped seat 20 of gear begins to turn round several angle, peak leaves grade deenergizing switch 42 that makes the return trip empty, this moment, switching signal disconnected, send instruction to ECU in advance by this signal, gearbox gear-shift mechanism execution action, along with the increase of angle of revolution is advanced recessed 12 peaks of taking turns of grade locking and is crossed behind grade bearing 13 centers, under the effect of return spring 15, drive the U-shaped seat of gear 20 automatic rotaries to the neutral position of gear shifting handle 1, simultaneously corresponding signaling switch also disconnects, and the shelves action of making the return trip empty is finished.
3: the gear selecting action
Put in place as long as gear shifting handle 1 pulled to D or C or K direction as required during gear selecting, drive 10 rotations of gear selecting seat by gear shifting handle 1, v-notch in rotary course on the gear selecting seat 10, under the effect of rolling bearing 38 return springs 35 and bearing support 36 along with the increasing action power of angle is also increasing, after if gear shifting handle 1 is pulled toward the C direction, 7 of shifting blocks are close toward the left side, utilize the position on the U-shaped seat 20 of gear to come spacing, if gear shifting handle 1 is toward the D direction when stirring then shifting block 7 is close toward the right, utilize the V-type convex on the gear selecting seat 10 to come spacing, when if gear shifting handle 1 needs past K direction to stir, to apply slightly large active force to gear shifting handle 1, rolling bearing 38 convex of must jumping over, the final position also is next spacing by the U-shaped seat of gear 20 location right, if need only according to advancing a grade motion action after the gear selecting action is finished.As long as according to grade motion action of making the return trip empty, gear selecting seat v-notch is under the active force of return spring 35 when the gear selecting district for shifting block 7 when making the return trip empty grade, and self-return is to the room.
