When work, what the gear shifting rocking arm 1 that is connected with car load drag-line was housed selects shift shaft 3, and gear shifting rocking arm 1 is fixed on the tail end that selects shift shaft 3 by resilient key 2; Selecting shift shaft 3 front ends be fixed with successively change lever 7 and select gear shift cover for seat 4, select gear shift cover for seat 4 to be fixed on and to select on shift shaft 3 by resilient key 30, change lever 7 is fixed on and is selected on shift shaft 3 by resilient key 29; Change lever 7 has shaft sleeve part and is located in opposite directions reverse gear shifting block 703 and the forward gears shifting block 702 of its shaft sleeve part front end, is provided with presynchronization shifting block 701 in the shaft sleeve part tail end of reverse gear shifting block 703 1 sides; By torsion spring 5 activities, reverse gear plectrum 6 is housed selecting between gear shift cover for seat 4 and change lever 7, reverse gear plectrum 6 has is located at dialling angle 601 and being located at the fork shift boss 602 of reverse gear shifting block 703 1 sides of forward gears shifting block 702 1 sides; Select gear shift cover for seat 4 to have torsion spring positioning hole 401 in the front end of fork shift boss 602 1 sides, have spacing hole in the central position of the fork shift boss 602 of reverse gear plectrum 6; The two ends of torsion spring 5 are inserted into respectively to be selected in the torsion spring positioning hole 401 of gear shift cover for seat 4 and the spacing hole of reverse gear plectrum 6.Five grades of shifting blocks 9 have to the extension boss that selects shift shaft 3 sides to stretch out, and have curve bath 902 and the shaft sleeve part phase clamping with change lever 7 by this curve bath 902 on extension boss; Five grades of shifting blocks 9 are provided with in the nearly angle 601 1 side end faces of dialling the shifting block boss 904 rearward stretching out, and shifting block boss 904 is in closely selecting shift shaft 3 one sides to be provided with the guiding surface of dialling angle 601.
Vehicle is in the time preparing reversing, be vehicle in the time of static neutral position state, because reverse idler gear 25 and reverse gear driven tooth 13 are separated from each other, therefore reverse idler gear 25 and reverse gear driven gear 13 do not rotate, meanwhile, five grades of driving tooths 23 and five grades of driven tooth 17 on input shaft 31 are connected with a joggle, because five grades of synchronous gear sleeves 19 are in neutral position state, now, five grades of synchronous gear sleeves 19 and five grades of synchronous gear hubs 20 remain static.When vehicle is stepped on clutch, input shaft 31 still has the rotation time of certain hour, speed changer continues to hang into reverse gear; rocking arm 1 drives and selects shift shaft 3 axial advancement; select the reverse gear shifting block 703 of change lever 7 to move in the fork shift notch 281 of reverse speed shift rod 28, and forward gears shifting block 702 shifts out the shifting block notch 901 of five grades of shifting blocks 9 simultaneously, and now reverse gear plectrum 6 is along with gear selecting operation axial advancement; connect until dial the bottom surface of the shifting block boss 904 of angle 601 and five grades of shifting blocks 9, as schematic diagram 5.
Next, rocking arm 1 drives and selects shift shaft 3 to clockwise rotate, selecting the reverse gear shifting block 703 of change lever 7 to stir reverse speed shift rod 28 moves down, and by reverse speed fork 26, reverse idler gear 25 is moved downward to reverse gear driven gear 13 and reverse driving gear 311 and is connected with a joggle, presynchronization shifting block 701 drives reverse gear plectrum 6 to clockwise rotate by promoting fork shift boss 602 simultaneously, making group angle 601 promote shifting block boss 904 moves up, make five grades of wishbone levers 14 rotate and drive 19 towards five grades of driven tooth 17 of five grades of synchronous gear sleeves and five grades of synchronizing tooth rings 18 to move around bearing pin 15, speed changer is equivalent to and has entered five grades of presynchronization operating modes of speed changer, now owing to only having five grades of synchronous gear hubs 20 to be connected with output shaft, vehicle remains static, therefore five grades of synchronous gear sleeves 1 are staticly not rotate, and five grades of driven tooth 17 and five grades of driving tooths 23 are connected with a joggle, therefore five grades of driven tooth 17 are by five grades of driving tooth 23 driven rotary, due to five grades of synchronizing tooth rings 18 and five grades of driven tooth 17 exist relatively rotate poor, under the downward effect of five grades of synchronous gear sleeves 19, five grades of synchronizing tooth rings 18 produce friction until synchronize with the cone positioning part of five grades of driven tooth 17, i.e. five grades of driven tooth 17, five grades of driving tooths 23 and input shaft 31 all stop operating, as shown in Figure 6.
Along with gear shift is proceeded, reverse gear plectrum 6 continues to clockwise rotate, when the shifting block boss 904 that turns to group angle 601 and five grades of shifting blocks 9 departs from, the plane 903 of the fork shift boss 602 of reverse gear plectrum 6 and the extension boss of five grades of shifting blocks 9 connects simultaneously, and promote five grades of shifting blocks 9 and move down, now the gear face Mei Jiao of reverse idler gear 25 and reverse gear driving tooth 311 gear upper-end surfaces start to connect; Each gear all stops operating thus.Continue to clockwise rotate when rocking arm 1 drives reverse gear plectrum 6, five grades of shifting blocks 9 move down under the drive of the fork shift boss 602 of reverse gear plectrum 6, make five grades of wishbone levers 14 drive five grades of synchronous gear sleeves 19 to separate with five grades of synchronizing tooth rings 18; Simultaneously reverse speed shift rod 28 moves down under the reverse gear shifting block 703 that selects change lever 7 drives, and drives reverse idler gear 25 to slip into smoothly with reverse driving gear 311 and reverse gear driven gear 13 by reverse speed fork 26 to be connected with a joggle.Now, driver lets the clutch be slipped, and engine power completes reversing by reverse idler gear 25 and reverse gear driven tooth 13 normal delivery to output shaft, as shown in Figure 7.
After having moveed backward, driver will put in place and get back to neutral, be that rocking arm 1 rotates counterclockwise, under the reverse gear shifting block 703 of reverse gear plectrum 6 drives, the reverse gear driving tooth 311 that reverse speed fork 26 drives reverse idler gear 25 slowly to depart from, elected change lever 7 rotations to the guiding surface of group angle 601 and five grades of shifting block 9 shifting block boss 904 connects and under the twisting force of torsion spring 5, relatively select change lever 7 to twist, until reverse idler gear 25 departs from reverse gear driven tooth 13 completely, get back to neutral, as shown in Figure 8.Finally select change lever 7 to move to neutral position after selecting gear shift 3, select the presynchronization shifting block 701 of change lever 7 to depart from the shifting block boss 904 of five grades of shifting blocks 9, reverse gear plectrum 6 pops into position under the twisting force of torsion spring 5, completes reverse gear and moves back a grade process, as shown in Figure 5.
