The brief description operation principle:
One) the speed change system course of work:
Be installed in because of hydraulic continuously variable transmission HST on the shell body of transmission case; The direct driven gear engagement of driving gear on the power shaft of its driving, after HST obtained power from diesel engine, the driving gear on the power shaft of its driving just can be regulated the infinitely variable speeds of output from 0～2600r/nim through the speed adjusting lever of HST; So driven gear just can obtain the rotating speed from 0～1300r/nim; And moment of torsion has also increased (as one times), because the driven gear and first gear shaft are splined, so through first gear shaft this rotating speed is passed to duplicate gear again; And free gear is to be connected movingly with first gear shaft; Can not transmit moment of torsion, but the embedding dental formula clutch on the free gear right side is as long as is connected the rotating speed and the moment of torsion that just can obtain its transmission with the embedding dental formula clutch on the duplicate gear left side, and transmission downwards.
Motionless because of directly being with hydraulic continuously variable transmission HST driven caterpillar tracks, mainly be that speed is too fast, moment of torsion is not enough, so must reduce rotating speed with transmission case, increases moment of torsion.When the needs speed change; The driver must pull the secondary gear change hand lever on the bridge on the gear of setting, the connecting rod that is attached thereto of upper end at this moment, and the lower end also links to each other with gear lever seam (outward); And it has been rotated to an angle that designs; Because of gear lever seam (outward) is fixedly connected with gear lever seam (interior), so this angle has also been rotated in gear lever seam (interior) simultaneously in transmission case, its driving lever because of it in rotation embeds in the elongated slot of selector fork; The straight line that has become selector fork through elongated slot that rotatablely moves of driving lever moves; Two claws because of selector fork are installed in the middle chute of duplicate gear again, just and then move as long as selector fork moves duplicate gear, final duplicate gear just by their chain motion positions on a definite gear.
Two) turn to the brake system course of work:
1, turn about: because of two steering hydraulic oil cylinders are installed on the transmission case, outer left seam of its position positive alignment steering clutch lever and the outer backhand welding of steering clutch lever are closed, if grain header need be turned left; As long as the driver pulls steering arm left, at this moment the left-hand rotation travel switch will be depressed in the steering arm bottom, and the coil of this switch connection electromagnetic hydraulic valve makes the left-hand rotation oil circuit unobstructed; Depress the outer left seam of steering clutch lever behind the left-hand rotation cylinder action; Make it drive shift fork deflection, and be installed in the shift fork mounting groove at left shift fork driven wheel middle part because of its two claws during shift fork deflection, be moved to the left so drive this gear again; This gear has broken away from power after moving; Depressed brake clutch again left crawler belt is halted, but the crawler belt on the right still advances, grain header is to turn left fast in the center of circle with left crawler belt just like this.Turn right and the same principle of turning left.
2, brake: when grain header need brake, as long as step on brake pedal, a brake of pedal pulling backguy; The sleeve pipe of this backguy and steel wire rope are connected on the outer left seam of steering clutch lever respectively and the outer backhand welding of steering clutch lever is closed; Backguy one is drawn, and the steering clutch lever of the right and left moves simultaneously, and originally monolateral action causes brake on one side; Both sides action now is exactly the both sides brakes, so grain header has just stopped at the original place.
