Embodiment
Consult Fig. 1, Fig. 2, Fig. 3, high and low gear operating mechanism is comprised of secondary gear shift fork pivoted arm 6, secondary speed changing flexible shaft pivoted arm 7, secondary speed change pivoted arm 21, secondary gear shift fork 22.Secondary gear shift fork 22 is arranged in gearbox.Insert in the fork pockets of secondary gear shift fork 22 secondary speed change pivoted arm 21 one end, and its square toes partly, through the mounting hole of gear shift cover 5, are connected with the square hole of secondary gear shift fork pivoted arm 6, then use nut check.When pushing away, drawing secondary speed changing flexible shaft pivoted arm 7, thereby can make secondary gear shift fork pivoted arm 6 drive secondary speed change pivoted arm 21 rotations to promote secondary gear shift fork 22 displacements, realize the switching of high and low gear.
Main selector gear is formed the also switching of main transformer speed gear by main transformer position flexible axle pivoted arm 8, return spring 9, main transformer position pull bar 10, main shift lever 11, guide sleeve 12, main transformer gear flexible axle pivoted arm 13, bearing pin 14, connecting bolt 15, fixed plate 16, limiting board 17, main shift lever seat 18, position-limited lever 23.Main shift lever seat 18 is arranged in the mounting hole of gear shift cover 5, with bolt, fixes.Main shift lever 11 is through the endoporus of main shift lever seat 18 and the endoporus of guide sleeve 12, is connected and uses nut check, the bulb end of main shift lever 11 to insert I in gearbox-reverse gear fork 19 or II-III is kept off in the fork pockets of fork 20 with connecting bolt 15.Axially with between guide sleeve 12 being connected by slide rail of main shift lever 11.Slide rail on main shift lever 11 has 2 at least, and the chute on the guide sleeve 12 matching with slide rail on main shift lever 11 also has 2 at least.Slide rail on main shift lever 11 is groove or tongue, and the chute on the guide sleeve 12 matching with slide rail on main shift lever 11 is tongue or groove.Bearing pin 14 passes the circular hole of connecting bolt 15, and with main transformer position pull bar 10, is connected to each other between main transformer position flexible axle pivoted arm 8.Circular hole on main transformer position flexible axle pivoted arm 8 is connected with the bulb of main transformer position flexible axle 1 and uses nut check.Main transformer gear flexible axle pivoted arm 13 is welded on guide sleeve 12, and the bulb that the circular hole on main transformer gear flexible axle pivoted arm 13 and main transformer keep off flexible axle 3 is connected and uses nut check.Limiting board 17 is welded on main shift lever seat 18 belows.Fixed plate 16 is arranged on limiting board 17 belows and fixes with bolt, can prevent that guide sleeve 12 from moving axially along main shift lever 11.Position-limited lever 23 is fixed on main shift lever 11 and uses nut check.Return spring 9 is installed on main shift lever 11, improves control stability.
Its nut check carrying of secondary speed changing flexible shaft 2 use is in the corresponding aperture of flexible shaft bracket 4, its movable end one end is connected with the circular hole of secondary speed changing flexible shaft pivoted arm 7 and uses nut check, the other end puts in operator cabin and is connected with secondary shift, when pushing away, while drawing secondary shift, thereby secondary speed changing flexible shaft 2 drives secondary speed changing flexible shaft pivoted arm 7 and secondary gear shift fork pivoted arm 6 swing and make secondary speed change pivoted arm 21 rotations promote secondary gear shift fork 22 displacements, realizes the switching of high and low gear.
Its nut check carrying of flexible axle 1 use of main transformer position is in the corresponding aperture of flexible shaft bracket seam 4, and its movable end one end is connected with the circular hole of main transformer position flexible axle pivoted arm 8 and uses nut check, the other end to put in operator cabin and is connected with the block selecting arm on main shift; Its nut check carrying of main transformer gear flexible axle 3 use is in the corresponding aperture of flexible shaft bracket 4, its movable end one end is connected and uses nut check, the other end to put in operator cabin with the main transformer gear flexible axle pivoted arm circular hole of guide sleeve 12 and is connected with the arm of putting into gear on main shift.
Because the block selecting arm on main shift and the unique design of arm of putting into gear can make when the main shift of left and right swing, main transformer position flexible axle 1 works and main transformer gear flexible axle 3 is inoperative, during the main shift of forward and backward push-and-pull, main transformer gear flexible axle 3 works and main transformer position flexible axle 1 is inoperative.During operation, first swinging to the left or to the right main shift works main transformer position flexible axle 1 to drive main transformer position flexible axle pivoted arm 8 and main transformer position pull bar 10 swing and drive main shift lever 11 to move vertically, make it in the I-switching between fork 19 and II-III gear fork 20 of reversing gear, after switching puts in place immediately before, rear push-and-pull main transformer speed operating handle works main transformer gear flexible axle 3 and drives 13 swings of main transformer gear flexible axle pivoted arm, thereby drive guide sleeve 12 and main shift lever 11 to swing, can hang up I, II, III and reversing gear, mix again aforementioned height, low gear, can realize (3+1) * 2 kind of gear selects, 6 forward gears and 2 are reversed gear.
