Description
Technical field
The utility model, in particular to a kind of six gear gear shifting mechanism of mechanical gearboxes, belongs to the technical field of transmission design.
Background technique
At present, the gearshift of mechanical transmission adopts following form usually: for six gear manual transmissions, on interlock mode, at present conventional is that interlock recess on interlocking steel ball, interlocking plunger and fork shaft is worked in coordination the structure of locking, and the amount of parts that this mode is applied is more, and structure is relatively complicated, and reliability is not high, majority is without any process in gearshift feel, and shift feel is not obvious, and shifting comfort is poor.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of six gear gear shifting mechanism of mechanical gearboxes, and its structure is simple, easy to process, and amount of parts is few, and equipment adjustment is easy, also reduces cost simultaneously.In shift feel, use integrated self-locking spring assembly, effectively increase gearshift feel, make gear more clear and definite, add shifting comfort, integrated form locating stud is convenient to modularized production and exchange simultaneously.
The technical solution of the utility model is achieved in that a kind of six gear gear shifting mechanism of mechanical gearboxes, the board-like mutual interlocking gear of limiting board and interlocking block pressing plate composition is fixed in transmission upper cover respective aperture by hexagon head bolt, and gear shifting pulling head is fixed on the shifting shaft that mates with it; It is characterized in that: block selecting damping spring assembly is fixed on the board-like mutual interlocking gear on upper cover housing by screw thread, gear shifting pulling head has groove, assemble damping spring, steel ball seat and steel ball successively in the self-locking spring shell of block selecting damping spring assembly, wherein steel ball rolls with the groove that gear shifting pulling head has and coordinates.
Good effect of the present utility model is on interlock mode, adopt single interlock board to realize interlocking between each gear, and structure is simple, easy to process, easy mounting and adjusting and maintenance.In gearshift feel, adopt integrated self-locking spring assembly, the convenient shift of transmission that increases is felt, improves shift of transmission travelling comfort.Be conducive to generalization raising and transmission moduleization production.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1,2,3, 4, a kind of six gear gear shifting mechanism of mechanical gearboxes, the board-like mutual interlocking gear that limiting board 11 and interlocking block pressing plate 14 form is fixed in transmission upper cover respective aperture by hexagon head bolt 2, and gear shifting pulling head 10 is fixed on the shifting shaft that mates with it; It is characterized in that: block selecting damping spring assembly 12 is fixed on the board-like mutual interlocking gear on upper cover housing by screw thread, gear shifting pulling head 10 has groove, assemble damping spring 12-2, steel ball seat 12-3 and steel ball 12-4 successively in the self-locking spring shell 12-1 of block selecting damping spring assembly 12, wherein steel ball 12-4 rolls with the groove that gear shifting pulling head 10 has and coordinates.
As shown in Figure 1, 2, gear shift fork shaft-three speed and four-speed 3, gear shift fork shaft-the first speed and the second speed 5, gear shift fork shaft-fall speed 6 and gear shift fork shaft-five speed and the 6th speed 17 are fixed in transmission upper cover respective aperture, and can slide axially; Limiting board 11 and interlocking block pressing plate 14 are fixed in transmission upper cover respective aperture by hexagon head bolt 2; Locking plate A1 and locking plate B15 can prevent hexagon head bolt 2 from loosening; Gear shifting pulling head 10 is fixed on the shifting shaft that mates with it, and can slide axially; It can be also that block selecting increases sensation by the convex on gear shifting pulling head 10 that block selecting damping spring assembly 12 is fixed in upper cover respective aperture; Self-locking spring 16 and steel ball are fixed in upper cover respective aperture, and for preventing off-gear and increasing shift feel; Shifting fork-five speed and the 6th speed 8 play commutation effect, be fixed on cover by reversing shaft-five speed and the 6th speed 19, hexagonal flute profile flat nut 20, cotter pin 21 and pad-communtation arm 22.Shifting fork-the first speed and the second speed 4, shifting fork-fall speed 7, shift rug-five speed and the 6th speed 13 and shifting fork-three speed and four-speed 18 be separately fixed at gear shift fork shaft-the first speed and the second speed 5, gear shift fork shaft-fall speed 6 and gear shift fork shaft-five speed and the 6th speed 17 on; Interlocking block 9 is fixed on interlocking block pressing plate 14, and can slide on the track of interlocking block pressing plate 14, plays the effect preventing from being simultaneously linked into two gears.As putting of being formed of figure interlocking block 9, limiting board 11 and interlocking block pressing plate 14 is only linked into two structures of keeping off simultaneously, two is be embodied on block selecting damping structure that gear shifting pulling head 10 and block selecting damping spring assembly 12 form.
Action when reversing gear hung by speed changer: external agency by gear shifting pulling head 10 to shift rug-five speed in speed 6 of gear shift fork shaft-fall and the 13 mouthfuls of motions of the 6th speed, gear shifting pulling head 10 drives interlocking block 9 to move to reverse gear gear mouth place, convex structure in movement process on gear shifting pulling head 10 needs to overcome the damping that block selecting damping spring assembly 12 is formed it, this just reverses gear for choosing and adds the power of block selecting needs, after block selecting damping spring assembly 12 jumps onto gear shifting pulling head 10 convex, damping force no longer increases, reverse gear gear mouth place again by the rotary motion of mechanism operation gear shifting pulling head 10 when gear shifting pulling head 10 drives interlocking block 9 to arrive, shifting block on gear shifting pulling head 10 drives shifting fork-speed 7 motion of falling to realize extension and reverse gear by gear shift fork shaft-shift rug-five speed and the 6th fast 13 of falling in speed 6.
