In actual use, speed changer 5 is first dissected, makes 5 critical piece of speed changer such as input shaft 51, output shaft 52, dial
Fork 53, synchronizer, each power shift gear group etc., drill to shaft element, are carried out to the position that contacts with each other of geared parts
Cutting, if teeth cut half, to achieve the purpose that keep shape complete but destroy its rigidity.By the shell in gear set region
It is cut, exposes entire gear set；Then oil removing cleaning is carried out, is ground at the spine occurred by cutting, then through sandblasting, electricity
Plating step finally completes paint, is assembled into dissection transmission assembly.Respectively have on driving shaft, driven shaft one to five gear and
The gear set of neutral gear just has corresponding gear set under corresponding gear and is engaged.Respectively have on input shaft 51, output shaft 52
The gear set of one to five gear and neutral gear, just has corresponding gear set under corresponding gear and is engaged.
After the completion of dissecting speed changer 5, dust cover is removed, cut portion shell makes connecting rod and fork emerge.
After speed changer 5 installs, specific presentation process is as follows
1, the running inside whole observation study speed changer 5
(1) it is in neutral gear when shift bar is placed in front and back and left and right centre position,
(2) it manipulates shift lever 61 to deviate to the left, promote further along, be in one grade,
(3) it manipulates shift lever 61 to deviate to the left, then promotes backward, be in two grades,
(4) it when 61 neutral gear of shift lever, directly pushes ahead, is in third gear,
(5) it when 61 neutral gear of shift lever, promotes immediately rearward, is in fourth gear,
(6) it manipulates shift lever 61 to deviate to the right, promote further along, be in five grades,
(7) it manipulates shift lever 61 to deviate to the right, then promotes backward, be in reverse gear,
(8) when in each gear, joystick 7 is shaken, student is allowed to observe the rotation of gear,
(8) in operating gearshift procedure, student is allowed to observe 5 internal gear group conversion process of speed changer,
2, the effect of critical piece and the course of work in gearbox are observed respectively
(1) fixing piece 8 for disassembling connecting rod fork, unloads lower link fork, at this point, speed changer 5 can not shift gears, student is allowed to compare
Observation and the effect of study connecting rod fork and the course of work.
(2) fixing piece 8 for disassembling input shaft, unloads input shaft and driving gear, at this point, 5 unpowered input of speed changer, nothing
Method operates, and allows and student's paired observation and learns effect and the course of work of input shaft and driving gear.
(3) fixing piece 8 of dismantling dismantling output shaft, unloads output shaft and driven gear, at this point, speed changer 5 is unpowered defeated
Go out, can not operate, allows and student's paired observation and learn effect and the course of work of output shaft and driven gear.
(4) student is allowed to put into practice operation dismantling and installing connecting rods fork, output shaft and driven gear, input shaft and driving tooth
Wheel, careful their structure of observation.
According to above-mentioned principle, the present invention can also carry out change and modification appropriate to the above embodiment.Therefore, this hair
It is bright to be not limited to specific implementation mode disclosed and described above, some modifications and changes of the present invention should also be as to fall into this
In the scope of the claims of invention.
By it was verified that
1,5 shell of the present invention rationally cutting speed changer, demonstrates out 5 internal structure of speed changer, solves automotive transmission 5
Practical gear-shifting actuating mechanism is complicated, and especially practical 5 shell junction structure of speed changer is complicated, it is difficult to directly observe internal work
The problem of principle；Both static the structures such as driving shaft, driven shaft, shift fork, synchronizer, each power shift gear group can intuitively be shown, also might be used
From Dynamic Display shift process, each shift gear subordinate relation and power transmission line；5 left side of speed changer is dissected, complete
Whole to expose tooth group structure of reversing gear, demonstration can show reverse gear subordinate relation and power transmission line when reversing gear.
2, the present invention saves resource using the cleaning renovation of waste and old 5 assembly of speed changer, waste utilization；Structure connection is simple, tears open
Dressing is easy, is easy to directly observe；Round platform bottom is equipped with the universal caster wheel that can brake, both can any direction move Demonstration table, also may be used
Steady fixation is stopped at somewhere at any time, facilitates carrying and storage.3, operating power that speed changer 5 is provided by rotating joystick 7, with
Meaning grasps the velocity of rotation of gear set, more conducively teaching explanation；Electric power and fuel power machinery are abandoned to be provided for speed changer 5
Power so that entire Demonstration table volume smaller, weight is lighter, cost is lower.
4, in dissecting speed changer 5, be added can simple operations, the fixing piece 8 dismantled repeatedly, easily connecting rod can be pulled out
Fork, input shaft and driving gear, output shaft and output gear installation thereon thereon or dismantling, can both combine explanation speed change
Operation inside device 5, and can individually show connecting rod fork, input shaft and driving gear thereon, output shaft and thereon
Three mechanisms of output gear operation, meanwhile, student can practice operate mount and dismount these structures when,
More intuitively experience the structure of speed changer 5, improves learning effect.
