Greatly, the speed changer of increase is difficult to reasonable installation in automobile originally crowded narrow and small engine chamber, so as to only increase engine chamber
Space, matching same torque engine torque condition under, speed changer radial dimension increase, cause arrangement be stranded
Difficulty, volume and weight increase, cost is consequently increased, and is unfavorable for the Miniaturization Design of engine chamber.It is to solve because of input shaft at present
Become big with the synchronizer radial dimension on output shaft and cause the synchronizer on two axles to form the problem of occupy-place is interfered mutually, generally
It is that the relative design of the diameter dimension of input shaft and output shaft is smaller, but such result, which is the rigidity for causing axle, to be reduced.Become
During fast device work, due to thering is the force of periphery, radial load and responsive to axial force, especially output shaft to bear torque and curved on gear
Square, it is the corner of amount of deflection and axle that axle is produced in vertical plane in the horizontal plane working gear to be influenceed maximum, once axle
Rigidity reduce, especially the insufficient rigidity of output shaft will destroy the correct engagement of gear, to the intensity of gear, wearability and

On fast gear 18, most power is passed through differential mechanism 17 afterwards；The slip that gearshift stirs synchronizer by fork is bought or get by illegal means
When six gears：First 56 gear synchronizers 7 engagement synchronous with the gear driven gear 6 of output shaft 15 6, the power of input shaft 2 passes through six gears
It is delivered to after the gear pair that driving tooth and six gear driven gears 6 are constituted through five or six gear synchronizers 7 on output shaft 15, then by advancing
Gear output gear 15-1 is delivered to power on final gear 18, and most power is passed through differential mechanism 17 afterwards.Gearshift machine
The slip that structure stirs synchronizer by fork is bought or get by illegal means when reversing gear, first reverse gear synchronizer 22 and reverse gear gear 21 synchronously connect
Close, the power of input shaft 2 with the gear driven gears 14 being meshed of a gear driving tooth 2-1 on input shaft 2 by being delivered to and a gear
On the reverse gear gear 21 that driven gear 14 is meshed, then it is delivered on reverse gear shaft 20 through reverse gear synchronizer 22, then through reversing gear
Output gear 20-1 is delivered to power on final gear 18, and most power is passed through differential mechanism 17 afterwards.When not putting into gear,
When the slip cap of each synchronizer is located at the splined hub center of each synchronizer respectively, each gear driven gear is all in output on output shaft 15
Dallied on axle 15, output shaft 15 does not export power, now speed changer is in neutral position state.
Using foregoing invention, its structure arrangement is simple, compact, can increase input shaft and output shaft rigidity in speed changer, together
When can also increase the intensity of shift gear, wearability and reduction gearbox work noise, improve gearbox using reliability and
Service life.
