Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to including input shaft 1 inside Fig. 1, the present invention 5 gear automobile speed changer, variator, (input shaft 1 and input gear are
Integrally), main shaft 5 and five mainshaft gears 6, are provided with sliding sleeve 7 between mainshaft gear 6, the both sides of main shaft 5 have two full symmetric
Jackshaft 3, middle shaft transmission gear 2 is often engaged with the input gear of input shaft 1, remaining gear 4 on jackshaft 3 with corresponding
Mainshaft gear 6 often engages.Input shaft 1 is connected on case of transmission, and the front end of jackshaft 3 is connected on case of transmission, after
End is connected on bonnet housing, and main shaft 5 front end is connected in input shaft 1 by no outer ring cylinder roller bearing, and rear end is connected to
On bonnet housing, the coupling flange, output end disk of main shaft 5.
The work process of the present invention is：The power of electromotor is connected with the power of motor by clutch, passes to speed change
The input shaft 1 of device, the input gear being arranged on input shaft 1 is often engaged with middle shaft transmission gear 2, drives jackshaft 3 to carry out
Rotate, countershaft-gear 4 is often engaged with mainshaft gear 6, and mainshaft gear 6 dallies on main shaft 5.Sliding sleeve 7 passes through spline with main shaft 5
Connect, and selector fork 8 straddles on sliding sleeve 7, by steerable system control gear shifting pulling head moving gear shift shift fork 8 (one reverse gear for
Gear shifting pulling head moves guide block, and guide block drives shift fork axle 9 and a back fork 10 to move), selector fork 8 drives sliding sleeve 7 to move together
Dynamic, when sliding sleeve 7 is when the internal spline of mainshaft gear 6 is combined, main shaft 5 is integrally formed with mainshaft gear 6, turns according to certain speed ratio
Move and transmit power, then through ring flange 11, power is exported.
During upshift, intermediate shaft brake 12 participates in the process of work：
Variator, when low gear hangs high gear, first steps on clutch, the power input of open slew device, 7 times neutral gear positions of sliding sleeve.This
When due to the inertia of vehicle, main shaft 5 and think the rotating speed uniform rotation before continuing according to the gear that makes the return trip empty in ring flange 11 a period of time.
High gear mainshaft gear 6 rotating ratio main shaft 5 rotating speed now is much higher, and intermediate shaft brake 12 participates in work and provides resistance, will
The rotating speed of jackshaft 3, input shaft 1 and mainshaft gear 6 reduces rapidly, and the very short time just can be by high gear mainshaft gear 6 rotating speed
It is reduced near the speed of mainshaft and completes synchronization, then sliding sleeve 7 hangs high gear, completes upshift process.The work of intermediate shaft brake 12
Time is that sliding sleeve 7 disengages low gear gear to a period of time hung into before high gear gear.
