The specific embodiment
This device is the new-type double-clutch type automatic gear shifting power drive of rear drive automobile, and it mainly is made up of the side clutch 37 in master clutch 36, change-speed box main tank, secondary box of gearbox, speed changer gear selecting and shifting mechanism 3 and the odd-side.
Described change-speed box main tank assembly comprises main tank primary shaft constant mesh gear 1, main tank five, six grades of synchros 2, main tank primary shaft six shift of gears 4, main tank primary shaft fourth speed gear 5, main tank three, fourth gear synchro 6, main tank primary shaft 3rd gear 7, main tank primary shaft second speed gear 8, main tank one, second gear synchro 9, one grade of gear 10 of main tank primary shaft, the main tank reverse gear is in conjunction with gear ring 11, main tank primary shaft reverse gearwheel 12, second 13 of main tank, main tank reverse gear shaft 26, main tank countershaft reversing gear 27, main tank reverse idler gear 28, one grade of gear 29 of main tank tween drive shaft, main tank secondary gear of intermediate shaft 30, main tank third-speed gear of intermediate shaft 31, main tank tween drive shaft 24, main tank tween drive shaft fourth speed gear 32, main tank tween drive shaft six shift of gears 33, main tank tween drive shaft constant mesh gear 34, main tank primary shaft 35.
Described secondary box of gearbox assembly comprises odd-side direct speed gear 14, odd-side tween drive shaft direct speed gear 15, odd-side synchro 16, odd-side high speed gear 17, odd-side tween drive shaft high speed gear 18 odd-side tween drive shafts 21, odd-side power take-off shaft 23.It is that side clutch driven gear 19 is fixed on the side clutch secondary part 20 by spline on the odd-side side clutch driving gear shaft that odd-side side clutch driving gear 25 is fixed on main tank tween drive shaft 24 by spline.Side clutch drive part 22 is bound up with odd-side power take-off shaft 23.Second 13 of main tank is same axis (also can connect by flange and odd-side direct speed gear wheel shaft) with odd-side direct speed gear wheel shaft, and main tank tween drive shaft 24 is same axis (also can connect by flange and odd-side side clutch driving gear shaft) with odd-side side clutch driving gear shaft.
For the rear drive heavy motor vehicle, in gearshift procedure, suppose that odd-side hangs into direct speed, promptly odd-side synchro 16 combines with odd-side direct speed gear 14, and main tank changes second gear by one grade, and change-speed box has following several running state (see figure 1):
1, when main tank moved by the control put in first gear, side clutch was in released state by control, and odd-side is a direct speed.Power is from 35 inputs of main tank primary shaft, be delivered to main tank tween drive shaft 24 through main tank primary shaft constant mesh gear 1 and main tank tween drive shaft constant mesh gear 34, be delivered to main tank one, second gear synchro 9 through one grade of gear 29 of main tank tween drive shaft and one grade of gear 10 of main tank primary shaft then, thereby be delivered to main tank second 13.By second 13 of main tank, power is delivered to odd-side power take-off shaft 23, outputting power through odd-side direct speed gear 14, odd-side synchro 16 successively.
2, be changed to by one grade in the process of second gear when the change-speed box main tank, the main tank synchro separates with gear by control, and second 13 of main tank be transferring power not.At this moment, power passes to main tank tween drive shaft 24 by the engagement of main tank primary shaft 35 by main tank primary shaft constant mesh gear 1 and main tank tween drive shaft constant mesh gear 34, pass through odd-side side clutch driving gear 25, side clutch driven gear 19 then successively, be delivered to side clutch secondary part 20.Because this moment, side clutch was in bonding state by control, then power can be delivered to side clutch drive part 22 by side clutch secondary part 20, passes at last on the odd-side power take-off shaft 23.In this process, though the gear pair of main tank and odd-side transferring power not promptly is in the power interruption state, can by main tank tween drive shaft 24 and side clutch in conjunction with outputting power, realize power shfit.
3, when main tank hung the second gear operation by control, side clutch was in released state by control.Power is from 35 inputs of main tank primary shaft, be delivered to main tank tween drive shaft 24 through main tank primary shaft constant mesh gear 1 and main tank tween drive shaft constant mesh gear 34, be delivered to main tank one, second gear synchro 9 through main tank secondary gear of intermediate shaft 30 and main tank primary shaft second speed gear 8 then, thereby be delivered to main tank second 13.By second 13 of main tank, power is delivered to odd-side odd-side power take-off shaft 23, outputting power through odd-side direct speed gear 14, odd-side synchro 16 successively.
If odd-side is hung into high speed gear, promptly odd-side synchro 16 combines with odd-side high speed gear 17, and main tank changes second gear by one grade, and then gear shift principle is identical with above-mentioned situation.Gearshift procedure and the above-mentioned situation of main tank between other adjacent gear is not quite similar, here no longer narration.
For other bearing capacities rear drive automobile littler than heavy automobile, odd-side is not established shelves, and in gearshift procedure, change-speed box has following several running state to see Fig. 2:
1, when main tank moved by the control put in first gear, side clutch was in released state by control.Power is from 35 inputs of main tank primary shaft, be delivered to main tank tween drive shaft 24 through main tank primary shaft constant mesh gear 1 and main tank tween drive shaft constant-mesh transmission gear 34, be delivered to main tank one, second gear synchro 9 through one grade of gear 29 of main tank tween drive shaft and one grade of gear 10 of main tank primary shaft then, thereby be delivered to main tank second 13.By second 13 of main tank, power is through odd-side power take-off shaft 23, outputting power.
2, change to the process of second gear by one grade when the change-speed box main tank, the main tank synchro separates with gear by control, and second 13 of main tank be transferring power not.At this moment, power passes to main tank tween drive shaft 24 by the engagement of main tank primary shaft 35 by main tank primary shaft constant mesh gear 1 and main tank tween drive shaft constant mesh gear 34, pass through odd-side side clutch driving gear 25, side clutch driven gear 19 then successively, be delivered to side clutch secondary part 20.Because this moment, side clutch was in bonding state by control, then power can be delivered to side clutch drive part 22 by side clutch secondary part 20, passes at last on the odd-side power take-off shaft 23.In this process, though the gear pair of main tank and odd-side transferring power not, can by main tank tween drive shaft 24 and side clutch in conjunction with outputting power, realize power shfit.
3, when main tank hung the second gear operation by control, side clutch was in released state by control.Power is from 35 inputs of main tank primary shaft, be delivered to main tank tween drive shaft 24 through main tank primary shaft constant mesh gear 1 and main tank tween drive shaft constant-mesh transmission gear 34, be delivered to main tank one, second gear synchro 9 through main tank secondary gear of intermediate shaft 30 and main tank primary shaft second speed gear 8 then, thereby be delivered to main tank second 13.By second 13 of main tank, power is through odd-side power take-off shaft 23, outputting power.
