With reference to People's Transportation Press, " automobile construction " volume two, in February, 1999 third edition, its market is on sale, here no longer the narration.
Working procedure:
(1) engine starting process: because Starter 7 is fixed on the case of transmission by Starter fixing bolt 8.Input shaft 1 rotates in the direction of arrows, and this direction is assumed to be the sense of rotation of motor.First mono-directional overrun clutch 2 as shown in Figure 2, fixedly connected with starter receiver 3 in the outer ring 202 of its mono-directional overrun clutch 2, and the inner ring 201 of its individual event free wheel device 2 is fixedlyed connected with input shaft 1.When ato unit, Starter 7 driving gears 6 of Starter 7 drive starter receiver 3 and press the rotation of input shaft 1 direction of arrow, just mono-directional overrun clutch outer ring 202 rotates in the direction of arrows among Fig. 2, because the effect of mono-directional overrun clutch 2, make its outer ring 2 drive inner ring 1 rotation in the direction of arrows simultaneously,, move in the direction of arrows so drive input shaft 1 because inner ring 201 is connected with input shaft 1, power reaches motor by clutch, thereby realizes engine start.Because after above-mentioned mono-directional overrun clutch acts on engine start, Starter drives clutch makes input shaft rotate in the direction of arrows simultaneously, when being higher than Starter 7 and starting driving gears 6 and drive the rotational speed of starter receivers 3 as the speed of input shaft 1, because first mono-directional overrun clutch 2 can only rotate transfer motion power in the direction of arrows by outer ring 202, and can not be by input shaft 1 (as ratchet) effect to outer ring 202 transfer motion powers, input shaft 1 can not drive starter receiver 3 rotations, starter receiver 3 still keeps the drive speed of Starter driving gear, thereby the damage that can avoid Starter to produce owing to the high speed of motor.
(2) this speed changer process:
Be depicted as the neutral position of speed changer as figure one, this moment, speed change lever was placed on neutral position.When input shaft rotated, because second, third individual event free wheel device effect drives quill 9 and presses the rotation of Fig. 4 direction of arrow, input shaft three-range transmission 11, fourth gear 17 skies were enclosed within on the quill 9 of output shaft 1; Described output shaft reverse gear 30, five grades of gears 36 of output shaft, output shaft fourth gear 37, one grade of gear 45 sky of output shaft are enclosed within on the output shaft 1, so output shaft can not be driven.
Be fixed on each splined hub 26,27,28 on input shaft 1, quill 9, the output shaft 29 and 46 the outer surface and all be shaped on the identical external splines of joint gear ring profile of tooth that is adjacent gear, engage with each clutch collar that has internal spline accordingly respectively, and can endwisely slip along splined hub.
In this invention, still adopt synchronizer shift, synchronizer is a kind of clutch collar gearshift mechanism that has installed a cover synchronizer additional, and the effect of synchronizer is to make speed changer that the impact of soldered tooth not take place during gear shift in automobile is advanced.
This invention is that example illustrates with Audi's 100 transmission ratios.The engine idle rotating speed is drafted 800r/min.Switching speed is drafted and is 1500r/min, and the speed during general driver's gear shift is at 2300r/min-3000r/min, and because of the driving habits difference, the speed of motor is also inequality during gear shift during gear shift.1500r/min is essentially minimum switching speed of the present invention, in practical operation far above this speed.
During vehicle starting, desire to put into first gear, step clutch pedal formula clutch separation, handling speed change lever moves to left clutch collar 42 by shift fork, after one grade of gear engagement gear ring 44 engages, unclamp pedal, clutch, power just can be from input shaft 1 successively through second, the 3rd individual event free wheel device 4,19 as shown in Figure 4 the directions of arrow are input shaft 1 sense of rotation, input shaft drives second, the rotation in the direction of arrows simultaneously of the 3rd mono-directional overrun clutch inner ring 401, because the effect of above-mentioned single clutch, second, the equidirectional rotation is pressed in the 3rd mono-directional overrun clutch outer ring 402, with second, the 3rd mono-directional overrun clutch outer ring 402 affixed quill 9 are pressed the equidirectional rotation, be fixed in one grade of gear of input shaft 5 and 45 engagements of one grade of gear of output shaft on the quill 9, joint gear ring 44 in bindiny mechanism, clutch collar 42 connects or mesh splines hub 46, connects by spline and passes to output shaft 29.One grade velocity ratio is:
i
1＝z
35/z
5＝39/11＝3.545
Z represents the gear number of teeth in the formula, and its index number is represented the label of each gear in Fig. 1.First grade of forward gears that refers to the velocity ratio maximum, by that analogy.Below each gear velocity ratio:
i
2＝z
39/z
10＝40/19＝2.105

25=35/10=3.5 (reverse gear ratio)
Desire is thrown off one grade, can clutch collar 42 be moved to right by handling speed change lever, makes clutch collar and engages gear ring 44 disengaging engagements, and then speed changer is return neutral position.If change to second gear, handle speed change lever when a gear is put, step gas pedal, engine speed is arrived more than the 1500r/min, unclamp gas pedal, handle speed change lever, by handling speed change lever clutch collar 42 is moved to right, engage with 2 grades of gear engagement gear rings 40.Clutch collar 42 is at neutral position, and the moment before not engaging with 2 grades of gear engagement gear rings 40, input shaft 1 is consistent with quill 9 speed to be 1500r/min, and output shaft 29 speed are:
Output shaft rotating speed=input shaft speed/i
1After=1500/3.545=423.13r/min hangs second gear, after 39 engagements of input shaft intermediate gear 10, output shaft intermediate gear, input shaft 1 and the engine speed 800r/min that is consistent, output shaft 29 is consistent with automobile driving wheel anti-pass speed.
At this moment, because output shaft gear and input shaft gear velocity ratio change, output shaft is still with the 423.13r/min rotation, at the drive lower sleeve axle rotating speed of second gear position output shaft back pass power is:
Quill rotating speed=output shaft rotating speed * i
2=423.13 * 2.105=890.69r/min is quill speed 890.69r/min＞input shaft speed 800r/min just, because individual event free wheel device and quill effect, the speed discrepancy that can not produce owing to input shaft and output shaft influences the impact between gear when upgrading, and not stepping on clutch can be realized upgrading of speed changer.Step on gas pedal, when engine speed surpasses 890.69r/min, power once through input shaft 1, individual event free wheel device 4,19, quill 9, input shaft intermediate gear 10, output shaft intermediate gear 39, engage gear ring 40, clutch collar 42, splined hub 46, pass to output shaft 29 at last.
After speed-changing lever is hung second gear, when stepping on gas pedal and making motor 1500r/min, in like manner, clutch collar 14 is moved left to and engage gear ring 12 and engage and then can obtain third gear.After hanging third gear, the quill rotating speed is:
Quill rotating speed=1500/i
2* i
3=1500/2.105 * 1.429=1018.29r/min quill speed 1018.29r/min＞input shaft speed 800r/min, stepping on gas pedal makes motor accelerate to 1500r/min, the same speed change lever of handling, clutch collar 14 is shifted to the right to engage and obtains fourth gear with clutch collar 16, in like manner, the quill rotating speed is:
Quill rotating speed=1500/i
3* i
4=1500/1.429 * 1.029=1080.13r/min quill speed 1080.13r/min＞input shaft speed 800r/min, stepping on gas pedal makes motor accelerate to 1500r/min, the same speed change lever of handling moves left to clutch collar 33 to engage with clutch collar 35 to obtain five grades.In like manner, the quill rotating speed is:
Quill rotating speed=1500/i
4* i
5=1500/1.029 * 0.838=1221.57r/min quill speed 1221.57r/min＞input shaft speed 800r/min still can put into fifth gear, because the effect of individual event free wheel device can not produce the impact between gear.
When vehicle driving up and descending, ramp gear shift for convenience and performance engine braking, let slip the clutch and clutch collar 22 moved to left engages the gear ring joint at any time with quill, this invention and original speed changer have said function.
Travel for realizing that automobile is swung to, in case of transmission, be provided with short reverse gear shaft 23, (adopt as usual among Fig. 1 and launch the technique of painting, reverse gear shaft is drawn in the back upper place of input shaft).Reverse idler gear 24 is being overlapped in its sky, and it and input shaft reverse gear 25 are constant mesh gear.Clutch collar 33 is moved to right engage, promptly get reverse gear with engaging gear ring 31.Power from input shaft 1 successively through input shaft reverse gear 25,24,30, engage gear ring 31, clutch collar 33, splined hub 28, pass to output shaft 29.

During vehicle starting, desire to put into first gear, step clutch pedal formula clutch separation, handle speed change lever, by shift fork clutch collar 42 is moved to left, after one grade of gear engagement gear ring 42 engages, release the clutch pedal, clutch, power just can be from input shaft 1 successively through one grade of gear 5, one grade of gear 45 of output shaft, engage gear ring 44, clutch collar 42, splined hub 46, quill 9, second, the 3rd mono- directional overrun clutch 4,19 as Fig. 6, shown in 7, the direction of arrow is quill 9 sense of rotation, quill drives second, the 3rd mono-directional overrun clutch outer ring is rotation in the direction of arrows simultaneously, because above-mentioned single clutch effect, inner ring is passed to output shaft 29 by the equidirectional rotation.
Desire is thrown off one grade, can clutch collar 42 be moved to right by shift fork, makes clutch collar and engages gear ring 44 disengaging engagements, and then speed changer is return neutral position.If change to second gear, when speed change lever is put at a gear, step gas pedal, engine speed is arrived more than the 1500r/min, unclamp gas pedal, handle speed change lever, by shift fork clutch collar 42 is moved to right, engage with 2 grades of gear engagement gear rings 40 of output shaft.Clutch collar 42 is at neutral position, and the moment before not engaging with 2 grades of gear engagement gear rings 40 of quill, output shaft speed is:
Output shaft speed=input shaft speed/i
1=1500/3.545=423.13r/min at this moment, input shaft 1 and the engine speed 800r/min that is consistent, after input shaft and output shaft gear 10,39 engagements, because two gears have mono-directional overrun clutch effect in velocity ratio and the quill, so quill 9 speed are lower than output shaft 29 speed.
At this moment, because input shaft gear and sleeve shaft gear velocity ratio change, output shaft still rotates with 423.13r/min, but the quill rotating speed is:
Quill rotating speed=transfer input shaft speed/i
2=800/2.105=380.05r/min is quill speed 380.05r/min＜output shaft speed 423.13r/min just, because individual event free wheel device and quill effect, the speed discrepancy that can not produce owing to input shaft and output shaft influences the impact between gear when upgrading, and not stepping on clutch can be realized upgrading of speed changer.Step on gas pedal, when the motor accelerated service surpassed 423.13r/min when the quill rotating speed, power was once through input shaft 1, intermediate gear 10, output shaft intermediate gear 39, joint gear ring 40, clutch collar 42, splined hub 46, quill 9, mono-directional overrun clutch 4,19.Fig. 7 direction of arrow is the defeated sense of rotation of sleeve, and the sleeve input shaft drives the rotation in the direction of arrows simultaneously of mono-directional overrun clutch outer ring, because the single clutch effect, inner ring is pressed the equidirectional rotation, passes to output shaft 29.
After speed-changing lever is hung second gear, step on gas pedal and make engine speed reach 1500r/min when above, output shaft speed is:
Output shaft speed=1500/i
2=1500/2.105=712.59r/min
Unclamp gas pedal, engine speed is got back to idling speed (800r/min), clutch collar 14 is moved left to and engages gear ring 12 and engages and then can obtain third gear.After hanging third gear this moment, the quill rotating speed is:
Quill rotating speed=input shaft rotating speed/i
3=800/1.429=559.83r/min quill speed 380.05r/min＜output shaft speed 712.59r/min, because the effect of individual event free wheel device 4,19, output shaft are higher than the quill running, do not have and beat the tooth phenomenon, can realize not stepping on clutch, change to third gear by second gear.Stepping on gas pedal makes motor accelerate to 1500r/min.Output shaft speed is:
Output shaft speed=1500/i
3=1500/1.429=1049.69r/min
Unclamp gas pedal, the same speed change lever of handling is shifted to the right to clutch collar 14 to engage with clutch collar 16 to obtain fourth gear, and in like manner, the quill rotating speed is:
Quill rotating speed=800/i
4=800/1.029=777.45r/min quill speed 777.45r/min＜output shaft speed 1049.69r/min, in like manner the not stepping on clutch pedal can be realized gear shift.Step on gas pedal and make motor accelerate to 1500r/min, output shaft speed is:
Output shaft speed=1500/i
5=1500/0.838=1789.98r/min unclamps gas pedal, and the same speed change lever of handling moves left to clutch collar 33 to engage with clutch collar 35 to obtain five grades.In like manner, the quill rotating speed is:
Quill rotating speed=800/i
5=800/0.838=954.65r/min quill speed 954.65r/min＜output shaft speed 1789.98r/min/min still can put into fifth gear, because the effect of individual event free wheel device can not produce the impact between gear.
On vehicle during quite with descending, ramp gear shift for convenience and performance engine braking, let slip the clutch and clutch collar 22 moved to right engages the gear ring joint at any time with quill, this invention and original speed changer have said function.
Travel for realizing that automobile is swung to, make clutch collar 33 move to right with splined hub 32, engage gear ring 31 joints, promptly get reverse gear.Power from input shaft 1 once through gear 25,24,30, engage gear ring 31, clutch collar 33, splined hub 532, pass to output shaft 29.
Its reverse gear part is slightly different with embodiment 1, mainly be because quill 9 is installed on the output shaft 29, as do not have splined hub 532 to link to each other with output shaft can not to realize reverse gear, just because second, third mono-directional overrun clutch effect quill 9 can not drive the output shaft counterrotating.
The foregoing description experimental results show that:
It combines the present invention the motor vehicle starting part together with speed changer, thereby simplified the structure of automobile initiating means greatly, reduce manufacture cost, be convenient to the startup of motor again, simultaneously, make gear shift smooth and easy flexibly again, can realize vehicle starting under certain condition after not stepping on clutch finish the speed-change process that upgrades or lower category.The present invention has the following advantages:
