Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further the utility model.
Embodiment 1：As shown in Figs 1-4, the present embodiment provides a kind of stepless automatic gear shifting in gear drive, including housing,
Differential gear, power self-locking device, transmission gear, differential gear by the planetary gear 4,3 of ring gear 3,3 planetary gear shaft 7,
Sun gear 6, central gear shaft 12, output shaft band planet wheel carrier 5, planet wheel carrier 10, pinion frame gear 13
Composition；Power self-locking device is made of worm gear 16, worm-wheel shaft 17, worm screw 15, worm shaft 18；Transmission gear is by the first conical gear
20th, the second conical gear 21, bevel pinion shaft 22, the first connection gear 24, the second connection gear 14, the first tower gear 23,
Second tower gear 11, gear ring drive gear 26 form.
Planet wheel carrier 10 is connected with pinion frame gear 13,21 phase of the first conical gear 20 and the second conical gear
Even, worm screw 15 is connected with worm gear 16, and gear 14 is connected with the small end of the first tower gear 23, the big end of the first tower gear 23 with
Second tower gear, 11 small end is connected, and 11 big end of the second tower gear is connected with gear ring drive gear 26, worm-wheel shaft 17, worm shaft
18th, band housing power input shaft 19, bevel pinion shaft 22 are installed on housing, and band housing power input shaft 19 is through central gear shaft
12 band sun gears 6, band planet wheel carrier output shaft 15 combine as a whole with planet wheel carrier 10.
Band housing power input shaft 19 imparts power to central gear shaft 12, and central gear shaft 12 imparts power to too
Positive gear 6, sun gear 6 is connect through planetary gear and planetary gear shaft with planet wheel carrier to be connected with planet wheel carrier 10
It connects, the rotation of planet wheel carrier 10 drives the gear of pinion frame, then is transmitted to the first connection gear 24, drives conical gear
Axis 22 drives the second conical gear 21, drives the first conical gear 20 again, drive worm shaft 18 again, drive worm screw 15 through snail again
Wheel 16, worm-wheel shaft 17 drive the second connection gear 14, the small end through the first tower gear 23, again through the big of the first tower gear 23
In end drives the small end of the second tower gear 11, big end through the second tower gear 11 drives gear ring drive gear 26, drives again
Gear ring 3 rotates, and ring gear 3 is connect with planetary gear 4, and planetary gear 4 imparts power to band planet wheel carrier output shaft 15
Export power；Otherwise ring gear 3 cannot drive planet wheel carrier 10 to rotate.
When the sun wheel speed of differential gear is certain, the rotating speed of planet wheel carrier and the rotating speed of ring gear can be with one
Fixed rotating ratio rises or drops (relative to the rotating speed of sun gear) simultaneously.Such as select x (sun wheel speed)+3y (gear ring rotating speed)=
The differential gear of 4z (rotating speed of planet wheel carrier).When the rotating speed of sun gear is 100 turns, ring gear rotating speed drop 40 switchs to 60
When turning, then the rotating speed drop 30 of pinion frame switchs to 70 turns, when ring gear rotating speed drop 80 switchs to 20 turns, then planet tooth
Wheel carrier drop 60 switchs to 40 turns.When 100 turns of the rotating speed drop of ring gear is namely 0, the rotating speed of planet wheel carrier is 25 turns, internal tooth
The rotating speed of circle drops again just generates reversion, and the rotating speed of planet wheel carrier also continues therewith toward decline.Rotating speed such as ring gear rises 40
Switch to 140 turns, then the rotating speed of planet wheel carrier rises 30 and switchs to 130 turns.When the rotating speed of ring gear, which rises 80, switchs to 180 turns,
The rotating speed liter 60 of so planet wheel carrier switchs to 160 turns.From this, it will be seen that the rotating speed of ring gear and planet wheel carrier
Rotating ratio is equal to 4 to 3, is fixed revolution ratio, according to this characteristic of differential gear, by the ring gear 3 of differential gear and poor
The planet wheel carrier 10 of dynamic device passes through the worm gear device with auto-lock function by their fixed rotating ratios and is connected, and make
Its steering is identical, and worm screw end is made to be connected with planet wheel carrier, and worm gear end is connected through connection gear with gear ring, and it is made to turn to phase
Together；When the power rotating speed that sun gear 6 obtains is 100 turns.The planet wheel carrier 5 and ring gear 3 of beginning power output are all
With 100 revolution of revolution of sun gear 6 with turn, if resistance torque is more than input torque, at this moment output shaft is with planet wheel carrier 5
Revolution begin to decline and through the first connection gear 24, the second conical gear 21, the first conical gear 20, worm screw 15, worm gear 16,
Second connection gear 14, the first tower gear 23, the second tower gear 11, gear ring drive gear 26, ring gear 3 are consolidated with 3 to 4
It is fixed to decline than together, until resistance torque is identical with input torque.When ring gear rotating speed drop 100 switch to 0 when cannot be again
It drops, then drops and just invert, at this moment the revolution of planet wheel carrier is 25 turns, increases output torque；Input torque is more than again
Torque is hindered, planet wheel carrier 10 improves revolution, sun gear 6 and the revolution of planet wheel carrier is made than constantly to become again
Change, reach speed change purpose.It such as arrives minimum revolution and does not overcome resistance torque still, engine is just put out a fire.
This machine enough limits it and cannot individually invert, it is necessary to which, with mutually rotating, such planet wheel carrier just has minimum revolution 25
Turn, as power by power input shaft band housing 19 inputted through central gear shaft 12, through sun gear 6, it is defeated by planet wheel carrier 5
Go out, just there are one minimum output revolutions；When being more than resistance torque such as input torque, planet wheel carrier just generates acceleration and carries
High revolution, it is on the contrary then reduce revolution, until reaching balance.Power is gushed by ring gear when being inputted for anti-stopping power makes planetary gear
Pedestal cannot get power, and ring gear is connected through connection gear with worm gear, at this moment the rotating speed of ring gear and planet wheel carrier
Rotating speed lifting can only be controlled by planet wheel carrier, so as to achieve the purpose that change gearratio automatically.
