Description
Technical field
The present invention relates to a kind of planetary gear mechanism, particularly a kind of wholly floating planetary gear mechanism belongs to the mechanical transmissioning technology field.
Background technique
Planetary gear mechanism can be realized slowing down and differential drive, and its application is very extensive.Traditional planetary gear mechanism is made up of four main members such as central gear, planet carrier, planetary pinion, gear rings.Except that planetary pinion is fixing, also have a member to fix at least in these four main members.This traditional planetary gear mechanism has only a power source, can only realize a kind of power delivery mode, and promptly when planetary gear mechanism was used for gearing down, the gear ring number of teeth was greater than the sun gear number of teeth, and power is imported from sun gear, gear ring output; When planetary gear mechanism was used for the speedup transmission, the gear ring number of teeth was less than the sun gear number of teeth, and power is imported from gear ring, sun gear output.At present China is carrying out the research and the trial-production of hybrid electric vehicle engine, needs to use a kind of planetary gear mechanism, and it requires planetary mechanism except that planetary pinion is fixing, the big member of its excess-three be central gear, planet carrier, gear ring none fix.Traditional planetary gear mechanism can't satisfy this requirement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of wholly floating planetary gear mechanism applicable to the hybrid electric vehicle engine system, thereby overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above technological scheme of the present invention: a kind of wholly floating planetary gear mechanism.Comprise splined shaft, spline gear baffle plate, ring gear, planetary pinion, planet axis, first planet carrier, second planet carrier, planet carrier baffle plate and sun gear, splined shaft is installed in the unsteady sun gear hole, and the external splines of splined shaft meshes with the internal spline of the spline gear baffle plate that floats; The external splines of spline gear baffle plate and the ring gear engagement of floating; Ring gear and planetary pinion engagement, planetary pinion and the sun gear engagement of floating, planetary pinion is installed on the planet axis; The right-hand member of planet axis is installed on the first unsteady planet carrier, and the left end of planet axis is installed in the hole of planet carrier baffle plate, and the planet carrier baffle plate is connected with second planet carrier that floats.
In the above-mentioned wholly floating planetary gear mechanism, described splined shaft is to be installed in the unsteady sun gear hole by sliding bearing.
In the aforesaid wholly floating planetary gear mechanism, described planetary pinion is to be installed on the planet axis by needle roller,
In the aforesaid wholly floating planetary gear mechanism, the right-hand member of described planet axis is to be installed on the first unsteady planet carrier by steel ball, and the left end of planet axis is to be installed in the hole of planet carrier baffle plate with interference fit.
In the aforesaid wholly floating planetary gear mechanism, described planet carrier baffle plate is to be connected with second planet carrier that floats by pin.
Beneficial effect of the present invention: sun gear, planet carrier, ring gear float entirely in the structure of the present invention, and none is fixed, and it can realize 5 kinds of different dynamic transfer modes:
1, power is imported by splined shaft, exports from sun gear.Its transfer route is: splined shaft Sill
The capable shallow luxuriant Yi sun gear of luxuriant value oceangoing ship Comedy ring gear Tochigi.This moment, the planet carrier rotating speed was zero, and power is delivered to sun gear from splined shaft, and mechanism is used for the speedup transmission.
2, power is imported by sun gear, goes out from first planet carrier, second planet carrier.Its transfer route is: the capable shallow luxuriant Yi gear ring reed show off of sun gear Tochigi is gone Qiang's bery 5. humorous capable Qiang berys 4 all of a sudden and is alarmmed the elegant β of being contrary to of back of the body Huan ψ and still lose Jia and hold the common bluebeard and fall show off and go the special bags of willow branches, framed by bamboo, for building dykes gown gruel of bery 5. humorous capable Qiang of Qiang all of a sudden and brag the lame Drung nationality
3, power is exported from sun gear by first planet carrier, the input of second planet carrier.Its transfer route is: first planet carrier, the elegant β of the being contrary to erosion of the capable shallow luxuriant Yi ring gear Yao Jia frame 4 towering back of the body Huan ψ of the second planet carrier Tochigi are gathered around the capable all of a sudden bery 5. humorous capable Macrophylla common bluebeards of Qiang of Qiang of show off and are taught the gruel of Zheng's Jia gown to brag the lame Drung nationality
4, power is respectively by splined shaft, sun gear input, from first planet carrier, the output of second planet carrier.Transfer route during the input of first power is: splined shaft Sill
Capable shallow luxuriant Yi first planet carrier of luxuriant value oceangoing ship Comedy ring gear Tochigi, second planet carrier; Transfer route during the input of second power is: capable shallow luxuriant Yi first planet carrier of sun gear Tochigi, second planet carrier, power passes to first planet carrier, second planet carrier from splined shaft and sun gear.First power input this moment can be different with the second power input power and rotating speed.Mechanism is used for the difference transmission, realizes converging of power.
5, power divides splined shaft, sun gear output by first planet carrier, the input of second planet carrier.Its transfer route is: first planet carrier, the capable shallow luxuriant Yi ring gear Sill of the second planet carrier Tochigi
Luxuriant value oceangoing ship Comedy splined shaft; First planet carrier, the capable shallow luxuriant Yi sun gear of the second planet carrier Tochigi, power is passed to splined shaft and sun gear respectively from first planet carrier, second planet carrier, and mechanism is used for the difference transmission, realizes the shunting of power.
Compared with prior art, wholly floating planetary pinion driver of the present invention mechanism is except that planetary pinion is fixing, the big member of its excess-three is that central gear, planet carrier, ring gear float entirely, none is fixed, have two power sources, can realize 5 kinds of different transmission of power, realize the shunting of power and converged the various transmission of power demands when having guaranteed hybrid power engine work.The present invention can be used in the coupling system and/or power segmenting system of hybrid electric vehicle engine system, mainly be that this traditional just fixed planetary gear mechanism is irrealizable because it can realize two kinds of power inputs and two kinds of power outputs simultaneously.
