The working principle of apparatus of the present invention is: drive A cylindrical planetary gear 4 and B cylindrical planetary gear 27 by internal gear 5 simultaneously, usual internal gear 5 is greater than two cylindrical planetary gears and is about 4-5 doubly, in such a configuration, it is a kind of state of speedup during transmission power, therefore, the power of motor is when being transferred to the input shaft 1 of torque converter, first need to arrange through a mechanical gear reducer arrangement, importing into the rotating speed of input shaft 1, decelerate to the speed ratio that internal gear 5 increases when driving two cylindrical planetary gears accordingly, internal gear 5 is first in the drive state of low rotation speed large torque power, make A planet pin 7 and the parts such as universal drive shaft 17 and output shaft 20, the rotating speed exported when High gear state works, with the rotating speed that motor inputs close to identical, make velocity ratio Proper Match and can adapt.
The application of this device on automobile, when initialization, the parts at each position also remain static, the power of motor first inputs from input shaft connecting flange 28 through retarder with lower rotating speed, pass to input shaft 1, again by internal gear land 2, internal gear 5 is driven to rotate, internal gear 5 drive simultaneously the A cylindrical planetary gear 4 that is attached to ring gear both sides and B cylindrical planetary gear 27 simultaneously stressed, due to the element that A cylindrical planetary gear 4 and A planet pin 7 are transmission power, be subject to the restriction of output resistance, the mode can't doing rotation is rotated, but under the effect of internal gear 5 driving force, A cylindrical planetary gear 4 and B cylindrical planetary gear 27, together with A planet pin 7 and B planet pin 26, one can be produced and only make revolution motion with internal gear 5, and the trend surmounted in internal gear 5 rotating speed is produced at process of revolution, now pay the single direction ratchet hock 6 be located at above A planetary pinion 4, support has limited this trend on the gear teeth of internal gear 5, like this will by internal gear 5, with another form, drive A cylindrical planetary gear 4 and B cylindrical planetary gear 27, together with fixing A planet pin 7 and B planet pin 26 in revolution situation, be similar to the form of a crank, strong torsion A planet pin 7, the revolution forming a rotation synchronous with internal gear 5 is held concurrently the mode of rotation, by outside outputting power such as universal drive shaft 17 parts such as grade, internal gear 5 now and A cylindrical planetary gear 4 and B cylindrical planetary gear 27 do not have the drive condition between gear, just rely on single direction ratchet hock 6, make A cylindrical planetary gear 4, card invests internal gear 5 by the state reversed by force, input shaft 1 is identical with the rotating speed of internal gear 5 with A planet pin 7, so just be equivalent to become distortion speed variator, be in lower rotating speed and larger torque force outputting power, be equivalent to the transmission state of traditional manual stationary axle speed changer when bottom gear, make automobile overcome the starting of larger resistance to travel.
Because two planet pins are bearing in inside tubular fixing frame 8 at relative position, when A planet pin 7 and B planet pin 26 are when revolving round the sun, tubular fixing frame 8 can be driven at the center rotating of shell 6, again by A balancing axle fixing frame 12 and B balancing axle fixing frame 24 and balancing axle 10, drive A stabilizer 14 and B stabilizer 22, double as the forms of motion overturn with another center of side direction, two stabilizers are while rotation, doublely change the sense of rotation being originally axle center with balancing axle 10, simultaneously using tubular fixing frame 8 sense of rotation as center of rotation, do the running of two kinds of forms of motion of another center lateral turnover.
Internal gear 5 is when twisting A cylindrical planetary gear 4 and B cylindrical planetary gear 27 at revolution motion, in the revolution in each week, also the rotation process of a circle is naturally produced, after there is spinning motion in A planet pin 7 and B planet pin 26, rotation followed by the cone planetary gear be arranged on two planet pins, A cone planetary gear 13 drives A stabilizer angular wheel 9, makes A stabilizer 14 make axial rotation.B cone planetary gear 23 drives B stabilizer angular wheel 25, and make B stabilizer 22 make axial rotation, A stabilizer 14 is contrary with the sense of rotation of B stabilizer 22.
The power of motor and rotating speed improve, the rotating speed of each drive gadget of input torque converter improves accordingly, after the rotating speed raising of A stabilizer 14 and B stabilizer 22, equilibrant produces and is strengthened gradually, namely equilibrant has part strength to start effect after strengthening, by balancing axle 10, A balancing axle fixing frame 12 and B balancing axle fixing frame 24, again by tubular fixing frame 8, limit the revolution speed of two planet pins and two cylindrical planetary gears, when internal gear 5 rotational velocity is constant, A planet pin 7 and B planet pin 26 and two cylindrical planetary gears be fixed in the above, occur and obtain controlling the trend that slows down of revolution motion, after the revolution speed that slowed down gradually, naturally must start the speed adding rotation gradually, A cylindrical planetary gear 4 and between B cylindrical planetary gear 27 and internal gear 5, start the form work driven with part, the parts such as A cylindrical planetary gear 4 and B cylindrical planetary gear 27 no longer include the rotation trend surmounting and revolve round the sun voluntarily in internal gear 5, be attached to the single direction ratchet hock 6 above A cylindrical planetary gear 4, start to lift restrictions, the drive condition that internal gear 5 and starting between A cylindrical planetary gear 4 and B cylindrical planetary gear 27 occurs between gear, velocity ratio starts to change and reduces, now, between internal gear 5 pairs of A cylindrical planetary gears 4 and A planet pin 7, the state transfer power of existing twisting, also two kinds of transmission states of the driving between gear are had, the rotating speed exported starts to accelerate gradually, torque force also starts step-down gradually, internal gear 5 is while with torque force form twisting A cylindrical planetary gear 4, while drive the twisting of A cylindrical planetary gear 4 and two kinds of transmission means of driving to carry out with driving force form, the dynamic action of internal gear 5 when A cylindrical planetary gear 4 by the drive form twisted form to gear, the torque force reduction gradually that A planet pin 7 grade exports, the revolution exported also raising gradually, torque converter gradually excessive to the mid ranger stage by bottom gear.
When the speed of motor continues quickening and car speed quickening, the rotating speed of two stabilizers is also higher, the equilibrant of stabilizer more obtains very large reinforcement, the revolution motion of control A cylindrical planetary gear 4 and B cylindrical planetary gear 27 is more and more slower, and the speed goes of rotation is fast, internal gear 5 and between A cylindrical planetary gear 4 and B cylindrical planetary gear 27, driving force ratio between formative gear gets more and more, and the ratio of twisted posture and strength fewer and feweri, torque converter work is excessive to the top gear stage gradually, it is driven faster that automobile high-speed exercises two stabilizers, the now stabilizer equilibrant that can produce also very huge, make the revolution motion of planetary mechanism confined very slow, revolution motion is close to static state, A cylindrical planetary gear 4 and B cylindrical planetary gear 27, substantially do not remake revolution mode to move, driven by internal gear 5 close to static state at revolution motion, due to larger than two cylindrical planetary gears 4-5 times of internal gear, original speed slowed down through retarder, returned by supplement, internal gear 5 drives A cylindrical planetary gear 4 with the form driven substantially, B cylindrical planetary gear 27 is also synchronously driven High Rotation Speed, the torque force now exported is minimum, the rotating speed exported is at most high state, the rotating speed of output shaft 20 is close with the rotating speed of motor, torque converter is in High gear state acting, make galloping.
The resistance travelled when automobile up slope or chance becomes large, or because of road conditions automobile carry out braking deceleration time, be subject to the restriction of driving and brake drag, the speed of A planet pin 7 and A cylindrical planetary gear 4 is slowed down, torque converter gets back to again the working state of original mid ranger, when run into running resistance reach maximum or the resistance that drives when maximum, torque converter until reduction of speed is to the minimum speed of low grade time initial and maximum torque force, low-speed running state when making automobile overcome larger running resistance.
