Description

Power conversion planetary stepless variator

Technical field

The present invention relates to a kind of mechanical speed changer, relate in particular to a kind of transmission system is carried out torsion conversion and then conversion moment of torsion with the frictional slip power of two groups of planet schedule angle speed difference generations power conversion planetary stepless variator that is used for.

Background technique

The automatic Transmissions Technique of more use is the automatic transmission technology with fluid torque converter and epicyclic train combination on automobile at present, but it has significant disadvantages: velocity ratio is discontinuous, and hydraudynamic drive efficient is lower; Complex structure is safeguarded inconvenience, a kind of in addition stepless change (CVT); Its adopts metal driving belt and the variable driven wheel of the working diameter incompatible transferring power that matches, but the CVT weakness is that the metal tape bearing capacity is little, and transmitted power is limited; And the cost long-life is short; Its control system is quite complicated, causes supplementary costs to increase, and can only be used for car at present.Therefore, develop a kind of safe and reliable, simple in structure, easy to process and cheap stepless speed variator, just become mechanical industry urgent problem for many years.The frictional slip power that the present invention's initiative produces with two groups of planet schedule angle speed differences is carried out the power conversion planetary stepless variator of torsion conversion; Can when work, carry out stepless change moment of torsion variable speed running fully automatically, the present invention does not see product and the related data that homogeneous structure is arranged both at home and abroad as yet.

Summary of the invention

Problem to be solved by this invention provides a kind of power conversion planetary stepless variator, and it carries out stepless change moment of torsion variable speed running fully automatically in the course of the work directly according to load variations.

The present invention is achieved in that in Fig. 1: power conversion planetary stepless variator main parts size takes turns 3 by taking turns among input shaft 1, the row among 2, two rows, row frame dish 4, road wheel axle 5, a seniority among brothers and sisters wheel 6, one row's wheel rim 7, two seniority among brothers and sisters wheels, 8, two row's wheel rims 9, clutch wheel 10, retainer ring 11, output disc 12, output shaft 13, forward clutch 14, reverse clutch 15, casing 16 are formed; The meshing relation of its structure and each planet wheel is: input shaft 1 and output shaft 13 coaxial lines and by make on housing 16 supporting, the input shaft 1 just be associated with take turns among the row take turns among 2, two rows 3, one seniority among brothers and sisters wheel, 6 and two seniority among brothers and sisters wheels 8 by road wheel axles 5 supportings that just joined on the row frame dish 4, row's wheel rim 7 through retainer ring 11 be installed on the output disc 12, two arrange that wheel rims 9 are installed on the clutch wheel 10, output disc 12 and output shaft 13 has just joined, forward clutch 14 is installed in clutch wheel 10 and output disc 12 between; Can carry out to separate with combination, reverse clutch 15 being installed between road wheel frame dish 4 and the casing 16, can carrying out row frame dish 4 and casing 16 and separate and combines, take turns among the row 2, one seniority among brothers and sisters wheel, 6 and one row's wheel rim 7 and constitute and take turns 3, two seniority among brothers and sisters wheels, 8 and two row's wheel rims 9 among the first rows of planetary schedule, two rows and constitute to take turns among the second rows of planetary schedule, the described row and take turns 3, two among the first rows of planetary schedule that 2, one seniority among brothers and sisters wheel, 6, one row's wheel rim 7 constitutes and two rows and rank and take turns 8, two and arrange the second rows of planetary schedule of wheel rims 9 formations clutch wheel 10 and output disc 12, the pattern that can be made into epicyclic gear train also can be made into pattern, described forward clutch 14, reverse clutch 15 its clutching forces that planetary roller arranges and can use mechanical force also can use electromagnetic force and hydraulic coupling.

Its working principle is: in Fig. 1, and when input shaft 1 rotates, the first planet schedule and the second planet schedule; They will be with the running of the kinetic characteristic of planet schedule, if the reverse clutch 15 of carrying out clutch with mechanical force, electromagnetic force, hydraulic coupling will be gone frame dish 4 and combined with casing 16, taking turns 2 during then the first rows of planetary schedule will be imported with a row be power; Drive row's wheel rim 7, output disc 12, output shaft 13 counterrotatings output, and the second rows of planetary schedule dallies owing to forward clutch 14 is in separated state, this kind operating mode is reverse gear; If reverse clutch 15 is in separated state, row's wheel rim 7 is in motionlessly in that starting is instantaneous, and then wheel 2 will drive the rotations of slowing down of a seniority among brothers and sisters wheel 6, row frame dish 4 in row's input; Simultaneously wheel 3 also drives two seniority among brothers and sisters wheels 8 and rotates among two rows, because the parameter of two groups of planet schedules is slightly variant, if forward clutch 14 is in bonding state; Then will produce frictional slip between clutch wheel 10 and the output disc 12, and must frictional slip amount that directly influences mechanical efficiency and frictional slip power be controlled at certain numerical value during design, can the torsion of input shaft 1 be shifted to row's wheel rim 7 and through exporting after retainer ring 11, output disc 12 and the output shaft 13 implementation torque conversions through the conversion of the frictional slip power of generation between clutch wheel 10 and the output disc 12; It turns to identical with input redirect, no matter because the rotating speed of output shaft 13 is what, the torsion through the frictional slip force transformation is added on one all the time and arranges on the wheel rim 7; And the radius of wheel rim 7 is i times of wheel 2 in the input; Can be when load be big, the moment of torsion that makes transmission output shaft 13 is big and rotating speed is less, and but can accelerate gradually at the rotating speed that load reduces rear output shaft 13; Up to a seniority among brothers and sisters wheel 6; Two seniority among brothers and sisters wheels 8 have only revolution and the rotation rotating speed levels off to zero, and be convergence output in 1: 1 this moment, like the combination pressure of further increasing forward clutch 14; Cause the frictional slip amount to be decreased to zero and locking; This moment, mechanical efficiency was the highest, and can realize the energy-conservation running of cruising of output in 1: 1, thereby accomplished stepless speed change function automatically.

Power of the present invention conversion planetary stepless variator is firmly changed planetary wheeling mechanism because innovation makes, and makes it can be in the output Maximum Torque;, load can also export maximum speed after reducing; Thereby it is accomplished the mechanical stepless speed-changing function reliably, thereby simple in structure, cheap; Velocity ratio continuous bearing power is big, and the safe and reliable spreadable life is long.
