Abstract
The invention relates to a mechanical transmission, in particular to a force transfer continuously variable transmission with two-sided gear rings. A force transfer mechanism with two-sided gear rings is arranged in a drive system. The continuously variable transmission comprises the main parts including an input shaft (1), a front planetary carrier (2), a planetary wheel shaft (3), a rear planetary carrier (4), a big gear ring holder (5), a small gear ring holder (6), an input middle wheel (7), a big gear ring internal gear (8), a big gear ring (9), a big gear ring external gear (10), a small gear ring external gear (11), a small gear ring (12), a small gear ring internal gear (13), a walking planetary wheel (14), a driving planetary wheel (15), an output middle wheel (16), an output shaft (17) and a casing (18). The torsion force of the input middle wheel (7) is transferred and used for pushing the output middle wheel (16), so that a maximum torque can be output, a rotating speed can be approached after the load is reduced, and a fully-mechanical continuously variable transmission function is accordingly realized. Besides, the continuously variable transmission has the advantages of extremely simple structure, extremely low price, large transmission ratio, large continuous bearing force, high safety and reliability and long service life.
Description
Technical field
The present invention relates to a kind of mechanical speed changer, relate in particular to and adopt the double cog loop mechanism in a kind of transmission system and realize that with it torsion moves the two-sided gear ring power that promotes output and shifts stepless speed variator.
Background technique
At present the automatic Transmissions Technique of more use is automatic transmission technology with fluid torque converter and epicyclic train combination on automobile, but it has obvious shortcoming: velocity ratio is discontinuous, hydraudynamic drive efficient is lower, complex structure, safeguard inconvenience, another stepless change (CVT), it adopts metal driving belt and the variable master of working diameter, the follower incompatible transferring power that matches, but the CVT weakness is that the metal tape bearing capacity is little, transmitted power is limited, and the cost long-life is short, its control system very complex, cause supplementary costs to increase, 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 in decades urgent problem of machinery industry.The present invention adopts the double cog loop mechanism and realizes that with it torsion moves the two-sided gear ring power that promotes output and shifts stepless speed variator, when work directly according to load variations, fully automatically carry out stepless change moment of torsion variable speed running, the present invention has no homogeneous structure product and related data both at home and abroad.
Summary of the invention
Problem to be solved by this invention provides a kind of two-sided gear ring power and shifts stepless speed variator, it is in operation and adopts the double cog loop mechanism and with its power transfer characteristic, the torsion of input small gear directly is transferred to the output gearwheel, carries out fully automatically stepless change moment of torsion variable speed running.
The present invention is achieved in that in Fig. 1: two-sided gear ring power shift the stepless speed variator main parts size comprise take turns 7 in input shaft 1, front planet carrier 2, planet wheel shaft 3, rear planet carrier 4, canine tooth ring support 5, little gear ring base 6, the input, bull gear internal gear 8, bull gear 9, bull gear external gear 10, little gear ring external gear 11, little gear ring 12, little gear ring internal gear 13, the road wheel 14 that walks, drive take turns 16 in road wheel 15, the output, output shaft 17, casing 18 form; Its structure is: input shaft 1 is with output shaft 17 coaxial lines and by casing 18 supportings, front planet carrier 2 just has been unified into a framework with planet wheel shaft 3 and rear planet carrier 4 and has been supported by input shaft 1 and output shaft 17, canine tooth ring support 5 and little gear ring base 6 just have been associated with on the front planet carrier 2, bull gear 9 is supported by canine tooth ring support 5 and little gear ring base 6 respectively with little gear ring 12, wheel 7 has just joined in input shaft 1 and the input, walking, just connection is rear by planet wheel shaft 3 supportings with driving road wheel 15 for road wheel 14, wheel 16 has just joined with output shaft 17 in the output; The meshing relation of each gear, gear ring is: wheel 7 and bull gear internal gear 8 engagement in the input, bull gear external gear 10 and little gear ring external gear 11 engagements, little gear ring internal gear 13 and road wheel 14 engagements that walk, consist of the front row walk drive epicyclic gear train, drive wheel 16 engagements in road wheel 15 and the output, consist of after row's driver output epicyclic gear train.
Two-sided gear ring power shifts the stepless speed variator working principle and sees Fig. 1, when wheel 7 drives the road wheel 14 that walks with 15 counter-rotating of driving road wheel by bull gear 9 and little gear ring 12 in inputting, the torsion of wheel 7 just can be by the above gear-wheel gear-ring that is considered as third wheel in the input, its torque value rear directly being transferred to that slightly change drives road wheel 15 and promotes to take turns 16 in the output, since in the output wheel 16 radiuses be drive road wheel 15 radiuses N doubly, then wheel 16 can drive output shaft 10 with N times of moment of torsion and rotate also maximum output torque in the output, and no matter output shaft 17 rotating speeds what, the torsion that shifts can both be added on takes turns on 16 in the output, output speed will speed thereupon after load reduces, until output speed and input speed convergence, thereby finish reliably the Purely mechanical stepless shift function.
Two-sided gear ring power of the present invention shifts stepless speed variator, because the two-sided gear ring power of creative use transfer device, can be in maximum output torque, after reducing, load can also export maximum speed, thereby finished reliably the mechanical stepless speed-changing function, and textural anomaly is simple, price is very cheap, velocity ratio continuous bearing power is large, and the safe and reliable spreadable life is long.
