the transmission ratio less than the first sun gear 2 and planetary gear 1, make third sun gear 5 relative to input shaft 4 i.e. first too Sun wheel 2 rotates for speedup, and the revolving speed for setting up planetary gear shaft 7 controls drive path, goes driving variable speed with third sun gear 5 Device 9 is fixedly mounted the first driving wheel 10 in the output end of stepless transmission 9 and engages with the second driving wheel 11, in the second driving wheel One-way lock mechanism 13 is installed between 11 and output shaft 12, and (according to the actual situation, the output end of stepless transmission 9 can directly drive Second driving wheel 11 and save the first driving wheel 10, the second driving wheel 11 can repack drive plate at this time), by stepless transmission 9 Come adjust planetary gear shaft 7 revolution and rotation speed so that adjust speed changer transmission ratio (from another angle analysis, The real deceleration transmission path for exactly forming the first sun gear 2, the first planetary gear 1, the second planetary gear 8, the second sun gear 14 is i.e. The biggish drive path of transmission ratio has directly made revolving speed control drive path, and increased planetary gear 6 only will with third sun gear 5 It is connect again with rotational speed governor after being driven the torque progress variable-speed torque-converting of bigger drive path, convenient for rotational speed governor to transmission The revolving speed of bigger drive path is controlled).Since the different degrees of revolution of planetary gear shaft 7 and rotation all can make third too Corresponding variation (revolution reduces 5 revolving speed of third sun gear, and rotation increases 5 revolving speed of third sun gear) occurs for sun 5 revolving speeds of wheel, As long as the revolving speed for therefore changing third sun gear 5 will force the revolving speed of planetary gear shaft 7 to become between minimum speed ratio and 1 Change.When 7 complete rotation of planetary gear shaft, torque just from the first sun gear 2, the first planetary gear 1, the second planetary gear 8, second too Variable diameter drive path of the transmission ratio greater than 1 formed between sun wheel 14 is driven, and when planetary gear shaft 7 revolves completely, first too Sun wheel 2 is automatically locked with the first planetary gear 1, the second planetary gear 8 and the second sun gear 14, and torque is just with the planetary biography equal to 1 Dynamic path transmission, 7 rotation of planetary gear shaft just control drive path by revolving speed to complete with revolution degree, make the biography of output shaft 12 It moves than in the variable diameter drive path transmission ratio greater than 1 and equal to stepless variation between 1 planetary drive ratio.Due to first sun The transmission ratio that the 2, first planetary gear 1 of wheel, planetary gear 6, third sun gear 5 are set up is less than 1, the transmission ratio of the output of third sun gear 5 In the variable diameter drive path transmission ratio less than 1 and equal to stepless variation between 1 planetary drive ratio, make final planetary gear shaft When 7 complete revolution, the revolving speed of third sun gear 5 is still equal with engine speed, but also can select first according to actual requirement The transmission ratio that sun gear 2, the first planetary gear 1, planetary gear 6, third sun gear 5 are set up, as long as making the third sun less than 1 The rotation speed change range of itself when controlling the rotation speed change of planetary gear shaft 7 of wheel 5 is smaller, becomes to the speed change of stepless transmission 9 Square area requirement is smaller, thoroughly solves planetary gear multi-way drive stepless speed variator and wants to the variable-speed torque-converting range of speed changer 9 Seek wider problem.
During torque transmission, wanted by stepless transmission 9 according to input power, output resistance torque and revolving speed and control The torque of some or all of third sun gear 5 is transmitted to rear class transmission mechanism by the stepless selection transmission ratio of the variation asked, and is controlled The stepless variation of the revolving speed of third sun gear 5, and make the stepless variation of the revolving speed of planetary gear shaft 7 and planet carrier 15, and then make multistage The stepless variation of transmission ratio of coaxial and fixed with the axis disjunctor planetary gear mechanism of planetary gear.Starting, input power it is smaller, When rear class resistance is larger or needs speed changer with maximum ratio transmissions, stepless transmission 9 selects maximum transmission ratio to be driven less Or not driving torque, enable 5 high speed of third sun gear or is freely rotated, one-way lock mechanism 13 (such as one-way clutch) locking Or release, planetary gear shaft 7 is at this time with most fast revolving speed rotation, and since the second sun gear 14 is difficult to rotate, the second planetary gear 8 is just It can revolve while on the second sun gear 14 on one side rotation and planet carrier 15 is driven to rotate backward the i.e. reversely revolution of planetary gear shaft 7, The torque that the second sun gear 14 obtains at this time is larger, and such as the second sun gear 14 cannot rotate forward, and stepless transmission 9 can be made to select Biggish or suitable transmission ratio lacks driving torque, 13 locking of one-way lock mechanism, make third sun gear 5 can high-speed rotation again The quick rotation of planetary gear shaft 7 can be suitably prevented, the torque for obtaining the second sun gear 14 is bigger, makes the anti-of planetary gear shaft 7 Reduce to revolution speed, stop reversed revolution or with the revolution of suitable revolving speed forward direction.
When the transmission ratio of speed changer reaches the first sun gear 2, the first planetary gear 1, the second planetary gear 8, the second sun gear 14 Between form transmission ratio when, planetary gear shaft 7 will not actively positive revolution and can only reversed rotation, make most or whole Torque energy is by input shaft 4 through the first sun gear 2, the first planetary gear 1, planetary gear shaft 7, the second planetary gear 8, the second sun gear 14, output shaft 12 is directly exported in a manner of variable diameter gear, the disjunctor planet tooth for keeping multi-stage planetary gear coaxial and fixed with axis Take turns mechanism output wheel with itself maximum transmission ratio driving torque.In variable-speed torque-converting operational process, one-way lock mechanism 13 is locked Only, suitable transmission ratio is selected to prevent 5 high speed of third sun gear or be freely rotated by stepless transmission 9, in addition planetary gear 6 and the The transmission ratio of three sun gears 5 less than the transmission ratio of the first sun gear 2 and planetary gear 1, prevents planetary gear shaft 7 from freely anti-again It revolves to the forward direction for transferring that planetary gear shaft 7 is forced to drive planet carrier 15 different degrees of certainly, while reducing planetary gear shaft 7 reversely The speed of rotation, keep multi-stage planetary gear coaxial and with the fixed disjunctor planetary gear mechanism of axis it is different degrees of with planetary gear The kind of drive of mechanism and the kind of drive of variable diameter gear while driving torque make entire speed changer that variable-speed torque-converting transmission be presented； When input power becomes larger, rear class resistance becomes smaller or speed changer is needed to have smaller transmission ratio, stepless transmission 9 selects smaller biography It moves and compares, make third sun gear 5 with lower rotational speed, enable planetary gear shaft 7 is slower freely reversely to transfer faster certainly just To revolution, realize that speedup subtracts square transmission, or even make third sun gear 5 to be close or equal to the rotational speed of the first sun gear 2, i.e., It prevents planetary gear shaft 7 from basic positive revolution is transferred, transmission ratio is made to reach or approach 1；When input power becomes smaller, rear class resistance When becoming larger or speed changer being needed to have bigger transmission ratio, stepless transmission 9 selects bigger transmission ratio, makes third sun gear 5 with more Fast rotational speed enables planetary gear shaft 7 freely reversely from slower positive revolution is transferred, to realize that the increasing square that slows down passes faster It is dynamic, variable speed bending moment task is converted by the way that planetary gear shaft 7 is different degrees of between revolution and rotation.
