Description
One, technical field
The invention belongs to the mechanical transmissioning technology field, be specifically related to the speed change gear on motor-driven and the human-powered vehicle.
Two, background technique
The mechanical transmission of existing automobile can not be finished automation separately, and fuel oil was not wasted in manually-operable at that time.Existing surging and electronic automatic gear-shifting device can not be finished speed change work separately, also wants mechanical transmission at last, can not omnidistance stepless change.The shift device excessive fuel consumption of surging, the pressure system oil pressure derives from motor, is reactive power consumption for walking, so excessive fuel consumption.The torque-converters of the electronic shift device of liquid can not omnidistance stepless change, also will rely on automatic gear-shifting to finish at last, oil gas door aperture can only be cut apart by each class, in case motor can not be by half grade of burning in the time of half grade for running speed, because about switching point, do not have the speed change possibility, so excessive fuel consumption.And the at this moment experienced driver of non-automatic car can change valve opening, instead more fuel-efficient than automatic gear-shifting.The hydraulic part processing time consuming, cost is big, and can not finish speed change separately again, and that just surges or electronic not as removing this part.In this case, automatic gear-shifting is convenient unlike manual shift, no matter use what means, final high-power powerdriven terminal also will be finished by machinery.
Three, summary of the invention
The purpose of this invention is to provide a kind of stepless automatic gear shifting in gear drive, realize the stepless automatic transmission of vehicle, and driver is freed from the analysis operation of complexity.
According to the rigid motion composition principle, two or more rigid motion is synthesized a kind of motion, be the synthetic of motion; Various compound movements can be decomposed into several basic exercises, are the decomposition of motion.The present invention is exactly by using the combination of two kinds of kinds of drive of planetary moving axis transmission and ordinary transmission on one group of gear to realize automatic stepless speed change.The technical solution used in the present invention is: the gear automatic stepless speed variator comprises two planetary gear set and self-locking mechanism, startup clutch, each planetary gear set is configured to by central gear, planetary pinion, internal gear and planetary pinion, central gear is meshed with planetary pinion, planetary pinion is meshed with internal gear, planetary carrier connects with planetary wheel shaft, and the planetary carrier of two planetary gear set is an integral body.Self-locking mechanism is installed between two groups of planetary pinions, self-locking mechanism is by the oscillation center gear, free planetary pinion, swing internal gear and coupling, fixedly pin and fixedly pin sliding bearing formation, the oscillation center gear is meshed with free planetary pinion, free planetary pinion is meshed with the swing internal gear, the circular hole that center hole and a plurality of symmetries are arranged on its oscillation center gear, in each circular hole, pin is housed, pin is fixed on the frame, the oscillation center gear can be swung in the scope of circular hole greater than pin, the swing internal gear of self-locking mechanism and second group of planetary internal gear are linked together by coupling, and its oscillation center gear cooperates with first group of planetary internal gear excentric sleeve by bearing.Start clutch and be between the internal gear of first group of planetary gear set and planetary carrier and add some rollers, there is sphenoid surface pack into the position of roller of planetary carrier, makes the relative planetary carrier of internal gear can only do one-way rotation.
Faster rotating wheel can be by artificial also can being formed by objective factor.The torque that the rotating speed identical with wheel and wheel need must be in time sent in needed torque when adapting to wheel, speed changer, has realized automatic speed changing even if reach this requirement.Automatic transmission is exactly that timely feedback speed with wheel feeds back in the speed changer by exporting from speed changer with same speed after the processing again, promoting car ceaselessly walks, automatic transmission that Here it is, promptly to equal the speed changer output speed be exactly automatic transmission to the wheel feedback speed.Stepless automatic gear shifting in gear drive is exactly that two groups of planetary gear set are linked together by the transmission self-locking mechanism, the central gear of first group of planetary gear set is the input gear of speed feedback, the central gear of second group of planetary gear set is the speed changer power output gear, by planetary carrier input power.The purpose that the gear CVT (continuously variable transmission) will reach is:
Power output speed=wheel feedback speed formula I
Because the first group switching centre gear speed is the wheel feedback speed, the second group switching centre gear speed is the power output speed.So formula I should be write as:
The second group switching centre gear speed=first group switching centre gear speed formula II
Velocity ratio at first is described.
For first group of planetary gear set, central gear is a driving gear, so following formula should be:
The right-hand rotation of central gear causes internal gear to turn left by planetary pinion, so velocity ratio should be a negative value.Following formula should be:
Formula IV establishment when supposing that planetary carrier fixedly.The rotation of calculating planetary carrier also must make central gear fix.Planetary carrier also will make the planetary pinion public affairs circle except making the planetary pinion rotation when rotating, so velocity ratio should add 1.
For second group of planetary gear set, internal gear is a driving gear, and central gear is a driven gear, so:
Speed calculation:
Driving link rotating speed * velocity ratio=Passive part rotating speed formula VIII
According to the power composition principle, first group of planetary gear set internal gear speed should be synthetic by the planetary carrier speed and the first group switching centre gear speed.The closing of product of these two speed and velocity ratio separately is exactly first group of internal gear speed.
According to the power composition principle, second group of planetary gear set central gear speed should be synthetic by planetary carrier speed and second group of internal gear speed.The closing of product of these two speed and velocity ratio separately is exactly the speed of central gear.Because self-locking mechanism is one to one transmission, so second group of internal gear speed is identical with first group of internal gear speed.
Following formula I～X only limits to the inner gear ratio of first group of gear when identical with second group of gear inside gear ratio, otherwise formula I will be false.
The present invention is fit to various road vehicles such as automobile, motorcycle, bicycle, can omnidistance stepless automatic transmission, reduce reactive power consumption.
