The utility model which can effectively solve the problems that the service life of the variable speed gear is short, and the energy consumption of the variable speed gear is large, comprising a torque converter, a stepless transmission case and a stepped transmission case. The input shaft of the torque converter is connected with the driving shaft of the stepless transmission case, a driving wheel on the driving shaft of the stepless transmission case is connected with a driven wheel on the driven shaft of the stepless transmission case, and the driven shaft of the stepless transmission case is connected with the driving shaft of the stepped transmission case. The driving shaft is provided with a driving gear and a thumb wheel arranged between the two driving gears, the thumb wheel is connected with a shift lever by a change-over lever, and the driving gear is engaged with the corresponding driven gear on the driven shaft of the stepped transmission case; besides, the output end of the driven shaft of the stepless transmission case is provided with an output wheel. The utility model adopts a structure in the format of a clutch speed changer, a stepless speed changer and a stepped speed changer, and has the advantages of scientific and rational structure, easy installation, high performance, energy saving and long service life.
Description
One, technical field
The utility model relates to a kind of automobile-use speed change gear that assembles on Motor Vehicle.
Two, background technique
Speed change gear is the essential equipment of Motor Vehicle, often the speed change gear that uses has stepless speed changes devices and step change device, stepless speed changes devices is easily produced installation, lighter, but that when work requires its component capabilities is comparatively strict, and working life is short, the step change device, can realize multi-change speed, gear ratio is more constant, and the speed change gear of the Motor Vehicle reduction speed ratio that adopt also unreasonable more now, and adopt the more of fixing speed change, use its narrow limitation very big, employing combined type speed change gear, its combination is unreasonable, using effect is poor, life-span is short, and energy consumption is big, does not satisfy actual demand far away.
Three, model utility content
By above-mentioned situation and actual demand, the purpose of the utility model just provides a kind of automobile-use speed change gear, it is short working life effectively to solve speed change gear, the problem that energy consumption is big, the technological scheme of its solution is, by the moment of torsion torque-converters, infinitely variable transmission and stepped transmission case three parts constitute, the input shaft of moment of torsion torque-converters links to each other with the driving shaft of infinitely variable transmission, driving wheel on the infinitely variable transmission driving shaft links to each other with follower on its driven shaft through belt, its driven shaft links to each other with the driving shaft of stepped transmission case, thumb wheel between driving gear and wheel thereof is housed on this driving shaft, thumb wheel is connected with lever through Shift lever, driving gear is meshed with corresponding driven gear on the stepped transmission case driven shaft, the output terminal of electrodeless variable-speed case driven shaft has output wheel, and the utility model is scientific and reasonable for structure, easily installs, functional, energy saving increases the service life, and has economic and social benefit.
Four, description of drawings
Accompanying drawing is a structural profile plan view of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Provide by accompanying drawing, the utility model is by moment of torsion torque-converters 1, infinitely variable transmission 2 and stepped transmission case 3 constitute, the input shaft 4 of moment of torsion torque-converters 1 links to each other with the driving shaft 5 of infinitely variable transmission 2, driving wheel 6 on the driving shaft 5 links to each other with follower 9 on the driven shaft 8 through belt 7, driven shaft 8 links to each other with the driving shaft 10 of stepped transmission case 3, driving gear 11 is housed on the driving shaft 10,12 and the wheel between thumb wheel 13, thumb wheel 13 is connected with lever 15 through Shift lever 14, driving gear 11,12 respectively with driven shaft 16 on corresponding driven gear 17,18 are meshed, and the output terminal of electrodeless variable-speed case driven shaft 16 has output wheel 19.Moment of torsion torque-converters 1 also can adopt similar devices such as electric clutch.
The reduction speed ratio that stepped transmission case 3 of the present utility model is realized was advisable with 4: 1, can adopt different reduction speed ratio under different situations.
In use, power plant drive the work of moment of torsion torque-converters through input shaft 4, then the running by driving shaft 5 and driving wheel 6 through belt 7 (in case of necessity, belt also can adopt V-arrangement metal tape or metal bracelet etc., as long as can play transferring power all can) drive follower 9 and driven shaft 8, the driven shaft 8 of infinitely variable transmission drives driven gears 17 or 18 and driven shaft 16 by the driving gear 11 on the driving shaft 10 of stepped transmission case or 12, thereby stepped transmission case drives output wheel 19 work by its driven shaft 16 again and realizes power transmission, realize shifted by lever 15 and Shift lever 14 and thumb wheel 13, when starting to walk, increase the starting moment of torsion to reach, improve the climbing dynamics, reduce engine power when running up, prolong motor working life, save the energy simultaneously, during deceleration, 4: 1 reduction speed ratio realizes the reasonable utilization of the energy.The moment of torsion torque-converters mainly is promptly to prevent the fierce stretched operation to belt 7 in order to prevent in input impact to infinitely variable transmission during acute variation.
In addition, because mostly being 2800, changes by diesel engine, for reasonable energy utilization, improve diesel engine performance, when on slow-speed of revolution Motor Vehicle such as diesel engine, using the utility model, install a speed changer earlier additional before being preferably in input, improve the rotating speed of diesel engine, reduce moment of torsion, alleviate belt load, as can be seen by said structure, the utility model is to comprise clutch, the structure of the spread pattern that stepless and step change combines, scientific and reasonable, step change transmission can have 1 grade, 2 grades and reverse gear can also have 3 grades, 4 grades, reasonable use with effective realization high-speed diesel engine and belt performance, life-saving, energy saving has remarkable economical and social benefit.
