Abstract
The utility model relates to a stepless transmission, in particular to a tooth meshing stepless transmission, which resolves the problems existing in the prior stepless transmission that the transmission belt is easy to be damaged and can not bear large load. The tooth meshing stepless transmission comprises an output shaft and an input shaft. The input shaft is connected with a hydro cylinder, the piston rod of the hydro cylinder is connected with a rack and gear mechanism through a connecting rod, and the rack and gear mechanism is connected with the output shaft. A supporting swing cylinder is arranged between the input shaft and the hydro cylinder. Compared with the prior art, the utility model has the advantages that the stepless transmission can be used in large scale motor vehicles such as heavy vehicles, trains, etc.
Description
Technical field
The utility model relates to a kind of stepless speed variator, is specifically related to a kind of tooth engagement stepless speed variator.
Background technique
Common stepless speed variator has hydraulic mechanical type stepless speed variator and metal band type stepless speed variator.The stepless speed variator technology really is applied on the automobile the only time of more than ten years, but it than traditional manually and the advantage of automatic transmission be conspicuous: 1, simple in structure, volume is little, part lacks; 2, the work ratio coverage is little, and easy and motor forms ideal matching, thereby improves combustion process, and then reduces oil consumption and discharging; 3, have higher transmission efficiency, power loss is few, the Economy height.Certainly, existing stepless speed variator also has its weakness, damages easily such as driving belt, can't bear bigger load or the like.
Summary of the invention
The stepless speed variator driving belt damages the utility model easily in the prior art in order to solve, and can't bear the problem of bigger load etc., and a kind of tooth engagement buncher is provided.
The utility model adopts following technological scheme to realize; Tooth engagement stepless speed variator comprises input shaft, output shaft, it is characterized in that input shaft is connected with oil cylinder, and the piston rod of oil cylinder is connected with rack and pinion mechanism by connecting rod, and the rack pinion structure connects output shaft.Be provided with between input shaft and the oil cylinder and support the pendulum tube.
Described rack and pinion mechanism comprises the independent tooth bar that is connected with connecting rod, independent tooth bar cooperates with first ratchet and second ratchet of switched in opposite, first ratchet is coaxial with first gear and be connected with output shaft, second ratchet is coaxial with second gear, first gear and second gear engagement.
Described connecting rod also can be provided with two, article two, connecting rod is connected with first tooth bar, second tooth bar respectively, first tooth bar cooperates with first ratchet, second tooth bar cooperates with second ratchet, first ratchet and the second ratchet switched in opposite, first ratchet is coaxial with first gear, and second ratchet is coaxial with second gear, first gear and second gear while and output gear engagement, output gear connects output shaft.Above-described tooth bar can be collapsible, occupies little space.
The relative prior art of the utility model has following beneficial effect: stepless speed variator can be applied on the truck conspicuity marking, such as load-carrying lorry, train etc.
Description of drawings

Fig. 2 is the utility model embodiment 2 a structural representation
Among the figure: 1-input shaft, 2-oil cylinder, 3-connecting rod, 4-first ratchet, 5-second ratchet, 6-first gear, 7-second gear, 8-output gear, 9-output shaft, 10-first tooth bar, 11-second tooth bar, 12-independence tooth bar
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further, embodiment is used for illustrating of the present utility model, rather than it is imposed any restrictions.
Embodiment 1: tooth engagement stepless speed variator, comprise input shaft 1, output shaft 9, and input shaft 1 is connected with oil cylinder 2, and the piston rod of oil cylinder 2 is connected with rack and pinion mechanism by connecting rod 3, and the rack pinion structure connects output shaft 9.Be provided with between input shaft 1 and the oil cylinder 2 and support the pendulum tube.Described rack and pinion mechanism comprises the independent tooth bar 12 that is connected with connecting rod 3, independent tooth bar 12 cooperates with first ratchet 4 and second ratchet 5 of switched in opposite, first ratchet 4 is coaxial with first gear 6 and be connected with output shaft 9, second ratchet 5 is coaxial with second gear 7, first gear 6 and 7 engagements of second gear.
As shown in Figure 1, when connecting the input shaft counter clockwise direction of motor, oil cylinder drives independent tooth bar when the A point moves to the B point, and independent rack drives first ratchet is towards counterclockwise changeing, by clockwise rotating with the coaxial first gear driven output shaft of first ratchet.
When the B point moves to the A point, independent rack drives second ratchet and output shaft are towards clockwise rotating.Wherein first gear and second next round often mesh.
The length of stretching out by the oil cylinder control link realizes the variation of the bent axle radius of clean-up, thereby the continuous variation that realizes velocity ratio is stepless change.Dotted portion is a neutral state among the figure, unpowered output this moment.
Embodiment 2: tooth engagement stepless speed variator, comprise input shaft 1, output shaft 9, and input shaft 1 is connected with oil cylinder 2, and the piston rod of oil cylinder 2 is connected with rack and pinion mechanism by connecting rod 3, and the rack pinion structure connects output shaft 9.Be provided with between input shaft 1 and the oil cylinder 2 and support the pendulum tube.Described connecting rod 3 also can be provided with two, article two, connecting rod 3 is connected with first tooth bar 10, second tooth bar 11 respectively, first tooth bar 10 cooperates with first ratchet 4, second tooth bar 11 cooperates with second ratchet 5, first ratchet 4 and second ratchet, 5 switched in opposite, first ratchet 4 is coaxial with first gear 6, and second ratchet 5 is coaxial with second gear 7, first gear 6 and 7 whiles of second gear and output gear 8 engagements, output gear 8 connects output shafts.
But circular movement is changed into the back and forth movement of tooth bar by the bent axle of displacement, tooth bar is the driven gear back and forth movement again, two ratchets coaxial with gear are contained on the axle in opposite directions, and one of them ratchet is meshed with one group of change gear, back and forth movement is become in the same way rotate.By changing the radius of gyration of displacement bent axle, can change the rotating speed of output shaft.
