Description
Technical field
The utility model relates to transmission technology field, particularly a kind of stepless speed variator.
Background technique
The stepless speed variator of current application is generally the transmission form of single-stage, driving belt and the variable driven wheel of working diameter is adopted to match incompatible transferring power, can realize continuously changing of velocity ratio, common stepless speed variator has belt type and metal band type two kinds of variable v-belt drives.The transmission form of single-stage make stepless speed variator the numerical value of resultant gear ratio less, the numerical value as the single-stage stepless speed variator resultant gear ratio that current automobile is applied is less than 6, and when making galloping like this, engine speed is high, and Economy is poor.In addition, stepless speed variator generally common at present needs to arrange reverse gear and reverse gear control gear specially, increases control mechanism manufacture and controls difficulty, the cost of speed changer and rate of fault all can be increased.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of stepless speed variator by brand new, and the numerical value of its resultant gear ratio is large, does not need to arrange reverse gear mechanism and control gear in addition, to overcome the deficiencies in the prior art when realizing reverse gear.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of stepless speed variator, comprise variable v-belt drive, simple planetary arrangement, input shaft, described simple planetary arrangement comprises planet carrier, planet wheel, gear ring, sun gear, described variable v-belt drive comprises driving disc and driven disc, also comprise the driving gear and driven gear that are connected with a joggle, described driven gear is connected with sun gear, described driven disc is connected with gear ring, the driving disc synchronous rotary of described driving gear and variable v-belt drive, described planet carrier connects output gear.
The driven movable plate of described driven disc is arranged on the second axle, and the other end of described second axle connects gear ring.
Described driving disc comprises initiatively fixed tray, initiatively movable plate, and described active fixed tray, initiatively movable plate and driving gear are arranged on input shaft.
Compared with prior art, the utility model has the following advantages:
The utility model is on the basis of existing common stepless speed variator, by increasing simple planetary arrangement and main driven gear, it is made to obtain the change of significantly transmission ratio by the velocity ratio change controlling variable v-belt drive by a small margin, its speed changer resultant gear ratio numerical value is far longer than the resultant gear ratio numerical value of existing stepless speed variator, speed changer resultant gear ratio numerical value is more than more than 10, the speed changer resultant gear ratio numerical value that can realize in theory is for infinitely great, when making galloping, engine speed is lower, and Economy is improved.Speed changer does not need to arrange reverse gear mechanism separately in addition, makes speed changer structure compacter, reduces control mechanism manufacture and controls difficulty, and simultaneously the cost of speed changer and rate of fault also can decline.
Accompanying drawing explanation
Fig. 1 is the power transmission arrangment schematic diagram of the utility model stepless speed variator.
Embodiment
Below with reference to accompanying drawing and embodiment, the utility model is further described.
See Fig. 1, a kind of stepless speed variator of the utility model, comprise variable v-belt drive 16, simple planetary arrangement 9, input shaft 5, described simple planetary arrangement comprises planet carrier 10, planet wheel 8, gear ring 6, sun gear 7, described variable v-belt drive comprises driving disc and driven disc, also comprise the driving gear 4 and driven gear 12 that are connected with a joggle, described driven gear is connected with sun gear, described driven disc is connected with gear ring, the driving disc synchronous rotary of described driving gear and variable v-belt drive, and described planet carrier 10 connects output gear 11.Power is externally exported by output gear 11.
Variable v-belt drive 16 is made up of active fixed tray 1, initiatively movable plate 3, driven fixed tray 14, driven movable plate 15 and V-type band 2, can realize velocity ratio change among a small circle,
Initiatively fixed tray 1, initiatively movable plate 3 and driving gear 4 are arranged on input shaft 5, and driven fixed tray 14, driven movable plate 15, on the second axle 13, are connected with gear ring 6 by the second axle 13.Initiatively movable plate 3 and driven movable plate 15 can realize moving left and right by control mechanism, thus change variable v-belt drive 16 velocity ratio, when active movable plate 3 moves to left, when driven movable plate 15 moves to right simultaneously, variable v-belt drive 16 velocity ratio reduces, when active movable plate 3 moves to right, when driven movable plate 15 moves to left simultaneously, variable v-belt drive 16 velocity ratio then increases.
The ratio that the characteristic of the transmission ratio of this embodiment follows velocity ratio between moving gear 12 with driving gear 4, gear ring 6 number of teeth of simple planetary arrangement 9 and sun gear 7 number of teeth is relevant, show that transmission ratio formula is as follows through deriving:
=（1+）/(/+1/)
-transmission ratio;
Gear ring 6 number of teeth of-simple planetary arrangement 9 and the ratio of sun gear 7 number of teeth;
-variable v-belt drive 16 velocity ratio;
Velocity ratio between-driven gear 12 and driving gear 4.
If the velocity ratio between driven gear 12 and driving gear 4 is=-0.5, during ratio=2 of gear ring 6 number of teeth of simple planetary arrangement 9 and sun gear 7 number of teeth, transmission ratio is:
=3/(2/－2)
The transmission ratio of this embodiment and the corresponding relation of variable v-belt drive 16 velocity ratio as shown in table 1.
The velocity ratio of table 1 speed changer and the corresponding relation of variable v-belt drive velocity ratio
| 2 | 1.65 | 1.5 | 1.25 | 1.1 | 1.05 | 1 | 0.95 | |
| -3 | -3.8 | -4.5 | -7.5 | -16.5 | -31.5 | ∞ | 28.5 |
As can be seen from Table 1, variable v-belt drive 16 velocity ratio from 2 to 1.05 consecutive variations scopes be about 2 times, transmission ratio is from-3 to-31.5 consecutive variations then, resultant gear ratio numerical value is more than 10 times, thus the velocity ratio change realized by controlling variable v-belt drive 16 by a small margin obtains the change of significantly transmission ratio, the speed changer resultant gear ratio numerical value that can realize in theory is for infinitely great.In addition when variable v-belt drive 16 velocity ratio is less than 1, output gear 11 sense of rotation changes, and realizes reverse gear, does not need to arrange reverse gear mechanism separately.
