Compared with prior art, the present invention has the following advantages:
The present invention 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 power-transmitting unit structural representation of the present invention.
Embodiment
Below with reference to accompanying drawing and embodiment, the present invention is described in more detail.
See Fig. 1, stepless speed regulation reverse gear structure of the present invention adopts variable v-belt drive and planetary gears to combine transferring power, comprises sun gear 10, planet wheel 9, planet carrier 14 and gear ring 8 by variable v-belt drive 18, simple planetary arrangement 12(), input shaft 5, driving gear 4, idle pulley 6, driven gear 13, second axle 15 and output shaft 11 form.Variable v-belt drive comprises driving disc and driven disc, driving disc comprises initiatively fixed tray 1, initiatively movable plate 3, driven disc comprises driven fixed tray 16, driven movable plate 17, and driving disc and driven disc are connected by V-type band 2 and transmit power, can realize velocity ratio change among a small circle.Stepless speed regulation reverse gear structure also comprises idle pulley, driving gear, driven gear, and idle pulley 6 is arranged on idler shaft 7, engages respectively with driving gear 4 and driven gear 13.Driven gear and sun gear link together, and planet carrier is connected with the driven disc of variable v-belt drive, and described gear ring is connected with output shaft 11, and the driving disc of described driving gear and variable v-belt drive is arranged on input shaft.Power is externally exported by output shaft 11.
Initiatively fixed tray 1, initiatively movable plate 3 and driving gear 4 are arranged on input shaft 5, and driven fixed tray 16, driven movable plate 17, on the second axle 15, are connected with planet carrier 10 by the second axle 15.Initiatively movable plate 3 and driven movable plate 17 can realize moving left and right by control mechanism, thus change variable v-belt drive 18 velocity ratio, when active movable plate 3 moves to left, when driven movable plate 17 moves to right simultaneously, variable v-belt drive 18 velocity ratio reduces, when active movable plate 3 moves to right, when driven movable plate 17 moves to left simultaneously, variable v-belt drive 18 velocity ratio then increases.
The transmission ratio of this embodiment
characteristic follow velocity ratio between moving gear 14 and driving gear 4
, gear ring 8 number of teeth of simple planetary arrangement 13 and the ratio of sun gear 11 number of teeth
relevant, draw transmission ratio through deriving
formula is as follows:

-transmission ratio;
Gear ring 8 number of teeth of a-simple planetary arrangement 13 and the ratio of sun gear 11 number of teeth;
-variable v-belt drive 18 velocity ratio;
velocity ratio between-driven gear 14 and driving gear 4.
If the velocity ratio between driven gear 14 and driving gear 4 is
=0.5, gear ring 8 number of teeth of planetary gears 12 and the ratio of sun gear 11 number of teeth
when=2, transmission ratio
for:
=2/(3/
