Description
Technical field
The utility model relates to a kind of speed changer, specifically, relates to a kind of stepless speed variator.
Background technique
Stepless speed variator principle is that several group gears equally not of uniform size with common gearbox have and point have conjunction under manipulating, and form different speed ratios, the pedal as bicycle rotates with different speed from chain-driving wheel through large small trochal disc.The thrust produced each group of gear due to different dynamics is not of uniform size, and the rotating speed causing gearbox to export also changes thereupon, thus realizes the low rotation regardless of class.
The difference of stepless speed variator and step type is, its gear ratio is not the point be interrupted, but a series of continuous print value, such as 0.85 can be changed to from 3.455 always.It had not both had numerous gear pairs of manual transmission, did not have the planetary gear set of automatic transmission complexity yet, and it mainly realizes the stepless change of speed ratio by driven wheel and metal block.
But existing stepless speed variator cannot realize real stepless change.
