Abstract
A mechanical stepless speed variator is provided, which has continuously changed drive ratio, convenient variable speed control and large speed adjusting range; wherein a crankshaft drives a group of rocker arms, a group of rocker arms drive a group of unidirectional clutches, each group of unidirectional clutches drive a middle shaft to rotate in the same rotary direction, the middle shaft transfers the force to a middle shaft crankshaft, and the middle shaft crankshaft drives again a group of unidirectional clutches to drive an output shaft. The drive ratio is changed through changing the distance between the middle shaft and the input and output shafts.
Description
Affiliated technical field
The present invention relates to a kind of gear, especially a kind of mechanical stepless speed-changing machine structure.
Background technique
At present, known manual transmission adopts the gear train transmission.Because the number of teeth of every grade of gear train is fixed, so the gear ratio of each grade is a definite value. it by can be on axle gear in axial sliding, that meshes different gears reaches the speed change purpose, so its velocity ratio is discontinuous, speed Control is loaded down with trivial details.Discontinuous in order to solve the manual transmission velocity ratio, the deficiency that speed Control is loaded down with trivial details the invention provides a kind of stepless speed changing mechanism, and this mechanism not only velocity ratio is continuous, and speed Control is convenient.
Summary of the invention
The technological scheme that technical solution problem of the present invention is adopted is: with one group of rocking arm of crank-driven, one group of rocking arm drives one group of overrunning clutch, every group of overrunning clutch drives jack shaft and rotates to same sense of rotation, again by the jack shaft power transmission to the jack shaft bent axle, the jack shaft bent axle drives one group of overrunning clutch again and drives output shaft.By changing the continuous velocity ratio of change easily of distance between jack shaft and input shaft, output shaft.
The invention has the beneficial effects as follows can stepless change, and the variable-speed scope is big, and speed governing is convenient.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a plan view of the present invention.
Fig. 2 is a left view of the present invention.
Among the figure: 1 input bent axle, 2 jack shafts, 3 output shafts, 4 overrunning clutchs, 5 connecting rods, 6 contiguous blocks, 7 axially locating parts, 8 housings, 9 speed governing guide rods, 10 middle axle beds, 11 direct drive gears.
Embodiment
In Fig. 1, input bent axle 1 and contiguous block 6, housing 8 link to each other with revolute pair, contiguous block 6 and connecting rod 5 link to each other with sliding pair, connecting rod 5 and overrunning clutch 4 shell one, overrunning clutch 4 links to each other with jack shaft 2, bent axle on the jack shaft 2 is by linking to each other with sliding pair with link to each other contiguous block 6 and connecting rod 5 of revolute pair with contiguous block 6, connecting rod 5 and overrunning clutch 4 shell one, overrunning clutch 4 links to each other with output shaft 3, jack shaft 2 and input shaft 1, output shaft 3 are parallel, and direct drive gear links to each other with sliding pair with input shaft.
In Fig. 2, speed governing guide rod 9 one ends link to each other with middle axle bed 10, and the other end links to each other with housing 8.
Claims (3)
