Title:
NON-STAGE TRANSMISSION
Document Type and Number:
Japanese Patent JP2016044727
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a non-stage transmission having strength which matches with torque fluctuations associated with the operation strokes of an internal combustion engine, and capable of achieving downsizing and lightening or cost reduction.SOLUTION: A non-stage transmission comprises: an input shaft to which driving force is transmitted from an internal combustion engine having plural cylinders; an output shaft; plural lever crank mechanisms each having an eccentric mechanism which has a cam disc eccentric to the input shaft and a rotary disc rotating eccentrically to the cam disc, and a swing link pivotally supported on the output shaft, and converting a rotary motion of the input shaft to swing motions of the swing links; and a mechanism for preventing unidirectional rotation of the swing links relative to the output shaft. The cam discs of the respective eccentric mechanisms are arranged eccentrically at every predetermined angle in the circumferential direction of the input shaft, and when setting a rotation angle position of the input shaft at the time point of passing over the top dead center in a stroke from a compression stroke to an expansion stroke in each cylinder as a reference position, a rotation angle difference between the reference positions of the respective cylinders whose orders of combustion are adjacent is different from a predetermined angle. At least one of the lever crank mechanisms is different from the other in strength against the driving force from the internal combustion engine.SELECTED DRAWING: Figure 9
