Embodiment 1

[0018] A variable-diameter slider is set on the end face of the power input shaft to form a friction pair on the end face. The variable-diameter slider is coaxial with the planetary gear of the planetary gear train. By controlling the displacement of the axis line of the variable-diameter slider and the axis line of the power input, a The radius of the crankshaft, through the input power of the power input shaft, drives the variable-diameter slider to rotate, so that the axis of the variable-diameter slider rotates around the axis centerline of the power input shaft to form the crankshaft motion; the crankshaft passing through the axis of the variable-diameter slider The motion drives the rotation of the planetary gears of the planetary gear train, and under the limit action of the ring gear of the planetary gear train, the planetary gears transmit the power of the variable diameter slider to the output shaft, realizing the continuous stepless speed change function.

Abstract

The invention discloses a variable-diameter crankshaft type gear stepless speed change method and a speed changer. A variable-diameter slider is arranged on the end face of a power input shaft to form an end face friction pair, the variable-diameter slider and a planetary gear of a planetary gear train are coaxial, a crankshaft radius is formed by controlling the axis of the variable-diameter slider and the axis of the power input shaft, and the power input shaft inputs power to drive the variable-diameter slider to rotate and enable the axis of the variable-diameter slider to rotate around the center line of the power input shaft to form crankshaft movement. The planetary gear of the planetary gear train is driven to rotate by means of the crankshaft movement of the center line of the power input shaft, and power of the center line of the variable-diameter slider is transferred to an output shaft by the planetary gear under the limiting action of a gear ring of the planetary gear train to realize a function of continuous stepless speed change. Gear normally meshed shaft transmission is adopted for realizing continuous variable speed change, the speed change range is wide, the speed ratio ranges from zero to a fixed value, using a clutch for starting is not needed, large torque is available while 'skidding' is avoided, the speed change response is quick, and transmission efficiency is free of fluctuation.

Description

technical field [0001] The invention discloses a variable-diameter crankshaft-type gear stepless speed change method, which is an improvement to the existing gear constant mesh stepless speed change method, and can continuously and uninterruptedly change speed. At the same time, it also provides a transmission for realizing the above speed change method, for A mechanical non-friction transmission stepless transmission belongs to the technical field of mechanical transmission mechanisms. Background technique [0002] At present, mechanical gear constant mesh transmissions are all stepped transmissions. The mechanical continuously variable transmission is referred to as CVT in English. CVT mainly refers to belt transmission and traction transmission, both of which belong to friction transmission. [0003] CVT was invented by the Dutchman HGS Pouiding as early as 1896, and was first applied to motorcycles. Later, in 1958, the Dutch DAF Motor Company began to apply the belt-typ...
