Problems solved by technology

[0002] The existing continuously variable transmissions used in motor vehicles, whether they are chain or belt, generally adopt hydraulic pressure and speed regulation. Higher, compared with the stepped transmission, the continuously variable transmission has the characteristics of smooth and smooth shifting, but the stepped transmission has higher transmission efficiency and reliability than the continuously variable transmission

Embodiment Construction

[0014] Such as figure 2 As shown, this is a schematic diagram of the structure of the CVT of the present invention. The input wheel 2 and the output wheel 6 are all conical wheels, and a transmission belt 11 is connected in the middle, and the transmission belt 11 is stuck in the middle of the V-shaped regulator 7 . When adjusting the input-output transmission ratio, just move the adjustment control lever 3 and the adjustment control lever 5 to the right, and at this time, under the drive of the V-shaped regulators 7 and 12, the transmission belt 11 moves along the axial direction of the input wheel 2 and the output wheel 6. Moving to the right, the effective action wheel diameter of the input wheel 2 becomes larger, the effective action wheel diameter of the output wheel 6 becomes smaller, and the input-output transmission ratio becomes larger, otherwise the input-output transmission ratio decreases. 8 is driving drive wheel, and 10 is passive drive wheel.

Abstract

A continuously variable transmission comprises a housing, an input wheel, an output wheel, a transmission belt and a transmission belt controller. The continuously variable transmission is characterized in that at least one of the input wheel and the output wheel is a conical wheel, and each conical wheel is provided with a V-shaped regulator which controls the transmission belt to axially move on the conical wheel. The transmission belt is wound on the conical wheels and clamped in the V-shaped regulators. When moving in slides axially along the conical wheels, the V-shaped regulators drive the transmission belt to axially move along the conical wheels, thus the transmission ratio is changed.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a continuously variable transmission. technical background [0002] The existing continuously variable transmissions used in motor vehicles, whether they are chain or belt, generally adopt hydraulic pressure and speed regulation. Higher, compared with the stepped transmission, the continuously variable transmission has the characteristics of smooth and smooth speed change, but the stepped transmission has higher transmission efficiency and reliability than the continuously variable transmission. Contents of the invention [0003] The invention provides a continuously variable speed changer, which can realize continuous change in speed regulation and has a simple structure. [0004] A continuously variable transmission, including a casing, an input wheel, an output wheel, a transmission belt, and a transmission belt control device, is characterized in that: at least one o...
