Abstract

The invention discloses a cone-disk type continuously variable transmission with three-shaft speed regulation. The cone-disk type continuously variable transmission includes a driving shaft, a drivenshaft and a speed regulating mechanism. Through the improvement of the speed regulating mechanism, especially the improvement of the number and position of speed regulating shafts in the speed regulating mechanism as well as the connection mode with related components, the cone-disk type continuously variable transmission has a more compact structure, heat dissipation and lubrication are improved,the efficiency is enhanced, the cost is reduced, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of power mechanical transmissions, and in particular relates to a three-axis speed-regulating conical-disk continuously variable transmission. Background technique [0002] Since 2007, a series of electromechanical control cone-disc continuously variable transmissions have gradually matured, and have been widely used in the fields of road, off-road vehicles and general machinery due to their low cost, high efficiency and high reliability. In particular, its adaptability to pure electric driving conditions has prompted its gradual application in electric vehicles. [0003] The main system sub-functions of the cone-disk continuously variable transmission are pressurization and speed regulation. The speed regulation function is completed by the speed regulation system. [0004] A typical speed regulating system such as the structure disclosed in the patent CN103867678 "A Cone-disk Type Continuously Variable Transmissio...
