Abstract

The invention discloses a stepless transmission. The stepless transmission comprises an input component, an output component and columnar cones. A rotation axis of the input component and a rotation axis of the output component are collinear; the columnar cones are arranged at intervals around the rotation axes peripherally and clamped between the input component and the output component; each columnar cone comprises a middle cylindrical section, an input conical section and an output conical section, wherein the input conical section and the output conical section are arranged at two ends of the middle cylindrical section, and conical generatrix of each of the input conical section and the output conical section is perpendicular to the rotation axes. The input component is abutted against and tightly pressed on the conical surface of each input conical section and transfers the torque by means of rolling friction, the output component is abutted against and tightly pressed on the conical surface of each output conical section and transfers the torque by means of rolling friction, and the columnar cones are enabled to move axially to realize stepless gear ratio variation between the input component and the output component. The stepless transmission has the advantage that continuous variation of a contact radius between the columnar cones and each of the input component and the output component can be controlled to realize stepless transmission.

Description

technical field [0001] The invention relates to a continuously variable transmission, in particular to a cylindrical-cone continuously variable transmission. Background technique [0002] The transmission is a mechanism used to change the speed and torque from power transmission and control equipment (such as: engine), and can change the transmission ratio of the output shaft and the input shaft by fixing or stepping. A continuously variable transmission is a transmission that can realize continuous changes in the transmission ratio and obtain the best match between the transmission system and the engine operating conditions. However, the mechanical characteristics of most continuously variable transmissions in the prior art cannot meet the requirements of the dynamic characteristics of motor vehicle transmission, such as: constant power and constant torque control. [0003] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least o...
