Metal chain tensioning device of oscillating-tooth infinitely variable transmission

Abstract

The invention provides a metal chain tensioning device of an oscillating-tooth infinitely variable transmission, and belongs to the technical field of vehicle infinitely variable transmission design and manufacturing. The device comprises a tensioning gear and a double-sided tooth-shaped metal chain, wherein an inner engaged surface of the double-sided tooth-shaped metal chain, i.e., the tooth shape engaged with the oscillating tooth is a single-chain-plate single-chip tooth; and an outer engaged surface of the double-sided tooth-shaped metal chain, i.e., the tooth shape engaged with the tensioning gear is a single-chain-plate double-chip tooth. The double-sided tooth-shaped metal chain can be always kept in an engaged state with the tensioning gear in a transmission process through relative movement of chain links, so that enough tensioning force is provided. The conventional tooth-shaped metal chain transmission tensioning device is simply designed and improved, so that the problem that tensioning force is in sufficient in the transmission process of the metal chain of the oscillating-tooth infinitely variable transmission is radically solved; and moreover, a tooth-shaped tensioning wheel replaces a conventional tensioning wheel, so that noises of the system are reduced, and the service life of the chain is prolonged. The novel double-sided tooth-shaped metal chain tensioning device can be widely applied to infinitely variable transmission of high-speed large-power vehicles and the industrial field.

Description

Technical field [0001] The invention relates to a metal chain tensioning device for a movable-tooth continuously variable transmission, which belongs to the technical field of automobile continuously variable transmission design and manufacturing. Background technique [0002] With the rapid development of the automobile industry and the increasing requirements of modern society on automobile performance, the movable-tooth continuously variable transmission, as an ideal continuously variable transmission, will be widely used in the automobile industry in the future. The traditional continuously variable transmission mostly uses friction transmission, which has low transmission efficiency and limited transmission torque. The movable tooth continuously variable transmission changes the friction of the traditional continuously variable transmission into meshing transmission, which greatly improves the transmission efficiency and the ability to transmit torque.
