Back action mechanism of belt type stepless gear

Abstract

The invention relates to a kind of back action mechanism of draper-type non segment speed changer. The invention is used to transfer dynamic force of positive-reverse direction, reach the different speed reducing ratio, and suit automotive vehicle drive components of different power equipment. It includes front draper wheel, source of power, back draper wheel, and twisting force cam set fitted over the front draper wheel and after draper wheel with ring. The front draper wheel and the source of the power is set on the front rotating shaft; the front draper wheel is made up of front active semi-wheel set on the front rotating shaft by slip cap and front fixed semi-wheel fixedly set on the front rotating shaft; the after draper wheel is made up of the back fixed semi-wheel and back active semi-wheel which are fitted over the back-shaft.; the twisting force cam set includes cam guide slot set on the active semi-wheel and corresponding cam pin in the cam guide slot; the clockwise rotation cam guide rail and the anticlockwise rotation cam guide rail are set on the inner wall of the cam guide slot; one end of the cam pin is set in the fixed semi-wheel, the other end is set in the cam guide slot and contacted to the opposite rotation cam guide rail and the reverse rotation cam guide rail.

Description

technical field [0001] The invention belongs to motor vehicle transmission components, in particular to a reverse gear mechanism of a belt-type continuously variable transmission. Background technique [0002] The belt-type stepless speed change mechanism has the advantages of low cost, simple structure, easy maintenance, and wide speed range, so it is more and more widely used in various power transmission machines. [0003] There are two common belt-type continuously variable transmission mechanisms: [0004] 1. In order to connect two sets of pulleys with a V-shaped rubber belt ring, that is, the driving pulley and the passive pulley, the mechanism only applies local butter lubrication to the inside of the pulley. The whole mechanism is dry and does not use oil lubrication. little motivation. [0005] 2. Combining many pieces of V-shaped sheet metal and composite materials on the steel belt to form a whole composite metal chain belt loop. The composite material and the...

Problems solved by technology

Although the power source can easily produce bidirectional output of forward rotation and reverse rotation, the continuously variable transmission as a torque conversion and transmission has always only had a single steering, so the entire power system cannot use a low-cost and smooth-shifting belt-type stepless transmission. Speed ​​change mechanism, only high cost gear box can be used
