Abstract

The present invention provides a stepless speed change device, characterized by comprising an external spline barrel, an internal spline belt wheel slice, a restoration internal barrel, a fixing flange disc, a restoration spring, wherein left end of the external spline barrel is arranged on the fixing flange disc, the right end is arranged with a belt wheel slice choke plug; the internal spline belt wheel slice has a plurality of slices slidably sleeved outside the external spline barrel, a belt groove is arranged between two slices, an internal spline belt wheel slice at rightest end is fixed with the restoration internal barrel; the restoration internal barrel can slidably be inserted in the external spline barrel, the right end of the restoration internal barrel and the left end of the external spline barrel install the restoration tension springs through two tension spring support plates. The invention has advantages of simple structure, low production cost, low use and maintenance cost, automatic speed change for accelerating vehicles when vehicles start, change speed, and the invention can be matched for agriculture tricycle, miniature tractor.

Description

(1) Technical field [0001] The invention relates to a continuously variable transmission device. (2) Background technology [0002] At present, many existing vehicles adopt stepless transmission. For drivers who are not skilled in shifting gears, the stepless speed change is simple and convenient to use, but the existing stepless speed changer has complicated structure, high cost, and high maintenance cost. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a continuously variable transmission device with simple structure and low manufacturing cost. [0004] The present invention is achieved through the following technical solutions: [0005] The continuously variable transmission device of the present invention is special in that it includes an outer spline barrel, an inner spline pulley, a reset inner barrel, a fixed flange, and a reset tension spring, wherein the left end of the outer spline ...
