Problems solved by technology

[0003] 1. The transmission belt bears the lateral pressure of great load for a long time and is easy to relax; the service life is short
[0004] 2. The opening and closing action between the movable disc and the positioning disc of the driving disc group must be reflected by the lateral pressure of the transmission belt, so as to affect the opening and closing action of the passive disc group 20, the action disc 21 and the fixed disc 23. This indirect The slow action relationship of the formula makes the correct transmission ratio unstable
[0005] 3. The passive disc group driven by the transmission belt, due to the frequent slippage between the fixed point disc and the action disc, causes the transmission belt to be easily twisted and high-frequency vibration; in addition to affecting the life of the belt, it will also cause poor power transmission. It is not conducive to the application of automatic continuously variable speed locomotives with large displacement

Embodiment Construction

[0065] As shown in Figure 2, a synchronous conversion type continuous stepless transmission mechanism provided by the present invention is composed of a driving pulley set 40, a driven pulley set 50, a connecting frame 60 and a belt 70;

[0066] As shown in Figures 3 and 4, the driving pulley set 40 at least includes a first positioning pulley 42 defined on a drive shaft 41, and a first inner sliding sleeve 43 is nested therein. The first movable pulley 44 linked by the inner sliding sleeve 43 is sleeved with a back pressure plate 46 limited by a limiting sleeve 45, and a sliding seat 47 connected with the first movable pulley 44 is set. A plurality of Puli beads 440 are installed between the sharp plate 44 and the back pressure plate 46, and one end of the first inner sliding sleeve 43 is provided with more than one torsion groove 430, and each torsion groove 430 runs through a drive shaft respectively. The shaft 41 is combined with the interlocking toggle pin 48;

Abstract

A continuous stepless variable-speed mechanism of synchronous conversion type consists of a driving Pli disc set, a driven Pli disc set, a connection frame and belt. The said mechanism uses said driving and driven sets to generate radial motions and axial motion through connection frame and belt as well as some components then utilizes generated radial and axial motion to provide power transmission and stable gear ratio.

Description

technical field [0001] The invention relates to a synchronous conversion type continuous stepless speed change mechanism which can improve the efficiency of power transmission, the speed ratio of the speed change is more stable, and the service life of the belt is long. Background technique [0002] As shown in Figure 1, the existing continuously variable speed CVT mechanism includes a driving disc group 10, a passive disc group 20 and a transmission belt 30; 11. Relying on a backing plate 12, as the rotating speed of the drive shaft 13 increases, the centrifugal force increases, pushing a movable plate 14 to axially displace in the direction of the positioning plate 15 on the driving shaft 13, reducing the distance between the movable plate 14 and the positioning plate 15 , and make the drive belt 30 sleeved on the movable disc 14 and the positioning disc 15 change the nesting position from the inside to the outside, and the action disc 21 of the passive disc group 20 is or...
