Abstract

A continuous variable phase transmission mechanism of a planetary gear train with interruptible reversing and variable speed, mainly including a planetary gear train, a power input wheel, a power output shaft, a ring gear, a clutch and an integrated power transmission frame. The planetary gear train mainly includes a sun gear, a planetary The first planetary gear system inputs power from the outside and adjusts the phase of the input and output shafts. The second planetary gear system outputs power. It has the function of adjusting the transmission ratio for speed change and emergency power transmission. Whether the clutch is engaged or not, At the same time, a certain fixed transmission ratio and power interruption function of power transmission are realized. Clutch 2 realizes whether the planetary gear train 2 is locked or not. The gear motor drives the worm to drive the turbine to rotate to adjust the input and output phases. The invention has the characteristics of compact structure, interruptible power transmission, two-stage variable transmission ratio, variable input and output rotation directions, continuously adjustable phase and the like.

Description

technical field [0001] The invention relates to a power transmission mechanism, in particular to a double planetary gear train transmission mechanism with interruptible power transmission, two-stage variable transmission ratio, variable output rotation direction and continuously adjustable phase. Background technique [0002] With the advancement of technology, a large number of internal combustion engines with dual working modes have appeared, and the integration requirements for the variable phase and transmission ratio functions of the valve train have been put forward. Other systems that require variable phase and transmission ratio in the power transmission process are also required It is constantly increasing, and some also require the function of switching the direction of rotation. During the use of a power unit such as a vehicle, it often occurs that the power unit cannot be stopped due to a failure. If the braking system performance is poor or fails at the same tim...
