Abstract

The invention relates to a continuous variable phase transmission mechanism of interruptable reverse variable speed planetary gear trains, wherein the continuous variable phase transmission mechanism mainly comprises planetary gear trains, a power input wheel, a power output shaft, gear rings, clutches and an integrated power transmission frame; each planetary gear train mainly comprises a sun gear, a planetary gear and a planetary gear frame; the planetary gear train I inputs power from outside and adjusts phases of an input / output shaft; the planetary gear train II outputs power and has the functions of adjusting a transmission ratio to change speed and emergently interrupting power transmission; simultaneously, by utilizing connection and disconnection of the clutch I, a certain fixed transmission ratio of power transmission and the power interruption function are realized; locking and unlocking of the planetary gear train II is realized through the clutch II; an electric control unit collects angular speed phase sensor signals of an input / output part and operates, and then outputs signals to a worm driven by an executor motor; and the worm drives the turbine to rotate, so that input / output phases are adjusted. According to the invention, the structure is compact; the power transmission is interruptable; the transmission ratio is variable in two-stage; input / output rotation directions are variable; phases are continuous and adjustable, 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...
