Abstract

The invention discloses a multi-path driving continuous variable transmission for a planetary gear. The multi-path driving continuous variable transmission for the planetary gear is characterized in that one or more than one set of planetary gear mechanism is connected with a rotation speed controller or a transmission, so as to form two or more than two intermediate transmission paths with different transmission ratios; the transmission or the rotation speed controller selects the transmission ratio to control a transmission path with a large transmission ratio or a rotation speed of a transmission path or a rotation component which is idle in a transmission process according to input power, an output resistance torque, a rotation speed and variation of control requirements, so that continuous variable transmission and torque variation of the rotation speed of an input rotation torque and a rotation torque of the planetary gear mechanism can be realized; furthermore, a transmission or auxiliary devices, such as a variable gear, a clutch, a locking mechanism and a one-way clutch can be additionally arranged in the transmission path to change the transmission characteristics of the transmission path, so that the large speed and torque variation range of the transmission can be obtained by changing the transmission ratio. The multi-path driving continuous variable transmission provided by the invention has the advantages of simple structure, high transmission efficiency, large transmission power and easiness in maintenance.

Description

technical field [0001] The present invention relates to a speed changer, in particular to a method of steplessly controlling the rotational speed of the transmission path with a larger transmission ratio among two or more transmission paths of a planetary gear transmission mechanism by using a suitable speed changer to realize the transmission ratio of the planetary gear mechanism to the input torque. infinite change. technical background [0002] Now continuously variable speed is the goal that the automobile industry, electric power industry and many other industries have been longing for. The current hydraulic automatic transmission and electronically controlled continuously variable transmission have made great progress to a certain extent, but due to: 1. Hydraulic automatic transmission The transmission ratio is discontinuous, and the transmission efficiency is low, and the power performance and fuel economy are not ideal. 2. Electronically controlled continuously vari...
