Abstract

The invention belongs to the technical field of transmissions, and specifically includes a double-row transmission mechanism and a power assembly. The double-row transmission mechanism includes a housing; the first planetary gear set, the first sun gear and the first ring gear in the first planetary gear set keep rotating in the same direction; the second planetary gear set, the first sun gear in the second planetary gear set The second sun gear is connected with the first ring gear in the first planetary gear set; the input end; the output end; the first control unit, the first control unit includes a first driven element connected with the housing, and a first driven member connected with the first ring gear The second passive element, and the first active element connected to the first planet carrier; and the second control unit, the second control unit includes a third passive element connected to the housing, and a fourth passive element connected to the second planet carrier , and the second active member connected with the second ring gear. The double-row speed change mechanism has simple structure, wide variation range of transmission ratio, simple control logic, uninterrupted power transmission when shifting gears, little wear of each component, and wide application range.

Description

technical field [0001] The invention relates to the technical field of transmissions, and in particular provides a double-row transmission mechanism and a power assembly. Background technique [0002] With the continuous progress and development of society, people pay more and more attention to the protection of the environment. Industries with serious pollution emissions have been upgraded one after another and gradually transformed into green and environmental protection industries. At present, one of the exploration directions of the vehicle industry is new energy electric vehicles. New energy electric vehicles use electric energy to replace fuel, and can achieve zero exhaust emissions during driving, which has outstanding environmental protection advantages. In addition, new energy electric vehicles use electric motors instead of traditional engines. Electric motors have the characteristics of high speed, large starting torque, and stable operation, which can effective...
