Embodiment Construction

[0030] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0031] It should be noted that, in the description of the present invention, terms such as "inner", "outer" and other indicated directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, rather than Nothing to indicate or imply that a device or element must have a particular orientation, be constructed, and operate in a particular orientation should therefore be construed as limiting the invention. In addition, the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and should not be construed as indica...

Abstract

The invention belongs to the technical field of transmissions, and particularly relates to a double-row speed change mechanism and a power assembly. The double-row speed change mechanism comprises a shell. A first sun gear and a first gear ring in the first planetary gear set keep rotating in the same direction; a second sun gear in the second planetary gear set is connected with a first gear ring in the first planetary gear set; an input terminal; an output terminal; the first control unit comprises a first driven part connected with the shell, a second driven part connected with the first gear ring, and a first driving part connected with the first planet carrier; and the second control unit comprises a third driven part connected with the shell, a fourth driven part connected with the second planet carrier, and a second driving part connected with the second gear ring. The double-row speed change mechanism is simple in structure, large in transmission ratio change range, simple in control logic, free of interruption of power transmission during gear shifting, small in abrasion of all parts and wide in application range.

Description

technical field [0001] The invention relates to the technical field of transmissions, and specifically 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 polluting emissions have been upgraded and transformed gradually 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 instead of 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. The electric motors have the characteristics of high speed, large starting torque, and stable operation, which can effectively improve the ...
