The invention belongs to the technical field of transmissions, and particularly relates to a dual-power speed regulating mechanism and a power assembly. Wherein the dual-power speed regulating mechanism comprises a first planetary gear set and a second planetary gear set, and a second gear ring of the second planetary gear set is fixedly connected with a first planet carrier of the first planetary gear set; the first input end is connected with the first sun gear; the second input end is connected with the second sun gear; the output end is connected with the first planet carrier or the second gear ring; the first brake is configured to control the first gear ring to be static or allow the first gear ring to rotate freely; the second brake is configured to control the second planet carrier to be static or allow the second planet carrier to rotate freely; and the output end outputs various rotating speeds through cooperative control of the first brake and the second brake. The dual-power speed regulating mechanism is simple in structure, can provide large torque when outputting a low rotating speed, and can provide a high rotating speed upper limit.
本发明属于变速器技术领域,具体包括一种双动力调速机构和动力总成。其中双动力调速机构包括第一行星齿轮组、第二行星齿轮组、第二行星齿轮组的第二齿圈与第一行星齿轮组的第一行星架形成紧固连接;第一输入端与第一太阳轮相连;第二输入端与第二太阳轮相连;输出端与第一行星架或第二齿圈相连;第一制动器,第一制动器配置成能够控制第一齿圈静止或允许其自由转动;第二制动器,第二制动器配置成能够控制第二行星架静止或允许其自由转动;通过第一制动器和第二制动器的配合控制以使输出端输出多种转速。该双动力调速机构结构简单,输出低转速时能够提供较大扭矩,并且能够提供较高的转速上限。
