The invention belongs to the technical field of transmissions, and particularly relates to a stepless speed change mechanism and a power assembly. The stepless speed change mechanism comprises a first planetary gear set and a second planetary gear set, a first gear ring of the first planetary gear set is connected with a second planet carrier of the second planetary gear set, and the stepless speed change mechanism further comprises a first input end; a second input; an output end connected with the first planet carrier; a first clutch arranged between the first planet carrier and a second gear ring; a second clutch arranged between the first planet carrier and a first sun gear; a first brake matched with the second gear ring; and a second brake which is configured to control the second planet carrier and the first gear ring to be static or allow the second planet carrier and the first gear ring to rotate freely. The stepless speed change mechanism is simple in structure, power input by the two input ends can be efficiently balanced, various continuous speed changes are achieved, large torque is achieved when the low rotating speed is output, and the wide application range is achieved.

    本发明属于变速器技术领域,具体包括一种无级变速机构及动力总成。无级变速机构包括第一行星齿轮组、第二行星齿轮组,第一行星齿轮组的第一齿圈与第二行星齿轮组的第二行星架相连,并且无级变速机构还包括:第一输入端;第二输入端;输出端,输出端与第一行星架相连;第一离合器,第一离合器设置在第一行星架和第二齿圈之间;第二离合器,第二离合器设置在第一行星架和第一太阳轮之间;第一制动器,其与第二齿圈配合;第二制动器,其配置成能够控制第二行星架及第一齿圈静止或允许其自由转动。该无级变速机构结构简单,能够高效平衡两个输入端输入的动力,实现多种连续变速,且在输出低转速时具有较大扭矩,具有广泛的适用范围。
