CONTINUOUSLY VARIABLE TRANSMISSION AND A WORKING MACHING INCLUDING A CONTINUOUSLY VARIABLE TRANSMISSION

摘要

Continuously variable transmission (1) including a variator unit (2) having a variator input shaft (4) and a variator output shaft (6), and first, second and third planetary gear sets (8, 10, 12). The first and second planetary gear sets (8, 10) are arranged together and including each a first member (14a, 16a) being operatively connected to a common transmission input shaft (20) and a second member (14b, 16b) being operatively connected to a common output shaft (22), each of said first and second planetary gear sets (8, 10) further including a third member (14c, 16c). The third planetary gear set (12) having a first, second and third member (18a, 18b, 18c). The variator input shaft (4) is operatively connected to said third member (16c) of said second planetary gear set (10) and the variator output shaft (6) is operatively connected to the third member (14c) of the first planetary gear set (8). The first member (18a) of the third planetary gear set (12) is operatively connected to the variator output shaft (6). The second member (18b) of the third planetary gear set (12) is selectively connectable to the third member (16c) of the second planetary gear set (10) and selectively connectable to the transmission housing (26). The third member (18c) of the third planetary gear set (12) is operatively connected to a transmission output shaft (30). The common output shaft (22) is selectively connectable to the transmission output shaft (30).
