FIELD: machine building.SUBSTANCE: automobile transmission gear box includes four in-series located planetary rows (P1a, P2a, P3a, P4a; P1b, P2b, P3b, P4b), six connecting links (S1a, S2a, S3a, S4a, S5a, S6a; S1b, S2b, S3b, S4b, S5b, S6b) and drive assembly (11a; 11b), which allow incorporating nine forward speeds (V1a-V9a; V1b-V9b). Drive assembly (11a; 11b) is inseparably attached to sun wheel (P21a; P21b) of the second planetary gear (P2a; P2b) and carrier (P42a; P42b) of the fourth planetary gear (P4a; P4b). Driven assembly (12a; 12b) is inseparably attached to carrier (P32a; P32b) of the third planetary gear (P3a; P3b).EFFECT: compact device design with a large number of forward speeds.15 cl, 6 dwg |
