| 摘要 |
The invention relates to a multi-speed gearbox, comprising an input shaft (1) and an output shaft (2),arranged in a housing, three single-carrier planetary gears (P1, P2, P3), seven rotating shafts (1, 2, 3, 4, 5, 6, 7) and six switching elements (03, 04, 14, 17, 36, 56), which comprise brakes and clutches, the selective engagement of which generates seven forward gears and one reverse gear. Input drive is achieved by means of a shaft (1), in permanent connection to the sun wheel of the first planet gear set (P1), output drive is achieved by means of a shaft (2), connected to the internal gear wheel of the second planet gear set (P2) and the internal gear wheel of the third planet gear set (P3), a shaft (3) is permanently connected to the internal gear wheel of the first planet gear set (P1), a shaft (4) is permanently connected to the planet carrier of the second planet gear set (P2) and the planet carrier of the third planet gear set (P3), a shaft (5) is permanently connected to the planet carrier of the first planet gear set (P1), a shaft (6) is permanently connected to the sun wheel of the second planet gear set (P2), a shaft (7) is permanently connected to the sun wheel of the third planet gear set (P3) and the planet gear sets (P1, P2, P3) are coupled to shafts (1, 2, 3, 4, 5, 6, 7) and switching elements (03, 04, 14, 17, 36, 56). |
