Ten gear transmission

摘要

Transmission (10), comprising: a gear housing (50); an input element (12); an output element (22); a first, second, third and fourth planetary gear set (14, 16, 18, 20), which each include a sun gear (14c, 16a, 18c, 20c), a ring gear element (14a, 16c, 18a, 20a) and a planet wheel carrier element (14b, 16b, 18b, 20b); wherein said input member (12) constantly for common rotation with the planet gear carrier element (16b) of the second planetary gear set (16) is connected and the output element (22) constantly for common rotation with the planet gear carrier element (20b) of the fourth planetary gear set (20) is connected; a first connecting element (44), the the sun gear (14c) of the first planetary gear set (14) is permanently connected with the sun gear (16a) of the second planetary gear set (16), a second connecting element (48), which the planet gear carrier element (14b) of the first planetary gear set (14) is permanently connected with the planet gear carrier element (18b) of the third planetary gear set (18) and with the ring gear element (20a) of the fourth planetary gear set (20), a third connecting element (52), which the ring gear element (16c) of the second planetary gear set (16) is permanently connected with the sun gear (18c) of the third planetary gear set (18), by means of six torque transmission mechanisms (24, 26, 28, 30, 32, 34), wherein the first, second, third and fourth torque transmitting mechanism (24, 26, 28, 30) by means of the six torque transmission mechanisms (24, 26, 28, 30, 32, 34) couplings, and wherein the fifth and sixth torque transmission mechanism (32, 34) by means of the six torque transmission mechanisms (24, 26, 28, 30, 32, 34) brakes are, wherein the first torque transmission mechanism (24) is selectively engageable, the input element (12) with the sun gear (20c) of the fourth planetary gear set (20) to connect the second torque transmission mechanism (26) is selectively engageable, the sun gear (18c) of the third planetary gear set (18) with the sun gear (20c) of the fourth planetary gear set (20) to connect the third torque transmission mechanism (28) is selectively engageable, the ring gear element (18a) of the third planetary gear set (18) with the sun gear (20c) of the fourth planetary gear set (20) to connect the fourth torque transmitting mechanism (30) is selectively engageable, the ring gear element (18a) of the third planetary gear set (18) with the planet gear carrier element (20b) of the fourth planetary gear set (20) to connect the fifth torque transmission mechanism (32) is selectively engageable, the ring gear element (14a) of the first planetary gear set (14) with the gear housing (50) to connect the sixth torque transmission mechanism (34) selectively can be inserted is around the sun gear (14c) of the first planetary gear set (14) with the gear housing (50) to connect the six andthe transmission of torque by means of mechanisms (24, 26, 28, 30, 32, 34) are selectively in three-compound combinations can be inserted, in order to ten forward rotational speed ratios and a backward rotational speed ratio between the input element (12) and the output element (22) to produce.
