VEHICULAR AUTOMATIC TRANSMISSION

A vehicular automatic transmission includes a plurality of engagement devices (B1, B2, C1, C2, C3, C4) and a plurality of planetary gear sets (36, 38, 40). Each of the planetary gear sets (36, 38, 40) includes rotating elements (S1, S2, S3, CA1, CA2, CA3, R1, R2, R3). At least one of the rotating el...

Zusammenfassung:	A vehicular automatic transmission includes a plurality of engagement devices (B1, B2, C1, C2, C3, C4) and a plurality of planetary gear sets (36, 38, 40). Each of the planetary gear sets (36, 38, 40) includes rotating elements (S1, S2, S3, CA1, CA2, CA3, R1, R2, R3). At least one of the rotating elements (S1, S2, S3, CA1, CA2, CA3, R1, R2, R3) of one of the plurality of planetary gear sets (36, 38, 40) is coupled to one of the rotating elements (S1, S2, S3, CA1, CA2, CA3, R1, R2, R3) of another planetary gear set or one of the engagement devices (B1, B2, C1, C2, C3, C4), via a spline engagement portion (82). The rotating elements (S1, S2, S3, CA1, CA2, CA3, R1, R2, R3) other than the at least one of the rotating elements (S1, S2, S3, CA1, CA2, CA3, R1, R2, R3) coupled via the spline engagement portion (82) is coupled to another rotating element or a non-rotary member (18) directly or via one of the engagement devices (B1, B2, C1, C2, C3, C4). The at least one of the rotating elements (S1, S2, S3, CA1, CA2, CA3, R1, R2, R3) coupled via the spline engagement portion (82) is configured to be co-rotated with no torque transmitted via the spline engagement portion (82), when the automatic transmission is placed in a predetermined gear position as one of the plurality of gear positions.
