Automatic gear for motor vehicle e.g. passenger car, has brakes and clutches whose selective intervention causes different transmission ratios between drive and output shafts that are connected with sun and internal gears of planetary sets

摘要

The gear has brakes (06, 04, 05, 03) and clutches (16, 36, 34) whose selective intervention causes different transmission ratios between drive and output shafts (1, 2). The shafts (1, 2, 4) are connected with sun and internal gears of planetary sets (P3, P1, P2). Shafts (6, 3) are connected with bars of the sets (P1, P3), and the shafts (3, 4) by the clutches (36, 34). The shafts (4, 5) are connected with a housing by the brakes.
