Gear combination structure for powertrain of motor vehicle e.g. car, has sub-planet pinion carrier provided with holes for receiving planetary gear-storing bolt, and center portion formed between sub-planet pinion carriers

摘要

The structure (1) has a differential gear box (2) and planetary stage (3) that are provided with several sub-planet pinion carriers (6-8) and torque-proof planet pinion carrier (5). A center portion is formed between sub-planet pinion carriers (6,7), and sub-planet pinion carrier (8) is provided with holes for receiving planetary gear-storing bolt (19). The holes are concentrically arranged in surface area, into which sub-planet pinion carrier is incorporated.
