21. I . e . if the planetary gear housing is held still, conventional steering operation is retained. 22. There is no externally visible way to determine whether the transmission contains the straight-cut planetary gear set. 23. The significant development was the patented design of the first planetary gear unit applied to centrifugal equipment. 24. The Internal Combustion Engine is connected to the planetary gear carrier and not to any individual gear. 25. The planetary gear train also provides stability due to an even distribution of mass and increased rotational stiffness. 26. The load in a planetary gear train is shared among multiple planets, therefore torque capability is greatly increased. 27. The unique transmission houses the electric motors along with three different planetary gear sets and four traditional clutches. 28. The planetary gear housing features external gear teeth and can be rotated by a motor and worm gear. 29. For bicycles equipped with hub gears, the gear ratio also depends on the internal planetary gears within the hub. 30. The car had a newly designed carburetor and a planetary gear system which had two speeds; forward and reverse.
