and has no rotational speed 160 e since the output shaft 126 is rotating faster than stationary second driven gear 134 the second one way bearing 132 does not engage and the output shaft 126 freewheels inside of the second driven gear 134 in this stage the second drive gear 120 does not apply any torque to the output shaft 126 the third drive gear 122 is permanently attached to the input shaft 112 and has a rotational speed 160 f and limited torque that rotates the third driven gear 128 however the third hydraulic clutch 130 is currently not activated and therefore the third drive gear 122 also does not apply torque to the output shaft 126 the high gear ratio of driven gear 138 to drive gear 116 provides high torque to the output shaft 126 for pushing the first hydraulic clutch 114 can also be used as an inching clutch for starting and fine positioning however any of the other clutches may be also used for inching control fig3 b shows how the transmission system 14 operates during a transition from first drive gear 116 to the second drive gear 120 the second hydraulic clutch 118 is activated causing input shaft 112 to rotate second drive gear 120 with rotational speed 160 d in this example the first hydraulic clutch 114 is shown still activated and the third hydraulic clutch 130 is still not activated however the first hydraulic clutch 114 may be released sometime after the second hydraulic clutch 118 is activated the second drive gear 120 rotates the second driven gear 134 faster.
