摘要： PURPOSE:To smooth down-shift operation by interposing a clutch and a one-way clutch in two speed change gear sets for transmitting torque of an output gear of the top step speed change gear set to an output shaft. CONSTITUTION:A superoverdrive step gear train 30 for transmitting torque of the fifth speed output gear 15b to an output shaft 5 through a hydhaulic clutch 37 is disposed in the rear of the fifth speed gear set 15. Further there is provided a down-shift gear set 40 for superoverdrive operation, which transmits torque of the fifth speed output gear 15b to the output shaft 5 through a one-way clutch 41. Down-shift operation cen be automatically conducted by on-off operation of the clutch.

摘要： PURPOSE:To make a gear type transmission in a compact size by adding a small-sized speed up gear set to which torque of an output gear of the top step is input to be transmitted to an output shaft of a transmission. CONSTITUTION:A superoverdrive step sixth speed gear train 30 to which only torque of the fifth speed output gear 15b is input is disposed in the rear of the fifth speed gear set 15. When the fourth clutch 37 is engaged with the sixth speed output gear 35b by switching a change lever, torque of the fifth speed output gear 15b is transmitted to an output shaft 5. Accordingly the gear train 30 transmits only torque of the fifth speed output gear to the output shaft 5 so as to make a transmission in a compact size.

摘要： PURPOSE:To reduce the number of parts of reversing output transmission structure, by a method wherein a gear for PTO shift, normally engaged with the fixed gear of an input shaft, is loosely engaged with a shaft for a PTO system, and is used as a back gear for a transmission mechanism for running shift. CONSTITUTION:A third shaft 14 for a PTO system is provided with a first transmission gear 20, a second transmission gear 21, and a third transmission gear 22, and the third gear 22 is normally engaged with a fixed gear 17 of the first shaft 12 for input. A clutch part Cb, coupled to a clutch part Ca of a first transmission gear 20, is formed to the side of the gear 22. In this constitution, the third transmission gear 22 additionally serves as the back gear of a first gear shifting mechanism G situated between the first shaft 12 and a second shaft 13 for a running system output, and a power from the second gear 16 is fetched as a reverse power through the third transmission gear 22 by shift control of a second shift gear 19. This constitution enables reduction of the number of parts.

摘要： PURPOSE:To shorten the longitudinal length of a transmission by arranging a high/low speed switching transmission and a main transmission in parallel then arranging an advance/back switching device and a sub-transmission while adjoining respectively to the front and rear of the former transmissions. CONSTITUTION:An output shaft 16, a counter shaft 22 and an output shaft 23 to a sub-transmission device 6 are arranged in parallel in a transmission case 21 while a high speed hydraulic clutch 24 and a low speed hydraulic clutch 25 are coupled to the output shaft 16. Furthermore, a main transmission 5 having synchromesh mechanisms 41, 42 sandwiching the counter shaft 22 is provided. At the input side of the main transmission 5, an advance input gear 17 and a back input gear 18 are fitted idly over the output shaft 16 disposed in parallel with the input shaft 13 thus forming an advance/back switching device 3. Furthermore, in a case 42 coupled to the rear end of said case 21, a sub- transmission 6 is constructed with gears 46-52 arranged on the output shaft 23, the counter shaft 44 and the output shaft 45 and the clutch gears 53, 54.
