摘要： PURPOSE:To maintain the superior drive feeling by permitting the difference of the speed change timing between a main speed change gear and a sub speed change gear to be adjusted, when the direction of the speed change of the main and the sub speed change gears is made reverse. CONSTITUTION:When each output of a shift position sensor 20, L/H position sensor 22, and a car-speed sensor 32 is input into a CPU 36, and each speed change of a main speed change gear 14 and a sub speed change gear 16 is made reverse, the difference of the speed change timing between the main speed change gear 14 and the sub speed change gear 16 can be adjusted. Then, the time interval between the time when one of the main speed change gear 14 and the sub speed change gear 16 is shifted-up and the time when the other is down- shifted can be properly separated and brought close to each other, and the generation of the time interval between the both speed change timings which deteriorates drive feeling can be obviated, and the superior drive feeling can be maintained.

摘要： PURPOSE:To prevent inadequate speed change of a main speed changer upon operating sub speed changer manually in the automatic speed change gear equipped with main and sub speed changers. CONSTITUTION:The main speed changer 14 is provided with first - fourth speed changing stages, which are switched automatically by the opening degree of a throttle or the like, while the sub speed changer 16 is provided with high- speed stage and low-speed stage which are switchable by manual operation. When the operating position of the sub speed changer 16 is switched from H (high speed) to L (low speed), an indicating speed change stage M1, operated before changing H L, is compared with the indicating speed change stage M2 after the change H L and in case M2

摘要： PURPOSE:To improve the durability of component parts by prohibiting a main speed change gear from becoming overdriven speed range while operating position for deciding speed range of a sub speed change gear remains in low speed range. CONSTITUTION:While the operating position for deciding speed range of a sub speed change gear 16 remains in low speed range, a main speed change gear 14 is prohibited from entering overdriven speed range. As a result, while the sub speed change gear 16 remains in low speed range, the main speed change gear 14 is kept away from entering overdriven speed range, hence, the maximum rotation speed of an output shaft of the main speed change gear 14 is limited to a proper value with the result that the durability of component parts of output shaft system of the main speed change gear 14 and input shaft system of the sub speed change gear 16 can be improved.

摘要： PURPOSE:To contrive to shorten the axial length of a twin clutch type speed change gear and to facilitate the setting of its change gear ratio by a structure wherein an input shaft, an output shaft and a counter shaft are arranged parallel to each other and at the same time speed change gears and adjusting gears are provided onto each of said shafts. CONSTITUTION:An input shaft 2, an output shaft 3 and a counter shaft 4 are arranged parallel to one another and yet a first clutch 5 is provided at the input shaft 2 and a second clutch 6 is provided at the counter shaft 4. Speed change gears 8 and 9 are provided onto the shaft 2 and speed change gears 14 and 15 are provided onto the shaft 3 and speed change gears 11 and 12 are provided onto the shaft 4. On the other hand, a second adjusting gear 17, which is loosely fit onto the output shaft 3, is engaged with the first adjusting gear 16 made integral with the input shaft 2 and with the third regulating gear 18 loosely fitted onto the counter shaft 4. Speed change is performed by selectively operating the first clutch 5, the second clutch 6 and synchromeshes 10 and 13.

摘要： PURPOSE:To enhance the response of a shift speed control valve, by setting at least one of positions for positioning a spool valve element, to a half-opening position where the spool valve element opens in part a predetermined port, so that the moving stroke of the spool valve element is made short. CONSTITUTION:A spool valve element 124 comprising a spool shaft 132 and a plurality of spool lands 134A, 134B, 134S having a partly increased diameter in the axial direction of the spool shaft 132, is slidably fitted in a cylinder bore 138 formed in a valve body 136. In comparison with a conventinal arrangement in which the spool valve element 124 is moved until it fully open an input port 139 or a discharge port 141, the stroke of the instant spool valve element 124 is set to such a degree that each port is opened in part, and therefore is made short, thereby it is possible to enhance the response of a spool valve 118.
