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 prevent the temperature of lubrication oil from rising, by providing an oil receiving section having a lubrication oil discharge port, separate from a main oil reservoir. CONSTITUTION:In a chain drive type transfer device composed of a drive gear 10, a driven gear 11 and a chain 12, the lower section of a lubrication oil chamber 17 defined by a case member 14 is formed therein with a main oil reservoir 19, and further, an oil receiving section 21 defining therein an auxiliary oil reservoir 20 is formed in the center section of the lubrication oil chamber 17 which is the position where no agitation is made. Therefore, since lubrication oil is pooled in the auxiliary oil reservoir, the amount of lubrication oil to be agitated becomes less so that the agitation resistance may be reduced and it is possible to prevent the temperature of lubrication oil from rising.

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 improve control accuracy ever so better, by making a shift valve restrict the feed of a hydraulic medium to a first frictional engaging device till the lapse of time for selection from a second shift step to a first shift step reaches to a hour calculation time. CONSTITUTION:A timer 132 and a time calculating device 134 to calculate the fixed time related to the detected car speed of a car speed sensor 62 both are connected to a down shift detecting device 130 from the third speed to the second, while an underlap controlling solenoid valve 78 is controlled so as to restrict the feed of a hydraulic medium to a first frictional engaging device till the time measured by the said timer 132 reaches to a hour calculation time. With this constitution, in regard to control over an underlap period, influences of timing variations in time of transfer of controlling hydraulic pressure and variations in spring force of a control valve or the like are eliminable so that highly control accuracy is securable.

摘要： PURPOSE:To prevent the occurrence of a shock and a rise in an engine in time of selection to shift steps, by making a passage sectional area smaller till hydraulic pressure in a high-speed frictional engaging device reaches to the reference one. CONSTITUTION:A solenoid valve 102 is installed in a discharge oil passage 94, then a hydraulic sensor 44 is installed in a high-speed step clutch 24, and output out of the hydraulic sensor 44 is inputted into a central processing unit 48, while a solenoid valve 70 is controlled so as to make a passage sectional area of the discharge oil passage 94 smaller till hydraulic pressure in the high-speed step clutch 24 reaches to the reference one as well as to make the passage sectional area of the discharge oil passage 94 larger after the hydraulic pressure reaches the reference one. With this constitution, an overlap period comes to the length corresponding to the high-speed step of main transmission so that a shift shock and a rise in an engine in time of selection of an auxiliary transmission from the lowspeed step to high-speed one are preventable irrespective of a shift step of the main transmission.

摘要： PURPOSE:To enhance engaging capability and durability of a fluid type torque converter and as well to enable the torque converter to have a large capacity of transmission torque, by providing, in the torque converter, a direct coupling clutch which comprises an engagement initiating friction surface having a large coefficient of sliding friction and a large heat capacity, and an engagement completing friction surface having a large coefficient of static friction and a large surface-pressure proof strength. CONSTITUTION:A gap B between a first friction surface 11 and a second friction surface 61 upon disengagement of a clutch is so formed that is made narrower outwards. The outer part of a friction member 7 disposed in this gap if formed with a first friction member 71 having a large efficiency of heat radiation and a large coefficient of dynamic friction, and the inner part of the friction member 7 is formed with a second frictional member 72 having large coefficient of static friction and a large surface-pressure proof strength. With this arrangement, the outer periphery of the second friction surface 61 is, at first, frictionally engaged with the friction member 71 when operating medium oil flows in the direction of arrows A so that a disc 6 is moved toward a front cover 1. The inner peiphery 62 of the friction member 61 is frictionally engaged with the frictional member 72 when the engagement is completed, so that they are opposed together under high surface-pressure. With this arrangement, engaging capability and durability of the clutch are enhanced and the capacity of transmission torque may be also increased.
