摘要： In a vehicular belt-driven continuously variable transmission, belt squeezing force is inhibited from becoming excessive and a safety factor, with respect to belt slip, of belt squeezing force applied to a transmission belt (48) is reduced to a value that is less than or equal to 1.5 by reducing a pressure receiving area (SOUT) of an output side hydraulic cylinder (46c). As a result, a centrifugal hydraulic pressure canceller chamber on a secondary pulley side (46) can be eliminated thus simplifying the structure of the vehicular belt-driven continuously variable transmission, while belt squeezing force can be appropriately controlled.

摘要： In a hydraulic control system for a transmission, line pressure Pl is adjusted in accordance with a second solenoid pressure Psls if the ratio of a first sheave pressure Pin with respect to a second solenoid pressure Psls is equal to or less than the gain α. If not so, the line pressure Pl is adjusted in accordance with the first sheave pressure Pin. Consequently, the gain η of the first sheave pressure Pin with respect to a first solenoid pressure Pslp at a first sheave pressure adjustment valve 16 and the gain α of a second sheave pressure Pout with respect to the second solenoid pressure Psls at a second sheave pressure adjustment valve 17 can be individually set while the line pressure Pl can be suppressed to the substantially requisite minimum in the entire control region.

摘要： A hydraulic control circuit that shuts off an oil passageway so that the ratio between the shift pressure and the belt clamping pressure is not caused to be in a predetermined relationship even when a speed change ratio control valve and/or a speed change ratio control valve are not supplying/discharging hydraulic oil. Therefore, even if the speed change ratio control valve and/or the speed change ratio control valve cease supplying/discharging the hydraulic oil, the action of a thrust ratio control oil pressure Pτ output from a thrust ratio control valve on a primary hydraulic cylinder is avoided. Thus, impairment of the continuity of control at the time of a shift of the continuously variable transmission is prevented.
摘要翻译：即使在变速比控制阀和/或变速比控制阀为...时，切断油路的液压控制回路也不会使变速压力与带夹紧压力之间的比例成为规定的关系不供应/排放液压油。因此，即使变速比控制阀和/或变速比控制阀停止供给/排出液压油，从主液压缸上的推力比控制阀输出的推力比控制油压Ptau的作用是避免。因此，防止无级变速器的变速时的控制连续性的损害。
