    摘要： A slip control mechanism comprises a throttling path with a cross-sectional area variable according to the relative displacement of an output element of a torque converter and an output shaft. The throttling path is in communication via a fluid passage with a disengagement chamber opposing one side of a friction clutch. The other side of the friction clutch faces an engagement chamber. The disengagement chamber and the engagement chambers are so arranged as to control slippage of the friction clutch by pressure balance therebetween. The throttling path is formed in a specific geometry which assures moderate changes in the pressure balance between the disengagement chamber and engagement chamber in an intermediate throttling range. In the preferred construction, the throttling path is so constructed that the rate of change of the throttling cross-sectional area satisifes the inequalityd.sup.2 S/dx.sup.2 .gtoreq.whereS is the cross-sectional area of the throttling path, andx is the relative displacement of the output element of the torque converter and the output shaft.

    摘要： A torque converter having an engine-driven pump impeller fastened to an input shell and a fluid-driven turbine runner mounted on an output shaft is equipped with a fluid-operated lockup clutch for providing a direct mechanical drive between the input shell and the output shell. The lockup clutch is maintained in a slipping engagement condition in an intermediate speed range. This slipping engagement is controlled by a variable fluid passage whose opening size is determined by an axial position of the turbine runner relative to the output shaft. The turbine runner is rotatable and axially movable relative to the output shaft. The turbine runner and the output shaft have, respectively, flanges which rotates side by side. There are formed, between the flanges, a plurality of pockets which are circumferentially arranged. Each pocket has contoured surfaces, and confines a ball. Each set of the ball and pocket is so formed as to control the opening size of the variable fluid passage by causing the turbine runner to move axially when the turbine runner rotate relative to the output shaft.

    摘要： A lock-up control device in which a pulse train is generated which has a duration which increases as the vehicle speed decreases. A counter generates a period indicative signal indicative of a current period of the pulse train. A memory stores the period indicative signal for a preceding period. An adder generates an adder signal indicative of the addition of a preset value to the period indicative signal stored in the memory. A comparator compares the adder signal with the period indicative signal generated by the counter and generates a comparator signal when the former is larger than the latter. A flip-flop generates a flip-flop signal when the comparator signal occurs under the presence of a lock-up signal. An AND gate provides a lock-up release signal when said flip-flop signal occurs irrespective of the presence of the lock-up signal.

    摘要： A countershaft gear transmission is disclosed wherein a plurality of main gears including a first main gear and a second main gear rotatably mounted to a main or output shaft, a countershaft drivingly connected to an input shaft has counter gears in constant engagement with the plurality of main gears and wherein when a low gear ratio is established the first main gear transfers power from the countershaft to the main shaft and when a high gear ratio is established the second main gear transfers power. The first main gear is formed on an outer race of a one-way clutch whose inner race is free to rotate on the main shaft. A synchronizer is coupled with the main shaft for coupling the inner race of the one-way clutch with the main shaft in all of the forward gear ratios. A disc clutch is coupled with the main shaft for coupling said second main gear with said main shaft in the high gear ratio.
