摘要： A direct coupling clutch being assembled within a casing of a fluid coupling having an impeller mounted on the casing and a turbine rotatably supported within the casing. The direct coupling clutch includes a piston slidably mounted on a turbine hub in axial direction for engaging with and disengaging from a front cover of the casing and a unitary assembled damper device provided between the hub and piston. The damper device includes a driven plate consisting of two annular guide plates positioned concentrically with each other, an annular drive plate interposed between the guide plates and being slidable with respect to the guide plates in circumferential direction and two sets of coil springs arranged in double rows along two concentric circles between the guide plates and being compressed by relative rotation of the drive and driven plates. The damper device is unitary assembled by securing the guide plates with each other and is capable to fixedly connect to one member of either turbine hub or piston by one plate of either drive plate or driven plate and to axially slidably connect to another member by another plate.

摘要： A control system for an automatic transmission includes a clutch adapted to be applied when a forward running range is selected, for transmitting the rotation of an engine to a speed change unit. A hydraulic servo applies the clutch responsive to feed of an oil pressure and a control unit controls the oil pressure fed to the hydraulic servo. The control unit brings the clutch into a substantially released state by lowering the oil pressure of the hydraulic servo if the stop state of a vehicle is detected by a stop state detector and applies the clutch if the stop state of the vehicle is not detected with the clutch released. The oil pressure fed to the hydraulic servo is raised according to a second mode when the accelerator pedal is depressed, in preference to a first mode in which a brake pedal is released, if the accelerator pedal is depressed when the stop state of the vehicle is not detected because the accelerator pedal is released so that the engagement of the clutch has not started.

摘要： A control system for an automatic transmission includes a first frictional engagement element and a second frictional engagement element; and a first hydraulic servo for controlling the application/release of the first frictional engagement element and a second hydraulic servo for controlling the application/release of the second frictional engagement element. A regulator valve regulates the oil pressure to the first hydraulic servo.

摘要： A control system is provided for servo hydraulic pressure in an automatic transmission. Upon downshifting, one of first and second frictional engagement devices is released while the other is engaged. A directional control valve is provided to feed or drain servo hydraulic pressure to selectively engage or release the first and second devices. The hydraulic pressure is regulated by a pressure regulator under the control of an electronic control unit. Detectors are also provided to determine input rotation and torque, respectively. The regulator is interposed between the directional control valve and the engaged device. The regulator is controlled to maintain the servo hydraulic pressure at a predetermined value under the control of the electronic control unit until predetermined input rotation is detected and then to gradually raise the servo hydraulic pressure under the control of the electronic control on the basis of the value of input torque.

摘要： A control system in an automatic transmission for controlling the change-over of the three speed change patterns which are a speed change pattern having a cross gear ratio on a low speed side, a speed change pattern having a cross gear ratio on a high speed side and a speed change pattern having a normal gear ratio. According to this controlling system, when one of the three speed change pattern is selected based one a throttle opening and a vehicle speed, and when it is judged that the gear shift from a speed range in the present speed change pattern to a speed range in the selected speed change pattern falls under on of prohibited conditions, e.g., requiring engagement and/or disengagement of three or more frictional engaging elements for the gear shift, the gear shift is performed using a temporary speed change pattern (including the present speed change pattern) including a speed range not falling under the prohibited conditions. Thereafter, the pattern selection is repeated and the change-over between speed change pattern is performed under a gear shift condition not falling under the prohibited conditions.
