摘要： A method is provided for the control of the state of engagement of a damper clutch arranged in association with a vehicle engine, which has a fuel cut mechanism for suspending a supply of fuel during a decelerated operation, to permit connection between an input member and an output member in a torque converter arranged on an output side of the engine. Upon detection of a decelerated operation of the engine, the damper clutch is controlled to bring the input member and output member into a desired state of engagement. Here, the damper clutch is first released for a predetermined time and is then moved to an engaged side. Next, the damper clutch is feedback-controlled into a desired slip state so that the input member and the output member are allowed to rotate with a desired difference in revolution speed therebetween. A system for practicing the method is also described.

摘要： The present invention relates to a power transmission system for a vehicle of the type in which front and rear wheels are driven by a sole engine. In order to control the distribution of drive torque produced by the engine to front wheel side and rear wheel side of the vehicle according to a difference in rotational speed between both sides and in relative rotational direction between both sides, the power transmission system includes an oil pump adapted to be driven by a first rotational shaft which transmits a driving torque from an engine to front wheels of the vehicle and a second rotational shaft which transmits the driving force to rear wheels of the vehicle. The oil pump produces an oil pressure proportional to the difference in rotational speed and has at least two ports. A clutch mechanism couples the rotational shafts with each other by the discharge pressure of the oil pump and, the clutch mechanism is disposed between the rotational shafts. An oil pressure control system controls the discharge pressure fed from the oil pump to the clutch mechanism to adjust the coupling force of the clutch mechanism in accordance with the difference in the relative rotational direction between the pair of rotational shafts.

摘要： In a power transmission apparatus for use in a vehicle of the type in which its front and rear wheels are driven by the same engine, a first rotary shaft transmitting drive force to the front wheels and a second rotary shaft transmitting drive force to the rear wheels are coupled to each other through a hydraulic oil pump which is driven according to the rotation speed difference between the first and second rotary shafts and delivers hydraulic oil of an amount corresponding to the rotation speed difference. The pressure of hydraulic oil delivered from the pump is controlled by hydraulic control means so as to automatically change over between the two-wheel drive mode in which the front or rear wheels only are driven and the four-wheel drive mode in which both the front and rear wheels are driven.

摘要： A power transmission includes two piston-type actuators for selectively engaging and releasing their associated clutches. Each of the actuators is designed in such a way that in order to compensate a centrifugal hydraulic pressure to be developed in a working fluid chamber by a remaining hydraulic fluid upon release of the clutch, a centrifugal hydraulic pressure chamber is formed on the side opposite to the working fluid chamber relative to a piston and a centrifugal hydraulic pressure equal to the centrifugal hydraulic pressure in the working fluid chamber is produced in the centrifugal hydraulic pressure chamber. A partition forming the centrifugal hydraulic pressure chamber also serves as a cylinder forming the working fluid chamber of the other actuator.
