    摘要: A power transmission device for four wheel drive vehicle includes a differential motion limiting device, for limiting differential motion of a center differential device, which is made up by a wet-type frictional clutch and a hydraulic actuator. Under running condition, the frictional clutch is engaged by certain engaging force, and considering frictional coefficient of roads, the clutch is engaged with some slips so that torque distribution to front and rear wheels becomes even (50:50), then torque is distributed from the center differential device to front and rear wheels. The line pressure is applied to the hydraulic actuator through a regulator valve. In normal running condition, the regulator valve reduces the line pressure pre certain ratio, the reduced pressure is applied to the hydraulic actuator. In the case the manual valve being shifted to R range or low speed position, the regulator valve is switched to apply the line pressure directly to the hydraulic actuator. In the case of the manual valve being shifted to a low speed position, then from the low speed port of the manual valve, the line pressure is applied to a modulator valve where the line pressure is modulated, and applied to a back pressure port of a primary regulator valve to boost the line pressure up to certain volume.

    摘要: A pressure regulating valve in a hydraulic control system for an automatic transmission according including a pressure regulating unit having a spool made slidable in a valve sleeve 10. An electromagnetic unit for causing a hollow core (or stator) is provided to attract a plunger (or movable element) arranged on a push rod communicating with the spool. The spool is moved by a spool moving mechanism in a direction to increase the flow from an input port to an output port to thereby raise an output pressure from an output port when the output pressure is lowered by a leakage. The spool position is controlled to control the output pressure in accordance with a balance among a spring force of spring means fitted in the valve sleeve, a feedback force resulting from the output pressure, and an electromagnetic attraction to be established in response to an electric signal provided to the electromagnetic unit having the hollow core and the plunger. In another embodiment, an input pressure feedback port is provided in the valve sleeve, and spool position control is additionally dependent upon an input pressure feedback force provided to the input pressure feedback port.

    摘要: Provided is a power transmission device for four-wheel drive vehicles of both the full-time type and part-time types, wherein a wet multiple-disc clutch is mounted in a ring gear covering the front-wheel differential gear and arranged coaxially with the differential gear. The wet multiple-disc type clutch is engaged by means of a hydraulic actuator in which a plurality of pistons are arranged in series. Hydraulic pressure is fed into oil chambers formed by the pistons through individual or common oil passages. The wet multiple-clutch constitutes a differential motion limiting device for stopping or limiting the differential motion of a center differential gear for the full-time four wheel drive, or constitutes a rear wheel drive switching unit for engaging and disengaging the power transmission between the ring gear mount casing and the transfer unit.

The control unit has a base board on which a plurality of elements are arranged, including a microcomputer containing an automatic transmission control program, and a position detecting switch whose detecting portion is connected to the microcomputer. The base board and the position detecting switch are disposed in a single case. The position detecting switch has a rotor and a plurality of non-contact sensors disposed on the base board. The microcomputer contains a learning control program for calculating and correcting any positional deviation in the rotational angle of the rotor with respect to each sensor on the basis of signals from the sensors corresponding to rotation of the rotor. Some of the elements on the base board are arranged outside the range of rotation of the rotor.
