    摘要: Thrust force generated by a hydraulic actuator is absorbed in a attachment device for a four speed automatic transmission mechanism. When hydraulic pressure is applied to the hydraulic actuator to engage a third and a fourth clutches, pressing force from a piston works on a strut member situated between the third and fourth clutches as a compression force, while a force working on a drum member as a tension force, so that these forces are counterbalanced and absorbed in the attachment device. Consequently, one directional move of the attachment device is supported by a little force such as contacting a snap ring and a thrust washer to a clutch drum, on the other hand, another move of the attachment device is supported by a little force such as connecting the drum member and a big ring gear by a snap ring.

    摘要: A hydraulic control device which has a check valve controlling hydraulic pressure to a hydraulic actuator. Hydraulic pressure is selectively supplied to one of plural oil passages having different capacity orifices by a switching valve which switches high speed rotation mode and low speed rotation mode. A hydraulic power source and plural oil passages having different capacity orifices are connected to the switching valve which is controlled by hydraulic pressure varying according to vehicle speed. When rotation of the input shaft is low, the switching valve is connected to the oil passage having small capacity orifice, then hydraulic pressure is supplied to the hydraulic actuator through the orifice of small capacity. At this stage, as centrifugal force working on the ball in the check valve is low, the check valve is closed by even small amount of oil supply through the small capacity orifice, and raises hydraulic pressure in the actuator, so the clutch is engaged smoothly. When rotation of the input shaft is high, the switching valve is connected to the oil passage having the large capacity orifice, then hydraulic pressure is supplied to the hydraulic actuator through the large capacity orifice. At this stage, even if centrifugal force works on the ball is large, the check valve is closed by large amount of oil supply through the large capacity orifice, and raises hydraulic pressure in the hydraulic actuator, so the clutch is engaged smoothly.

    摘要: Seal rings are set in oil grooves which are situated at both sides of two oil passages communicating two hydraulic actuators which operate oppositely. First and second seal rings oil-tightly seal between the first oil passage and sleeve, while third and fourth seal rings oil-tightly seal between the second oil passage and the sleeve. Accordingly even if oil flows oppositely in each of two oil passages due to the opposing motions of the two contiguous hydraulic actuators, not oil leakage occurs. Furthermore, a draining groove is situated between the oil grooves in which the second and third seal rings are installed.

    摘要: A differential motion limiting device, for a power transmission device for four wheel drive vehicle, to regulate differential motion of a center differential device includes a wet-type multi plate clutch and an hydraulic actuator. And a switching valve is attached to an oil passage to the hydraulic actuator. In normal running condition, a switching valve is in connecting condition, and a hydraulic pressure being varied by driving conditions is applied to a hydraulic actuator. Under this condition, the clutch is slippingly engaged by certain engaging force so that torque, per certain ratio, is transmitted to the front and the rear wheels. In high speed condition, such as the maximum speed state like an overdrive, or a vehicle speed more than 100 km/h, sensors detect such state, then the switching valve is switched, and the clutch is released. As a result, lubrication oil is flowed between friction plates and separators of the clutch to release heat therefrom.

    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.
