Abstract: A heat exchanger for a vehicle is mounted in a vehicle having a power train through which an engine coolant, an engine oil and a transmission oil flow and in which a flow rate of the engine oil and a flow rate of the transmission oil are different from each other. A first flow passage for causing the engine coolant to flow, a second flow passage for causing the engine oil to flow, and a third flow passage for causing the transmission oil to flow are formed through lamination of a plurality of plates. The heat exchanger includes a region where the first flow passage is adjacent only to that one of the second flow passage and the third flow passage through which a fluid flows at lower flow rate.

Abstract: There is provided a cooling structure whose performance for cooling ring members and brushes is enhanced. In a cooling structure applied to a slip ring device including ring members provided to an input shaft and brushes contacting with these ring members, the input shaft includes a shaft member where an external spline portion is formed, and a cylindrical member that is installed over the external circumference of the shaft member so that an internal spline portion formed on the cylindrical member is meshed with the external spline portion, and that the ring members are fixed to the cylindrical member. The internal spline portion is formed upon a portion of the inner circumferential surface of the cylindrical member that lies on the radially inward side of the ring members.

Abstract: A heat exchanging device includes: a heat exchanger configured to perform heat exchange between first operating oil used in an engine and second operating oil used in a fluid transmitting device and an automatic transmission; and a heat exchanging amount decreasing unit configured to, when a temperature of the second operating oil is lower than a predetermined temperature at which it is allowed to engage a lock-up mechanism, decrease a flow amount of at least one of the first and second operating oil flowing in the heat exchanger as compared to a case in which the temperature of the second operating oil is not lower than the predetermined temperature.

Abstract: A heat exchanger includes a plurality of plates that is stacked together to constitute first flow passages, second flow passage, third flow passage, fourth flow passage and fifth flow passage. An engine coolant flows through the first flow passages. An engine oil flows through the second flow passages and fourth flow passages. A transmission oil flows through the third flow passages and fifth flow passages. Triple-flow-passage arrangement layers in each of which each first, second, and third flow passages are disposed, and dual-flow-passage arrangement layers in each of which each fourth and fifth flow passages are disposed are alternately arranged such that flow passages of each same type are not overlaid with one another in a stacking direction of the plates.

Abstract: A heat exchanger includes first, second, third, and fourth passages. Engine coolant flows through the first passages. Engine oil flows through the second passages. Transmission oil flows through the fourth passages after flows through the third passages. Each first passage and each third passage is disposed in the same layer. Each second passage and each fourth passage is disposed in the same layer. Each first and each third passage are disposed in a different layer from the layer of each second and each fourths flow passage. Each fourth passage is disposed upstream of a first flow direction of the engine coolant in each first passage, and each second passage is disposed downstream of the first flow direction. Each third passage is disposed upstream of a second flow direction of the engine oil in each second passage, and each first passage is disposed downstream of the second flow direction.

Abstract: A transaxle includes a planetary gear reducer and a differential device. The planetary gear reducer includes a stepped pinion, a first needle bearing, a second needle bearing, and a carrier. The stepped pinion includes a pinion shaft with which a large diameter pinion and a small diameter pinion are integrated. The first needle bearing is fitted to a part of the pinion shaft outside the large diameter pinion. The second needle bearing is fitted to a part of the pinion shaft outside the small diameter pinion. The carrier is configured to support the stepped pinion via the first needle bearing and the second needle bearing such that the stepped pinion is rotatable with respect to the carrier, and to couple the stepped pinion and the differential device.

Abstract: The selectable one-way clutch includes a pocket plate, a notch plate, a cover plate, and plate-like struts. A one end portion of each strut is provided with an engagement surface and a projecting portion. Each strut comes into an erect state in which the engagement surface of the strut erects from the other surface of the cover plate toward the notch plate side. The selectable one-way clutch moves the notch plate in the axial direction to change a distance in the axial direction between the pocket plate and the notch plate, thereby carrying out switching between an out-of-engagement state in which the erecting struts cannot contact with the notches and a one-way clutch state in which the erecting struts can contact with the notches.
