A vehicle drive-force transmitting apparatus defines drive-force transmitting paths provided between input and output shafts. The drive-force transmitting paths include a first drive-force transmitting path provided with first and auxiliary engagement devices, such that the auxiliary engagement device is located between the first engagement device and the output shaft in the first drive-force transmitting path. The first drive-force transmitting path is established by engagement of the first engagement device operated by a hydraulic pressure which is controlled by an on-off solenoid valve, such that a drive force is to be transmitted along the first drive-force transmitting path through the first and auxiliary engagement devices when the first drive-force transmitting path is established.The auxiliary engagement device transmits a drive force during a driving state of the vehicle and cuts off transmission of the drive force during a driven state of the vehicle.
本发明在具备多个动力传递路径和对各个动力传递路径进行断开与连接的卡合装置的车辆用动力传递装置中,提供一种能够降低制造成本的结构。由于第一动力传递路径(PT1)被构成为具备第一离合器(C1)和双向离合器(TWC),因此即使在第一离合器(C1)的C1控制压力(Pc1)通过开关电磁阀(100)而被控制的情况下,也能够进行与第一离合器(C1)的C1控制压力(Pc1)通过线性电磁阀而被控制的情况相同的行驶。此外,由于电磁阀由开关电磁阀(100)构成,因此与由线性电磁阀构成的情况相比,能够降低制造成本。
