摘要： It is intended to amplify a torque not only in forward movement but also in backward movement. The present drive unit includes a motor, a torque converter and a power output part (4). The torque converter is a component to which a power is inputted from the motor. The power output part (4) outputs the power, inputted thereto from the torque converter, to a drive wheel. The power output part (4) includes a first gear train (41) and a second gear train (42). The first gear train (41) outputs the power, inputted to the power output part (4) from the torque converter, in a first rotational direction. The second gear train (42) outputs the power, inputted to the power output part (4) from the torque converter, in a second rotational direction reverse to the first rotational direction.

摘要： It is intended to enable efficient torque transmission. The present torque converter (3) includes a cover (31), an impeller (32), a turbine (33), a stator (34) and a first one-way clutch (35). The cover (31) is a component to which a torque, outputted from a prime mover, is inputted. The impeller (32) is unitarily rotated with the cover (31). The turbine (33) is opposed to the impeller (32). The stator (34) is disposed between the impeller (32) and the turbine (33). The first one-way clutch (35) makes the cover (31) rotatable relative to the turbine (33) in a forward rotational direction. Besides, the first one-way clutch (35) rotates the cover (31) unitarily with the turbine (33) in a reverse rotational direction.

摘要： The present invention addresses the problem of providing a power transmission device for a vehicle in which a torque converter can be reduced in size. This power transmission device 1 is provided with a motor 13 and a torque converter 15. A characteristic line TL1 for the torque converter is determined on the basis of a capacity coefficient Y1 of the torque converter 15. The characteristic line TL1 for the torque converter indicates a torque T of the torque converter relative to each rotational speed V of the torque converter 15. A characteristic line ML for the motor indicates a maximum output torque T of the motor relative to each rotational speed V of the motor 13. The torque converter 15 has the capacity coefficient Y1 such that the characteristic line TL1 for the torque converter intersects the characteristic line ML for the motor in a first range RA.

摘要： It is intended to realize compactness in device size for a torque converter including a lock-up device using a centrifugal clutch. The present torque converter (1) includes a front cover (2), an impeller (10), a turbine (11), a stator (12) and a centrifugal clutch (4). The impeller (10) is coupled to the front cover (2), forms a hydraulic oil chamber together with the front cover (2), and includes an impeller core (17). The turbine (11), from which power is outputted, is provided in opposition to the impeller (10) and includes the turbine core (22). The stator (12) is disposed between an inner peripheral part of the impeller (10) and that of the turbine (11), and regulates the flow of hydraulic oil flowing from the turbine (11) to the impeller (10). The centrifugal clutch (4) is disposed in a space between the impeller core (17) and the turbine core (22), and directly transmits the power from the impeller (10) to the turbine (11) when a rotational speed of the turbine (11) is greater than or equal to a predetermined value.

摘要： It is intended to prevent a vehicle from moving backward in starting movement on a slope. A drive unit (100) includes a motor (2), a torque converter (3), a brake sensor (81) and a controller (80). The torque converter (3) is a device to which a torque, outputted from the motor (2), is inputted. The brake sensor (81) detects a braking operation amount. The controller (80) executes a first control of controlling the torque outputted from the motor (2) based on the braking operation amount.
