摘要： A clutch of a clutch device is provided between a first transmission portion and a second transmission portion that are rotatable relative to a housing. A state changing unit is configured to receive a force in an axial direction from a translation portion and change a state of the clutch to an engaged state or a non-engaged state according to a relative position in the axial direction of the translation portion with respect to the housing. An urging member is configured to urge the translation portion in a direction to switch the clutch from the engaged state to the non-engaged state. A retainer member is fixed directly to the housing and is configured to restrict an axial position of the urging member.

A second drive cam groove extends from the drive cam specific position to the other side in the circumferential direction, and an inclination angle of a groove bottom with respect to one end surface of the drive cam main body is larger than that of the first drive cam groove. A first driven cam groove extends from a driven cam specific position to one side in a circumferential direction. A second driven cam groove extends from the driven cam specific position to the other side in the circumferential direction, and an inclination angle of a groove bottom with respect to one end surface of the driven cam main body is larger than that of the first driven cam groove.

摘要： An output shaft is configured by connecting a first shaft and a second shaft, coaxially arranged with each other, by a reverse input cutoff clutch 20; an end portion on one side in an axial direction of the second shaft located on an opposite side from the first shaft with a gear portion sandwiched in between in the axial direction being rotatably supported with respect to a fixed portion by a bearing device; the reverse input cutoff clutch having a function that, when rotational torque is input to the first shaft, transmits the rotational torque input to the first shaft to the second shaft, and when rotational torque is reversely input to the second shaft, completely cuts off the rotational torque reversely input to the second shaft and does not transmit the rotational torque to the first shaft, or transmits part of the rotational torque to the first shaft and cuts off the remaining portion.

摘要： A drive unit (10) for a manually driven vehicle, in particular a bicycle or an EPAC, includes a housing (12), a bottom bracket shaft (14), an electric auxiliary drive (16), and an output shaft (22) designed as a hollow shaft. The bottom bracket shaft (14) and the output shaft (22) are coaxial. The output shaft (22) surrounds the bottom bracket shaft (14) at least partially along an axial direction. A first freewheel clutch (24) and a second freewheel clutch (26) are arranged radially between the bottom bracket shaft (14) and the output shaft (22). The freewheel clutches are axially adjacent and act on the output shaft (22).

摘要： An electrified drivetrain system that maximizes power density, is readily packaged, and improves drivability is described. It includes a propulsion system having an axial-flux rotating electric machine, a torque converter having a selectable one-way clutch, and an output member that is couplable to a drivetrain. The axial-flux rotating electric machine include a first rotor coaxially arranged with a first electric stator. The torque converter includes a fluidic stator, a pump, a turbine and a torque converter clutch. The axial-flux rotating electric machine is arranged coaxially with the torque converter. The first rotor of the axial-flux rotating electric machine is coupled to the pump of the torque converter, and the turbine of the torque converter is rotatably coupled to the output member.

摘要： An electromechanical actuator (EMA) includes a plurality of modes and includes an electrical motor having a motor shaft extending along an axis (A) and that drives the shaft to rotate about the axis and a gear assembly mounted around, and in geared connection with the shaft, to rotate with the shaft. The EMA output is connected to the gear assembly such that rotation of the motor shaft causes rotation of the output via the gear assembly, the output rotating at a speed which is a predetermined fraction of the speed of rotation of the motor shaft based on the gear ratio of the gear assembly. The EMA also includes a synchroniser comprising a first conical portion connected to an end of the motor shaft, and a second conical portion connected to a ratchet. The synchroniser has an engaged position and a disengaged position.

摘要： The present disclosure relates to the field of servos, and in particular to a high-precision miniature servo with a new variable reluctance and improved motor positioning. Compared with conventional variable reluctances, the variable reluctance of the present disclosure has a longer service life, is lower in cost and is easier to machine. The motor component is directly assembled on the housing, so that the cost and space are saved, and the difficulty in mounting and positioning a miniature motor is mainly solved. A motor brush piece and the Ball element are directly machined on a PCBA circuit board, so that the problem on the difficulty and cost control of the conventional machining technology is solved.
