An apparatus of an automatic transmission includes a control unit controlling engagement and release of engaging mechanisms. One of the engaging mechanisms is a mechanical engaging mechanism which can be switched to a first state and a second state in which rotation of a rotational element in both directions is restricted. In a reverse range, the mechanical engaging mechanism is set in the second state. If a shift range is switched to the reverse range when the mechanical engaging mechanism is in the first state, the control unit starts engagement corresponding to the reverse range after executing preparation processing. If the shift range is switched from the reverse range to a forward range in the preparation processing, the control unit establishes a forward gear range by controlling the engaging mechanisms according to a degree of progress of the preparation processing.

A steering assembly includes a rack assembly coupled to a road wheel. The rack assembly includes a housing, a ball screw, a bearing, and a retainer. The housing defines an injection port. The ball screw is at least partially received within the housing. The bearing is received within the housing and rotatably supports the ball screw. The retainer is received within the housing and includes a first retainer portion and a second retainer portion. The first retainer portion cooperates with the housing. The second retainer portion extends from the first retainer portion and is spaced apart from the housing. The second retainer portion defines a channel. The channel, the second retainer portion, and a surface of the housing defines an injection pocket.

There is provided a damper device, including: a base; a rotor rotatably supported by the base; a cap defining a housing chamber of the rotor together with the base; and viscous liquid filled in the housing chamber. The base and the cap define a reservoir chamber for the viscous liquid on an outer side of the housing chamber in a radial direction. A gap between the housing chamber and the reservoir chamber is sealed.

An arrangement includes a planet carrier. The planet carrier includes a web, a journal and a bushing. A first end of the journal is fixed in the web, at least a part of the journal projects into the bushing, and a second end of the journal is fixed in the bushing. The planet carrier further includes a stiffening element, an annular support ring, and a cap placed onto a first axial end of the bushing. An axis of symmetry of the annular support ring coincides with a center axis or axis of rotation of the planet carrier. The stiffening element is fixed in the bushing and in the support ring. The bushing and the stiffening element are connected to each other as two pieces. The stiffening element is joined to the cap.

A power train device of a vehicle includes an engine and an automatic transmission. The automatic transmission is configured such that in a neutral state, multiple ones of multiple rotary elements forming a power transmission path other than a rotary element coupled to an input member and a rotary element coupled to an output member are in a non-restraining state. The multiple ones of the multiple rotary elements include a rotary element of a predetermined brake among multiple friction fastening elements, and the predetermined brake is fastened before a fuel supply upon an engine start.

An actuator is provided, in which second support shafts are protruded to an output shaft side in an axial direction of a second planetary carrier. A power transmission member having convex portions which are protruded radially outward and receive rotation forces from the second support shafts are arranged on a second planetary carrier side of the output shaft in the axial direction. An elastic member is arranged between the second support shafts and the convex portions in a rotation direction of the output shaft. Therefore, the rotation force of the second planetary carrier due to rotation drive of an electric motor is transmitted from the second support shafts to the convex portions of the power transmission member via the elastic member.

A controller and a method for a hybrid drive, which includes an internal combustion engine and an electrical machine are provided. The internal combustion engine includes adjustment devices that deactivate the intake and exhaust valve opening actuation. The controller is designed in such a way that, in the case of at least one specified condition (such as regeneration during unfired overrun or in the case of electric travel, in particular in the case of operation with high activation frequency of the internal combustion engine, e.g., in charge sustaining or HEV operation), the intake and exhaust valves are kept at least approximately (preferably completely) closed at least approximately simultaneously while the internal combustion engine is unfired. The internal combustion engine must be connected to the electrical machine. If there is a disconnect clutch, the disconnect clutch is brought into the closed state or remains closed.

A gearbox includes a sun gear, a plurality of planetary gears meshed with the sun gear, a rotating frame supporting the planetary gears, and a housing with an internal ring gear meshed with the planetary gears. The planetary gears include a first gear and a second gear coaxially connected to each other along an axial direction and rotating synchronously, the first gear meshed with the sun gear, and the second gear meshed with the internal ring gear of the housing. The rotating frame received in the housing has an upper frame and a lower frame with a central hole, each of the plurality of planetary gears is arranged between the upper frame and the lower frame by a mounting pin, the lower frame is supported by a flange connected to the housing, the sun gear is driven to rotate so as to operate the rotating frame. The gearbox of the present disclosure has low vibration and low noise.

A transaxle includes a first motor generator, a second motor generator, a first planetary gear train, a second planetary gear train, a ring gear shaft, and a case. The first planetary gear train includes a first sun gear, a first carrier, and a first ring gear. The second planetary gear train includes a second sun gear, a second carrier, and a second ring gear. The first sun gear is coupled to the first motor generator, and the first ring gear is coupled to the ring gear shaft. The second sun gear is coupled to the second motor generator, and the second ring gear is coupled to the ring gear shaft. The first carrier and the second carrier are not rotatable relative to the case.

The present invention relates to a clamping apparatus for an antenna, the clamping apparatus including a rotation unit configured to rotate an antenna in a horizontal direction, a tilting unit configured to rotate the antenna in a vertical direction, and a rotation/vibration prevention unit configured to adjust a direction of the antenna by rotating at least one of the rotation unit and the tilting unit and prevent the antenna from arbitrarily rotating after the direction of the antenna is adjusted, in which the rotation/vibration prevention unit includes a rotation motor, a worm gear configured to be rotated by the rotation motor, a shaft configured to define at least one rotation center, and a worm wheel gear installed on an outer peripheral surface of the shaft and configured to rotate at least one of the rotation unit and the tilting unit while being rotated by the worm gear, thereby easily adjusting the direction of the antenna by controlling the rotation motor and preventing the antenna with the adjusted direction from arbitrarily rotating.
