摘要： A mechanical shaft joint boot integrally made up of a large-diameter ring portion and a small-diameter ring portion with a bellows portion interposed therebetween, and a straight portion connecting the bellows portion with the large-diameter ring portion. The distance 11 between the large-diameter ring portion and the small-diameter ring portion is smaller than the distance l2 between a large-diameter ring mounting portion and a small-diameter ring mounting portion of the joint, and the outside diameter of a first crest of the bellows portion is not larger than the inside diameter of the straight portion. Accordingly, when a shaft of the joint inclines to cause inclination on one side of the boot, a surface pressure being imposed on the first crest is not increased correspondingly, thereby suppressing its wear and enhancing service time of the boot.

摘要： A shift device, which sends a command signal to an electric actuator for shifting a plurality of gear ranges of a transmission of a vehicle by the electric actuator. The gear ranges include a plurality of drive ranges and a parking range. A shift lever is arranged to move between a neutral position and a plurality of manipulation positions located about the neutral position. A restoration mechanism restores the shift lever to the neutral position. A first sensor electrically detects a manipulation performed to select one of the drive ranges. A second sensor electrically detects a manipulation performed to select the parking range. The first sensor detects toward which of the manipulation positions the shift lever is manipulated.

摘要： An automatic engine stop/restart-type vehicle and control method determine whether a vehicle is in a non-running range. The vehicle comprises: an engine; a transmission, an oil pump and a controller. The transmission has a coupling element that transmits an output torque of the engine. The oil pump supplies a hydraulic pressure to the transmission. The controller controls an output from the engine; controls the hydraulic pressure supplied to the transmission; and determines whether the engine is in an automatic stop state when a manually set mode of the transmission is shifted from a non-running range to a running range. A hydraulic pressure compensation procedure is performed to conform friction coupling characteristics of the coupling element and input characteristics of the transmission with each other if the controller determines that the engine is in the automatic stop state.

摘要： A method for controlling gear shifting of a transmission in a vehicle. The transmission is supplied with electric power from a battery or an alternator and drives an actuator to shift gear ranges of the transmission. The transmission has an output shaft that becomes difficult to rotate if a predetermined range is selected when the engine stops running. The method includes determining whether a gear range differing from the predetermined range is selected when the vehicle stops traveling, and forcibly shifts the gear range to the predetermined range when a gear range differing from the predetermined range is selected by driving the actuator with electric power supplied from the alternator.

摘要： A compact automatic transmission for a vehicle capable of preventing increase in relative rotational speed between shift elements. A planetary gear unit is provided with a sun gear to which rotation of an input shaft is input, a carrier that can be stopped from rotating, and a ring gear for outputting, to a planetary gear set, rotation that is reduced in speed relative to that of the input shaft. A clutch is connected/disconnected, the input shaft and the sun gear are appropriately connected/disconnected, and the carrier is appropriately stopped/unstopped by a brake and a one-way clutch. This prevents relative rotational speed between shift elements of the gear unit that does not participate in a shifting operation from excessively increasing. When the clutch is disposed between the input shaft and the sun gear, the torque capacity of the clutch can be reduced as compared with the case where it is disposed between the gear unit and the gear set. Therefore, the clutch can be formed into a more compact structure and the overall automatic transmission can be made more compact.
