摘要： PROBLEM TO BE SOLVED: To improve gap accuracy by providing a first bearing setting a gap between a first rotating member and an electromagnet and a second bearing supporting the first rotating member between a fixing member and the first rotating member and arranging both of the bearings at the same location of the axial direction by being radially overlapped. SOLUTION: Gaps E1, F1 are set by a bearing 41 to be a single component mounted between an inner cylinder part 28 and an electromagnet 35. Because the bearing 41 to be a radial bearing is provided with dimensional accuracy by which the radially relative location of a member to be mounted and a supporting member can be exactly set, setting accuracy of the gaps E1, F1 can be improved as much as possible. Components such as the bearing 41, a whirl-stop mechanism and a sealed bearing 16 are arranged at almost the same location of a axis A1 direction by being radially overlapped. Therefore, arrangement space of the axis A1 direction of the components is suppressed as much as possible and a driving force transmission device can be miniaturized in the axis A1 direction.

摘要： PROBLEM TO BE SOLVED: To facilitate the circumferential direction positioning work of an electromagnet and a casing by forming an opening part in the casing and arranging a positioning mechanism by being faced toward the opening part. SOLUTION: When a cover 6 and a differential carrier 1 are coupled in an assembling work, these cover 6 and carrier 1 and an electromagnet 35 are relatively moved in the axis A1 direction and the electromagnet 35 is inserted into the cover 6 by being passed through an opening 6A. Because the electromagnet 35, a projecting part 69 and a whirl-stop pin 72 are arranged by being faced toward opening parts 1A, 6A, a worker can confirm the circumferential direction phase of the electromagnet 35 and the cover 6, that is, the whirl-stop pin 72 and a notched part 70 from the outside of the cover 6 and the carrier 1 immediately before a state that the cover 6 and both of the end faces of the carrier 1 are abutted. When the phase is different, the carrier 1 and the cover 6 are stopped, the electromagnet 35 is revolved, and the phases of the whirl-stop pin 72 and the notched part 70 are made to coincide with each other. Therefore, the circumferential direction positioning work of the electromagnet 35 and the cover 6 can be easily and quickly performed.

摘要： PROBLEM TO BE SOLVED: To suppress entering of foreign matter into a gap of an electromagnet of a clutch mechanism and a magnetic body by providing an isolating mechanism forming an electromagnet storing chamber by fluid-tightly isolating space in which the gap is arranged and the surrounding space. SOLUTION: A gap El between the inner periphery of an iron core 36 and the inner cylinder part 28 of a magnetic body and a gap Fl between the outer periphery of the iron core 36 and the outer cylinder part 30 of the magnetic body are set by a single bearing 41. An electromagnet 35 and the gaps El and Fl are arranged in an electromagnet storing chamber Cl by fluid-tightly isolating the electromagnet storing chamber Cl and the surrounding space by a differential carrier 1, a cover 6, a coupling case 7, an oil seal 34, an O ring 33 and a sealed bearing 33. Therefore, entering of foreign matter such as differential oil filled in a differential oil chamber Bl or abrasion powder generated by the engagement of gears each other into the electromagnet storing chamber Cl is suppressed.

摘要： PROBLEM TO BE SOLVED: To improve shift change speed performance in manual shift change in a twin clutch type transmission or the like in which a plurality of rotation power transmission systems are provided in parallel between an input shaft and an output shaft. SOLUTION: By moving a shift lever 8a to pre-shift positions PrU Pp and PrDNp, a transmission mechanism belong to the rotation power transmitting system on the clutch released side can be changed to a corresponding gear shift state without actually executing shift change. In giving an instruction for a shift change actually, sleeve driving time inside the transmission mechanism is not necessary. At timing when the shift lever 8a is moved to an up-shift position UPp or a down-shift position DNp, therefore, clutch-to-clutch operation can be executed speedily, and gear change can be completed in an early stage. Shift change speed performance in manual shift change can thus be improved. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a control device for a vehicular transmission in a power transmission passage ranging from an engine to a driving wheel, automatically coping with the irregularity of a control hydraulic pressure sensor for detecting driving control hydraulic pressure of an automatic shift control device.
SOLUTION: When finding the irregularity of the control hydraulic pressure sensor for detecting driving control hydraulic pressure P
B of the automatic shift control device using the discharge pressure of a hydraulic pump as original pressure, the original pressure P
A is automatically lowered. This suppresses the lower controllability of the automatic shift control device with high pressure due to the impossible control of the driving control hydraulic pressure P
B and prevents the application of shifting overload. For example, this suitably prevents damage to the transmission due to too strong shifting operation force or selecting operation force.

摘要： PROBLEM TO BE SOLVED: To provide a gear change control device for vehicle stepped change gear which switches the lowest speed gear step in an automatic transmission range used for general traveling to an emergency low-speed gear step having a change gear ratio larger than that of the lowest gear step without requiring any skill in the state where a drive force further larger than that in the lowest gear step is required. SOLUTION: When the state where a vehicle drive force further larger than that in the establishment of a first speed gear step (lowest speed gear step) G1 is required is determined by a drive force shortage state judgment means 82, a stepped change gear 16 is automatically shifted down from the first speed gear step G1 to the further low-speed emergency low-speed gear step GU by a gear change control means 80. Therefore, in the state where the drive force further larger than the lowest speed gear step of the automatic transmission range used for general traveling, namely the first speed gear step G1 is required, the emergency low-speed gear step having a gear ratio larger than that of the first speed gear step G1 is obtained without requiring any skill.

摘要： PROBLEM TO BE SOLVED: To provide a control device for a vehicle transmission to control an automatic clutch so that the temperature of lubrication oil in the transmission is rapidly increased. SOLUTION: In the case that viscosity of lubrication oil in the transmission 16 is high when a shift lever 170 is operated to a non-running position, since the automatic clutch 14 is controlled to the engagement side, rotation of an engine 12 is transmitted to an input shaft 42 of the transmission 16 and lubrication oil in the transmission 16 is agitated. Thereby, when a vehicle is run especially in cold environment, lubrication oil in the transmission 16 is comparatively rapidly increased in temperature. Thus, since a period in which viscosity of lubrication oil in the transmission 16 is high is shortened, a period in which the occurring period of comparatively high dragging resistance (torque) and a period in which a speed change feeling is lowered are shortened, and a shift load is relieved and durability of a synchronizing device is improved.
