摘要： Since the first-speed-ratio counter gear is carried by the first countershaft, the second countershaft carries other counter gears which transmit the relatively small drive torque, such as the forth-speed-ratio counter gear, the second-speed-ratio counter gear and the sixth-speed-ratio counter gear. Thus, there can be provided the twin-clutch transmission with two countershafts disposed coaxially which can surely obtain the advantage of making the transmission for transmitting the sufficiently large drive torque compact.
摘要翻译：由于第一速比中间齿轮由第一中间轴承载，所以第二中间轴承载传递相对小的驱动转矩的其他副齿轮，例如四速比反转齿轮，二速比反转齿轮和六速比计数器齿轮。因此，可以提供具有同轴设置的两个中间轴的双离合器变速器，其可以确实地获得用于传递足够大的驱动转矩紧凑件的变速器的优点。

摘要： A steplessly variable transmisison system for a vehicle, having a belt-pulley type transmission. An input shaft of the transmission consists of first and second shaft portions. A sleeve member is provided and is slidably splined on the first shaft portion. A driven gear is provided on the second shaft portion which is engageable with the sleeve member by a synchronizer mechanism. A reverse gear mechanism is also provided, the reverse gear of which is engageable with an outer gear formed on the circumference of the sleeve member. The sleeve member is slid by a shaft fork to thereby selectably engage the first shaft portion with the second shaft portion through either the synchronizer mechanism or the reverse gear mechanism. By selecting the engagement through the synchronizer mechanism, a forward driving transmission is implemented, whereas, by selecting the engagement through the reverse gear mechanism, a reverse driving transmission is implemented.

摘要： A four-wheel drive automobile has a driving system which includes a transversely oriented engine unit, a transmission having input and output shafts which extend transversely of the car body, an inter-axle differential gear mechanism, front and rear inter-wheel differential gear mechanisms, and a differential gear lock mechanism. The inter-axle differential gear mechanism, the front inter-wheel differential gear mechanism and the differential gear lock mechanism are arranged coaxially with one another. The differential gear lock mechanism is provided in a part of said inter-axle differential gear mechanism which is positioned at a side of the front differential gear mechanism so that the front differential gear mechanism is located between inter-axle differential gear mechanism and the differential gear lock mechanism.

摘要： An automobile auxiliary power transmission having a synchronizer mechanism comprised of a synchronizer hub, a pair of synchronizer rings cooperating respectively with a low speed and high speed gears, and an axially movable synchronizer sleeve. The synchronizer sleeve has spline teeth for engagement with the synchronizer hub and with the synchronizer rings and the gears. The spline tooth on the sleeve has an axial length which is sufficient to engage with both of the synchronizer rings when it is disengaged from both of the gears. The arrangement is effective to make the shifting stroke of the sleeve smaller than that in conventional structures.

摘要： A power transmission apparatus comprises a case defining a cavity, moveable parts arranged within the cavity, fixed parts arranged within the cavity, the fixed parts including parts moveably supporting the moveable parts, a wall at least partly constituting said case, and a thin wall portion formed in the wall, the thin wall portion being constantly pressed in an outward direction of the cavity by one of the fixed parts, so as to increase its rigidity. Membranous vibration of the case wall may be effectively controlled and the radiation noise from the transmission apparatus can be reduced without increasing the thickness of the transmission case wall or arranging ribs on it.
