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.

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.

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.

A belt-pulley type steplessly variable vehicle transmission mechanism including a belt-pulley type transmission and a reverse gear mechanism both connected with an output differential gear device. A selecting mechanism is provided for connecting the input member alternately with the belt-pulley type transmission or the reverse gear mechanism so that the reverse drive can be made at a constant speed ratio.

An automobile powertrain has at least an engine placed in an engine room and oriented so that its crankshaft is directed transversely, and a transmission placed in the engine room behind the engine. The transmission has input and output shafts arranged coaxially with each other and directed parallel to the crankshaft of the engine. An engine clutch is directly connected to the crankshaft, and a power transfer arrangement is disposed oppositely to the engine with respect to the engine clutch and operationally couples the engine clutch to the input shaft so as to transmit engine output to the transmission. The transmission, engine clutch and power transfer arrangement are independently accommodated in separate chambers of a single unit powertrain case. The transmission chamber and the power transfer chamber are connected to each other by an oil passage through which the input shaft extends from the transmission to the power transfer.

An engine unit includes an engine and a power train having a transmission and the engine unit is mounted sideways on a vehicle body with the power train positioned rearward of the engine. The engine and the power train are housed in a single engine housing and an oil pan common to the engine and the power train is mounted on the lower side of the engine housing below the engine and the power train. The length of the oil pan in the transverse direction of the vehicle body is smaller than the engine housing and auxiliary mechanisms are disposed in the space on one side of the oil pan and below the engine housing.

A power train includes a transmission having transmission shafts, with axes of rotation parallel to a crankshaft of an engine. The transmission shafts extend in a transverse direction of a vehicle. A drive axle is connected to drive wheels of the vehicle , and a drive axle differential differentially drives the drive wheels through the drive axle. A center differential is provided to differentially drive the front and rear drive wheels. The drive axle has an axis of rotation placed below and parallel to the axis of rotation of the transmission shafts. The drive axle differential and center differential are disposed side by side in the transverse direction of the vehicle body on, and in alignment with, the axis of rotation of the drive axle. The drive axle differential is located closely adjacent to the transmission in the transverse direction.

A powertrain includes an engine and a transmission and has a center inertial axis extending in a transverse direction of the vehicle body. The powertrain is mounted on the vehicle body for inertial movement about the center inertial axis by a pair of elastic mountings, disposed on opposite sides of the powertrain and not below the inertial axis. Another elastic mounting is disposed behind the powertrain. An exhaust pipe assembly, extending rearwardly and down behind the powertrain from the engine, is flexibly supported by a retainer connected, either directly or through the other elastic mounting, to the powertrain.
