Abstract: An output shaft is supported by means of a ball bearing at one end, a radial needle bearing and a thrust bearing. The ball bearing is arranged for supporting the output shaft against most part of radial load. On the other hand, the trust bearing is arranged for supporting the output shaft against the thrusting force which is exerted on the output shaft while the engine driving torque is transferred therethrough. Such construction reduces radial and thrusting stress to be exerted on the needle bearing. Therefore, the radial needle bearing to be used in the shown construction is required substantially small load capacity and thus can be satisfactorily small for allowing the transaxle unit to be designed compact.

Abstract: A drive transmission which is particularly suitable for ship propulsion, comprises nested, contra rotating propeller shafts which in one example are driven by a single input shaft and which transmits contra rotating drives to the shafts via respective planet carriers.

Abstract: The force-locking connection between a shaft (1) and driving elements (21) attached to it is improved or achieved via a slight plastic expansion of the shaft in that the driving elements are arranged in groups and connected by connecting sleeves (22) produced so as to be integral with the driving elements. The higher degree of elastic expansion is limited to the region of the connecting sleeves so that the driving elements themselves are largely excluded from this process. The dimensional accuracy of the finish-machined driving elements is not adversely affected. If necessary, recesses (27) may be produced to form webs (24) as a result of which the elastic deformation occurring in the inner region (23) is reduced.

Abstract: A reverse-engaging condition is prevented by a reverse inhibit valve operated by the solenoid valve even if a shift lever is operated to a reverse range at forward running. A solenoid valve controlling a 1-2 shift valve is "OFF" when controlling a manual valve to a reverse range under 7 km/h of a vehical speed. The reverse inhibit valve is at a right-half position. Therefore, the hydraulic pressure from the reverse range port of the manual valve runs through oil passages and supplied to the hydraulic servos. At forward running over 7 km/h the solenoid valve is switched "ON", the reverse inhibit valve is switched to a left-half position and oil passages are isolated. When the solenoid valve is switched at forward running, a hydraulic pressure from a R range port of the manual valve does not operate on a difference of cross sectional areas of lands of the reverse inhibit valve, so that the reverse inhibit valve is kept at the right-half position together with a pressing force of a spring therein.

Abstract: A control system for internal combustion engine installed in vehicle with automatic transmission which lowers the engine output torque for reducing the shock apt to be felt by the passengers of a vehicle equipped with an automatic transmission at the time of shifting gears. The clutch speed ratio between the transmission input and output shafts is calculated to compare with a first value. If the ratio goes beyond the first value, engine output torque is reduced by a first amount. Then the ratio is compared with a second value and if the ratio comes within the second value, the torque is further reduced by a second amount which is greater than the first amount. The ratio is continuously calculated and is again compared with a third value. When the ratio comes within the value, the torque is restored to the first reduction amount. The ratio is finally compared with the fourth value and if it comes within the value, the torque is fully restored to the initial state.
