摘要： PROBLEM TO BE SOLVED: To support a motor generator with high accuracy without being influenced by the centering accuracy of a crankshaft of an engine and transformation of a torque converter, to improve efficiency of the motor generator, and to miniaturize thereof. SOLUTION: A motor housing 15 is disposed between a converter housing 12 and an internal combustion engine 13, and a bearing 47 is fitted to a side wall 15a provided at a front part of the motor housing. Rotor supporting members 45, 49 are independently supported by the bearing. Eccentric rotation accompanying the explosion vibration of the crankshaft 52 is absorbed by two flex plates 55, 51, and the transformation of the torque converter 5 does not have influence on the rotor supporting member 45 with separate structure due to clearance c provided therebetween.

摘要： PURPOSE:To pysically sense a torque change sufficiently by providing a hydraulic circuit to attain respective speed change stages by means of speed change output signals of a control device and a regulating means to make a speed change response in the case of manual speed change larger than in the case of automatic speed change. CONSTITUTION:Though a hydraulic circuit to operate a transmission is used in the same as usual, in order to prevent a speed change shock in the case of speed change, a delay angle quantity is set, and the ignition timing is delayed, and engine torque is reduced. In the case of manual speed change mode, a speed change control device 31 judges that torque reduction control is required in the case of speed change transitional time. The torque reduction control is carried out by reducing the delay angle quantity sent to an engine control device through a torque reduction input/output processing circuit of a driving circuit 39. Thereby, since the delay angle quantity of an engine is reduced and the engine torque is increased, a speed change response caused by engagement with frictional engaging elements can be made large, so that a torque change can physically sensed.

摘要： PURPOSE:To eliminate a difference or the like between a driver's expected shift stage and an actually attained shift stage by measuring the time for a shift lever to be at the neutral position in a manual gear shift mode, and applying such a means as attaining a forward travel range when the measured time exceeds the prescribed value. CONSTITUTION:In this automatic transmission, a shift lever is moved over the range of a shift pattern comprising a range position for an automatic gear change mode, a shift position for a manual gear shift mode, and neutral positions for respective types of mode. In this case, a sensor or the like 37 detects that the shift lever is moved to each position. Also, a control device 31 outputs a gear change signal, according to a range and a gear selected with the shift lever. Furthermore, an actuator 40 is driven to attain each gear, according to the gear change signal. On the other hand, a timer measures a time for the shift lever to stay at a neutral position in the manual gear shift mode. Also, the gear selected immediately before is maintained until the measured time exceeds the prescribed value, and a forward travel range is attained when the prescribed value is exceeded.

摘要： PURPOSE:To achieve a favorable reverse gear ratio and downsizing through rationalization of torque sharing in a five-speed automatic transmission in which a simple-connection three-planetary main transmission is combined with an overdrive transmission. CONSTITUTION:A five-speed automatic transmission is provided with three pairs of planetary gears P1 to P3 and constituted by a main transmission 1 for achieving four forward speeds and one backward speed and a front-mount overdrive transmission 2. The front-mount overdrive transmission 2 can release a direct connection stage by disengaging a clutch C-0 at backward driving, and a clutch C-2 for achieving a direct connection stage of the main transmission 1 and a brake B-5 for achieving a low speed stage are engage with each other at backward driving. The forward four stages in a proper speed changing step is achieved by direct connection of the front-mount overdrive transmission 2 and speed change of the main transmission 1, and backward driving with favorable gear ratio with an overdrive stage is achieved by speed change with the main transmission 1 and the front-mount overdrive transmission 2.

摘要： PURPOSE:To prevent generation of speed change shock to the utmost while the reduction of cost is kept by changing speed by means of a speed change train on high sped side from the speed change stage where clutch to clutch speed change is avoided when an accel opening is less than a designated value, and clutch to clutch changing speed when the accel opening is the designated value or more. CONSTITUTION:The respective signals from an accel opening sensor 12, a car velocity sensor 13, an engine water temperature sensor 14, a brake switch 15 and so on are input to an automatic transmission control computer 8, and solenoid valves S-S are on-off controlled in order to obtain a speed change stage corresponding to the car velocity and the accel opening. When the accel opening is less than a designated value, change speed is executed by using a higher speed change train than a speed change stage where clutch to clutch speed change is avoided, and when the accel opening is the designated value or more, clutch to clutch speed change is executed.

摘要： PURPOSE:To increase the torque capacity of a planetary gearing capable of transmitting as a while by fixing the tip of each leg to a plate member, forming a space for pinion among the legs, shortening its length, and increasing the number of pinions. CONSTITUTION:If it is assumed that the torque which one pinion 22 can transmit is equal regardless of the number of pinion 22 mounted, five pinions 22 for example transmit as a whole a torque 1.2 times as large as four pinions. When the number of pinions 22 mounted is increased without changing the outside dia. of a carrier 23, the total of the coupling lengths d2 decreases as long as the mounting, length d1 per pinion is constant, which causes drop of the coupling strength of a flange 23a with a plate member 23b. Therefore, the mounting length d1 is lessened as much as possible for example by machining which can give a higher processing accuracy than press, etc., and the coupling length d2 is increased, and thereby the coupling strength between the flange 23a and plate member 23b is secured.
