Abstract: A method and system for detecting a failure of an automatic transmission for a vehicle employing a speed shift range switch operation signal from a speed shift range switch as one of the control signals to control the automatic transmission. The method is carried out by: detecting a speed shift range from the speed shift range switch; generating a start signal indicating a starting state of a starter for expediting a start of an engine for the vehicle; and automatically controlling the automatic transmission so as to maintain the speed shift range in the case where "P" or "N" range is not detected when the start signal is "ON".

The first, second and third shafts are arranged in a triangular configuration in an end view. A fluid coupling, a main transmission and a counter drive gear are arranged on the first shaft. A counter driven gear, meshing with the counter drive gear, and a reduction gear are both arranged on the second shaft. A differential unit is interposed to drive the third shafts and has a ring gear meshing with the reduction gear. The counter drive gear is located on the first shaft between the fluid coupling and the main transmission, has a supporting boss portion extending toward the main transmission and is supported by the transmission case. The first shaft extends from the fluid coupling and through the counter drive gear for connection to at least one input element of the main transmission.

Abstract: An automatic transmission system includes a drive device, electronic control and a valve control. An accelerator pedal, a brake pedal, speedometer and a gear will send signals to the electronic control. Based on these signals, the electronic control will control the valve control. Hydraulic fluid is provided to the drive device based upon operation of the valves in the valve control. The drive device contains a plurality of clutches for each of the valves of the valve control. These clutches are sequentially engaged by sequential operation of the valves in order to connect the engine shaft with an axle of the vehicle to thereby drive the vehicle.

Abstract: A transmission with a static, hydraulic continuously-variable-speed transmission mechanism comprising a hydraulic circuit having a closed circuit, a hydraulic pump connected on the crankshaft of an engine, and a hydraulic motor having a motor output shaft coaxial with the axis of rotation of the hydraulic pump, and contained in a casing with its axis extended in parallel to that of the crankshaft. The static, hydraulic continuously-variable-speed transmission mechanism has a small construction and has an increased degree of freedom of selection of speed change ratio. An output shaft, i.e., the final output shaft of a transmission is supported for rotation on a casing with its axis extended in parallel to that of a static, hydraulic continuously-variable-speed transmission mechanism. A motor output shaft and the output shaft can be interlocked by a reduction mechanism.

Abstract: A method and an apparatus for controlling a car equipped with an automatic transmission having a lockup clutch. According to the control method when the lockup clutch is in the lockup state, a variation of a generated torque is detected. When the range of the torque variation detected exceeds a predetermined value, an engine torque is reduced by controlling the engine, and the automatic transmission is controlled to compensate for a reduction of the driving torque due to a reduction of the engine torque. Thus, the speed change ratio is changed to the low gear side.

Abstract: A small, inexpensive, comparatively simple differential gear having reliable revolution difference restricting effects includes a rotary casing and a retainer having a common rotation axis. Torque is transmitted to a groove of a pair of rotary members via rolling elements so the rotary members rotate with the casing. When a revolution difference occurs between the rotary members, rolling elements retained in guide slots of the retainer roll along the grooves of the rotary members so there is reciprocal movement within the range of the guide slots. When a force causing a revolution difference between the rotary members is applied from the side of only one of the rotary members, the resulting reaction force restricts the revolution difference between the pair of rotary members. This is because the rolling elements which come to the following side when the revolution difference exists trail the groove which comes to the leading side when a revolution difference occurs in response to their own movements.

The gear wheel set includes a connecting shaft extending transversely from an intermediate portion of the crank axle, a driving bevel gear mounted rotatably on the connecting shaft, and first and second driven bevel gears mounted rotatably on the crank axle and disposed respectively on two sides of the connecting shaft. The first and second driven bevel gears mesh respectively with the driving bevel gear, and the first driven bevel gear can be locked selectively to the tubular shell.

Abstract: In case where an engine rotational detection signal from an ignition pulse generator is not appropriately detected even if an amount of induction air and a fuel injection amount are larger than predetermined values, an engine rotational signal failure is decided, and an automatic transmission is controlled in a state before the decision. Therefore, the automatic transmission control based on the engine rotational speed such as, for example, a speed shift control (ordinarily a shift control), a lockup control (ordinarily a lockup control, a smooth control), a line pressure control (ordinarily a line pressure control, a starting time control) can be appropriately controlled. Thus, the automatic transmission control can be executed based on the engine rotational speed.

Abstract: A load distributing planetary gear or epicyclic transmission having a sun gear, an annulus gear and a planet wheel carrier supporting a plurality of planet wheels, all of the gears being helical and the planet wheels being simultaneously meshed with the sun gear and the annulus gear. Each planet wheel is mounted on a distal end of a flexible shaft, which is supported by the planet wheel carrier on an opposite end, by a journal which permits swivelling of the planet wheel. Each planet wheel is held in place by a component which is capable of sliding only in a plane extending substantially perpendicular to a plane passing through the axis of rotation of the planet wheel and the axis of rotation of the sun gear. The sliding component is offset axially along these axes relative to the planet wheel, preferably being located on the side of the planet wheel facing towards the planet wheel carrier.

The second clutch surface is disposed at an angle of between about 3.degree. and 7.degree. relative to the longitudinal axis. A biasing device, such as a plurality of compression springs, biasingly engages the second clutch surface with the first clutch surface, and effects a preload force of between about -200 to +500 pounds against the side gear in a direction generally parallel to the longitudinal axis.

Abstract: A three degree-of-freedom robotic manipulator is constructed from three rotary drives. The rotary drive consists of a relatively small diameter cylindrical driving member coupled to a larger diameter cylindrical driven member. The driven member of a second rotary drive is mounted perpendicularly to the driven member of a first drive. The driven member of a third drive is mounted to the periphery of the driven member of the second drive with its axis of rotation parallel to the driven member of the second drive. The driving member of the third drive is located with its axis of rotation coincident with the axis of rotation of the driven member of the second drive. Motors powering the second and third driving members are mounted to the driven member of the first drive roughly centered over its axis of rotation. An extension arm for mounting the end effector is fixed to the driven member of the third drive. This arrangement reduces the number of required components and minimizes motor movement to reduce inertia.

Abstract: An automobile automatic transmission shift control system causes a specific gear shift by locking a first frictional element and unlocking a second frictional element simultaneously. The system delays a commencement of the unlocking of the second frictional element relative to a commencement of the locking of the first frictional element during the specific gear shift while a down control of engine torque is not conducted or when an engine output torque is large.
