摘要： A transfer portion connected to the output shaft of a transmission portion has a front planetary gear unit the output element of which is connected to the front wheels and a rear planetary gear unit the output element of which is connected to the rear wheels, the two units being connected to each other by a common element. The output shaft of the transmission portion is directly connected to the input element of either of the planetary gear units, while the same is connected to the input element of the other planetary gear unit via a clutch C.sub.3. Furthermore, the input element of the other planetary gear unit is connected to the case via a brake B.sub.4. Therefore, the reduction function can be realized in cooperation with the two planetary gear units. As a result, the four-wheel drive device is lightened. Furthermore, since the differential gear device is constituted by the planetary gear unit, a compact and light four-wheel drive device can be provided and the neutral state can be created by completely freeing the front and the rear wheels.

摘要： A continuously variable speed transmission having a belt drive continuously variable speed transmission in which a belt is wrapped around primary and secondary pulleys each supported on a shaft and each consisting of a pair of sheaves capable of relatively moving axially, and a forward/reverse rotation changeover mechanism. The belt drive continuously variable speed transmission is provided with a pressure adjusting cam mechanism for applying an axial force corresponding to a transmitted torque to at least one of the pulleys, ball screw mechanisms for axially moving the movable sheaves of the pulleys. A fluid torque converter is disposed on the transmission upstream side of the primary pulley. In the belt drive continuously variable speed transmission, the pressure adjusting cam mechanism produces and axial force corresponding to the transmitted torque to clamp the belt, and the power is transmitted by the effect of this clamping force without belt slip. If at the time of vehicle starting the torque of the fluid torque converter is increased, the pressure adjusting cam mechanism produces a larger axial force corresponding to the increased torque, thereby clamping the belt by a larger force to prevent the belt from slipping during transmission of power. This large belt clamping force is produced for only a short time for vehicle starting. As the torque of the fluid torque converter is reduced to a coupling range, the axial force produced by the pressure adjusting cam mechanism is correspondingly reduced automatically. The belt is clamped by a reduced axial force for a greater part of the operating time.

摘要： An automatic transmission hydraulic controller having a multiplicity of hydraulic servos for respectively controlling a multiplicity of frictional engagement elements. A hydraulic pressure to be supplied to the hydraulic servos is applied to accumulator chambers of a multiplicity of accumulators. A line pressure to be supplied to the hydraulic servos is produced by a primary regulator valve and an engine output pressure control valve is controlled by an electrical signal from a control section to produce a hydraulic pressure corresponding to the engine output. Each of at least two particular ones of the multiplicity of accumulators has a back pressure chamber formed at the rear of a piston. The pressure receiving area of this back pressure chamber and that of the corresponding accumulator chamber are substantially equal to each other. Only one of the frictional engagement elements operated by the hydraulic servos communicating with the particular accumulators is changed over from a released state to an engaged state while the other frictional engagement elements are not changed over from a released state to an engaged state, when the transmission is shifted to a predetermined speed. There is no substantial influence of a change in the line pressure upon the operating state of the other frictional engagement elements.

摘要： In a system for controlling a vehicle by exchanging signals between an electronic controller for controlling a vehicle transmission and another electronic controller for controlling a vehicle engine, the transmission controller incorporates a monitor circuit which receives, via an interface circuit of the engine controller, a signal output from the transmission controller through a communication circuit, and which is capable of detecting abnormalities of the interface circuit of the engine controller. If an abnormality of the interface circuit of the engine controller takes place such that the engine torque cannot be reduced although the transmission controller issues an instruction to reduce the engine torque, the transmission controller maintains the line pressure instead of reducing the same to cope with such a situation, thus effecting fail-safe control.

摘要： In engine torque control in a motor vehicle having an engine and a stepping type of transmission, input and output speeds of the transmission are constantly detected by sensors disposed in input and output portions of the transmission, thereby obtaining a gear ratio (measured value) of the transmission. If the ratio of the difference between this gear ratio and a predetermined gear ratio before the gearshift (theoretical value) to the latter gear ratio before the gearshift exceeds a predetermined value, the start of gearshift is decided. If the ratio of the difference between the gear ratio of the transmission (measured value) and a predetermined gear ratio after the gearshift (theoretical value) to the latter gear ratio after the gearshift becomes smaller than a predetermined value, the end of gearshift is decided. A set level by which the torque of the engine should be reduced during the period between the start and end of the gearshift is determined by reading reduction data previously set with respect to the throttle opening and the type of gearshift. The torque output from the engine is reduced on the basis of the reduction data by controlling the ignition timing retardation angle or the fuel injection rate.

摘要： An electronically controlled automatic transmission in which the transmission gear stage and engaging or disengaging operations of a lock-up clutch in a torque converter are determined on the basis of the number of transmission output revolutions and the throttle opening and in which a shifting solenoid and a lock-up solenoid incorporated in the transmission are controlled in. The transmission has a sensor for detecting an input rotational speed. The number of transmission input revolutions output from this sensor and the number of transmission output revolutions are compared with each other, thereby detecting malfunction of a transmission output speed sensor. If the transmission output speed sensor malfunctions, gearshift and lock-up control are performed on the basis of the number of transmission output revolutions calculated from the number of transmission input revolutions and the corresponding gear ratio. The transmission also has an malfunction alarm device for issuing an alarm indicating malfunction of the transmission output speed sensor in response to a signal output from an electronic control device. When both the transmission output speed sensor and the transmission input speed sensor operate normally, the number of revolutions output from the transmission output speed sensor and the number of transmission output revolutions calculated by the electronic control device from the number of transmission input revolutions and the gear ratio are compared, thereby detecting malfunction such as slip failure of a friction member in the transmission or shift failure.

摘要： A pressure control valve includes a spool valve slidable in a valve sleeve having a supply port, an output port and an exhaust port, and adapted to receive a load caused by an electromagnet and applies through a push rod, a spring load, and an output pressure feedback load. The balance among the loads is arranged to control the output pressure at a level corresponding to the electric signal input to the electromagnet. Provision is made for preselecting the gradient of the attractive force of the electromagnet with respect to the stroke of a plunger slidable within the core of the electromagnet and for adjusting the axial position of the plunger. Specifically, the electromagnet includes a coil assembly, a cylindrical core having an axially extending opening through which receives the push rod, and a cup-shaped plunger fixed to one end of the push rod and covering the core. The inner cylindrical surface of the cup-shaped plunger is tapered to converge toward the bottom of the plunger. The push rod position is adjusted by bringing the tip of the push rod into contact with a screw member threaded into a hole in a cylindrical portion extending from the center for a cover of the electromagnet portion. The push rod axial position is adjusted by inserting a ring between the mutually confronting tips of the push rod and a distal column portion of the spool valve.
