摘要： A power transmission mechanism for transmitting a driving force from a drive shaft to a driven member of a gear via a one-way clutch is provided. The one-way clutch includes a swinging clutch portion swingably fitted in a clutch portion housing groove formed in a first end portion of the drive shaft. The swinging clutch portion has a cylindrical portion as the axis of rotation and a projecting portion. When the drive shaft rotates, the projecting portion of the swinging clutch portion is raised by a slit of a collar fitted onto the drive shaft, engaging one of a plurality of engaging grooves formed in the inner peripheral surface of the driven member. When the drive shaft does not rotate, the swinging clutch portion lies down, and the projecting portion does not engage any engaging groove, allowing the driven member to rotate bidirectionally relative to the drive shaft.

摘要： A control system for a variable displacement pump driven by a drive source for driving a vehicle is provided. The variable displacement pump pressurizes hydraulic oil, and is switchable between a full capacity operation in which a discharge flow rate is maximized and a partial capacity operation in which the discharge flow rate is lower than that in the full capacity operation. It is determined whether an operation for starting the drive source has been performed. A rotational speed of the drive source and a temperature of the hydraulic oil are detected. When the rotational speed of the drive source is equal to or higher than a predetermined rotational speed and the hydraulic oil temperature is equal to or lower than a predetermined temperature, immediately after the operation for starting the drive source is performed, the partial capacity operation of the variable displacement pump is performed. This control suppresses generation of untoward noises caused by the operation of the variable displacement pump when starting to drive the vehicle.

摘要： A failure detecting apparatus for a hydraulic circuit of a gearbox includes an operating-state detector. The operating-state detector is configured to detect an operating state of a subject to be controlled with a control-signal pressure output from a solenoid valve. A current setting device is configured to set an electrical current supplied to a solenoid so as to close an output oil passage when a modulator valve is normal and to open the output oil passage when an open failure occurs in the modulator valve, while the solenoid valve is conductive. A failure determining device is configured to detect a failure of the modulator valve when the operating state of the subject to be detected by the operating-state detector is abnormal after a value of the electrical current to be supplied to the solenoid is set at the current setting device.

摘要： An overload protecting device assembled in an auger transmission is disclosed as including a worm wheel having its side wall formed with a plurality of wheel-side protruding segments, a boss member engaging with the wheel and fixedly coupled to an auger shaft for non-rotating relationship, and a slide washer having a plurality of wheel-side projections facing the wheel-side protruding segments. When the auger shaft encounters a torque exceeding a given value, the worm wheel and the boss member are enabled to rotate relative to one another. As the wheel-side projections ride on the protruding segments, the slide washer is moved in a direction opposed to the worm wheel. A washer detection switch detects such a movement to produce a detection signal to forcibly stop the operation of an engine.

摘要： Line pressure is adjusted by one valve for supplying the pressure to control the engagement of a clutch in normal and abnormal operating conditions. In the normal operating condition, the valve control pressure which is controlled by a starting clutch control valve 41 is used for the control of a clutch pressure control valve 42, so the line pressure from a line 61b is adjusted to control the engagement of the starting clutch 5. If there is a breakdown, two electrically controlled valves 41 and 45 are turned off, and the line pressure is applied through another line 64. As a result, the spool of a shift restriction valve 43 is shifted to the left, so the hydraulic oil is supplied to a pitot flange 51. In this condition, the pressure (correspondent pressure) which corresponds to the rotational speed of the engine is supplied as a signal pressure from a pitot pipe 53 through lines 66 and 67 to the shift restriction valve 43. This hydraulic controller adjusts the line pressure in the line 61b by using this correspondent pressure for controlling the engagement of the starting clutch 5.
