PURPOSE:To surely prevent the oscillation of a differential device due to reaction force by connecting the differential device to a fitting surface nearly orthogonal to the peripheral direction of a drive shaft, extending left and right from the differential device, out of strength members, positioned in the perimeter of the device, via a connecting member. CONSTITUTION:The input shaft side end pa...

PURPOSE:To considerably lighten and make compact an unmanned operation device by composing an unmanned operation mechanism, provided according to various operating tools respectively, so as to enable the unmanned operation of plural operating tools with one actuator CONSTITUTION:In an unmanned operation device 3 for an unmanned type farm tractor, a brake operation mechanism 5, acceleration operati...

PURPOSE:To set the connecting force of a friction element to a level corresponding to the travelling condition by reducing the speed to increase the output according to the speed demanded by a driver in comparison with the speed when a power mode is set in the case where an economy mode is set. CONSTITUTION:A control unit 10 sets in an alternative way the power mode where low speed stages are ofte...

PURPOSE:To improve control responsiveness by correcting the setting of ignition timing by a given quantity to an angle-delay side from request ignition timing, and compensating opening by a quantity supplementing a torque lowering part due to the correction to the angle-delay side when a suddenly changing condition of target driving force is presumed. CONSTITUTION:When a suddenly changing conditio...

PURPOSE:To increase the transmission torque by providing a push means to be pushed to the inside of an operating chamber with the moving speech of the viscous fluid in the operating chamber, in which resistance plates are engaged with a first and a second shafts mutually for arrangement and the viscous fluid is filled. CONSTITUTION:The viscous fluid L is filled in an operating chamber 5, in which ...

PURPOSE:To smoothly and rapidly engage and disengage a friction clutch and to eliminate the necessity of a torque isolating bearing by incorporating a return spring for urging a pressing member in a direction in which the friction clutch is disengaged, between a planetary gear and the pressing member. CONSTITUTION:When an electromagnet 97 is denergized, a pressing member 69 is returned rightward b...

PURPOSE:To prevent the generation of abnormality in an engine operating condition, by changing an engine operation control mode from a non-drive range to a drive range when a rate of change in rotating speed of an output shaft has become a value not greater than a negative set value. CONSTITUTION:A transmission control unit 200 receives a signal from a speed range detecting sensor 47, and selects ...

PURPOSE:To obtain a control device which can change a control mode of operation, by providing a delay time setting means or the like by a change of oil temperature in a fluid power transmitting means and controlling an engine to accurately correspond to its applied load when a speed change range is switched. CONSTITUTION:A transmission control unit 200, after an engine is started, receives a detec...

PURPOSE:To enable to easily and surely assemble in a predetermined positional relationship by a structure wherein a motor and a transmission mechanism with a speed reduction means are mounted to a housing member as made into an integral body and at the same time an opening, through which the output of the transmission mechanism is taken out, is provided at the side of the housing member. CONSTITUT...
