A belt-type continuously variable transmission capable of continuously changing a speed reduction ratio of a driven pulley to a drive pulley, has a speed reduction ratio regulation mechanism that regulates a minimum speed reduction ratio of the driven pulley to the drive pulley. The driven pulley includes a fixed sheave, a movable sheave displaceable in an axial direction with respect to the fixed sheave, and a coil spring that urges the movable sheave toward the fixed sheave. The speed reduction ratio regulation mechanism has a swing arm that adjusts an allowable range in which moving away in an axial direction of the movable sheave with respect to the fixed sheave is possible, and a regulation drive section that drives the swing distal end portion of the swing arm to swing continuously.

Belt-type continuously variable transmission for working machine

A centrifugal clutch apparatus can include a driving-side rotational member rotatable around a shaft member connected to a driving device; clutch devices mounted on the driving-side rotational member and movable radially-outward of the driving-side rotational member. A driven-side rotational member rotatable independent from the driving-side rotational member can be arranged for covering the driving-side rotational member and can have an inner circumferential surface to engage with the clutch devices. Friction members can be adapted to be abutted against the inner circumferential surface so as to transmit the driving power of the driving device to the driven-side rotational member. The inner circumferential surface of the driven-side rotational member can be formed with a groove and a tensioning member formed as a ring-shaped member can be snap-fitted into the groove and held therein under a radially-outward biasing force.

A power transmitting apparatus can include a clutch housing, a plurality of driving and driven clutch plates, a clutch member, a pressure member, an intermediate member, a plurality of urging devices, and a back-torque limiting cam. The power transmitting apparatus can further include an urging force cut-off device for cutting-off the urging force applied to the pressure member from particular urging devices of the plurality of urging devices by separating the inner ends of the particular urging devices from the pressure member when the intermediate member is moved toward the pressure member by the action of the back-torque limiting cam.

Power transmitting apparatus

A power transmitting apparatus can be configured to switch between 2-wheel drive mode and 4-wheel drive mode and to lock and unlock a differential device. The power transmitting apparatus can comprise an input shaft connected to a driving power source i.e. an engine of vehicle and rotated around one rotational axis, a pair of output shafts of left and right sides for driving front wheels or rear wheels of vehicle when driving force is transmitted from the input shaft, a differential device arranged between the input shaft and the output shafts for absorbing the difference of rotation between the output shafts by differential action thereof, an operational shaft for performing connection and disconnection between the input shaft and output shafts by connecting and disconnecting the input shaft and the output shafts and also performing locking and unlocking of the differential means, a driving means for arbitrarily driving the operational shaft, and a case mounted on a vehicle and containing the differential means and the operational shaft characterized in that the input shaft extends from a rear side of the case facing toward the engine substantially in parallel with the operational shaft; and that the driving means is arranged on the rear side of the case.

A power transmitting apparatus for performing switching between 2-wheel and 4-wheel drive modes and locking and unlocking of a differential by an operational shaft can comprise a reversible motor, a driving shaft rotationally driven by the motor and adapted to be engaged by the operational shaft for transmitting a rotational force therebetween, a sub case for containing the motor and the driving shaft therein and mounted on the main case, an opening formed in the sub case and having a size permitting the operational shaft to be inserted and an end face of the driving shaft for engaging an end face of the operational shaft to be exposed, and a first sealing arranged on the inner circumferential surface of the opening at a position away from the driving shaft for sealing off the inside of the sub case with forming a seal between the inner circumferential surface of the opening and the outer circumferential surface of the operational shaft when the operational shaft is engaged with the driving shaft.

A power transmitting apparatus for performing switching between 2-wheel and 4-wheel drive modes and locking and unlocking of differential mechanism by an operational shaft can include a driving device comprising a reversible motor, a rotational member rotationally driven by the motor and provided with a contacting member. A spring can be arranged on the rotational member, a connecting member can be arranged to be abutted by one end of the spring so as to be rotated by the rotational member via the coil spring, and a driving shaft can be rotatably arranged relative to the rotational member and engaged by the operational shaft in its rotational direction and adapted to be rotated by the rotational member via the connecting member. A stay can be engaged by the driving shaft in its rotational direction and provided with a contacting member. A substrate can be arranged so as to be contacted by the contacting members respectively of the rotational member and the stay and formed with a conducting patterns forming predetermined electric circuits in accordance with the rotational angles respectively of the rotational member and the driving shaft. The rotational member, connecting member, stay and substrate can be formed as separate parts and adapted to be assembled to the driving shaft in order.

A power transmission apparatus with a reaction force converted by a boosting mechanism used as a fastening force for an electromagnetic clutch has a solenoid (); an electromagnetic clutch including a rotor () for transmitting the magnetic flux of the solenoid (); an armature () attracted onto the rotor () by the magnetic flux, and a return spring () urging the armature () in a direction away from the rotor () to create a clearance 't' therebetween. A boosting mechanism converts a torque of the input member (housing) () to an axial thrusting force when the armature of the electromagnetic clutch is attracted onto the rotor. A main clutch connects the input member () and the output member (shaft) () via the thrusting force generated by the boosting mechanism. This transmits the torque of the input member () to the output member ().
