A sheet conveying apparatus includes: a plurality of driving parts each connected to one end of corresponding one of a respective plurality of rotating shafts; a first torque adjuster connected to another end of each of the plurality of rotating shafts, the first torque adjuster applying first torque to the plurality of driving parts; a second torque adjuster that applies, to the driving parts, second torque for adjusting the first torque to be applied to the driving parts by the first torque adjuster; and a hardware processor that controls the second torque to be applied to the driving parts in the second torque adjuster in accordance with a number of revolutions of the driving part.

A method for detecting and mitigating excessive clutch disc wear for a manual transmission includes determining if a clutch pedal position is depressed greater than or equal to a first predetermined pedal position threshold and if the vehicle speed is less than or equal to a predetermined vehicle speed threshold. The method further includes determining if the clutch pedal position is depressed greater than or equal to a second predetermined pedal position threshold when the clutch pedal position is depressed less than the first predetermined pedal position threshold. The method still further includes calculating a clutch disc heat flux value and a clutch disc surface temperature. The method further includes displaying an alert/warning and a remedial action message to a vehicle operator when the clutch disc surface temperature is greater than or equal to a predetermined surface temperature threshold.

A clutch device for a powertrain of a motor vehicle, in particular a motorcycle, is provided. The clutch device includes a clutch with at least one clutch element that can be moved between at least one engaged position in which a drive assembly of the powertrain is rotationally fixed to at least one additional component of the powertrain, and at least one disengaged position in which the drive assembly is decoupled from the additional component. At least one analog sensor detects at least one measurement variable associated with the movement of the clutch element. The motor vehicle power train may be operated based on the detected at least one measurement variable.

A friction clutch having at least one clutch part (1; 31) which has at least one friction lining (3; 33) with a friction surface (10; 40) which, when the friction clutch is closed, is connected in frictionally engaging fashion to a counterpart clutch part, wherein the friction lining (3; 33) and/or a carrier element (6) of the friction lining (3; 33) is, in a circumferential direction, of undulating shape with wave troughs (20) and wave crests (18, 19), wherein, when the friction clutch is open, the friction lining (3; 33) comes into contact with the counterpart clutch part not with the entire friction surface (10; 40) but only substantially in punctiform fashion in the area of peaks (15-17) of the wave crests (18, 19). The friction lining (3; 33) has reduced friction values locally in the region of the peaks (15-17) of the wave crests (18, 19) in relation to the friction surface (10; 40) surrounding the peaks (15-17) of the wave crests (18, 19).

A steering system includes: a steering shaft to which a steering member is coupled; a worm wheel attached to the steering shaft so as to be rotatable integrally with the steering shaft; a housing that houses the worm wheel; an output shaft that is coaxial with the steering shaft and rotatable relative to the steering shaft and coupled to a steering operation mechanism; and a clutch mechanism that enables and disables transmission of power between the steering shaft and the output shaft. The clutch mechanism is housed and disposed in an internal space in the housing.

A clutch control device is provided for a four-wheel drive vehicle for transmitting drive force to the rear wheels. The clutch control device includes a dog clutch and a friction clutch, and a 4WD control unit that controls the engagement and disengagement of the dog clutch and the friction clutch. The 4WD control unit is switchable between a two-wheel drive mode and a four-wheel drive mode. The 4WD control unit is programmed to control engagement of the dog clutch so that the dog clutch is engaged after the friction clutch is engaged and the dog clutch is synchronized. During engagement of the dog clutch, the 4WD control unit is programmed to reduce a transmission torque of the friction clutch when the dog clutch engagement standby state is detected.
