The invention discloses a lower pair arc stop-block overrunning clutch comprising an outer rotating element, an inner rotating element, a friction block assembly, a wedge assembly, a first propeller assembly, a first elastic element and a synchronized push-block assembly, wherein a plurality of friction blocks of the friction block assembly are connected end to end and arranged between a first rotating ring and a second rotating ring; an drive element drives the first propeller assembly to press the synchronized push-block assembly to achieve synchronization of the friction block assembly; the first propeller assembly is stationary relative to the friction block assembly, the friction block assembly is pushed to rotate reversely with a driven element; the wedge assembly is wedged to generate a radial pressure on the friction block assembly so that the friction block assembly can achieve lower pair arc stop, thereby achieving the transfer of torque.

Methods and systems are provided for an isolator. In one example, system may include an isolator comprising a flexible laminated membrane comprising a non-linear torsional stiffness for compensation of axial, lateral, and angular displacements between a drive shaft and a clutch.

A torque limiter device includes an input shaft having a first contact surface and an output shaft having a second contact surface. The input and output shafts are operable in an engaged position wherein the contact surfaces are brought into mechanical engagement, and a disengaged position wherein the contact surfaces are separated. A biasing mechanism provides a bias force that mechanically biases the input and output shafts in one of the positions and sets a threshold torque. An electromagnet is arranged to selectively provide an electromagnetic force that opposes the bias force when an activation current is supplied. A rotation sensor arrangement measures a respective rotation of the input shaft and of the output shaft. A controller determines a difference in rotations of the shafts and selectively supply the activation current to the electromagnet so as to disengage the input and output shafts when the rotation difference exceeds a threshold.

A drive system of a header for an agricultural vehicle. The header includes a plurality of driven devices. The drive system includes a shaft configured for conveying motive power from the agricultural vehicle to the header, a gearbox configured for being located on the header and for transferring motive power to the plurality of driven devices, and a torque damper. The torque damper is operably connected in between the shaft and the gearbox. The torque damper is configured for reducing a magnitude of a torque spike.
