Abstract
A torque-limiting device for secure transmission of a rotation between an inlet baseplate and an outlet baseplate, including at least one drive bolt that forms a breaking element by shearing in case of a torque exceeding a predetermined threshold, and an intermediate baseplate that is driven by the inlet baseplate and driving the outlet baseplate. The bolt ensures driving of the intermediate baseplate and the inlet baseplate or the outlet baseplate. The intermediate baseplate includes a locking element by shape cooperation with a locking part of the bolt. The intermediate baseplate is formed by two plates pressed against one another, one of which is used for housing of the locking part of the bolt and the other of which is used for axial support of the locking part and housing of the screw rod. An agricultural machine can include such a device.
