Claims15
A device for preventing jackknifing using a magnetic damping coupler of a tractor, comprising:
- a coupler body disposed on a tractor and having a guide king pin of a trailer inserted therein;
- a cylinder disposed in the coupler body and filled with Magneto-Rheological (MR) fluid;
- a piston disposed in the cylinder to be able to be fastened to the guide king pin, having a flow aperture in which the MR fluid flows, and having electromagnetic coils that generate magnetic fields in the flow aperture when a current is applied;
- and
- a controller configured to apply a current to at least one of the electromagnetic coils in response to determining that jackknifing of the tractor and the trailer has occurred.
