Trailer truck with energy absorbing system - absorbs kinetic energy of trailer between chassis frame and front of trailer

摘要

The trailer truck comprises a trailer mounted at its front on the rear of a chassis frame of a tractor and energy absorbing system located between the chassis frame and a coupler of the trailer and adapted to allow an upward or forward movement of the coupler relative to the frame to absorb kinetic energy of the trailer upon collision. When a vehicle collides against the trailer of the trailer truck made according to the invention and the impact force acting onto the trailer exceeds a predetermined value, the trailer is moved forwardly relative to the tractor, but the kinetic energy of this moved trailer is absorbed by means of the energy absorbing system so that the impact force acting onto the trailer, which force exceeds the predetermined value, will not be directly transmitted to the tractor.
