The invention relates to an energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle, comprising a plug that has a longitudinal axis and a mandrel that has an opening, whereby the plug is arranged to be moved at least partially through the opening, if a force pointing in the longitudinal axis is applied to the plug, and whereby at least a part of the plug—especially its hull—is deformed, when the plug is at least partially moved through the opening, whereby said hull being at least partially deformed, when the plug is at least partially moved through the opening. The hull is attached to the rod by clamping or fixing with fasteners, preferably with protrusions around the rod and/or at least one plug or nut. The hull is a relatively independent element which can be put over a rod and therefore the hull can be mounted or unmounted subsequently to a rod without influencing the stability or main function of the connection device.

A deformable element includes a profiled tube having a rectangular cross-section, and a plate which closes the profiled tube at one end, where a bracket is fastened between opposite sides of the profiled tube at the end of the profiled tube that is closed by the plate.

An energy absorption device configured to be provided at a front end of a train includes a coupler seat, a support base, a crush pipe, a coupler, a guide member, an energy absorption component and an anti-climbing assembly. The support base is fixedly arranged at the front end of the train; the crush pipe is fixed to the coupler seat; a connecting end of the coupler is inserted into the crush pipe and is slidable with respect to the crush pipe; the guide member has one end fixed to the coupler seat, and another end inserted into the support base and slidable with respect to the support base; the guide member limits an oscillation of the crush pipe; the energy absorption component is provided between the coupler seat and the support base; and the anti-climbing assembly is fixedly arranged on the support base and is compressible.

An energy absorption device absorbs energy that is released upon impact between two objects in relative motion. An exceptional load applied to any of the two objects results in acceleration of one object relative to the other object. The acceleration energy is absorbed by deformation of an element or elements that are put under stress from the objects upon impact. The process of deformation includes a controlled diameter reduction during a forced elongation of a semi-solid or solid deformation bolt made from a cold-formed material in the direction of force generated from the acceleration.

An energy absorbing device has a rod with a part, suitable for cutting by means of surrounding cutting tools mounted in a body sleeve and oriented to the inside. In addition, the rod has an angular guiding part passing into the part suitable for cutting and is pivoted in a support, wherein the body sleeve with the attached cutting tools is connected by breakable elements with the support.

A rail car includes an elongated floor supporting a rail car body, a draft sill depending from the floor, and a crash energy management (CEM) system. The CEM system includes a coupler plate coupled to the draft sill and depending from the floor between the draft sill and a first end of the floor, a coupler support depending from the floor between the coupler plate and the first end of the floor, an elongated coupler assembly extending from the coupler plate in a direction of the first end of the floor via an opening defined by the coupler support, and at least one cable connected in tension between the coupler support and the coupler plate.
