Provided is a collision energy absorbing apparatus capable of mitigating loads to the car body proper, passengers and the like by adding a structure combining a prescribed static strength and collision energy absorption performance to an energy absorbing body of the collision energy absorbing apparatus. In a limited inner space of a car body, a cover 80 that covers energy absorbing bodies 51, 52 combines a prescribed static strength and collision energy absorption performance. The cover 80 prevents irregularities, such as the breakage of cylindrical bodies of aluminum alloy, i.e., the energy absorbing bodies 51, 52 in each of the stages of transportation, storage, assembling and the like of the collision energy absorbing apparatus 50. The cover 80 having static strength fulfills the role of withstanding a prescribed static load and in the event of a collision against an obstacle, the cover 80 is broken earliest and reduces a peak load of crush, with the result that part of the collision energy is used in the breakage of the cover 80. As a result of this, the cover 80 can contribute to the absorption and mitigation of the collision energy.

An energy-absorbing device, particularly for a shock absorber of a track-guided vehicle, has an energy-absorbing element designed as a deformation tube and a counter element which interacts with the deformation tube such that upon a critical impact force being exceeded, the counter element and the deformation tube exhibit a relative movement toward one another while at least a portion of the impact energy introduced into the energy-absorbing device is simultaneously absorbed. For the energy absorbtion to take place according to a predictable sequence of events when force is introduced non-axially into the energy-absorbing device, the counter element is connected to the deformation tube by means of a form-fit connection circumferential to the deformation tube so as to prevent twisting of the counter element relative the deformation tube.

The invention provides a shock absorbing structure capable of turning the function of the shock absorber on and off according to the level of shock during collision, thereby reducing the frequency of replacing shock absorbers. On a rear surface of a load operating unit 11 constituting a shock absorbing device 10A are attached a load transmitting shaft 12 and a shock absorber 13. The load transmitting shaft 12 is passed through the center of the shock absorber and is connected to a supporting unit 14 via a pin 15 that extends toward the radial direction. The rear end of the shock absorber 13 faces the supporting unit 14 with a clearance therebetween. The pin 15 has notched grooves 21 formed thereto. When small load is applied, the load is transmitted from the load operating unit 11 through the load transmitting shaft 12, the pin 15 and the supporting unit 14 to the main body, so that the load is not applied on the shock absorber 13. When large load is applied, the pin 15 breaks from where the notched grooves 21 are formed, by which the surface of the closing plate 17 collides against the supporting unit 14, so that the load is transmitted to the shock absorber 13 and the shock is absorbed effectively.
