Definitions

  • the invention relates to a collision protection device for track-guided city vehicles that are at the vehicle ends is arranged in the area of the vehicle head and from a bumper by two reversible shock absorbers is worn and with a tear-off connection and one subsequent guide is provided and from a deformable Stem exists.
  • Track-guided city vehicles are much more common involved in accidents as vehicles on railway lines, which is why there is a particular need for action regarding improvement collision protection.
  • partner protection should be considered as it is common are accidents with other road users. From accident analyzes is known that the existing solutions for collision protection is not sufficient. This relates on accidents with all road users.
  • a device is known from DE 38 18 839 C2 which is a removable head of a middle buffer coupling against one comprehensive space protection rod is replaced.
  • the room protection bar is by a swivel lock at the ends established.
  • the device described is based on the same principle according to DE 39 31 171 C2. The difference is in the solution of the swivel lock.
  • a disadvantage of this principle is that after exhausting the stroke of the shock protection Device hinders deformation of the stem as it cannot be moved out of the deformation zone.
  • Another disadvantage is that in the event of an eccentric impact, the when colliding with passenger cars according to accident analyzes the most common case is a reversible energy intake the centrally located clutch cartridge due to the high Moments is hardly possible.
  • a facility is from practice known, executed on the tram Dresden type NGT6 DD, in which a space support is carried by two shock absorbers becomes. This solution also has the problem that the collision protection device after exhausting the stroke, the deformation with special needs.
  • the invention is based on the problem of a collision protection device for track-guided city vehicles create, which overcomes the disadvantages of known solutions, by allowing local deformation in the front area and the impact on vehicle and occupants in the collision reduced with other road users.
  • the collision protection device consists of a bumper that is carried by reversible shock absorbers.
  • the shock absorbers extend beyond the structure by the length Y. This results from the stroke Z and the demolition distance Q.
  • the shock absorbers absorb collisions with low kinetic energy.
  • the tear-off connections fail.
  • the fixed part of the shock absorber whose length W results from the desired deformation path X of the stem and the tear-off path Q, pushes into the guides, the length T of the free space behind the tear-off connection being as great as the length W of the fixed part of the shock absorber , As a result, the bumper retreats almost without power and guided.
  • the forces are only introduced into the stem, which can deform directly from the front.
  • this can be preceded by a deformation element, the bumper then having to protrude by the length Y plus the deformation path V of the deformation element.
  • the length W of the fixed part of the shock absorber and the length T of the free space of the guides then result from the deformation path X of the stem, the tear path Q and the deformation path V of the deformation element.
  • the tear-off connection on the shock absorbers and the subsequent powerless guidance ensure that the stem can deform undisturbed in the front area.
  • the bumper By arranging the bumper below the stem, it can be deformed directly on the front after the shock absorbers have been torn off. Thanks to the additional deformation element in front of the stem, collisions with vehicles whose protruding structure lies above the bumper can be absorbed up to a certain kinetic energy without deformation of the stem.
  • a batten 1 of shock absorbers 2 is worn.
  • the shock absorbers 2 are on one Tear-off connection 3 fixed, e.g. screwed.
  • the tear-off connection 3 is in a guide 4 and is with a shear collar attached to its flange.
  • a stem 5 and the guide 4 open into a vehicle structure 6, which in the drawing is indicated schematically.
  • the bumper 1 is pushed back by a stroke Z of the shock absorbers 2, after stroke Z is exhausted, the force increases and the Shear collar of the tear-off connection 3 shears on the flange of the guide 4 from.
  • the bumper 1 is around a demolition path Q shifted.
  • the fixed part of the shock absorber 2 is the length of the tear-off path Q plus the deformation path X moved into the guides 4.
  • Figure 2 is a variant is shown in which an additional deformation element 7 is arranged in front of the stem 5.
  • the bumper 1 stands out by a length Y plus deformation path V.
