Description
Technical field
The utility model belongs to energy absorption device technical field, more particularly to a kind of anti-creep energy-absorbing for the vehicles is filled
Put.
Background technology
In recent years, with the fast development of the vehicles especially rolling stock, the travel speed of train is greatly increased, to the greatest extent
Pipe employs many active measures, but still can not prevent the generation of train collision accident completely, therefore passive safety feature is to carrying
The passive safety of high train is significant.The energy absorption device of train end is the important composition of train passive safety feature
One of part, the mechanism of action of energy absorption device is to be collided by occurring effectively controllable plastic deformation effectively to absorb train
When impact kinetic energy, so as to lift safety concerns.When being also equipped with being used to prevent train collision in energy absorption device front end simultaneously
The anticreeper of vertical skew occurs for energy absorption device, so as to reduce the risk climbed car and toppled.
The anti-climbing energy-absorbing device installed at home on train at present is most of only comprising two kinds of knots of anti-creep tooth plate and energy absorbing tube
Structure, this apparatus structure is simple, is readily produced and safeguards, but does not possess the independent structure for resisting stronger vertical bending,
Once vehicle is collided with higher kinetic energy, easily cause the vertical flexing unstability of energy absorbing tube, so as to largely effect on energy absorbing tube
Crumple energy-absorbing effect, eventually results in compartment and climbs the serious consequences such as compression failure evil idea.In order to improve overall bending resistance, above-mentioned class
The device of type can only realize by the thickness or the strength of materials of increase energy absorbing tube, but this can dramatically increase production cost and
Construction weight.Therefore, the overall bending resistance and energy-absorbing that how rationally to set and improve Anti-creeping energy absorbing structural to improve device are imitated
Fruit turns into an important topic in current track traffic passive security field.
Utility model content
Based on above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model be to provide it is a kind of vehicle with
Larger kinetic energy occurs still possess preferable bending resistance and energy-absorbing effect stable anti-climbing energy-absorbing device during impact, to solve
The problem of traditional vertical bending resistance of anti-climbing energy-absorbing device is not enough in rail vehicle passive security field, absorbing energy capacity is small.
