Abstract
The invention discloses a kind of multistage collision energy-absorbing pilots of deployable and collapsible.Troubleshooting device assembly includes pilot, fixation member, regulating member, and pilot front end is provided with multistage collision energy-absorbing structure, can solve the collision energy-absorbing problem of the pilot；Fixation member is mounted on EMU head vehicle and trailer, and regulating member is mounted on EMU head vehicle and trailer, and pilot is mounted in fixation member.Wherein, regulating member can be such that pilot rotates around fixing axle, to complete the folding and unfolding work of the pilot.According to the above measure, the collision energy-absorbing problem of pilot can be not only well solved, but also can reduce the air drag in EMU operational process.The present invention has collision energy-absorbing good, and structure is simple, the too small advantage of design margin.
Description
Technical field
The present invention relates to motor-car pilot technical fields, more particularly to a kind of multistage collision energy-absorbing troubleshooting of deployable and collapsible
Device.
Background technique
Pilot is mounted in the component of EMU head vehicle and trailer bottom, for removing the barrier on track, avoids
Barrier enters vehicle bottom, causes the damage of equipment and truck components under vehicle.For current pilot structure, substantially may be used
It is divided into two kinds, one is integral structures, are integrally attached on car body, and this kind of pilot does not have the effect of collision energy-absorbing, no
It is enough to protect the safety of equipment and truck components under vehicle；It is another then be the pilot with large-scale endergonic structure, energy-absorbing grade
It is not higher, but overgenerous collision will not generally occur for pilot, so this structure will cause design margin surplus, and
Its structure is complex, erroneous for installation, and manufacturing cost is excessively high.
In addition, air drag, which becomes, restricts the main of the EMU speed of service with the continuous promotion of EMU speed
One of factor, in the process of running, EMU need to consume big energy and overcome air drag, solve the problems, such as that this is main at present
Means be headstock shape is optimized, but we should also consider influence of other body apparatus to air drag, so
The present invention selects pilot for design object.Existing EMU head vehicle is consistent with trailer moulding, and pilot is fixedly mounted on bottom
Portion, in operational process, the pilot on trailer does not play troubleshooting, will increase the air drag of motor-car instead, influences motor-car
The speed of service.
Therefore, current pilot technical field be badly in need of it is a kind of not only need to solve the problems, such as collision energy-absorbing, and can subtract
The pilot of small air drag.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of multistage collision energy-absorbing pilot of deployable and collapsible, it not only can be real
The collision energy-absorbing of existing pilot, and can reduce EMU suffered air drag in the process of running.
The technical solution of the invention is as follows is achieved:
A kind of multistage collision energy-absorbing pilot of deployable and collapsible, including outside level-one energy-absorption box, energy-absorption box gusset, energy-absorption box
Shell, second level energy-absorption box, troubleshooting body, I component of hinge seat, holding screw I, hinge seat I, regulating member, connecting rod, hinge joint,
Hydraulic cylinder, piston rod, II component of hinge seat, hinge seat II, support base, pin III, car body, pin II, stud, opening
Pin, pin I, it is characterised in that the level-one energy-absorption box is made of multiple energy-absorption box gussets, energy-absorption box shell, and setting can receive
The multistage collision energy-absorbing pilot front end for putting formula, is welded on troubleshooting body；After four second level energy-absorption boxes follow level-one energy-absorption box closely
It is arranged symmetrically, is welded on troubleshooting body, fixed and separated by beam between two-level configuration；I component of hinge seat by holding screw I,
Hinge seat I forms, and hinge seat I is fixed on troubleshooting body with holding screw I；Regulating member is by connecting rod, hinge joint, hydraulic
Cylinder, piston rod composition, hydraulic cylinder push on the central axes that screw is fixed on car body by changing cylinder pressure oil oil inlet direction
Piston rod stretches along the vehicle body direction of EMU, contract and pressure maintaining is parked, and the piston rod other end is threadedly coupled with hinge joint, connecting rod
One end pin II forms revolute pair with I component of hinge seat, and pin II is axially positioned with stud, connecting rod other end pin
I forms revolute pair, the axial opening finger setting of pin I with hinge joint；II component of hinge seat is by hinge seat II, support base, pin
III composition of nail, a pair of of hinge seat II is fixed on the car body by screw, and a pair of of support base is fixed on troubleshooting body by screw, symmetrically
It is arranged in hydraulic cylinder) two sides, hinge seat II and support base the composition revolute pair of pin III；Troubleshooting body can be around a pair of of III axis of pin
Line rotation pushes piston rod to stretch, contract, parked, the realization of troubleshooting body is made to pack up, put down, is parked by control hydraulic cylinder oil inlet；One
The multistage collision energy-absorbing pilot of kind deployable and collapsible is mounted on the central axes of EMU head vehicle and trailer.
Compared with prior art, it is an advantage of the invention that it will be apparent that being mainly manifested in:
1, a kind of multistage collision energy-absorbing pilot of deployable and collapsible provided by the invention has multistage collision energy-absorbing structure, can
To meet the collision energy-absorbing requirement of pilot, but it is unlikely to cause the problem of design margin surplus.
2, by the movement of regulating member and toggle-action lever, entire pilot component movement can be driven, pilot is completed
Folding and unfolding work, to reduce air drag suffered when EMU operation.
