Description
Technical field
The utility model belongs to railcar headstock field, more specifically to a kind of railcar integral composite vehicle
Head.
Background technology
With the continuous improvement of EMU speed, the resistance of EMU will significantly increase, when EMU speed reaches
During 200km/h, air drag accounts for 70% or so of operation drag overall, and when EMU speed reaches 300km/h, air drag accounts for
Run 85% or so of drag overall.The major part of energy consumed in EMU operation is all used for overcoming air drag.
At present, the head vehicle of EMU uses similar body of revolution moulding, leaves for terminal from inception point as trailer moulding
When standing, head vehicle is preceding, and trailer is rear, and when returning to former inception point by terminus, procephalon vehicle becomes trailer, and protocercal tail vehicle becomes head vehicle.Dynamic
In vehicle group driving process, since trailer can generate vortex, cause EMU tail portion resistance very big, EMU is made to consume in operation
A large amount of power.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of railcar entirety composite woods
Truck head, reasonable design can be general in head vehicle and trailer, and the design of preceding streamline wind guide tank and rear streamline wind guide tank can be realized
The flowing of air-flow avoids generating vortex, so as to reduce the running resistance of EMU, reduces the power consumption of EMU, together
When, the enamel layer surface of composite plate is smooth, and windage is small, and has good heat-insulated and flame retardant effect, highly practical, suitable for pushing away
Extensively.
To achieve the above object, the utility model provides following technical solution：
A kind of railcar integral composite headstock, it is characterised in that：It is surrounded jointly including point, top surface and both walls
And in streamlined；Preceding streamline wind guide tank and rear streamline wind guide tank are symmetrically arranged in the both walls；The top surface is in streamlined；
Cavity is provided at the top of the top surface, be provided in cavity it is several from front to back through design ventilation holes, ventilation hole it is interior
Enamel layer is coated on side；The point, top surface and the both walls composite plate made of composite material form；It is compound
Plate includes sandwich layer, is disposed with thermal insulation layer and enamel layer on the upper surface of sandwich layer from inside to outside, on the lower surface of sandwich layer in
It is disposed with flame-retardant layer and enamel layer outward；Several grooves, and thermal insulation layer are respectively arranged on two surfaces of the sandwich layer
Be provided with protrusion on the side of flame-retardant layer, protrusion be plugged into groove realize it is preferably fixed.
As a kind of technical solution of optimization, the cavity is made of stainless steel material, and cavity is pacified by bolt
At the top of top surface.
As a kind of technical solution of optimization, the sandwich layer is the sandwich layer made of steel material.
As a kind of technical solution of optimization, the thermal insulation layer is the ceramic thermal barrier layer being made of ceramic materials；The resistance
It is the flame-retardant layer made of high-strength abrasion-proof flame-retardant polycarbonate material to fire layer.
By adopting the above-described technical solution, compared with prior art, the utility model is designed reasonably can be general in head
The design of vehicle and trailer, preceding streamline wind guide tank and rear streamline wind guide tank can realize the flowing of air-flow, avoid generating vortex, so as to
The running resistance of EMU is reduced, reduces the power consumption of EMU, meanwhile, the enamel layer surface of composite plate is smooth, wind
Hinder it is small, it is highly practical and with good heat-insulated and flame retardant effect, suitable for promoting.
The utility model is described further with reference to drawings and examples.
Description of the drawings
