Abstract
The invention provides a motor train unit locomotive and a motor train unit. The motor train unit comprises a locomotive front end and a locomotive rear end, at least two different windward surfaces are arranged at the locomotive front end, the motor train unit locomotive comprises a rotating device, and the rotating device is arranged between the locomotive front end and the locomotive rear end and used for achieving rotation of the locomotive front end relative to the locomotive rear end along the horizontal axis so as to achieve position changing of the different windward surfaces. The locomotive front end can rotate relative to the locomotive rear end so as to achieve mutual conversion of a single-arched locomotive and a double-arched locomotive. The motor train unit locomotive and the motor train unit overcome the defect that the motor train unit cannot adopt optimum anti-drag arrangement of the single-arched locomotive and a double-arched tail train in the prior art, reduce overall running resistance of the motor train unit, and are simple in structure and high in safety.
Description
Technical field
The present invention relates to motor train unit physical construction technology, relate in particular to a kind of motor train unit headstock and motor train unit.
Background technology
Along with improving constantly of motor train unit speed, the resistance of motor train unit also obviously increases, and wherein, air resistance occupies larger specific gravity, and motor train unit catabiotic major part in service all is used for overcoming air resistance.
The marshalling of corresponding different headstock head dummys and tailstock head dummy, the air resistance of motor train unit also is different.From small to large marshalling is sorted successively according to aerodynamic drag: 1, single arch car and two arch trailers.2, head, trailer are all single arch capitiform.3, two arches car and single arch trailer.4, head, trailer are all two arch capitiforms.Wherein, a single arch car is minimum with two arch trailer aerodynamic drags, a single arch car is Streamline integrated, frontal resistance is little, and headstock front end nose cone has a down dip, and headstock lift alleviates the headstock gravity effect, further reduce frontal resistance, lift on two arch trailer nose cones, tailstock eddy current is able to away from ground, thereby reduces eddy resistance.This shows, adopt the marshalling of single arch car and two arch trailers, car load aerodynamic drag minimum and the tailstock are safe, are best drag reduction marshalling.Because motor train unit come and go operation, during the return operation, the procephalon car becomes trailer, and former trailer becomes a car, and a car is again trailer simultaneously.The headstock front end of existing motor train unit headstock is captiveed joint with the headstock rear end, and headstock can not the conversion head dummy, and motor train unit can only adopt head, trailer to be all the marshalling of single arch head dummy.
Head, trailer are all the marshalling that the drag reduction aspect is inferior to single arch car and two arch trailers that is grouped in of single arch capitiform, this marshalling is just simple uses a kind of headstock to reduce motor train unit front and back pressure drag, drag reduction advantage that can not the single arch of a maximum performance car, and owing to failing to adopt two arch trailers to reduce tailstock eddy resistance, also reduced the safety of the tailstock.
Summary of the invention
The invention provides a kind of motor train unit headstock and motor train unit, to guarantee the best drag reduction marshalling of motor train unit, reduce the overall operation resistance of motor train unit.
The invention provides a kind of motor train unit headstock, comprise headstock front end and headstock rear end; Described headstock front end is provided with at least two different surfaces that facing the wind; Described motor train unit headstock comprises slewing arrangement, is arranged between headstock front end and the headstock rear end, is used for realizing that described headstock front end rotates with respect to described headstock rear end, to realize the evolution on the different surfaces that facing the wind.
The present invention also provides a kind of motor train unit, comprises two motor train unit headstocks and a plurality of motor train unit carriage, and two motor train unit headstocks divide the two ends that are located at the compartment, and wherein, the motor train unit headstock adopts motor train unit headstock provided by the present invention.
Motor train unit headstock provided by the invention and motor train unit, the headstock front end can rotate with respect to the headstock rear end, realize the mutual conversion of single arch headstock and two arch headstocks, solved the defective that can't adopt single arch car and the best drag reduction layout of two arch trailers when motor train unit come and go in the prior art, reduced the overall operation resistance of motor train unit, and simple in structure, safe.
