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, particularly relate to a kind of Motor train unit locomotive 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 catabiotic major part is all used to overcome air resistance during motor train unit run.
The marshalling of corresponding different headstock head dummy and tailstock head dummy, the air resistance of motor train unit is also different.From small to large marshalling is sorted successively according to aerodynamic drag: 1, single arch head car and two arch trailer.2, head, trailer are all and singly encircle capitiform.3, two arch head car and single arch trailer.4, head, trailer are all two arch capitiform.Wherein, single arch head car is minimum with two arch trailer aerodynamic drag, single arch head car is Streamline integrated, frontal resistance is little, and headstock front end nose cone has a down dip, and headstock lift alleviates headstock gravity effect, further reduction frontal resistance, two arch trailer nose cone is lifted, and tailstock eddy current is able to away from ground, thus reduces eddy resistance.As can be seen here, adopt the marshalling of single arch head car and two arch trailer, car load aerodynamic drag is minimum and tailstock safety is high, for best drag reduction is organized into groups.Run because motor train unit come and go, when return is run, procephalon car becomes trailer, and protocercal tail car becomes a car, and head car is again trailer simultaneously.The headstock front end of existing Motor train unit locomotive is fixedly connected with headstock rear end, and headstock can not convert head dummy, the marshalling that motor train unit can only adopt head, trailer is all single arch head dummy.
What head, trailer were all single arch capitiform is grouped in the marshalling that drag reduction aspect is inferior to single arch head car and two arch trailer, this marshalling is just simple uses a kind of headstock to reduce pressure drag before and after motor train unit, can not the drag reduction advantage of maximum performance single arch head car, and owing to failing to adopt two arch trailer to reduce tailstock eddy resistance, also reduce the safety of the tailstock.
Summary of the invention
The invention provides a kind of Motor train unit locomotive and motor train unit, to ensure 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 locomotive, comprise headstock front end and headstock rear end; Described headstock front end is provided with at least two different surfaces windward; Described Motor train unit locomotive comprises slewing arrangement, is arranged between headstock front end and headstock rear end, for realizing described headstock front end relative to described headstock rear end thereof, to realize the evolution on different surface windward.
The present invention also provides a kind of motor train unit, comprises two Motor train unit locomotive and multiple motor train unit carriage, and two Motor train unit locomotive divide the two ends being located at compartment, and wherein, Motor train unit locomotive adopts Motor train unit locomotive provided by the present invention.
Motor train unit locomotive provided by the invention and motor train unit, headstock front end can relative to headstock rear end thereof, realize the mutual conversion of single arch headstock and two arch headstock, solve the defect that cannot adopt single arch head car and the best drag reduction layout of two arch trailer when motor train unit come and go in prior art, reduce the overall operation resistance of motor train unit, and structure is simple, safety is high.
