Abstract
The invention relates to a bogie for a railway vehicle, having a bogie frame formed of hollow profiles, wherein the bogie frame is at least partially filled by a latent storage material having a phase change temperature above 0 DEG C.
Description
Technical field
The present invention relates to a kind of bogie truck for guideway vehicle, it has truck frame, and described truck frame is formed by hollow profile.
Background technology
In the winter operation of guideway vehicle, snow and ice can accumulate on the truck frame in a large number, and adhesively rests on the described truck frame.The gathering of such snow can increase into drop at any time a glob of on the track bed during the travelling of guideway vehicle.The member on back to back bogie truck in said case, produces the danger that the back to back bogie truck of guideway vehicle rolls away from the snow group of freezing, to such an extent as to can damage or even come off fully.Described member can be compressed air piping, electrical lead, antenna etc.
The up to now following solution of problem that snow gathers at truck frame: bogie truck is manually removed snow and ice at a certain time interval.Be alternative in this, also have the deicing equipment that is used for guideway vehicle.Also possibly respectively bogie truck is sprayed with deicing agent.Yet, following difficulty appears when using deicing agent, that is and, described deicing agent is only vehicle adhesion for example 15 minutes and lose subsequently its effect.
Summary of the invention
Based on this, the purpose that the present invention is based on is, proposes a kind of bogie truck, reduced the in the winter time accumulation of snow and ice in service in described bogie truck.
Described purpose realizes by the truck frame of filling with latent heat storage material at least in part, and the phase transition temperature of described latent heat storage material is more than 0 ℃.
Described latent heat storage material has following characteristics, and irrelevant with the heat that has received, the temperature of latent heat storage material does not change in the scope of phase transition temperature.
This means, for example be 15 ℃ temperature when bogie truck has been heated to by day, and described temperature along with the night that arrives when reduction, the temperature of bogie truck irrespectively remains unchanged in the scope of determining with outside cooling.In fact this mean, when being lower than the scope of latent heat, even under negative external temperature, bogie truck also just reaches the temperature under the solidfying point.
The phase transition temperature of latent heat storage material is preferably between 2 ℃ and 7 ℃.By this way, reduced significantly freezing or the accumulation of snow on described bogie truck of bogie truck.
Latent heat storage material can exist with the form of micropackaging, and wherein, shell dimension can be less than 1mm, yet also can be in several millimeters the scope.
Bogie truck preferably has at least one traction motor, and described traction motor is arranged so that latent heat storage material can heat by the cooling-air that has heated of traction motor.At this, heat for example is delivered to the latent heat storage material from cooling-air by truck frame.
Bogie truck has the filling mouth for latent heat storage material, so that the cavity of described bogie truck can be filled by described material.In order to monitor the material level of bogie truck, described bogie truck can have the control mouth.
In order to fill the cavity of bogie truck, can use in principle every kind of latent heat storage material that satisfies the above-mentioned boundary condition that is used for phase transition temperature.Yet what can mention as an example is the salt liquor of paraffin, aliphatic acid or eutectic, and wherein, the paraffin of micropackaging can have been bought at least.
The specific embodiment
The below will illustrate embodiments of the invention.
Bogie truck is formed by hollow profile at least in part, and wherein, already present cavity is to outer closure.In order to fill truck frame, be provided with in place and fill mouth, described filling mouth is positioned on the end of truck frame in an advantageous manner.There is the control mouth in the opposed end of truck frame, can monitors the material level of truck frame by means of described control mouth.Fill truck frame to be used for resisting corrosion with nitrogen.After filling truck frame with latent heat storage material, fill remaining cavity in the bogie truck section bar with nitrogen.
In especially in the winter time, the temperature of truck frame is not less than 3 ℃ and be higher than by day 3 ℃ of accumulations to avoid avenging at night, with hot air from the bogie truck the traction motor cooling mechanism or also additionally be directed on the truck frame from AuCT.In the winter time, the hot air in traction motor can for example still be positioned at 60 ℃, is 0.6m at charge air or rather
3In the situation of/s.The permeability of heat of the steel by can making described truck frame, heat can further distribute in framework.In this way, the temperature in the truck frame rises to more than 3 ℃.At night, when external temperature below 3 ℃, latent heat storage material crystallization, and discharge the heat store.If the complete crystallization of latent heat storage material, the temperature of truck frame will further reduce so.
Latent heat storage material exists with the form of micropackaging, and wherein, particle size can be between several 100 μ m to 10mm.
Latent heat storage material especially can be paraffin, aliphatic acid or eutectic salts solution, and its phase transition temperature between state of aggregation solid and liquid should be between 2 ℃ and 6 ℃.
