Description
Technical field
The present invention relates to technical field of rail traffic, more particularly, it relates to a kind of rail vehicle stucco system, further relate to
A kind of rail vehicle.
Background technology
Rail traffic vehicles are typically provided with stucco system, by controlling compressed air, can make the sand grains within sandbox
Outwards blown out by sand sprayer, fall between wheel track, improve the adhesion coefficient between wheel track, effectively suppression, minimizing wheel are empty
Turn or slide, improve the traction of rail vehicle, braking ability it is ensured that transport capacity and traffic safety.
Existing stucco control model is based on car control formula, is provided only with a set of on a whole section locomotive or permutation vehicle
Stucco control module, includes control valve and air pipe line etc.；Inventor finds, existing stucco control model also has one
Fixed shortcoming, is mainly manifested in：
When locomotive or vehicle travel need stucco when, control compressed air to flow to turning under car by control valve and air pipe line
To frame, and in the position needing, the grains of sand are oriented blowout；Yet with the uniformity of pipeline and control, and because different are spread
Sand position intermediate duct length is different, and the resistance that pipeline trend causes is different, result in：Bogie need to carry out identical lower sand work
The position made, under its sand sprayer, sand sand amount has differences；If the stucco amount adjusting the stucco pipeline of wherein a certain position is (as led to
Size is blocked up in contracting on toning homogeneous tube road) because internal duct resistance there occurs change, also can affect connected another in turn
The stucco amount of one position.I.e. the stucco amount of diverse location affects each other each other, and adjusting stucco amount wastes time and energy.
In sum, the sand sprayer work system stucco control how efficiently solving existing rail vehicle outfit is inaccurate
Really, and the problems such as be difficult to stucco amount that specific aim adjusts a certain position, it is current those skilled in the art asking of being badly in need of solving
Topic.
Content of the invention
In view of this, first purpose of the present invention is to provide a kind of rail vehicle stucco system, and this rail vehicle spreads
The sand sprayer work system stucco control that the structure design of sand system can efficiently solve existing rail vehicle outfit is inaccurate,
And the problems such as be difficult to the stucco amount that specific aim adjusts a certain position, second object of the present invention is to provide a kind of inclusion above-mentioned
The rail vehicle of rail vehicle stucco system.
In order to reach above-mentioned first purpose, the present invention provides following technical scheme：
