Description
Technical field
The invention belongs to locomotive brake fields, and in particular to a kind of locomotive braking system.
Background technology
Locomotive is the common vehicles in daily life.The braking of locomotive is completed by braking system.Braking
System is also referred to as braked, and running locomotive, vehicle and other means of transports or machinery etc. is instigated to stop or lower speed
Action.The General Principle of braking is that a brake wheel or brake disc are fixed on the high speed shaft of machine, is installed therewith on engine base
Adaptable brake shoe, band or disk is allowed to generate braking moment under external force.
Braking system has disc brake at present and drum brake also has pneumatic brake, and more cooked vehicle is all much drum after shroud, now
Vehicle it is many front and back be all disc brake.Because disc brake is compared with the good heat dissipation of drum brake, under high speed on-position, it is not easy to generate heat and decline
It moves back, so its high speed good braking effect, but in low-speed cold brake, braking effect is not so good as drum brake, and price is more expensive than drum brake.So now
Many intermediate cars use full brake, and general car rouses after using shroud, and relative low speeds, and the card for needing brake force big
Vehicle, bus still use drum brake.
Disc type brake disc (dish) is divided into solid disc (monolithic disk) and air duct disk (biplate disk).Solid disc type we be easier
Understand, it is plainly, exactly solid.Air duct disk (Vented Disc), as the term suggests have ventilative effect, in terms of appearance, it
There are many hole skies for leading to the center of circle, referred to as air duct on circumference.Automobile, by cross-ventilation at air duct, reaches heat dissipation in enforcement
Purpose, it is more better than solid formula heat dissipation effect.Most of car is all forerunner, and the abrasion of shroud frequency of use meter is larger, therefore adopts
With primary air separating duct disk, rear solid disc (monolithic disk).Certainly it is all air duct disk also to have front and back, but manufacturing cost can't difference from
Spectrum.
Existing braking system has the following disadvantages:Cause air duct disk into water freezing under the conditions of sleet microthermal climate
When, braking function can fail, and locomotive brake is unable to normal use.
Currently, using, percussion makes air duct disk icing fragmentation or pouring hot water makes the modes such as air duct disk ice-out thaw, existing
Some thawing modes are very inconvenient.
Invention content
The purpose of the present invention is to provide a kind of locomotive braking systems, inconvenient to solve to thaw after existing air duct disk freezes
The problem of.
The present invention base case be:A kind of locomotive braking system, including rack and with the fixed air duct of locomotive wheel

When ice and snow is attached on the disk of air duct when well, especially, hot wind can not only act on ice and snow surface, additionally it is possible to act on ice and snow and wind
The one side of road disk contact substantially increases effect, the efficiency for eliminating ice and snow to fall off conducive to ice and snow large area.
Further, air duct disk is circumferentially evenly equipped with several grooves.
Advantageous effect:The setting of groove is flowed convenient for rainwater or the ice and snow of thawing and is got rid of with the rotation of air duct disk
From air duct disk.
Further, safe unit is two and is symmetrically distributed in the both sides of air duct disk.
Advantageous effect:Increase the active area of safe unit so that cooling or elimination of the safe unit to air duct disk
Ice and snow and other effects greatly promotes.
Further, further include air bag and with the co-axially fixed push plate of valve plate, push plate is located at outside Y-piece, air bag one end with
Rack is hinged, and the air bag other end is hinged with push plate.
Advantageous effect:When outside air temperature rises, air bag expands to push push plate to rotate forward, so that valve plate is just
To swing, the first vortex tube is connected to appendix, to air duct disk blowing cold air, cool down to air duct disk;When extraneous gas
When temperature declines, balloon contraction is to drive push plate to rotate backward, so that valve plate backswing, second eddy current pipe and appendix
Connection, to blow out hot wind to air duct disk, ice and snow is generated on pre- air shaft disk or be eliminated to the ice and snow on the disk of air duct.
