| 释义 |
A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer,[1] or from a locomotive to railway air brakes on railroad cars.[1] Gladhand connectors resemble a pair of "hands shaking" when interlocked, hence the name.[2] DesignGladhands are designed to allow the driver to disconnect without a mechanic or tools.[2] They sometimes utilize a quick release style to speed up brake release time.[2] A tractor / trailer typically has two gladhands - one for service brakes and another for emergency brakes.[3] Gladhands are color coded. In North America, service lines are blue and emergency brake lines are red and are standardized by SAE International's standard SAE J318.[4] Outside North America, the supply lines are red and the control lines are yellow, following International Organization for Standardization's standard ISO 1728.[5] The SAE "service" lines are synonymous with the ISO "control" lines and the "emergency" lines are synonymous with ISO "supply" lines. Mated rubber grommets provide a positive seal.[6] Joined halves separate automatically when depressurized.{{citation needed|date=July 2015}} Gladhand couplers are typically genderless or hermaphroditic,[2] allowing them to be freely connected to each other, for example allowing either end of a railcar to be connected to the end of a train. North America has a system of standardized gladhand sizes.[2] References1. ^{{cite book|last1=Pitt|first1=John|title=USA by rail : plus Canada's main routes|date=2012|publisher=Bradt Travel Guides|location=Chalfont St. Peter|isbn=184162389X|page=29|edition=8th}} {{Commons category|Palm couplings|position=left}}2. ^1 2 3 4 5 {{cite book|last1=Bennett|first1=Sean|title=Modern diesel technology: brakes, suspension, and steering|date=2007|publisher=Thomson Delmar Learning|location=Clifton Park, NY|isbn=1418013722|page=54|url=https://books.google.com/books?id=GhnCCAAAQBAJ&pg=PA54&dq=gladhand&hl=en&sa=X&ved=0ahUKEwi898uNrtbJAhWCTSYKHQMLCfAQ6AEINzAC#v=onepage&q=gladhand&f=false|accessdate=December 12, 2015}} 3. ^{{cite book|last1=Byrnes|first1=Mike|last2=Publishers|first2=Associates, Inc.|title=Bumper to bumper : the complete guide to tractor-trailer operations.|date=2003|publisher=Mike Byrnes and Associates|location=Corpus Christi, TX|isbn=0962168769|page=165|edition=4th|url=https://books.google.com/books?id=IaPxkJE3C6EC&pg=PA165&dq=gladhand+trailer&hl=en&sa=X&ved=0ahUKEwjgi7K_tdbJAhWCTSYKHQMLCfA4FBDoAQguMAA#v=onepage&q=gladhand%20trailer&f=false|accessdate=December 12, 2015}} 4. ^https://saemobilus.sae.org/content/j318_196711 5. ^http://www.iso.org/iso/catalogue_detail.htm?csnumber=44103 6. ^{{cite book|last1=Knapp|first1=Gordon J.|title=Is Over the Road Trucking for You?|date=2011|publisher=AuthorHouse|isbn=1463403321|page=193|edition=Second|url=https://books.google.com/books?id=Oq0G5-rGJb8C&pg=PA193&dq=gladhand+rubber&hl=en&sa=X&ved=0ahUKEwjdxpvUt9bJAhXF7yYKHfr3DY8Q6AEILzAA#v=onepage&q=gladhand%20rubber&f=false|accessdate=December 12, 2015}} 1 : Pneumatics |
