5、11 Superseding J2580 MAR2011 Identification and Installation of Air Brake System Components RATIONALE J2580 has been reaffirmed to comply with the SAE five year review policy. 1. Scope This Recommended Practice covers air braked trucks, truck-tractors, trailers and buses. It enumerates the identifi

6、cation and installation of the air brake components not covered in other SAE recommended practices and standards. 1.1 Purpose To provide a functional means to maximize the potential for correct installation and maintenance of air brake system components for proper actuation and operation of the brak

7、ing system by providing a standard method of identification of air brake system valves, components and connections/ports. 1.2 Rationale This document is to be updated in keeping with the five year review process. The Truck and Bus Systems Committee has determined that no changes will be made at this

8、 time. 2. References 2.1 Applicable Publications The following publications form a part of this specification to the extent specified herein.

11、1 Components and valve port identification as defined in the SAE and/or ISO recommended procedures or standards pertaining to the respective components and valves shall be utilized. Those not covered in their respective standards will be compiled into this recommended practice at such time they are

12、 determined and it is deemed more effective for inclusion herein. 3.2 Air System Connector Fitting Identification 3.2.1 An optional recommendation is any connector fittings that remain fully in place when tubing is removed be color or functional identification (I.D.) number coded to assist in proper

13、 placement of the tubing when it is installed/replaced. This would apply to push-to-connect fittings as well as other equivalent connectors. Colors or functional I.D. numbers utilized are to correspond with the Supply, Control/Service, Delivery or Other function and/or tubing to which they connect.

14、3.3 Air System Air Line Identification 3.3.1 The various air brake systems and their basic components consist of supply, primary service, secondary service and emergency/parking. The following is a delineation of the terms used to describe the various systems and their respective definitions. These

15、are based upon the commonly used industry terms, FMVSS 121 and manufacturers literature for various air brake systems/components. _ SAE INTERNATIONAL J2580 NOV2016 2 of 53.3.1.1 Supply System The portion of the air system connecting the air compressor/source to the primary and secondary service air

16、systems. This includes the air lines connecting to charging, control or conditioning components that control pressure, clean and/or dry the charge air. This will include but not be limited to components such as the governor, air dryer, etc. Trailer supply lines are not included and should be per Tab

17、le 1 System Color-Function Number Coding. 3.3.1.2 Primary Service System The portion of the air brake system, reservoirs, lines and components/chambers/actuators that deliver air/force to the brakes and are designated by the manufacturer as the primary service system and are directly or indirectly c

18、ontrolled by the driver. 3.3.1.3 Secondary Service System The portion of the air brake system, reservoirs, lines and components/chambers/actuators that deliver air/force to the brakes and are designated by the manufacturer as the secondary service system and are directly or indirectly controlled by

19、the driver. 3.3.1.4 Emergency/Parking System The portion of the air brake lines, components and system that actuate the emergency and/or parking brake actuators/brake chambers and are designated by the manufacturer as the emergency or parking system and are directly or indirectly controlled by the d

20、river or by automatic operation. 3.3.1.5 Other This includes multiple components/systems that do not directly supply, control or actuate brake components. These can include but are not be limited to items such as the air suspension, fifth wheel slider, differential lock, etc. 3.3.2 AIR LINE COLOR 3.

21、3.2.1 System Color-Function Number Coding Table 1 This chart defines the colors of any nonmetallic tubing or coiled nonmetallic tubing to be utilized for the various accessories, brake components and brake systems for vehicles covered in the scope. It also defines the alternative functional identifi

22、cation numbers for individual valve ports such as supply, control, delivery, etc. 3.3.2.2 Nonmetallic Tubing Color Definition Table 2 This chart defines the means of standardizing individual colors utilizing typical color identification for the nonmetallic tubing and connectors. 3.3.2.3 Accessory ai

23、r lines may be any color so long as colors designated in Table 1 are not used except as follows: _ SAE INTERNATIONAL J2580 NOV2016 3 of 53.3.2.3.1 5/16 in Diameter Purple-violet or other colors may be used including the basic system colors of red, blue, light green, yellow or orange. It is recommend

24、ed light green and orange be used respectively for primary and secondary system dash gages. 3.3.2.3.2 3/8 in Diameter The basic system colors of red, blue, light green, yellow or orange may not be used. Purple-violet or other colors may be used. 3.3.3 AIR BRAKE HOSES Air brake hoses that are permane

25、ntly mounted and utilized for delivery only from an actuation valve to foundation brake(s) actuator do not need to be identified by color or otherwise. It is recommended that very long hoses such as on slide axle trailers be identified per Table 1 for correct connection to assure proper actuation an

26、d operation of the braking system. 4. Repair/Replacement 4.1 Repairs and/or replacement of components, connectors, air lines and/or electrical connections may be required for maintenance purposes. It is recommended that replacements should conform to the specified identification and/or color. 4.2 Wh

27、en the specified color connector and/or tubing is not available, black may be used for replacement with proper identification. The replacement must be identified using colored bands and/or numbers to help assure the continued proper actuation and operation of the braking system. See the Table 1 for
