This standard replaces the standard previously issued as follows. - GB/T 13061-1991. Technical specification of air spring used for air suspension of commercial vehicle1 ScopeThis standard specifies the technical requirements and test methods for air spring products for the air suspensions of commercial vehicles. This standard applies to the air suspensions of commercial vehicles. The air springs for other non-air suspension, non-commercial vehicles or non-vehicle may make reference to this standard.2 Normative referencesThe following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard. GB/T 528 Rubber, vulcanized or thermoplastic - Determination of tensile stress-strain properties GB/T 531.1 Rubber vulcanized or thermoplastic - Determination of indentation hardness - Part 1.Durometer method (Shore hardness) GB/T 1682 Rubber, vulcanized - Determination of low-temperature brittleness - Single test piece method GB/T 2941 Rubber - General procedures for preparing and conditioning test pieces for physical test methods GB/T 3512 Rubber, vulcanized or thermoplastic - Accelerated ageing and heat resistance tests GB/T 7759 Rubber, vulcanized or thermoplastic - Determination of compression set at ambient elevated or low temperatures3 Terms and definitionsThe terms and definitions as defined in GB/T 34591 as well as the following terms and definitions apply to this document. 3.1 Air spring height The distance between the upper and lower support planes for installation of the air spring. 3.2 Standard height A reference height of the air spring, which is used as the start point for the calculation of deformation. 3.3 Design height The installation height of the air spring at the design location of vehicle is referred to as the design height Hd. 3.4 Standard pressure The static pressure at which the air spring is subjected to the rated load at a standard height. 3.5 Maximum pressure pmax The static pressure at which the air spring is allowed to be subjected to the maximum load at standard height. 3.6 Standard status The working status of the air spring at standard height and standard pressure.4 Technical requirements4.1 Technical requirements for air spring assembly 4.1.1 The general use temperature of the air spring is -30 °C ~ 57 °C. For the air springs which have special use requirements (such as beyond this temperature range, oil resistance, etc.), it is determined by the supplier and the user through negotiation; and it is permanently identified on the air spring. 4.2 Technical requirements for each component of air spring 4.2.1 The physical-mechanical properties of the rubber compound of air spring’s bellow may be found in Appendix A. 4.2.2 The appearance quality of each component of the air spring shall meet the following requirements.5 Test methods5.1 Test items The rubber compound for bellow shall be subjected to physical-mechanical property test. The air spring is subjected to airtightness test, elastic-property test, volume test, destructive, frame fatigue test. 5.2 Test sample 5.3 Test conditions The ambient temperature of the test of finished product of air spring assembly shall be controlled at (23 ± 5) °C. 5.4 Test equipment 5.4.1 The air spring’s elastic-property test is carried out on an electro-hydraulic servo or mechanical test machine which can perform approximate harmonic motion. Record the load-deformation and pressure-deformation correspondence. 5.5 Test procedure 5.5.1 Physical-mechanical property test of rubber compound The physical-mechanical properties of the rubber compound used to make the bellow are as shown in Appendix A. 5.5.2 Airtightness test Adjust the air spring to the standard height. Inflate to 1.3 times the standard pressure. Hold for 30 s. After it stabilizes, reduce the pressure of the air spring to the standard pressure. Close the inflation and exhaust valves. Record the pressure value. Maintain it at stationary status. After 24 hours, measure the pressure drop. If it is not more than 0.05 MPa, it is qualified. 5.5.3 Test of elastic-properties 5.5.4 Volume test First use water to fill the air spring, to discharge the air from inside of the air spring. Then adjust the air spring to the maximum stretching status and ensure the water pressure is at 0.50 MPa. 5.5.6 Test of frame’s fatigue life Adjust the air spring to the standard height and 0.70 MPa air pressure. Disconnect the air source. It is recommended to use a single-swing arm which has an arm length of 600 mm or a symmetric two-way swing arm. The hinge point is located at ±30 mm on the air spring’s installation surface. At the frequency of 2.0 Hz ~ 3.0 Hz and the amplitude of ±50 mm, repeat vibrations. During the test, according to the actual test conditions, it may use the cooling method. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
