SAE J1505-2011 SAE J 1505-2011 标准

适用范围: "This SAE Recommended Practice provides the test procedure and instructions for air braked single unit trucks@ buses@ and combination vehicles. It also provides recommendations for: a. Instrumentation and equipment b. Vehicle preparation c. Calculating distribution of brake force Purpose This procedure provides a method to determine the brake force distribution and threshold pressures for trucks and buses with a GVWR greater than 4536 kg (10 000 lb). Other equipment and procedures could be used to determine approximate relative work or energy being absorbed by a vehicle's brakes. A ""performance based brake tester"" can determine low pressure/low speed torques of different brakes. A ""temperature/thermal balance"" can show relative temperatures of brakes@ thus indicating approximate energy absorbed."
