METHOD FOR ROAD RELIABILITY TESTING OF VEHICLES

摘要

1. The method of road tests for the reliability of vehicles, which consists in moving vehicles along the j-th supporting surface in a leading transient driving mode, determined by the profile and bearing capacity of the supporting surface of standard test roads along their entire nomenclature, characterized in that the engine and transmission units forcefully loaded with alternating torque - positive from the engine in the half-cycle mode of acceleration in each gear and negative in the brake mode of the engine I (when turning off the fuel supply) and resistance to road traffic until the engine shaft speed decreases to a value corresponding to the maximum torque, followed by shifting to a higher gear using the clutch and then accelerating the engine in the previous gear mode until the highest gear and then into mode of the 2nd half-cycle by switching to lower gears at the same frequency in the mode of braking and stopping the car using standard brakes at a speed of 10 km / h, causing it most reliable by tribological fatigue strength and resistance, the acceleration, reducing the cost of the test run and the frequency shift is achieved rezhimov.2 variables. The method according to claim 1, characterized in that the mileage standards L in a special test mode are determined through the standard mileage on the A-road and G-road S during normal tests and the test acceleration coefficient K, which expresses the ratio of the number of times the clutch pedal is turned on (the process in which the gain or changing the sign of torque in a trance
