Research And Development Of Integrated Test Rig Of Automobile Drive-axle Assembly

Abstract Content::Along with the progress in science and technology and automobile plant of auto parts to improve quality control, especially for the drive axle of quality control, auto-driven power train bridge in the end, is the main vehicle assembly and for the whole of it The power train, traveling and braking system, such as the Department of a key, but also affect many aspects of vehicle performance. Bridge drive under heavy loads and complex, it is necessary to transfer power train of the largest torque; bear on the role of the road or inside the frame and between the vertical, horizontal and vertical static and dynamic (impact) load, as well as counter-productive moment Torque and braking, and so on. The role of these loads, in the form of damage to the drive axle is also a wide range.At present, many auto factories on the drive axle detection, mostly to a particular individual for the purpose of the trial, a special test, so an urgent need to be able to detect the on-line drive axle assembly of a comprehensive performance test-bed.Bridge assembly of integrated performance-driven detection units to be completed drive axle assembly-line performance testing, as is the drive axle gear of the main transmission components, gears in the transmission process can not be ignored is the noise factor, the A5661 through the sound-pulse precision Terms of its level test in order to ensure its allowed limit. Torque a direct reflection of the drive axle of the ability to drive, drive axle detection is essential to test one of the indicators, through intelligent JCZ-speed torque sensors to achieve accurate measurement of torque. Oil gear transmission gear is essential to protection measures, it has a good seal on the drive to become the basic functions of the bridge, we must ensure that no oil spill, the use of pressure sealing of the detection method. As the drive axle bad working condition, the bearing temperature is also a more important indicator of the use of infrared thermometer MT4 bearing temperature detection to determine the pre-bearing situation. Differential lock is an important component of the drive axle components, their functions are in working directly determines the state of motor vehicles traveling through the differential function testing agency to determine whether or not the normal differential. Braking function is to compare closely with the security performance, braking, through testing can determine the braking function.This article first from the theoretical point of view, the combination of domestic and foreign realities, focusing on analysis of the drive axle vehicle performance on-line detection of the need for the development of Taiwan, followed by the key issue from the start, determine a reasonable design, the final adoption of the strict implementation of the completion of the testing station The development, testing and Taiwan to improve the car drive axle plant factory passing rate, product quality analysis has important practical significance.
