Technological methods for noise/vibration reduction in driveline/transmission of trucks and all-wheel-drive vehicles 减少卡车和全轮驱动车传动系统噪音和振动的技术方法 Abstract: The paper is targeting solution to the problem of noise/vibration reduction in driveline/transmission of a truck and all-wheel-drive vehicle. It is customary to modify the gear micro-geometry to accommodate misalignment and minimize transmission error in a truck transmission. Various possible kinds of modification of a pinion tooth surface are considered. Topological modification of a pinion tooth surface, if a proper design is accomplished, yields up to two times reduction of transmission errors. Reduction of transmission errors results in corresponding reduction of noise/vibration excitation by a truck driveline/transmission. An advanced technology of finishing of topologically modified pinion tooth surface for low-noise/noiseless vehicle transmission is proposed. 摘要：本文旨在解决卡车和全轮驱动车传动系统噪音和振动过大的问题。通常可通过修改齿轮微观几何形状改善错位情况，最小化卡车的传动误差。有多种方法可用于修改小齿轮齿面。设计合理的情况下，应用拓扑修改可使传动误差减少两倍，从而相应减少卡车传动系统的噪音和振动。本文将讨论利用先进拓扑技术精修整小齿轮齿面以达到传动系统的低噪音或无噪音。 Keywords: truck; all-wheel drive vehicle; driveline; transmission; gear noise; vibration. 关键词：卡车；全轮驱动车；动力传动系统；传动装置；齿轮噪音；振动 Reference to this paper should be made as follows: Radzevich, S.P.
