电动车尾门电动推杆用低音调齿轮的开发与验证
Validation of Noise Reduction Using Low-Tone Gearing on a Push-Rod System
摘要
Abstract
Electric motors with very high speeds are used widely for highly automated and autonomous driving. A low weight design of high-speed electric motors can reduce the demand for environmentally harmful materials. However,due to the regular involute gears,which are usually used with high-speed motors to bring the rotation speed and output torque into target values,a noticeable and extremely annoying tonal noise occurs, which compromises the comfort of passengers significantly. Thus,an innovative low-tone gearing with irregular design of tooth is introduced to reduce the noise of gear transmissions. To obtain a low-tone gearing design for an electric push-rod system,which operates the tailgate of vehicles to either open or close, an optimization is conducted. Then for comparison,the sound pressure of the low-tone gearings and a regular design is measured during the operation of the push-rod system. Finally,the reduction of noise by using the low-tone gearing, especially from the aspect of the tonality,is validated by analyzing the measured data.关键词
