针对国产某新品载货汽车批量出现变速器齿轮怠速敲击异响问题,基于“猜想-理论研究-试验验证”的研究方法,分析并确认了变速器怠速敲击问题是由摩擦离合器一级扭转减振器参数与动力传动系统不匹配引起。对一级扭转刚度、干摩擦阻尼矩、正反向扭转角极限值与变速器齿轮敲击噪声的关系进行了研究,研究发现,通过调整离合器扭转减振器的扭转特性参数来解决变速器怠速异响问题是最简单且有效的方法。在保持一级正、反向扭转角极限值和干摩擦阻尼矩不变的前提下,优化了一级扭转刚度,制造了样件并装车测试,对离合器优化后采集的转速、噪声时域数据进行了后处理,并与离合器优化前的后处理数据进行对比分析,比较了主观感受。理论分析和测试均表明,调整一级扭转刚度后的摩擦离合器有效衰减了发动机输出的转速波动,变速器怠速敲击异响得到了有效抑制。该方法对解决其他同类变速器齿轮敲击问题具有参考价值。
Aiming at the problem of transmission gear idling knocking abnormal noise in a batch of domestically produced new trucks, based on the research method of "conjecture-theoretical research-test verification", the situation that the transmission idling knocking problem is caused by the friction clutch first-stage torsion damper and mismatch of parameters and power transmission system is analyzed and confirmed. The relationship between the first-stage torsional stiffness, dry friction damping torque, the limit value of the forward and reverse torsion angle and the transmission gear knocking noise is studied. The results show that, the torsion characteristic parameters of the clutch torsion damper can be adjusted to solve the abnormal noise of the transmission idling, which is the simplest and most effective method. Therefore, under the condition that the premise of keeping the first-class forward and reverse torsion angle limit values and dry friction damping torque unchanged, the first-class torsional stiffness is optimized, and the samples are manufactured and tested on the vehicle. The data of speed and noise time domain is collected after optimization of the clutch and is post-processed. Then compared with the before it had not been optimized, and the subjective feelings are compared. Both theoretical analysis and tests show that, the friction clutch after adjusting the first-stage torsional stiffness effectively attenuates the engine output speed fluctuations, and the transmission idling knocking abnormal noise is well suppressed. This method has reference value for solving other similar transmission gear knocking problems.
