摘　　要：某多轴超重型底盘由于高机动性和高越野性要求,对使用的大功率分动器提出了轻量化、大功率和高可靠性的设计要求,其中主传动斜齿圆柱齿轮作为重型车辆分动器的核心部件,其设计不但包括主传动方案、齿轮模数、齿数、齿宽等主传动参数,还包括变位系数和齿顶高系数等原件参数,以往经验式的设计方法不但周期长,而且不同参数变量之间关系复杂,很难全面反映组成结构的各细节要求。本文采取双级优化设计方法,对重型车辆分动器主齿轮进行了优化设计。由于多轴超重型底盘可靠性要求高,本文综合了汽车行业分动器试验规范和整车实际应用环境,提出了适用于多轴超重型底盘分动器的疲劳试验考核方法,并对原有分动器和新分动器的结构强度计算与疲劳试验结果进行了对比,证明优化方案能够满足多轴超重型底盘分动器设计要求。A multi-axis super-heavy chassis for the high mobility and high wild requirements,so the high power transfer case need to meet the requirements for lightweight,high-power and high-reliability design,wherein the main drive helical gear as the core component for a heavy vehicles transfer case,which is designed to include not only the main transmission scheme,gear module,number of teeth,tooth width and other main transmission parameters,but also include the original level parameter modification coefficient and the addendum coefficient,the conventional empirical design method is not only need a long period of time,but also the relationship between different parameters and variables enormous complexity,which is difficult to get all the details of the structure of the composition of claim fully reflected.This paper took the two-stage design optimization method,the main heavy vehicles transfer case gear has been optimized.While,due to the high reliability of the multi-axle super-heavy chassis,this paper combines the test rules of the automotive transfer case and the practical application environment of the vehicle,putting forward the reliability test method for the high power transfer case.In the end,the structural strength and the reliability of the test results were compared between the former and the new transfer case,proved that the optimization program of the transfer cases could meet the multi-axis super-heavy chassis lightweight,high-power and high-reliability design requirements.
