大功率电驱轮边变速器的可靠性设计与试验开发

Reliability Design and Experimental Development for High-Power Electric Driving Wheel Gearbox

轮边变速器是多轴超重型混合动力试验平台的关键部件,由于应用场合的特殊性,一方面要求轮边变速器能够满足整车的动力性要求,同时又要满足轻质和高可靠性要求。因此,在轮边变速器的方案设计中,以轻量化为目标,以可靠性为约束条件,提出轮边变速器齿轮的优化设计方案。经高速试验、全载疲劳试验和过载疲劳试验验证,轮边变速器的性能与可靠性满足多轴超重型混合动力试验平台的使用要求。

The wheel gearbox is a key component of Multi-axis super-heavy hybrid test platform,for the special nature of the application,on the one hand to meet the requirements of vehicle wheel power transmission requirements,while also meet lightweight and high reliability requirements.Therefore,in the wheel gearbox design,taking the lightweight for the wheel gearbox as the target,reliability as constraints,the optimization design scheme of the wheel gearbox is proposed.After the high- speed test,full load fatigue test and overload fatigue test verification,the wheel gearbox performance and reliability meet the requirements of super- heavy hybrid multi- axis test platform.
