摘　　要：随着汽车电动化的进程日益加快,电驱动城市物流商用车已成为了市场上一个重要车型。作为城市物流车的核心零部件,减速器的性能稳定变得至关重要。而减速器壳体在减速器运行中起到支撑保护功能,会受到多种重力负荷的作用。在面对电驱动状态下出现的复杂转速及扭矩工况时,往往会出现减速器壳体因应力集中受损、轴承因润滑不足烧蚀等多种问题。减速器壳体的结构设计直接影响到减速器总成的整体性能与可靠性。本文主要采用Masta、Particleworks软件,对电驱动商用车的减速器壳体进行有限元分析及结构优化设计。并搭载后桥总成进行台架试验验证。结果证明,所优化设计的减速器壳体符合相关汽车行业标准及实际应用需求。通过这一实用方法,提高了减速器壳体的强度、刚度及减速器总成轴承润滑能力。为电驱动商用车的高效、稳定运行提供了保障。也为后续电驱动后桥总成零部件开发及优化设计提供了思路。With the acceleration of the process of automobile electrification,electric drive urban logistics commercial vehicle has become an important model in the market.As the core parts of urban logistics vehicle,the performance stability of the reducer has become very important.The reducer shell plays a supporting and protecting function in the operation of the reducer,and will be affected by a variety of gravity loads.In the face of the complex torque conditions under the electric drive state,there are often a variety of problems such as the reducer shell damaged by stress concentration and the bearing ablation due to insufficient lubrication.The structural design of the reducer shell directly affects the overall performance and reliability of the reducer assembly.In this paper,the finite element analysis and structural optimization design of the reducer shell of the electric drive commercial vehicle are mainly carried out by using the software of Masta and Particleworks.And the rear axle assembly is carried out for bench test verification.The results show that the optimized design of the reducer shell meets the relevant automotive industry standards and practical application requirements.Through this practical method,the strength,stiffness and lubrication ability of the bearing of the reducer assembly are improved.It provides a guarantee for the efficient and stable operation of the electric drive commercial vehicle.It also provides a way for the subsequent development and optimization design of the electric drive rear axle assembly parts.
