The linear clutch disc type self-adaptive automatic speed change electric drive axle comprises a first half shaft, a second half shaft and a differential mechanism which are coaxially arranged, a power motor and a speed change assembly are both installed on the first half shaft, and the speed change assembly comprises a frame clutch disc mechanism and an elastic mechanism which are both arranged on a shaft sleeve and are arranged in a linear mode; and the structure compactness is extremely high, and the device is suitable for application scenes with extremely strict requirements on installation space. And meanwhile, the expansibility of the structure is excellent, and the design requirements of platformization and modularization are met. Moreover, the motor can always work efficiently in the current high-efficiency area according to the change of the driving intention, a multi-parameter control strategy with the consciousness and intention of people as priority is realized, harmony and unification of people, vehicles, roads and running resistance/running load are realized, and the driving safety is improved. The important scientific and engineering technology common key problem of traction/driving force-running resistance/load efficient and accurate balance control is solved.

    本发明公开了一种一字型离合片式自适应自动变速电驱动桥,包括同轴设置的第一半轴、第二半轴和差速器,动力电机和变速总成均安装在第一半轴上,变速总成包括均设置在轴套上的框架离合片机构和弹性机构,呈一字型布置,结构紧凑度极高,适用于一些对安装空间要求极为严苛的应用场景。同时,结构的扩展性极佳,满足平台化和模块化的设计需求。并且,使电机能够根据驾驶意图的变化始终高效地保持在当前高效率区内工作,实现以人的意识和意图为优先的“多参数”控制策略,实现了人、车、路和行驶阻力/运行负荷的和谐统一,解决了牵引力/驱动力‑行驶阻力/载荷高效精确平衡控制的重大科学和工程技术共性关键难题。
