According to the multi-motor speed changing system, a single-intermediate-shaft structure of an original double-motor speed changer is changed into a double-intermediate-shaft structure, all idle gears and shafts do not need to be supported through needle bearings, meanwhile, due to the fact that power is shunted to the two same intermediate shafts, the center distance can be reduced, the tooth width is narrowed, the size of a speed changing box is more compact, occupied space is reduced, and the cost is reduced; the scheme that output shafts of the two motors are nested shafts and are arranged on the same side of the driving system is adopted to replace the scheme that the two sides of the two motors are symmetrically arranged in the prior art, the internal arrangement compactness of the driving system is further improved, the occupied space and size of the driving system are reduced, the weight is reduced, the load of the whole vehicle is reduced, vibration and noise are further reduced, the use safety is ensured and the service life is prolonged.

    本发明提供一种多电机变速系统,将原双电机变速器的单中间轴结构改为了双中间轴结构,所有的空套齿轮与轴之间不再需要通过滚针轴承支承,同时由于功率分流到两个相同的中间轴上,中心距可缩小,齿宽变窄,变速箱体积更紧凑,减少占用空间,降低成本;采用双电机输出轴采用嵌套轴且在驱动系统同侧布置的方案,以替换现有技术中双电机两侧对称布置的方案,进一步提高驱动系统内部布置紧凑度,减少驱动系统所占空间和体积,减少重量,降低整车的负重,进一步降低振动和噪音,保证使用安全,延长使用寿命。
