Technical Problem
[0004]针对上述的缺陷或不足，本实用新型提供了一种双电机传动系统及农用机械，旨在解决因现有的双电机传动装置设有若干行星齿轮机构而导致结构复杂和生产难度大的技术问题
Benefits of technology
当使用上述的双电机传动系统时，由于包括车桥驱动轴、第一电机轴、第二电机轴、作业传动轴和中间转接轴，作业传动轴通过第一离合装置与第一电机轴连接，中间转接轴与第一电机轴之间设有啮合传动的第一齿轮组，中间转接轴或第一电机轴上设有第一接合装置，以与第一齿轮组接合或断开，中间转接轴与第二电机轴之间设有啮合传动的第二齿轮组，中间转接轴与车桥驱动轴之间设有挡位切换装置，则通过控制第一接合装置和第一离合装置可使得第一电机的动力传递至作业传动轴和中间转接轴中的至少一者，以实现第一电机的动力路径的选择切换，第二电机的动力可通过第二齿轮组传递至中间转接轴，则使得中间转接轴还可接受来自第二电机的动力，并且第一电机和第二电机的动力可在中间转接轴上进行耦合，由此使得挡位切换装置在进行动力传递时，车桥装置存在单电机驱动和双电机耦合驱动两种控制方式，此外，挡位切换装置的增设使得还可实现挡位切换，相较于现有技术中采用若干行星齿轮机构，明显可起到简化结构、降低生产难度以及提高可靠性的作用。
