The invention discloses a power transmission speed change system assembly, which comprises an engine, a power transmission unit and a speed changer sequentially arranged in the shaft connection direction, wherein a flywheel assembly of the engine is arranged on the power transmission unit; and the engine and the flywheel assembly are in disconnected transmission connection through the power transmission shaft. By means of the technical scheme, disconnected transmission connection of the transmission and the engine is achieved, and meanwhile the separation function of the clutch is ensured notto be affected. Particularly, through the technical scheme, the problems that a transmission clutch shell of the mining wide-body dumper is broken, and time and labor are wasted when a clutch or an engine is disassembled and assembled are solved.

    本发明公开了一种动力传动变速系统总成,包括沿轴连动向依次设置的发动机、动力传动单元和变速器,所述发动机的飞轮总成设置在动力传动单元上;发动机与飞轮总成通过动力传动轴断开式传动连接。通过本发明的技术方案实现了变速器与发动机的断开式传动连接,同时保证离合器分离功能不受影响。特别的,通过本发明的技术方案解决矿用宽体自卸车变速器离合器壳体断裂以及拆装离合器或发动机费时费力的问题。
