The invention relates to a double-clutch multi-gear transmission case which comprises a forward and backward power reversing assembly, a multi-gear assembly, a high-low gear shifting device, a front axle output assembly, a rear axle output assembly and a PTO power output assembly, and a forward and backward power input assembly comprises a shaft I, a shaft II, a shaft III, a shaft IV, a shaft V, a reverse clutch and a forward clutch. The multi-gear assembly comprises a shaft VI, a shaft VII and synchronizers, the three sets of synchronizers are arranged on the shaft VI, connection and arrangement of the three sets of synchronizers are controlled through a gear shifting handle, so that switching of six gears is achieved, and the rear axle output assembly comprises a central transmission, a differential mechanism, a brake and a final transmission. Organic switching of a plurality of forward gears and a plurality of reverse gears is achieved, electric hydraulic control is adopted, front and back power reversing is achieved, power combination and separation of PTO power output are achieved, the structure is compact, disassembly and assembly are convenient, work is reliable, and imported products can be replaced.

    本发明涉及双离合多档位传动箱,包括前进后退动力换向组件、多档位组件、高低档换挡装置、前桥输出组件、后桥输出组件和PTO动力输出组件,所述前进后退动力输入组件包括Ⅰ轴、Ⅱ轴、Ⅲ轴、Ⅳ轴、Ⅴ轴、倒车离合器和前进离合器,所述多档位组件包括Ⅵ轴、Ⅶ轴和同步器,三组同步器设置在Ⅵ轴上,通过换档手柄控制三套同步器的接排,使得实现6个档位的切换,所述后桥输出组件包括中央传动、差速器、制动器和终传动,本发明实现了多个前进档位、多个倒退档的有机切换,采用电液控制,实现前后动力换向,实现PTO动力输出的动力结合和脱开,结构紧凑,拆装方便、工作可靠、可以替代进口产品。
