The invention discloses a mounting structure and a mounting method for a hydrostatic gearbox drive axle assembly of engineering machinery, which avoid the mode of using a transmission shaft for transmission, realize small size and high space utilization rate of the assembly, and ensure the operation stability of the gearbox drive axle assembly through four-point connection between a frame and the gearbox drive axle assembly. According to the technical scheme, the gearbox drive axle assembly is divided into a speed reducer assembly and a gearbox assembly; cross beams on the two sides of the speed reducer assembly are provided with axle supporting seats respectively, the axle supporting seats are used for installing a frame to support the weight of the whole vehicle, and two-point connection is formed through the two axle supporting seats and the frame. The transmission assembly is arranged on the front side of the speed reducer, the speed reducer assembly and the transmission assembly are fixedly spliced through bolts, supports connected with a vehicle frame are arranged on the two sides of the top of the transmission assembly, and the gearbox drive axle assembly is in two-point connection with the vehicle frame through the two supports. And therefore, four-point connection is formed between the frame and the gearbox drive axle assembly.

    本发明公开了一种工程机械静液压变速箱驱动桥总成的安装结构与方法,避免了使用传动轴进行传动的方式,实现总成的体积小、空间利用率高,并通过车架与变速箱驱动桥总成之间的四点连接,保证了变速箱驱动桥总成运行稳定性,技术方案包括变速箱驱动桥总成,所述变速箱驱动桥总成分为减速器总成和变速箱总成;所述减速器总成两侧横梁分成设置有车桥支撑座,所述车桥支撑座用于安装车架支撑整车的重量,通过两个所述车桥支撑座与车架形成两点连接;所述变速器总成设置在减速器的前侧,所述减速器总成与变速器总成通过螺栓固定拼接,所述变速器总成顶部两侧设置有与车架相连的支架,所述变速箱驱动桥总成通过两个支架与车架形成两点连接,进而使车架与变速箱驱动桥总成之间形成四点连接。
