The invention discloses a crawler tractor transmission case which comprises a transmission case shell, a power input and output assembly is arranged at the front end of the transmission case shell, a sun wheel shaft is arranged at the tail end of the transmission case shell, and planetary gear trains are symmetrically arranged on the sun wheel shaft; the walking transmission assembly is arranged in the transmission case shell and used for adjusting the rotating speed of the sun wheel shaft, and an HST1 matched with the walking transmission assembly is arranged on the side wall of the transmission case shell; the steering assembly is arranged in the transmission case shell, and an HST2 matched with the steering assembly is arranged on the outer wall of the transmission case shell. Compared with a traditional crawler transmission system, the hydraulic transmission system has the beneficial effects that the hydraulic transmission system has the advantage of hydraulic and mechanical walking power switching, high efficiency of mechanical power and flexibility of hydraulic power are combined, the hydraulic planetary differential steering technology is integrated, and compared with a traditional steering clutch gearbox, no quick-wear part exists in the system; and the system has the advantages of long service life and high steering accuracy.

    发明公开了一种履带拖拉机传动箱,包括:传动箱壳体,所述传动箱壳体的前端设有动力输入及输出组件,所述壳体的尾端设有太阳轮轴,所述太阳轮轴上设有对称布置的行星轮系;行走传动组件,设置在传动箱壳体内,用于调节太阳轮轴的转速,所述传动箱壳体的侧壁上设有与该行走传动组件配合的HST1;转向组件,设置在传动箱壳体内,所述传动箱壳体的外壁上设有与该转向组件配合的HST2。有益效果在于:该发明与传统的履带传动系统相比,具备液压与机械行走动力切换的优势,使得机械动力的高效率与液压动力的灵活性相结合,集成了液压行星差速转向技术,较传统的转向离合器变速箱做到了系统内无易损件,系统使用寿命长,转向精准度高的优势。
