The invention, which relates to the tractor head fixing device field, discloses a tractor head fixing chassis, thereby solving problems of insufficient rigidity, low stability and oil leakage caused by breakage of a transmission case assembly due to direct connection of a towing assembly and the transmission case assembly of a traditional tractor. The chassis comprises a head mounting base and a hub mounting frame. The head mounting base is connected with the hub mounting frame; a connecting seat and a steering seat which are connected with a trailer assembly are integrally arranged at one endof the hub mounting frame; a containing cavity capable of containing a transmission case assembly and a bottom frame of the transmission case assembly is formed in the middle of the hub mounting frame; a half shaft assembly for installing the hub assembly is arranged at the bottom of the hub mounting frame; and the transmission case assembly and the bottom frame are arranged in the containing cavity and connected with the half shaft assembly. According to invention, the width of the hub assembly can be increased, the reliability and stability of connection of the towing assembly are improved,side sway is reduced, and the problem that the transmission case assembly and the bottom frame are damaged is effectively solved.

    本发明公开了一种拖拉机的机头固定底盘,涉及拖拉机机头固定装置,解决传统拖拉机的拖挂总成与传动箱总成直接连接,导致刚性不足、稳定性不高传动箱总成断裂漏油的问题。该底盘包括机头安装座和轮毂安装架,所述的机头安装座与轮毂安装架连接,所述的轮毂安装架一端集成设置有与拖挂总成连接的连接座和转向座,所述的轮毂安装架中部开设有可容纳传动箱总成及其底架的容纳腔,所述的轮毂安装架底部设有用于安装轮毂总成的半轴总成,所述的传动箱总成及底架位于容纳腔内并与半轴总成连接。本发明的拖拉机机头固定底盘,可加宽轮毂总成的宽度,提高拖挂总成连接的可靠性和稳定性,减少侧摆,有效避免传动箱总成及底架损坏的问题。
