The invention discloses a mounting structure of a drum brake assembly and an axle assembly. The mounting structure of the drum brake assembly comprises an axle, a main beam and the brake assembly. The axle extends along the transverse direction of the main beam and is fixedly connected with the main beam; the main beam comprises two side walls, a top wall and a bottom wall, and the two side walls, the top wall and the bottom wall jointly define a containing cavity; the braking assembly comprises a braking bottom plate, a cam shaft, an adjusting arm and a braking air chamber, the extending direction of the cam shaft is consistent with that of the axle, the inner side end of the cam shaft penetrates through the side wall, close to the outer side, of the main beam and extends into the containing cavity, one end of the adjusting arm is connected to the inner side end of the cam shaft, and the other end of the adjusting arm penetrates out of the bottom wall of the main beam to the position below the main beam; the brake chamber is installed on the main beam, and a push rod of the brake chamber is connected to the other end of the adjusting arm and used for driving the adjusting arm to swing. Layout of other parts of a vehicle is facilitated, meanwhile, the length of the cam shaft is shortened, and the assembly precision of the cam shaft is improved.

    本发明公开了一种鼓式制动组件的安装结构及车桥总成,鼓式制动组件的安装结构包括车轴、主梁、制动组件;车轴沿主梁的横向延伸并与主梁固定连接;主梁包括两个侧壁、顶壁、底壁,两侧壁、顶壁以及底壁共同围成一容纳腔;制动组件包括制动底板、凸轮轴、调整臂、制动气室,凸轮轴的延伸方向与车轴的延伸方向一致,其内侧端穿过主梁靠外侧的侧壁并延伸至容纳腔中,调整臂的一端连接于凸轮轴的内侧端,调整臂的另一端由主梁的底壁穿出至主梁的下方,制动气室安装在主梁上,制动气室的推杆连接在调整臂的另一端并用于带动调整臂摆动。本发明有利于车辆其他部件的布局,同时缩短的凸轮轴的长度,提高了凸轮轴的装配精度。
