The invention discloses an automobile transmission shaft supporting component, which is installed on a frame cross beam or an automobile body chassis and comprises a honeycomb rubber cushion block and a middle support. The honeycomb rubber cushion block is a disc-shaped rubber cushion block, a shaft hole is formed in the center of the disc face of the honeycomb rubber cushion block, evenly-distributed installation holes are evenly formed in the outer edge of the disc face, and the installation holes are perpendicular to the disc face. The middle support is located in the installation holes and comprises an elastic rubber sleeve and a bearing, the elastic rubber sleeve is a cylindrical barrel cavity, a fan-shaped connecting column is arranged in the cylindrical barrel cavity, the arc-shaped end faces of the two ends of the fan-shaped connecting column abut against the inner wall of the cylindrical barrel cavity and the bearing respectively, and the bearing is a cylindrical cavity. The bearing is eccentrically installed in the installation holes of the honeycomb rubber cushion block, the outer wall of the bearing and the small end of the fan-shaped connecting column are connected into a whole, and the radial position and the radial direction of the elastic rubber sleeve on the disc face are consistent. Through the elastic disturbance of the honeycomb rubber cushion bock and the middle bearing, the effect of compensating installation errors and displacement caused by engine movement and frame deformation in the running process can be achieved.
