The utility model provides a shock absorption mechanism for a truck balanced suspension. The shock absorption mechanism for the truck balanced suspension comprises a shock absorber, an upper connecting board and a lower connecting board, wherein the upper connecting board and the lower connecting board are used for installation of the shock absorber. The upper connecting board is provided with installation holes I used for being connected with a frame and a stepped shaft connected with the upper end of the shock absorber, wherein the stepped shaft is perpendicular to the upper connecting board. The lower connecting board comprises a base board and a side board bent relative to the base board, installation holes II used for being connected with an axle are formed in the base board, and an installation hole III used for fixing the lower end of the shock absorber is formed in the side board. By the adoption of the scheme, the shock absorber is connected with the frame of a truck through the upper connecting board and connected with the axle of the truck through the lower connecting board, the shock absorber is arranged above the axle, the shock absorber is convenient to arrange, the damping effect of the shock absorber is improved in the mode that the installation angle of the shock absorber is changed, and the shock absorption mechanism is practical.
