When the sidecar three-wheeled motorcycle passes through an uneven road surface, the sidecar 1 drives the fixing seat 5 at the bottom to produce a vertical displacement, and the fixing seat 5 drives the cradle 4 to rotate along the front end of the bracket 2. The cradle 4 and the rocker arm 7 are hinged through the connecting rod 6 to realize that when the cradle 4 rotates around the front end of the bracket 2, the support arm 701 on the rocker arm 7 is driven to move along the middle of the bracket 2. Rotation, at the same time, one end of the rocker arm 7 drives the shock absorber 8 to axially extend and retract and rotate along the rear end of the bracket 2 through the hinge with the shock absorber 8. The shock absorber 8 can absorb the axial force applied by the rocker arm 7 to the shock absorber 8 during the axial extension and retraction process. The device forms a rocker frame 4 combination through the rocker frame 4 on the front side of the bottom of the bracket 2 and the rocker arm 7 on the rear side. The vertical displacement of the side bucket 1 and the front and rear displacement generated in the horizontal direction are suppressed through the rocker frame 4 combination and the shock absorber 8, thereby improving the shock absorption effect of the side bucket 1 and improving the comfort of the occupants.
