A structure for enabling independently suspended wheels to lean with vehicle hull, which comprises a linkage mechanism and two suspending mechanisms. The linkage mechanism comprises: a connecting part and a four-bar linkage structure composed of a ground rod, a floating rod, placed over the ground rod and parallel thereto, and two rocking arms; wherein an end of the floating rod is pivotally connected to an end of one rocking arm while another end of the floating rod is pivotally connected to an end of another rocking arm; and an end of the ground rod is pivotally connected to an end of one rocking arms opposite to that connected to the floating rod while another end of the ground rod is pivotally connected to an end of another rocking arm opposite to that connected to the floating rod; and the connecting part has a bulging sliding block matched and inset into a straight sliding slot arranged near center of the floating rod while the bottom of the connecting part is pivotally connected to a specific position of the ground rod near the center thereof. The suspending mechanism comprises: a hub, two suspending rods and a shock absorber; wherein the hub is pivotally connected to the rocking arm by the two suspending rods, and the top of the shock absorber is pivotally connected to the top of one rocking arm while the bottom of the shock absorber is pivotally connected to the bottom of the hub.
