The invention relates to the technical field of independent suspensions of cross-country vehicles, and particularly discloses a hub motor large-stroke suspension and vehicle body connecting structure which comprises an upper limiting device, an elastic damping element, a lower limiting device, an upper cross arm assembly and a lower cross arm assembly. One end of the upper cross arm assembly and one end of the lower cross arm assembly are hinged to a steering knuckle of the hub motor through a spherical hinge assembly, and the other end of the upper cross arm assembly and the other end of the lower cross arm assembly are connected with a vehicle body through knuckle bearings; the upper limiting device is installed on the outer side of the vehicle body and above the upper cross arm assembly, the lower limiting device is installed on the outer side of the vehicle body and below the upper cross arm assembly, the top of the elastic damping element is installed on the vehicle body, and the bottom of the elastic damping element is installed on the lower cross arm assembly; the suspension stroke is greatly increased and the riding comfort is improved by optimizing suspension hard point coordinates and matching a proper guide mechanism and a vehicle body structure, the structures of the front suspension and the rear suspension are the same, the generalization rate of the suspension system is increased, the development period is shortened, and the cost is effectively reduced.

    本发明涉及越野汽车独立悬架技术领域,具体公开了一种轮毂电机大行程悬架及车身连接结构,包括上限位装置、弹性阻尼元件、下限位装置、上横臂总成和下横臂总成,上横臂总成和下横臂总成的一端均通过球铰链总成与轮毂电机的转向节铰接,上横臂总成和下横臂总成的另一端均通过关节轴承与车身连接;上限位装置安装在车身外侧且在上横臂总成的上方,下限位装置安装在车身外侧且在上横臂总成的下方,弹性阻尼元件的顶部安装在车身上,弹性阻尼元件的底部安装在下横臂总成上;本发明通过优化悬架硬点坐标,匹配合适的导向机构和车身结构,大幅增加悬架行程,提升乘坐舒适性,前后悬架结构相同,提高了悬架系统的通用化率,减少开发周期,有效降低成本。
