The invention discloses a wheeled auxiliary
obstacle crossing device which is composed of a housing, a blade wheel, a driving motor, support springs, a support rod
assembly and a sleeve; the blade wheel is located in the center of the cylindrical shell and is coaxially connected with the driving motor through a power shaft. The blade of the blade wheel, the support springs, the support rod
assembly and the sleeve are arranged in a set, and the sleeve is fixed on the inner side of the housing. In the support rod
assembly, one end of the support rod is fixedly connected with an arc plate on theouter side of the housing through the sleeve, the other end of the support rod vertically passes through the support plate and is pressed on the blade wheel through a roller at the end, and the support springs are arranged in pairs between the support plate and the housing; As the blade wheel rotate, the support rod moves along the arc surface of the blade through the roll wheel at the end. The invention enables the wheeled vehicle to run on the flat road in a simple and convenient manner, and can smoothly surmount obstacles under complex ground conditions, so that the wheeled vehicle has goodroad surface adaptability and passing capacity.
