Abstract

The utility model discloses an installation structure of a truck tail beam. The installation structure of the truck tail beam comprises a tail beam, two connecting frames and frame longitudinal beams, wherein the frame longitudinal beams are arranged on two sides of a truck body. Two ends of the tail beam are connected with inner lateral sides of the frame longitudinal beams on two sides of the truck body through the two connecting frames. Each connecting frame is composed of two wing plates and a connecting plate. Each two wing plates are arranged on two ends of the connecting plate in a mutually parallel mode. The wing plates and the connecting plates are in an integral structure. The cross section of each wing plate is in a trapezoid shape. The width of the lower bottom of each trapezoid shape is larger than the width of the upper bottom of each trapezoid shape. The width of the upper bottom of each trapezoid shape is larger than or equal to the width of the tail beam. The width of the lower bottom of each trapezoid shape is smaller than or equal to the width of each connecting plate. The lower bottom end of each trapezoid shape is connected with each connecting plate. The end portion of the tail beam is arranged at the position, within the range of the width of the upper bottom of each trapezoid shape, between the inner lateral sides of the two wing plates. The inner lateral sides of the wing plates are fixedly connected with the upper lateral side and the lower lateral side of the end portion of the tail beam. The outer lateral sides of the connecting plates are connected with the inner lateral sides of the longitudinal beams. The installation structure of the truck tail beam has the advantages of being capable of enabling acting force of the tail beam to be dispersed to a larger area and improving stability of the structure of a truck frame.
