a convenient spare tire tray comprises a tray main body and a through hole which is formed in the tray main body and used for allowing a lifting chain or a rope to pass through, wherein the tray main body is also provided with a positioning boss and a positioning column which are both arranged in an upward protruding mode, the positioning columns are symmetrically arranged on two sides of the positioning boss and correspondingly matched with positioning holes in a spare tire rim, and the peripheral hole diameter of the positioning boss is correspondingly arranged with the central hole diameter of the spare tire rim;
the outer edge of the positioning boss is of an arc-shaped structure, and the through hole is arranged in the center of the positioning boss and penetrates through the positioning boss.
The tray main body is of a long strip-shaped structure, and the positioning columns are correspondingly arranged on the extending parts on two sides of the long strip-shaped structure.
And the positioning column is also provided with a buffer gasket.
The thickness of the buffer gasket is 3-10 mm.
The buffer gasket is made of rubber.
The upper end face of the positioning boss is arranged in an inclined plane.
The utility model has the advantages that:
(1) this convenient type spare tyre tray, lay all the location boss and the reference column of upwards protruding equipment in the tray main part, main positioning action through the main location of location boss and the auxiliary positioning of reference column, guaranteed to load at whole spare tyre and rise or dismantle in descending, only need place spare tyre wheel hub central hole position with the spare tyre tray after, rotate capstan winch to spare tyre and automobile body chassis contact and tighten, or rotate capstan winch and take out the spare tyre tray from spare tyre wheel hub central hole position after contacting ground and can accomplish its operation, need not to carry out other operations again, the spare tyre has been promoted greatly and has been loaded, dismantle, fixed convenience.
(2) When the spare tire is loaded, the positioning column is exactly positioned at the position of the positioning hole on the spare tire rim, so that the mass center of the spare tire and the mass center of the spare tire tray assembly are on the same vertical line and are consistent with the steel wire rope, and the spare tire is ensured to be kept in a horizontal state in the ascending and descending processes; meanwhile, due to the structural design of the tray, the gravity center of the spare tire and the acting force of the steel wire rope are effectively ensured to be on the same vertical line, the movement of the spare tire in a fixed state is effectively inhibited, and the abrasion of the spare tire is reduced.
(3) The buffer spacer is made of rubber, so that the surface of the spare tire hub can be protected from being abraded, the spare tire is prevented from shaking in the running process of the vehicle, the vibration of the whole vehicle is reduced, and the NVH performance is improved.
