Abstract
The utility model discloses a tubeless wheel rim which comprises a tyre bead seat; a first retainer ring is arranged on one side of the tyre bead seat, a locked groove ring is fixedly connected on the other side of the tyre bead seat, a second retainer ring is sleeved on the periphery of the locked groove ring, a locking collar for preventing the second retainer ring from moving towards the outer side is arranged between the locked groove ring and the second retainer ring, a first obturating ring is arranged between the second retainer ring and the locked groove ring; the first obturating ring eliminates the movement gap between the locked groove ring and the second stop collar, the air tightness of an inflating cavity is improved, and the use is more durable.
Description
Technical field
The utility model relates to a kind of wheel rim technical field, relates in particular to a kind of inner tube free wheel rim.
Background technology
The wheel of C-class and passenger vehicle is extensive use of inner tube-free wheel.The structure of wheel rim generally is divided into two classes, one class is an integral type, one class is split type, the structure of known split type wheel rim is: the both sides of bead seat are respectively equipped with a back-up ring, one of them back-up ring and bead seat are made as one, another back-up ring and bead seat flexibly connect, and bead seat bottom surface and tyre bead inside face form the sealing inflating cells of ring-type, directly to the tubeless wheel of this chamber inflation just formation.The advantage of this split type wheel rim is to be convenient to fitting of tire, but has the gap between movable back-up ring and the bead seat, gas leakage easily, and leak tightness is poor, has potential safety hazard.
The utility model content
Technical problem to be solved in the utility model provides a kind of inner tube free wheel rim, and this wheel rim not only is convenient to mounting of tyre, and better tightness.
For solving the problems of the technologies described above, the technical solution of the utility model is: the inner tube free wheel rim, comprise bead seat, one side of described bead seat is provided with first back-up ring, the opposite side of described bead seat is fixedly connected with gutter ring, the periphery of described gutter ring is arranged with second back-up ring, is used to limit the mobile laterally retainer of described second back-up ring and is arranged between described gutter ring and described second back-up ring, is provided with first seal ring between described second back-up ring and the described gutter ring.
As a kind of improvement, the surface that described first back-up ring contacts with tyre bead is provided with second seal ring, and the surface that described second back-up ring contacts with tyre bead is provided with the 3rd seal ring.
Owing to adopted technique scheme, the inner tube free wheel rim, comprise bead seat, one side of described bead seat is provided with first back-up ring, the opposite side of described bead seat is fixedly connected with gutter ring, the periphery of described gutter ring is arranged with second back-up ring, is used to limit the mobile laterally retainer of described second back-up ring and is arranged between described gutter ring and described second back-up ring, is provided with first seal ring between described second back-up ring and the described gutter ring; First seal ring has been eliminated the free gap between the gutter ring and second back-up ring, has improved the leak tightness of inflating cells, and it is more permanent to use.
Because the surface that described first back-up ring contacts with tyre bead is provided with second seal ring, the surface that described second back-up ring contacts with tyre bead is provided with the 3rd seal ring again.The setting of second seal ring and the 3rd seal ring makes inflating cells still can keep good sealing property under the situation that air pressure reduces slightly.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, the inner tube free wheel rim, comprise bead seat 1, one side of described bead seat 1 is provided with first back-up ring 2, the opposite side of described bead seat 1 is fixedly connected with gutter ring 3, the periphery of described gutter ring 3 is arranged with second back-up ring 4, is used to limit the mobile laterally retainer 5 of second back-up ring 4 and is arranged between described gutter ring 3 and described second back-up ring 4, is provided with first seal ring 8 between described second back-up ring 4 and the described gutter ring 3.The setting that described second back-up ring 4 and gutter ring 3 are split type leak tightness between them is reduced greatly, and the setting of first seal ring 8 has solved the problem of leaking gas between second back-up ring 4 and the gutter ring 3, has improved the leak tightness of whole tire.
The surface that described first back-up ring 2 contacts with tyre bead is provided with second seal ring 6, and the surface that described second back-up ring 4 contacts with tyre bead is provided with the 3rd seal ring 7.Because the elastic ratio of second seal ring 6 and the 3rd seal ring 7 is bigger, can make inflating cells under the situation that air pressure reduces slightly, still can keep good sealing property.
Above-mentioned seal ring preferentially adopts rubber seal.
