Description
Technical Field
The invention relates to a matching structure of a check ring and a rim.
Background
The wheel with the inner tube is generally divided into a two-piece wheel and a three-piece wheel according to the structural form, the two-piece wheel comprises a spoke, a rim and a retainer ring, the three-piece wheel comprises the spoke, the rim, the retainer ring and a locking ring, the two-piece wheel has the advantages that the number of the locking rings is smaller than that of the three-piece wheel, the structure is simple, the assembly and disassembly are convenient, and a user prefers to use the two-piece wheel, but the retainer ring of the two-piece wheel has a tail structure 101, and the purpose of the tail structure 101 is to enable the toe of a tire to be pressed on the tail of the retainer ring when the tire is installed, so that the retainer ring is prevented from flying out in the use process, as shown in figure 1. However, due to the existence of the retainer ring tail structure 101, when the tire is pressed on the position again, the toe of the tire is damaged too early due to the stress, and even the toe of the tire is damaged and deflated in serious cases, so that the tire cannot be used.
As shown in fig. 2, since the width occupied by the three-piece wheel after the retainer ring 102 and the lock ring 103 are assembled is larger than the width occupied by the two-piece retainer ring, when the nominal width A1 of the three-piece wheel reaches the nominal width a of the two-piece wheel with the standard structure, the rim width needs to be lengthened by about 10mm; if the product mounting dimension offset distance H1 is ensured, the rim exceeds the spoke air holes, so that the combined outer welding seam 104 cannot be welded. If the composite outer welding seam 104 is ensured to be welded, the spokes need to be heightened, namely the offset distance H1 is increased, the total width K of the rear wheel is increased, and the installation can cause the edges to interfere with other parts of the automobile and cannot be used.
The retaining ring part of the wheel with the three-piece structure consists of the retaining ring and the locking ring, the weight of the two parts is increased by about 3kg than that of the single retaining ring, the width of the rim is increased on the premise of ensuring the width of the tire, the weight is increased, and finally the manufacturing cost is increased.
