Problems solved by technology
a kind of in figure 1 On the basis of the axle, the improved form of refitting the double rim into a single rim, such as figure 2 As shown, the rim is made to be long, but after the modification, it is found that when the gland is pressed inward, the inner ring of the rim and the axle shoulder of the axle are prone to slippage, which causes the axle shoulder of the axle to crack under pressure, such as figure 2 A marked in the middle, therefore, obviously this kind of rim form is not advisable, this problem needs to be solved

Embodiment Construction
[0027] The present invention will be described in detail below with reference to the accompanying drawings and embodiments, which are used to explain the embodiments. But those skilled in the art should know that the following examples are not the only limitation to the technical solution of the present invention, and any equivalent transformation or modification made under the spirit of the technical solution of the present invention should be regarded as belonging to the protection of the present invention scope.
[0028] like image 3 As shown, according to the common rim form of trucks, the present invention selects a flat-bottomed rim, including a rim body 1, an elastic locking ring 2, a seat ring 3, a retaining ring 4, and a thrust ring 5. The key of the present invention is to ensure that the rim is When the body 1 is long enough, the rim body 1 will not cause overpressure on the axle shoulder of the axle through the blocking effect of a thrust ring 5 embedded therein....

The invention discloses a novel rim, which is suitable for mounting a widened single tire on a large vehicle, and comprises a rim body, an elastic locking ring, a seat ring, a check ring and a thrust ring. An annular groove is formed in the inner surface of the outer end of the rim body, and the thrust ring is installed in the annular groove in a matched mode. The longitudinal sections of the annular groove and the thrust ring are trapezoidal, and the inner base angles of the trapezoids are the same as the inclination of the axle shoulder; a shaft shoulder face matched with an axle shaft shoulder is machined on the inner surface of the inner end of the rim body, and the inclination of the shaft shoulder face is the same as that of the axle shaft shoulder. An anti-rotation key is further arranged on the inner surface of the rim body, and the anti-rotation key is installed in a valve passing groove of an axle in a matched mode. By improving the rim body, only one widened single tire can be installed on a lengthened axle, the thrust ring can relieve inward thrust borne by the rim, pressure on the axle is reduced, and the axle is prevented from being damaged.
Description
technical field [0001] The present invention relates to a wheel rim, in particular to a single-tire rim structure retrofitted on an axle suitable for mounting double tires. Background technique [0002] A wheel consists of a hub, a rim, and spokes connected between these two elements. The rim is the part that installs the tire on the outermost ring of the wheel, commonly known as the rim, and the rim is tightly clamped on the outer edge of the axle. For large trucks, the main load capacity is at the rear, and the load of the rear axle is much larger than that of the front axle. In order to meet the bearing capacity and driving stability, so that the rear tires will not be overloaded, the rear axle is generally equipped with double-type tires. The rim form is as follows figure 1 As shown in the figure, since the part where the tire is mounted on the axle is relatively long, two rims 1-1 and 1-2 are installed on the axle, and the two rims are supported and separated by the sl...
