Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, in particular to a double-rim wheel. Background Art

[0002] When a high-horsepower tractor or large engineering vehicle is under relatively heavy load conditions, the load-bearing wheel adopts a double-wheel structure, which can provide more tire support, greatly improve the vehicle's load-bearing capacity, extend the tire service life, and improve driving stability and controllability. At present, most double-wheel structure wheels are a combination of an inner wheel, an outer wheel, and a connecting flange. There are problems such as inconvenient removal of the outer wheel, difficulty in replacing the tire, and the inability to use the inner wheel alone after removing the outer wheel, which affects the use effect of the double-wheel wheel. For example, the patent with announcement number CN 206501647 U provides a double-rim wheel. When the outer wheel is removed, the flange is easily stuck. After the outer wheel is removed, the outer circle of the inner spokes still remains on the wheel, and the inner rim cannot be used alone, which affects the use effect of the double-rim wheel. Summary of the invention

[0003] The technical problem solved by the utility model is to provide a double-rim wheel. The wheel has the advantages that the outer wheel assembly is easy to disassemble and install, and the inner wheel assembly can be used alone after the outer wheel assembly is removed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A double rim wheel, comprising an inner wheel assembly and an outer wheel assembly, characterized in that: the inner wheel assembly comprises an inner rim and an inner wheel spoke bracket, the outer wheel assembly comprises an outer wheel rim, an outer wheel butt sleeve, and an outer wheel spoke bracket; the outer wheel rim is the same size and shape as the inner wheel rim; the inner wheel spoke bracket and the outer wheel spoke bracket are both annular brackets with L-shaped cross-sections, the outer diameter of the inner wheel spoke bracket is the same as the inner diameter of the inner wheel rim, and the inner wheel spoke bracket is welded to the inner wheel rim; the outer wheel butt sleeve is a sleeve with a larger outer end diameter , a stepped cylinder with a small inner end diameter; the outer circumferential diameter of the outer end of the outer wheel docking sleeve is the same as the inner diameter of the outer rim, the outer end of the outer wheel docking sleeve is inserted into the outer rim and welded to the outer rim, the outer circumferential diameter of the outer wheel spoke bracket is the same as the inner diameter of the inner end of the outer wheel docking sleeve, the inner end of the outer wheel docking sleeve is sleeved on the outer circumference of the outer wheel spoke bracket and welded to the outer wheel spoke bracket; the outer wheel spoke bracket and the inner wheel spoke bracket are connected by bolts, and there is a rim clearance between the outer circumference of the inner end of the outer wheel docking sleeve and the inner rim.

[0006] Furthermore, the thickness of the rim clearance is 4%-8% of the inner rim diameter.

[0007] The utility model has the following beneficial effects:

[0008] The utility model welds and connects the outer wheel rim, the outer wheel docking sleeve, and the outer wheel spoke bracket to form an integrated outer wheel assembly, which can be removed from the inner wheel assembly as a whole, and can easily realize the quick switching between single and double tires. After the outer wheel assembly is removed, the inner wheel assembly can be used alone without increasing the overall width of the vehicle. After the inner end diameter of the outer wheel docking sleeve is reduced in a step-like manner, a rim clearance is provided between the inner wheel rim, making the loading and unloading of the outer wheel assembly more convenient. The height of the rim clearance is limited to between 5% and 10% of the inner wheel rim diameter length, which can effectively ensure the structural strength of the outer wheel assembly without affecting the loading and unloading of the outer wheel assembly.

[0013] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The embodiment is only a part of the embodiments of the utility model, rather than all the embodiments.

[0014] Please refer to Figure 1-Figure 2 As shown, the utility model provides a double-rim wheel, including an inner wheel assembly and an outer wheel assembly, wherein the inner wheel assembly includes an inner rim 1 and an inner wheel spoke bracket 2, and the outer wheel assembly includes an outer wheel rim 3, an outer wheel docking sleeve 4, and an outer wheel spoke bracket 5; the outer wheel rim is the same size and shape as the inner wheel rim; the inner wheel spoke bracket 2 and the outer wheel spoke bracket 5 are both annular brackets with L-shaped cross-sections, the outer diameter of the inner wheel spoke bracket 2 is the same as the inner diameter of the inner wheel rim 1, and the inner wheel spoke bracket is welded to the inner wheel rim; the outer wheel docking sleeve 4 is the outer end diameter The outer wheel butt sleeve has a large outer diameter and a stepped cylindrical shape with a small inner diameter; the outer diameter of the outer end of the outer wheel butt sleeve is the same as the inner diameter of the outer rim; the outer end of the outer wheel butt sleeve 4 is inserted into the outer rim 3 and welded to the outer rim; the outer diameter of the outer wheel spoke bracket 5 is the same as the inner diameter of the inner end of the outer wheel butt sleeve 4; the inner end of the outer wheel butt sleeve 4 is sleeved on the outer periphery of the outer wheel spoke bracket 5 and welded to the outer wheel spoke bracket 5; the outer wheel spoke bracket 5 is connected to the inner wheel spoke bracket 2 by bolts; there is a rim clearance gap 6 between the inner periphery of the inner end of the outer wheel butt sleeve 4 and the inner rim 1. The thickness of the rim clearance gap 6 is 4%-8% of the inner rim diameter length.

[0015] During the specific implementation of the utility model, the inner wheel rim 1 is welded to the inner wheel spoke bracket 2 to form an inner wheel assembly. The outer wheel rim 3, the outer wheel docking sleeve 4, and the outer wheel spoke bracket 5 are welded to form an outer wheel assembly. The outer wheel spoke bracket 5 of the outer wheel assembly and the inner wheel spoke bracket 2 of the inner wheel assembly are connected by bolts to form a double wheel rim wheel. When the vehicle is used in a non-load-bearing state, the bolts between the outer wheel spoke bracket 5 and the inner wheel spoke bracket 2 are opened, and the outer wheel assembly can be removed from the inner wheel assembly as a whole. After the outer wheel assembly is removed, the inner wheel assembly can be used alone without increasing the overall width of the vehicle. After the inner end diameter of the outer wheel docking sleeve is stepped down, there is a rim clearance between the inner wheel rim, which makes the loading and unloading of the outer wheel assembly more convenient. The height of the rim clearance is limited to between 4% and 8% of the inner wheel rim diameter length, which can effectively ensure the structural strength of the outer wheel assembly without affecting the loading and unloading of the outer wheel assembly.
