Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a caba wheel single tire wheel and a wheel hub thereof. Background Art

[0002] Cars have become one of the most commonly used means of transportation. Car wheels are the main components for installing tires and supporting the driving of cars. Their strength and structure play a vital role in the operation of vehicles. Due to the heavy load of cabs, the rear wheel assembly is double-installed with two hubs to play a bearing role. The cost of the double hub assembly is high, and the user cost is also high. Therefore, it is necessary to develop a heavy-duty single-tire hub that can meet the heavy-duty needs and save production costs. Utility Model Content

[0003] The utility model aims to provide a kaba wheel single tire wheel and a wheel hub thereof, so as to solve the problems of high use cost, difficulty in loading and the like existing in the prior art.

[0004] On the one hand, the technical solution provided by the utility model is as follows:

[0005] A kaba wheel single tire hub comprises a spoke and a rim, wherein the spoke is located on the inner side of the rim, and a protrusion is arranged at a position on the rim connected with the tire.

[0006] Preferably, the protrusion is sawtooth-shaped.

[0007] Preferably, the protrusions are distributed in an annular shape along the circumferential direction of the rim.

[0008] Preferably, the spokes are located at a load-bearing front point offset from the center dimension of the rim.

[0009] On the other hand, the technical solution provided by the utility model is as follows:

[0010] A Kaba wheel single-tire wheel comprises a wheel hub and a tire, wherein the tire is arranged around the wheel hub, wherein the wheel hub is any of the above-mentioned Kaba wheel single-tire wheel hubs.

[0011] Analysis shows that the utility model can evenly disperse the force-bearing area, the rim is not easily deformed, the service life of the wheel hub is increased, and the single-tire design can reduce the user's cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic diagram of the main structure of an embodiment of the utility model;

[0013] Figure 2 It is a cross-sectional structural schematic diagram of an embodiment of the utility model (the tire is not fully shown);

[0014] Figure 3 for Figure 2 Schematic diagram of the partially enlarged structure. DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] like Figure 1-Figure 2 As shown, the wheel embodiment of the utility model comprises a tire 1 and a wheel hub, wherein the tire 1 is arranged around the outer circumference of the wheel hub.

[0017] For example Figure 2 , Figure 3 As shown, the wheel hub includes a rim 8, a spoke 7, and a central connecting disk 4. The central connecting disk 4 is concentrically arranged in the inner area of ​​the rim 8, and the spoke 7 is a continuous annular structure and connects the central connecting disk 4 and the rim 8. The rim 8 is provided with a valve hole 6.

[0018] On the central connecting plate 4, a shaft head hole 3 for connecting with the vehicle shaft is provided at its center, and bolt holes 5 for connecting with the tire brake drum are evenly arranged along the circumferential direction on the outer ring of the shaft head hole 3.

[0019] In order to achieve the purpose of the utility model, the rim 8 is provided with a curved limiting boss 2 at the connection with the tire 1, and the limiting boss 2 includes two parts: an inner ring 21 on the inner side and an outer ring 22 on the outer side, and the outer ring 22 is more curved in the direction of the tire 1 than the inner ring 21, so as to achieve the preliminary positioning of the tire 1. Furthermore, a protrusion 800 is provided at the position where the limiting boss 2 is connected with the tire 1, and the protrusion 800 is distributed in an annular manner along the circumferential direction of the rim 8. More preferably, the protrusion 800 is sawtooth-shaped.

[0020] In addition, the spoke 7 is located at the front point of the load offset from the center of the rim 8, and the symmetrical center design makes the left and right rims 8 evenly stressed, making the rim 8 less likely to deform, more impact resistant, more load-bearing, and longer service life. The tread serration design of the rim 8 increases the friction between the tire 1 and the rim 8 so that it cannot rotate, and the limiting boss 2 prevents left and right movement, preventing the tire 1 from falling out when rotating at high speed, and having good safety.

[0021] Through the above improvements, the utility model not only provides a high-strength Kaba wheel single tire hub that can meet the heavy-load force requirements, but also changes the original 22.5*9.0 rear wheel double-assembly product into a 22.5*16 single-assembly product without affecting the assembly parameters of the whole vehicle, and the performance in many aspects such as use cost and load bearing can be improved.

[0022] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
