Description

Technical Field

[0001] The utility model belongs to the technical field of engineering machinery, and in particular relates to a wheel rim structure for a loader with an inner tube. Background Art

[0002] As a kind of earth-moving engineering machinery, loaders are currently widely used in many fields such as mining, transportation, municipal management and emergency rescue. Due to the complex, diverse and wide-span working conditions of its application, covering light, medium and heavy working intensities, the requirements for its supporting parts are also increasing simultaneously, not only to meet the most basic performance requirements, but also to ensure a certain degree of reliability. At present, among traditional fuel loaders, the 4-piece or 5-piece rim structure used by large-tonnage loaders has a complex structure and high manufacturing cost, while the three-piece rim structure used by medium-tonnage loaders consists of three parts: outer rim, lock ring and rim body, with simple structure and low cost.

[0003] For the three-piece rim, the existing structure is that the contact surface between the outer wheel flange and the lock ring is an arc surface, and the contact surface between the rim body and the tire bead is integrally molded, and the contact surface is smooth. However, electric loaders have the characteristics of fast response and large instantaneous torque. If the three-piece rim structure used by the existing traditional loader is adopted, under heavy load shoveling conditions, the tire is subjected to a large load when in contact with the ground, and the instantaneous torque of the motor is large, which will cause the tire and the rim to not roll synchronously, resulting in the tire rim being misaligned, causing tire rotation, thereby causing the tire bead to wear and the inner tube to wear. Summary of the invention

[0004] The utility model aims to overcome the deficiencies in the prior art and to provide a rim structure for a loader with an inner tube, which can effectively suppress the displacement of the tire and the rim body under high-load shoveling conditions of the loader, avoid abnormal noise when the tire is displaced and avoid damage to the tire bead due to wear of the contact portion between the tire bead and the rim body.

[0005] The utility model provides the following technical solutions:

[0006] A rim structure for a loader with an inner tube comprises a rim body, an outer wheel flange and a locking ring; the outer wheel flange is arranged on one side of the rim body, and the locking ring is arranged between the rim body and the outer wheel flange; the outer wheel flange and the locking ring are in planar contact; and a friction structure is arranged on the other side of the rim body.

[0007] As an optional technical solution of the present invention, the contact surface between the outer wheel rim and the locking ring is inclined, and the inclination angle is 44-46°.

[0008] As an optional technical solution of the present invention, the contact surface between the outer wheel rim and the rim body is a horizontal plane.

[0009] As an optional technical solution of the utility model, a tire is mounted above the rim body, and the friction structure is located between the rim body and the tire and is in contact with and connected to the tire.

[0010] As an optional technical solution of the present invention, the contact surface between the friction structure and the tire is inclined at 5°.

[0011] As an optional technical solution of the present invention, the contact surface between the outer wheel rim and the tire is inclined at 5°.

[0012] As an optional technical solution of the present utility model, the friction structure adopts a knurling structure.

[0013] As an optional technical solution of the present invention, the knurled structure is evenly arranged.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The rim structure for a loader with an inner tube provided by the utility model can effectively suppress the displacement of the tire and the rim body under high-load shoveling conditions of the loader by increasing the contact area between the outer wheel rim and the locking ring and increasing the friction between the tire bead and the rim body joint surface without changing the existing structure of the tire and without adding additional rim structural parts, thereby avoiding abnormal noise when the tire is displaced and damage to the bead due to wear of the contact portion between the tire bead and the rim body. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of a wheel rim structure for a loader with inner tube in an embodiment of the utility model.

[0017] Markings in the figure are: 101 - outer rim; 102 - locking ring; 103 - rim body; 104 - tire; 105 - friction structure. DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0019] Example 1

[0020] This embodiment provides a rim structure for a tube-type loader, such as Figure 1 As shown, it includes a rim body 103 , an outer wheel flange 101 and a locking ring 102 .

[0021] Specifically, the outer wheel rim 101 is disposed on one side of the rim body 103, and the locking ring 102 is disposed between the rim body 103 and the outer wheel rim 101. The outer wheel rim 101 and the locking ring 102 are in planar contact, which increases the contact area between the outer wheel rim 101 and the locking ring 102. A friction structure 105 is disposed on the other side of the rim body 103 to increase the friction between the rim body 103 and the tire 104.

[0022] Furthermore, a tire 104 is mounted above the rim body 103, and the friction structure 105 is located between the rim body 103 and the tire 104, and is in contact with and connected to the tire 104. The contact surface between the rim body 103 and the tire 104 is formed by integral compression molding.

[0023] Furthermore, the contact surface between the outer rim 101 and the tire 104 is inclined at 5°.

[0024] Furthermore, the contact surface between the outer rim 101 and the rim body 103 is a horizontal surface.

[0025] The rim structure provided in this embodiment is suitable for a three-piece rim assembly. Without changing the existing structure of the tire and without adding additional rim structural parts, it ensures a tighter fit between the tire 104 and the rim, and a more uniform contact surface at each part. This enables the structure to be suitable for traditional loading machinery conditions and also meet the conditions of instantaneous high torque of electric loaders, making it more widely and reliably applicable.

[0026] Example 2

[0027] This embodiment provides a specific implementation of the planar contact between the outer rim 101 and the locking ring 102 and the friction structure 105 based on the first embodiment.

[0028] The contact surface between the outer rim 101 and the locking ring 102 is inclined at an angle of 44-46°. In this embodiment, the contact surface between the outer rim 101 and the locking ring 102 is inclined at 45°, and the friction force is increased by increasing the contact area between the outer rim 101 and the locking ring 102.

[0029] In this embodiment, the contact surface between the friction structure 105 and the tire 104 is inclined at 5°. The friction structure 105 adopts a knurled structure, and the knurled structure is evenly arranged, so that the tire 104 and the rim body 103 are in uniform contact and force, thereby increasing the friction between the tire 104 and the rim body 101.
