Description

TECHNICAL FIELD

[0001] The application relates to a rim structure for a vacuum tire. BACKGROUND

[0002] The rim is a component for mounting and supporting the tire, and is crucial for maintaining the stability of the tire. Since the load of the mining vehicle is large, a rim with a steel plate roll-welding structure is generally used.

[0003] The steel plate roll-welding structure has high requirements for the welding process, has multiple welds, and has high deformation, open welding and air leakage damage rates in use, and also accelerates the wear of the tire; compared with the steel plate roll-welding structure, the cast rim has slightly higher cost, good shock absorption, prolonged service life of the tire, improved overall processing sealing performance, greatly reduced damage rate and improved vehicle attendance rate.

The application completes the clamping of the vacuum tire through the cooperation of the fixed flange and the adjustable flange. When the adjustable flange is fixed, the locking ring is clamped into the clamping groove below the integrated adjustable flange, which has good structural stability and is easy to assemble during use.

[0005] Preferably, the locking ring comprises a clamping block inserted into the clamping groove, an oblique block is arranged on the clamping block, and an oblique positioning surface is arranged at the position of the oblique block relative to the adjustable flange; an oblique abutment surface is arranged at the position of the adjustable flange corresponding to the oblique block.

[0006] Preferably, the adjustable flange comprises an abutment plate in abutment with the rim body, a vertical flange is arranged on the side of the abutment plate away from the fixed flange, a horizontal plate is arranged on the side of the vertical flange away from the fixed flange, and the abutment plate and the vertical flange are obliquely arranged near the side of the rim body to form an oblique positioning surface. The application is provided with an oblique abutment surface and an oblique positioning surface, which can play a guiding and positioning role when abutting, so that the clamping block can stably slide into the clamping groove, and then the structure clamping is completed, thereby ensuring the assemblability of the structure.

[0007] Preferably, an auxiliary groove is further arranged on the side of the clamping groove close to the rim body.

[0008] Preferably, a transition groove is arranged at the position corresponding to the abutting plate of the auxiliary groove, and the transition groove is arranged at the upper portion of the auxiliary groove towards the end of the fixed baffle; and the end of the transition groove away from the fixed baffle is connected to the smooth transition of the inclined positioning surface.

[0009] Preferably, the abutting plate is provided with a ring-shaped groove on the side towards the rim body, and a ring-shaped sealing ring is arranged in the ring-shaped groove.

Through the matched arrangement of the first clamping angle and the second clamping angle, the positioning clamping groove can be clamped into the first clamping angle, without structural deformation, and the stability after assembly is good. When it is necessary to take out, the second clamping angle is an obtuse angle, so it can be easily slid out. Through the design of the transition groove, a lever structure is formed with the transition groove as the fulcrum and the distal end of the abutting plate as the contact point, and the structural stability and sealing strength are more effectively guaranteed.

[0011] Preferably, an outer protective plate is arranged on the rim body on the side of the adjustable baffle, a plurality of bolt connection holes are arranged on the outer protective plate, an inclined connecting plate is arranged between the outer protective plate and the rim body, and a plurality of ventilation holes are arranged on the inclined connecting plate.

[0012] Preferably, the adjustable baffle is integrally arranged.

[0013] Preferably, an air valve passage is arranged on the hub body, and an air valve concave sealing ring is arranged on the outer side of the air valve passage.

[0014] The application can bring the following beneficial effects:

[0015] 1. The application completes the clamping of the vacuum tire through the cooperation of the fixed baffle and the adjustable baffle. When the adjustable baffle is fixed, a locking ring is clamped into the clamping groove below the integrally arranged adjustable baffle, so that the structural stability is good and the assembly is easy during use.

[0016] 2. The application is provided with the inclined abutting surface and the inclined positioning surface, which can play a guiding and positioning role when abutting, so that the clamping block can be stably slid into the clamping groove, and then the structural clamping is completed, thereby ensuring the assembly of the structure.

[0017] 3. The first and second clamping angles cooperate to ensure that the positioning clamping groove is clamped into the first clamping angle without structural deformation, and the stability after assembly is good. When it is necessary to remove, the second clamping angle is an obtuse angle, so it can be easily slid out. The transition groove forms a lever structure with the present location as the fulcrum and the distal abutting plate as the contact point, and the structural stability and sealing strength are more effectively guaranteed.
