Anti-falling hub

Abstract

The utility model provides an anti-falling hub. The anti-falling hub comprises a hub body, an anti-falling gland, an elastic cushion and an air nozzle. The anti-disengaging gland is of an annular structure, is arranged on the outer side of the hub and is coaxially and detachably connected with the hub. The elastic cushion is of an annular structure and is clamped between the hub and the anti-disengaging gland. The gap between the hub and the anti-disengaging gland is reduced, and impurities are prevented from entering the anti-disengaging gland. The air tap is communicated with the position, close to the center, of the hub and communicated to the surface of a rim of the hub through spokes of the hub. The elastic cushion is arranged between the anti-falling gland and the hub, so that after the anti-falling gland and the hub are connected through the bolt, the risk that the bolt falls off after long-term use is reduced, and the gap between the anti-falling gland and the hub is filled through the elastic cushion, so that gravel is prevented from entering the space between the hub and an outer tire, and the service life of the outer tire is prolonged. Therefore, the sealing performance between the vacuum tire and the hub is ensured; the air tap is arranged at the position close to the center of the hub, so that the air tap is prevented from being damaged due to the impact of gravel.

Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to an anti-slip wheel hub. Background Art

[0002] An anti-slip wheel hub is a device installed on the axle of a vehicle. Its main function is to protect the vehicle tires and prevent the tires from falling off during driving, which may cause the vehicle to lose control. An anti-slip wheel hub usually consists of two parts: a wheel hub installed internally on the axle, and an anti-slip pressure cap installed externally on the wheel hub. When the tire twists or bounces abnormally while driving, the anti-slip pressure cap will immediately take effect and firmly fix the tire on the wheel hub to prevent it from falling off. In existing anti-slip wheel hubs, the anti-slip pressure cap is usually connected to the wheel hub by bolts. On the one hand, this connection method is prone to loosening of the bolts after long-term use. On the other hand, when used in off-road scenarios, sand and gravel can easily enter between the anti-slip pressure cap and the wheel hub, affecting the tight installation of the anti-slip pressure cap and the wheel hub. The above problems need to be solved urgently. Utility Model Content
