Safety hub capable of preventing tire from falling off during air-deficient driving

Abstract

The invention relates to a safety hub capable of preventing a tire from falling off during air-deficient driving, which comprises a tire, a wheel, a sensor, an emitter, a wheel vent hole, an adapter tube, an air tube and a wheel, the two ends of the wheel vent hole are respectively connected with the sensor, the emitter and the adapter tube, the sensor and the emitter are arranged on an outer rim of the wheel, and the other end of the adapter tube is connected with the air tube. The system further comprises a tire pressure adaptive adjustment system and a tire falling prevention system. According to the safety hub capable of preventing the tire from falling off in the air-deficient driving process, the tire pressure can be automatically adjusted according to different road conditions, and it is ensured that a vehicle runs in the optimal state.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a tire-running-proof safety wheel hub for running flat. Background technique [0002] Automobiles are outstanding creations of the industrial development of human society. Whether it is traditional fuel-driven, or the emerging electric and hydrogen-powered drives, the wheels are always supporting human travel. In recent years, the advancement of technology has brought a variety of wheel manufacturing technologies, such as mixed extrusion, semi-solid casting, multi-directional forging, etc., which can be roughly divided into three categories, namely, 1. Casting and molding processes; 2. Plastic forming process; three-stack forming process, such as 3D printing. Among them, the low-pressure casting process is widely used because of its cost-effective advantages. Most low-pressure casting adopts the center pouring method, and the size of the center gate is often limited by the pro...

AI Technical Summary

Problems solved by technology

Most of the low-pressure casting adopts the center pouring method, and the size of the center gate is often limited by the product shape of the automobile OEM and cannot be changed.

This is very unfavorable for the production of wheel products with large size and small gate. Since the gate cannot provide sufficient shrinkage capacity, the die-casting efficiency and yield will be greatly reduced. Taking a 19-inch φ50 gate as an example, the efficiency is only 10 pieces / hour, the yield rate is only 80%, resulting in extremely low profit margins for this product
