Abstract

The invention discloses an explosion-proof and anti-skid emergency wheel for a motor vehicle. The wheel consists of a tire, an explosion-proof emergency wheel, an inner wheel hub seat, explosion-proof emergency wheel retaining semicircular keys, an emergency wheel conical surface mounting steel bowl, an anti-skid spacer, a retaining nut, an outer wheel hub seat, a charging connector, an overpressure control valve, a minimum air pressure alarm and an anti-skid device, wherein the explosion-proof emergency wheel retaining semicircular keys are arranged in three semicircular key grooves of the outer wheel hub seat; the explosion-proof emergency wheel is built in an emergency wheel conical surface mounting groove on the outer wheel hub seat through the explosion-proof emergency wheel retaining semicircular keys, and the anti-loose spacer and the retaining nut are arranged; the charging connector, the overpressure control valve and the minimum air pressure alarm are arranged on the outer wheel hub seat; and the inner wheel hub seat is arranged on the outer wheel hub seat. In the wheel, when a tire burst accident is suddenly encountered, the tire is instantly substituted by the emergency wheel to run so as to avoid accidents; the anti-skid device can prevent the accidents from being produced by skidding of the tire; tire demounting equipment is not required for repairing the tire; resources and energy are saved; and pollution emission is reduced.

Description

technical field [0001] The invention relates to an explosion-proof and anti-slip emergency wheel, which belongs to the wheel manufacturing engineering in the field of motor vehicle manufacturing industry. It can be widely used in firefighting, rescue, ambulance, army, aviation and various motor vehicles. Background technique [0002] In the prior art, it is common for a vehicle to run into a tire blowout accident when running normally, which brings huge losses to people's lives and property. 80,989 people were killed, 391,752 people were injured, and the property loss was 2.02 billion yuan, of which 19.1% were accidents caused by tire blowouts, 63.94% were injured and 43.38% were property losses. And on expressways, 46% of traffic accidents are caused by tire failures, of which punctures account for 70%. With the increase of car ownership, road traffic accidents have a tendency to increase significantly. In 2010, there were 3.906 million road traffic accidents in China, a ...
