Inner supporting body of tire

Abstract

The invention provides an inner supporting body of a tire. The inner supporting body comprises a first joint and a second joint, wherein the first joint is provided with a first bulged portion, the second joint is provided with a recessed portion matched with the first bulged portion, and the first bulged portion is matched with the recessed portion, so that the first joint and the second joint can be mutually fixed. By adopting a plugging connection way, the connection is firmer, a wedged block is used for fastening, the loosening can be more easily prevented, a bolt is adopted for the secondary fastening after the fixation of the wedged block, the firmness in connection can be ensured, the stress concentration can be effectively prevented by matching a corresponding end surface and a fitting surface and arranging the arc bulged portion, and the durability of the inner supporting body can be ensured.

Description

technical field [0001] The invention relates to the field of tires, in particular to a tire inner support body. Background technique [0002] At present, when the vehicle runs out of air (tire pressure is lower than the standard tire pressure) or is pierced by other sharp objects (such as nails, etc.), as the tire pressure drops, the friction between the tire and the ground increases exponentially, and the tire temperature rises sharply. High, the tire becomes soft and the strength drops sharply. In this case, if the vehicle is driven at high speed, it may cause a tire blowout; if a tire of the vehicle blows out, it will cause the vehicle to deviate. If the driver cannot respond correctly It will cause the vehicle to collide with the green belt around the road, or even collide with the vehicle in the same direction or the opposite direction, causing huge personal injury or property loss. In the current prior art, there has been an annular support device, which consists of a ...

[0002] At present, when the vehicle runs out of air (tire pressure is lower than the standard tire pressure) or is pierced by other sharp objects (such as nails, etc.), as the tire pressure drops, the friction between the tire and the ground increases exponentially, and the tire temperature rises sharply. High, the tire becomes soft and the strength drops sharply. In this case, if the vehicle is driven at high speed, it may cause a tire blowout; if a tire of the vehicle blows out, it will cause the vehicle to deviate. If the driver cannot respond correctly It will cause the vehicle to collide with the green belt around the road, or even collide with the same direction vehicle or reverse vehicle, causing huge personal injury or property loss. In the current prior art, there has been a ring support device, which consists of a The ductility is poor. It is composed of a ring-shaped support body and abutment feet. It also has a two-piece structure. Due to the unreasonable structure, it is easy to cause the installation to be unfastened, and then cannot effectively play a supporting role, or it is easy to cause stress concentration.
