Airless tires with built-in tube rings and hoops

Abstract

Disclosed is a non-pneumatic tire with built-in round pipe ring and hoop. The non-pneumatic tire comprises a connected outer tire, the pipe surface of the round pipe ring sleeves at least three connected column barrels at equal intervals, two outer side walls of each of the at least three connected column barrels are connected with reverse columns, the reverse columns of the connected column barrels are parallel to a rotating shaft of the round pipe ring, at least one elastic hoop is together placed in a die cavity of a two-section die, upper cavity walls of the cross section of the die cavity are in an omega-shaped circumference, at least three groups of supporting rings which are pairwise opposite, arranged at equal intervals and vertical to an omega round ring rotating shaft are arranged on lower wall surfaces of the die cavity, at least one of same direction ends of the supporting ring groups is provided with a groove, the middle ring line of the round pipe ring coincides with the round ring of the omega-shaped cross section of the die cavity, each elastic hoop is embedded into one groove of same direction supporting ring columns, thereby, the largest circle ring and the smallest circle ring formed by the supporting ring columns and the connected column barrels around the rotating shaft of the round pipe ring can coincide, a liquid colloidal high molecular material is poured into the cavity to form the connected outer tire, and the non-pneumatic tire can be obtained.

Description

technical field [0001] The invention is about the invention of the air-free tire with built-in circular tube ring and hoop. Background technique [0002] The first major defect of existing air-free tires is that the tire hoop is not tight enough to the rim, causing the tire to separate from the rim and slide relative to the rim, which is not suitable for high-speed or heavy-duty driving. The second major defect is that the tire It is foamed. After being pressed, the cells become permanently smaller and cause the tire to sag, resulting in uneven and enlarged contact surface of the tire, and increased driving jitter and rolling resistance of the vehicle. Contents of the invention [0003] A non-pneumatic tire with a built-in circular tube ring and hoop, including a conjoined carcass, at least three connecting columns connected to the opposite column on both outer walls are equally spaced on the tube surface of a circular tube ring and connected to the column The reverse col...
