[0002] At present, in the actual application of non-pneumatic tires connected to their rims, they are mainly divided into one-piece forming and split-type card groove connection. The processing and manufacturing process of integrally formed non-pneumatic tires is relatively complicated, while the existing split-type Most of the non-inflatable tires connected by grooves are connected by conventional mechanical connection methods such as splines and dovetail grooves between the support body and the rim. It is easy to cause local premature thermal deformation, slippage, etc., or at the cost of loss of driving speed to ensure the safety and reliability of the tire

A non-pneumatic tire comprises a support body and a wheel rim which matches the support body. Several fir-tree type tenons are arranged at the inner side of the support body. The tenon is provided with tooth parts which are raised along the circumferential direction of the support body. The wheel rim is provided with tenon grooves which match the tenons such that the wheel rim and the support bodyare mutually fixed in the circumferential direction of the support body. The tenon groove is provided with tooth grooves which can match the tooth parts so as to limit relative movement of the support body and the wheel rim in the circumferential direction of the support body. By the cooperation between the fir-tree type tenons and the tenon grooves and the design of tooth angle and size, the support body and the wheel rim can be tightly cooperated, thus effectively preventing too early thermal deformation and falling-off and preventing the wheel rim from ''biting'' the support body. With thearrangement of the fixed part, axial relative displacement between the support body and the wheel rim can be prevented, thus meeting various requirements of a split type non-pneumatic tire during high-speed running.
Description
technical field [0001] The invention relates to a vehicle tire, in particular to an air-free tire. Background technique [0002] At present, in the actual application of non-pneumatic tires connected to their rims, they are mainly divided into one-piece forming and split-type card groove connection. The processing and manufacturing process of integrally formed non-pneumatic tires is relatively complicated, while the existing split-type Most of the non-inflatable tires connected by grooves are connected by conventional mechanical connection methods such as splines and dovetail grooves between the support body and the rim. It is easy to cause local premature thermal deformation, slippage, etc., or at the cost of loss of driving speed to ensure the safety and reliability of the tire. [0003] Therefore, a kind of non-pneumatic tire with split connection that can be used under the high-speed running state is urgently needed by those skilled in the art at present. Contents of ...
