Problems solved by technology

This type of tire still has an inner and outer double-layer structure. The inner tubes need to be installed in series in advance. The structure is complex and the installation is troublesome. The manufacturing requires high processing quality of the tires. Deviations in the positions of the connecting holes and the connectors will cause adjacent tires to be plugged. If it is not in place, the inner tube cannot maintain the preset regular shape, which will affect the serial assembly of the inner tube and the normal use of the tire

Embodiment 1

[0028] Example 1 as Figure 1~2 As shown, the non-pneumatic tire includes a ring-shaped tire body 1, the outside of which is a tire crown 1-1, and the inside is a placenta 1-2. The inside of the tire body is provided with an annular inner hole 2 extending in the same direction. The radial section of the inner hole is drum-shaped, and there are multiple deformation groove groups 3 symmetrically along the length direction on both sides of the tire body (indicated by the dotted line box in the figure). Groove 4 is formed, spacer ribs are arranged between adjacent deformation grooves, the annular inner hole communicates with the deformation grooves on both sides, and the top surface of tire crown 1-1 is provided with ventilation holes 7 and concave-convex toe patterns 9 at intervals. The hole radially extends to communicate with the annular inner hole 2, and a positioning installation hole 8 is opened on the bottom surface of the placenta 1-2.

Embodiment 2

[0029] Example 2 as Figure 3-4 As shown, the non-pneumatic tire includes a ring-shaped tire body 1, the outer side of which is a tire crown 1-1, and the inner side is a placenta 1-2. The inside of the tire body is provided with a ring extending in the same direction and having a circular radial section. Shaped inner hole 2, both sides of the tire body are symmetrically provided with plural deformation groove groups 3 along the length direction (indicated by the dotted line box in the figure), and each group of deformation groove groups is composed of 5 parallel deformation grooves 4 located between the crown and the placenta , spacer ribs are provided between adjacent deformation grooves, spacer ribs are also provided between the deformation grooves and the annular inner hole so that the two are independent of each other, and the top surface of the crown 1-1 is provided with air holes 7, and the air holes are radially Extending and communicating with the annular inner hole 2,...

Embodiment 3

[0030] Example 3 as Figure 5-6 As shown, the non-pneumatic tire includes a ring-shaped tire body 1, its outer side is a tire crown 1-1, and its inner side is a placenta 1-2. Shaped inner hole 2, both sides of the tire body are symmetrically provided with plural deformation groove groups 3 along the length direction (indicated by the dotted line box in the figure), and each group of deformation groove groups is composed of 5 parallel deformation grooves 4 located between the crown and the placenta Spacer ribs are provided between adjacent deformation grooves, spacer ribs are provided between the deformation groove 4 and the annular inner hole 2 to make the two independent of each other, and the top surface of the crown 1-1 is provided with vent holes 7 and concave-convex toes The vent hole radially extends to communicate with the annular inner hole 2, and the bottom surface of the placenta 1-2 is provided with a positioning installation hole 8.

Abstract

The invention belongs to the technical field of vehicle fittings, in particular to an inflation-free tire. The traditional inflation-free tire-sheet combined tire needs to connect in series and mount an inner tube in advance, has complicated structure, troublesome mounting and high processing requirements for tire sheets; and the position deviation of a connecting hole and a connecting piece can cause the unsuitable splicing of adjacent tire sheets so that the series connection assembly of the inner tire and the normal use of the tire are influenced. The invention provides the inflation-free tire which has no need of on-site series-connection mounting, simple manufacture process and low cost, and comprises a circular tire body with a tire tread at the outer side and a tire holder at the inner side; the tire body is internally provided with a circular inner hole extending in the same direction and symmetrically provided with a plurality of deformed groove groups at both sides along the length direction; each deformed groove group comprises a plurality of parallel deformed grooves arranged between the tire tread and the tire holder; and a separation rib is arranged between every two adjacent deformed grooves. The invention has favorable elasticity and working reliability, no need of on-site series-connection mounting, rapid replacements, low processing requirement and little manufacture cost.

Description

【Technical field】 [0001] The invention belongs to the technical field of vehicle accessories, in particular to an air-free tire. 【Background technique】 [0002] Pneumatic tires used on common vehicles are covered with a pneumatic inner tube by the outer tire. The applicant previously applied for a non-inflated tire combined tire that can be used without inflation (patent number: ZL200610053262.X). The tires are connected in series, and the two sides of the tires are provided with connecting holes and connectors that can be plugged and matched. This type of tire still has an inner and outer double-layer structure, and the inner tube needs to be installed in series in advance. The structure is complex, the installation is troublesome, and the manufacturing requires high processing quality of the tire. The deviation of the connection hole and the position of the connector will cause adjacent tires to be plugged. If it is not in place, the inner tube cannot maintain the preset...
