New description: • [New technical field] • This creation belongs to the technical field of transportation, especially the tires used in small low-speed vehicles such as electric scooters. [Prior Art] An electric scooter is a slow-moving vehicle with a maximum speed of about 15 kilometers. It is used as a means of transportation for people with reduced mobility (such as physical disabilities or the elderly) or for driving on a golf course. Solid tires, not like the pneumatic tires of several locomotives. Generally, the entire tire j 4 0 ) is made of polyphosphonate ((9), hereinafter referred to as PU) as shown in the third figure, but has a lack of grip. Therefore, the manufacturer does not count a tire as shown in the fourth figure, which includes a circular metal wheel frame portion (5 〇) and a bead portion (5 包覆) wrapped around the outer circumference of the rim portion (5 〇) (5 5), wherein the annular outer peripheral wall of the rim portion (5 〇) is provided with a radially protruding flange (5 1 ), and a hollow portion (5 2 ) is disposed on the flange (5), The tire portion (5 5 ) is made of an elastomeric polyurethane s (8) ast〇mer polyurethane, hereinafter referred to as an elastomer PU), and is coated on the flange (5 i ) and the hollow portion ( 5 2 ). Although the grip is better, however, due to the high degree of looseness of the bullet, month and PU, the long time required for aging during manufacture results in a cost that is more south than its weight, plus the middle metal rim portion (5 0) The formation of a large load is likely to cause the battery power consumption of the electric scooter. As can be seen from the above, the tires of the existing two scooters have their own inability to change, and further improvements are necessary. [New content] 4 M338773 In view of the lack of the above two electric-generation cattle-powered scooters, the main purpose of this creation is to provide a two-wheeled combination. Wheel I ribs, and improves the missing wheel base; the above purpose 'This creation 4: φ >> y, 主要 The main technical means is to provide a cone tire, which is a solid tire, including: In another inner tire part, the center|there is a wearing ^, copper tooth hole, and the outer peripheral wall of the 裱 shape is provided with an outer ring surface; - an elastic tire part, the body _ body is set on the outer ring surface, the inner tire part and the elastic table The tire part is made of polymer elastic material, and the elasticity and density of the elastic tire part are higher than that of the inner tire part, and the elastic clamp is equal to or less than one-half of the volume of the whole tire. After the implementation of the above technical means, the specific benefits that can not be obtained in this drama - ^7 · 1. Since the creation system includes two kinds of elastic materials of the polymer, and the elastic part of the outer layer is superior to the inner tire part, @ Since the elastic tire part is in contact with the ground, the grip is strong, the wear resistance is ancient and has good comfort. 0 2 Since most of the volume of the creation is the inner tire portion with a small density, The elastic tire part only occupies a small part of the surface. Therefore, the entire tire is light in weight and does not increase the battery power consumption of the electric scooter. As can be seen from the above, the design of the present invention can improve the solid tires made of the above two single materials, and combine the advantages of the two existing tires. [Embodiment] Please refer to the first and second figures. The two-material tire package 5 M338773 includes an inner tire part (1 η, ^ u ) and a drop-type tire part (2 Ο).
