Problems solved by technology

However, for low-speed vehicles, the grip of the tires is too large, which will increase the friction of the vehicle, especially when going uphill.
Therefore, it is not conducive to implementation, that is to say, it increases the energy consumption of the user during the driving of the car, and it is more laborious to push it by hand.

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] What the present invention discloses is a kind of low-speed flat air-free tire, and tire described in the present invention can be single-ply solid tire, as figure 2 As shown, it is the first preferred embodiment of the present invention, which is a single-layer solid tire 1, and an arc-shaped protrusion 11 is formed on the side of the solid tire 1 that is in contact with the ground (ie, the tread side). , the two sides 12 of the arc-shaped protrusion 11 gradually go down to the two sides 15 of the tire. Because the tire of this structure only has the arc-shaped protrusion 11 at the position in contact with the ground, the contact area with the ground is greatly reduced compared with the traditional solid tire, so the grip force is relatively small, and the friction force with the ground is reduced, so that the implementation ...

Abstract

The invention discloses a low-speed flat inflation-free tire. An arc bump is formed on one lateral surface (which is in contact with the ground, namely one side of a tire tread) of the outer surface of the tire. When the tire is in contact with the ground through the arc bump in the driving process, the area of the low-speed flat inflation-free tire is greatly reduced when being compared with an entire tire tread, so that the contact area of the ground is further greatly reduced when being compared with the conventional inflation-free tire. Therefore, the road loading force is quite small; and the friction between the low-speed flat inflation-free tire and the ground is reduced, so that the labor is saved in the pushing process.

Description

technical field [0001] The invention relates to a tire, especially a low-speed flat non-pneumatic tire. Background technique [0002] For low-speed vehicles that only need to be pushed forward by hand, such as baby carriages and wheelchairs, the tires generally adopt non-inflatable tires, and the non-inflatable tires are more convenient to use because they do not need to be inflated. However, the shape of air-free tires is developed from pneumatic tires, so the cross-sectional shapes of existing air-free tires are mostly similar to pneumatic tires, such as figure 1 As shown, it is a typical PU solid tire. The side of the cross-section of the traditional non-pneumatic tire in contact with the ground is usually similar to an ellipse or a semicircle. The tire with this cross-section has a larger contact area with the ground, so the grip is also greater. For vehicles traveling at high speeds, the tires must have sufficient grip, otherwise the vehicle is prone to slipping. How...
