Description

Amphibious tire

Technical Field

The utility model relates to the technical field of tires, specifically be an amphibious tire.

Background

A tire is a ground-rolling circular ring-shaped elastic rubber article mounted on various vehicles or machines. Generally mounted on a metal rim, and is capable of supporting a vehicle body, buffering external impact, achieving contact with a road surface and ensuring the driving performance of a vehicle. Tires are often used under complex and severe conditions, which are subjected to various deformations, loads, forces and high and low temperature effects during running, and therefore must have high load-bearing, traction and cushioning properties. At the same time, high abrasion resistance and flexibility resistance, and low rolling resistance and heat build-up are also required.

The amphibious vehicle is a special vehicle which combines the dual performance of the vehicle and the ship, can run and shuttle on the land like an automobile, and can flood and float on the water like a ship. The amphibious vehicle is mainly used in the professional fields of military affairs, disaster relief, rescue, exploration and the like, and is also used for tourism after being modified. The existing amphibious vehicle is mainly driven to run on the water surface through a propeller device arranged at the tail part, and has the problems of small water displacement and low running speed, or a water wheel blade driving mode is added on a hub of a wheel, but the amphibious power separating mode has higher cost and larger occupied space. We have therefore proposed an amphibious tire which can be applied directly to an amphibious vehicle.
