Abstract
The invention provides a protective device for a car tire, which belongs to the technical field of machines, and solves the problems that the buffer performance of the tire is reduced because only the thickness and strength of the tire are increased in the traditional protective device for the tire. The protective device for the car tire is connected with the bottom of a car body, and comprises a lifting rod, a driving piece and barrier-removing wheels, wherein the driving piece is connected with the lifting rod and can drive the lifting rod to move up and down, and the barrier-removing wheels are connected with the lower end of the lifting rod. The barrier-removing wheels connected with the lower end of the lifting rod are in contact with the ground to absorb or crush down nails, broken glass and other small barriers on the ground, thereby preventing the car tire from being punctured.
Description
Technical field
The invention belongs to field of mechanical technique, relate to the protective device for tyre in a kind of automobile.
Background technology
Motor tire is inflatable at present, and when being pressed onto nail, glass sheet, tire easily is punctured and blows out, and may cause more serious traffic accident.Tire be everlasting complicated and exacting terms under use, it is bearing various distortion, load, power and high cold service in motion, so must have higher load-carrying properties, tractive property, cushion characteristic.There are at present multiple technologies to prevent tyre explosion, but this type of technology is mainly with merely hardness or the thickness of reinforced tire itself are main, although can prevent effectively that tire is punctured, but this design direction has not only increased the cost of tire, but also has reduced the rideability of cushion characteristic and the automobile of tire.
A kind of tire [the application number 200920123852.4 with anti-nail sheet that provides as State Intellectual Property Office of the People's Republic of China, notification number CN 201525248U], comprise air-inflation tyre, air-inflation tyre comprises the inner tube of a tyre and cover tire, and anti-nail sheet is housed between the airtyred inner tube of a tyre and cover tire.Described anti-nail sheet is steel disc circular, tire-like, and anti-nail sheet adopts the high steel disc material of intensity to make.Can increase whole airtyred thickness and intensity although added this anti-nail sheet, nail be pricked less than the inner tube of a tyre, thereby reduced broken tire rate, avoid causing because of the wheel puncture generation of traffic accident; But the anti-nail sheet of dress steel disc material, not only increased the weight of tire, and greatly reduced the cushion characteristic of tire between the inner tube of a tyre and cover tire.
