Abstract
The utility model belongs to wheels, particularly to a self-inflating wheel, which comprises a cover tire, a tire tube and a rim. The self-inflating wheel is characterized in that a small air cylinder is installed on the rim and among the tire tube, the cover tire and the rim; the air cylinder is fixed on the rim through a fastening screw; a pneumatic valve is arranged in the fastening screw; and a return spring is installed on the small cylinder. When the air pressure inside a tire is insufficient, the part of the wheel where the air cylinder is installed can deform when being in contact with the ground, so that a piston is pushed upwards to inflate the tire, and when the wheel proceeds, an air pressure rod of the small air cylinder leaves the ground, and the return spring on the air cylinder enable the piston to the original position. Therefore, the tire can be inflated continuously, so that a certain air pressure is maintained in the tire. The utility model is suitable for the wheels of electric bicycles, electro-tricycles and motorcycles.
Description
Technical field
The utility model belongs to the wheel class, specifically is the self-inflatingPads wheel of a kind of Electrical Bicycle, motor bike.
Background technology
Usually Electrical Bicycle, electro-tricycle, bike wheel in use often leak air situation and can't ride, and can only lean on implementation, bring great inconvenience to the user, still do not have good terms of settlement at present.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of reasonable in design, easy to use, have an automatic identification atmospheric pressure state function, and can inflate while riding simultaneously, thereby make tire can keep the self-inflatingPads wheel of certain air pressure.
The technical solution of the utility model is as follows:
A kind of self-inflatingPads wheel comprises cover tire, the inner tube of a tyre, rim, it is characterized in that: a little inflator is housed on the rim, little inflator is between the inner tube of a tyre, cover tire and rim, stingy tube is fixed on the rim with check screw, has air pressure valve in the check screw, on the little inflator retracing spring is housed.When low tyre, the position of wheel installation inflator will produce distortion when contacting with ground, thereby promote the piston upward movement and give inflation of tire, when wheel moves on, stingy tube atmospheric pressure pole built on stilts, the retracing spring on the inflator returns to the position with piston, comes and goes successively, constantly inflate, thereby make wheel keep certain air pressure to wheel.
Have air pressure valve in the check screw of the present utility model, when under the effect of piston at retracing spring during upward movement, this valve is opened automatically, to the cylinder tonifying Qi.
The utility model wheel under the situation that does not have gas leakage, is ridden with normally tire is the same, without any the sensation of discomfort in use.Only just work automatically under the gas leakage situation makes tire keep constant voltage, need not reach air pressure and keep and self-aerated dual purpose for filling sudden and violent tire worry.The utility model is simple in structure, and is easy to use, the dispense with parking tonifying Qi, and low cost of manufacture, practical.
Description of drawings
Fig. 1 is the utility model structural representation.
Structural representation when Fig. 2 is the inflation of the utility model self-inflatingPads wheel.
Structural representation when Fig. 3 is the utility model inflator piston reset.
The specific embodiment
As shown in Figure 1, a kind of self-inflatingPads wheel, comprise cover tire 1, the inner tube of a tyre 2, rim 3, it is characterized in that: be fixed with a stingy tube 4 on the rim 3, little inflator is between the inner tube of a tyre, cover tire and rim, stingy tube 4 usefulness check screws 5 are fixed on the rim 3, have air pressure valve in the check screw 5, on the stingy tube 4 retracing spring 6 are housed.When low tyre, as shown in Figure 2, the position that wheel is installed inflator will produce distortion when contact with ground, thereby promotes the piston upward movement to inflation of tire, when wheel moves on, and stingy 4 atmospheric pressure pole built on stilts; As shown in Figure 3, retracing spring on the inflator 6 returns to the position with piston, comes and goes successively, constantly gives inflation of tire, thereby makes tire keep certain air pressure.
The utility model is suitable for Electrical Bicycle, electro-tricycle, bike wheel.
Rim of the present utility model can be steel ring, aluminium circle etc.
Claims (2)
1, a kind of self-inflatingPads wheel comprises cover tire, the inner tube of a tyre, rim, it is characterized in that: a little inflator is housed on the rim, little inflator is between the inner tube of a tyre, cover tire and rim, stingy tube is fixed on the rim with check screw, has air pressure valve in the check screw, on the little inflator retracing spring is housed.
