Description

Adsorption type tire inflation auxiliary device

Technical Field

The utility model belongs to the technical field of tire and rim mounting and inflation, and particularly relates to an adsorption type tire inflation auxiliary device.

Background

Most of the car tires on the market at present are tubeless vacuum tires, and a large number of test tests are needed to be carried out on the tire products in the development and production stages so as to monitor the performance of the products. The tire is mounted on the rim and inflated to a certain air pressure, and when most of the tires are mounted on the rim and inflated, the bead parts on two sides are slightly contacted with the rim to form a closed space in the tire, and then the tire is inflated to the closed space in the tire through the inflating valve. With the increase of the air pressure of the airtight space inside the tire, the contact between the rim and the rim at the bead parts at the two sides is gradually tight, and then the bead parts at the two sides of the tire can pop up suddenly and cling to the rim edge. Inflation and springing of a tire is a very common inevitable phenomenon when installing a tire. However, in some tires with larger flat ratios (also called aspect ratios), for example, 235/85R16 specification tires, because the flat ratio reaches 85%, the bead portions of the tires are far from the tread, and the bead portions on both sides of the tires are easy to gradually deform and get close after being placed for a period of time, so that the bead portions on both sides of the tires are not contacted with the rim after the tires are mounted on the rim, and the tires and the rim cannot form a closed space, so that air leakage occurs when the tire is inflated through the valve, and the bead portions on both sides cannot spring up to contact the rim, so that subsequent test experiments cannot be performed.

Aiming at the problem that part of the tire with larger flat ratio is close to the tire opening and can not be mounted on the rim for normal inflation, two common solutions are provided: (1) The burst inflation device is adopted, namely, a high-pressure air storage tank is adopted, high pressure is instantly released at the seam allowance position of the tire in air leakage, the tire is promoted to bounce at one instant, then the inflation work is normally completed, the method can only be used for the tire with a lighter seam allowance closing degree, the success rate is lower, multiple attempts are needed, and the potential personal injury risk is higher by using the high-pressure air storage tank; (2) The steel pipe is used for supporting, namely, a plurality of steel pipes are forcibly supported at the tire bead position, so that the tire is kept in a supporting state and is parked for a period of time, and then the tire is mounted on the rim for inflation, however, the steel pipe may damage the tire lining layer or scratch the tire lining layer when the support is unstable, so that the expected service life of the tire is greatly reduced, the test result is influenced, and the tire is at least required to be supported for a plurality of hours to have an effect, so that the test efficiency is greatly influenced.
