Abstract

The invention relates to an automatic inflation pump which can automatically perform air inflation on a tire with air leakage during the driving process of a vehicle and further ensure that the vehicle can be driven continuously under special situations. A pump body is connected to a wheel hub of a wheel; an inflation cylinder and a brake cylinder, which are vertically communicated, are formed inthe pump body; and pistons and springs are respectively arranged in the inflation cylinder and the brake cylinder. The inflation cylinder is communicated with the tire through a one-way valve and an air conveying pipe, and the brake cylinder is communicated with the air conveying pipe through an air guide pipe. A driving ring is connected to a steering knuckle, through holes connected with the inflation cylinder are formed on the wheel hub and a brake disc, and a transmission rod is arranged in the through holes. When the air leakage occurs during the tire during driving, the transmission rodand the inflation piston can move in a reciprocating manner under the common action of the driving ring and the spring, and air can be further inflated into the tire. When the air pressure in the tire and the air conveying pipe achieves a rated value, the piston in the brake cylinder can enter into the inflation cylinder under the pushing of the air pressure, thus the reciprocating movement of the piston in the inflation cylinder can be prevented.

Description

technical field [0001] The invention relates to an automatic inflation device for a vehicle, in particular to an automatic air pump which can automatically inflate a leaked tire when the vehicle is running, so as to ensure that the vehicle can continue to run under special circumstances. Background technique [0002] At present, once gas leakage occurs in known automobile tires, they can only be stopped for repair and cannot continue to travel. Contents of the invention [0003] In order to overcome the deficiency that the existing automobile tires can only be stopped for repair once gas leakage occurs, and cannot continue to drive, the invention provides an automatic air pump, which can automatically repair the air-leaked tires during the running of the vehicle. Inflate to ensure that the vehicle can continue to drive under special circumstances. [0004] The technical solution adopted by the present invention to solve its technical problems is: the present invention com...
