Inner pressure filling apparatus for tire-rim assembly

摘要

An inner pressure filling apparatus for a tire-rim assembly comprises a support table which is removably fixed to a base plate via a clamp and is easily replaceable; an outer cylinder which is easily replaceable and of which upper peripheral edge is inclined with respect to a vertical-direction axis of the outer cylinder; an elevator device formed by one cylinder which moves upward and downward and a plurality of springs; an air filling device for filling pressurized air into a tire of the tire-rim assembly; and a control device supplying pressurized air into the elevator device and the air filling device to move the elevator device upward and downward and controlling the elevator device and the air filling device so as to actuate the air filling device to fill pressurized air into the tire. Accordingly, the inner pressure filling apparatus as a whole becomes simple in construction and enables simple replacement of the base plate and the outer cylinder in accordance with the size of the tire-rim assembly.
