Abstract

Hub for removable wheels characterized by comprising a cylindrical and hollow central body for passage of the wheel axle whose body is internally jacketed by an elastic and self-lubricating bushing ending at both ends by separate discs that support the spokes of the wheels and of which one specifically, the outside according to the normal position of the bushing has attached to its external face a plate displaceable by the action of an angled finger that penetrates through a notch open in the disc itself and whose plate carries on its surface an eyelet torn by a narrowing in its lower part and which corresponds to the axial perforation of the shaft-bearing body, the aforementioned plate being also provided with a slot that is elongated vertically and provided in its lower part by a supporting rivet secured to the disc wall and which limiting it in its elevated position as in the descent movement that during its function this effect is complemented by a wire rope with a rounded general structure that carries in its lower part a ripple that supports the rivet of the disc and in the upper part two angular notches that make it in the lower part. Some eyelashes like inverted hooks that are prevented in the upper part of the same plate and slightly emerging from its structure, the latter being the one that keeps the plate in its elevated position and the one that has to be overcome in order to force it to descend through the pressure exerted on the repeated drive finger.
