Abstract
In order to operate with maximum efficiency and safety, this device comprises two tubular assemblies which bear a jaw-holder block and can slide one within the other. An interlock system is arranged between the tubular assemblies and the jaw-holder block in order to control the sliding of the inner tubular assembly by that of the outer tubular assembly. The tire push member borne by the inner tubular assembly can push the sidewall of the tire back only when the fixed and movable jaws strongly clamp the flange of the rim. This device is preferably operated by a pneumatic impact wrench.
Claims12
A device for removing a tire from a rim having at least one circumferential flange, said device, which comprises a fixed jaw, a movable jaw cooperating with the fixed jaw and a tire push member which is driven by a mechanism which assures its axial displacement with respect to the jaws, being characterized by the fact that it comprises outer and inner tubular assemblies which bear a jaw-holder block and are engaged one within the other and are axially slidable, limited by stops, with respect to each other and with respect to the jaw-holder block;
- by the fact that one end of the outer tubular assembly bears an articulation for the movable jaw while its other end is fastened to a motor which controls the axial sliding of the two tubular assemblies;
- by the fact that the inner tubular assembly bears the tire push member;
- and by the fact that an interlock system is interposed radially between the inner tubular assembly, the jaw-holder block and the outer tubular assembly in order to make the sliding of the inner tubular assembly subject to the sliding of the outer tubular assembly.
