Abstract
Machine for unseating a tire bead from a wheel, comprising a stand designed to rest on the ground, a bearing plate for the wheel, and a bead unseating tool which is connected to a tool bearing structure mobilely mounted to the stand. The machine comprises a pneumatic actuator for setting the tool bearing structure in motion in order to operate the tool, and a shock absorber connecting the tool bearing structure to the stand in order to damp the movement of the tool bearing structure, particularly at the moment at which the tire bead unseats from the rim of the wheel.
Claims10
A machine for unseating a tire bead from a wheel, comprising:
- a stand designed to rest on the ground,
- a bearing plate against which to rest one lateral side of the wheel,
- a bead unseating tool facing the bearing plate and mounted to a tool bearing structure, said tool bearing structure being mobilely mounted on the stand,
- an actuator connected to the stand and to the tool bearing structure and configured to set the tool bearing structure in motion so as to move the bead unseating tool toward the bearing plate,
- said actuator is a solely pneumatic actuator,
- wherein
- the bead unseating machine further comprises a telescopic shock absorber, a cylinder of which is connected to the tool bearing structure or to the stand and a piston of which is connected respectively to the stand or to the tool bearing structure via a piston rod,
- and wherein the shock absorber has a damping coefficient that differs according to whether the shock absorber is acting in one direction or in the opposite direction.
