Abstract:
A braking system for mitigating the linear motion of an object, the object having an axis, the linear motion being coaxial with the axis, the braking system comprising:a tube, the tube positioned coaxially around the object; at least one brake shoe, the at least one brake shoe adapted to be positioned in a free space defined by the outer surface of the object and the inner surface of the tube; a coating of low-friction material adhered to a portion of the inner surface of the tube and interposed between the inner surface of the tube and the at least one brake shoe; means attached to the object for limiting the lateral movement of the at least one brake shoe relative to the object while permitting the radial movement of the at least one brake shoe relative to the object; and means for urging the at least one brake shoe in an outward radial direction, wherein the at least one brake shoe is put in frictional contact with the low-friction material, whereby, when the object is moved in a linear direction, the braking system mitigates the linear motion of the object.
