摘要： A unit for rapid deployment and retraction of chain traction systems for vehicles includes a pneumatic cylinder having a cylindrical chamber enclosing a piston that is pneumatically-movable bidirectionally. A control rod coupled at one end to the piston passes through an end of the chamber and is coupled to a rack linearly movable within a sealed, grease-containing case. The rack is formed from a series of equally-spaced roller pins secured between parallel walls of a rack frame. The roller pins of the rack engage a sprocket affixed to a rotatable shaft to which is rigidly coupled an actuator arm of the rapidly-deployable vehicle ice and snow chain traction system. As the rack is moved back and forth, the actuator arm swings through an arc that—depending on the displacement of the control rod and the length of the rack, can be greater than 180 degrees.
