Construction in reaction rod

Abstract

An assembly for a reaction rod for shafts of automotive vehicles, more specifically, to be applied in heavy vehicles provided with pneumatic or mixed suspension, basically composed of a box provided in the end of a bar, being that this box has an internal housing in the cylindrical or spherical form where is introduced a pin with a segment also cylindrical or spherical, where is a vulcanized rubber confectioned by injection and the pin is fixed in the interior of the box by retaining rings. The reaction rod thus composed has in the injected rubber that is vulcanized in the cylindrical or ball type segment of the pin, a recess or channel that in a version is provided in the entire circumference of the injected rubber that is vulcanized on the pin, with the objective of providing a relief in small radial and angular movements, in all senses of direction, which relief is progressively reduced in the proportion that the radial and angular movement increases. In a second version, the recess or channel provided in the circumference of the injected rubber is segmented so as to allow the relief that is progressively reduced in the radial and angular movement, only in specific directions, being that in other directions also specific where the recesses or channels are not provided in the injected rubber, there is no relief and the displacement effort is uniform as from the geometrical shaft of the cylindrical or ball type pin relative to the box of the reaction rod until its displacement limit.
