ABSTRACT:
A sintered selector or sliding sleeve, or gear shift sleeve, has internal claw toothing. The individual teeth are delimited on their ends with secondary surfaces having ends that extend radially inward and outward from the root circle of the inner tooth surfaces. The novel geometry of the secondary surfaces extending radially outward from the root circle provide advantages in the manufacture of such selector sleeves by powder metallurgy, compared with those having prior art tooth geometries.
