ABSTRACT:
The present invention relates to a shift fork (10) for a vehicular transmission. The shift fork (10) utilizes a hub portion (12) from which an offset arm (16) extends radially outwardly to terminate in an outer end portion (18). One or more contact pads (22 and 44) are supported from the outer end portion (18) of the offset arm (16), and the tines (20) extending from the offset arm (16). The contact pads (22 and 44) present longitudinally facing wear surfaces (24 and 46). Each of the longitudinally oriented wear surfaces (24 and 46) has an angularly inclined portion (32 and 48). The inclined portions (32 and 48) each diverge outwardly at an angle (phi or theta) which equals the angle at which the offset arm (16), or each tine (20), deflects at the location along the contact pads (22 and/or 44) where each wear surface (24 and/or 46) is subjected to a predetermined load.
