Abstract

PURPOSE: To prevent the deterioration of torque due to the abrasion, by bringing the screwed side of the contact face between a synchronizer ring and a gear cone of a BOLG-WARNER synchronous device to the gear cone side contrally with the conventional one while making the screw land face with harder material.
CONSTITUTION: In an embodyment applied on a BOLG-WARNER synchronous device for a change gear, a screw isn't made on the inner diameter face F1 of a synchronizer ring (R) while a screw (S) is made in the tapered face F2 at the outer- diameter section of a gear cone (C) to be engaged with said ring (R). Consequently the conventional defect than when the tapered faces are pressed from both sides and contacted the inertia lock performance represented by the frictional force or the torque is lowered by the abrasion of the screw land face can be improved. Since the screw isn't made in the inner diameter face of the synchronizer ring made of soft material the effective face is increased, while since the screw is made in the outer- diameter section made of hard material to improve the durability at the top face of screw the performance can be maintained for long term.
