An improved snychronizer for damage control of synchronizer ring

摘要

This invention relates to an improved synchronizer pack of synchronizer comprising a synchronizer hub fitted with synchronizer rings accommodated inside a sleeve, wherein the synchronizer ring is integrally provided with a plurality of lugs on its boss area for protection against damage due to engine torsional vibration. It is associated with the following advantageous features:- - Prevention of damage to synchronizer ring owing to engine torsional vibration. - Improved thrust contact area between synchronizer ring and key, thereby reducing torsional impact between synchronizer ring and key. - Reduction of the torsional impact by reducing the torsional acceleration of ring. - Reliable and efficient.
