ABSTRACT:
The present invention relates to a synchronizer for automobile transmissions. The invention provides a synchronizer in which the stroke of the shift lever is shorter for the same synchronizing time and the shift lever is operated by a smaller operating force to give convenient operation. By forming a friction surface at the outer circumference of the sleeve, the friction is located at the farthest position from the center line of the synchronizer so that the friction force is increased. At the same time, the pitch circle diameter of the power transmission spline is the largest so that the width of the synchronizer is reduced and the time required for synchronizing reduced. Also, the torque required in operating and the operating stroke are reduced remarkably whereby the enhanced performance synchronizer for automobile transmission provided.
