Synchronizing apparatus and method of manufacturing a synchronizing member thereof

Abstract

A synchronizing apparatus for transmissions and a method of manufacturing a synchronizing member therefore are disclosed. The synchronizing member is adapted to be shifted along a shift direction during gearshift. The synchronizing member has teeth protruding from a synchronizing member surface. The teeth have a trapezoidal cross-section along a direction perpendicular to the shift direction and are configured with a tip along the shift direction. A front apex line of the tip projects under a first angle (.phi.) from the synchronizing member surface. The tip is constituted by two inclined front surfaces extending on both sides of the apex line. The front surfaces intersect under a second angle (.gamma.) in an upper tooth surface. For making the second angle (.gamma.) as small as possible the front surfaces are provided with an upper section canted away from the tip.
