Automobile synchronizer is the key position of mechanical gear transmission speed variator, uses lock unit gearshift light and flexible, it is possible to avoid between cog to impact.The most conventional inertia synchronizer is mainly made up of soldered tooth set, synchronous ring, toothholder etc., the inner conical surface relying on synchronous ring contacts generation friction with gear-wheel gear-ring male cone (strobilus masculinus) to be joined, make tooth set to be engaged the most synchronize with gear ring by conical surface friction, a kind of locking effect can be produced again simultaneously, prevent gear from engaging at advanced in unison row.Visible, synchronous ring is the critical component of gear shift operation in lock unit.In existing lock unit, the structure of synchronous ring is as shown in Figure 1, matrix 100 including annular, matrix 100 is provided with internal taper hole 200, it is positioned at the side of matrix 100 of internal taper hole 200 bigger diameter end with flange section 1001, the circumferential periphery of flange section 1001 is provided with spline tooth 300, spline tooth 300 docks with in lock unit, the spline tooth tooth of toothholder is relative with tooth, the spline tooth of soldered tooth set can sliding in the teeth groove between teeth groove and the synchronous ring spline tooth 300 between toothholder spline tooth, this synchronous ring structure can transmit big torque and have good dynamic connection guidance quality, but in the substrate flange part with internal taper hole, it is provided with a circle spline tooth, manufacturing process is more complicated, sometimes for Special Equipment, relatively costly.
Summary of the invention
The applicant improves for disadvantages mentioned above of the prior art, it is provided that a kind of simple in construction, lock unit simple for production, with low cost and synchronous ring thereof.
Technical scheme is as follows:
The synchronous ring of lock unit of the present invention, including the matrix of annular, matrix is provided with internal taper hole, and the one end of the matrix being positioned at internal taper hole bigger diameter end is provided with flange end, and the circumferential periphery of flange end is evenly equipped with at least three width profile of tooth locking projection.
Its further technical scheme is:
At least three locating convex block or at least three detent it is evenly equipped with on the outer circumference surface of the matrix between described internal taper hole narrow end and flange end.
Lock unit of the present invention, including toothholder, soldered tooth set is socketed on toothholder, and is actively coupled by spline with toothholder, and the both sides of toothholder are equipped with synchronous ring；Synchronous ring includes the matrix of annular, matrix is provided with internal taper hole, the one end of the matrix being positioned at internal taper hole bigger diameter end is provided with flange end, synchronous ring is connected with the inner peripheral surface of toothholder by the outer circumference surface between internal taper hole narrow end and flange end, the male cone (strobilus masculinus) of conical ring and the inner conical surface floating connection of the internal taper hole of synchronous ring, engage gear ring to be connected with the end face spline fitted of conical ring by its end face groove, the circumferential periphery of the flange end of synchronous ring is evenly equipped with at least three width profile of tooth locking projection, and on the inner peripheral surface of soldered tooth set, the position of corresponding described locking projection is provided with fit.
The technique effect of the present invention:
nullSynchronous ring of the present invention is by improving the structure of existing synchronous ring，With the circle spline tooth on the wide profile of tooth locking projection alternative synchronization ring flange end of minority quantity，After synchronous ring realizes being connected with the inner peripheral surface of toothholder in lock unit by the outer circumference surface between internal taper hole narrow end and flange end，During gearshift，The spline tooth in soldered tooth set in lock unit can sliding in gap between the teeth groove between external spline teeth and the locking projection on flange end on toothholder，At least three locking projection is that the spline tooth in being overlapped by soldered tooth is divided at least three pieces of regions，So when soldered tooth set is mobile，Spline tooth in overlapping soldered tooth carries out block guiding，While realizing guide effect，The locking projection of minority quantity substitutes the spline tooth of flange end one circle，Make synchronous ring and use the synchronizer structure of synchronous ring of the present invention the simplest、Make the easiest，And reduce cost of manufacture；On the other hand, while soldered tooth is overlapped mobile guiding, locking projection equally plays the locking effect preventing gear from engaging at advanced in unison row；It is evenly equipped with at least three locating convex block or at least three detent on the outer circumference surface of the matrix between internal taper hole narrow end and flange end, improves the positioning precision of synchronous ring of the present invention and toothholder.
