Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
As illustrated in fig. 1 and 2, a kind of light card class booster type synchronizer, it comprises synchronizing ring 3, engage ring gear 4, tooth hub 2 and the tooth engaged with described tooth hub 2 overlap 1, and synchronizing ring 3, engage ring gear 4, tooth hub 2 and tooth cover 1 equal coaxial line, the inwall of described tooth cover 1 is provided with spline and on described spline, has axial chute 11, described slide block 6 is placed in this chute 11, the outer side wall of described tooth hub 2 is provided with the alligator of the spline engagement of to overlap 1 with described tooth, described synchronizing ring 3 is overlapped 1 by slide block 6 and described tooth and is linked, one end face of described joint ring gear 4 is provided with concentric tapered collar 41, the external annulus of described tapered collar 41 and the internal ring wall 32 of described synchronizing ring 3 are fitted, the internal ring wall of described synchronizing ring 3 is provided with screw thread, this screw thread is for increasing the frictional force between tapered collar 41 and synchronizing ring 3, the internal ring wall 32 of described synchronizing ring 3 is also cone-shaped, and with the positive of described tapered collar 41 external annulus,
As shown in Figures 4 and 5, the first side end face that described slide block 6 comprises upper-end surface and is adjacent, two symmetrical sides places of described upper-end surface are provided with two symmetrical inclined-planes, described inclined-plane is the second cooperation inclined-plane 62, described first side end face has inserting groove along this direction, the first side end face vertical, two cell walls of this inserting groove are the first cooperation inclined-plane 61, and two described first coordinate the spacing between inclined-planes 61 to offer direction along inserting groove to reduce gradually;
The other end adjacent with the upper-end surface of described slide block 6 is the second side end face 63, and described second side end face 63 is inclined-plane, and fits with the bottom land of described chute 11 in this second side end face 63;
As shown in Figure 6, axially tooth hub groove is had along it in the edge of described tooth hub 2 outer side wall, and have several tooth hub groove around two edges of described tooth hub 2 are staggered, at the bottom of this tooth hub groove slotless, the two ends of described tooth hub 2 are respectively equipped with a synchronizing ring be mated 3, spacing between two cell walls 21 of described tooth hub groove is offered direction along it and is reduced gradually, second of described slide block 6 coordinates inclined-plane 62 to be placed in described tooth hub groove, and described second coordinates inclined-plane 62 to be acute angle with cell wall 21 angle of corresponding tooth hub groove;
The bottom land of two described tooth hub grooves has the positioning hole 22 into blind hole, spring 5 is provided with in described positioning hole 22, and one end of this spring 5 abuts with described slide block 6, this spring 5 set up effect slide block 6 being served to location, this slide block 6 is better coordinated with synchronizing ring 3 and tooth hub 2;

The working principle of the present embodiment:
When tooth cover 1 axially moves under the promotion of selector fork power, the slide block 6 be now placed in this tooth cover 1 will be pushed and axially move;
Meanwhile, slide block 6 promotes synchronizing ring 3, the relation of conical surface friction is there is between the tapered collar 41 of synchronizing ring 3 internal ring wall 32 now and the joint ring gear 4 in rotating, and there is certain relative rotation speed poor between synchronizing ring 3 and joint ring gear 4, so the joint ring gear 4 now rotated rotates around its axis together with synchronizing ring 3, the protruding sidewall 31 of synchronizing ring 3 coordinates inclined-plane 61 to contact with first of slide block 6 simultaneously, and then band movable slider 6 also does the rotation of circumferencial direction, because the cell wall 21 of tooth hub groove coordinates inclined-plane 62 to have certain angular compliance with second of slide block 6, so slide block 6 is on the gear shifting force basis that tooth cover 1 gives, increase again the axial force that a tooth hub 2 pairs of slide blocks 6 do, the synchronizing ring 3 that now slide block 6 can promote to coordinate with its grafting further moves towards engaging ring gear 4 position, thus make the tapered collar 41 engaging ring gear 4 fit tightr with the internal ring wall 32 of synchronizing ring 3, so increase frictional force between the two, so then further reduce the time that synchronizing ring 3 is synchronized with engaging ring gear 4.
The design of this synchronizer, while decreasing component, also improves the friction torque of parts, and then improves synchronous efficiency, decreases cost of production simultaneously.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
