Technical field
The present invention relates to a kind of speed changer synchronizer, belong to the drive technology field of automobile.
Background technique
In recent years, in automotive transmission, mostly adopt lock ring type synchronizer at home and abroad, but the narrow limitation due to speed changer structure, space, make the lifting of synchronizer performance have problems, there is single cone synchronizer to develop into Double-conical-surface, multi-cone synchronizer, complicated along with structure, synchronizer manufacture cost increases thereupon.Driver generally proposes higher requirement to shift quality, and speed changer constantly increases the demand of large capacity synchronizer.
Summary of the invention
The problem to be solved in the present invention is to provide the speed changer synchronizer that a kind of time of shifting gears is short, gear shifting force is little, conical surface gearshift moment is high, simple in structure, cost is low.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of speed changer synchronizer is provided, comprise tooth cover, toothholder, synchronizing ring, cone, slide block and spring, tooth cover engage sleeves is contained on toothholder, the bottom of slide block is inlaid in the set groove of toothholder periphery, the top of slide block is inlaid in tooth and overlaps in set slide block slot and can endwisely slip, mounting spring between slide block and toothholder, synchronizing ring is provided with inner conical surface, synchronizing ring is sleeved on the male cone (strobilus masculinus) of cone, described slide block is " saddle " shape structure, comprise two projections and a connecting body, the outside end face of projection is provided with slide block reinforcement angle, the inner side end of projection is provided with slide block angle of lock, the upper-end surface of connecting body is provided with slider support angle, two inner side surfaces that are used for installing the groove of slide block on described toothholder are provided with and the toothholder reinforcement angle that contact is connected of matching, slide block reinforcement angle, and the excircle of described synchronizing ring is provided with slide block angle of lock and matches and contact the synchronizing ring angle of lock being connected.
In shift process, synchronizing ring and the cone conical surface produce moment conical surface moment of torsion, and toothholder and synchronizing ring are produced relative rotation, relatively rotate generation peripheral force, peripheral force acts on slide block, under the effect of toothholder reinforcement angle, produces axial thrust load, secondary compression synchronizing ring, produces synchronous reinforcement; Peripheral force contact slipper angle of lock under the effect of synchronizing ring angle of lock forms locking, guarantees that synchronously nipper cover can not crossed slide block.
Further, two formed angles of slide block angle of lock of described slide block are downward opening dovetail shaped, and two formed angles of synchronizing ring angle of lock in described synchronizing ring are opening up dovetail shaped.
Further, two of described slide block formed angles in slide block reinforcement angle and connecting body exterior edge face are not less than 90 °.
Further, described synchronizing ring does not have external tooth.
Advantage and good effect that the present invention has are: the present invention has improved gearshift performance greatly, effectively shortened the gearshift time, reduced gear shifting force, improved conical surface gearshift moment, and have simple in structure, the advantage of low cost of manufacture.

Embodiment
For to the more deep understanding of the present invention, enumerate a specific embodiment below, and by reference to the accompanying drawings, the present invention is described in further detail.
In traditional manual synchronizer, tooth cover and synchronizing ring locking tooth contact, promote synchronizing ring and contact the whole synchronous torques of formation with cone rubbing surface, and the axial force producing passes to driver by gearshift, and this mechanism is helpless to reduce gear shift operation power.
The present embodiment is a kind ofly can complete fast by less gear shift operation power the speed changer synchronizer of gearshift, as shown in Figure 1, comprise tooth cover 1, toothholder 2, synchronizing ring 3, cone 4, slide block 6 and spring 5, tooth overlaps 1 engage sleeves and is contained on toothholder 2, the bottom of slide block 6 is inlaid in the set groove of toothholder 2 peripheries, the top of slide block 6 is inlaid in tooth and overlaps in 1 set slide block slot 11 and can endwisely slip, 2 mounting spring 5 of slide block 6 and toothholder, synchronizing ring 3 is provided with inner conical surface, and synchronizing ring 3 is sleeved on the male cone (strobilus masculinus) of cone 4; Slide block 6 is " saddle " shape structure, as shown in Figure 2, comprise two projections 64 and a connecting body 65, the outside end face of projection 64 is provided with slide block reinforcement angle 62, the inner side end of projection 64 is provided with slide block angle of lock 63, and the upper-end surface of connecting body 65 is provided with slider support angle 61; Two sides that are used for installing the groove of slide block 6 on toothholder 2 are provided with and the toothholder reinforcement angle 21 that contact is connected of matching, slide block reinforcement angle 62, as shown in Figure 3, the excircle of synchronizing ring 3 is provided with slide block angle of lock 63 and matches and contact the synchronizing ring angle of lock 31 being connected, as shown in Figure 4.
In the present embodiment, two formed angles of slide block angle of lock 63 of slide block 6 are downward opening dovetail shaped, and two formed angles of synchronizing ring angle of lock 31 in synchronizing ring 3 are opening up dovetail shaped, corresponding with slide block angle of lock 63.
In the present embodiment, two slide block reinforcement angles 62 and the connecting body 65 formed angles in exterior edge face of slide block are not less than 90 °; Synchronizing ring 3 does not have external tooth.
In shift process, tooth cover 1 produces end thrust under selector fork effect, by tooth, put slide block slot 11 and act on slide block 6, slide block 6 produces axial motion under spring 5 support reaction effects, promote synchronizing ring 3 axial motions, because rubbing action between synchronizing ring 3 inner conical surfaces and the male cone (strobilus masculinus) of cone 4 produces instantaneous synchronous torque, synchronizing ring 3 and toothholder 2 are produced relative rotation, now, slide block reinforcement angle 62 contacts the rotation of stop synchronizing ring with toothholder reinforcement angle 21, produce axial thrust load and compress synchronizing ring 3, together with gear shifting force acting in conjunction in synchronizing ring 3, slide block angle of lock 63 contacts with synchronizing ring angle of lock 31 and forms locking under synchronizing ring torsional interaction simultaneously, guarantee that synchronous nipper cover can not cross slide block 6, after synchronizing process completes, along with angular velocity difference disappears, conical surface moment of torsion reduces, and tooth cover slide block slot 11 presses down slider support angle 61, makes slide block 6 descending, tooth cover 1 and cone 4 combinations, and gearshift completes.
Above embodiments of the invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the scope of the invention and improvement etc., within all should still belonging to this patent covering scope.
