Abstract
The invention relates to a fixed stroke synchronizer in the technical field of automotive engineering, comprising conjunction gears, synchronizer rings, a gear hub, a gear sleeve, an integrated moduleand a positioning device. The integrated module is arranged on the outer edge of the gear hub and clamped on the gear sleeve; the positioning device is arranged on the inner edge of the gear sleeve which is sleeved on the gear hub; and the two synchronizer rings and the two conjunction gears in the same structures are sequentially sleeved at both sides of the gear sleeve from interior to exteriorin a mirrorsymmetry mode. The synchronizer with the anti-extrusion integrated module simplifies the structure, eliminates shifting failures, even synchronizer failures due to the extrusion of a steelball of the integrated module out of the gear sleeve while shifting and effectively lowers noise generated during shifting.

Background technique
Automobile synchronizer is that a kind of automobile that makes is realized the steadily mechanical device of gearshift.In conventional gear box (MT), in order to realize that gear shift operation is rapid, light, not have and impact, reach the power character and the fuel economy that improve automobile, adopt synchronizer to realize gear shift operation more.The structural type of synchronizer generally has constant pressure synchronizer, inertial type of synchronizer, inertia booster type synchronizer etc.Wherein inertial type of synchronizer be owing to can guarantee synchromesh gearshift, and simple in structure, is used widely at home at present.Inertial type of synchronizer can divide lock ring type inertia synchronizer, lockpin-type inertia synchronizer, lock ring type to bore inertia synchronizer etc. by structure more.
Find through retrieval prior art, Chinese invention patent application number 94112951.9, publication number CN 1123746A, put down in writing a kind of " Synchromous device of gearbox ", this technology is mainly improved the design of speed governing copper ring in the conventional synchronizer, with the intensity of increase copper ring and the capacity of synchronizer, and use helical spring to replace linear spring, to solve the problem of speed governing key discontinuity.But contact for face between the synchronizer key in the prior art and the synchronizer gear sleeve, in synchronizing process, exist transmission gearshift power steady inadequately, the defective that the not high enough noise of shift quality is excessive, spring, slide block, steel ball assemble difficulty in addition, and steel ball is deviate from when gearshift easily.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of fixed stroke synchronizer is provided, deviate from the situation generation that the tooth cover influences gearshift even synchronizer inefficacy because of the steel ball of integrated slider when having eliminated gearshift in simplified structure, the noise when shifting gears has simultaneously obtained effectively reducing.
The present invention is achieved by the following technical solutions, the present invention includes: in conjunction with tooth, synchronizing ring, tooth hub, tooth cover, integrated slider and positioning device, wherein: integrated slider is arranged at the outer of tooth hub, integrated slider and the clamping mutually of tooth cover, positioning device is arranged at the interior edge of tooth cover, tooth hub and tooth cover socket-connect, the synchronizing ring of two groups of same structures and in conjunction with tooth successively from inside to outside minute surface be socketed in the both sides of tooth cover symmetrically.
It is interior along uniform some steel ball grooves that described tooth overlaps, and described integrated slider is connected in the steel ball groove of tooth cover.
Uniform some slide block slots on the described tooth hub, described integrated slider is installed in the slide block slot of tooth hub.
Described integrated slider is provided with steel ball and fixture block, and wherein: fixture block is the cuboid structure, and fixture block parallels with the slip surface of integrated slider and contacts with slide block slot, steel ball be flush-mounted in the integrated slider and with the steel ball groove clamping of tooth cover.
Described slide block slot is provided with locating button, and this locating button and fixture block are complementary.
Described positioning device is rectangular configuration and the interior edge that is fixedly set in the tooth cover, and the number of this positioning device is identical with the number of integrated slider and the position is staggered.
Described tooth hub is provided with locating notch, and the position of this locating notch and the position of positioning device are complementary so that positioning device slides therein, and this locating notch and slide block slot are arranged alternately on the tooth hub.
The hypodontia space is arranged on the described synchronizing ring, and the position of this hypodontia space is corresponding with positioning device, and positioning device can be passed through when gearshift.
The interior edge of the outer of described tooth hub and tooth cover is respectively equipped with the spline of some mutual couplings, and tooth hub and tooth cover are installed by spline fitted.
Described tooth hub is provided with some synchronous corner grooves, and this synchronous corner groove is corresponding with the synchronous corner boss of synchronizing ring.
The present invention carries out work in the following manner: when shift fork is stirred the tooth cover, moving from neutral gear position vertically to the targeted gear displacement, driving integrated slider and positioning device simultaneously moves together in the same way, by integrated slider end face bump synchronizing ring side, synchronizing ring is pressed in conjunction with the tooth conical surface, because in conjunction with tooth, synchronizing ring and tooth hub have speed difference, this moment is in conjunction with the relative tooth hub motion of the moving synchronizing ring of cingulum, when the tooth hub with in conjunction with the rotating speed of tooth when identical, the tooth cover drives integrated slider and positioning device continues to move, deviate from the steel ball groove of tooth cover until the steel ball of integrated slider, then the tooth cover contacts and produces ring moment with synchronizing ring, this ring moment promote synchronous loopback just and with separate in conjunction with tooth, the tooth cover passes through spline engagement with synchronizing ring then, the tooth cover continues be with positioning device to move, and bumps against in conjunction with flank until positioning device with combining the tooth engagement, finishes gearshift.
Compare with existing structure, the present invention has effectively limited integrated slider with respect to the stroke that tooth overlaps, and has avoided like this when gearshift, because of the steel ball of integrated slider is deviate from the situation generation that the tooth cover influences gearshift even synchronizer inefficacy.
