Description
Technical field
The utility model relates to a kind of synchronizer structure, particularly a kind of three conical surface synchronizers that are used for manual transmission.Belong to the automotive trannsmission system field.
Background technique
In recent years, adopted single conical surface manual transmission in the automotive transmission at home and abroad mostly.This speed changer is more painstaking when changing a second gear, the gear shift irregularity, and driver's labor intensity is bigger; Some driver's gear shift timing is improper in addition, and such as just reduce to one grade or second gear when the speed of a motor vehicle is too high, it is particularly evident at this moment to hang the phenomenon not advance shelves.Speed changer manufacturer has carried out effort aspect improving the quality, but produces little effect.In fact, the not good basic reason of one, two gear shift net synchronization capabilities is that a traditional second gear synchronizer is single conical surface form.As synchronizer, its performance index are: the synchronising torque under the identical berth-changing strength, lock in time, the former is the bigger the better, and the latter is short more good more, and the two is to be mutually related.The direct factor that influences these two performance index has: the diameter of synchronizing ring, area of contact, friction factor.Generally speaking, friction factor is subjected to the restriction of material property, is difficult for improving again; The diameter of synchronizing ring then is subjected to the restriction in speed changer space, and room for improvement is limited, only seeks the breach on structural type.And single conical surface manual transmission is controlled by structure space, and less than normal by single synchronous friction torque that fastness is produced, shift time is long, the tooth cover with combine tooth and easily impact, working life weak point.
Through patent retrieval, find that Chinese patent application number is: 0120043.0, the model utility that name is called " twin cone lock ring synchronizer is arranged " relates to the transformation to single conical surface manual transmission, and it is to adopt biconical surface structure, but shift time is still long partially, and the gear shift dynamics is still bigger than normal.
Summary of the invention
The purpose of this utility model be to overcome change one in the prior art, relatively more painstaking during second gear, hang deficiency that not advance shelves, a kind of three conical surface synchronizers are provided, make synchronising torque strengthen greatly, thereby shortened lock in time, widen the operating range of synchronizer, under the prerequisite that does not change former transmission dimensions, can effectively improve net synchronization capability, alleviate berth-changing strength greatly, reduce driver's labor intensity, improve the car load travelling comfort.
The utility model is achieved through the following technical solutions, the utility model comprises: intermediate gear, interior conical ring, outer conical ring, central ring, synchronizer spring, the tooth cover, the tooth hub, slide block, one grade of gear, first groove, slide block slot, second groove, its annexation is: interior conical ring, central ring, outer conical ring from inside to outside set gradually the friction ring that constitutes on the gear, the inner cone annular space is enclosed within on the gear conical surface, middle annular space is enclosed within on the interior conical ring, the outer cone annular space is enclosed within on the central ring, central ring is by groove and intermediate gear on the gear tooth, one grade of gear connects, tooth cover inwall has slide block slot, whole slide block is embedded in the tooth hub groove, two synchronizer springs are close to tooth hub both sides respectively, and outer conical ring large end face place is provided with groove.
The inner cone annular space is enclosed within on the gear conical surface, and interior conical ring has the hook pin, and inner cone bail pin is stretched in the groove at conical ring large end face place outside so that and outer conical ring rotate synchronously; On the conical ring, central ring had protruding pin in middle annular space was enclosed within, and the protruding pin of central ring is embedded in the groove of gear face, so that rotate synchronously with gear.
Tooth has put internal spline, on the tooth hub external splines is arranged, the tooth cover by spline housing on the tooth hub; Synchronizer spring withstands on slider top in the slide block slot of tooth cover inwall all the time.
The tooth hub is close to gear face and is fixedly connected on the axle, and when slide block was withstood in the slide block slot by synchronizer spring, the slide block outer end was embedded in the groove at outer conical ring small end place.
One, second gear three conical surface synchronizers are stirred the tooth cover by shift fork and are realized that one grade of gear or intermediate gear are synchronous.Tooth cover drives slide block, and slide block promotes outer conical ring, and central ring and shifting gear pass through the interconnected maintenance run-in synchronism of tooth embedding structure, outside under the active force of conical ring, and outer conical ring and central ring; Interior conical ring and central ring; Form three friction pairs between the interior conical ring and the shifting gear conical surface.The synchronising torque of three friction pair formation makes the tooth cover synchronous rapidly with shifting gear.Synchronously, friction torque disappears, and the tooth cover is crossed outer conical ring and combined with gear, finishes whole synchronizing process.
In the synchronizing process of the utility model structure, these three pairs of conical surfaces of the interior conical ring and the shifting gear conical surface, central ring and interior conical ring, central ring and outer conical ring will be worked simultaneously, increase the friction torque of gear synchronizing process, friction torque reaches three times of former single conical surface synchronizer nearly, can increase synchronising torque effectively thus, thereby reduce berth-changing strength and reduce lock in time, and make gearshift procedure steady, net synchronization capability improves greatly.
