Description
Technical field
The utility model relates to automobile technical field, especially relates to a kind of synchromesh gear.
Background technique
Synchronizer (Synchronizer) is that the gear that speed changer is bonded with each other in gearshift is realized synchronous device.
In shift process, should make the peripheral velocity of the joint gear ring of that a pair of gear of preparing engagement reach equal (namely synchronous), could smoothly hang up gear.Otherwise, can send between two gear-wheel gear-rings and impact and noise, affect the life-span of gear.For the ease of shifting gears, the Hyundai Motor speed changer all is equipped with synchronizer between each gear commonly used, makes a pair of gear that is meshed synchronous first, then engagement.
Synchronizer has gerotor type and inertia-type.What extensively adopt at present is inertia synchronizer, and it mainly is comprised of clutch collar, lock ring, slide block and lock pin etc., and as shown in Figure 1, its feature is to rely on rubbing action to realize synchronously.
On the gear ring of clutch collar, synchronous lock ring and gear to be joined chamfering (angle of lock) is arranged all, the inner conical surface of lock ring contacts with gear-wheel gear-ring male cone (strobilus masculinus) to be joined and produces friction synchronously.Angle of lock and the conical surface have been done suitable selection when design, conical surface friction can produce again a kind of locking effect simultaneously so that tooth cover to be engaged is synchronous rapidly with gear ring, prevents that gear from meshing at the advanced in unison row.
When synchronous lock ring inner conical surface with after gear-wheel gear-ring male cone (strobilus masculinus) to be joined contacts, effect lower gear rotating speed in friction torque reduces rapidly (or rising) to equating with synchronous lock ring rotating speed, both synchronous rotaries, gear is zero with respect to the rotating speed of synchronous lock ring, thereby moment of inertia also disappears simultaneously, at this moment under the promotion of active force, clutch collar engages with the synchrolock annular gear in the clear, and further engages with the gear ring of gear to be joined and finish shift process.
Because low cost and the high reliability of synchronizer are applied to mechanical gearbox, MT, AT and DCT widely.The engagement process of synchronizer is to adopt friction type to realize, carry-over moment be always need to consider in the design parameter, how shortening the gearshift time simultaneously all is important design goal for car load power character and travelling comfort.The conical surface of synchronizer and the design of chamfering moment need to contain maximum possible resisting moment, and the high viscosity during such as cold start-up can significantly increase resisting moment, shortens engagement time simultaneously, and particularly when the high speed discrepancy of low gear, can increase engagement time.The most direct solution is to adopt multi-cone synchronizer, but can increase the synchronizer axial length, has limited its extensive utilization.
The model utility content
The technical problem that the utility model solves is to provide the synchronizer that a kind of lock in time is short, the synchronizing process resisting moment is little.
In order to overcome the above problems, the utility model provides a kind of synchromesh gear, comprise: lock pin, combined cover, lock ring, slide block, the lock ring male cone (strobilus masculinus) is designed to rubbing surface and Gear Contact, internal spline chamfering and the engagement of the combined cover outside, the internal spline inboard is by spline and gear shaft engagement, and lock pin is used for combined cover and the rear locking of target gear spline engagement, and slide block slides in the inboard chute of combined cover.
Further, as preferably, described lock pin, combined cover, lock ring, slide block are between power shift gear.
Owing to changing the structure of lock ring, male cone (strobilus masculinus) is designed to rubbing surface and Gear Contact, adopt the engagement of internal spline and combined cover.Can increase maximum friction moment, can optimize chamfering moment by suitable chamfer design, therefore can obtain larger conical surface radius, to reduce lock in time, by increasing conical surface moment, reduce combined cover displacement distance, so that the gearshift response is rapider.In addition, a significant design of transmission design is sealing, synchronizer and power shift gear have increased gear shaft length, this model utility can significantly reduce axial length, and synchronizer is placed on below the power shift gear, increased the mobile space of combined cover and shift fork, main mechanical part concentrates on below the gear, so that sealing is better.
Description of drawings
When considered in conjunction with the accompanying drawings, by the following detailed description of reference, can more completely understand better the utility model and easily learn wherein many advantages of following, accompanying drawing described herein is used to provide further understanding of the present utility model, consist of a part of the present utility model, illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of to improper restriction of the present utility model, wherein:
Fig. 1 has synchronizer structure figure now;
Fig. 2 is the utility model synchronizer example structure figure;
Fig. 3 is gearshift synchronizing process schematic diagram.
Embodiment
Referring to figure embodiment of the present utility model is described.
For above-mentioned purpose, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 2, a kind of synchromesh gear, comprise: lock pin 1, combined cover 2, lock ring 3, slide block 6, lock ring 3 male cone (strobilus masculinus)s are designed to rubbing surface and contact with gear 4, internal spline chamfering 5 and the engagement of combined cover 2 outsides, the internal spline inboard is by the engagement of spline and gear shaft, and lock pin 1 is used for locking after combined cover 2 and target gear 4 spline engagement, and slide block 6 slides in combined cover 2 inboard chutes.
Change the structure of former lock ring, male cone (strobilus masculinus) is designed to rubbing surface and Gear Contact, adopt the engagement of internal spline and combined cover.Can increase maximum friction moment, can optimize chamfering moment by suitable chamfer design, therefore can obtain larger conical surface radius, to reduce lock in time, by increasing conical surface moment, reduce combined cover displacement distance, so that the gearshift response is rapider.
A significant design of transmission design is sealing, synchronizer and power shift gear have increased gear shaft length, this model utility can significantly reduce axial length, and synchronizer is placed on below the power shift gear, increased the mobile space of combined cover and shift fork, main mechanical part concentrates on below the gear, so that sealing is better.
Show combined cover and the slide block position in engagement process such as Fig. 3, (a) be the neutral position, (b) for combined cover moves forward the contact lock ring, be that lock ring is recalled when combined cover and lock ring engagement (c), (d) be lock pin locking after combined cover and the engagement of target gear spline.
As mentioned above, embodiment of the present utility model is explained, but as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the present utility model.
