Below with reference to Fig. 1-Fig. 9, describe according to the synchronizer assembly 1 for speed changer of the embodiment of the present invention.As shown in Fig. 1-Fig. 9, according to the synchronizer assembly 1 for speed changer of the embodiment of the present invention, comprise: transmission shaft 10, gear 20, splined hub 30, clutch collar 40 and synchronizing ring 50.
Splined hub 30 is enclosed within on transmission shaft 10, and splined hub 30 is rotated with transmission shaft 10.Splined hub 30 is positioned at a side of gear 20.Clutch collar 40 is enclosed within splined hub 30 outsides, and clutch collar 40 can be along the moving axially of transmission shaft 10 with respect to splined hub 30, and clutch collar 40 rotates with splined hub 30.On clutch collar 40, be configured with clutch collar fitting surface 401, and clutch collar 40 is also provided with and the internal spline 410 that engages gear ring 210 adaptations.As shown in Figure 1, on the outer circumferential face of splined hub 30, can be provided with the external splines 310 with internal spline 410 adaptations.Synchronizing ring 50 is rotated with gear 20.In synchronizing ring 50, be configured with synchronizing ring fitting surface 501, synchronizing ring 50 is provided with synchronizing ring projection 510.
Wherein, clutch collar 40 can move with respect to engaging gear ring 210 between neutral gear position and engagement positio, at clutch collar 40 during in described neutral gear position, clutch collar fitting surface 401 with synchronizing ring fitting surface 501 in separated state; At clutch collar 40, during in described engagement positio, clutch collar fitting surface 401 engages gear rings 210 with synchronizing ring fitting surface 501 in impaction state and internal spline 410.At clutch collar 40, from described neutral gear position to described engagement positio between moving period, elasticity thrust piece 220 is suitable for against synchronizing ring projection 510 so that clutch collar fitting surface 401 is converted to described impaction state with synchronizing ring fitting surface 501 from described separated state.
Alternatively, synchronizing ring fitting surface 501 and clutch collar fitting surface 401 can be all the conical surface.As shown in Fig. 7-Fig. 9, synchronizing ring fitting surface 501 is male cone (strobilus masculinus), and correspondingly clutch collar fitting surface 401 is inner conical surface.Synchronizing ring fitting surface 501 is outward-dipping gradually to the one end away from splined hub 30 from the one end near splined hub 30, and clutch collar fitting surface 401 slopes inwardly to the one end away from splined hub 30 gradually from the one end near splined hub 30.Wherein, in the direction of transmission shaft 10 is, outside the direction that deviates from transmission shaft 10 is.That is to say, splined hub 30 is turned up the soil and is for example arranged in transmission shaft 10(along the axially spaced-apart of transmission shaft 10, the output shaft of speed changer with gear 20).The shift fork of the operating mechanism of speed changer is stirred clutch collar 40 and axially between described neutral gear position and described engagement positio, is moved along described with respect to engaging gear ring 210.
As shown in Figure 7, at clutch collar 40 during in described neutral gear position, speed changer is in neutral position state, and the internal spline 410 of clutch collar 40 do not engage with engaging gear ring 210, and clutch collar 40 and gear 20 are respectively with speed rotation separately.Particularly, synchronizing ring 50 is rotated with gear 20, and gear 20 is connected with the driven disc of clutch by transmitting assemblies, and the rotating speed of gear 20 and the rotating speed of driven disc are directly proportional.Clutch collar 40 is connected with transmission shaft 10 by splined hub 30 and rotates with transmission shaft 10, and transmission shaft 10 keeps drive connection by transmission device and vehicle, and the rotating speed of clutch collar 40 is directly proportional to the travelling speed of vehicle.
As shown in Figure 9, at clutch collar 40, during in described engagement positio, the internal spline 410 of clutch collar 40 engages with engaging gear ring 210, and clutch collar 40 is synchronizeed rotation with gear 20, speed changer in the corresponding gear of gear 20.
Take below gear 20 as six gear gears be example, when describing speed changer and hanging into six gears from neutral, for the working procedure of the synchronizer assembly 1 of speed changer:
Shift fork is stirred clutch collar 40, and clutch collar 40 is moved to gear 20 vertically, and it is close to engaging gear ring 210 that clutch collar 40 promotes synchronizing ring 50 by clutch collar fitting surface 401 and coordinating of synchronizing ring fitting surface 501.Continue to stir clutch collar 40, elasticity thrust piece 220 makes clutch collar fitting surface 401 and synchronizing ring fitting surface 501 be converted to described impaction state from described separated state against synchronizing ring projection 510.
Particularly, synchronizing ring 50, under the drive of clutch collar 40, makes synchronizing ring projection 510 contact (as shown in Figure 8) with elasticity thrust piece 220.Now, it is close to engaging gear ring 210 that elasticity thrust piece 220 stops synchronizing ring 50 continuation., impose under the effect of axial force of synchronizing ring 50 at clutch collar 40, clutch collar fitting surface 401 produces friction torque with synchronizing ring fitting surface 501, realizes presynchronization meanwhile.
Continue to promote clutch collar 40, under the effect of axial force, synchronizing ring projection 510 overcomes the resistance of elasticity thrust piece 220, makes synchronizing ring 50 continue to move to engaging gear ring 210, and clutch collar fitting surface 401 is realized and being synchronizeed gradually under the effect of friction torque with synchronizing ring fitting surface 501.The internal spline 410 and the joint that engages gear ring 210 of final clutch collar 40, gear 20 is synchronizeed rotation with clutch collar 40, and speed changer is hung into six gears.
That is to say, for the synchronizer assembly 1 of speed changer, by clutch collar fitting surface 401, realize and synchronizeing with the rubbing action of synchronizing ring fitting surface 501.Therefore, according to the synchronizer assembly 1 for speed changer of the embodiment of the present invention, under the prerequisite of volume that does not increase synchronizer assembly 1, increased friction radius, thereby increased friction torque, the synchronous speed of synchronizer assembly 1 is improved, improved the synchronizing capacity of synchronizer assembly 1.
Alternatively, as shown in Fig. 1, Fig. 7-Fig. 9, elasticity thrust piece 220 can be jump ring.Further, as shown in Figure 2 and Figure 4, on gear 20, can be provided with jump-ring slot 201, jump ring can be for arc and clip be in jump-ring slot 201.
As shown in Figure 2, engage on gear ring 210 and can be provided with guiding groove 211, it is interior so that synchronizing ring 50 is rotated with gear 20 that synchronizing ring projection 510 can be engaged in guiding groove 211, and synchronizing ring projection 510 can move axially described in the interior edge of guiding groove 211.One end of guiding groove 211 is towards splined hub 30 extensions and exceed jump ring.Not only can there be certain position-limiting action one end that exceeds jump ring of guiding groove 211 to jump ring, and synchronizing ring projection 510 is engaged in guiding groove 211 always.
Advantageously, in one embodiment of the invention, guiding groove 211 can be for a plurality of, and a plurality of guiding grooves 211 engage on gear ring 210 along engaging being circumferentially evenly distributed on of gear ring 210, synchronizing ring projection 510 can be for a plurality of, and a plurality of synchronizing ring projection 510 is distinguished corresponding one by one with a plurality of guiding grooves 211.
In other words, the number of the number of guiding groove 211 and synchronizing ring projection 510 equates, and a synchronizing ring projection 510 is engaged in a guiding groove 211.Thus, synchronizing ring 50 coordinates more stable with gear 20.As shown in Figure 3 and Figure 5, in a concrete example of the present invention, synchronizing ring projection 510 is three, and guiding groove 211 is three.
As shown in Fig. 1, Fig. 7-Fig. 9, in one embodiment of the invention, on the outer circumferential face of splined hub 30, be provided with location blind hole 320, the inner peripheral surface of clutch collar 40 is provided with positioning groove 420.Correspondingly, the synchronizer assembly 1 for speed changer can also comprise steel ball 60 and spring 70.Steel ball 60 and spring 70 are located in the blind hole 320 of location, and spring 70 flexibly pushes against steel ball 60 so that a part for steel ball 60 is stretched out outside location blind hole 320 and is resisted against in positioning groove 420.Thus, can clutch collar 40 during in described neutral gear position to clutch collar 40 location, prevent that clutch collar 40 from rocking.
Here it will be appreciated that, steel ball 60 is not to be engaged in positioning groove 420 always, and along with clutch collar 40 moves to described engagement positio from described neutral gear position, steel ball 60 can be deviate from positioning groove 420 gradually.Because synchronizing ring 50 and gear 20 all do not come in contact with splined hub 30, the swing of synchronizing ring 50 and gear 20 can not impacted splined hub 30, steel ball 60 can not deviate from the constraint of clutch collar 40 and splined hub 30 yet, thereby can avoid steel ball 60 to deviate from constraint and cause speed changer cannot get back to the phenomenon of neutral gear, thereby making the performance of synchronizer assembly 1 more stable.
On the inner peripheral surface of synchronizing ring 50, be provided with synchronous gear 520, on synchronous gear 520, be configured with synchronous gear locking face 521, on the tooth of joint gear ring 210, be configured with the gear ring locking face 212 that engages with synchronous gear locking face 521 adaptations.By synchronous gear locking face 521 being set and engaging gear ring locking face 212, in the time of can preventing that clutch collar 40 from not synchronizeing with gear 20, the internal spline 410 of clutch collar 40 engages with engaging gear ring 210, thereby makes the synchronizing process of synchronizer assembly 1 more steady, namely makes the shift process of speed changer more steady.
Further, the synchronizer assembly 1 for speed changer can also comprise baffle plate 80.Baffle plate 80 can be fixed on clutch collar 40, baffle plate 80 be suitable for clutch collar 40 from described engagement positio to described neutral gear position movement process backstop synchronizing ring 50.
When baffle plate 80 under the drive of clutch collar 40 with clutch collar 40 from described engagement positio to described neutral gear position movement process, clutch collar fitting surface 401 changes separated state with synchronizing ring fitting surface 501 into gradually from impaction state, baffle plate 80 can backstop synchronizing ring 50, prevents that synchronizing ring 50 can not return.
At one alternatively in embodiment of the present invention, the cross section of baffle plate 80 can be U-shaped.Wherein, when clutch collar 40 is during in described engagement positio, a sidewall of baffle plate 80 can only support gear 20.When clutch collar 40 from described engagement positio to described neutral gear position movement process, the described sidewall of baffle plate 80 can backstop synchronizing ring 50.In a concrete example of the present invention, baffle plate 80 can be riveted and is fixed on clutch collar 40.
Below with reference to the structure in embodiment above, and describe the working procedure for the synchronizer assembly 1 of speed changer in detail with reference to Fig. 7-Fig. 9:
In description below, still take gear 20 as six gear gears 20 be example.
First describe, for the synchronizer assembly 1 of speed changer, from the neutral gear position shown in Fig. 7, move to the process of the presynchronization position shown in Fig. 8:
Shift fork is stirred clutch collar 40 and is moved to gear 20, and it is close to engaging gear ring 210 that clutch collar 40 promotes synchronizing ring 50 by clutch collar fitting surface 401 and the cone match of synchronizing ring fitting surface 501.Continue to stir clutch collar 40, synchronizing ring projection 510 contacts with jump ring, it is close that jump ring stops synchronizing ring 50 to continue to engaging gear ring 210, at clutch collar 40, impose under the effect of axial force of synchronizing ring 50, clutch collar fitting surface 401 produces friction torque with synchronizing ring fitting surface 501, and a sidewall contact of synchronizing ring projection 510 and guiding groove 211, now on axial position, synchronous gear locking face 521 is relative with joint gear ring locking face 212, realizes presynchronization.In this process, steel ball 60 is also deviate from gradually from positioning groove 420.
The synchronizer assembly 1 the following describes for speed changer moves to the process of the engagement positio shown in Fig. 9 from the presynchronization position shown in Fig. 8:
Continue again to promote clutch collar 40, the prevention that synchronizing ring projection 510 overcomes elasticity thrust piece 220 continues to move to engaging gear ring 210, synchronous gear locking face 521 contacts locking with engaging gear ring locking face 212, until clutch collar fitting surface 401 is realized and being synchronizeed gradually under the effect of friction torque with synchronizing ring fitting surface 501.After synchronously completing, the internal spline 410 of synchronous gear 520 and clutch collar 40 all engages with engaging gear ring 210, and baffle plate 80 only supports gear 20, realizes the rotation of synchronizeing of gear 20 and clutch collar 40, and speed changer is hung into six gears.
When getting back to neutral gear from six gears, clutch collar 40 drives baffle plate 80, and baffle plate 80 drives synchronizing ring 50 to move to the direction away from engaging gear ring 210, until synchronizing ring 50 and clutch collar 40 are all got back to described neutral gear position.
