To more specifically quote the preferred embodiments of the invention below, one of them example shows in the accompanying drawings.In possible situation, run through reference character identical in drawing and description and will be used in reference to same or similar parts.
Fig. 2 is the view that shows the structure of the state of the synchronizer for speed changer according to the present invention before its synchromesh; Fig. 3 is the view that shows the structure of the state of the synchronizer for speed changer according to the present invention after its synchromesh; And Fig. 4 is the view that is formed on the shape of the power shift gear 31 on the inner circumference of the sleeve 30 in synchronizer, and wherein the gear teeth of power shift gear have different thickness;
Referring to figs. 2 to 4, the synchronizer for speed changer according to the present invention generally comprises sleeve 30, synchronous key 40, balk ring 50 and transmission gear 60.
Particularly, sleeve 30 rotatably arranges around wheel hub 20, and this wheel hub 20 is attached to gear shaft 10, thereby makes sleeve removable on the axial direction of gear shaft 10.Sleeve has power shift gear 31 on circumference therein.Thereby it is outstanding towards sleeve 30 that synchronous key 40 is set to wheel hub 20, and one end of synchronous key 40 is supported by power shift gear 31.Balk ring 50 is arranged around the circumference of wheel hub 20.Transmission gear 60 can rotate freely and be arranged in around balk ring 50, and edge circumferentially has clutch gear 61 in the direction towards sleeve 30.In the time that sleeve 30 moves, power shift gear 31 engages rightly with clutch gear 61.
Here, synchronous key 40 is provided with tension spring 41, and it is flexibly arranged in wheel hub 20 to oppress synchronous keys 40 towards sleeve 30 elasticity.
Balk ring 50 has the first tapered contact surface 52, transmission gear 60 has the second tapered contact surface 62 with described the first tapered contact surface 52 rubbing contact, make when the first and second contact surfaces 52 and 62 are each other when rubbing contact, balk ring and transmission gear are by synchronous.
That is to say, in the time of operation transmission operating handle, sleeve 30 is pushed towards transmission gear 60, forms each other rubbing contact with the first contact surface 52 that allows balk ring 50 with the second contact surface 62 of transmission gear 60 by means of synchronous key 40, starts synchronization motion.Here, because balk ring 50 rotates together with sleeve 30, and transmission gear 60 has different circumference RPM, therefore during rotation first skids.But, along with the carrying out of synchronization motion, skid and alleviate gradually and realized synchronous completely.
Then, complete sleeve 30 and transmission gear 60 has identical RPM once synchronizing, 30, sleeve is further pushed towards transmission gear 60, thereby the power shift gear 31 that makes to be formed on sleeve 30 engages with the clutch gear 61 of transmission gear 60.Thus, be passed to output shaft via paired transmission gear 60 from the power of motor transmission.
As at length shown in Fig. 3, power shift gear 31 is according to having the first and second gear teeth thickness L1 and L2 with respect to the contact condition of synchronous key 40.First round transverse tooth thickness degree L1 can be that power shift gear 31 forms with synchronous key 40 thickness contacting, do not form with synchronous key 40 thickness contacting and the second gear teeth thickness L2 can be power shift gear 31, wherein said first round transverse tooth thickness degree is preferably greater than described the second gear teeth thickness.
Particularly, power shift gear 31 and synchronous key 40 form the first round transverse tooth thickness degree L1 contacting and can be greater than power shift gear 31 and do not form 1.5 times of the second gear teeth thickness L2 contacting with synchronous key 40.
That is to say, power shift gear 31 and synchronous key 40 form the first round transverse tooth thickness degree L1 contacting and are formed as being greater than power shift gear 31 and do not form with synchronous key 40 the second gear teeth thickness L2 contacting, (, the conventional gear teeth thickness using), thereby make relatively to increase with respect to the contact surface of synchronous key 40, disperse thus and reduce to be applied to power shift gear and form with synchronous key 40 the lip-deep pressure contacting.Therefore, the durability of power shift gear 31 and the synchronous key 40 that contacts with power shift gear 31 is all increased.
In the present invention, power shift gear 31 can be constructed so that the opposed end that forms the power shift gear 31 contacting with synchronous key 40 is cut, thereby do not engage with clutch gear 61, make not form with synchronous key 40 power shift gear 31 contacting and engage with clutch gear 61.
Here, the power shift gear 31 contacting with synchronous key 40 has the gear teeth thickness L1 thickening, have stop surface 33, this stop surface 33 forms such shape simultaneously: the opposed end of power shift gear is cut to realize locking function, and this locking function will hereinafter be described.Thus, while there is synchromesh when the movement according to sleeve 30, forming with synchronous key 40 power shift gear 31 contacting can not engage with clutch gear 61.
In addition, in the present invention, not forming with synchronous key 40 power shift gear 31 contacting can engage with clutch gear 61.Here this power shift gear 31 certain gear teeth thickness that can be formed as attenuation.
Particularly, not forming with synchronous key 40 power shift gear 31 contacting engages with clutch gear 61, and in this structure, the gear teeth thickness L1 of the power shift gear 31 engaging with clutch gear 61 is formed as having 50% to 90% the gear teeth thickness corresponding to the gear teeth thickness L3 of clutch gear 61.
Fig. 5 shows to depend on the view that the stroke of the sleeve reducing 30 of the gear teeth thickness of the power shift gear 31 engaging with clutch gear 61 is reduced.
The operation that the stroke of sleeve 30 reduces is described with reference to Fig. 5.Here, it should be noted that the size that used only easily understands the present invention with helping people here, therefore the present invention is not limited to this.
The gear teeth thickness of power shift gear 31 be formed as thinner before, in the time that power shift gear 31 engages with clutch gear 61, length of action (a) between the gear teeth of power shift gear 31 and clutch gear 61 remains on 2mm, and the stroke that sleeve 30 moves is simultaneously 8.8mm.
On the contrary, at power shift gear 31 a certain amount of by cutting (being denoted as the broken line departing from), attenuation, in the time that power shift gear 31 engages with clutch gear, the length of action (b) between power shift gear 31 and the gear teeth of clutch gear 61 is increased to 2.34mm.But because the length of action between power shift gear 31 and clutch gear 61 should still be fixed as 2mm, therefore that increment has occurred is 0.34mm to length of action is more than needed.
Like this, the shift motion of sleeve 30 has reduced the increment of 0.34mm, and therefore the stroke S2 of sleeve 30 is decreased to 8.46mm, and it is than the little 0.34mm of the original stroke of sleeve 30 (being 8.8mm).
Like this, as shown in Figure 6, in the time that the shift motion of sleeve 30 reduces, the steering force of speed-changing lever reduces, and this is because if the stroke S1 of speed-changing lever is constant, and lever ratio increases.
Meanwhile, according to the present invention, central recess 32 is formed on the center that forms the power shift gear 31 contacting with synchronous key 40, and stop surface 33 is formed as the cut forms on the opposite flank of central recess 32.Thus, while there is synchromesh when the movement according to sleeve 30, synchronous key 40 can form and contact with stop surface 33, and is supported by this stop surface 33.
That is to say, in the process that speed changes moving along with sleeve 30, synchronous key 40 slides and crosses the chamfered part outstanding from the opposite side of central recess 32, and is stopped surface 33 supports.Like this, be stopped the synchronous keys 40 that support on surface 33 and become with outstanding chamfered part and engages, thereby guarantee firm velocity variations and prevent after velocity variations that gear departs to engage.
According to the synchronizer for speed changer of the present invention, (power shift gear 31 and synchronous key 40 form the second gear teeth thickness that the first round transverse tooth thickness degree L1 contacting is formed as being greater than power shift gear 31, the conventional gear teeth thickness using), thereby the lip-deep pressure that makes to be applied to the power shift gear 31 contacting with synchronous key 40 is dispersed and reduces, thereby increase the durability of power shift gear 31 and the synchronous key 40 that contacts with power shift gear 31.
In addition, according to the present invention, the gear teeth thickness L2 that power shift gear 31 engages with clutch gear 61 is formed as thinner, thereby produces power shift gear 31 with respect to having more than needed in the length of action of clutch gear 62, makes thus the shift motion of sleeve 30 reduce the more than needed of length of action.Like this, in the time that the shift motion of sleeve 30 reduces, the steering force of speed-changing lever reduces, and this is because if the stroke of speed-changing lever is constant, and lever ratio increases.
Further, according to the present invention, in the process that speed changes moving along with sleeve 30, synchronous key 40 slides and crosses the chamfered part outstanding from the opposite side of central recess 32, and is stopped surface 33 supports.Like this, be stopped the synchronous key 40 supporting on surface 33 and form and engage with outstanding chamfered part, thereby after guaranteeing firm velocity variations and preventing velocity variations, gear departs from engagement.Thus, because the function of stop pin can be substituted by structure of the present invention, therefore remove the stop pin of conventional installation, stop pin has been installed by the expense producing thereby saved, and the weight of having saved thus synchronizer.
Although described for purposes of illustration the preferred embodiments of the invention, it is all feasible one of skill in the art will appreciate that various amendments, increase and substituting, and does not depart from scope and spirit of the present invention disclosed in the accompanying claims.
