(formation of speed change gear)
Below the speed change gear 40 that is applied to 2-4 retaining lazy-tongs 23 is described.In addition, in the present embodiment, the speed change gear that is applied to 3-5 retaining lazy-tongs 22 is same formation, and the speed change gears that are applied to 6 retaining lazy-tongs 24 are but that the stroke range of gearshift axle when gear switches is different be same formation, therefore omit to illustrate and explanation.
As shown in Figure 1, in the present embodiment, utilize 39 pairs of gearshift actuator that constituted by the valve body that possesses the ON/OFF solenoid valve to make the selector fork 31 of the sleeve 23A action of 2-4 retaining lazy-tongs 23 carry out displacement and drive.As shown in Figure 2, the top of selector fork 31 is U word shape roughly, is accommodated in the recess that forms in the mode around the outer circumferential face of sleeve 23A shown in Figure 1, and 23A engages with sleeve.And as shown in Figure 2, the base portion of selector fork 31 is fixed in the central part of the gearshift axle 33 of elongated pole shape.
As shown in Figure 1, gearshift axle 33 is configured to parallel with the 2nd input shaft 6 as running shaft.As depicted in figs. 1 and 2, the two end part of gearshift axle 33 are inserted into the supported hole 42 of the cylindrical shape that is formed at case of transmission 41, occlusion of openings end respectively.Therefore, gearshift axle 33 can slide with respect to supported hole 42, and can be chimeric airtightly.The space of being divided by the inwall of the end face at the two end part of this gearshift axle 33 and supported hole 42 constitutes that the slip of following gearshift axle 33 is moved and the air chamber 43 that makes volume-variation.Portion becomes the bearing surface of circular flat in the supported hole 42, becomes the retainer 45 of the stroke range of regulation gearshift axle 33.
As Fig. 4～shown in Figure 6, gearshift axle 33 is formed with the air passageways 33A that connects along axle direction.Gearshift axle 33 is made of tubing.And at the two end part of this gearshift axle 33, be that the two end part of air passageways 33A are provided with restriction 44, restriction 44 has throttling opening portion 44A.Throttling opening portion 44A is set at following diameter dimension: the travelling speed at gearshift axle 33 surpasses under the situation of fixing speed, from the air quantity of the side outflow of the air chamber 43 volume decrease less than side's air chamber 43.
As shown in Figure 2, connecting shift fork portion 34 at the base portion of selector fork 31, the end of shift fork portion 34 is attached to above-mentioned gearshift actuator 39.Gearshift actuator 39 makes shift fork portion 34 reciprocating in the direction parallel with gearshift axle 33 (among the figure shown in the arrow A).
Gearshift axle 33 is followed the switching of gear and is utilized gearshift actuator 39 to move at axle direction.Follow the movement of this gearshift axle 33, air chamber 43 is flexible.When shifting gears axle 33 when retainer 44 moves, the air in the air chamber 43 play damping function behind mobile predetermined distance.Therefore, the air in the air chamber 43 has following effect: prevent that gearshift axle 33 from knocking with retainer 45 collisions.
Generally, when the gearshift action of gear begins, gearshift axle 33 makes sleeve move towards driving gear from neutral gear position shown in Figure 4, and sleeve needs most load hindering position (sleeve is pressed synchronizing ring, and the drive range of friction is arranged at the conical surface of synchronizing ring and gear side).Therefore, as shown in Figure 5, gearshift axle 33 is set at: can not slow down (more than the fixing speed) crossing the preceding travelling speed (shift speed) of sleeve 23A that makes in this obstruction position (counting the position of distance L 1 from neutral gear position).That is, gearshift axle 33 is set at: damping function is constant big before crossing this obstruction position, makes the travelling speed (shift speed) of sleeve 23A can not slow down.
And gearshift axle 33 is set at: when crossing the obstruction position, travelling speed increases, and follows in this, presses liter in the air chamber 43, the performance damping function.Particularly, throttling opening portion 44A is set at following opening diameter: the travelling speed at gearshift axle 33 surpasses under the situation of fixing speed, and the air quantity that flows out from air chamber 43 more reduces less than the volume of this air chamber 43.
As mentioned above, in the speed change gear 40 that possesses 2-4 lazy-tongs 23, gearshift begins and needs most load in the obstruction position usually, so need make that damping function is constant big before crossing the obstruction position.In Fig. 3, the damping position is made as the position of counting distance L 3 from neutral gear position.In addition, shift speed F4 shown in Figure 3 is for the gear that makes switching and sleeve required speed synchronously, and shift speed F5 is the hump speed of not sounding when contacting with retainer 45 in the end of gearshift axle 33.
As Fig. 4～shown in Figure 6, utilize following damping function in the present embodiment: follow the movement of gearshift axle 33, the volume of air chamber 43 dwindles, and follows in this, and air is full of air chamber 43 compressedly, and the travelling speed of gearshift axle 33 is reduced.That is, when the travelling speed of gearshift axle 33 was faster than fixing speed, air chamber 43 interior pressure sharply rose with the movement of gearshift axle 33, can make the travelling speed reduction of gearshift axle 33 based on the damping effect of air chamber.Therefore, in this speed change gear 40, can reduce the Back drop that the impact sound that the end of following gearshift axle 33 sends with retainer 44 collisions and sleeve 23A and 4 keep off driving gears 11.
In the speed changer of two clutch types of the automatic transmission 100 of present embodiment, situation and the situations from 4 retaining driving gears 11 to the gearshift of 2 retaining driving gears 10 of the gearshift of carrying out usually of (being 4 retaining driving gears 11 in the present embodiment) from neutral gear position to gear are arranged.In the present embodiment, also be set in these cases: as shown in Figure 3, before crossing the obstruction position, make shift speed can not slow down.And also be set under the two situation: after crossing the obstruction position, compressed air is full of air chamber 43 and produces damping function.
(action of speed change gear, effect)
The situation of carrying out the gearshift of (being 4 retaining driving gears 11 in the present embodiment) from neutral gear position to gear shown in Figure 4 is following situation: when watching with the state of gearshift axle 33, from state shown in Figure 4, gearshift axle 33 is towards retainer 4 displacement distance L2.In such gearshift, preestablish the diameter dimension (for example 16mm) of air passageways 33A and the diameter dimension (for example 0.1mm) of throttling opening portion 44A, make and keep the pressure of air chamber 43 lower in the end of gearshift axle 33 before by the obstruction position (position of corresponding air chamber 43 when being positioned at the obstruction position with sleeve 23A) of leaving distance L 1 from neutral gear position.Gearshift axle 33 begins mobile with F1 speed, the pressure in the air chamber 43 is P1, and the air that flow in the air passageways 33A from air chamber 43 is that small flow S1(is with reference to Fig. 4).
Be set in the present embodiment: constant big by the damping function based on the interior pressure of air chamber 43 before hindering the position in the end of gearshift axle 33.In addition, in the present embodiment, when the stroke of axle 33 the integral body of will shifting gears for example was made as 8mm, the mobile for example position of 2mm degree (stroke with respect to integral body is about 25～30%) was to hinder the position.At this, the air in the air chamber 43 has along with compressed, the character that pressure rises and volume reduces.But the interior pressure P2(of air chamber 43 is with reference to Fig. 5 before hindering the position) there is not the high degree that reduces to the speed that makes gearshift axle 33, damping function is little.At this moment, gearshift axle 33 with F2(with reference to Fig. 5) speed moves.In addition, the flow that flow into the air in the air passageways 33A from air chamber 43 of this moment is the flow S2 that is a bit larger tham above-mentioned flow S1.
As shown in Figure 6, being positioned at from neutral gear position in the end of gearshift axle 33 is for example 7mm of distance L 3() near the time, gearshift axle 33 speed with the F3 higher than F2 move.Therefore, the internal force of air chamber 43 becomes among the higher pressure P 3(figure of specific pressure P2 shown in the arrow.), produce the damping function of the speed reduction that makes gearshift axle 33.Be set at: the flow S3 that flow into air air passageways 33A in from air chamber 43 this moment is greater than above-mentioned flow S2, but since the diameter dimension of throttling opening portion 44A set, less than the volume decrease of air chamber 43.Utilize such effect, the travelling speed of gearshift axle 33 is reduced, can avoid its end and retainer 45 sharply to collide.Consequently, the sending of Back drop that also can suppress sleeve 23A and 4 retaining driving gears 11.In addition, As time goes on, air moves to the opposing party's air chamber 43 via throttling opening portion 44A, air passageways 33A, the opposing party's throttling opening portion 44A, thereby pressure P 3 reduces.
Like this, when the stroke of gearshift axle 33 was contained distance L 2 integral body, gearshift axle 33 slowed down, and gearshift sound alleviates.The variation of the travelling speed of this gearshift axle 33 depends on the diameter of the throttling opening portion 44A that makes the restriction 44 that air moves, optimum diameter can be according to the layout of lazy-tongs optimization.
In addition, Fig. 7 illustrates travelling speed and the time relation of the gearshift axle 33 in the gearshift action.In Fig. 7, (1) is illustrated under the situation that gearshift axle 33 is positioned at neutral gear position speed is in the 0m/s.In Fig. 7, (2) are while be that gearshift axle 33 accelerates to be equivalent to position shown in Figure 5 to hindering the process that move the position.In Fig. 7, (3) are gearshift axles 33 by hindering the position, beginning to produce the situation of damping function, are equivalent to position shown in Figure 6.In Fig. 7, (4) are the situations that gearshift axle 33 arrives retainer 45, and speed is 0m/s.
More than the speed change gear 40 of present embodiment is illustrated, but except 2-4 lazy-tongs 23, the utility model being applied to 6 retaining lazy-tongs 24,3-5, to keep off lazy-tongs 22 be self-evident.In addition, under the situation of 6 retaining lazy-tongs 24, only the sides at 6 retaining lazy-tongs 24 dispose gear (6 retaining driving gear 12), but gearshift axle 33 neutral gear position with reciprocating between 6 gears are put aspect situation with 2-4 lazy-tongs 23 different, and other constitute equally.
In the present embodiment, can be for example the 2nd input shaft 6 running shafts such as grade and for example finishing synchronously of 4 retaining gears such as driving gears 11, gearshift axle 33 towards being disposed at supported hole 42 in the retainer 45 of portion when moving, utilize the compressed-air actuated damper effects that riddle in the air chamber 43 to make the travelling speed reduction of gearshift axle 33.Therefore, make gearshift axle 33 mobile with required shift speed (perhaps pressure) such as the synchronous effect of for example synchronous engaging mechanism such as 2-4 lazy-tongs 23 grades, and can utilize the damping function of air after with EOS, to reduce because gearshift spools 33 contacts the impact sound that sends with retainer 44 in the supported hole 42.
In the present embodiment, can constitute the damper of gearshift axle 33 by in gearshift axle 33, being provided with air passageways 33A and restriction 44, therefore can simplify the formation of damper.In addition, in the present embodiment, be compressed-air actuated damper, therefore can be as the damper that uses oil, damping changes according to the temperature variation of oil, obtains stable damping.
In the present embodiment, exchange gear shaft 33 is made of the valve body that possesses the ON/OFF solenoid valve in the gearshift actuator 39 that axle direction carries out the displacement driving, therefore can realize compactness, lightweight and the cost degradation of speed changer.In addition, has following advantage: can simplify the control of speed change gear 40 by using the ON/OFF solenoid valve.
In the present embodiment, utilize tubing to form gearshift axle 33, therefore can in gearshift axle 33, form air passageways 33A easily.And, in the present embodiment, make gearshift axle 33 be tubing, can make 33 lightweights of gearshift axle thus, the inertial force of the axle 33 that therefore can reduce to shift gears can make the speed of gearshift axle 33 reduce reliably.
In the present embodiment, be provided with restriction 44 at the axial two end part of gearshift axle 33, can make the air chamber 43 at the two ends that are positioned at gearshift axle 33 be roughly the same volume thus.Therefore, can produce certain damping function no matter shift gears axle 33 directions that move.
