Embodiment
In order to more clearly understand technology contents of the present invention, describe in detail especially exemplified by following examples, its object is only better understand content of the present invention but not limit the scope of the invention.
Embodiment 1
As shown in Figure 1, a kind of gearshift with unique phase angle for motor, comprise motor 1, first axle 2, second axle 3, tooth hub 51, tooth cover 52 and one group of phase angle Synchronization Component, this group phase angle Synchronization Component comprises in conjunction with tooth 11 and synchronizing ring 40.
Output shaft and first axle 2 of motor 1 are rigidly connected.
Be rigidly connected in conjunction with tooth 11 and the first axle 2.
What synchronizing ring 40 was coaxial is arranged in conjunction with between tooth 11 and tooth hub 51, and synchronizing ring 40 is furnished with external splines 41 and the second rubbing surface 42, synchronous ring structure is identical with the friction synchronizing ring in lock ring type synchronizer of the prior art.
Second axle 3 and the first axle 2 pass through the layout of bearing element on the same axis.
What tooth hub 51 was coaxial is arranged on the second axle 3, and is rigidly connected with the second axle 3.
Tooth cover 52 is disposed coaxially on outside tooth hub 51, and is slidably connected by spline and tooth hub 51.
In the present embodiment 1, tooth cover has three special-shaped teeth groove 521, three special-shaped teeth groove different from the whole depth of other teeth groove and does not form Central Symmetry; Be provided with in conjunction with corresponding on tooth three heteromorphic teeths 111 engaged with special-shaped teeth groove, and towards the side of synchronizing ring, there is the first rubbing surface 112 in conjunction with tooth; Synchronizing ring has the second rubbing surface 42 of corresponding first rubbing surface, and synchronizing ring has the external splines 41 of the internal spline 522 of corresponding teeth cover, and the external splines 41 of synchronizing ring is provided with relative chamfering 421 with the internal spline 522 that tooth overlaps, see Fig. 6 and Fig. 7.
Preferably, in conjunction with the structural drawing of tooth 11 see Fig. 3 a, in all spline tooths in conjunction with the external splines 41 that tooth 11 is arranged, there is the whole depth of three heteromorphic teeths 111 than other tooth depth, further, assuming that angle is θ 1 between first heteromorphic teeth and second heteromorphic teeth, the angle between second heteromorphic teeth and the 3rd heteromorphic teeth is θ 2, angle between 3rd heteromorphic teeth and first heteromorphic teeth is θ 3, then have following relation:
θ1＝θ3………………………………………………(1)
θ1≠θ2………………………………………………(2)
Corresponding, the structural drawing of tooth cover 52, see Fig. 3 b, in all spline tooths of the internal spline 522 that tooth cover 52 is arranged, also have the teeth groove overall height of three special-shaped teeth groove higher than other teeth groove, and the arrangement relation of each special-shaped teeth groove is corresponding with in conjunction with the heteromorphic teeth on tooth 11.
Due to special-shaped teeth groove on tooth cover 52 be not circumference uniform distribution in conjunction with the heteromorphic teeth on tooth 11, therefore an angular orientation that can engage only is had in conjunction with tooth 11 and tooth cover 52, namely when in conjunction with the heteromorphic teeth position on tooth 11 and tooth cover 52 on special-shaped tooth slot position completely to correspondence time tooth cover 52 just can engage with in conjunction with tooth 11, under other angle, interfere because heteromorphic teeth and normal teeth groove exist, tooth cover 52 cannot combine with in conjunction with tooth 11, thus makes tooth cover 52 and the corresponding relation in conjunction with tooth 11 with unique phase angle;
In other embodiments, the group number in conjunction with the special-shaped teeth groove on heteromorphic teeth on tooth 11 and tooth cover 52 can also be 1 or 2; And can also be lower than other tooth in conjunction with the whole depth of the heteromorphic teeth on tooth 11, the teeth groove overall height of the special-shaped teeth groove on tooth cover 52 is lower than other teeth groove; Angle in conjunction with each group of heteromorphic teeth on tooth 11 and tooth cover 52 and special-shaped teeth groove can also be all unequal.
As a kind of preferred embodiment, as shown in Fig. 2 a, Fig. 2 b, Fig. 2 c, Fig. 2 d, the shift process principle of the present embodiment is as follows:
See Fig. 2 a, be off state, now the first axle 2 and the second axle 3 be in the state of disconnecting, unpowered connection between the first axle 2 and the second axle 3, now the first axle 2 and the second axle 3 has different rotating speeds.
See Fig. 2 b, be sync state, tooth cover 52 is by synchronizing ring 40 and compress in conjunction with tooth 11, and because speed discrepancy exists, it is mobile to continuing in conjunction with tooth 11 that tooth cover 52 cannot cross synchronizing ring 40.Under synchronizing ring 40 and the effect in conjunction with the frictional force between tooth 11, the speed discrepancy between the first axle 2 and the second axle 3 is more and more less, until the speed discrepancy between the first axle 2 and the second axle 3 is zero.
Compaction process principle is specific as follows: tooth cover 52 is in the process in conjunction with tooth movement, due to tooth cover 52 having internal spline 522, can contact with the external splines 41 in synchronizing ring 40, due to interior, external splines end face has relative chamfering, under the effect of chamfering, tooth cover 52 can push synchronizing ring 40 to moving in conjunction with tooth (now tooth cover 52 is identical with synchronizing ring 40 rotating speed): when synchronizing ring 40 moves to when contacting in conjunction with tooth 11, due to different with synchronizing ring 40 rotating speed in conjunction with tooth 11, friction can be produced in conjunction with between the first rubbing surface meeting of tooth 11 and the second rubbing surface of synchronizing ring, owing to not having other power to input in conjunction with tooth 11, so understand the continuous rotating speed close to synchronizing ring 40 until identical with the rotating speed of synchronizing ring 40 in conjunction with tooth 11 rotating speed under the effect of frictional force.
See Fig. 2 c, be asynchronous mode, between tooth cover 52 is in after synchronizing ring 40 and combines in conjunction with tooth 11, because synchronizing ring 40 loses the pressure that tooth cover 52 provides, synchronizing ring 40 and disengaging in conjunction with tooth 11.Now motor 1 makes the first axle 2 raise or reduce by speed governing, makes the rotating speed of the first axle 2 different with the rotating speed of the second axle 3.
Synchronizing ring 40 can be as follows with the principle disengaged in conjunction with tooth 11:
Along with the disappearance of speed discrepancy, also disappear in conjunction with the frictional force between tooth 11 and synchronizing ring 40, now, tooth cover 52 just can be pushed synchronizing ring 40 open and continue to move forward: namely after its synchronized rotation, synchronizing ring can disengage in conjunction with tooth thereupon; This is because: spline is straight-tooth, after the internal spline 522 of tooth cover 52 crosses the chamfering of the external splines 41 in synchronizing ring 40, the direction (namely movement direction) overlapping the power of 52 due to splined joint face and tooth is parallel, so the power that tooth cover 52 is subject to just cannot be delivered in synchronizing ring 40, and internal spline has gap, so synchronizing ring 40 will be rocked in the interstice coverage of the internal spline of tooth cover, the second rubbing surface 42 in synchronizing ring 40 is disengaged with the first rubbing surface in conjunction with tooth 11.
See Fig. 2 d, for bonding state, due to tooth cover and the phase angle corresponding relation in conjunction with tooth existence anduniquess, when tooth cover 52 is with time incorrect in conjunction with tooth 11 phase angle, tooth cover 52 cannot combine with in conjunction with tooth 11, because the rotating speed of the first axle 2 is different with the rotating speed of the second axle 3, therefore tooth cover 52 is different with in conjunction with tooth 11 rotating speed, tooth cover 52 and constantly change in conjunction with the phase angle between tooth 11, when tooth cover 52 with when meeting design point in conjunction with the phase angle between tooth 11, tooth cover 52 with combine in conjunction with tooth 11.In the process combined, tooth cover 52 and in conjunction with between tooth 11 in conjunction with spline absorb tooth cover 52 and in conjunction with between tooth 11 speed discrepancy produce energy, make tooth cover 52 and in conjunction with between tooth 11, there is identical rotating speed, and then make the rotating speed of the first axle 2 identical with the rotating speed of the second axle 3, and make the first axle 2 set up power with the second axle 3 to be connected.
