Embodiment
Below in conjunction with accompanying drawing 1-8, detailed further describing is carried out to the utility model.
Embodiment one, as shown in accompanying drawing 1,2, a kind of increasing turns round differential locking-device, comprise differential mechanism frame 1, two and be inserted into the wheel shaft 2 of differential mechanism frame 1 both sides, the driven disc 11 be fixedly connected with differential mechanism frame 1 and the planetary pinion 12 engaged with two wheel shafts 2 respectively, described differential mechanism frame 1 both sides are fixedly installed nipper wheels 3, described wheel shaft 2 is equipped with sliding gear 4 by keyway shaft part 21 flip sleeve, described nipper wheels 3 is coaxially arranged with wheel shaft 2, and described nipper wheels 3 and sliding gear 4 are engaged by lazy-tongs.Described lazy-tongs comprise synchronizing shaft 51 and are fixedly installed on the synchromesh gear 52 at synchronizing shaft 51 two ends respectively, a described synchromesh gear 52 engages with nipper wheels 3, another synchromesh gear 52 is corresponding with sliding gear 4 position, and both are engageable or be separated at any time, and described synchronizing shaft 51 be arranged in parallel with wheel shaft 2.The keyway of described keyway shaft part 21 is indent keyways, and described keyway shaft part 21 is parallel indent shaft with key ways.Described sliding gear 4 is moved on keyway shaft part 21 by drive unit, engages synchromesh gear or is separated with it.Described drive unit can be shift fork, driving lever, plectrum, bracing wire, spring, oil cylinder, cylinder.
Working principle: shown in the present embodiment is that two wheel shafts 2 all arrange lazy-tongs, transmission shaft 6 engage with the driven disc 11 of differential mechanism frame 1 again by planetary pinion 12 for wheel shaft 2 provides power, the technical program is formative gear engagement driving between differential mechanism frame 1 and wheel shaft 2, has so just skipped the object that planetary pinion 12 reaches locked differential mechanism; And if just can export different moments of torsion from the tooth of original drive connection than different, adaptability is stronger.
Working procedure: because both sides principle is identical, and therefore synchronous working only describes side working procedure, and it should be noted that the one-sided lazy-tongs that arrange also can complete locked, only can not change moment of torsion also not as bilateral arranges more stable, when differential mechanism works, transmission shaft 6 engages with the driven disc 11 of differential mechanism frame 1, planetary pinion 12 is again by transmission of power to two wheel shaft, this is existing differential mechanism basic structure, when the locked differential mechanism of needs, the sliding gear 4 be sleeved on wheel shaft 2 is stirred to synchromesh gear 52 side and is engaged with by shift fork (drive unit), now the power of transmission shaft 6 is passed to nipper wheels 3 by the driven disc 11 of differential mechanism frame 1 and is directly passed to wheel shaft 2 by lazy-tongs, what this completes differential mechanism differential function is locked, power is directly passed to wheel shaft, and also can according to actual demand can arrange locked after output torque.
Embodiment two, as shown in accompanying drawing 3,4, are with embodiment one difference, and the driving cog of tooth engaged 3, synchromesh gear 52 and sliding gear 4 is than different.
Embodiment three, and as shown in Figure 5, be with embodiment one difference, tooth engaged 3 number of teeth identical with the gear diameter of sliding gear 4 is identical.
Embodiment four, as Fig. 6, 7, shown in 8, be with embodiment one difference, described differential mechanism frame 1 both sides are fixedly installed nipper wheels 3, two described synchromesh gears 52 of the lazy-tongs of one or both sides are the active synchronization gear 521 engaged with nipper wheels 3 and the driven synchromesh gear 522 engaged with sliding gear 4 respectively, described active synchronization gear 521 is identical with the number of teeth with nipper wheels 3 diameter, described driven synchromesh gear 522 comprises the first driven synchromesh gear 5221 and the second driven synchromesh gear 5222, described second driven synchromesh gear 5222 is identical with active synchronization gear 521, described first driven synchromesh gear 5221 is between the second driven synchromesh gear 5222 and active synchronization gear 521, the diameter of described first driven synchromesh gear 5221 is greater than the diameter of described second driven synchromesh gear 5222, described sliding gear 4 is provided with the first sliding gear 41 and the second sliding gear 42 that synchromesh gear 5221 driven with first and the second driven synchromesh gear 5222 respectively engage, described first sliding gear 41 is conflicted with the second sliding gear 42 and is fixedly connected with, and the clearance distance between described first driven synchromesh gear 5221 and the second driven synchromesh gear 5222 is greater than the width of the second sliding gear 42.
Working principle: working principle is identical compared with embodiment one, difference is only that driven synchromesh gear 522 and sliding gear 4 have two groups of teeth than different engaging tooth wheels, have different moments of torsion when different gear trains engages and be passed to wheel shaft 2, wherein the tooth of a group is more identical with the moment of torsion exported during differential drive than the moment of torsion being sent to wheel shaft.
Working procedure: is as shown in Figure 6 now differential mechanism working state, and power is passed to the driven disc 11 on differential mechanism frame 1 by transmission shaft 6, then is passed to two wheel shafts 2 by planetary pinion 12.When needs locking differential function but do not need change output torque time, as shown in Figure 7, sliding gear 4 is mobile to differential mechanism frame 1 side (inner side), make to be passed to the driven disc 11 on differential mechanism frame 1 by transmission shaft 6 when the second sliding gear 42 engages now power with the second driven synchromesh gear 5222, directly pass through active synchronization gear 521, the driven synchromesh gear 5222 of synchronizing shaft 51, second and the second sliding gear 42(and sliding gear 4 by nipper wheels 3) be passed to wheel shaft 2, tooth now than transmission and original tooth than transmission just as, therefore moment of torsion does not change.When needing locked differential mechanism function to change the output of moment of torsion again, as shown in Figure 8, first sliding gear 41 of the sliding gear 4 in left side is engaged with the first driven synchromesh gear 5221, the sliding gear 4 on right side engages with the driven synchromesh gear 522 of synchromesh gear 52 simultaneously, now power is directly passed to two wheel shafts by differential mechanism frame 1 and locking mechanism, now by tooth than changing output torque from original the different of driving cog ratio.
Scheme shown in embodiment four is a kind of scheme, and as shown in Figure 6, right side also can be identical with left side, and arranging of tooth ratio can be arranged as required.
One-sided setting can be locked principle, when the wheel shaft 2 of side is locked with differential mechanism frame 1, namely the axle end gear of this side engages locked with the planetary pinion 12 of differential mechanism frame 1, and the end tooth of two wheel shafts wheel is engaged by planetary pinion 12, and therefore the wheel shaft 2 of opposite side is also locked with differential mechanism frame 1.
Tooth ratio is exactly gear ratio.
The above mode of execution is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
