Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figures 1 to 4, magnetic-type limited slip differential of the present utility model, comprise the shell 1 be sleeved on semiaxis, be sequentially set with the left friction plate group 2, cam disk 3, the left half axle gear 4 that are sleeved on left half axle in this shell 1, be sleeved on successively right axle shaft gear 6 and right friction plate group 16 on right axle shaft; Be provided with all upper planetary gear 5 and lower planetary gear 17 with left half axle gear 4 and 6 engagements of right axle shaft gear in shell 1 inside; Described left friction plate group 2 and cam disk 3 spline fitted; The side of described cam disk 3 coordinates with the side cam of left half axle gear 4, between described upper planetary gear 5 and lower planetary gear 17, is provided with reaction block 7, described right axle shaft gear 6 and right friction plate group 16 spline fitted; Be provided with the magnetic-type lockable mechanism in described shell 1, this magnetic-type lockable mechanism comprises flywheel mechanism 8 and the locking carriage 9 cooperatively interacted, described flywheel mechanism 8 comprises with the flywheel shaft 10 of cam disk 3 gears engagements and is sleeved on the magnetosheath 11 on this flywheel shaft 10, and the peripheral magnetic force of described magnetosheath 11 is combined with disengaging pawl 12; This disengaging pawl 12 is comprised of the two-part that are hinged; Described locking carriage 9 is sleeved on the bracket axle 14 that is fixed in shell 1 inside, is provided with the locking pawl 15 coordinated with disengaging pawl 12 on this locking carriage 9.For the torsional spring type lockable mechanism, during automobile normal running, the disengaging pawl 12 of flywheel mechanism 8 is held tightly under the effect of torsion spring, while skidding, produce differential, flywheel mechanism 8 starts rotation, the centrifugal force of flywheel mechanism 8 rotations overcomes torsion makes lockable mechanism automatically open work, the all parts locking is become to an integral body, transmit power to a non-slip end, vehicle is advanced.Due to the frequent use of torsion spring, use long-time rear mechanical property to reduce, the probability broken down is larger.The utility model, owing to adopting the magnetic-type lockable mechanism, utilizes the work of Magnetic Control lockable mechanism, even if use on long-time rear mechanical property, too large variation can not occur yet, and has more serviceability, makes rate of fault reduce.During automobile normal running, whole magnetic-type limited slip differential revolves round the sun around semiaxis, when skidding appears in left side wheel, left half axle gear 4 is rotated further, with crossing cam engagement with cams dish 3, rotate, cam disk 3 makes flywheel mechanism 8 rotations by the gear outer gearing again, when the left and right wheels speed discrepancy reaches setting value, disengaging pawl 12 in flywheel mechanism 8 is automatically opened with the locking pawl 15 on locking carriage 9 and is engaged under the effect of centrifugal force, thereby make flywheel mechanism 8, cam disk 3 stops rotation successively, and left half axle gear 4 now still is rotated further under the driving force effect, thereby promoted to move right by cam disk 3 by camming surface, and then driving a reaction piece 7 also moves right, reaction block 7 makes again the right axle shaft gear move right and then compresses right friction plate group 16.Simultaneously, cam disk 3 also is moved to the left under the reaction of left half axle gear 4, then compress left friction plate group 2, shell 1 connects with left friction plate group 2 hole axles, left friction plate group 2 and cam disk 3, right axle shaft gear 6 splined, finally make shell 1, left half axle gear 4, right axle shaft gear 6 be connected as a single entity, and left and right wheels obtains identical rotating speed, thereby be that power passes on the non-slip wheel of opposite side by effective torque, vehicle is advanced.
