Between part 15, the part in the second thrust plate 163 and the first thrust plate 161 is arranged in ball 103.
As shown in figure 4, the first thrust plate 161 and the second thrust plate 163 can be structured as annular slab, in the first thrust plate
161 and second are provided with half ball 105 for being suitable for cooperate with ball 103 in push plate, and multiple half ball, 105 uniform intervals are arranged
In the circumferential direction of the first thrust plate 161 and the second thrust plate 163.Ball 103 is arranged in the first thrust plate 161 and the second thrust plate
Between 163 and it is embedded into half ball 105, the sphere diameter of half ball 105 is not less than the diameter of ball 103, at least portion of ball 103
Point protrude from the second thrust plate 163, between electromagnetism part 15 and the second thrust plate 163 when transmitting thrust, electromagnetism part 15 first with
Ball 103 contact, and the second thrust plate 163 can always with differential casing 11 rotate, by ball 103 first with electromagnetism part
15 contacts avoid the first thrust plate 161 and contact with the direct of electromagnetism part 15, reduce the first thrust plate 161 and electromagnetism part 15
Between friction, reduce the generation of noise and vibration.
Half ball 105 being arranged on the first thrust plate 161 is the first half ball, is arranged on the second thrust plate 163
Half ball 105 is the second half ball, can fix between the first thrust plate 161 and the second thrust plate 163, make the first thrust plate
161 and second the distance between thrust plate 163 it is fixed, the first half ball are corresponded with the second half ball, and are formd and be used for
The ball installation position of ball 103 is installed, each ball 103 is embedded in ball installation position, and ball 103 can be in ball installation position
Middle rotation, ball 103 with electromagnetism part 15 when contacting, since the first thrust plate 161, the second thrust plate 163 are opposite with electromagnetism part
15 rotations, therefore, ball 103 will generate relative friction, and the first thrust plate 161, second when contacting with electromagnetism part 15
It is rolling friction between thrust plate 163 and ball 103, and between ball 103 and electromagnetism part 15 is also rolling friction, greatly reduces
Frictional dissipation inside differential assembly 1 reduces vibration, extends the service life of differential assembly 1.

And it can be slided along the pivot center of differential casing 11.
Can be set sliding rail on the support frame, sliding rail along differential casing 11 rotation it is axially extending, sliding rail is used for
Electromagnetism part 15 is supported, while electromagnetism part 15 slides on the extending direction of sliding rail, after electromagnetism part 15 is powered, electromagnetism part 15 and poor
Active force is generated between fast device shell 11, electromagnetism part 15 is mobile towards differential casing 11, and sliding rail can be used for being oriented to electromagnetism part
15, and make the mobile stabilization of electromagnetism part 15.
According to one embodiment of present invention, it is provided with return unit 104 between lock piece 16 and the first axle shaft gear (12),
Differential assembly 1 according to the present invention has lockup state and unlocked state, when electromagnetism part 15 does not work, the inside of lock piece 16
It is provided with return unit 104 between the outside of the first axle shaft gear 12, for lock piece 16 to be isolated with the first axle shaft gear 12
It opens, keeps the first axle shaft gear 12 in the unlocked state.After the energization of electromagnetism part 15, electromagnetism part 15 drive lock piece 16 mobile and with
The cooperation of first axle shaft gear 12, by after 12 locking of the first axle shaft gear, electromagnetism part 15 powers off lock piece 16, and return unit 104 is suitable for
It is separated between driving lock piece 16 and the first axle shaft gear 12, driving lock piece 16 resets, and makes lock piece 16 and the first half axle gear
Wheel 12 is detached from cooperation.
In one embodiment of the invention, return unit 104 is it is so structured that wave spring.
Differential assembly 1 according to an embodiment of the present invention is specifically described below according to attached drawing.
Locking differential assembly may include differential shell, differential gear set and lockable mechanism, and differential casing 11 is configured to one
A or multiple discreet components and differential mechanism cavity for accommodating differential gear set is limited, differential gear set is subjected to defeated
Enter torque, and differential torque exported to two sides wheel, lockable mechanism be configured to can be selected from by differential gear set
One axle shaft gear 12 is locked to differential casing 11, so that the first axle shaft gear 12, the second axle shaft gear 13 surround differential carrier
The rotary shaft of body 11 rotates jointly, and lockable mechanism has two states, in the first state, 15 no power of electromagnetism part, by multiple
The position support of part 104 separates lock piece 16 with the first axle shaft gear 12, so that the second blade tooth and the first semiaxis on lock piece 16
First blade tooth in 12 outside of gear is detached from, and in this case, the first axle shaft gear 12, the second axle shaft gear 13 can be relative to differentials
Device shell 11 rotates, so that there are speed differences between the first axle shaft gear 12 of permission and the second axle shaft gear 13.
Under second state, electromagnetism part 15, which is powered, to be generated magnetic force and adsorbs differential casing 11, and electromagnetism part 15 is on the support frame
It is mobile, electromagnetism part 15 along differential casing 11 rotation axially adjacent to differential casing 11, and drive the first thrust plate 161 and the
Two thrust plates 163 then push nesting 162 mobile, so that the second blade tooth is engaged with the first blade tooth, in this case, first
Axle shaft gear 12 is engaged with nesting 162, and then is locked on differential casing 11 and is rotated jointly, thus the first semiaxis of locking
Gear 12 makes the first axle shaft gear 12, the second axle shaft gear 13, nesting 162 and differential casing 11 form rigid connection, eliminates
Speed difference exports power smoothly.
Ball 103 is arranged between the first thrust plate 161 and the second thrust plate 163, and electromagnetism part 15 is connect by ball 103
Touching, so that electromagnetism part 15 be avoided directly to contact with the first thrust plate 161 or the second thrust plate 163.First thrust plate 161 and second
The split settings of thrust plate 163 can be convenient in the installation of ball 103, respectively in the first thrust plate 161 and the second thrust plate
On 163 on corresponding position, two halves are respectively opened as ball split using the interface between the first thrust plate 161 and the second thrust plate 163
Ball 105 is for storing ball 103, and half ball 105 is through hole, after ball 103 is installed, 103 a part protrusion of ball
In the second thrust plate 163, ball 103 is directly contacted with electromagnetism part 15.For the rolling convenient for ball 103, it need to guarantee half ball 105
Sphere diameter be greater than ball 103 sphere diameter.It can be fixedly connected in several ways between first push plate and the second thrust plate 163,
For example, can be fixed by fastener or/and adhesive or/and riveting.First thrust plate 161 and the second thrust plate 163 arrangement
Between electromagnetism part 15 and differential casing 11, to avoid the influence to periphery magnetic loop, the first thrust plate 161 and the second thrust
Plate 163 is made of non-magnetic material, such as plastic material, aluminium sheet, stainless steel product etc..
