Detection chock plug 2 is same 4 wheel driven differential mechanism internal spline 93 coupling.If it is bad to there is stagnant resistance in 4 wheel driven differential mechanism internal spline 93, under
Detection chock plug 2 can produce stagnant resistance phenomenon when 4 wheel driven differential mechanism internal spline 93 and can not pass through so that 4 wheel driven differential mechanism 9 drives
Lower detection chock plug 2 moves down into 4 wheel driven differential mechanism 9 and abuts to and stops on the upper surface of movable supporting seat 3 moving down, and now 4 wheel driven is poor
While fast device 9 is by gentle support, detection bar 6 also have decreased to can by upper detection switch 83 detection obtain being unable to by under
The position that detection switch 84 detects, if now operating personnel's press that goes to close plays switch, because control device is known
Only going up detection switch detects detection bar, so press still can not drive.If 4 wheel driven differential mechanism internal spline 93 is not deposited
Bad in stagnant resistance, then lower detection chock plug 2 can pass through 4 wheel driven differential mechanism internal spline 93, and now 4 wheel driven differential mechanism 9 can be under not
Drop in the case of pressure detection chock plug 2 and be shelved on movable supporting seat 3, two detection switch are all not detected by detecting
Bar, when now operating personnel drives press, then control device can make press play and drive corresponding press mechanism to push, under
4 wheel driven differential mechanism 9 is pushed away, the part such as 4 wheel driven differential mechanism 9 and movable supporting seat 3 all declines and makes 4 wheel driven differential mechanism 9 He under press mechanism
Differential bearing 41 is assembled together.After press rises, in the presence of the second return spring 33, movable supporting seat 3, connecting rod
5 and first detect that chock plug 1 resets；In the presence of the first return spring 22, the second detection chock plug 2 and detection bar 6 reset.
Go to judge that the differential mechanism being assembled is 4 wheel driven differential mechanism or two drives are poor without using person when therefore the present invention uses
Differential mechanism set is directly set to the enterprising luggage of the present invention and joins by fast device.Also and without the position going to observe detection bar to sentence
Break and whether can start press and axle is assembled, only observe that differential mechanism can smoothly amplify and can go in the present invention
Drive press activate switch, if differential mechanism is defective products, in the presence of control device, press will not push and by differential
Device bearing and differential mechanism shell are assembled together, very convenient during use.
