Further, the poke rod has the round bar that one end is provided with connecting plate, and the round bar is provided with the limiting section.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the present invention is separately installed with sliding latch cylinder on two output shafts of differential mechanism, two sliding latch cylinders respectively with difference
The opposite face of fast device shell is provided with the soldered tooth being engaged, and annular groove is provided with the outside of sliding latch cylinder, is fitted with annular groove
Stir the striking gear of sliding latch cylinder movement.Two sliding latch cylinders are promoted to be moved up in output shaft simultaneously by two striking gears
It is dynamic, two sliding latch cylinders respectively the opposite face with differential carrier by engaging indented joint, make the rotating speeds of two output shafts with it is poor
The rotating speed of fast device shell is consistent, cancels the speed discrepancy of left and right wheelses, and differential locking reaction speed is fast, can select locking or solution at any time
Except locking operates.
2nd, striking gear includes socket yoke and poke rod, and socket yoke has two bayonet locks being oppositely arranged, two
Bayonet lock is connected by the fagging provided with adapter sleeve, and adapter sleeve is sleeved on poke rod, and adapter sleeve, which is provided with, prevents what poke rod from rotating
Stopper slot, poke rod are provided with the limiting section coordinated with stopper slot, and poke rod is installed on vehicle bridge housing and is flexibly connected with it.Should
Striking gear is simple in construction, easy for installation, and two bayonet locks are located in the annular groove of sliding latch cylinder, can promote sliding latch cylinder
Moved on output shaft, and do not influence sliding latch cylinder with output shaft rotation.
