It is contained on axle tube 1-2, slidably engages after set is enclosed within semiaxis 5, be directly connected on wheel hub.
This operation principle taking turns limit differential lock vehicle bridge is that the power of electromotor exports main gearbox assembly through variator
2, the power that variator exports is slowed down by main gearbox assembly 2 again, to increase torque, through bead assembly 2-19, passes to master
Dynamic bevel gear 2-16, passes to differential mechanism after driven wheel of differential 2-12 slows down.
When automobile is at straight-line travelling, the driven wheel of differential 2-12 of main gearbox assembly 2 drives differential carrier 2-11 to rotate,
Differential carrier 2-11 drives planetary gear axle to rotate, and planetary gear axle drives planetary gear 2-14 revolution, and axle shaft gear 2-10 exists
Synchronized rotating Vortex under the clamping of planetary gear 2-14, now, planetary gear 2-14 only revolves round the sun, the most automatically, left and right wheels and turn
The speed rotating speed equal to driven wheel of differential 2-12；When automobile turning, planetary gear 2-14, while revolution, creates rotation,
I.e. around the rotation of cross axle 2-13, cause the increase of side axle shaft gear 2-10 rotating speed, and opposite side axle shaft gear 2-10 rotating speed
Reduction, both sides wheel rotates with different rotating speed, and now, the rotating speed that single wheel increases is equal to turning that opposite side wheel reduces
Speed.
When the road surface bad by road conditions, after single wheel loses and grabs ground, it is equivalently employed without resistance, the car of opposite side
Wheel is equivalent to be fixed on there, and what this time, the normal traveling of vehicle was played by differential mechanism is a retroaction, no longer needs
Want differential mechanism.The effect of differential lock is equivalent to one to be forced to intervene, and allows differential mechanism fail.At this moment, by work
Cylinder assembly 2-2 air pressure, drives fork 2-4, makes to slidably engage set 2-7 and locks into fixed engagement set 2-6 and differential carrier 2-11
Integrally, make differential mechanism lose differential action, thus can refuse to transfer on opposite side driving wheel all turning round, it is ensured that car load is just
Often travel.
This is taken turns limit differential lock vehicle bridge and is applicable to various engineering truck and various engineering-environment, and principle is simple, and running efficiency is high, gram
Take existing engineering truck back axle road surface handling capacity not strong, caused by the inefficient problem of property.
