Limitting casing 5f, limitting casing 5f are pressed on inner conical drogue 5d2 and transfer force to strut 5c by inner conical drogue 5d2 and carry supporting plate 5b again
On, because now, the power that limitting casing 5f is pressed on inner conical drogue 5d2 is smaller, so taper sleeve component 5d is also in self-locking state, finally
Supporting plate 5b is carried to be delivered on side frame composition 2 by bearing spring 5a.
When vehicle is loaded, bearing spring 5a compressions, return spring 5n compressions, bolster 1 is moved down, and pull bar 5g upper ends are relative
Bolster 1 rises, and the subtended angle between left crank throw 5h and right crank throw 5i becomes big, and spacing roller bearing 5m is moved upwards with respect to bolster 1, limitting casing
5f is in free state, and the center of gravity reduction of vehicle now just (must i.e. must by heightening the height of C.G. of vehicle from height-regulating device 5
Spacing in increase between supporting plate 5e and carrying supporting plate 5b), it is specific as follows：
When vehicle vibrates upwards, middle supporting plate 5e is moved downward with respect to bolster 1, is bored due to middle supporting plate 5e and between carrying supporting plate 5b
The self-locking action of set component 5d, carries supporting plate 5b and is also moved downward with respect to bolster 1, and strut 5c is also moved downward with respect to bolster 1；Car

5d drives limitting casing 5f also to move upwards in the presence of spring 5d3, until taper sleeve component 5d offsets with middle supporting plate 5e, vehicle exists
During second vibration downwards, because taper sleeve component 5d possesses taper auto-lock function, so taper sleeve component 5d cannot be moved downward, from
And supporting plate 5e also relative cannot carry supporting plate 5b and move downward in causing, but middle supporting plate 5e still may proceed to it is relative carry supporting plate 5b to
Upper motion, so circulation so that middle supporting plate 5e and the spacing carried between supporting plate 5b are increasing, until limitting casing 5f with
Spacing roller bearing 5m is offseted, and so far, automatic adjustment height process is completed.Now, the height of C.G. of vehicle just with empty wagons when vehicle center of gravity
It is highly consistent, so that the hitch between empty wagons, loaded vehicle is highly consistent, it is to avoid the generation of hitch fracture accident, it is ensured that
The safety of driving.
When vehicle is unloaded, because the height of now vehicle's center of gravity has been raised, so must be turned down by from height-regulating device 5
The height of C.G. (spacing in must reducing between supporting plate 5e and carrying supporting plate 5b) of vehicle, it is specific as follows：
During unloading, under bearing spring 5a rebound effects, carry during supporting plate 5b drives supporting plate 5e and limitting casing 5f together to
Upper motion, in upward motion process, because pull bar 5g upper ends maintain static, so the ascensional range of spacing roller bearing 5m is less than limit
The amplitude that position frame 5f rises, therefore, spacing roller bearing 5m is increasing to the downward oppressive force of limitting casing 5f, so so that spacing
Bulge loop 5f1 on frame 5f is also increasing to the downward oppressive force of inner conical drogue 5d2, until bulge loop 5f1 is outer by inner conical drogue 5d2 ejections
Simultaneously pressuring spring 5d3 is moved downward tapered sleeve 5d1, completes the unblock of taper sleeve component 5d, so that taper sleeve component 5d is relative carrying
Supporting plate 5b is moved downward, and then so that middle supporting plate 5e also carries supporting plate 5b and moves downward, so, middle supporting plate 5e and carrying support relatively
Spacing between plate 5b is got over and becomes smaller, until being returned to original state, so far, automatically turns down process completion.Now, the weight of vehicle
Height of C.G. when heart height just comes back to empty wagons, so that the hitch between empty wagons, loaded vehicle is highly consistent, it is to avoid car
The generation of hook fracture accident, it is ensured that the safety of driving.
The weight of vehicle is turned down by why explaining herein by the spacing between supporting plate 5e in regulation and carrying supporting plate 5b
The heart highly, specifically：In the case where car load is constant, the length of bearing spring 5a will not become the height for carrying supporting plate 5b
Will not become,
When the spacing between supporting plate 5e in regulation and carrying supporting plate 5b becomes big, middle supporting plate 5e can drive left crank throw 5h with the right side
Crank throw 5i is moved upwardly together, but because pull bar 5g upper ends will not move, so the subtended angle between left crank throw 5h and right crank throw 5i
Can diminish, the spacing between such upper roller 5j and bottom roller 5k will become big i.e. middle spacing meeting between supporting plate 5e and bolster 1
Become big, so, supporting plate 5e and the spacing carried between supporting plate 5b become big in not only adjusting, and middle supporting plate 5e and bolster 1 it
Between spacing also become greatly, therefore the height of bolster 1 has just uprised the height of C.G. of i.e. vehicle and has uprised；
When the spacing between supporting plate 5e in regulation and carrying supporting plate 5b becomes hour, left crank throw 5h can be in right crank throw 5i
Supporting plate 5e is moved downwardly together, but because pull bar 5g upper ends will not move, so the subtended angle between left crank throw 5h and right crank throw 5i
Can become big, the spacing meeting that the spacing between such upper roller 5j and bottom roller 5k will diminish between i.e. middle supporting plate 5e and bolster 1
Diminish, so, supporting plate 5e and the spacing carried between supporting plate 5b diminish in not only adjusting, and middle supporting plate 5e and bolster 1 it
Between spacing have also been smaller, therefore bolster 1 height with regard to step-down the i.e. height of C.G. step-down of vehicle.
