Principle of work of the present invention is as follows:
During empty wagons, the transmission of power is: most of load of vehicle is delivered to upper roller 5j by bolster 1, middle supporting plate 5e is delivered to again by bottom roller 5k, middle supporting plate 5e is delivered on strut 5c and carrying supporting plate 5b by taper sleeve component 5d again, finally carries supporting plate 5b and is delivered on side frame composition 2 by bearing spring 5a.In addition, the fraction load of vehicle oppresses limitting casing 5f by spacing roller bearing 5m, limitting casing 5f to be pressed in again on inner conical drogue 5d2 and to be delivered on strut 5c and carrying supporting plate 5b by inner conical drogue 5d2 by power, due to now, the power that limitting casing 5f is pressed on inner conical drogue 5d2 is less, so taper sleeve component 5d is also in self-locking state, finally carries supporting plate 5b and be delivered on side frame composition 2 by bearing spring 5a.
When vehicle loads, bearing spring 5a compresses, restoring spring 5n compresses, and bolster 1 moves down, and the relative bolster 1 in pull bar 5g upper end rises, subtended angle between left crank throw 5h and right crank throw 5i becomes large, spacing roller bearing 5m relative bolster 1 upward movement, limitting casing 5f is in free state, and the center of gravity of vehicle reduces, now just must pass through the height of gravitational center (spacing in namely must increasing between supporting plate 5e and carrying supporting plate 5b) heightening vehicle from height-regulating device 5, specific as follows:
When vehicle upwards vibrates, middle supporting plate 5e is relative, and bolster 1 moves downward, and due to the self-locking action of taper sleeve component 5d between middle supporting plate 5e and carrying supporting plate 5b, carrying supporting plate 5b also relative bolster 1 moves downward, and strut 5c also relative bolster 1 moves downward, when vehicle vibrates downwards, middle supporting plate 5e relatively carries supporting plate 5b upward movement under the effect of restoring spring 5n, simultaneously, taper sleeve component 5d drives limitting casing 5f also upward movement under the effect of spring 5d3, until taper sleeve component 5d and middle supporting plate 5e offsets, vehicle is when second time is vibrated downwards, because taper sleeve component 5d possesses taper auto-lock function, so taper sleeve component 5d cannot move downward, thus make middle supporting plate 5e also relatively cannot carry supporting plate 5b to move downward, but middle supporting plate 5e still can continue relatively to carry supporting plate 5b upward movement, circulation like this, thus make the spacing between middle supporting plate 5e and carrying supporting plate 5b increasing, until limitting casing 5f and spacing roller bearing 5m offsets, so far, automatic adjustment height process completes.Now, the height of gravitational center of vehicle is just consistent with the height of gravitational center of vehicle during empty wagons, thus makes the hitch height between empty wagons, loaded vehicle consistent, avoids the generation of hitch fracture accident, ensure that the safety of driving.
During vehicle unloading, because the height of now vehicle's center of gravity is raised, so must by turning down the height of gravitational center (in namely must reducing supporting plate 5e and the spacing that carries between supporting plate 5b) of vehicle from height-regulating device 5, specific as follows:
During unloading, under bearing spring 5a rebound action, supporting plate 5e upward movement together with limitting casing 5f during carrying supporting plate 5b drives, in upward movement process, because pull bar 5g upper end maintains static, so the ascensional range of spacing roller bearing 5m is less than the amplitude that limitting casing 5f rises, therefore, the downward oppressive force of spacing roller bearing 5m to limitting casing 5f is increasing, like this, make the downward oppressive force of the bulge loop 5f1 on limitting casing 5f to inner conical drogue 5d2 also increasing, until inner conical drogue 5d2 is ejected external conical sleeve 5d1 to bulge loop 5f1 and pressuring spring 5d3 moves downward, complete the unblock of taper sleeve component 5d, thus make taper sleeve component 5d relatively carry supporting plate 5b to move downward, and then make middle supporting plate 5e also relatively carry supporting plate 5b to move downward, like this, spacing between middle supporting plate 5e and carrying supporting plate 5b becomes less and less, until be returned to initial condition, so far, automatically process of turning down completes.Now, the height of gravitational center of vehicle just comes back to height of gravitational center during empty wagons, thus makes the hitch height between empty wagons, loaded vehicle consistent, avoids the generation of hitch fracture accident, ensure that the safety of driving.
Be interpreted as at this height of gravitational center what spacing passed through in adjustment between supporting plate 5e and carrying supporting plate 5b can turn down vehicle, particularly: when car load is constant, the length of bearing spring 5a can not become the height namely carrying supporting plate 5b and can not become,
When supporting plate 5e in regulating and the spacing between carrying supporting plate 5b become large, middle supporting plate 5e can drive left crank throw 5h upward movement together with right crank throw 5i, but because pull bar 5g upper end can not be moved, so the subtended angle between left crank throw 5h and right crank throw 5i can diminish, spacing between such upper roller 5j and bottom roller 5k will become large i.e. middle spacing between supporting plate 5e and bolster 1 can become large, like this, spacing in not only regulating between supporting plate 5e and carrying supporting plate 5b becomes large, and the spacing between middle supporting plate 5e and bolster 1 has also become greatly, therefore the height of bolster 1 has uprised with regard to the height of gravitational center having uprised i.e. vehicle,
As supporting plate 5e in regulating and the pitch smaller between carrying supporting plate 5b, left crank throw 5h can move downward with right crank throw 5i together with middle supporting plate 5e, but because pull bar 5g upper end can not be moved, so the subtended angle between left crank throw 5h and right crank throw 5i can become large, the spacing that spacing between such upper roller 5j and bottom roller 5k will diminish namely between supporting plate 5e and bolster 1 can diminish, like this, pitch smaller in not only regulating between supporting plate 5e and carrying supporting plate 5b, and the spacing between middle supporting plate 5e and bolster 1 have also been smaller, therefore the height of gravitational center step-down of the height of the bolster 1 i.e. vehicle with regard to step-down.
The present invention coordinates the automatic increase that can realize carrying spacing between supporting plate 5b and middle supporting plate 5e by taper sleeve component 5d and restoring spring 5n's, thus achieves the automatic adjustment height of bolster 1 height; And coordinate the automatic reduction that can realize carrying spacing between supporting plate 5b and middle supporting plate 5e by taper sleeve component 5d and limitting casing 5f, thus achieve automatically turning down of bolster 1 height, structure is simple and improvement cost is low; By the taper auto-lock function between external conical sleeve 5d1 and inner conical drogue 5d2, the unidirectional upward movement of taper sleeve component 5d can be realized; The step 5d4 added facilitates the location and installation of middle supporting plate 5e, simultaneously also for supporting plate 5e end face in guarantee provides condition lower than limitting casing 5f bottom surface; The sleeve 5e1 added not only can play the effect of supporting plate 5e in location and installation, but also can play the effect of supporting plate 5e in guiding; The bearing spring mounting cup 5b1 added can prevent bearing spring 5a to be shifted in elastic deformation effectively; The restoring spring mounting cup 5e2 added can prevent restoring spring 5n to be shifted in elastic deformation effectively; The guide groove 5e3 added can prevent pull bar 5g from the process with vehicle up-down vibration, lateral deviation occurring; By in a row being arranged by upper roller 5j and bottom roller 5k, the power on such bolster 1 can be delivered to below by which better upper roller 5j and bottom roller 5k.
