Abstract
The utility model relates to a bogie of a wagon which comprises wheel set assemblies, side frame assemblies, swing bolster assemblies, vibration dampers, adapters, bearing springs, rolling bearings and gear keys. The bogie is characterized in that the vibration dampers are inclined wedge vibration dampers; each inclined wedge vibration damper includes a hollow inclined wedge and a control spring; the inclined wedge vibration dampers are arranged in the recessed position of the swing bolsters and between the swing bolster assemblies; the control springs comprise inner control springs and outer control springs; two normal-contact elastic side bearers are mounted on the swing bolster assemblies; and a unit braking device is arranged between the side frame assemblies. By adopting the structure, the bogie not only has stable resistance force for vibration damping, larger diamond resistant rigidity and excellent dynamic performance, but also is simple in structure and convenient to overhaul.
Description
Technical field
The utility model relates to a kind of bogie truck, particularly a kind of railway goods train bogie.
Background technology
Bogie truck is the following part of lorry body.Three-major-items formula bogie truck is to use one of maximum bogie truck type in the world, and the characteristics of this type bogie truck are that simple in structure, heavily loaded ability is strong, but owing to do not have direct connection between bolster and the bogie side frame, cause it loosely organized, diamond resistant rigidity is low, easy snakelike unstability, and running velocity is generally lower.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of railway goods train bogie stable, simple in structure.
For solving the problems of the technologies described above, the utility model comprises that wheel is to composition, bogie side frame composition, bolster composition, shock attenuation unit, adapter, bearing spring, antifriction-bearing box, block key, it is characterized in that, described shock attenuation unit is an oblique wedge vibration damper, oblique wedge vibration damper is made up of wedge and controlling spring that a centre hollows out, be installed in bolster and form between recessed position and the bogie side frame composition, described controlling spring comprises spring in the control, the outer spring of control.
In the such scheme, described bolster is equipped with two The Constant-Contact Resilient Side Bearings on forming.
In the such scheme, described bogie side frame is provided with unit brake device between forming.
Preferably, described bogie side frame is formed and is also comprised the drawing strickle guide wearing plate, and described drawing strickle guide wearing plate is a hatch frame, and the hatch frame top dimension is greater than the bogie side frame width, and the undersized at hatch frame middle part is in the bogie side frame width; Described bogie side frame is installed on the drawing strickle guide wearing plate, and described drawing strickle guide wearing plate is installed in the adapter end face.
More preferred, described bolster composition is provided with the self-locking center pin, and described self-locking center pin comprises center pin, last lock pin, following lock pin, spacing ring, lock ring, flap seat; Described center pin two ends vertical center line has two pin-and-holes, and the top pin-and-hole is circular hole or slotted hole, and the bottom pin-and-hole is a slotted hole; The described lock pin of going up passes the top pin-and-hole, and last lock pin two ends are provided with spacing ring; Described center pin passes car body body center plate hole and bolster cartridge hole; Described bolster cartridge basifacial web is provided with pin-and-hole; Described lock pin down passes bottom pin-and-hole and bolster web pin-and-hole, and following lock pin one end is provided with lock ring, and the bolster web is equipped with flap seat near lock ring one side.
The utility model not only has stable vibration damping resistance, bigger diamond resistant rigidity, good dynamic performance owing to adopted said structure, and is simultaneously simple in structure, easy access.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a plan structure scheme drawing of the present utility model;
Fig. 3 is an oblique wedge vibration damper structural representation of the present utility model.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprise wheel to form 1, antifriction-bearing box 2-, block key 3--, oblique wedge vibration damper 4--, self-locking center pin 5, bolster form 6, bearing spring 7, bogie side frame form 8, drawing strickle guide wearing plate 9, The Constant-Contact Resilient Side Bearings 10, unit brake device 11.Oblique wedge vibration damper 4 is made up of wedge 12 and controlling spring that a centre hollows out, is installed in bolster and forms between 6 recessed position and the bogie side frame composition 8, and described controlling spring comprises spring 13 in the control, the outer spring 14 of control.Form 8 at bogie side frame unit brake device 11 also is installed.Adopt oblique wedge vibration damper 4, for bogie truck provides enough diamond resistant rigidities, the serpentine locomotion of control vehicle, and have good curving performance, and stable friction damping resistance can be provided, failure-free guarantees the vibration of vehicle performance.Adopt unit brake device 11, guarantee the vehicle braked performance, the longitudinal impact property when improving car brakeing.
In order to suppress the hunting motion of shaking the head of car body, constraint car body rolling is formed installation The Constant-Contact Resilient Side Bearings 10 on 6 at truck bolster.In the vehicle operating process, body side bearing and the The Constant-Contact Resilient Side Bearings on the bolster 10 on the car body are in normal contact condition.The Constant-Contact Resilient Side Bearings 10 is vertically contacting for no gap with truck bolster with truck body, has realized vertical, vertical elasticity location, thereby has improved the vehicle dynamics performance, has improved the vehicle operating quality.Adopt self-locking center pin 5, can under situations such as vehicle lifting, prevent to break away between car body and the bogie truck.Adopt drawing strickle guide wearing plate 9, can solve bogie side frame abrasion problem, can realize that changing part repaiies.
The transmittance process of the load on the truck body is: cartridge-bolster-bearing spring-bogie side frame-adapter-bearing-axletree-wheel-rail.
It should be noted last that, the above specific embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
