Guideway vehicle moves on underground, ground and elevated line, often contains the materials such as sulfuric acid, sulphur dioxide, acid rain, ozone, salt fog in air.Along with travelling of vehicle, very easily form water droplet or greasy dirt and penetrate in the central traction apparatus that does not add dust keeper, cause corrosion, it is greatly unfavorable that the maintenance to the later stage and the in-use performance of parts have brought.
Utility model content
The utility model main purpose is to address the above problem and is not enough, provides a kind of simple in structure, can realize the rail vehicle truck central traction apparatus dustproof construction of excellent sealing effect.
For achieving the above object, the technical solution of the utility model is:
A kind of rail vehicle truck central traction apparatus dustproof construction, comprise framework, towing pin, draw beam, top at the kingpin hole of described draw beam arranges a circle dust ring along border, described towing pin is pressed on described dust ring, and described dust ring is at least made up of one deck rubber layer.
Further, described dust ring also comprises one deck nylon layer, and described rubber layer is enclosed in the skin of described nylon layer, and described nylon layer and the sulfuration of described rubber layer are structure as a whole.
Further, described dust ring is directly placed on described draw beam and utilizes the weight of described towing pin to be fixed.
Further, the nylon layer of described dust ring and the section form of rubber layer are inverted L-shaped.
To sum up content, rail vehicle truck central traction apparatus dustproof construction described in the utility model, has optimized the structure of bogie truck, and project organization is simple, Assembly &Disassembly is convenient, by the deadweight of vehicle, towing pin is pressed in draw beam to the rubber on extruding dustproof construction, can realize sealing effectiveness, prevent that greasy dirt, water droplet from penetrating in draw beam, avoid causing corrosion, reduced automotive servicing cost.
Accompanying drawing explanation
Fig. 1 is the utility model central traction apparatus structural representation;
Fig. 2 is the utility model dustproof construction cutaway view.
As depicted in figs. 1 and 2, dust ring 1, towing pin 2, draw beam 3, drawing pull bar 4, car body 5, bolt 6, central pin bush 7, closure plate 8, bolt 9, kingpin hole 10, nylon layer 11, rubber layer 12.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Figure 1, the utility model provides a kind of rail vehicle truck central traction apparatus dustproof construction, and the central traction apparatus that forwards frame comprises framework (not shown), towing pin 2, draw beam 3, drawing pull bar 4 etc.
Framework is generally made up of two curb girders, two crossbeams and two gate beams, two crossbeams are parallel to each other and are vertical with curb girder, the two ends of two crossbeams are fixed on the curb girder of both sides, between two crossbeams, gate beam is set, gate beam and beam vertical, the two ends of gate beam are fixed on the crossbeam of both sides, and gate beam can arrange two, and 2 of towing pins pass by two crossbeams and two spaces that gate beam surrounds.Gate beam also can only arrange one, offers a through hole in the centre of gate beam, and towing pin 2 arranges through this through hole.
The top of towing pin 2 is fixedly connected on car body 5 by multiple bolts 6,3 of drawing pull bar 4 and draw beams are arranged on the bottom position of towing pin 2, drawing pull bar 4 is symmetrically arranged with two, one end of drawing pull bar 4 is connected with framework, the other end of drawing pull bar 4 is connected with draw beam 3 by drawing pull bar seat, on draw beam 3, be provided with kingpin hole 10, central pin bush 7 is installed in kingpin hole 10, the bottom of towing pin 2 is through central pin bush 7, with bolt 9, draw beam 3 is connected with towing pin 2 with closure plate 8.Car load lifting, when lifting car body 5, car body 5 drives towing pin 2, and towing pin 2 drives draw beam 3, and draw beam 3 drives framework, thereby lifts by crane whole bogie truck, realizes car load lifting.
Vehicle is in operational process, motor driven systems driven wheel, to rotating, is passed to framework by single stage suspension device by tractive force, then passes to towing pin 2 by drawing pull bar 4, draw beam 3, towing pin 2 is fixedly connected with car body 5, finally tractive force is passed to car body 5.When braking, by the brake disc on brake equipment clamping wheel, braking force is passed to wheel right, takes turns by single stage suspension device, braking force being passed to framework, then pass to towing pin 2 by drawing pull bar 4, draw beam 3, finally braking force is passed to car body 5.
As shown in Figure 1, in the present embodiment, at the top of the kingpin hole 10 of draw beam 3, a circle dust ring 1 is set along border.Dust ring 1 is at least made up of one deck rubber layer 12, as shown in Figure 2, in order to strengthen the bulk strength of dust ring 1, make it meet the various conditions of vehicle operating, the present embodiment, dust ring 1 is made up of rubber layer 12 and nylon layer 11 double-layer structures, and rubber layer 12 is enclosed in the skin of nylon layer 11, and rubber layer 12 and nylon layer 11 are sulfided into integrative-structure.Dust ring 1 is directly placed on draw beam 3, utilizes the weight of towing pin 2 to be fixed.
In order to coordinate the structure at draw beam 3 kingpin hole 10 tops, the nylon layer 11 of dust ring 1 and the section form of rubber layer 12 are inverted L-shaped, and nylon layer 11 is closely fixed on the corner at kingpin hole 10 tops.The shape of the shape of the outside face of rubber layer 12 and towing pin 2 matches, towing pin 2 be fit into the kingpin hole 10 of draw beam 3 interior after, towing pin 2 relies on the rubber layer 12 on weight extruding dust ring 1 upper strata of himself, and then realize the sealing between draw beam 3 and towing pin 2, in vehicle operating, prevent that greasy dirt, water droplet from penetrating in draw beam 3, avoid causing corrosion, also reduced automotive servicing cost.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not depart from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
