Abstract
The utility model relates to a central traction apparatus of a railway vehicle, wherein a limit structure which is opposite to a frame is arranged on a traction beam, thereby preventing a vehicle body from going up unusually after excessive aeration of an air spring, avoiding overturn of the vehicle through vertical limit and guaranteeing the safety of passengers. The central traction apparatus of the railway vehicle comprises a traction pin connected with the vehicle body, a traction beam vertically connected with the traction pin and a traction rod connected between a truck frame and the traction beam, wherein a base plate and a press plate are installed on the upper end face of the traction beam by fastening bolts; the vertical distance between the top of the press plate and the bottom of the truck frame is A; when the excessive aeration of the air spring is caused, and the vehicle body goes up unusually in the vertical direction, the top of the press plate can tightly push against the bottom of the frame to realize the relative limit, so that downward limit force is exerted to the vehicle body by the frame to prevent the vehicle from overturning.
Description
Technical field
The utility model relates to the structural development of the central draw gear of a kind of guideway vehicle, belongs to mechanical manufacturing field.
Background technology
The guideway vehicle speed per hour of present domestic main line railway reached 380 kilometers and more than, correspondingly require vehicle to have comparatively outstanding transmission of power and design with safety protection structure.
Vehicle is in the process of running at high speed, owing to cross the contrast of bent angle radian, deadlight load situation of change, existing central draw gear has the deficiency in many defectives and the function design.
Such as when air bellow overcharges, will cause that directly car body produces the abnormal ascending phenomenon on vertical, existing vehicle lacks correspondence ground position limiting structure.More just be easy to cause that vehicle topples if car body rises, thereby directly have influence on passenger safety.
Need carry out the car load lifting when vehicle overhauls, promptly car body and bogie truck are lifted away from track simultaneously.Existing common operation is the separation type lifting, still can not take simple means to realize the car load lifting of car body and bogie truck.
Crossing in the bent angle process at a high speed, there is certain torsiversion malposition between car body and the bogie truck in addition, needs increase that the spacing measure of cross motion is arranged for avoiding car body that deflection exceedingly takes place.
In view of this special present patent application that proposes.
The utility model content
The central draw gear of guideway vehicle described in the utility model, its design goal is to solve the problem of above-mentioned prior art existence and the position limiting structure relative with framework is set on draw beam, with the car body abnormal ascending that prevents to cause after air bellow from overcharging, by vertical spacing to prevent that vehicle from toppling, guaranteeing passenger safety.
Another design goal is to realize the vertical adjustable gaps between draw beam and the framework, the purpose of integral lifting when being used to reach car inspection and maintenance.
Design goal also is, adjusts the vertical height of draw beam upper surface after being implemented in wheel and wearing away neatly, and the step that simplifies the operation also need not to lift car and handles.
For realizing above-mentioned design goal, the central draw gear of described guideway vehicle mainly includes:
With car body bonded assembly towing pin,, and be connected drawing pull bar between truck frame and the draw beam with the vertical bonded assembly draw beam of towing pin.
The difference with the prior art part is, in the upper surface of draw beam, by binding bolt backing plate and pressing plate is installed;
Vertical distance between the top of pressing plate and the bottom of truck frame is A.
As above-mentioned basic scheme feature, be applied to the central draw gear of guideway vehicle, can realize the transmission of longitudinal direction of car tractive force simultaneously and prevent that air bellow from overcharging and carry out functions such as integral lifting.
When air bellow overcharged, car body produced vertical abnormal ascending, and can be closely against the framework bottom by the pressing plate top and be achieved relative limit this moment, promptly applies downward position-limiting action power by framework to car body and topple to prevent vehicle.
When car inspection and maintenance, in turn drive towing pin, draw beam by the lifting car body, when the top of pressing plate is closely against framework when bottom, framework upwards can be lifted away from and the bogie truck of realizing slinging, car load lifting.
For improving the anti-overcharge performance with integral lifting of empty spring further, be between draw beam and backing plate, adjusting pad to be arranged liner, promptly by the thickness of regulating adjusting pad and the occurrence that quantity is come spacing A at the refinement adjustment mode of spacing A.
At the safety precaution of car body excessive deflection, the refinement improvement project that can take is when realizing crossing bent angle at a high speed, on truck frame, be provided with a pair of horizontal backstop opposite to each other with draw beam.
As above content, the advantage that described guideway vehicle central authorities draw gear has is:
1, when implementing the transmission of longitudinal traction power, realize preventing the safety precaution that the sky spring overcharges, can simplify the bogie truck integral structure, help reducing complete vehicle weight and improve Vehicle Speed.
2, can prevent the car body abnormal ascending effectively and avoid vehicle to topple, guarantee passenger safety.
3, but the vertical gap flexible between draw beam and the framework realizes the vehicle integral lifting easily.
4, after wheel wears away, can adjust the vertical height of draw beam upper cover plate effectively, need not to change bolt and handle with lifting car, adjust comparatively easy.
Description of drawings
Now in conjunction with the following drawings the utility model is described further
Fig. 1 is the scheme drawing of the central draw gear of described guideway vehicle;
Fig. 2 is the side schematic view of Fig. 1;
Fig. 3 is the I portion enlarged diagram among Fig. 2;
Fig. 4 is the contrast scheme drawing of adjusting with respect to Fig. 3;
As shown in Figures 1 to 4, towing pin 1, draw beam 2, framework 3, backing plate 4, pressing plate 5, adjusting pad 6, binding bolt 7, drawing pull bar 8, horizontal backstop 9.
The specific embodiment
Embodiment 1, and as shown in Figures 1 to 4, the central draw gear of described guideway vehicle mainly includes:
With car body (not shown) bonded assembly towing pin 1,
Be connected the drawing pull bar 8 between truck frame 3 and the draw beam 2.
In the upper surface of draw beam 2, by binding bolt 7 backing plate 4 and pressing plate 5 are installed, liner has adjusting pad 6 between draw beam 2 and backing plate 4.
Vertical distance between the bottom of the top of pressing plate 5 and truck frame 3 is A.
On truck frame 3, with draw beam 2 be provided with a pair of horizontal backstop 9 opposite to each other.
Described guideway vehicle central authorities draw gear, can realize simultaneously longitudinal traction power transmission, cross spacing, prevent that the sky spring from overcharging and function such as integral lifting.
Can realize the transmission of longitudinal traction power by towing pin 1, draw beam 2, drawing pull bar 8 and framework 3.
Realize spacing to the cross-car motion by towing pin 1 and horizontal backstop 9.
When air bellow overcharged, car body produced abnormal ascending, and can be closely against framework 3 bottoms by pressing plate 5 tops and be achieved relative limit this moment, promptly applies downward position-limiting action power by framework 3 to car body and topple to prevent vehicle.
Car load when lifting and lifting car body at first, car body drives towing pin 1, and towing pin 1 drives draw beam 2, thus draw beam 2 drives frameworks 3 bogie truck of slinging, to realize the car load lifting.
