Abstract
The utility model relates to a simplex pull rod type low-position traction device. By means of simplified and light-weight tractive connection, the sliding at the joint between a central pin and a tractive pull rod can be effectively inhibited, so that drive and turning transmissions to a body can be enhanced. Through a bolt, a horizontal simplex pull rod is connected with the lower end of the central pin mounted on the underside of the body, and the other end of the simplex pull rod is connected with a bogie structure. The lower end of the central pin, which is connected with the simplex pull rod, is provided with a longitudinally extended cambered part. Cushion rubbers are respectively pressed on both ends of the simplex pull rod. The simplex pull rod type traction device, which has the advantages of simple structure and light weight, can effectively prevent the nodding motion of the body and the bogie structure, and can prevent the abnormal rise of the body.
Description
Technical field
The utility model relates to a kind of bogie truck draw gear of high-speed track vehicle, belongs to mechanical manufacturing field.
Background technology
The motor train unit speed per hour of place in operation has generally reached more than 200 kilometers at present, and the bogie truck of this type of hot-short is used for to car body transmission driving and turns to tractive force, and the weight of bearing its top car body.The parts of realizing loading transfer mainly adopt Tiebar structure.
Existing drawing pull bar structure has multiple, and is big and in the junction of center pin and drawing pull bar slip mutually takes place easily and directly have influence on the dynamic performance of guideway vehicle for the car body load-carrying.
Therefore, the design of the structure and parameter of existing draw gear coupling also needs further to improve the delivery request for deadlight load on the basis of satisfying detail assembly between bogie truck and the car body.
The utility model content
The utility model provides a kind of simplex pull rod formula low level draw gear, its design goal is to address the above problem and adopts simplex pull rod formula draw gear, with by simplifying and the weight-saving traction is connected the slip that suppresses center pin and drawing pull bar junction effectively, raising is to the driving of car body and turn to transmission.
For realizing above-mentioned design goal, described simplex pull rod formula low level draw gear mainly has:
In the center pin bottom that is installed on below the car body, by bolted connection one horizontal simplex pull rod, the other end of simplex pull rod connects truck frame.
For improving by center pin to car body transmission driving and turning force, the moment of torsion that also center pin bears when being reduced in guideway vehicle through bent angle simultaneously, can take following improvement project:
Described center pin connects the bottom of simplex pull rod, has an arc-shaped bend portion of vertically stretching out.
For further reducing the vibration of simplex pull rod and framework, center pin junction, be pressed with yielding rubber respectively at the both ends of single connecting rod.
As mentioned above, the advantage that has of the utility model simplex pull rod formula low level draw gear is:
1, simplex pull rod formula draw gear is simple in structure, in light weight, prevents from effectively to produce the motion of nodding between car body and the truck frame, and can prevent the car body abnormal ascending.
2, the slip of center pin and drawing pull bar junction is resisted effectively.
3, improved to car body transmission driving and turning force, reduced the transmission power moment of torsion that center pin bears.
Description of drawings
Now in conjunction with the following drawings the utility model is described further.
Fig. 1 is the structural representation of simplex pull rod formula low level draw gear;
As shown in Figure 1, center pin 2, arc-shaped bend portion 21, simplex pull rod 3, bolt 4, yielding rubber 5.The specific embodiment
Embodiment 1, as shown in Figure 1, below the car body (not shown) of guideway vehicle center pin 2 is installed, and center pin 2 bottoms connect a horizontal simplex pull rod 3 by bolt 4, and center pin 2 has an arc-shaped bend portion 21 of vertically stretching out.
The other end of simplex pull rod 3 connects the truck frame (not shown).
At the both ends of single connecting rod 3, be pressed with yielding rubber 5 respectively.
Wherein, center pin 2 and simplex pull rod 3 adopt the thin-walled weather-resistant steel plate to be welded respectively.
Adopt above-mentioned simplex pull rod low level draw gear, can realize the loading transfer between car body and the truck frame, suppress the abnormal ascending amount of bogie truck height of gravitational center by the simplex pull rod 3 of low level setting, and can prevent to produce between car body and the truck frame motion of nodding effectively.
Claims (3)
1, a kind of simplex pull rod formula low level draw gear is characterized in that: in center pin (2) bottom that is installed on below the car body, connect a horizontal simplex pull rod (3) by bolt (4), the other end of simplex pull rod (3) connects truck frame.
