Abstract
The utility model relates to a single-pull rod traction device, the single-pull rod traction connection form is adopted, and the simplified and lightweight traction connection is utilized for effectively inhibiting the sliding at the junction of a traction support seat and a traction pull rod, thereby realizing the purpose of improving the load transferring driving force and the steering traction on a vehicle body. The single-pull rod traction device mainly comprises the pull rod, one end of the pull rod is connected with a traction rod support seat at the inner side of a truss of a steering frame through a rubber node, and the other end thereof is connected with the traction rod support seat below the vehicle body through the rubber node; and a positioning shaft penetrates through and is fastened at the traction rod support seat through a shaft sleeve and a bolt in the rubber nodes at two side ends of the pull rod. The single-pull rod traction device is simple in structure, and further has the advantages of good cushioning effect, high safety performance and the like on the base of the characteristics of light weight, high strength and the like.
Description
Technical field
The utility model is the bogie truck draw gear that is applied to guideway vehicle, belongs to mechanical manufacturing field.
Background technology
High-speed cruising guideway vehicle speed per hour has generally reached more than 200 kilometers at present, as the bogie truck of important support with the traction directional tagging, it has mainly been realized to the car body transmission of drive force and turned to traction on rectilinear orbit or bend, has promptly realized loading transfer under the prerequisite of bearing its top car body weight.
Existing draw gear has multiple structure, and comparatively generally the pull bar hitch structure of Cai Yonging, operation speed per hour big in the car body load-carrying is uncommon on the high speed train faster.Tracing it to its cause is to be easy to take place in the junction of traction bearing and drawing pull bar slide mutually and rotate, thereby directly has influence on the dynamic performance of guideway vehicle.
Therefore how to utilize existing draw gear package assembly further to improve transmission performance at deadlight load, be the technical barrier that presses for solution always.
The utility model content
Simplex pull rod draw gear described in the utility model, its design goal is to address the above problem and takes the traction type of attachment of simplex pull rod, utilize simplification, weight-saving traction to connect the slip that suppresses to draw bearing and drawing pull bar junction effectively, thereby realize improving at deadlight load transmission of drive force and the purpose that turns to traction.
For realizing above-mentioned design goal, described simplex pull rod draw gear mainly comprises:
One pull bar,
One end of pull bar is connected in the draw bar bearing of truck frame inboard by rubber nodal point,
The other end of pull bar is connected in the draw bar bearing of car body below by rubber nodal point.
As above-mentioned basic scheme, the simplex pull rod draw gear to locomotive vertical, vertical with different rigidity Design laterally is provided, optimized the dynamic performance of high speed train.
At the rubber nodal point that the pull bar two side ends press-fits, can play significantly laterally and the buffer action on vertical, solved vibration and the rotation of pull bar effectively with traction bearing junction.
Be the location of further improving the pull bar two ends and propulsive effort, the transmission effect that pulls round, in the rubber nodal point of pull bar two side ends, fix shaft is anchored on the draw bar bearing by axle sleeve and bolt-through.
In sum, the utility model simplex pull rod draw gear has the following advantages:
1, this type of simplex pull rod draw gear simple in structure, on basis, also have good buffer effect, safety performance advantages of higher concurrently with characteristics such as in light weight, intensity height.
2, can resist the slip of traction bearing and drawing pull bar junction effectively, obviously reduce transfer torque, thereby raising is to deadlight load transmission of drive force, the effect that pulls round.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described further.
Fig. 1 is the structural representation of described simplex pull rod draw gear;
Fig. 2 is the side schematic view of Fig. 1;
Fig. 3 is bowing to scheme drawing of Fig. 1;
As shown in Figure 1 to Figure 3, pull bar 1, fix shaft 2, yielding rubber 3, axle sleeve 4, bolt 5, draw bar bearing 20, draw bar bearing 30.
The specific embodiment
Embodiment 1, as shown in Figure 1 to Figure 3, a kind of simplex pull rod draw gear that is applied to guideway vehicle, it mainly has a pull bar 1, pull bar 1 one ends are connected in the draw bar bearing 20 of truck frame inboard by rubber nodal point, and the other end of pull bar 1 is connected in the draw bar bearing 30 of car body below by rubber nodal point.
Draw bar bearing 20 is directly welded in the truck frame inboard, and draw bar bearing 30 is directly welded in the car body below.
The rubber nodal point of pull bar 1 two side ends, its 2 fix shafts 2 run through by axle sleeve 4 and bolt 5 respectively and are anchored on draw bar bearing 20 and draw bar bearing 30.
