At present, both at home and abroad roller bearing adapter stabilizer bar generally adopts three-major-items formula bogie truck, and more the bolster of this bogie truck and connecting device between the bogie side frame adopt and become friction or the wedge that often rubs and add the pillow spring and is connected, with realization carrying, power transmission and vibration-damping function.But because the existence of friction pair,, thereby cause the operation stability of vehicle to descend along with the diamond resistant rigidity of the increase vehicle bogie side frame of abrasion will reduce greatly.In order to improve the problem that existing bogie truck exists, realize not having abrasion, the novel connecting device between research and development bogie side frame and the bolster has crucial meaning with effective raising vehicle operating stability.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of performance that can effectively improve bogie truck, guarantees the bolster and the bogie side frame connecting device of vehicle operating safety.
For achieving the above object, the utility model is taked following technical scheme: a kind of bolster and bogie side frame connecting device is characterized in that: it comprises bolster Connection Block, elastic ball joint, connects guide pillar, fastening stud and bogie side frame guide pillar Connection Block; Described bolster Connection Block is the steel profiled piece, and it comprises that a rectangle connects seat board, the central bottom that described rectangle connects seat board be provided with one with bolster bonded assembly Long Circle bearing, the top, two ends that described rectangle connects seat board is provided with a tubular bearing; Press-fit a described elastic ball joint in two tubular bearings of described bolster Connection Block respectively, and described tubular bearing and described elastic ball joint are interference fit; Described connection guide pillar is the cylindrical structural that the middle part is provided with a delineation position step, and its bottom is provided with a screw that matches with described fastening stud; The bottom of described connection guide pillar is plugged in the described elastic ball joint, and realizes described elastic ball joint and the connection that is connected guide pillar by the positioning step of described connection guide pillar with described fastening stud; Described bogie side frame guide pillar Connection Block is the circular lid-like of being made up of end cap and seat body, and the top of described connection guide pillar is plugged in the seat body of described bogie side frame guide pillar Connection Block.
Described elastic ball joint is the globoid structure that is formed by overcoat, rubber layer and the sulfuration of interior cover, and described overcoat is surrounded by the uniform burst of some block sizes.
Studding with the abrasion cover in the seat body of described bogie side frame guide pillar Connection Block cooperates with the described guide pillar that is connected.
Evenly be provided with several and bogie side frame bonded assembly bolt hole on the end cap of described bogie side frame guide pillar Connection Block.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is vertical does not retrain vertical move between bolster and the bogie side frame, radial rigidity by the elastic ball joint provides vertical, transverse elasticity between bolster and the bogie side frame to locate, the elastic torsion rigidity of nodding, sidewinder and shake the head between bolster and the bogie side frame is provided simultaneously, not only help bringing into play the ability that three piece truck adapts to circuit, also help and suppress bogie side frame generation diamonding, thereby improved the operation stability of vehicle, guaranteed the safe in operation of vehicle.2, stud with the abrasion cover in the seat body of the utility model bogie side frame guide pillar Connection Block and be connected the guide pillar cooperation, thereby avoided bogie side frame guide pillar Connection Block and be connected guide pillar transition abrasion.The utility model can be widely used in the bolster and bogie side frame of railway truck three-major-items formula bogie truck.
Description of drawings
Fig. 1 is a cut-away view of the present utility model
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises bolster Connection Block 1, elastic ball joint 2, connects guide pillar 3, fastening stud 4 and bogie side frame guide pillar Connection Block 5.
