Description
Technical field
The present invention relates to a kind of connecting device, particularly about a kind of bolster and bogie side frame connecting device that is used for railway truck three-major-items formula bogie truck.
Background technology
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
To the problems referred to above, the purpose of this invention is to provide a kind of performance that can effectively improve bogie truck, guarantee the bolster and the bogie side frame connecting device of vehicle operating safety.
For realizing above-mentioned purpose, the present invention takes 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; Said bolster Connection Block is the steel profiled piece, and it comprises that a rectangle connects seat board, the central bottom that said rectangle connects seat board be provided with one with bolster bonded assembly Long Circle bearing, the top, two ends that said rectangle connects seat board is provided with a tubular bearing; Press-fit a said elastic ball joint in two tubular bearings of said bolster Connection Block respectively, and said tubular bearing and said elastic ball joint are interference fit; Said connection guide pillar is the cylindrical structural that the middle part is provided with a delineation position step, and its bottom is provided with the screw that matches with said fastening stud; The bottom of said connection guide pillar is plugged in the said elastic ball joint, and realizes said elastic ball joint and the connection that is connected guide pillar through the positioning step of said connection guide pillar with said fastening stud; Said 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 said connection guide pillar is plugged in the seat body of said bogie side frame guide pillar Connection Block.
Said elastic ball joint is the globoid structure that is formed by overcoat, rubber layer and the sulfuration of interior cover, and said overcoat is surrounded by the uniform burst of some block sizes.
Studding with the abrasion cover in the seat body of said bogie side frame guide pillar Connection Block cooperates with the said guide pillar that is connected.
Evenly be provided with several and bogie side frame bonded assembly bolt hole on the end cap of said bogie side frame guide pillar Connection Block.
The present invention is owing to take above technical scheme; It has the following advantages: 1, the present invention is vertical does not retrain vertical move between bolster and the bogie side frame; Radial rigidity through the elastic ball joint provides vertical, transverse elasticity location between bolster and the bogie side frame; The elastic torsion rigidity of nodding, sidewinder and shake the head between bolster and the bogie side frame is provided simultaneously, not only helps 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 bogie side frame guide pillar Connection Block of the present invention and be connected the guide pillar cooperation, thereby avoided bogie side frame guide pillar Connection Block and be connected guide pillar transition abrasion.The present invention 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 invention
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is carried out detailed description.
As shown in Figure 1, the present invention includes bolster Connection Block 1, elastic ball joint 2, connect guide pillar 3, fastening stud 4 and bogie side frame guide pillar Connection Block 5.
Bolster Connection Block 1 is the steel profiled piece; It comprises that a rectangle connects seat board 11; The central bottom that rectangle connects seat board 11 be provided with one with bolster bonded assembly Long Circle bearing 12, the top, two ends that rectangle connects seat board 11 be provided with one with elastic ball joint 2 bonded assembly tubular bearings 13.
Connect guide pillar 3 and be provided with the cylindrical structural of a delineation position step 31, and be provided with the screw 32 that matches with fastening stud 4 bottom it for the middle part.The bottom that connects guide pillar 3 is plugged in the interior cover 23 in elastic ball joint 2, and realizes elastic ball joint 2 and the connection that is connected guide pillar 3 through the positioning step 31 that connects guide pillar 3 with fastening stud 4.
Bogie side frame guide pillar Connection Block 5 is the circular lid-like of being made up of end cap 51 and seat body 52; The top that connects guide pillar 3 is plugged in the seat body 52 of bogie side frame guide pillar Connection Block 5; And stud with the abrasion cover in the seat body 52 of bogie side frame guide pillar Connection Block 5 and be connected guide pillar 3 cooperations, avoid bogie side frame guide pillar Connection Block 5 and be connected guide pillar 3 transition abrasion.Also evenly be provided with 3 and bogie side frame bonded assembly bolt hole on the end cap 51 of bogie side frame guide pillar Connection Block 5.
