Described upper guide post is out the conical structure of centre hole, and it embeds described going up in the internal layer rubber coating, and its bottom is provided with and following guide pillar bonded assembly positioning boss, and the top is provided with and connects double-screw bolt installation groove;
Described guide pillar down is out the conical structure of centre hole, and it embeds in the described internal layer rubber coating down, and its top is provided with and upper guide post bonded assembly detent, and the bottom is provided with and connects double-screw bolt installation groove;
The described bottom of overcoat down is provided with the flange that has seam with the axle box bonded assembly, cover body inboard is up big and down small taper, so that be connected with following outer layer rubber, the cover body is embedded in described outer layer rubber cover and following internal layer rubber coating down, is provided for inside and outside layer rubber bonded assembly conical baffle between following outer layer rubber cover and the following internal layer rubber coating;
Described connection double-screw bolt is arranged in the centre hole of described upper guide post and following guide pillar, and both are connected.
It is two through holes of 180 ° that the unvulcanised upper surface of described internal layer rubber coating is opened phase difference along taper direction.
The utility model axle box suspension gear is installed in the both sides of the axle box suspension of rolling stock framework type bogie truck, under traction working condition, will pass on the axle box from the horizontal and vertical power of framework; Under damped condition, braking force is passed on the framework.
The beneficial effects of the utility model are:
1. simplified the axle box suspended structure greatly;
2. owing to adopt rubber, therefore can be by adjusting the layout tapering of rubber, satisfy the vertical performance requriements of vehicle, can open phase difference along taper direction at the unvulcanised upper surface of internal layer rubber is two through holes of 180 °, to satisfy the rigidity requirement of lateral direction of car, longitudinal register, guarantee the dynamic performance requirement of vehicle;
3. owing to adopt the rubber location, thereby reduced the abrasion of critical component, and easy access.
Description of drawings
Fig. 1 is the utility model schematic appearance;
Fig. 2 is a cut-away view of the present utility model.
The specific embodiment
Be described further below in conjunction with accompanying drawing.
The utility model axle box suspension gear is installed in the both sides of the axle box suspension of rolling stock framework type bogie truck.
As depicted in figs. 1 and 2, this axle box suspension gear comprise overcoat 1, go up outer layer rubber cover 2, go up internal layer rubber coating 4, upper guide post 5, down guide pillar 6, down outer layer rubber cover 8, down internal layer rubber coating 7, down overcoat 9, connect double-screw bolt 12.Wherein:
The top of last overcoat 1 is provided with the flange that has seam with the truck side sill bonded assembly, cover body inboard is up-small and down-big taper, so that be connected with last outer layer rubber 2, the cover body of last overcoat 1 is embedded in outer layer rubber cover 2 and last internal layer rubber coating 4, is provided for inside and outside layer rubber bonded assembly conical baffle 3 between last outer layer rubber cover 2 and the last internal layer rubber coating 4;
Following guide pillar 6 is for opening the conical structure of centre hole, and in the internal layer rubber coating 7, its top was provided with and upper guide post 5 bonded assembly detents under it embedded, and the bottom is provided with the installation groove that connects double-screw bolt 12;
The bottom of following overcoat 9 is provided with the flange that has seam with the axle box bonded assembly, cover body inboard is up big and down small taper, so that be connected with following outer layer rubber 7, following overcoat 9 cover bodies are embedded in down outer layer rubber cover 8 and following internal layer rubber coating 7, are provided for inside and outside layer rubber bonded assembly conical baffle 3 between following outer layer rubber cover 8 and the following internal layer rubber coating 7;
