Abstract
The utility model provides an axle box suspension and positioning device for a ball joint, which comprises a guide pillar, a wear-resisting sleeve, a ball joint and a joint positioning sleeve. The upper part of the guide pillar is provided with a flange with a spigot, the middle part is a ladder-like cylindrical axle body and the lower part is a cylindrical body. The top of the wear-resisting sleeve is provided with a positioning table connected with the ball joint. The cylindrical body of the wear-resisting body is cylindrical, the inner side is matched with the lower part of the guide pillar and the outer side is matched with the ball joint. The ball joint consists of an inner sleeve, an outer sleeve and a rubber sleeve positioned between the inner sleeve and the outer sleeve, and the inner sleeve is sleeved with the outer side of the cylindrical body of the wear-resisting sleeve. The top of the joint positioning sleeve is provided with the positioning table which is connected with the axle box, and the cylindrical box is cylindrical and the inner side of the cylindrical body is interference matched with the outer sleeve of the ball joint. The axle box suspension and positioning device has the advantages that: as the positioning device does not longitudinally restrain the up and down of a steering frame while horizontally and vertically providing the positioning stiffness of the steering frame through the ball joint, a reliable positioning device for the axle box of the frame type steering frame is provided.
Description
Technical field
The utility model relates to a kind of railway goods train bogie that is used for and adopts axle box to hang the ball and socket guide-pillar positioning device of location.
Background technology
Along with the raising of rolling stock running velocity, the framework type bogie structure that lorry need adopt axle box to hang, but still do not have the ball and socket axle box guide-pillar positioning device that is exclusively used in lorry at present.
The utility model content
In view of above-mentioned, the purpose of this utility model provides a kind of ball and socket axle box guide-pillar positioning device that is exclusively used in lorry.
For this reason, the utility model is by the following technical solutions:
A kind of ball and socket hanging and locating device of axle box comprises guide pillar, wear-resistant sleeve, ball and socket, joint locating bush, wherein:
The top of described guide pillar is provided with the flange that has seam with the truck side sill bonded assembly, and the guide pillar middle part is a ladder cylindricality axle body, and the guide pillar bottom is a cylinder;
The top of described wear-resistant sleeve is provided with and ball and socket bonded assembly positioning table, and the stack shell of wear-resistant sleeve is cylindrical, and free-running fit is adopted in its inboard bottom with described guide pillar, and free-running fit is adopted with described ball and socket in its outside;
Described ball and socket by interior cover, overcoat and in being folded in the rubber coating between cover and the overcoat forms, be placed in it outside stack shell of described wear-resistant sleeve;
The top of described joint locating bush is provided with and axle box bonded assembly positioning table, and its stack shell is cylindrical, and the inboard overcoat with described ball and socket of stack shell is an interference fit.
The outside face of described rubber coating is radially opened the groove of certain depth.
The material of described wear-resistant sleeve is a manganese steel.
The utility model 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 by this device; Under damped condition, braking force is passed on the framework by this device.
The beneficial effects of the utility model are:
1. because the vertical sink-float that does not retrain bogie truck of this registration device, and laterally, vertically provide the locating stiffness of bogie truck by ball and socket, therefore the axle box location for the framework type bogie truck provides a kind of failure-free registration device;
2. owing to adopt the manganese steel wear-resistant sleeve, thus the abrasion of critical component reduced, and easy access.
Description of drawings
Fig. 1 is the assembly figure of the utility model registration device;
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 is a kind of ball and socket hanging and locating device of axle box, is installed in the both sides of the axle box suspension of rolling stock framework type bogie truck.
As shown in Figure 1 and Figure 2, this ball and socket hanging and locating device of axle box mainly is made up of guide pillar 1, wear-resistant sleeve 2, ball and socket 3, joint locating bush 4.Wherein:

The material of wear-resistant sleeve 2 is selected Qsn6.5-10 for use, its top is provided with and ball and socket 3 bonded assembly positioning tables, and the stack shell of wear-resistant sleeve is cylindrical, and free-running fit is adopted in its inboard bottom with guide pillar 1, free-running fit is also adopted with ball and socket 3 in its outside, so that the maintenance of abrasion back;
Ball and socket 3 by interior cover, overcoat and in being folded in the rubber coating between cover and the overcoat forms, be placed in it outside stack shell of wear-resistant sleeve 2;
The top of joint locating bush 4 is provided with and axle box bonded assembly positioning table, and its stack shell is cylindrical, and the inboard overcoat with ball and socket 3 of stack shell is an interference fit, and the stack shell outside is a transition fit with the axle box force transmission hole.
In addition, rubber coating for realize laterally, the coupling of longitudinal rigidity, radially open the groove of certain depth at its outside face.
The utility model ball and socket axle-box positioning device is mainly used in the horizontal and vertical location of axle box suspension gear, and, longitudinal rigidity horizontal by rational Match are realized the vehicle operating requirement.For example: the thickness by optimizing rubber coating and radially open the groove of certain depth at the outside face of rubber coating, to satisfy horizontal and vertical locating stiffness requirement, guarantee the dynamic performance requirement of vehicle.
Under traction working condition, will pass on the axle box from the horizontal and vertical power of framework by this device; Under damped condition, braking force is passed on the framework by this device.
