Abstract

The utility model relates to an initiative resetting device for a railway wagon bogie. The initiative resetting device is characterized by being arranged between a swing bolster of the railway wagon bogie and a braking beam of the railway wagon bogie. The initiative resetting device comprises an installing component connected to the swing bolster in a fastening mode, a clamp arranged at the end, opposite to the swing bolster, of the braking beam in a clamping mode, and an elastic component with one end fixedly connected with the installing component through a fastening piece in a fastening mode and the other end connected with the clamp in a fastening mode. The elastic component can store energy when a vehicle brakes and deforms, and releases the energy to enable the braking beam to reset initiatively when braking of the vehicle is released. Due to the fact that the elastic component is adopted to be connected with the swing bolster and the braking beam, and the recuperability of a foundation braking device can be provided, the situation that after the braking is released, a brake shoe is not separated from a vehicle wheel is effectively prevented.

Description

Positive return device for railway goods train bogie
Technical field
The utility model relates to a kind of foundation brake rigging for railway goods train bogie, particularly about a kind of positive return device for railway goods train bogie.
Background technology
The foundation brake rigging of Tiebar structure in the most employing of China railways roller bearing adapter stabilizer bar at present, it is that whole brake equipment exists differential seat angle and assembling to have drag etc. at lateral direction of car mass distribution inequality, brake equipment floating lever and truck dead lever that this device exists because alleviating not enough brake shoe and the indissociable defect of wheel, the reason that has this defect of causing after release of brake.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of simple in structure, reliable in function for the positive return device of railway goods train bogie.
For achieving the above object, the utility model is taked following technical scheme: a kind of positive return device for railway goods train bogie, it is characterized in that, and this positive return device is arranged between the bolster and brake beam of railway goods train bogie; Described positive return device comprises that one is fastenedly connected the installation component on described bolster, one is installed on the clamp of described brake beam and the relative one end of described bolster, and an one end is fastenedly connected by a fastener elastic component that described installation component, the other end are fastenedly connected described clamp; Described elastic component is deformation energy when car brakeing, releases energy and make described brake beam positive return when car brakeing is alleviated.
Described installation component comprises a mount pad, a bolt, a nut, an adjusting pad, a packing ring and a spring cotter; Described mount pad is inverted L-shaped, and its horizontal edge is fastenedly connected on described bolster by described screw bolt and nut level, the vertical unsettled side at described bolster of vertical edge; Described adjusting pad is arranged between the horizontal edge and bolster of described mount pad, between the head of described bolt and mount pad and described nut and bolster, described packing ring is all set, and described spring cotter is radially plugged in the bottom of bolt described in spiral shell for preventing described bolt falling.
Described clamp is gyroscope-like, and the coupling end of described clamp is vertically offered a square opening.
Described elastic component is the shell fragment that is rugosity, one end of described shell fragment is fastenedly connected the vertical edge outside at described mount pad by fastener, and the other end of described shell fragment prevents that through being fastenedly connected one by another fastener after described square opening described shell fragment from ejecting the link stopper of described square opening.
Described fastener is rivet.
The utility model is owing to taking above technical scheme, and it has the following advantages:
1, the utility model adopts shell fragment to connect bolster and brake beam, and the recuperability of foundation brake rigging can be provided, thereby effectively prevents brake shoe and the unseparated situation of wheel after release of brake.
2, the clamp coupling end that the utility model is installed on brake beam offers square hole, allows shell fragment in square hole, to have sway, thereby guarantees not affect the transverse shifting of bolster.
3, the utility model is plugged in one end employing tightening of rivet block of the shell fragment in clamp coupling end square hole, can prevent coming off of brake beam.
4, the adjusting pad arranging between mount pad of the present utility model and bolster can be adjusted the relative position of shell fragment and brake beam, strong adaptability.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model
The specific embodiment
Below in conjunction with drawings and Examples, to of the present utility model, be described in detail.
As shown in Figure 1, the utility model is, between the bolster 1 of railway goods train bogie and brake beam 2, positive return device 3 is set, and this positive return device 3 comprises a mount pad 30, a bolt 31, a nut 32, an adjusting pad 33, a packing ring 34, a spring cotter 35, a clamp 36, a shell fragment 37, a block 38 and some rivets 39.
Wherein, mount pad 30 is inverted L-shaped, and its horizontal edge is fastenedly connected on bolster 1 by bolt 31 and nut 32 levels, the vertical unsettled side at bolster 1 of vertical edge.Adjusting pad 33 is arranged between the horizontal edge and bolster 1 of mount pad 30, and a packing ring 34 is all set between the head of bolt 31 and mount pad 30 and nut 32 and bolster 1, and the bottom that spring cotter 35 is radially plugged in bolt 31 comes off for preventing bolt 31.Clamp 36 is gyroscope-like, and it is installed on one end that brake beam 2 is relative with bolster 1, and the coupling end of clamp 36 is vertically offered a square opening.Shell fragment 37 is rugosity, its one end is fastenedly connected the vertical edge outside at mount pad 30 by some rivets 39, the other end of shell fragment 37 is plugged in the square opening of clamp 36 coupling ends, and block 38 is fastenedly connected the bottom of shell fragment 37 and ejects the square opening of clamp 36 in order to prevent shell fragment 37 by rivet 39.
Illustrate use flow process of the present utility model below:
When railway wagon brake, brake lever (not shown) drives brake beam 2 to move forward, and causes brake shoe 4 to hold wheel tightly and realizes braking, and the clamp 36 that is simultaneously installed on brake beam 2 one end is also with spring plate 37 to make it deformation energy.When car brakeing is alleviated, brake beam 2 retreats under the effect of gravity and shell fragment 37, and brake shoe 4 is separated with wheel, reaches the object of positive return.
The various embodiments described above are only for illustrating the utility model; wherein the structure of each parts, connection mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
