Abstract
The invention relates to a foundation braking deviation prevention structure of a railway wagon. The structure comprises a brake beam, brake shoe holders, brake shoes and sliding block wear sleeves. The structure is characterized in that stop dogs are arranged at the roots of sliding blocks of the brake shoe holders. The structure has the advantages that the structure is simple, assembly is convenient, the use is safe and reliable, eccentric wearing of the brake shoes and rims of wheels is avoided, overhauling and maintenance are convenient, the structure is suitable for obliquely pulling lever braking or obliquely pulling unit braking, the structure is also suitable for being installed for vertical foundation braking, exchange can be realized, and the operating performance is not influenced.
Description
Technical field
The present invention relates to the anti-offset structure of a kind of railway truck foundation brake, belong to railway wagon brake technical field.
Background technology
On railway truck, transmit and amplify brake power and the part producing braking force is called foundation brake rigging, primarily of 5 kinds of parts compositions such as lever, pull bar, hem shoe gap automatic regulator, brake beam and brake shoe, it is the important component part of brake system of rail vehicle.
Truck brake rigging device can be divided into " single brake shoe braking " and " bilateral Block brake " according to the configuration of brake shoe both at home and abroad at present, can be divided into " fallaway type " and " modular " according to the version of transmission device; Draw the difference of the relative bolster position of (pressure) bar according to truck brake rigging device, middle pull bar Block brake and lower link Block brake can be divided into again; Different according to lever and longitudinal direction of car vertical guide angle, can be divided into again vertical type lever to brake and tilting lever is braked.
For the braking of vertical type lever, vehicle is in operational process, and in foundation brake rigging, the part such as lever and brake beam swings with the snakelike operation of vehicle, and substantially there is not lateral excursion problem, the abrasion caused wheel track are substantially suitable.But tilting lever is braked, no matter fallaway type, modular, or the bogie truck of the middle type such as pull bar, lower link, all leaves a certain amount of safety distance for ensureing by circuits such as different radii curve and station place where Taoist rites are performed, track switches between its foundation brake rigging brake beam end and side frame chute.Shown by utilization and a large amount of investigational data: when lorry runs through the varied sections such as curve, track switch, foundation brake rigging brake beam all has the skew action of side and trend, and then brake beam side brake shoe and wheel rim recline, and cause brake shoe partial wear, wheel rim eccentric wear, increases maintenance cost.
Summary of the invention
The object of the invention is to there is skew for foundation brake rigging in existing railway truck operation, cause wheel rim abrasion and brake shoe abrasion to aggravate phenomenon, the anti-offset structure of railway truck foundation brake providing a kind of structure simple, convenient for installation and maintenance.
In order to realize this purpose, the invention provides the anti-offset structure of a kind of railway truck foundation brake, comprising brake beam, brake head, brake shoe, slide block abrasion cover, it is characterized in that: brake head slide block root is provided with a block.
Advantage of the present invention is: structure is simple, be convenient to assembling, application safety is reliable, avoid brake shoe and wheel rim eccentric wear, facilitate repair and maintenance, be suitable for the braking of cable-stayed type lever or cable-stayed type brake unit, also be applicable to installing to vertical type foundation brake equally, can exchange, drive ability is not affected.

Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the birds-eye view of brake head.
Detailed description of the invention
As shown in Figure 1, the anti-offset structure of railway truck foundation brake of the present invention comprises: brake beam 1, brake head 2, brake shoe 3, slide block abrasion cover 4.Brake head 2 is set in the end of brake beam 1, and by rivet or bolt 8 affixed, the slide block 5 that slide block abrasion cover 4 is set in brake head 2 is outside, by rivet 7 rivet clasp.
As shown in Figure 2, Figure 3, Figure 4, the brake head 2 of the anti-offset structure of railway truck foundation brake of the present invention, mainly add block 6 at its slide block 5 root, realize the anti-offset phenomenon of foundation brake rigging in vehicle operating, block can realize by welding or directly casting out.
The anti-offset structure of railway truck foundation brake of the present invention is assembled in hand of truck bogie side frame chute, and the slide block that the slide block 5 of railway truck foundation brake anti-deviation device brake head 2 is set with wears away cover 4 end and side frame chute root, and leaves certain safety distance.Be in operation, the anti-offset structure of railway truck foundation brake swings with vehicle operating.
When vehicle operating curve or section with a switch or switches, the trend of the oriented offset inboard of foundation brake rigging, but in migration process, limit by brake head slide block root block, foundation brake rigging cannot offset, now, for to ensure that leaving a certain amount of safety distance by circuits such as different radii curve and station place where Taoist rites are performed, track switches still exists between foundation brake rigging brake beam end and side frame chute, can not have any impact to operation, but fundamentally ensure that foundation brake rigging can not offset, avoid eccentric wear and the abrasion aggravation phenomenon of this side brake shoe and wheel rim.
