Description
Technical field
It is more more particularly to one kind the utility model relates to the brake beam and brake apparatus in a kind of railway goods train bogie
Roller composite brake beam and brake apparatus.
Background technique
Composite brake beam is the critical component in railway goods train bogie, main function be when the vehicle is braked,
Under the thrust of brake lever, composite brake beam is moved along side frame sliding slot to wheel, so that brake shoe is close to wheel tread,
To play braking action；When release of brake, glides by composite brake beam self weight along the sliding slot being located on side frame, make to make
It is dynamic to alleviate.To guarantee that composite brake beam can be successfully moved forward and backward in side frame sliding slot, China successively uses roller and cunning
The fit system of two kinds of forms of block.Using the composite brake beam of roller form, mobile frictional force is small, and alleviation performance is good, still
It is easy that brake beam is made to generate " bowing " phenomenon, i.e., under the effect of gravity, brake beam is using roller axle as axle center, the arch portion of brake beam
It is point sagging, so that brake shoe upper end is contacted with wheel tread greater than lower end, to generate brake shoe partial wear.
To solve the problems, such as brake shoe partial wear, roller form is just changed to the form of diamond shape or square slider, it is inclined to reduce brake shoe
Mill uses the form of square slider at present, further avoids brake beam and " bows " generation of phenomenon.For example,
CN201116128Y discloses a kind of channel steel brake beam assembling device comprising a station, a support frame, several blocks, two
Chute hole, a side block blocks, two sliding blocks, two levers, four fixed plates, a drive rod, a cylinder, a connecting pipeline, a switch and one
Cylinder saddle.When using arrangement above assembling grove steel brake beam, it is only necessary to be placed into arch steel channel beam, steel channel beam and pillar specified
Position, moving switch can assemble channel steel brake beam in place, can remove after spot welding is secured.But since sliding block is in sliding slot
Interior generation sliding friction, frictional resistance is larger, reduces transmission efficiency, and it is undesirable to alleviate performance.
