Therefore, develop a kind of novel steering frame unit brake device that is applicable to railway truck, to solve existing railway goods train bogie unit brake device because the series of problems that mounting means was brought of brake cylinder has very real, positive meaning.
The utility model content
Main purpose of the present utility model provides and a kind ofly can solve existing railway goods train bogie unit brake device because the gap because of larger between the attachment face that the mounting means of brake cylinder brings is caused the assembling parts difficulty, affect assembly precision and assembly reliability, use rear bolt easily to become flexible the railway goods train bogie unit brake device that affects the series of problems such as traffic safety for a long time.
To achieve these goals, the utility model specifically provides a kind of technic relization scheme of railway goods train bogie unit brake device, comprising: brake cylinder, brake beam form, back of the body push rod forms, front brake lever forms, rear brake rod forms, the compression lock is transferred device, brake shoe, brake shoe key, β latch, bolt, black nut, round pin and spring cotter; The two ends that described brake beam forms are installed in respectively in the chute of two bogie side frames of bogie truck, described brake cylinder uses bolt by the mounting hole that carries, nut is installed in described brake beam and forms, be provided with packing ring between two attachment faces of described brake beam composition and brake cylinder, eliminate that described brake beam forms and two attachment faces of brake cylinder between the gap, solve the assembling parts difficulty that exists the gap to cause between two attachment faces owing to described brake beam composition and brake cylinder, the problems such as bolt easily becomes flexible, improve the know clearly assembly precision of railway goods train bogie unit brake device and the reliability of assembling, safety and the service life of having improved greatly railway truck greatly.
As further improvement of the utility model, described packing ring is spherical washer, after bolted compresses, the certainly distortion that utilizes described spherical washer to produce, can effectively eliminate the impact that manufacturing errors that brake cylinder and brake beam form attachment face causes assembling, simultaneously, because described spherical washer, can effectively be cleared up the certainly easy loosening problem of bolt from the predetermincd tension that distortion brings.
As further improvement of the utility model, the mounting hole of described brake cylinder is provided with the counterbore of one section taper in a side that forms near brake beam, when described brake cylinder is installed, described taper counterbore contacts with the land portions of described spherical washer, be conducive to the smoothing between the several attachment points of described brake cylinder, be convenient to the location of described spherical washer, make simultaneously described spherical washer stressed more even, prolong the service life of described spherical washer.
The utility model first the brake beam of railway goods train bogie unit brake device form and the attachment face of brake cylinder between be provided with packing ring, solved existing railway goods train bogie unit brake device because the assembling parts difficulty is caused in the gap because of larger between the attachment face that the mounting means of brake cylinder brings, affect assembly precision and assembly reliability, bolt easily becomes flexible problems such as affecting traffic safety after long-term the use, improve the know clearly assembly precision of railway goods train bogie unit brake device and the reliability of assembling, safety and the service life of having improved greatly railway truck greatly.
