Embodiment
In conjunction with Fig. 1 and Fig. 2, the braking body of present embodiment is set to cylindrical body, and the cylindrical body both sides are milled with symmetry plane 206; Cylindrical body inside arranges step hole, and the step hole center line departs from certain distance and parallel with the cylindrical body center line; Be provided with keyway 205 in the step hole, hole, the big footpath of step hole 202 is set to tapped hole 203 near the break end of body; Cylindrical body goes out groove 204 near step hole path hole 201 1 end mills, and groove is vertical with two side planes.
In conjunction with Fig. 3,201 places, path hole of braking body arrange the fixed cylinder liner plate 1 of band brake shoe, and 202 places, hole, the big footpath of step hole arrange the shell liner alive 3 of band brake shoe, and band brake shoe shell liner 3 alive axially moves by the feather key that is arranged in the dowel hole; Shell liner alive 3 center fixation of band brake shoe have the axis of guide 4, are with cover 5 in the dish spring on the axis of guide 4 external diameters, are with one group of butterfly spring group 6 on cover 5 cylindricals in the dish spring.The axis of guide 4 endoporus and attachment bolt 7 junctions screw the drive hold-down mechanism by fine thread and compress butterfly spring group 6, hold-down mechanism comprises the piston 10 that is arranged on the attachment bolt 7, the band dish spring abutment oil cylinder 8 that is connected with piston 10 Sealings, and band dish spring abutment oil cylinder 8 bases are connected with butterfly spring group 6; Form airtight oil pocket between piston 10 and the band dish spring abutment oil cylinder 8.By being screwed into attachment bolt 7, promoting piston 10, be with dish spring abutment oil cylinder 8 to move, thereby butterfly spring group 6 can be compressed.Be with on band dish spring abutment oil cylinder 8 cylindricals and adjust nut 9, the tapped hole 203 of adjusting nut 9 and braking body forms screw pair band dish spring abutment oil cylinder 8 is carried out axial limiting.Also be provided with oil cylinder cover plate 11 on the band dish spring abutment oil cylinder 8, connect dust cover 12 on the oil cylinder cover plate 11.
When brake disc is used, be arranged on the dish row brake support frame 14, adjust nut 9 and can in the tapped hole 203 of braking body 2, axially move by fine thread, when being screwed into adjustment nut 9, promote band dish spring abutment oil cylinder 8 compression butterfly spring groups 6 to the service braking position.Airtight oil pocket is connected by oil circuit and external hydraulic station, after the hydraulic station pressure oil output, overcome the compressive force of butterfly spring group 6, promoting piston 10 moves right, because the shell liner alive 3 of attachment bolt 7, the axis of guide 4 and band brake shoe forms the body that is rigidly connected, driving attachment bolt 7 when piston 10 moves right moves right, thereby the shell liner alive 3 that drives the band brake shoe moves right, further compress butterfly spring group 6, at this moment brake shoe just breaks away from brake disc 13, and lift just can rotate under the state of declutching.When lift is braked, shed oil pressure, compression butterfly spring group 6 is not having under the external force constraint, rely on self characteristics to do turgor movement, the shell liner alive 3 that promotes the band brake shoe is close to the elevation scheme Moving plate, drive braking body 2 and move right under the influence of reaction force, the fixed cylinder liner plate 1 that drives the band brake shoe is close to brake disc, thereby the elevation scheme Moving plate is realized service braking and emergency braking under the effect of both sides Block brake power.
Should illustrate that those skilled in the art within the spirit that does not break away from the invention and principle, any modification of doing, are equal to replacement, improvement etc. on the basis of above preferred embodiment, all should be included within the protection domain of the invention.
