Abstract
The invention discloses a structure of a disc brake. In the structure, a relieving cylinder and a spring chamber are arranged at the two ends of a cylinder body respectively; a communicating through hole is formed between the release cylinder and the spring chamber; a braking cylinder is arranged on the end face of the cylinder body at the same end as the spring chamber, and is provided with a circular section; a piston is arranged in the release cylinder; a guide rod passes through middle holes of the spring chamber and the release cylinder; one end of the guide rod is fixedly connected with the piston; a fastening bolt passes through the piston and the guide rod in sequence, and is fixedly connected with a braking body; a spring seat is arranged in the spring chamber, and is provided with a butterfly-shaped spring; the butterfly-shaped spring is used for tightly compressing the braking body; an annular piston is arranged in the braking cylinder; and a friction sheet is fixed on the outer end face of the braking body. The structure of the disc brake in the invention has the advantages of simplicity and working reliability.
Description
Technical field
The present invention relates to a kind of structure technology of plate disc brake, specifically is a kind of structure of plate disc brake.
Background technology
Disc type brake is widely used in mine hoist, the brake snub of large-scale traction winch and handling machinery, parking; And the emergency braking under the safety case, at present, at the plate disc brake of the use in above-mentioned field; Structurally not only there are more complicated, the higher defective of fault rate, simultaneously, owing to the reason above the structure; The braking force of transforming the drg of type is to be provided by retarding spring fully; Drg is by cylinder pushes piston, compression brake spring in the process of alleviating that declutches, the purpose of the alleviation of declutching of realization drg; Because retarding spring is using through long, occurs tired, damage easily; So, reduce easily the effect of braking, even brake failure can occur, cause the generation of safety misadventure.
Summary of the invention
The objective of the invention is to: to the existing defective of above-mentioned plate disc brake, propose a kind of structure of new-type drg, overcome existing drg because in structure aspects, existing above-mentioned defective.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: the structure of this a kind of plate disc brake comprises cylinder body, annular piston, braking body, Friction disk, pilot bar, piston, binding bolt, spring perch, belleville spring, alleviation cylinder, brake cylinder, spring housing, and this invents the two ends that said alleviation cylinder and spring housing are separately positioned on cylinder body, alleviates cylinder and between spring housing, is provided with the through hole that communicates; Brake cylinder is arranged on the cylinder body end face with the same end of spring housing; Brake cylinder is a ring cross-section, and piston is installed in to be alleviated in the cylinder, and guide rod passes from the interstitial hole of spring housing and alleviation cylinder; One end and the piston of guide rod are fixed together; Binding bolt passes piston and guide rod successively, closely is fixed together with brake body, in spring housing, is provided with spring perch; Spring perch is provided with belleville spring; Belleville spring tight compression braking body is equipped with annular piston in brake cylinder, be fixed with friction lining at the outer face of brake body.
Principle of work of the present invention is: in work be, cylinder part and equipment install and fix together, in alleviating cylinder, do not feed pressurized air or pressure oil; And when feeding in the brake cylinder, then annular piston carries out roof pressure with belleville spring to brake body, forms braking mode; And do not feed in the brake cylinder when feeding pressure oil in pressure oil, the alleviation cylinder; Then piston forms compressive state to retarding spring, and brake body leaves brake disc, release of brake.
Beneficial effect of the present invention: can know by principle of work of the present invention, since the mode that adopts belleville spring and brake cylinder to brake simultaneously, wherein any failure mechanisms; Can guarantee to brake effectively, so, adopt the piston structure of annular in addition; Because the piston of annular is applied to application force the border of brake body uniformly; Can guarantee that braking force is even, so that the present invention has is simple in structure, the advantage of reliable operation.
