Abstract
The utility model relates to a dual-shoe drum brake, and belongs to the field of automobile manufacture. Two camshafts are connected with a brake bottom plate through bushings in a rotating way respectively. Brake shoe groups are connected with the brake bottom plate through pin shafts in a rotating way respectively. One end of each locking plate is fixedly connected with the corresponding brake shoe group through screws, and the other end of each locking plate is fixedly connected with the corresponding pin shaft. Two rollers are fixedly connected with each brake shoe group through two hook springs respectively. The two ends of each connecting spring are hooked with the corresponding brake shoe group. The rollers are connected with the camshafts in a rolling way. The brake provided by the utility model has the advantages that the dual-shoe drum brake is novel in structure; and the braking torque can be improved to over 75 percent under the condition of no changes in the size and the structure of a brake drum.
Description
Technical field
The utility model belongs to automobile manufacturing field, refers in particular to a kind of break.
Background technique
Current automotive industry growing along with the increase of truck deadweight tonnage, requires also in continuous increase, to increasing its braking moment braking moment.Present hub type brake is all that single shoes is realized braking effect.Can't be in the situation that not varying sized and structure realizes the increase of braking moment.
Summary of the invention
The utility model provides a kind of pair of shoes hub type brake, can't be in the situation that not varying sized and structure realizes the problem of the increase of braking moment to solve prior art.
The technological scheme that the utility model is taked is: camshaft one is rotationally connected by lining one and braking bottom board, brake shoe group one is rotationally connected by bearing pin one and braking bottom board, one end of locking plate one with screw one be fixedly connected with brake shoe group one, the other end is fixedly connected with bearing pin one, two rollers one hook spring one by two respectively and are fixedly connected with brake shoe group one, link spring one two ends and brake shoe group one hook joint, two rollers one roll with camshaft one and are connected; Camshaft two is rotationally connected by lining two and braking bottom board, brake shoe group two is rotationally connected by bearing pin two and braking bottom board, one end of locking plate two with screw two be fixedly connected with brake shoe group two, the other end is fixedly connected with bearing pin two, two rollers two hook spring two by two respectively and are fixedly connected with brake shoe group two, link spring two two ends and brake shoe group two hook joints, two rollers two roll with camshaft two and are connected.
The utility model has the advantage of: novel structure, realized braking moment being increased in the situation that do not change brake drum size and structure, braking moment can be brought up to more than 75%.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is explosive view of the present utility model;
Fig. 3 is the rear flank view of Fig. 1.
Embodiment
Camshaft 1 is rotationally connected by lining 1 and braking bottom board 1, brake shoe group 1 is rotationally connected by bearing pin 1 and braking bottom board 1, locking plate one 9 one ends with screw 1 be fixedly connected with brake shoe group one, the other end is fixedly connected with bearing pin one, two rollers 1 hook spring 1 by two respectively and are fixedly connected with brake shoe group one, link spring one 10 two ends and brake shoe group one hook joint, two rollers 1 roll with camshaft one and are connected; Camshaft 23 ' by lining 22 ' be rotationally connected with braking bottom board 1, brake shoe group 26 ' by bearing pin 27 ' be rotationally connected with braking bottom board 1, locking plate 29 ' one end is with screw 28 ' be fixedly connected with brake shoe group two, the other end is fixedly connected with bearing pin two, two rollers 25 ' hook spring 24 by two respectively ' be fixedly connected with brake shoe group two, link spring 2 10 ' two ends and brake shoe group two hook joints, two rollers 25 ' rolling with camshaft two is connected.
Two shoes all use a braking bottom board to fix, the two ends of braking bottom board drive respectively two brake shoe irons by two camshafts respectively and open, the braking purpose of realization to brake hub, owing to being that two brake shoe irons are braked simultaneously, just be equivalent to fill in a brake hub two breaks in work, thereby braking moment is increased, realized the effect that in the situation of not varying sized and structure, braking moment is increased.
