Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a kind of structural representation of stage clip.
Fig. 3 is the structural representation of another kind of stage clip.
The specific embodiment
Accompanying drawing can be represented most preferred embodiment of the present utility model, further describes detailed technology content of the present utility model and embodiment below in conjunction with accompanying drawing.But should note: mark shown in the drawings and embodiment should not regard that to the utility model technology limitation any modification on the utility model basis and increase all are considered as the scope of the utility model protection as.
Referring to Fig. 1-3, the present embodiment magnet stopper comprises electromagnet 1, armature 8, slipper 10, brake facing 11, and drg electromagnet 1 is connected by center bolt 7 with armature 8, and center bolt 7 is an outer-hexagonal head half thread bolt.Be under the drg "on" position under the normality, electromagnet 1 and armature 8 adhesives; And when drg outage band-type brake, armature 8 breaks away from electromagnet 1 and moves to the brake wheel direction.
The another side of armature 8 connects two stage clips 9 by screw 14, and the elastic top splenium 9-1 of stage clip 9 contacts in the lateral surface of slipper 10, and slipper 10 is pressed to armature 8 one sides.Stage clip 9 is used to realize the position answer of brake facing assembly, provides the structural shape of two kinds of stage clips in the utility model, referring to Fig. 2,3.Stage clip 9 is a kind of response agencies of brake facing assembly, the different structure of its optional majority kind certainly, and the utility model exemplifies two kinds of structures, and other structure also belongs to the category of this stage clip protection.
The lateral surface of slipper 10 and brake facing 11 bondings form the brake facing assembly, and the lateral surface of brake facing 11 is processed into certain radian according to brake wheel.
There is loosening risk in the adjustable bolt 5 of brake facing assembly, has therefore increased anti-loosening mechanism in the design, to guarantee the reliability of regulating mechanism.The anti-loosening scheme of the utility model adjustable bolt 5 in the drg course of action, exemplify a kind of (difference on other anti-loosening just method): the side at armature 8 leaves countersunk threaded, adopt binding bolt 6 to carry out fastening, for avoiding destroying the screw thread of adjustable bolt 5, put the cushion block of a bronze medal base in the end that binding bolt 6 contacts adjustable bolt 5.Only exemplify a kind of anti-loosening scheme in the utility model, other also belongs to the scope of this patent protection about the anti-loosening method of regulating bolt herein.
After drg and the towing machine assembling, reach the purpose of regulating brake air gap by the height of regulating the brake facing assembly.
For guaranteeing that brake facing 11 glancing impacts fully contact with brake wheel, braking is adopted spring with elastic element 4(present embodiment) be loaded in the through hole of electromagnet 1, upper-lower position all is equipped with location assembly parts 2,3 in the through hole of electromagnet 1, the two ends of spring 4 peak at location assembly parts 2,3 respectively, and the outer face of location assembly parts 3 contacts in armature 8.
Braking element 4 is when installing with electromagnet 1, upper-lower position installing and locating mechanism (also can select one to install) at upper-lower position, to guarantee the restoring force of elastic element 4, can guarantee the stressed balance of brake facing assembly upper-lower position simultaneously, so that brake facing 11 fully contacts with brake wheel.
The utility model has changed the structure that traditional braking device brake facing assembly and armature are fastenedly connected, brake facing assembly and the also rotatable certain angle of armature separation type design.
Drg outage band-type brake, location assembly parts 3 under the application force of spring 4, the outwards motion through hole of electromagnet (but do not break away from) and roof pressure armature 8, and then make the motion of brake facing assembly, contact and locking with brake wheel until brake facing 11, to realize braking towing machine.When main frame turns round, the adhesive of energising rear brake is that armature 8 resets, and the brake facing assembly needs to break away from brake wheel, and the answer of brake facing assembly relies on the elastic-restoring force of stage clip 9, under the effect of stage clip restoring force, the initial position when the brake facing assembly returns back to the drg adjusting.
More than preferred embodiment of the present utility model and principle are had been described in detail; for those of ordinary skill in the art; according to the thought that the utility model provides, the part that on the specific embodiment, can change, and these changes also should be considered as protection domain of the present utility model.
