Description of drawings
Fig. 1 is structural representation of the present invention.
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 represent most preferred embodiment of the present invention, further describes detailed technology content of the present invention and embodiment below in conjunction with accompanying drawing.But should note: mark shown in the drawings and embodiment should not regard the restriction to the technology of the present invention as, and any modification on basis of the present invention and increase all are considered as the scope of protection of the invention.
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 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 for realizing the position answer of brake facing assembly, provides the structural shape of two kinds of stage clips among the present invention, referring to Fig. 2,3.Stage clip 9 is a kind of response agencies of brake facing assembly, the certain different structure of its capable of choosing multiple, and the present invention 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.
Adjustable bolt 5 by slipper 10 bottoms carries out the adjusting of brake facing component height position, wherein, adjustable bolt 5 is threaded connection with armature 8, and the end cap section of adjustable bolt 5 stretches into the adjustment hole of slipper 10, the other end can stretch into the through hole of electromagnet 1, to realize adjusting.The brake facing assembly of drg by adjustable bolt 5 carry out the height adjusting, and by spindle guide to moving back and forth.
There is loosening risk in the adjustable bolt 5 of brake facing assembly, has therefore increased anti-looseness mechanism in the design, to guarantee the reliability of regulating mechanism.The anti-loosening scheme of adjustable bolt 5 of the present invention 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 among the present invention, other also belongs to the scope of this patent protection about the anti-loosening method of adjusting bolt herein.
Adjustable bolt 5 has certain free-running fit with slipper 10 adjustment holes of brake facing assembly, and the rotatable certain angle of brake facing assembly is used for cooperating of self-regulation and brake wheel.
After drg and the towing machine assembling, reach the purpose of regulating brake air gap by the height of regulating the brake facing assembly.
Fully contact with brake wheel during for 11 braking of assurance brake facing, braking is adopted spring with elastic element 4(the present embodiment) be loaded in the through hole of electromagnet 1, upper-lower position all is equipped with orientation assemble spare 2,3 in the through hole of electromagnet 1, the two ends of spring 4 peak at respectively orientation assemble spare 2,3, and the outer face of orientation assemble spare 3 contacts in armature 8.
Braking element 4 is when installing with electromagnet 1, at upper-lower position detent mechanism (also can select one to install at upper-lower position) is installed, 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 present invention has changed the structure that traditional braking device brake facing assembly and armature are fastenedly connected, brake facing assembly and armature separation design and rotatable certain angle.
Drg outage band-type brake, orientation assemble spare 3 is under the application force of spring 4, and armature 8 is pressed on the outwards motion through hole of electromagnet (but do not break away from) and top, and then makes the motion of brake facing assembly, until brake facing 11 contacts and locking with brake wheel, to realize the braking to 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.
Above the preferred embodiments of the present invention and principle are had been described in detail, for those of ordinary skill in the art, according to thought provided by the invention, will change in the specific embodiment, and these changes also should be considered as protection scope of the present invention.
