Abstract
The utility model discloses a coil structure of a retarder, which comprises coils and outer insulating paper, wherein the outer insulating paper covers the external circumferential surface of the coils. The coil structure of the retarder is characterized in that the coil structure additionally comprises inner insulating paper, end surface insulating paper and a plurality of heat-shrinkable fastening bands, the inner insulating paper covers the internal surface of the coils, the end surface insulating paper covers the end surface of the coils, the heat-shrinkable fastening bands are annularly and tightly wound on the outer insulating paper, the end surface insulating paper and the inner insulating paper. By adopting the structure, the situations that the coils vibrate and are rubbed when a vehicle runs, the coils are heated and expanded when the retarder works, the temperature of the coils is reduced and the coils are shrunk when the retarder does not work and friction is caused because the turns of the coils get loose and are apt to be displaced relatively can be effectively avoided, and therefore the problem of short circuit or open circuit caused by damages of enameling films of the coils because of friction can be reduced.
Description
Technical field
The utility model relates to vehicle retarder field, particularly relates to a kind of loop construction of retarder.
Background technology
As to the introduction in the vehicle retarder principle, during retarder work, the coil inside energising of retarder forms magnetic field and produces current vortex then, carries out car brakeing.The coil of retarder is the core component of retarder.During retarder work, coil can generate heat and shake.
The structure of existing retarder as shown in Figure 3, Figure 4, coil 1 adopts plastic skeleton 2 to fix, and adds in coil 1 outside that then insulating paper 3 protects.There is following shortcoming in this structure:
A), plastic skeleton 2 do not have elasticity, when retarder was worked, coil 1 heating volumetric expansion can be big with plastic skeleton 2 supports, when retarder was not worked, plastic skeleton 2 can't return, causes coil 1 loosening.Easily produce relative displacement and friction occurs between the per share coil in the loosening back of coil 1, friction will make the enamel-cover film of the enamelled wire of coil 1 damage and cause short circuit or open circuit, and cause the retarder fault;
B), 2 pairs of coils of plastic skeleton do not have the pretension effect, in the vehicle operating process, the shake that coil 1 is not stopping, the pretightning force effect that neither one adds, be prone to friction between the coil 1 per share coil, friction will make the enamel-cover film of the enamelled wire of coil damage and cause short circuit or open circuit initiation retarder fault;
C), plastic skeleton 2 adopts plastic materials, this material be the non-conductor of heat, after retarder work heating, can not effectively heat be distributed, and easily causes coil 1 to be burnt, initiation retarder fault.
Therefore, be necessary to design a kind of loop construction of new retarder in order to solve coil heat radiation and vibration problems.
The utility model content
Technical problem to be solved in the utility model is the enamel-cover film that easily shakes the enamelled wire that the friction damage coil takes place at the loop construction of existing retarder, cause contact between the enamelled wire of coil and short circuit or open circuit and existing loop construction is difficult for heat radiation, coil easily produces high temperature and usually causes the problem of burning.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of loop construction of retarder, comprise coil, external insulation paper, external insulation paper covers on the outer circumference surface of coil, it is characterized in that, the loop construction of described retarder also comprises interior insulating paper, end face insulating paper, some pyrocondensation restraint zones, interior insulating paper covers on the inner surface of coil, and the end face insulating paper covers on the end face of coil, fastening being wrapped on external insulation paper, end face insulating paper, the interior insulating paper of described some pyrocondensation restraint zone ring-types.
Described some pyrocondensation restraint zones are circumferentially uniform along coil.
Beneficial effect
The loop construction of retarder described in the utility model supports and insulation protection coil by adopting interior insulating paper, external insulation paper, end face insulating paper, uses the pyrocondensation restraint zone will be fastening with upper-part then; This structure can solve that appeal exists in the prior art a) and b) shortcoming, and cover and support, improved the radiating efficiency of coil greatly, solved above-mentioned c at the insulating paper that the periphery of coil all adopts) defective.
In addition, except coil, the utility model only adopts insulating paper and two kinds of members of pyrocondensation restraint zone, lighter than available technology adopting plastics and two kinds of members of insulating paper, for the retarder of using 8 coils, a retarder is used always about the light 0.8kg of retarder than existing, reduces the weight of whole retarder product.

Fig. 2 is the end view of structure shown in Figure 1.
Fig. 3 is the cutaway view of the loop construction of existing retarder.
Fig. 4 is the left view of structure shown in Figure 3.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2; the loop construction of retarder described in the utility model; comprise coil 10, external insulation paper 20, interior insulating paper 30; end face insulating paper 40; three pyrocondensation restraint zones 50; coil 10 is by interior insulating paper 30 fixing and insulation, uses external insulation paper 2 and 40 insulation protections of end face insulating paper on the outer circumference surface of needs insulation and end face, will effectively connect with upper-part with three pyrocondensation restraint zones 50 then.Pyrocondensation restraint zone 50 is a kind of at the hot material that can tighten automatically down, when retarder was worked, coil 10 heating temps raise, and at this moment pyrocondensation restraint zone 50 tightens automatically, coil 10 is applied a pretightning force, guarantee that coil 10 can not form relative displacement and friction between per share; When retarder was not worked, temperature descended, and pyrocondensation belt unclamps automatically.
More than show and described basic principle, principal character and the advantage of the present utility model of utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
