About embodiment:
Refer to Fig. 1, Fig. 1 is the structural representation of the utility model drum brake one embodiment.The drum brake of the present embodiment comprises brake drum 1, first brake shoe 21, second brake shoe 22, wheel cylinder 3 and friction plate 4, the two ends of described wheel cylinder 3 are touched with the first end of described first brake shoe 21 and the second brake shoe 22 respectively and are connected, second end of described first brake shoe 21 and the second brake shoe 22 is individually fixed in described brake drum 1, described first brake shoe 21 and the second brake shoe 22 are hollow brake shoe, in described first brake shoe 21 and the second brake shoe 22, be respectively equipped with cooling liquid, described friction plate 4 is located at the inner peripheral surface of described brake drum 1, with described first brake shoe 21 and the circumferential frictional fit of the second brake shoe 22, the drum brake of the present embodiment also comprises the first cooling pipe 51, second cooling pipe 52, outlet conduit 53, intake pipe 54 and radiator 55, the two ends of described first cooling pipe 51 are communicated with the first end of the first brake shoe 21 with the second brake shoe 22 respectively, the two ends of described second cooling pipe 52 are communicated with second end of the first brake shoe 21 with the second brake shoe 22 respectively, one end of described outlet conduit 53 is communicated with described first cooling pipe 51, the other end is communicated with the water intake of described radiator 55, one end of described intake pipe 54 is communicated with described second cooling pipe 52, the other end of described intake pipe 54 is communicated with the water outlet of described radiator 55.Particularly:
Described friction plate 4 is fixedly installed at the inner peripheral surface of described brake drum 1.Described friction plate 4 is circular in one, and its outer circumferential face and the inner peripheral surface of described brake drum 1 match.In this programme, described friction plate 4 is directly fixed on the inner peripheral surface of described brake drum 1, the benefit of setting like this is: when brake drum 1 rotates, friction plate 4 is also along with described brake drum 1 rotates, when needs are braked, wheel cylinder 3 makes the first end of the first brake shoe 21 and the second brake shoe 22 expand outwardly respectively, so, on the one hand, namely the first brake shoe 21 and the second brake shoe 22 is made directly to rub with described friction plate circumference, and in friction process, the hot gas that first brake shoe 21 and the second brake shoe 22 produce, cooled gradually by the cooling liquid be located in the first brake shoe 21 and the second brake shoe 22, cooling liquid in first brake shoe 21 and the second brake shoe 22 then flows in radiator 55 dispels the heat, flow back again in the first brake shoe 21 and the second brake shoe 22 through described radiator 55 hand that dispels the heat, so, form the radiation system of a circulation, on the other hand, because friction plate 4 adopts composite material to be made, its material makes the heat conduction of itself comparatively slow, can not be passed through many hot gas to brake drum 1, therefore not need to dispel the heat to brake drum 1.
In this programme, by existing to brake drum 1 carry out heat radiation improve after, directly produce heat by the first brake shoe 21 and second brake 22, and the first brake shoe 21 and second brake 22 are directly cooled by cooling liquid, can avoid like this and adopt external equipment directly to spray water and cool, make drum brake to produce corrosion, add its working life.
In the present embodiment, described drum brake also comprises the water pump 56 be installed on described intake pipe 54.The benefit increasing described water pump 56 is, liquid circulation speed is accelerated, adds its cooling effectiveness.
In the present embodiment, described first brake shoe 21 and the second brake shoe 22 are installed in brake drum 1 by a mounting disc, and particularly, the external diameter of described mounting disc is slightly less than the internal diameter of brake drum 1.Second end of described first brake shoe 21 and the second brake shoe 22 is fixed on respectively by a fixing pin on the surface of described mounting disc, and described first brake shoe 21 and the second brake shoe 22 rotate relative to described mounting disc, so, when the first end that the two ends of wheel cylinder 3 promote the first brake shoe 21 and the second brake shoe 22 is expanded in the opposite direction, second end of the first brake shoe 21 and the second brake shoe 22 is then suitable to rotate to an angle in the opposite direction, and then makes the first brake shoe 21 and the second brake shoe 22 and friction plate 4 produce frictional force.Understandable, in other examples, the first brake shoe 21 and the second brake shoe 22 can not also be fixed by mounting disc, a wheel cylinder can be adopted equally to coordinate, be just no longer described in detail herein between their the second end.
Described wheel cylinder 3 comprises an oil hydraulic cylinder 31 and is located at first piston 32 and second piston 33 at described oil hydraulic cylinder 31 two ends, described first piston 32 and the second piston 33 contact with the first end of the first brake shoe 21 and the second brake shoe 22 respectively, when first piston 32 and the second piston 33 are pushed open to two ends, then promote the first brake shoe 21 and the second brake shoe 22 expands outwardly.
In the present embodiment, described drum brake also comprises a flange plate 6, and described flange plate 6 is located in described brake drum 1, and described break is connected with tire by flange plate 6.
In the present embodiment, describedly also comprise temperature transducer 7 and a controller 8, described temperature transducer 7 is installed on described first brake shoe 21 or the second brake shoe 22, and is connected with described controller 8; Described controller 8 is connected with described water pump 56.When temperature is too high, controller 8 controls water pump 56 and starts working.The benefit of such design is, if temperature is not high, then do not need to open water pump 56, and then do not need to accelerate the speed of circulation of cooling liquid and the amount of flow of cooling liquid, when temperature is too high time, then open water pump 56 to increase circular flow momentum and the speed of cooling liquid, and when amount of flow is less, the operating rate of water pump 56 then can reduce, so, make water pump 56 not need high efficiency work, increase the operating life of water pump 56.
Fan (scheming not shown) is provided with, for lowering the temperature to cooling liquid in described radiator 55.The radiator 55 of the present embodiment can be identical or similar with radiator 55 structure of motor, and just the structure of this radiator 55 is less.The fan of radiator 55 can share with engine radiator fan.
The utility model embodiment, on the one hand, by friction plate 4 being directly fixed on the inner peripheral surface of brake drum 1, making friction plate 4 directly produce with the first brake shoe 21 and the second brake shoe 22 and rubbing; On the other hand, first brake shoe 21 and the second brake shoe 22 are designed to hollow-core construction, cooling liquid is installed in the first brake shoe 21 and the second brake shoe 22, again by the first cooling pipe 51, second cooling pipe 52, outlet conduit 53 and intake pipe 54, to form a cooling recirculation system, thus cooling process is carried out to the first brake shoe 21 and the second brake shoe 22.Adopt in this way, avoid traditional mode and the problem of the break corrosion caused, extend the working life of drum brake, saved maintenance cost, also reduce the incidence rate of security incident.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
