Description
Technical field
The utility model belongs to wind-driven generator device technical field, specifically relates to a kind of Novel brake structure.
Background technique
Along with the development of science and technology, the social demand to the energy is in continuous increase, and mankind's environmental consciousness is in enhancing, more and more higher to the requirement of air quality, international, the domestic proportion of utilization to novel energies such as various pollution-free clean energy resource, renewable energy sourcess improves constantly.Wind energy is use more for convenience in all novel energies, and a kind of energy that user cost is lower can play considerable effect in international energy.
At present, a lot of brake plunger end face is plane structure, because processing exists certain difference, partial brake device piston end surface and oil hydraulic cylinder bottom surface are fitted very well, cause hydraulic oil can not enter the faying surface of piston end surface and oil hydraulic cylinder bottom surface, when making piston initialization, (piston not operating before) hydraulic oil active area to piston is too small, as Fig. 1, shown in Fig. 2, traditional piston end surface is plane structure, in use, its hydraulic oil to the active area of piston as A, shown in B position, because active area is too small and cause the too high and piston delay of response of piston breakout pressure, affect the correlated performance of break.
Model utility content
For solving the problem, the utility model provides a kind of Novel brake structure.Thus when original operating state intensified pressure oil and the area of contact of piston end surface, to reduce the breakout pressure of piston.
The utility model is achieved by following technical solution.
A kind of Novel brake structure, the piston comprising break body and coordinate with the piston cavity of break body, described break body bottom portion or side are provided with filler opening, Sealing is provided with between described piston and break inner body wall, described piston base is provided with groove, and described groove and break body bottom portion form a circular cavity.
Described piston base is provided with boss, and boss and break body bottom portion form an annular housing.
The area of described groove is greater than the basal area of 1/2nd pistons.
The area of described boss is less than the basal area of 1/2nd pistons.
Described piston head is also provided with tapped hole.
The geometrical center of described groove is positioned on the axis of piston.
The geometrical center of described boss is positioned on the axis of piston.
The beneficial effects of the utility model are:
Compared with prior art, the utility model, by arranging groove or boss in piston base, makes the surface of contact of piston end surface and piston cavity bottom surface reduce, thus to increase before piston starts operation hydraulic oil to piston end surface active area, to reduce the breakout pressure of piston.The utility model structure is simple, is convenient to manufacture, and has good economic benefit and social benefit, can in wind-driven generator device technical field wide popularization and application.

In figure: 1-break body, 2-piston, 3-Sealing, 4-circular cavity, 5-annular housing, 11-filler opening, 12-piston cavity, 21-tapped hole, 22-groove, 21-boss.
Embodiment
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 3, a kind of Novel brake structure described in the utility model, the piston 2 comprising break body 1 and coordinate with the piston cavity 12 of break body 1, bottom described break body 1 or side is provided with filler opening 11, Sealing 3 is provided with between described piston 2 and break body 1 inwall, be provided with groove 22 bottom described piston 2, bottom described groove 22 and break body 1, form a circular cavity 4.The technical program by arranging groove 22 bottom piston 2, by forming a circular cavity 4 bottom groove 22 and break body 1, thus increase piston 2 before beginning action with the area of contact of pressure oil, to reduce the breakout pressure of piston and to improve the being quick on the draw property of piston.The technical program is applicable to break and enters oil condition from bottom.
As shown in Figure 4, a kind of Novel brake structure described in the utility model, the piston 2 comprising break body 1 and coordinate with the piston cavity 12 of break body 1, described break body 1 side is provided with filler opening 11, Sealing 3 is provided with between described piston 2 and break body 1 inwall, be provided with boss 23 bottom described piston 2, bottom described groove 23 and break body 1, form an annular housing 5.The technical program by arranging boss 23 bottom piston 2, by forming an annular housing 5 bottom groove 23 and break body 1, thus increase piston 2 before beginning action with the area of contact of pressure oil, to reduce the breakout pressure of piston and to improve the being quick on the draw property of piston.The technical program is applicable to break and enters oil condition from the side.
For guaranteeing the active area effectively increasing hydraulic oil, with the being quick on the draw property of the breakout pressure and piston that reduce piston.The area of described groove 22 is greater than the basal area of 1/2nd pistons 2; The area of described boss 23 is less than the basal area of 1/2nd pistons 2.
As shown in Figure 5, Figure 6, described piston 2 top is also provided with tapped hole 21.For connecting accessory.
For guaranteeing piston 2 stationarity in running, the geometrical center of described groove 22 is positioned on the axis of piston 2.The geometrical center of described boss 23 is positioned on the axis of piston 2.
The utility model effectively can increase the area of contact of pressure oil and piston before piston action, with the being quick on the draw property of the breakout pressure and piston that reduce piston.According to different brake structurals, adopt different piston structures, the area of contact of piston and pressure oil during to increase initialization; For the break of oil-feed bottom piston cavity, plunger designs becomes groove structure: for the break of oil-feed bottom piston cavity, plunger designs becomes boss structure.
