Abstract
The utility model relates to a piston-type energy-storage spring brake air chamber, which comprises a middle body, a cylinder body, an upper cover and a dust-proof device, wherein one end of the middle body is connected with the upper cover through a catch hoop, and the other end of the middle body is connected with the cylinder body through a bolt, a spring is arranged in the cylinder body, a piston is arranged on the spring, a Y-shaped seal ring is arranged between the piston and the cylinder body, and the dust-proof device is welded at the bottom of the cylinder body through a nut, the bottom of the cylinder body is provided with an air hole on the welding portion of the nut, a filler is arranged in a groove of the nut, and a sheath is arranged on the filler. The piston-type energy-storage spring brake air chamber has the advantages that since impurities such as sand, dust and the like in air are thoroughly filtered, thereby leading the cylinder body, the piston and the spring not to be failure in early stage because of corrosion, plucking and the like, and the Y-shaped seal ring can not be abraded in early stage because of the entering of impurities such as mud and the like, thereby prolonging the service span of the air chamber, and guaranteeing the running security.
Description
Technical field
The utility model relates to a kind of piston type energy storage spring brake chamber.
Background technology
Running car is on the more abominable road surface of environment, as uncompleted highway, sandstone road, road etc., or travel at the many environment of dust, as cement mill, ore deposit factory, building site etc., need glancing impact at automobile, outer circulation type is all adopted in the intake and exhaust in the stopping brake chamber of the piston type energy storage spring brake chamber on the market, and dust keeper is simple, inefficiency, impurity such as inspiration silt and dust cause the air chamber early failure easily.
The utility model content
The purpose of this utility model provides a kind of piston type energy storage spring brake chamber, causes air chamber early failure, ineffective deficiency to overcome existing former air chamber dust keeper because of the reason of silt and dust etc.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of piston type energy storage spring brake chamber, comprise middle body, cylinder body, loam cake and dust keeper, an end of body and loam cake are by anulated connection in described, and the other end of middle body is connected with cylinder body by bolt, is provided with spring in the described cylinder body, spring is provided with piston, be provided with y-type seal ring between piston and the cylinder body, described dust keeper is welded on the bottom of cylinder body by nut, and the bottom of cylinder body is positioned at the nut weld and is provided with pore, be provided with weighting material in the groove of described nut, weighting material is provided with sheath.
The beneficial effects of the utility model are: owing to fully filtered out impurity such as airborne silt and dust, thereby cylinder body, piston, spring are difficult for because of former thereby early failures such as corrosion pluckings, y-type seal ring also can not produce the situation of premature wear because of entering of impurity such as silt, thereby prolonged the life-span of air chamber, guaranteed traffic safety.
Description of drawings
Fig. 1 is the structural representation of the piston type energy storage spring brake chamber of the utility model embodiment;
Fig. 2 is the partial enlarged drawing of dust keeper in the piston type energy storage spring brake chamber of the utility model embodiment.
Among the figure:
