Description
Technical field
This utility model relates to a kind of auto parts machinery, especially relates to a kind of single cylinder bicavate master cylinder.
Background technology
Master cylinder is generally again brake pump, it it is the critical component in brake system of car, its Main Function is that the effect by pedal force promotes the piston in master cylinder to move forward, master cylinder pressure chamber is made to produce hydraulic pressure, again through the oil-out of master cylinder to the brakes delivery hydraulic pressure of car load, thus realizing the brake function of automobile.The problems such as the master cylinder of prior art China commonly uses tandem double-piston structure and relates to, and it is complicated that the master cylinder ubiquity of this structure structure, fragile, inconvenience maintenance.
Utility model content
For solving the problems referred to above, the utility model proposes a kind of simple in construction, long service life, it is simple to the single cylinder bicavate master cylinder of maintenance.
This utility model be the technical scheme is that a kind of single cylinder bicavate master cylinder, including cylinder body, cylinder body is provided with oil-in, the inside of cylinder body is oil pocket, piston component it is provided with in oil pocket, the outer end of piston component is connected to the push rod stretching out outside cylinder body, rear end in described cylinder body is provided with a cavity, piston body the inner of described piston component has the ennation extending in cavity and being separated into by oil pocket the first oil pocket and the second oil pocket, it is provided with spring between ennation and cavity rear wall, the rear end of described cylinder body is provided with two oil-outs communicated respectively with the first oil pocket and the second oil pocket, described oil-in is provided with two, and the both sides laying respectively at cylinder body communicate with the first oil pocket and the second oil pocket.
Further, it is provided with fairlead between oral area and the push rod of described cylinder body.
Further, described fairlead is provided with pilot seal circle.
Further, described oil-out is provided with fuel tap.
Further, described oil-out lays respectively at the both sides of cavity.
Compared with prior art, it has the advantages that this utility model
Single cylinder bicavate master cylinder of the present utility model makes oil pocket be separated into double; two oil pocket by the extended structure of piston body, without designing two piston components, effectively simplify overall structure, easily facilitate maintenance, service life is also longer than traditional double-piston master cylinder simultaneously, easily facilitates manipulation.
