Abstract
A kind of master cylinder of the component containing novel piston, piston component is set in the inner cavity of its housing, oil inlet passage is set on housing, the piston main body of piston component is separately set as secondary piston and rear piston, between secondary piston and rear piston by connector connect and secondary piston it is opposite after piston fore-aft travel, the front side setting return spring of secondary piston, the front end of piston is step column afterwards, step column narrows setting, and the rear side of step column is the step groove on rear piston, fillet setting at the openning of oil inlet passage；The piston main body of separate structure is convenient for assembling, the long easy discontinuity of one-piece piston main body is avoided to generate unilateral stress, overcome the problems, such as because the unilateral stress friction serious service life is too short, separate structure is when piston main body discontinuity, piston can unilateral stress after only, the friction to housing is reduced in secondary piston activity adjustment position relatively, particularly adjusts radial position.Apron is easy for installation, avoids apron stretching transition, it is ensured that apron sealing performance.
Description
Technical field
The utility model is related to master cylinders.
Background technology
Master cylinder（Master Cylinder）Also referred to as brake main oil（Gas）, its main function is to push brake fluid
（Or gas）It is transmitted among each brake cylinder and pushes piston.
Piston, which is located in the housing cavity of master cylinder, to be axially moved, and piston is long, when piston is axially moved in housing
Easy discontinuity, it is uneven that unilateral stress causes piston to rub with housing, influences the service life of housing and piston main body, especially
It is housing（That is cylinder body）Service life.The long apron assembling caused on piston of piston is difficult, particularly in intermediate apron, assembling
When need stretch apron, apron excessive tensile deformation may tear or influence sealing performance, product qualification rate is caused to reduce.Housing
Oil inlet passage openning at have wedge angle, when assembling piston component, there are the risks that wedge angle scratches O-ring seal and apron.
Utility model content
In view of technical problem present in background technology, the technical issues of the utility model solves, is intended to provide one kind and contains
The master cylinder of novel piston component.
In order to solve the above technical problems, the utility model adopts the following technical scheme：
A kind of master cylinder of component containing novel piston includes housing, piston component, housing is equipped in the inner cavity of housing
Oil inlet passage is equipped with, piston component includes piston main body, it is characterised in that：The piston main body be separately set as secondary piston and
Piston afterwards, secondary piston are located at rear pistons front sides, between secondary piston and rear piston by connector connect and secondary piston it is opposite after
Piston fore-aft travel, the front side setting return spring of secondary piston, the front end of rear piston is step column, and step column narrows setting,
The rear side of step column is the step groove on rear piston, fillet setting at the openning of oil inlet passage.
Connector uses trip bolt, and secondary piston is equipped with the mounting hole passed through for connector, secondary piston opposite joints
It is radially movable.
Secondary piston and rear piston are equipped with the auxiliary section for matching and sliding back and forth in housing cavity.
The beneficial effects of the utility model are, using the piston main body of separate structure, convenient for assembling, the piston of separate structure
The secondary piston of main body and rear piston relatively can be movable, the long easy discontinuity of one-piece piston main body avoided to generate unilateral
Stress is overcome because the friction of unilateral stress is serious（Housing and piston main body）The problem of service life is too short, separate structure work as piston main body
During discontinuity, only after piston can unilateral stress, secondary piston friction of the activity adjustment position reduction to housing relatively, especially
It is adjustment radial position.Apron is easy for installation, avoids apron stretching transition, it is ensured that apron sealing performance.Therefore, the utility model
There is substantive distinguishing features and progress compared with prior art.
Description of the drawings
The embodiment of the utility model and the related details and operation principle of embodiment are described below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of master cylinder in background technology.
Specific embodiment
Referring to attached drawing, in present embodiment, a kind of master cylinder of component containing novel piston includes housing 1, housing 1
Inner cavity in be equipped with piston component, housing 1 be equipped with oil inlet passage 3, piston component include piston main body.It, will in the present embodiment
Piston main body is separately set as secondary piston 4 and rear piston 5, using the piston main body of separate structure, is easily installed.4 He of secondary piston
Piston 5 is equipped with the auxiliary section for matching and sliding back and forth in 1 inner cavity of housing afterwards（Such as the protrusion at edge）, it is so as to secondary piston and living afterwards
Fill in fore-aft travel（Slide axially）.Secondary piston 4 is located at rear 5 front side of piston, passes through fastener 6 between secondary piston 4 and rear piston 5
Connection and the relatively rear piston fore-aft travel of secondary piston, the front side setting return spring 7 of secondary piston 4.The front end of piston is afterwards
Step column 51, step column 51 narrow setting（I.e. outer diameter becomes smaller）, the rear side of step column is the step groove 52 on rear piston, facilitates skin
During circle 52 is arranged on step groove, and apron 52 is without excessive and long time-stretching.Justify at the openning of oil inlet passage 3
Angle is set, and when avoiding assembling piston component, openning scratches sealing ring and apron.Secondary piston will have return spring and the rear piston mutual
Effect is maintained at carry out activity in housing.Secondary piston is equipped with front and rear through hole, easy to process.Connector 6 uses trip bolt,
Secondary piston 4 is equipped with the mounting hole passed through for connector 6, and secondary piston opposite joints are radially movable, therefore mounting hole aperture is big
In connector, so as to radially movable.Separate structure when piston main body discontinuity, only after piston can unilateral stress, it is preceding
The friction to housing is reduced in piston activity adjustment position relatively, particularly adjusts radial position, avoids one-piece piston main body mistake
Long easy discontinuity generates unilateral stress, overcomes because the friction of unilateral stress is serious（Housing and piston main body）Service life is too short
Problem.
