Abstract
A kind of clutch master cylinder containing novel piston assembly, including clutch master cylinder housing, piston component and stop collar, piston component slides axially in clutch master cylinder housing by stop collar is spacing, described piston component includes that piston, push rod and push rod connect seat, main apron, apron seat and secondary apron it is provided with between piston and clutch master cylinder housing, the head of piston is provided with the chamfering for the logical oil of aerofluxus, and this chamfering arranges a circle around piston axis, and push rod connects seat by push rod and is arranged on the tail of piston；Assemble simpler, save assembly process and material cost, it is ensured that piston coaxial degree; push rod, push rod connect seat, piston be linked and packed more efficient and convenient; increasing the stability of product, the chamfering of the head of piston coordinates more smooth and easy with main apron, will not scratch apron.
Description
Technical field
This utility model relates to a kind of clutch master cylinder containing novel piston assembly.
Background technology
In the prior art, clutch master cylinder includes clutch master cylinder housing, piston component and stop collar, and piston component leads to
Cross that stop collar is spacing to slide axially in clutch master cylinder housing.But piston component have employed steel bushing, steel bushing precision and technique and wants
Asking high, buying and production cost are high.It is and steel bushing is connected seat and uses fourth of the twelve Earthly Branches pressure to install with push rod, yielding after the pressure of the steel bushing fourth of the twelve Earthly Branches,
Cause axiality inconsistent, affect product service life and performance, and after deforming, cause piston in clutch master cylinder housing
Matched in clearance is bad, produces catching phenomenon, whole assembly will be caused the when of serious to scrap.
Utility model content
In view of technical problem present in background technology, this utility model is solved the technical problem that aiming to provide one contains
The clutch master cylinder of novel piston assembly.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that:
A kind of clutch master cylinder containing novel piston assembly, including clutch master cylinder housing, piston component and stop collar, lives
Plug assembly slides axially in clutch master cylinder housing by stop collar is spacing, it is characterised in that: described piston component includes living
Plug, push rod and push rod connect seat, are provided with main apron, apron seat and secondary apron between piston and clutch master cylinder housing, piston
Head is provided with the chamfering for the logical oil of aerofluxus, and this chamfering arranges a circle around piston axis, and push rod connects seat by push rod and is arranged on
The afterbody of piston.
Described piston uses aluminum material.
The afterbody of described piston is provided with and connects, for push rod, the installation cavity that seat is installed, and the opening part of installation cavity is provided with restriction push rod
Connect the spacing barb that seat is put.
The beneficial effects of the utility model are, assemble simpler, save assembly process and material cost, it is ensured that piston
Axiality, push rod, push rod connect seat, piston be linked and packed more efficient and convenient, increase product stability, the head of piston
Chamfering coordinate more smooth and easy with main apron, will not scratch apron.
This utility model compared with prior art has substantive distinguishing features and progress.
Accompanying drawing explanation
Embodiment of the present utility model and the relevant details of embodiment and operation principle are described below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of piston component in this utility model.
Detailed description of the invention
Seeing accompanying drawing, in present embodiment, a kind of clutch master cylinder containing novel piston assembly, including clutch master cylinder shell
Body, piston component and stop collar.Piston component slides axially in clutch master cylinder housing by stop collar is spacing, and stop collar leads to
Cross supersonic welding and be connected on clutch master cylinder housing cylinder holes opening part, O type is set between stop collar and clutch master cylinder housing and seals
Circle 6.Piston component includes that piston, push rod and push rod connect seat (or claiming push rod locking bed).Piston and clutch master cylinder housing it
Between be provided with main apron, apron seat and secondary apron.Piston is a rotary body, and the head of piston is provided with chamfering, and this chamfering is around piston shaft
Line arranges a circle, and chamfering is for the logical oil of aerofluxus.The chamfering of the head of piston coordinates more smooth and easy with main apron, will not scratch and work
The apron that plug coordinates.
Push rod connects seat by push rod and is arranged on the afterbody of piston.Piston can use aluminum material.
The afterbody of piston is provided with and connects, for push rod, the installation cavity that seat is installed, and the opening part of installation cavity is provided with spacing barb, limit
Position barb limits push rod and connects the position of seat.The bulb of push rod being placed on the when of assembling push rod and connects in seat, push rod connects
Seat uses plastics, and such as elastoplast, push rod connects in the installation cavity that seat fills in piston again.
Assemble simpler, save assembly process and material cost, it is ensured that piston coaxial degree, push rod, push rod connection seat,
Being linked and packed of piston is more efficient and convenient, increases the stability of product.
