Abstract
The invention relates to a compensation hole and center valve type brake master cylinder opening sealing structure and belongs to the technical field of automobile braking systems. The inner end of a first piston is slidably connected with a master cylinder body by virtue of a first contact point and a second contact point; an oil inlet hole of the master cylinder body is positioned between the first contact point and the second contact point; a sealing ring groove is formed in the master cylinder body which is in sliding connection with the second contact point of the first piston; the outer lip of a secondary cup is hermetically connected with the sealing ring groove, and the inner lip of the secondary cup is hermetically connected with the outer diameter of the second contact point of the first piston. The sealing structure disclosed by the invention has the advantages that the structure is novel, the quantity of parts is small, the probability of a failure mode occurring is reduced, and the operational performance of the product is greatly improved; the first piston is contacted with the master cylinder body through the two contact points, and the guide distance of the first piston during moving is long, so that the motion performance of the product is stable, the sealing characteristics of the compensation hole and center valve type brake master cylinder opening are further optimized, the product sealing performance is effectively improved, and the product weight is lightened.
Description
Technical field
The invention belongs to brake system of car technical field, is one kind to existing compensation hole and center valve type brake main cylinder mouth
The improvement of part sealing structure.
Background technology
The sealing parts in the compensation hole and centre valve master cylinder oral area that are currently used for automobile brake have：Butterfly reed,
Back-up ring, O-ring seal, secondary leather cup, spacing ring and check ring, these sealing parts form mouth with Master cylinder body and first piston
Part sealing structure, as the parts for sealing are more, once damaging occur in one of parts, then and brake fluid will be from system
Dynamic master cylinder flows to booster, causes brake fluid to be lost in, brake failure, serious threat to life safety；And first piston and master cylinder
The contact position of body is shorter and is one, makes guiding apart from short, causes the exercise performance of product unstable, so as to affect sealing
Energy.
Content of the invention
The present invention provides a kind of compensation hole and center valve type brake main cylinder oral area sealing structure, to solve zero because sealing
Part is more, fragile, and first piston is shorter with the contact position of Master cylinder body and is one, makes guiding apart from short, causes product
Exercise performance unstable, so as to affect the problem of sealing property.
The technical solution used in the present invention is：The inner end of first piston is by the first contact position and the second contact position and master cylinder
Body is slidably connected, and Master cylinder body fuel feed hole is being contacted with the second of first piston Wei Yu the first contact position and the second contact position between
There is closure gasket groove on the Master cylinder body that place is slidably connected, outer lip and the closure gasket groove of secondary leather cup are tightly connected, interior lip and first
Second contact position outside diameter seal connection of piston.
It is an advantage of the invention that structure is novel, by changing the structure of Master cylinder body and first piston, with a rubber cup
Replace butterfly reed, back-up ring, O-ring seal, secondary leather cup, spacing ring and these parts of check ring of original structure, due to zero
Number of packages amount is few, reduces the probability of failure mode generation, and the performance of product is greatly promoted；First piston by two with master cylinder
Body is contacted, and the guiding distance of first piston in motion makes product exercise performance more stable, further Optimization Compensation Kong He center
The sealing characteristics of valve type master cylinder oral area, effectively improve product sealing efficiency, alleviate product weight.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The inner end of first piston 3 is slidably connected with the second contact position 302 and Master cylinder body 1 by the first contact position 301, master cylinder
Body fuel feed hole 101 Wei Yu the first contact position 301 and the second contact position 302 between, in the second contact position 302 with first piston 3
Have closure gasket groove 102 on the Master cylinder body being slidably connected, the outer lip of secondary leather cup 2 and closure gasket groove 102 are tightly connected, interior lip with
Second contact position, the 302 outside diameter seal connection of first piston 3.
Claims (1)
1. one kind compensates hole and center valve type brake main cylinder oral area sealing structure, it is characterised in that：The inner end of first piston passes through
First contact position is slidably connected with the second contact position and Master cylinder body, and Master cylinder body fuel feed hole is located at the first contact position and the second contact position
Between, have closure gasket groove on the Master cylinder body that the second contact position with first piston is slidably connected, the outer lip of secondary leather cup with close
Seal ring groove is tightly connected, interior lip is connected with the second contact position outside diameter seal of first piston.
