Abstract
The utility model discloses a first secondary cup of an automobile hydraulic brake master cylinder with a secondary lip, comprising the first secondary cup body of the automobile master cylinder; the external ring of the cup body is provided with a first sealing secondary lip; the sealing secondary lip is added at the external side of the cup body; the secondary lip can play a secondary sealing effect when the leakage occurs to the master lip of the cup; the second sealing secondary lip of the internal ring can ensure that the stability is increased after the cup is loaded in the piston; as the first and second sealing secondary lips are added, a ring trough is added on the cup body between the two lips so as to eliminate the excessively large interference. Compared with the prior art, the first secondary cup has the advantages of improving the sealing performance and anti-wearing performance of the product and the assembly stability and prolonging the service life of the brake master cylinder.
Description
Technical field
The utility model relates to the rubber cup that a kind of hydraulic vehicle braking is used, and particularly a kind ofly is with secondary lip formula automobile hydraulic brake master first secontary cup.
Background technique
Hydraulic braking system for automobile utilizes the incompressible principle of liquid, when in that the legpower plate is stressed when promoting forward, by hydraulic pressure transfer pressure, thereby realizes the automobile brake effect.Leather cup belongs to safety member in the automobile braking master cylinder braking system, play a part crucial.Automobile master cylinder first secontary cup is positioned at brake master cylinder first piston rear end, prevents that brake fluid from leaking from the master cylinder rear portion.If brake fluid leaks, the part in the brake assembly can be corroded, and causes braking failure, causes the infringement of the person and property.The shortcoming of existing product is: product hermeticity can be poor, seal lip is fragile, poor durability.
Summary of the invention
The purpose of this utility model is: provide the secondary lip formula of band automobile hydraulic brake master first secontary cup of a kind of good airproof performance, long service life, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: structure comprises the bowl body of automobile master cylinder first secontary cup, is provided with the first sealing pair lip on the external circle of bowl.
The secondary lip formula of above-mentioned band automobile hydraulic brake master first secontary cup is provided with the second sealing pair lip on bowl body inner ring.
The secondary lip formula of above-mentioned band automobile hydraulic brake master first secontary cup is provided with annular groove on the bowl body between the first sealing pair lip and the second sealing pair lip.
The utility model increases the sealing pair lip in the external side of bowl, can produce under the situation of leaking at leather cup master lip, and this pair lip plays the effect that secondary seal is deposited.The second sealing pair lip of inner ring can guarantee that leather cup is packed into increases stability after inserting behind the piston.Since increased by the first and second sealing pair lips, excessive in order to eliminate interference, increase by an annular groove on the bowl body between the two.Therefore compare with prior art, the utlity model has the sealing and the anti-wear energy that improve product, and the stability of assembling, the brake master cylinder advantage in working life improved simultaneously.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Embodiment
Embodiment of the present utility model: make the bowl body 1 of automobile master cylinder first secontary cup, on bowl body 1 outer ring, produce the first sealing pair lip 2.According to the size of product outside dimension, specifically calculate and design the size of the first sealing pair lip 2, the size design of the first sealing pair lip 2 of present embodiment is at 0.8～1.5mm.
On bowl body 1 inner ring, produce the second sealing pair lip 3, can improve the stability behind the piston of packing into.In order to eliminate the interference influence that increases the sealing pair lip, on the bowl body 1 between the first sealing pair lip 2 and the second sealing pair lip 3, produce annular groove 4, as the space of stepping down of secondary lip.The wedge angle of each sealing pair lip is answered rounding or miter angle, and is convenient for assembly, and the effect that has guiding and reduce wear.
Claims (3)
1. be with secondary lip formula automobile hydraulic brake master first secontary cup for one kind, structure comprises the bowl body (1) of automobile master cylinder first secontary cup, it is characterized in that: be provided with the first sealing pair lip (2) on bowl body (1) outer ring.
2. the secondary lip formula of band according to claim 1 automobile hydraulic brake master first secontary cup is characterized in that: be provided with the second sealing pair lip (3) on bowl body (1) inner ring.
3. the secondary lip formula of band according to claim 1 and 2 automobile hydraulic brake master first secontary cup is characterized in that: be provided with annular groove (4) on the bowl body (1) between the first sealing pair lip (2) and the second sealing pair lip (3).
