Description
Technical Field
The utility model relates to a pre-charge oil formula clutch hydraulic system especially relates to a buckle formula oil cup lid structure for pre-charge oil formula clutch hydraulic system.
Background
When the traditional clutch hydraulic system is used for assembling the whole automobile, a clutch main cylinder, a working cylinder, a high-pressure hard pipe and the like need to be connected together firstly, and then vacuum filling is carried out, so that the assembling efficiency is influenced, and time and labor are wasted. In recent years, more and more host factories adopt pre-oil-filled integrated clutch hydraulic systems, and in the traditional pre-oil-filled integrated clutch hydraulic systems, an oil cup cover usually adopts a threaded mounting structure, fixed mounting torque needs to be specified during assembly, and the system is complex in operation and not easy to use for a long time.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem existing in the background technical field, the utility model aims to provide a buckle formula oil cup lid structure for prefilling oil filled type clutch hydraulic system.
In order to solve the technical problem, the utility model discloses a technical scheme as follows:
the utility model comprises an oil cup cover sealing ring, a sealing ring cover and an oil cup; the sealing ring cover is arranged inside the oil cup cover sealing ring, and the oil cup cover sealing ring provided with the sealing ring cover is arranged in the oil cup hole in an interference fit manner.
And the top of the sealing ring cover is provided with a vent hole communicated with the atmospheric pressure.
The inner ring of the opening of the oil cup cover sealing ring is provided with an annular groove for installing a sealing ring cover, a sealing ring groove for installing an oil cup is arranged below the annular groove, a notch for discharging brake fluid outwards when the oil cup cover sealing ring is installed is arranged below the sealing ring groove, and a convex hull structure with elastic deformation is arranged on the lower portion of the oil cup cover sealing ring.
The breach has a plurality ofly and is circumference evenly arranged.
The convex hull structure is provided with four semi-cylindrical grooves, and when brake fluid in the clutch hydraulic system is gradually lost and vacuum is generated in the clutch hydraulic system, the semi-cylindrical grooves can be ejected out under the action of atmospheric pressure.
The oil cup cover sealing ring is made of EPDM materials.
The material of the sealing ring cover is a polymer composite material.
The utility model has the advantages that:
the utility model discloses an oil cup cover installs fast, has solved traditional pre-filled oil cup cover installation difficulty, the problem that the operation is wasted time and energy.
