Abstract
The utility model discloses a clutch master cylinder flange structure with prevent moment decay function. Bolts are fixed on two sides of the flange end face of the clutch main cylinder, the flange and the bolts are integrally formed, and an annular boss with a fixed height is arranged at the joint of the bolts and the flange; and the flange mounting end face at the joint of the bolt and the flange is provided with a liner, liner mounting holes for the bolt to pass through are arranged on two sides of the liner, and the aperture of each liner mounting hole is larger than the outer diameter of the annular boss of the bolt. The utility model discloses have and prevent moment decay function, can effectively avoid being leaded to the nut to tighten moment and decline gradually because of the unrecoverable deformation that the liner produced after by long-term compression, improved the security.
Description
Technical Field
The utility model relates to a part of clutch master cylinder has especially related to a clutch master cylinder flange structure with prevent moment decay function.
Background
With the development of the automotive industry and plastic technology, integrated flange structures are increasingly being used in large host plants. According to the traditional integrated flange structure, the bolts at the end of the flange mounting surface do not have annular bosses, and after the gasket is mounted and is in a compressed state for a long time, the nut tightening torque is easy to decline gradually due to unrecoverable deformation of the gasket, so that a clutch main cylinder is loosened, and potential safety hazards are easily caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a clutch master cylinder flange structure with prevent moment decay function is provided exactly.
In order to solve the technical problem, the utility model adopts the following technical scheme:
bolts are fixed on two sides of the flange end face of the clutch main cylinder, the flange and the bolts are integrally formed, and an annular boss with a fixed height is arranged at the joint of the bolts and the flange; and the flange mounting end face at the joint of the bolt and the flange is provided with a liner, liner mounting holes for the bolt to pass through are arranged on two sides of the liner, and the aperture of each liner mounting hole is larger than the outer diameter of the annular boss of the bolt.
The flange is made of plastic.
The bolt material is a metal material.
The gasket material is a foaming material such as EPDM.
The flange and the bolt are integrated through injection molding.
The utility model has the advantages that:
the utility model discloses a clutch master cylinder flange structure has the moment attenuation function of preventing, can effectively avoid leading to the nut to tighten moment and decline gradually because of the unrecoverable deformation that the liner produced after being compressed for a long time to the security has been improved.

Fig. 1 is a schematic view of the connection structure of the flange, the gasket and the bolt of the present invention.
Fig. 2 is a front view of the flange of the present invention.
Fig. 3 is a partial detailed view of fig. 2.
Fig. 4 is an axial view of the flange of the present invention.
Fig. 5 is an isometric view of the gasket of the present invention.
In the figure: flange 1, gasket 2, bolt 3, annular boss 4, gasket mounting hole 5.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1, bolts 3 are fixed on two sides of the end face, close to the push rod end, of a flange 1 of the clutch master cylinder, the flange 1 and the bolts 3 are integrally molded, and as shown in fig. 2 and 3, an annular boss 4 with a fixed height is arranged at the joint of the bolts 3 and the flange 1 and is used for bearing a nut tightening torque.
As shown in fig. 4 and 5, a gasket 2 is assembled on the mounting end face of the flange 1 at the joint of the bolt 3 and the flange 1, the gasket is used for reducing noise, gasket mounting holes 5 for the bolt 3 to pass through are arranged on two sides of the gasket 2, and the diameter of each gasket mounting hole 5 is larger than the outer diameter of the bolt annular boss 4.
In order to avoid the noise problem, the invention has to design a liner on the flange mounting surface of the clutch main cylinder for reducing the noise, and simultaneously, the designed liner mounting hole is larger than the bolt annular boss. When the nut is tightened, the tightening torque completely acts on the bolt annular boss, so that the gradual decline of the tightening torque of the nut caused by the unrecoverable deformation generated after the gasket is compressed for a long time can be effectively avoided, and the safety is improved.
The utility model discloses flange simple structure, it is convenient to use, can effectively avoid leading to the nut to tighten moment and decline gradually because of the unrecoverable deformation that the liner produced after being compressed for a long time, has improved the installation security of clutch master cylinder, is favorable to using widely.
