Mating surface between end 11 and the first end 31 has preferable sealing effect.
In the present invention, the specific set-up mode of the ring packing muscle 311 and the annular mounting recess 111 is not limited,
For example, it may be the ring packing muscle 311 is set to the master cylinder set, the annular mounting recess 111 is set to institute
Sealing shroud 3 is stated, the material of the usual ring packing muscle 311 is flexible preferable material, close for the ease of the annular is arranged
Muscle 311 is sealed, in the embodiment of the present invention, the ring packing muscle 311 is convexly equipped in the inner sidewall of the first end 31, and the ring
For shape sealing bar 311 with the sealing shroud 3 in being wholely set, the annular mounting recess 111 is set to the opening of the Clutch main cylinder 1
The lateral surface at end 11, while making sealing shroud 3, ring packing muscle 311 described in straight forming is saved processing procedure, is convenient for
Molding, in the fabrication process, annular mounting recess 111 described in straight forming is also relatively simple for the Clutch main cylinder 1.
The push rod 2 is during movable, in order to guarantee that first end 31 and the second end 33 of the sealing shroud 3 can divide
It is preferably not in sealing contact with the Clutch main cylinder 1 and the push rod 2, the first end 31 of the sealing shroud 3 and second set described
Need to limit the open end 11 of the Clutch main cylinder 1, the second end 33 needs to be limited in the installation end 22 of the push rod 2, tool
Body, the lateral surface of the open end 11 is equipped with annular spacing groove 112, and the annular spacing groove 112 has backwards to described second
First stop surface 1121 at end 33, the internal diameter of the first end 31 of the sealing shroud 3 is relative to the adjusting section 32 in reduction setting
To form first confined planes 312 for being directed toward the second end 33, first confined planes 312 and first stop surface 1121
It abuts, the first end 31 is enabled preferably to be limited in the open end 11 of the Clutch main cylinder 1, there is preferable effect.
In addition, the installation end 22 includes being connected to the first segment of the movable end 21, for being connected to clutch pedal
Second segment and the construction section 22a between the first segment and second segment, the relatively described first segment of construction section 22a
And the second segment diametrically reduces setting, the internal diameter of the second end 33 of the sealing shroud 3 is in subtract relative to the adjusting section 32
Small setting, the second end 33 are mounted in the construction section 22a, by the construction section 22a to the of the sealing shroud 3
Two ends 33 can preferably limit, and have preferable effect.
It should be noted that two kinds of above-mentioned limit methods can select a selection in the embodiment of the present invention, it can also be same
When select so that limit effect is preferable.
It is rotated between the sealing shroud 3 and the push rod 2 to reduce to the greatest extent, so that the sealing shroud 3 and the push rod 2
Between obtain compared with sealing effect, the lateral surface of the construction section 22a is equipped with rotation stop plane 221, the second end 33 it is interior
Side wall corresponds to the rotation stop plane 221 equipped with rotation stop protrusion 331, the medial surface of the rotation stop protrusion 331 and the rotation stop plane
221 push against cooperation, and rotation stop cooperates between the sealing shroud 3 and the push rod 2, further limit the sealing shroud 3 in institute
The movement on push rod 2 is stated, so that the sealing shroud 3 has preferable sealing effect, it should be noted that the rotation stop protrusion
331 are correspondingly arranged with the rotation stop plane 221, and are arranged two, are symmetrical set, and have better rotation stop effect.
The sealing shroud 3 can generate variation with volume in the active procedure of the push rod 2, in order to balance the sealing shroud 3
Interior air pressure, in embodiments herein, the lateral surface of the construction section 22a is additionally provided with helicla flute 222, the helicla flute 222
Be connected to the inner cavity of the sealing shroud 3, the second end 33 of the sealing shroud 3 is equipped with air hole 332, the air hole 332 with it is described
Helicla flute 222 is connected, and can set elongated hole for the air hole 332, and the extending direction along the push rod 2 is arranged, when
The setting position of the right elongated hole needs to avoid the rotation stop protrusion 331 and is arranged, and the number of the elongated hole is also unrestricted
System, the helicla flute 222 increase the path that dust enters the seal chamber inner cavity, and the elongated hole passes through the helicla flute
The inner cavity of the 222 connection sealing shrouds 3, balances the air pressure in the sealing shroud 3, has preferable effect.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
