Description
Technical field
The present invention relates to clutch release system field, in particular to a kind of wearing clutch hydraulic main cylinder and its shell structure.
Background technique
In existing wearing clutch hydraulic main cylinder, between the piston that can be moved axially in shell and the inner surface of shell one end
Hydraulic pressure room is formed, has helical spring in hydraulic pressure room, the both ends of helical spring are born against in piston and shell one end
Inner surface on, shell offers aperture on the position corresponding to hydraulic pressure room, and tapping is connected with oil pipe, oil pipe again with
Hydraulic slave cylinder is connected, and by aperture, the oil liquid in hydraulic pressure room can enter in hydraulic slave cylinder through oil pipe, drives clutch
Device separation.Specifically, mobile piston, overcomes the elastic resistance compressed spring of spring, and compression hydraulic pressure chamber, in pressure chamber
Oil liquid entered in hydraulic slave cylinder by aperture and oil pipe, driving release bearing is to driving clutch separation.In this bullet
During spring is compressed, spring is easy to happen bending, and due to the presence of aperture in hydraulic pressure room, spring curved in this way holds
It is easily stopped by the orifice part of aperture, continues to move to piston compressed spring, spring can be jumped out from aperture, and generate making an uproar for creak
Sound.
Summary of the invention
Problems solved by the invention is that spring deformation moves through noise problem when aperture.
To solve the above problems, the present invention provides a kind of shell structure of wearing clutch hydraulic main cylinder, including shell, it is provided with
Aperture on the shell, the aperture are used to be connected by oil pipe with hydraulic slave cylinder, and ribs, institute are provided in the aperture
The axial direction that ribs are stated along the shell extends on opposite other side bore edges from the side bore edges of the aperture,
The corresponding position that the ribs are located axially at the aperture two sides with the shell is flush.
When it is implemented, the ribs have one, the centre of the aperture is arranged in a ribs, and opens described
Hole is divided into two opening portions.
The present invention also provides a kind of wearing clutch hydraulic main cylinder, including shell, it is disposed in the housing can be along the shell
The mobile piston of axial direction, be formed between the piston and the inner surface of described shell one end hydraulic pressure room, two
End bears against the spring on the inner surface of the piston Yu described shell one end and being located in the hydraulic pressure room, described
Shell offers aperture on the position of the correspondence hydraulic pressure room, which is used to pass through oil pipe and hydraulic slave cylinder phase
Even, be provided with ribs in the aperture, the ribs along the shell axial direction from the side hole edge of the aperture
Edge extends on opposite other side bore edges, and the ribs and the shell are located axially at the aperture two sides
Corresponding position be flush, the ribs can guide the movement for supporting the spring in hydraulic pressure room.
When it is implemented, the ribs have one, the centre of the aperture is arranged in a ribs, and opens described
Hole is divided into two opening portions.
When it is implemented, the aperture is close to described shell one end.
Compared with prior art, technical solution of the present invention has the advantage that
Ribs are provided in the aperture of shell, ribs extend along the axial direction of shell from the side bore edges of aperture
Onto opposite other side bore edges, and the corresponding position that ribs and shell are located axially at aperture two sides is mutually neat
Flat, application external force in this way is come when moving piston, even if that deformation occurs is mobile for spring, but in process aperture, due to ribs
Setting, enables ribs to guide the movement of support spring, spring will not be fallen into the aperture of aperture, therefore avoid creak
Spring noise.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view one that hydraulic main cylinder of the invention is splitted from centre；
Schematic cross-sectional view two that Fig. 2 is hydraulic main cylinder of the invention to be splitted from centre, wherein Fig. 1 and Fig. 2 splits direction
It is perpendicular；
Fig. 3 is the cutaway enlargement diagram of individual shell in Fig. 2.
Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Referring to Fig.1, Fig. 2, wearing clutch hydraulic main cylinder, including shell 1, piston 2, hydraulic pressure room 3, spring 4,2 energy of piston
Enough axial directions along shell 1 are movably arranged in shell 1, form hydraulic pressure between the inner surface of 1 one end of piston 2 and shell
Power room 3, spring 4 are located in hydraulic pressure room 3, and against on the piston 2, the other end is resisted against 1 one end of shell for one end of spring 4
On inner surface, spring 4 offers aperture 6 and 7, aperture 6 is used as high pressure oil for providing piston 2 elastic-restoring force on shell 1
Hole is used for the (not shown) that is connected by oil pipe with hydraulic slave cylinder, therefore the position of aperture 6 corresponds to hydraulic pressure room 3,
In Fig. 2, the position of aperture 6 also proximates 1 one end of shell, and aperture 7 is used as low pressure oil hole, (does not show in figure for being connected with oil storage tank
Out).
In figs 2 and 3, be provided with ribs 5 in aperture 6, ribs 5 along shell 1 axial direction from the side of aperture 6
Bore edges extend on opposite other side bore edges, and the quantity of ribs 5 can be one or more, in the present embodiment, such as
Shown in Fig. 3, ribs 5 only have one, and the centre of aperture 6 is arranged in a ribs 5, and aperture 6 is divided into two openings
Part.The corresponding position that ribs 5 are located axially at 6 two sides of aperture with shell 1 is flush, and piston 2 mobile in this way is pressed
When contracting spring 4, even if 4 deformation of spring is mobile, but when by aperture 6, due to the setting of ribs 5, enable ribs 5
The movement of support spring 4 is guided, spring 4 will not be fallen into the aperture of aperture 6, therefore avoid the noise of creak.It is being applied to
When external force on piston 2 is eliminated, under the elastic-restoring force effect of spring 4, piston 2 resets, and same ribs 5 can guide at this time
The reset movement of support spring 4 basically will not produce spring noise.
Although present disclosure is as above, present invention is not limited to this.Anyone skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
