Abstract
The invention relates to a clutch hydraulic main cylinder and a shell structure thereof, wherein a support rib is arranged in an opening of a shell, the support rib extends from one side hole edge of the opening to the other opposite side hole edge along the axial direction of the shell, and the support rib is flush with the corresponding position of the shell on two sides of the opening in the axial direction, so that when an external force is applied to move a piston, even if a spring deforms and moves, the support rib can guide the movement of the support spring when passing through the opening, and the spring cannot fall into an opening of the opening, thereby avoiding creaking spring noise.
Description
Technical field
The present invention relates to clutch release system field, particularly a kind of wearing clutch hydraulic main cylinder and shell construction thereof.
Background technique
In existing wearing clutch hydraulic main cylinder, hydraulic pressure room is formed between the piston that can move axially in housing and the internal surface of shell one end, hydraulic pressure has helical spring in room, helical spring two ends are resisted against on the internal surface of piston and shell one end respectively, housing offers perforate on the position corresponding to hydraulic pressure room, tapping is connected with oil pipe, oil pipe is connected with hydraulic slave cylinder again, pass through perforate, fluid in hydraulic pressure room can enter in hydraulic slave cylinder through oil pipe, and driving clutch is separated.Specifically, mobile piston, overcomes the elastic resistance Compress Spring of spring, and compression hydraulic pressure chamber, the fluid in pressure chamber enters in hydraulic slave cylinder by perforate and oil pipe, drives release bearing thus driving clutch separation.At this spring by the process compressed, spring easily bends, due to the existence of perforate in hydraulic pressure room, spring bending so is easily stopped by the orifice part of perforate, continue mobile piston Compress Spring, spring can be jumped out from perforate, and produces the noise of creak.
Summary of the invention
The problem that the present invention solves is that spring deformation moves through noise problem during perforate.
For solving the problem, the invention provides a kind of shell construction of wearing clutch hydraulic main cylinder, comprise housing, offer perforate on the housing, this perforate is used for being connected with hydraulic slave cylinder by oil pipe, ribs is provided with in described perforate, described ribs extends to relative opposite side bore edges along the axial direction of described housing from the side bore edges of described perforate, and the corresponding position that described ribs and described housing are located axially at described perforate both sides flushes.
During concrete enforcement, described ribs has one, and a ribs is arranged on the centre of described perforate, and described perforate is divided into two open parts.
The present invention also provides a kind of wearing clutch hydraulic main cylinder, comprise housing, being arranged on can along the piston of the axial direction movement of this housing in described housing, hydraulic pressure room between the internal surface being formed in described piston and described shell one end, the internal surface that two ends are resisted against described piston and described shell one end is respectively arranged in the spring of described hydraulic pressure room, described housing offers perforate on the position of the described hydraulic pressure room of correspondence, this perforate is used for being connected with hydraulic slave cylinder by oil pipe, ribs is provided with in described perforate, described ribs extends to relative opposite side bore edges along the axial direction of described housing from the side bore edges of described perforate, the corresponding position that described ribs and described housing are located axially at described perforate both sides flushes, described ribs can the movement of spring in hydraulic pressure room described in guide support.
During concrete enforcement, described ribs has one, and a ribs is arranged on the centre of described perforate, and described perforate is divided into two open parts.
During concrete enforcement, described perforate is near described shell one end.
Compared with prior art, technological scheme of the present invention has the following advantages:
Ribs is provided with in the perforate of housing, ribs extends to relative opposite side bore edges along the axial direction of housing from the side bore edges of perforate, and the corresponding position that ribs and housing are located axially at perforate both sides flushes, when such applying external force carrys out mobile piston, even if spring generation deformation is moved, but through perforate, due to the setting of ribs, make ribs can the movement of guide support spring, spring can not be fallen in the aperture of perforate, therefore avoids the spring noise of creak.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic one that hydraulic main cylinder of the present invention is cut open from centre;
Fig. 2 is the cross-sectional schematic two that hydraulic main cylinder of the present invention is cut open from centre, wherein Fig. 1 and Fig. 2 to cut direction open perpendicular;
Fig. 3 be housing independent in Fig. 2 analyse and observe enlarged diagram.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2, wearing clutch hydraulic main cylinder, comprise housing 1, piston 2, hydraulic pressure room 3, spring 4, piston 2 can be arranged within the case 1 movably along the axial direction of housing 1, hydraulic pressure room 3 is formed between the internal surface of piston 2 and housing 1 one end, spring 4 is arranged in hydraulic pressure room 3, one end of spring 4 is against on the piston 2, the other end is resisted against on the internal surface of housing 1 one end, spring 4 is for providing piston 2 elastic-restoring force, housing 1 offers perforate 6 and 7, perforate 6 is as high pressure oilhole, for the (not shown) that to be connected with hydraulic slave cylinder by oil pipe, therefore corresponding hydraulic pressure room 3, the position of perforate 6, in fig. 2, the position of perforate 6 is also near housing 1 one end, perforate 7 is as low pressure oilhole, for the (not shown) that is connected with oil storage tank.
In figs 2 and 3, ribs 5 is provided with in perforate 6, ribs 5 extends to relative opposite side bore edges along the axial direction of housing 1 from the side bore edges of perforate 6, the quantity of ribs 5 can be one or more, in the present embodiment, as shown in Figure 3, ribs 5 only has one, article one, ribs 5 is arranged on the centre of perforate 6, and perforate 6 is divided into two open parts.The corresponding position that ribs 5 and housing 1 are located axially at perforate 6 both sides flushes, during such mobile piston 2 Compress Spring 4, even if spring 4 deformation is moved, but when through perforate 6, due to the setting of ribs 5, make ribs 5 can the movement of guide support spring 4, spring 4 can not be fallen in the aperture of perforate 6, therefore avoids the noise of creak.When applying external force on the piston 2 and eliminating, under the elastic-restoring force effect of spring 4, piston 2 resets, and now the reset movement of same ribs 5 meeting guide support spring 4, can not produce spring noise substantially.
Although the present invention discloses as above, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
