Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
In a kind of embodiment, a kind of annular piston assembly, as shown in Figure 3, comprise annular piston body 1 and anti-wear gasket 10, described annular piston body 1 comprises the outer wall that is positioned at described annular piston and 4 grooves 9 on the internal face, described anti-wear gasket 10 is fixed in the described groove 9, and the hardness of described anti-wear gasket is less than the hardness of described annular piston body.In this embodiment, further disclosed a kind of clutch release bearing, as shown in Figure 4, comprising: cylinder body 2, guard shield 3, guard shield fixing frame 4, primary seal circle 5, spring 6, bearing 7 and annular piston assembly as shown in Figure 3.In this embodiment, described cylinder body 2 is aluminum material.Apparently, the clutch release bearing of other structures, material carries out combination in the annular piston component technology that those of ordinary skills can be disclosed with the utility model and the prior art, forms the new embodiment in the utility model protection domain.
In this embodiment, the position of easily wearing and tearing at described annular piston assembly arranges several grooves, though be 4 grooves in this embodiment, but one of ordinary skill in the art will appreciate that, according to different concrete industrial requirements, the groove that can 1 ~ 10 diverse location be set at outer wall and/or the internal face of described annular piston.Because the hardness of described anti-wear gasket is less than the hardness of described annular piston body, therefore when possible wearing and tearing took place, the wearing and tearing of relatively large amount can take place in described anti-wear gasket, and the wear extent of described annular piston and described cylinder body is less.When described clutch release bearing is overhauled, only need change anti-wear gasket and get final product, need not to change described annular piston body 1 and/or described cylinder body 2.
In this embodiment, described anti-wear gasket is preferably elastic material, is convenient to described anti-wear gasket is fixed in the described groove, makes things convenient for processing and assembling.
In this embodiment, described anti-wear gasket preferably protrudes described groove under no external force condition, when described annular piston assembled is clutch release bearing, described anti-wear gasket makes to be between described annular piston body 1 or the described cylinder body 2 does not have friction or friction state, reduces the surface contact force between described annular piston and the described cylinder body.As known to persons of ordinary skill in the art, the contact force between the surface of contact reduces, and can reduce the frictional force between the surface of contact, further reduces wear extent, realizes better antifriction effect.
In this embodiment, described anti-wear gasket cross section is O shape.Apparently, those of ordinary skills can select different anti-wear gasket sectional shapes as required, for example square, rhombus or Hexagon etc.
In this embodiment, on the described cylinder body 2 of described clutch release bearing guard shield fixing frame 4 is housed also, be used for fixing described guard shield 3, guarantee that described clutch release bearing protects described cover 3 and plays dustproof and protective action all the time in the total travel working procedure.
In this embodiment, described clutch release bearing preferably further comprises limited ring 8, and described limited ring 8 limits the position of described annular piston assembly, prevents that described annular piston assembly from coming off from described cylinder body 2 under spring 6 effects.
In another kind of preferred implementation, as shown in Figure 5, on embodiment basis as shown in Figure 4, described cylinder body 2 is made up of described first cylinder body 11, described second cylinder body 12, described clutch release bearing also comprises, auxiliary seal ring 13 and outside framework oil seal 14.Described outside framework oil seal 14 is positioned at described clutch release bearing bottom, fits with described second cylinder body 12, plays the oil sealing effect.Described auxiliary seal ring 13 comprises two independently seal rings in this preferred implementation, between described first cylinder body 11, described second cylinder body 12 and described outside framework oil seal 14, play sealing.Described first cylinder body 11 adopts different materials to make with second cylinder body 12, and for example described first cylinder body 11 is aluminium material, and described second cylinder body 12 is the steel material.Compare embodiment as shown in Figure 4, this preferred implementation is applicable to the clutch release bearing that size is less, by the changes in material of second cylinder body 12, for described clutch release bearing provides higher intensity.
In this preferred implementation, preferably at described second cylinder body 12 limited ring 8 is housed.Described limited ring 8 limits the position of described annular piston assembly, prevents that described annular piston assembly from coming off from described second cylinder body 12 under spring 6 effects.
It is to be noted; the above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
