Abstract
The utility model discloses a piston sleeve structure of a clutch actuator, and belongs to the technical field of clutches. The structure comprises a clutch piston sleeve and a clutch casing, wherein the clutch piston sleeve is mounted to an inside base of the clutch casing; bulge structures are compressed on the outer surface of the assembled clutch piston sleeve; grooves matched with the bulge structures are formed in the inner surface of the clutch casing; and bulges on the clutch sleeve are embedded into the grooves of the clutch casing. According to the structure, the bulges on the clutch sleeve are embedded into the grooves of the clutch casing, therefore, the clutch piston sleeve is fixed at the bottom of the clutch all along in the operation and maintains normal work, and the working stability of the clutch sleeve is improved.
Description
Technical field
The utility model relates to Clutch Technology field, particularly a kind of AMT (Advanced Manufactuing Technology, advanced manufacturing technology) clutch actuator piston sleeve structure.
Background technique
The AMT control system is to add the electronic control hydraulic power drive unit of shifting and clutch on the basis of original manual transmission, thereby has kept the characteristics of mechanical gear box, have lightweight, intensity and reliability, the advantage of low energy consumption; Also can realize simultaneously automaitc shfit and clutch control function.Clutch actuator is the critical component of realizing the clutch control function.The clutch plunger sleeve is positioned at clutch actuator housing inner bottom part, is used to clutch plunger that working track is provided.Traditional clutch plunger sleeve is realized installing by directly sleeve being put into clutch actuator enclosure interior base during installation.But there are following problem in this mounting type and structure, cause clutch leakage of oil operational failure thereby the clutch plunger sleeve might cause being drawn out the mounting point because the frictional force between piston lip circle and sleeve is excessive when pistons work.Therefore, conventional mounting mode and structure can't guarantee that the clutch plunger sleeve can work under various operating modes.
The model utility content
Thereby might be drawn out the mounting point when the pistons work and cause the clutch leakage of oil and operational failure in order to solve present AMT clutch plunger sleeve, can't guarantee the problem that the clutch plunger sleeve can work under various operating modes, a kind of clutch actuator piston sleeve structure now is provided.Concrete technological scheme is as follows:
A kind of clutch actuator piston sleeve structure, comprise clutch plunger sleeve and clutch housing, described clutch plunger sleeve is installed on the internal base of described clutch housing, wherein, be pressed with protruding structure on the outer surface of the described clutch plunger sleeve that assembles, and being formed with at described clutch housing internal surface the groove that matches with described protruding structure, the projection on described clutch sleeve embeds in the groove of described clutch housing.
Preferably, described projection is the annular protrusion that is distributed on the outer surface of described clutch plunger sleeve, and described groove is the annular groove on described clutch housing.
Preferably, the composite structure of described projection and described groove is pressed with a plurality of.
Preferably, the sectional shape of described groove and described projection is V-arrangement.
Compared with prior art, the clutch actuator piston sleeve structure that technique scheme provides has the following advantages: in the groove with the protruding embeddeding clutch housing on clutch sleeve, guaranteed that clutch is fixed on clutch bottom maintenance normal operation at work all the time, has improved the working stability of clutch sleeve.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, during the below will describe embodiment, the accompanying drawing of required use is done to introduce simply, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is prior art clutch plunger bush attaching structure schematic diagram;
Fig. 2 is the clutch plunger bush attaching structure schematic diagram that provides in the utility model embodiment;
Fig. 3 is the partial enlarged drawing at A place in Fig. 2.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
The utility model embodiment provides a kind of clutch actuator piston sleeve structure, comprise clutch plunger sleeve 2 and clutch housing 1, clutch plunger sleeve 2 is installed on the internal base of clutch housing 1, tool using is pressed with protruding structure on the outer surface of the clutch plunger sleeve 2 that assembles, and be formed with at clutch housing 1 internal surface the groove that matches with protruding structure, in the groove of the protruding embeddeding clutch housing 1 on clutch sleeve 2.Wherein, projection is the annular protrusion on the outer surface that is distributed in clutch plunger sleeve 2, and groove is the annular groove on described clutch housing 1.Composite structure protruding and described groove is suppressed with a plurality of.The sectional shape of groove and projection is V-arrangement.In the groove of clutch plunger sleeve 2 by protrusion of surface embeddeding clutch housing 1, thereby be not drawn out when having guaranteed work that the mounting point causes the clutch leakage of oil and operational failure has improved the stability of clutch plunger sleeve work.
A kind of installation method of clutch actuator piston sleeve structure, the clutch actuator piston sleeve structure, comprise clutch plunger sleeve and clutch housing, the clutch plunger sleeve is installed on the internal base of described clutch housing, and wherein, the outer surface of described clutch plunger sleeve is provided with protruding structure, the clutch housing internal surface is provided with the groove that matches with described protruding structure, projection on described clutch sleeve embeds in the groove of described clutch housing, and comprises the following steps
At first the clutch plunger sleeve is installed on the internal base of described clutch housing.
Then by using special tooling that the clutch plunger sleeve surface is formed in the groove of projection and the formation of embeddeding clutch housing.
Wherein, projection is the annular protrusion on the outer surface that is distributed in the clutch plunger sleeve, and groove is the annular groove on described clutch housing.Composite structure protruding and described groove is provided with a plurality of.Further, the sectional shape of groove and described projection is V-arrangement.
The disclosed clutch actuator piston sleeve structure of the utility model embodiment has guaranteed the working stability of clutch sleeve with in clutch plunger sleeve embeddeding clutch shell, has improved economic benefit.
The above is only 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, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
