Abstract
The invention discloses a clutch actuator piston sleeve and an installation method and belongs to the technical field of clutches. The clutch actuator piston sleeve comprises a clutch piston sleeve and a clutch casing; the clutch piston sleeve is installed on an interior base of the clutch casing; an embossment structure is pressed on an outer surface of the assembled clutch piston sleeve; a groove which is matched with the embossment structure is formed in an inner surface of the clutch casing; an embossment on the clutch sleeve is embedded into the groove of the clutch casing. The clutch actuator piston sleeve and the installation method guarantee that the clutch is fixed at the bottom of the clutch to keep normal operation and improve the working stability of the clutch sleeve due to the fact that the embossment on the clutch sleeve is embedded into the groove of the clutch casing.
Description
Technical field
The present invention relates to Clutch Technology field, particularly a kind of AMT (Advanced Manufactuing Technology, advanced manufacturing technology) clutch actuator piston sleeve structure and installation method.
Background technique
AMT control system is on the basis of original manual transmission, to add the electronic control hydraulic power drive unit of shifting and clutch, thereby has retained the feature of mechanical gear box, have lightweight, intensity and reliability, the advantage of low energy consumption; Also can realize automaitc shfit and clutch control function simultaneously.Clutch actuator is the critical component of realizing clutch control function.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, realizes installation by directly sleeve being put into clutch actuator enclosure interior base when installation.But this mounting type and structure, exist following problem, cause being drawn out mounting point and cause clutch leakage of oil operational failure thereby clutch plunger sleeve is likely can be because of the frictional force between piston lip circle and sleeve in the time of pistons work excessive.Therefore, conventional mounting mode and structure cannot ensure that clutch plunger sleeve can normally work under various operating modes.
Summary of the invention
Thereby likely can be drawn out mounting point when the pistons work and cause clutch leakage of oil and operational failure in order to solve current AMT clutch plunger sleeve, cannot ensure the problem that clutch plunger sleeve can normally be worked under various operating modes, a kind of clutch actuator piston sleeve structure and installation method are now 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, on the outer surface of the described clutch plunger sleeve assembling, be pressed with protruding structure, and being formed with at described clutch housing internal surface the groove matching 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 being 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 multiple.
Preferably, the sectional shape of described groove and described projection is V-arrangement.
A kind of installation method of clutch actuator piston sleeve structure, described 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, the outer surface of described clutch plunger sleeve is provided with protruding structure, and described clutch housing internal surface is provided with the groove matching with described protruding structure, and the projection on described clutch sleeve embeds in the groove of described clutch housing; And comprise the following steps,
Described clutch plunger sleeve is installed on to the internal base of described clutch housing;
By using special tooling that clutch plunger sleeve surface is formed in the groove of projection the formation of embeddeding clutch housing.
Further, described projection is the annular protrusion being distributed on the outer surface of described clutch plunger sleeve, and described groove is the annular groove on described clutch housing.
Further, the composite structure of described projection and described groove is provided with multiple.
Further, the sectional shape of described groove and described projection is V-arrangement.
Compared with prior art, clutch actuator piston sleeve structure and installation method that technique scheme provides have the following advantages: by by the groove of the protruding embeddeding clutch housing on clutch sleeve, ensure that clutch is fixed on all the time at work clutch bottom and keeps normal work, improved the working stability of clutch sleeve.
Brief description of the drawings
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of 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 providing in the embodiment of the present invention;
Fig. 3 is the partial enlarged drawing at A place in Fig. 2.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
The embodiment of the present invention 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, on the outer surface of the clutch plunger sleeve 2 assembling, use instrument is pressed with protruding structure, and be formed with at clutch housing 1 internal surface the groove matching with protruding structure, in the groove of the protruding embeddeding clutch housing 1 on clutch sleeve 2.Wherein, projection is for being distributed in the annular protrusion on the outer surface of clutch plunger sleeve 2, and groove is the annular groove on described clutch housing 1.Composite structure protruding and described groove is suppressed with multiple.Groove and protruding sectional shape are V-arrangement.In the groove of clutch plunger sleeve 2 by protrusion of surface embeddeding clutch housing 1, thereby while having ensured work, be not drawn out that mounting point causes 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, clutch actuator piston sleeve structure, comprise clutch plunger sleeve and clutch housing, 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, clutch housing internal surface is provided with the groove matching with described protruding structure, projection on described clutch sleeve embeds in the groove of described clutch housing, and comprises the following steps
First clutch plunger sleeve is installed on to the internal base of described clutch housing.
Then by using special tooling that clutch plunger sleeve surface is formed in the groove of projection the formation of embeddeding clutch housing.
Wherein, projection is for being distributed in the annular protrusion on the outer surface of clutch plunger sleeve, and groove is the annular groove on described clutch housing.Composite structure protruding and described groove is provided with multiple.Further, the sectional shape of groove and described projection is V-arrangement.
The disclosed clutch actuator piston sleeve structure of the embodiment of the present invention and installation method, by clutch plunger sleeve embeddeding clutch shell, have ensured the working stability of clutch sleeve, have improved economic benefit.
