Abstract
The utility model provides a gear hub, a hydraulic automatic gearbox and an automobile. The gear hub is provided with a non-working plane. An oil hole is formed in the gear hub, and the side wall of one side of the oil hole is intersected with a projection line of the non-working plane in the direction of the cross section. According to the gear hub provided by the technical scheme, the side wall of one side of the oil hole is intersected with the projection line of the non-working plane, the resistance subjected by lubricating oil in the process of discharging can be reduced, and the lubricating effect is guaranteed.
Description
Technical field
The utility model relates to mechanical technique, relates in particular to a kind of tooth hub, hydraulic automatic speed variator and automobile.
Background technique
The tooth hub of clutch is one of core component of hydraulic automatic gearbox.Automatic transmission case control unit (TCU, Transmission Control Unit) by solenoidoperated cluthes oil hydraulic cylinder back and forth movement, changing friction plate is combined with the compression of steel disc or separates and realize that the motion of tooth hub, static state switch, and make power transmit along different paths.The tooth hub, as the powerdriven bridge of gearbox, will directly cause the kinetic current medium in case lose efficacy, and the reliable running of its temperature is most important.
Fig. 1 a is the structural representation of tooth hub in prior art, and Fig. 1 b is the local enlarged diagram of Fig. 1 a.Referring to Fig. 1 a and Fig. 1 b, tooth hub 1 has working surface and non-working surface.On tooth hub 1, also be provided with the oilhole 2 of lubricated use, on cross-sectional direction, the both sides of oilhole 2 are symplex structure, and between the projection line 3 of the non-working surface of the dual-side of oilhole 2 and tooth hub 1, have certain for a.
There is following problem at least in prior art: existing tooth hub oilhole is symplex structure, and rotation utilizes centrifugal force that lubricant oil is thrown away by oilhole to lubricant oil by the tooth hub, the lubrication friction parts.Due to effect of inertia, lubricant oil will flow out through oilhole along tooth hub profile of tooth inwall, and symmetry properties tooth hub has inhibition to lubricant oil, and lubricant oil can not be flowed out smoothly fully, and then affects the lubrication effect of friction means.
The model utility content
The utility model provides a kind of tooth hub, hydraulic automatic speed variator and automobile, be used to optimizing the structure of existing tooth hub.
The utility model provides a kind of tooth hub, has non-working surface, on described tooth hub, offers oilhole, and wherein: on cross-sectional direction, the sidewall of described oilhole one side and the projection line of described non-working surface intersect.
Tooth hub as above, preferably,
Described oilhole is square hole.
The utility model also provides a kind of hydraulic automatic speed variator, wherein, comprises the tooth hub that the utility model provides arbitrarily.
The utility model provides again a kind of automobile, it is characterized in that, comprises hydraulic automatic speed variator provided by the utility model.
After the sidewall of oilhole one side and the non-working surface of tooth hub intersected, lubricant oil when oilhole, flowing out, not there will be the phenomenons such as accumulation, cohesion, and namely under the effect of centrifugal force, lubricant oil can be discharged smoothly.
The accompanying drawing explanation
Fig. 1 a is the structural representation of tooth hub in prior art;
Fig. 1 b is the local enlarged diagram of Fig. 1 a;
The tooth hub structure schematic diagram that Fig. 2 a provides for the utility model embodiment;
Fig. 2 b is the local enlarged diagram of Fig. 2 a;
Fig. 2 c is the scheme of installation of tooth hub shown in Fig. 2 a.
Embodiment
The tooth hub structure schematic diagram that Fig. 2 a provides for the utility model embodiment, Fig. 2 b are the local enlarged diagram of Fig. 2 a, and Fig. 2 c is the scheme of installation of tooth hub shown in Fig. 2 a.
The utility model embodiment provides a kind of tooth hub 4, especially refer to clutch tooth hub, tooth hub 4 has non-working surface, on described tooth hub 4, offers oilhole 5, wherein: on cross-sectional direction, the sidewall 6 of described oilhole 5 one sides intersects with the projection line of described non-working surface 7.
The tooth hub 4 of clutch in the hydraulic automatic gearbox as the supporting mechanism of the friction means 8 such as clutch plate and antithesis sheet, for the slip of friction means 8 guiding is provided and by transmission of power to film material parts.
After the sidewall of oilhole one side and the non-working surface of tooth hub intersected, lubricant oil when oilhole, flowing out, not there will be the phenomenons such as accumulation, cohesion, and namely under the effect of centrifugal force, lubricant oil can be discharged smoothly.
For ease of manufacturing, described oilhole is square hole.With circular hole, compare, square hole flows more favourable to oil product, makes fluid more easily flow.
The tooth hub that technique scheme provides, the sidewall of a side of its oilhole and the non-working surface of described tooth hub intersect, and can reduce the resistance that is subject in the lubricant oil discharge process, guarantee lubrication effect.
The utility model embodiment also provides a kind of hydraulic automatic speed variator, wherein, comprises the tooth hub that the utility model any embodiment provides.
The hydraulic automatic speed variator that technique scheme provides, have above-mentioned tooth hub, and the sidewall of a side of its oilhole and the non-working surface of described tooth hub intersect, and can reduce the resistance that is subject in the lubricant oil discharge process, guarantees lubrication effect.
The utility model embodiment provides a kind of automobile again, wherein, comprises the hydraulic automatic speed variator that the utility model any embodiment provides.
The hydraulic automatic speed variator that technique scheme provides, have above-mentioned hydraulic automatic speed variator, and the sidewall of a side of its tooth hub upper oil hole and the non-working surface of described tooth hub intersect, and can reduce the resistance that is subject in the lubricant oil discharge process, guarantees lubrication effect.
Finally it should be noted that: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to aforementioned each embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, or some or all of technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment's technological scheme of the utility model.
