Abstract
The utility model discloses a kind of lubricated clutch that directly unloads, comprise hub axon, friction plate, and the piston of installing in hub axon, in hub axon, there is oil channel hole, friction plate external splines connects with hub axon internal spline, and described piston has oil cylinder near the end face of hub axon one side, and piston is processed with oil storage cylinder near the end face of friction plate one side, between oil storage cylinder and oil cylinder, by unloading oilhole, be communicated with, oil storage cylinder has out oil groove, and hub axon has the oil-feed tank being communicated with friction plate, oil-feed tank and go out oil groove and be communicated with.Because the utility model adopts said structure, after oil pressure disappears, hydraulic oil is through oil cylinder, the direct emptying of oil outlet and enter piston oil storage cylinder, the oil-feed tank lubricating friction plate of the fluid in oil storage cylinder in going out oil groove and hub axon.
Description
Technical field
The utility model relates to a kind of clutch, specifically a kind ofly directly unloads lubricated clutch.
Background technique
Clutch is the common components in mechanical transmission, can or engage transmission system separation at any time.General clutch emptying structure is emptying valve, as on 03 24th, 2010 disclosed application numbers Chinese utility model patent that is 200920165212.X, name is called " radial clutch emptying valve ", its principle is after oil pressure disappears, the ball of emptying valve bias under centrifugal action is exposed and is unloaded oilhole, and hydraulic oil is discharged outside clutch via aperture.
This structure exists that cost is higher, complex structure, and fluid discharges immediately clutch after completing a pressurising, and fluid utilization ratio is lower.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of lubricated clutch that directly unloads, directly emptying and have lubricating function.
To achieve these goals, the utility model is a kind of directly unloads lubricated clutch, comprise hub axon, friction plate, and the piston of installing in hub axon, in hub axon, there is oil channel hole, friction plate external splines connects with hub axon internal spline, described piston has oil cylinder near the end face of hub axon one side, piston is processed with oil storage cylinder near the end face of friction plate one side, between oil storage cylinder and oil cylinder, by unloading oilhole, is communicated with, and oil storage cylinder has out oil groove, hub axon has the oil-feed tank being communicated with friction plate, oil-feed tank and go out oil groove and be communicated with.
Because the utility model adopts said structure, after oil pressure disappears, hydraulic oil is through oil cylinder, the direct emptying of oil outlet and enter piston oil storage cylinder, the oil-feed tank lubricating friction plate of fluid in oil storage cylinder in going out oil groove and hub axon, when oil pressure rises, unload the relative oil channel hole of oilhole aperture less, do not affect oil pressure; After oil pressure disappears, hydraulic oil by unloading oilhole emptying, compares that emptying valve is simple in structure, cost is low under centrifugal action, and fluid can again utilize and is lubricated cooling to friction plate and other component.
Further, between the outer ring surface of described piston and hub axon, exterior seal ring is installed, seals, prevent the seepage of hydraulic oil.
Further, in described piston, between ring surface and hub axon, inner seal ring is installed, seals, prevent the seepage of hydraulic oil.

In figure: 1, oil-feed tank, 2, go out oil groove, 3, oil storage cylinder, 4, friction plate, 5, oil channel hole, 6, exterior seal ring, 7, unload oilhole, 8, oil cylinder, 9, hub axon, 10, piston, 11, inner seal ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model directly unloads lubricated clutch, comprise hub axon 9, friction plate 4, and the piston 10 of installing in hub axon 9, in hub axon 1, there is oil channel hole 5, friction plate 4 external spliness connect with hub axon 9 internal splines, described piston 10 has oil cylinder 8 near the end face of hub axon 9 one sides, piston 10 is processed with oil storage cylinder 3 near the end face of friction plate 4 one sides, between oil storage cylinder 3 and oil cylinder 8, by unloading oilhole 7, is communicated with, and oil storage cylinder 3 has out oil groove 2, hub axon 9 has the oil-feed tank 1 being communicated with friction plate 4, oil-feed tank 1 and go out oil groove 2 and be communicated with.
In addition, in order to prevent the seepage of hydraulic oil, between the outer ring surface of piston 10 and hub axon 9, exterior seal ring 6 is installed, between the interior ring surface of piston 10 and hub axon 1, inner seal ring 11 is installed, seal.
In concrete implementation process, hydraulic oil is along the direction as shown by arrows in FIG. of the oil channel hole 5(in hub axon 9) enter in the sealing cavity volume that piston 10 and hub axon 9 form, promote piston 10 and produce displacements, and then pressing friction sheet 4.After oil pressure disappears, hydraulic oil enters in the oil cylinder 8 of piston 10 under the effect of centrifugal force, by unloading oilhole 7, enters in oil storage cylinder 3, and the hydraulic oil in oil storage cylinder 3 is by going out oil groove 2, oil-feed tank 1 lubrication friction plate 4 and other component.When oil pressure rises, unload oilhole 7 relative oil channel hole 5 apertures less, do not affect oil pressure.After oil pressure disappears, hydraulic oil by unloading oilhole 7 emptyings, compares that emptying valve is simple in structure, cost is low under centrifugal action, and fluid can again utilize and is lubricated cooling to friction plate 4 and other component.
