Abstract
The utility model relates to an interlock speed regulating hydraulic clutch, which belongs to a hydraulic clutch. The transmitted power of the utility model is the engagement of liquid motive power and friction plates. The utility model is composed of an existing hydraulic clutch and a mechanical multi-plate friction clutch. The utility model is characterized in that friction plates are arranged on a driven shaft and a rotating casing, and an oil cylinder and a piston is additionally connected with a turbine. The no slip running can be realized in a rated condition, and the transmission efficiency of the utility model can be enhanced about 3%.
Description
The utility model relates to a kind of locking speed governing hydraulic coupler, and it belongs to fluid clutch, and its transmitted power is by the joint of hydrodynamic and friction plate (F16D35/00).
Existing variable speed fluid coupling has flexible transmission, stepless speed regulation, isolation and absorbs a series of advantages such as vibration, overload protection and starting under no load motor; but by the caused hydraulic-slip loss of the characteristic of hydraudynamic drive; make this device under declared working condition; always exist about about 3% slip power loss, make its blemish in an otherwise perfect thing.
In order to make up a deficiency again with its advantage, the utility model proposes a kind of novel transmission component for this reason, its multi-plate friction clutch of combination in existing variable speed fluid coupling constitutes, and it has the function of variable speed fluid coupling and multi-plate friction clutch simultaneously.In rotating ratio i=0-0.97 scope, be, when rotating ratio reaches the operating mode of i=0.97, can make the oil-filled joint of clutch oil cylinder, make rotating ratio i=1 by variable speed fluid coupling work.Under declared working condition, just realize no slippage running like this, thereby improved transmission efficiency about 3%.
The utility model is a kind of locking speed governing hydraulic coupler, it is that import, outlet regulating formula is various, and variable speed fluid coupling and mechanical type multi-disc friction slice clutch combine, under declared working condition, can realize not having the slippage running, thereby avoid the hydraulic-slip loss under declared working condition.This coupler is by outer cover, driving shaft, the pump impeller and rotation case, driven shaft, the turbine that links to each other with driven shaft and the working oil that link to each other with driving shaft, mobile honeycomb duct is formed, wherein pump impeller and turbine adapting device, on the corresponding with it rotation case inner circumference one group of driving and driven friction plate is being housed respectively on the excircle of the driven shaft at turbine back, both are alternately and arrange; Be provided with an oil cylinder from the turbine back side in movable friction plate the place ahead, piston wherein can with contact from movable friction plate, be equipped with bearing disc and shelves ring from the driven shaft at movable friction plate rear, the bearing disc one side leans against on the shelves ring mutually, another side can contact with active friction plate, be provided with Returnning spring between bearing disc and the oil cylinder piston, after this Returnning spring passed perforation from the movable friction plate, its two ends were attached to respectively on piston and the bearing disc.
When active part is rotated by the motor constant-speed drive, at first charge into working oil to the coupler rotor chamber, this moment, coupler just carried out work with outlet regulating formula speed governing hydraulic coupler, working oil after working in the coupler rotor chamber just enters auxiliary oil pocket, and, sent back to fuel tank from the working oil that mobile honeycomb duct is derived through mobile honeycomb duct derivation.Just can realize the step-less adjustment of output shaft rotating speed by mobile honeycomb duct.
Speed governing hydraulic coupler general rotating ratio under the rated load operating mode can only reach 0.97, when the oil cylinder of lockup clutch charges into Clutch Control oil, the piston of clutch just moves right under the promotion of hydraulic oil, promote active friction plate and from movable friction plate, on spline separately, move and compress, realize the combination of clutch, the power of driving shaft input does not have the output shaft that spreads out of of hydraulic-slip loss through this lockup clutch like this, thereby makes transmission efficiency improve about 3%.
The utility model advantage compared with the prior art is: it has overcome the loss of existing fluid coupling slippage, thereby makes transmission efficiency improve about 3%.
The utility model can also be further specified from the following drawings and embodiment.
Figure, the vertical cross-sectional schematic of the utility model.
Drawing numbering: 1-driving shaft, 2-pump impeller, 3-turbine, the 4-rotation case, 5-oil cylinder, 6-piston, 7-active friction plate, 8-are from movable friction plate, and 9-assists oil pocket, 10,15-working oil, 11-bearing disc, 12-are controlled oil, 13-shelves ring, the 14-driven shaft, 16-moves honeycomb duct, the 17-Returnning spring, 18-coupler rotor chamber, 19-outer cover.
Below in conjunction with accompanying drawing, the utility model is described in detail.
The utility model is contained on the bearing of outer cover 19 by driving shaft 1, it links to each other with pump impeller 2, rotation case 4 usefulness screws, on rotation case 4 inner circumferences through spline link to each other with active friction plate 7 (or active friction plate 7 is screwed on rotation case 4 inner circumferences), it can slide on spline, and above element has constituted the active part of driving component; Turbine 3, oil cylinder 5 is that an integral body (perhaps is single part with driven shaft 14, be assembled into integral body with screw), piston 6 is contained in the oil cylinder 5, be sleeved on from movable friction plate 8 and (also can be contained on the slip ring on the spline of driven shaft 14 cylindricals from movable friction plate 8, and slip ring is nested with on driven shaft 14), main, from movable friction plate 7,8 dress methods are: adorn one from movable friction plate 8 at the spline upper sleeve of driven shaft 14 earlier, then adorning an active friction plate 7(active friction plate 7 at the spline upper sleeve of rotation case 4 inner circumferences also can be screwed in rotation case 4 on the circle), again by said procedure load onto successively from, active friction plate 7,8, Returnning spring 17 passes from the perforation of movable friction plate 8 near spline, the one end is attached on the piston, refill bearing disc 11, bearing disc 11 1 ends lean on mutually with the other end of Returnning spring 17, at last shelves ring 13 is sleeved on the driven shaft 14, and leans on mutually with bearing disc 11; Bearing disc 11 is by being fixed as an integral body from movable friction plate and steel disk.The turbine end of driven shaft 14 is inserted in the stomidium of driving shaft 1, and the other end is contained on the bearing of outer cover 19, thereby, constituted the secondary part of transmission by above-mentioned all elements.The friction plate of this coupler is made copper-base powder metallurgy with steel.
