Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to further concrete detailed explanation.
As shown in the figure, a kind of wet clutch, comprise main shaft 1, hub 15 in the outer hub 2 of clutch plunger cylinder 3, clutch and clutch, is fixedly connected with between clutch plunger cylinder 3 and main shaft 1, for the reliability that guarantees to connect, increase transmitting torque, and simplified design and processing technology, reduce fabricating cost and simplify and install and assembly technology, the present embodiment adopts tapering interference fit to connect, and tapering can adopt wherein any of 1:10 ~ 1:50.
The outer hub 2 of clutch is fixedly connected with clutch plunger cylinder 3, and the present embodiment clutch adopts laser bonding mode to be fixedly connected with between hub 2 and clutch plunger cylinder 3 outward.Adopt laser bonding mode the amount of deformation of clutch hub can be dropped to minimum, when guaranteeing join strength, improve production efficiency and product quality.
In clutch, hub 15 is arranged on the inside of the outer hub 2 of clutch, adopts spline to be provided with a plurality of friction plates 5 outside clutch on the inner circumference of hub 2, and the present embodiment friction plate adopts paper-base friction wafer; The pressure angle of spline can adopt an angle in 10 ° ~ 18 °, and the pressure angle that the present embodiment adopts is 15 °; In clutch, on the excircle of hub 15, adopt spline to be provided with a plurality of antithesis sheets 6, the pressure angle of spline can adopt an angle in 10 ° ~ 18 °, and the pressure angle that the present embodiment adopts is 15 °.A plurality of friction plates 5 and a plurality of antithesis sheet 6 are crisscross arranged.A slice near clutch plunger cylinder 3 bottoms is friction plate.Adopt 10 ° ~ 18 ° such pressure angles can make the tooth depth of spline lengthen, thereby guarantee endwisely slipping steadily of friction plate and antithesis sheet, increase the moment of torsion transmitting simultaneously.
Hub 15 and outside clutch between hub 2 in clutch, and be provided with platen 13 in the end away from clutch plunger 4, a plurality of friction plates 5 and a plurality of antithesis sheet 6 are carried out to location, axial one end, in the outside of platen 13, the outer hub 2 of clutch is provided with the clutch snap ring 14 for platen 13 is positioned.
In clutch plunger cylinder 3, be provided with clutch plunger 4, clutch plunger 4 is located at clutch plunger cylinder 3 near bottom one side, in clutch, hub 15 is provided with a butterfly steel disc 7 near one end of clutch plunger 4, on main shaft 1, clutch plunger 4 is fixedly connected with spring 8 near a side of dish-shaped steel disc 7, the other end of spring 8 is provided with check ring 9, and check ring 9 relies on the axle being located on main shaft 1 to carry out axial restraint with snap ring 10.
Clutch plunger 4 adopts aluminum alloy to process and be made through anode oxidation process.Adopt aluminum alloy to make the weight that piston can alleviate clutch plunger, reduce the rotary inertia in transmittance process, improve the stationarity of transmitting; Adopt anodizing, can strengthen wear resistance and the rigidity of clutch plunger.
On main shaft 1, be provided with towards the oil duct of clutch plunger cylinder 3, the opening K of oil duct is arranged on one end of main shaft 1, in the bottom of clutch plunger cylinder 3 and the bottom of clutch plunger 4 be equipped with the aperture B for buffer clutch piston cylinder 3 internal oil pressure, the aperture B that the present embodiment arranges in clutch plunger cylinder 3 bottoms is 1, size preferably diameter is 0.5-3mm, this aperture of the present embodiment B diameter is 2mm, the aperture D arranging in the bottom of clutch plunger 4 is two, its medial axis symmetry with respect to clutch plunger 4 is established, put, size preferably diameter is 1.5.-9mm, this aperture of the present embodiment D diameter is 6mm.
On the excircle of clutch plunger 4 He on inner circumference, be equipped with oil ring groove, rectangular loop 12 is installed in the oil ring groove of excircle, the sectional shape of rectangular loop 12 is rectangle, it can improve the sealing area on sealing surface and clutch plunger cylinder 3 surfaces, it is darker that rectangular loop 12 is installed to the interior degree of depth of groove simultaneously, can prevent that seal ring from being extruded by oil pressure, thereby guarantee the reliability of sealing, the working life of improving clutch.O shape circle 11 is installed in the oil ring groove of inner circumference.
During use, in clutch, hub 15 can be connected with a driving component, described driving component can be gear or be with cogged transmission shaft, by the transmission and the partition that move between the combination between friction plate 5 and antithesis sheet 6 and the separated motion that realizes main shaft 1 and driving component.
During work, clutch oil enters from filler opening K, by the oil duct of main shaft 1 inside, enter in the cavity forming between clutch plunger cylinder 3 and clutch plunger 4, clutch oil is pushed clutch plunger 4 to butterfly steel disc 7 rapidly, and butterfly steel disc 7 is out of shape draining aperture D closed under the effect of thrust, under the promotion of clutch plunger 4, friction plate 5 and antithesis sheet 6 endwisely slip along spline separately, finally, together with a plurality of friction plates 5 are pulled to the other end and are pressed also with a plurality of antithesis sheets 6, clutch is just realized the function of combination, thereby the rotation of main shaft 1 is passed to the outer hub 2 of clutch by clutch plunger cylinder 3, the outer hub 2 of clutch by transmission of power to friction plate 5, because now friction plate 5 and antithesis sheet 6 be press and together with, so friction plate 5 just passes to hub 15 in clutch by power by antithesis sheet 6, thereby in clutch, hub 15 can be given coupled driving component by transmission of power.
In clutch cohesive process, clutch oil constantly enters in the cavity of clutch plunger 4 and 3 formation of clutch plunger cylinder from oilhole K, owing to being provided with draining aperture B in clutch plunger cylinder 3 bottoms, so clutch oil is in entering the process of clutch plunger cylinder 3 cavitys, also have one through draining aperture B, outwards to release on a small quantity that (oil gushing can directly pass into the fuel tank that clutch oil is provided for hydraulic system, not shown) process, thereby play the effect of constantly stablizing clutch plunger cylinder 3 internal oil pressure, and guarantee that clutch oil is in dynamic process simultaneously, thereby guarantee that oil temperature can not raise, finally improved the stability of clutch combination, reduce gearshift shock and vibration, and the life-span of having improved clutch.
When clutch need to disconnect, filler opening K place oil pressure disconnects, clutch plunger 4 is return under the effect of spring 8, promote clutch plunger 4 oil in clutch cavity is turned back to fuel tank by the oil duct in main shaft 1 from oilhole K, and can release a part through draining aperture B simultaneously, in addition, in the process of spring 8 returns, butterfly steel disc 7 restores, two draining aperture D of clutch plunger 4 open rapidly, make the clutch oil in clutch plunger cylinder 3 cavitys can enter clutch plunger 4 near a side of butterfly steel disc 7 simultaneously, further from being located at clutch, the oil drainage hole on hub 2 (not marking in figure) releases fast, reach the object of the quick Quick release of clutch.
