The utility model discloses a double roller one way clutch structure, the design is simple, and the roller wearing and tearing are little, and bearing capacity is strong, can improve one way clutch's life -span effectively.
Description
Technical field
This utility model relates to a kind of double-row roller-type one-way clutch structure.
Background technology
The one-way clutch of fluid torque-converter includes clutch outer shroud, roller, spring and the clutch internal ring etc. being connected with guide wheel.Pump impeller couples with engine flywheel, is liquid kinetic energy by the changes mechanical energy of electromotor, the blade of hydraulic shock turbine, again liquid kinetic energy is converted into mechanical energy, by turbine output moment of torsion and rotating speed, guide wheel changes the flow direction of turbine outlet liquid, plays the effect increasing moment of torsion.Under bending moment operating mode, one-way clutch is locked, and guide wheel maintains static, and turbine output moment of torsion is more than impeller torque；Under coupling operating mode, one-way clutch is freely rotatable, and guide wheel is the most freely rotatable, and turbine output moment of torsion is equal with pump impeller.
Existing one-way clutch uses single roller, and under severe duty, the load that roller bears is big, serious wear, and one-way clutch locking state is unstable, causes turbine output moment of torsion the most unstable, has a strong impact on the service life of torque-converters.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of double-row roller-type one-way clutch structure, and this structure roller wear alleviates, bearing capacity strengthens, and is effectively improved torque-converters service life.
To achieve these goals, the technical solution adopted in the utility model is: a kind of double-row roller-type one-way clutch structure, and including guide wheel, clutch outer, clutch inner ring, roller, spring, spring base, wherein guide wheel and clutch outer couple；It is uniform-distribution with roller movement curved surface on clutch outer internal diameter, each movement curved surface has 2 through holes the most side by side；Spring moves in the through hole of clutch outer, and both ends of the spring is respectively arranged with a spring base, roller 2 the most side by side, the corresponding spring of each roller, moves between the roller movement curved surface and the outer diameter face of clutch inner ring of clutch outer.
The diameter of roller and aspect ratio are 0.63 ~ 0.67.
The internal diameter of clutch inner ring has the internal spline for connecting wheel stand.
Roller outer end also has the catch of the axially-movable limiting roller.
Catch outer end is provided with for installing bearing bearing block.
Catch and bearing block all have lubrication channel.
Guide wheel and clutch outer are coupled by steady pin.
Double-row roller-type one-way clutch structure of the present utility model, design is simple, and roller wear is little, and bearing capacity is strong, can be effectively improved the life-span of one-way clutch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 sectional view.
In figure: 1 guide wheel, 2 clutch outer, 3 catch, 4 bearing blocks, 5 clutch inner rings, 6 rollers,
7 steady pins, 8 spring bases, 9 springs.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, guide wheel 1 and clutch outer 2 are coupled by steady pin 7；It is uniform-distribution with roller movement curved surface on clutch outer 2 internal diameter, each movement curved surface has 2 through holes the most side by side；Spring 9 moves in the through hole of clutch outer 2, and spring 9 two ends are respectively arranged with a spring base 8；The diameter of roller 6 and aspect ratio are 0.65, roller 6 axially 2 side by side, and the corresponding spring 9 of each roller 6 moves between the roller movement curved surface and the outer diameter face of clutch inner ring 5 of clutch outer 2；The internal diameter of clutch inner ring 5 has internal spline, is used for connecting fixed wheel stand；Two catch 3, respectively in two row's roller 6 outer ends, limit the axially-movable of roller 6；Two bearing blocks 4 are respectively at two catch outer ends, clutch two ends, and being used for installing bearing, catch 3 and bearing block 4 all has lubrication channel, and during work, transmission oil goes to lubricate roller 6 by the oil duct of catch 3 and bearing block 4.
When, under bending moment operating mode, clutch outer 2, relative to clutch inner ring 5, rotates counterclockwise, under centrifugal action, spring 8 jack-up spring base 8 and roller 6, one-way clutch is locked, and guide wheel maintains static, and turbine output moment of torsion is more than impeller torque；When, under coupling operating mode, clutch outer 2, relative to clutch inner ring 5, turns clockwise, under centrifugal action, spring 8 is compressed, and one-way clutch is freely rotatable, and guide wheel is the most freely rotatable, and turbine output moment of torsion is equal with pump impeller.
The above is only preferred embodiments of the present utility model; it is noted that, for those skilled in the art; on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications should also be as being considered as protection of the present utility model.
