The roller type one-way clutch has the characteristics of compact structure, capability of lowering the noise, prolonged service life, enhanced applicability, and the like. The roller type one-way clutch is widely applicable to the one-way clutches of the automatic transmission and automobile hydraulic torque converter, and especially can meet the requirement of transmission at 5000 rpm revolution speed and 560 NM torque.
Description
Technical field
The utility model belongs to the automatic gearbox technical field, is specifically related to the overrunning clutch structure of automatic gearbox.
Background technique
The automobile overrunning clutch as a torsion pass element in the automatic transmission, allow at a direction transmitting torque, and another direction can rotate freely.Overrunning clutch can transmit big torsion because of having, and little friction is simple in structure; Low cost of manufacture can realize torsion pass and unloaded conversion automatically according to the variation of load; Reduce vibration and noise, advantage such as be easy to control and replace traditional friction clutch and be widely used.
The structure of existing overrunning clutch as use the automobile roller-type one way clutch at present, mainly comprises outer shroud, interior ring, roller and spring.In outer shroud and the interior ring one is cam, and the structure of cam mainly contains planar section structure or eccentric arc structure or logarithm helix structure.The roller-type one way clutch action principle is: in the relative rotary course with interior ring of outer shroud, roller is pressed to outer shroud and interior ring, because the existence of cam makes the space between outer shroud and the interior ring shrink gradually, roller compresses outer shroud and interior ring until stuck motionless.Its major defect is this overrunning clutch when suffering unexpected locking, and the impulsive load that cam bears is very big, causes cam face that a lot of load impression is arranged, and the severe patient cam face peels off or crackle occurs, influences the working life of overrunning clutch.The inefficacy of roller-type one way clutch generally occurs on the cam in practical application.
Summary of the invention
The purpose of the utility model is the deficiency to existing automobile roller-type one way clutch; A kind of roller-type one way clutch is provided; Its outer shroud and interior ring are cam structure, have can the impulsive load of cam be distributed on outer shroud and the interior ring, reduce the wearing and tearing of cam; Reduce noise, improve characteristics such as working life.
The technological scheme that realizes the utility model is: a kind of roller-type one way clutch mainly comprises outer shroud, interior ring, roller, spring.It is characterized in that: described outer shroud and interior ring are cam structure.The radius R 1 of the outer surface of said outer shroud is that the radius of 40～60mm, internal surface is 29～41mm; The thickness of said outer shroud is 9.2～11mm; At the internal surface place of said outer shroud 6～9 eccentric arcs that concave are set evenly; The radius R 2 of each eccentric arc is 28～45mm, and the eccentric distance e between the center of circle O1 of the center of circle O2 of each eccentric arc and the outer surface of said outer shroud is 3.2～6.8mm.The radius R 3 of the outer surface of ring matees with the radius of the internal surface of said outer shroud in said; The center of circle of the outer surface of the center of circle of the outer surface of ring and said outer shroud is same center of circle O1 in said; The thickness of the thickness of ring and said outer shroud coupling in said; In said, on the outer surface of ring and corresponding to the middle section of the eccentric arc of the internal surface of said outer shroud 6～9 planar sections are set evenly, the length t of each planar section is 8.2～10.7mm.When described outer shroud and described in after the ring assembling, width of planar section formation of the eccentric arc of the internal surface of each outer shroud and the outer surface of corresponding interior ring is by the wide space that narrows down gradually (being the roller space), totally 6～9 roller spaces.Described roller is 6～9; The radius R 4 of each roller is 4.2～6.9mm; The length of said roller and the thickness of said outer shroud coupling; 6～9 rollers are placed on respectively in described 6～9 roller spaces, the tangent line of each roller and the eccentric arc intersection point of the internal surface of said outer shroud and this roller with corresponding in the angle of tangent line of planar section intersection point of outer surface of ring be 7.13 °～8.22 °.Described spring is 6～9, and every spring is placed in the described roller space, and an end of every spring withstands on respectively on each roller, and the other end of every spring withstands on respectively on the wide side in each roller space.When outer shroud rotates; Under the outer shroud turning effort; The every equal pressurized of spring and shrinking, each roller respectively under the effect of the compression elasticity of every spring respectively to the narrow side roll in described roller space, till motionless by roller space chucking; Play the transmission twisting force, accomplish the function of transmitting torsion.
The utility model mainly contains following effect after adopting technique scheme:
1, outer shroud and interior ring all adopt cam structure; Impulsive load to cam in the time of can be with the roller locking is dispersed on outer shroud and the interior ring; Effectively reduce the load and the pressure of single cam, reduced contact fatigue strength, significantly improved the wearing and tearing of outer shroud and interior ring; Thereby improved working life, and weakened the noise of overrunning clutch transmission.
2, adopt 7.13 °～8.22 ° angle, Rapid Realization latch functions not only, and the locking scope is increased, strengthened the applicability of this roller-type one way clutch.
3, the utility model compact structure can satisfy the requirement of Hyundai Motor spatial limitation.
4, the utility model can satisfy the transmission demand of rotating speed 5000rpm, moment of torsion 560NM.
The utility model can be widely used as the overrunning clutch of automatic gearbox, also can be used as the overrunning clutch of fluid torque converter.
