Description
Technical field
The present invention relates to the lockup clutch of automobile torque converter.
Background technique
For three active wheels simple centripetal turbine formula fluid torque converter, its higher efficiency range is very narrow, very low in the efficiency of low speed and high velocity, and automobile, engineering vehicle operating range requires very wide, can not ensure to work in fluid torque converter higher efficiency range, reduce transmission average efficiency, be degrading Economy, and bring higher cooling requirements.
For expanding torque-converters higher efficiency range, occurred that guide wheel can wedging and the converter coupling unclamped automatically, when speed ratio height, guide wheel idle running, improve the efficiency in high rotating ratio district, its average transmission is only about 80 ~ 85%.
In recent years, automotive industry proposes to be strict with to Economy, has thus occurred closed-end hydraulic torque converter.Between pump impeller and turbine, add a lockup clutch, when vehicle starting, acceleration, gearshift and difficult road traveling need application fluid torque converter performance, lockup clutch unclamps; When automobile is in better road surface smooth-ride, lockup clutch combines, and pump impeller and the revolution of turbine entirety, guide wheel dallies, and become mechanical transmission, thus efficiency is close to 1.Adopt closed-end hydraulic torque converter according to statistics, vehicle fuel consumption can reduce by 10 ~ 15%.
In vehicle using process, converter lockout, unlock very frequent.Therefore, the effect of lockup clutch is to the Economy of automobile, and travelling comfort impact is very large.
Summary of the invention
The object of the invention is to provide a kind of fluid torque converter wet type lockup clutch, it adopts wet type lockup clutch, have contact steadily, large, the swift feature of low pressure height rotating speed locking of transmitting torque, be applicable to the closed-end hydraulic torque converter mating 120N.m ~ 180N.m motor.
Technical solution of the present invention is:
A kind of fluid torque converter wet type lockup clutch, its special way is, comprises housing, follower plate, retainer, paper-base friction wafer; Described follower plate and retainer pass through rivet interlacement; Described torsion vibration absorber adopts size two groups of springs, and large group spring comprises arranged tangential and 8 of circumference uniform distribution big springs, and group's spring comprises arranged tangential and 4 of circumference uniform distribution little springs; Described little spring is arranged in big spring; Described retainer forms spring fitting space, by the precompression of spring pad adjustment big spring; Described ring paper-base friction wafer to be bonded on follower plate and to form friction pair with housing.
Preferably scheme, the angle be bonded between friction plate on follower plate and housing is 0.35 degree.
Above-mentioned follower plate is sheet metal structural.
Above-mentioned housing is low-carbon steel material.
The external diameter of above-mentioned follower plate is 215.9mm, and endoporus is 39.5mm.
Advantage of the present invention:
1, during automobile torque converter requirement clutch separation, be thoroughly separated, soft during joint, and there is good heat dissipation potential.The friction plate of lockup clutch of the present invention is paper-base friction wafer, bonding cementing with follower plate, mating material is low carbon steel, uses paper-base friction wafer, and the friction factor change of platen pressure and friction plate is little, working stability, in conjunction with steady, friction factor is high, and kinematics and static friction factor is close, reversing impact is little, and heat dissipation potential is strong.
2, lockup clutch requirement guarantees the peak torque that transmission motor sends, and also has certain transmitting torque surplus energy.The piston plate pressurization area of lockup clutch of the present invention is large, and external diameter is 215.9mm, the little 39.5mm of hole size, in low voltage difference situation, as 0.4MPa, also can realize 130N.m output terminal, input end clutch, large in conjunction with moment of torsion, adapts to wide.
3, lockup clutch of the present invention, piston plate and dual face adopt opposed facets, and 0.35 ° at an angle, piston plate moulding surface structure is compact, and rigidity is large.At motor height rotating speed, the good stability that during applying working condition high temperature 115 °, torque-converters combines, impact little, clutch reaction velocity is fast.
4, lockup clutch of the present invention adopts two groups of springs tangentially assembled, and carries out vibration damping; Have and relax sense of rotation impact, the ability of this direction vibration that decays, and noise is little.These two groups of springs comprise 8 groups of big springs and 4 groups of little springs, equal tangential distribution, spring endurance 1,000 ten thousand times, and secondary torsional vibration reduction stroke reaches 11.7 °, and moment of torsion is 195N.m, reverse damping effect remarkable.
5, the rotary inertia of secondary part of the present invention is as far as possible little, when cut-off clutch gear shift, just changes than being easier to the rotating speed of transmission input shaft connected component, thus alleviates between gear and impact.
