In recent years, economy is proposed to be strict with by auto industry, thus occurs in that closed-end hydraulic torque converter.Adding a lockup clutch between pump impeller and turbine, when vehicle starting, acceleration, gearshift and difficulty road traveling need application fluid torque-converter performance, lockup clutch unclamps；When automobile is when better road surface smooth-ride, lockup clutch combines, and pump impeller and turbine entirety are turned round, and guide wheel dallies, and becomes machine driving, thus efficiency is close to 1.Adopting closed-end hydraulic torque converter according to statistics, vehicle fuel consumption can reduce by 10～15%.
In vehicle use procedure, converter lockout, unlock very frequent.Therefore, the effect of the lockup clutch economy to automobile, comfortableness impact is very big.
Utility model content
This utility model purpose is to provide a kind of fluid torque-converter wet type lockup clutch, it adopts wet type lockup clutch, have contact steadily, transmission moment of torsion is big, the low pressure height swift feature of rotating speed locking, it is adaptable to the closed-end hydraulic torque converter of coupling 120N.m～180N.m electromotor.
Technical solution of the present utility model is:
A kind of fluid torque-converter wet type lockup clutch, it is characterized in that, including housing, follower plate, retainer, paper-base friction wafer；Described follower plate and retainer pass through rivet interlacement；Described torsion vibration absorber adopts two groups of springs of size, and big group spring includes 8 big springs of arranged tangential and circumference uniform distribution, and group's spring includes 4 little springs of arranged tangential and circumference uniform distribution；Described little spring is arranged in big spring；Described retainer forms spring installing space, adjusts big spring precommpression by spring pad；Described annular paper-base friction wafer is bonded on follower plate and forms friction pair with housing.
Preferably scheme, being bonded in the angle between the 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 utility model:
1, when automobile torque converter requires clutch separation, it is completely separated, soft during joint, and there is good heat-sinking capability.The friction plate of lockup clutch of the present invention is paper-base friction wafer, bonding cementing with follower plate, mating material is mild steel, uses paper-base friction wafer, and the coefficient of friction change of platen pressure and friction plate is little, working stability, in conjunction with steadily, coefficient of friction is high, and kinematics and static friction factor is close, reversing impact is little, and heat-sinking capability is strong.
2, lockup clutch requires to guarantee the torque capacity that transmission electromotor sends, and also has certain transmission torque surplus energy.The piston plate pressurization area of lockup clutch of the present invention is big, and external diameter is 215.9mm, and the little 39.5mm of hole size, in low voltage difference situation, such as 0.4MPa, it is possible to realize 130N.m outfan, input clutch, big in conjunction with moment of torsion, adapts to wide.
3, this utility model lockup clutch, piston plate and dual face adopt opposed facets, and 0.35 ° at an angle, piston plate moulding surface structure is compact, and rigidity is big.At electromotor height rotating speed, the good stability that during applying working condition high temperature 115 °, torque-converters combines, impacting little, clutch response speed is fast.
4, this utility model lockup clutch adopts two groups of springs tangentially assembled, and carries out vibration damping；There is mitigation rotation direction impact, the ability of decay direction vibration, and noise is little.These two groups of springs include 8 groups of big springs and 4 groups of little springs, equal tangential distribution, spring endurance 10,000,000 times, and secondary torsional vibration reduction stroke reaches 11.7 °, and moment of torsion is 195N.m, reverse damping effect notable.
5, the rotary inertia of this utility model secondary part is as far as possible little, when separating clutch shift, being just easier change with the rotating speed of transmission input shaft connected component, impacting thus alleviating between gear.
