Description
Technical field
The present invention relates to a kind of fluid torque converter, can be used between motor car engine and the gearbox, is to substitute clutch to realize the self-shifting critical component, belongs to the gearbox technical field.
Background technique
But automobile torque converter is the fluid power transmission component, it can be with the variation automatic stepless speed change of external load, motor and the transmission system of can decaying effectively turn round shake and dynamic load, make the automobile that this element is housed have good startability, acceleration, stationarity and to the automatic adaptability of external load.So but can make vehicle obtain good low-speed performance the working life of significant prolongation motor and driver again, improve the passing capacity to various complex road surfaces, simplify driver's operation, minimizing is tired, improves the safety traffic ability.The automobile that has automatic transmission system need not clutch, and the driver needn't gear shift, and automaitc shfit passes to wheel by fluid torque converter with moment of torsion, so stable drive, ride comfort.
In order to improve fuel efficiency, have a lock-up clutch in the fluid torque converter, when fluid torque converter transmits energy by fluid power, high speed and part operating mode cause the loss of energy, and lock-up clutch couples together the preceding cap assembly and the turbine assembly of fluid torque converter, has prevented the fluid power energy loss, increases the locking damper mechanism simultaneously and can increase overdirve gear, in order to reducing vibrations and noise, improve fuel efficiency.
Fluid torque converter is main except that Shanghai GM at present finds by retrieval that still by import the efficient of the fluid torque converter that is used for car and light truck at the coupling point place that AIAE American institute of automobile engineers was announced in 1996 is 85%.
Summary of the invention
The purpose of this invention is to provide a kind of shock absorbing characteristics that improves under the low engine speed condition, the fluid torque converter of raising the efficiency.
For realizing above purpose, technological scheme of the present invention provides a kind of fluid torque converter, comprise a turbine and the turbine axle sleeve that is fixed on the turbine, the protecgulum that can carry out transmission of power and have convex face, between turbine and protecgulum, be provided with the locking damper mechanism of forming by helical spring, steel disc, circumferential butt and the discoid piston of axle sleeve plate, one-tenth even number, described piston can be vertically move freely towards protecgulum for putting at turbine shaft, radially to the curved surface of protecgulum direction indent; It is circumferential that described helical spring is distributed on the female parts of piston; Described axle sleeve plate is fixed on the turbine, and bore portion is close to helical spring towards the curved surface of turbine indent in it, it is characterized in that, is provided with spring sheet between circumferential butt and axle sleeve plate; Described turbine blade inlet angle is that 35 °-40 °, exit angle are 135 °-140 °, and the guide vane inlet angle is that 35 °-40 °, exit angle are 38 °-45 °, and the pump impeller blade inlet angle is that 93 °-98 °, exit angle are 105 °-108 °.
Described spring sheet is dish-shaped plate-like spring sheet.
The present invention increases dish-shaped plate-like spring sheet between circumferential butt and axle sleeve plate, increase the two-way 15.7 ± 4.9Nm of being of damping, locate for 2 ° at corner, the locking moment point that adapts to existing fluid torque converter in the world requires the trend of low speedization, improves the shock absorbing characteristics under the low engine speed condition; To adopt the variable cross section design at the guide wheel of fluid torque converter, can make fluid torque converter adapt to the motor of maximum torque point at 5200rpm, usability: efficiency eta=87%, stall torque K0=1.95-2.02, torque ratio λ=12.5, improve the bending moment performance of high engine speeds low-grade location, suitably reduce the stall converter torque ratio simultaneously, improved utilization efficiency.
Advantage of the present invention is the shock absorbing characteristics that improves under the low engine speed condition, raises the efficiency.
