Definitions

  • the invention relates generally to torque converters, and more particularly to the mounting of a spring retainer for a torque converter using tongues and a method of making the spring retainer fastener.
  • This present invention generally relates to a fastener using the tab of a turbine blade for a damper spring retainer of a torque converter and a method of manufacturing the fastener. It is known in the art that torque converters are equipped with damping springs and fasteners.
  • FIG. 1 illustrates a general block diagram showing the relationship between the engine 7, the torque converter 10, the transmission 8, and a differential / axle assembly 9 in a typical vehicle.
  • FIGS 2 to 6 show that the pump 37, the turbine 38 and the stator 39 are the main components of the torque converter.
  • the torque converter becomes a sealed chamber.
  • the lid is connected to a wobble plate (flexplate) 41, which in turn is bolted to the crankshaft 42 of the motor 7.
  • the lid may be connected to the wobble plate using ridges or pins which are welded to the lid.
  • the welded connection between the pump and the cover transmits a torque of the motor to the pump. Therefore, the pump always rotates at the engine speed.
  • the job of the pump is to use This rotational movement to convey the liquid in the radial direction outwards and in the axial direction to the turbine.
  • the pump serves as a centrifugal pump, which conveys the liquid from a small radial inlet to a large radial outlet, thus increasing the energy in the liquid.
  • the pressure for engaging the transmission clutches and the torque converter clutch is provided by an additional pump in the transmission, which is driven by the pump hub.
  • a fluid circuit is established by the pump (sometimes referred to as an impeller), the turbine, and the stator (sometimes referred to as a reactor).
  • the fluid circulation allows the engine to continue running when the vehicle is stopped and to accelerate the vehicle again when desired by a vehicle operator. Similar to a gear reduction, the torque converter increases the torque of the engine through a torque ratio.
  • the torque ratio is equal to the ratio of output torque to input torque.
  • the torque ratio is highest at low speed or zero turbine speed (also referred to as stalling).
  • the torque ratios when stalling the engine are usually in the range of 1.8 to 2.2. This means that the output torque of the torque converter 1, 8 to 2.2 times as large as the input torque.
  • the output speed is much lower than the input speed because the turbine is connected to the output and does not rotate while the input is rotating at the speed of the motor.
  • the turbine 38 uses the liquid energy received by the pump 37 to drive the vehicle.
  • the housing shell 22 of the turbine is connected to the turbine hub 19.
  • the turbine hub 19 uses a keyway connection to transmit the torque of the turbine to the drive shaft 43 of the transmission.
  • the drive shaft is connected via gears and shafts in the transmission 8 and an axle differential 9 with the wheels of the vehicle.
  • the force of the liquid impinging on the turbine blades is output by the turbine in the form of a torque.
  • Axial thrust bearings 31 restrain axial forces exerted by the fluid from the components. If the output torque is sufficient to overcome the inertia of the stationary vehicle, the vehicle starts moving. After the liquid energy has been converted by the turbine into a torque, the liquid still contains residual energy.
  • the liquid emerging from the small radial outlet 44 would normally enter the pump counter to the direction of rotation of the pump.
  • the stator 39 serves to redirect the liquid to accelerate the pump and thereby increase the torque ratio.
  • the stator 39 is connected by a freewheel 46 with the stator shaft 45.
  • the stator shaft is connected to the transmission housing 47 and does not rotate.
  • the freewheel 46 prevents the stator 39 from rotating at low speed ratios (when the pump is turning faster than the turbine).
  • the liquid entering the stator 39 from the outlet 44 of the turbine is deflected by the stator blades 48 and enters the pump 37 in the direction of rotation.
  • the inlet and outlet angles of the blades, the shape of the pump and turbine shell, and the overall diameter of the torque converter affect its performance parameters.
  • parameters such as e.g. The torque ratio, the efficiency and the ability of the torque converter to absorb the torque of the engine without the engine being able to "spin" is a factor that happens when the torque converter is too small and the pump can not decelerate the engine.
  • the torque converter operates satisfactorily by letting the engine run while the vehicle is stationary and increasing the torque of the engine for increased performance.
  • the torque converter does not affect so much.
  • the torque of the torque converter gradually returns from a high value of about 1.8 to 2.2 to a torque ratio of about 1 as the speed of the turbine approaches the speed of the pump.
  • a torque ratio of 1 is referred to as the engagement point.
  • the liquid entering the stator no longer needs to be redirected, and the free-wheel in the stator allows the liquid to rotate in the same direction as the pump and the turbine. Since the stator does not redirect the fluid, the output torque of the torque converter is equal to the input torque.
  • the entire fluid circuit turns as a unit. - A -
  • a torque converter clutch 49 is used, which connects the input of the torque converter to the output and increases the efficiency to almost 100%.
  • a clutch piston plate 17 is operated.
  • the piston plate 17 is sealed at its inner diameter by an O-ring 18 against the turbine hub 19 and at its outer diameter by a ring 51 made of friction material against the lid 11. These seals create a pressure chamber and press the piston plate 17 against the lid 11. By this mechanical connection of the fluid circuit of the torque converter is bypassed.
  • the mechanical connection of the torque converter clutch 49 transmits much more torque fluctuations of the engine to the powertrain. Since the powertrain is basically a spring-mass system, torque fluctuations of the engine can excite system resonance frequencies. To shift the resonance frequencies of the drive train from the driving range, a damper is used.
  • the damper includes serially arranged springs 15 to reduce the effective spring rate of the system and thereby reduce the resonant frequency.
