Abstract
The present invention discloses a clutch with torque converter clearance that prevents internal interference with the components of the torsional vibration filtering device, and also allows an easy and quick evaluation of the clutch clearance around 360° of the piston when the clutch is engaged. To achieve the above, a normally coupled clutch with torque converter clearance comprising a piston cap; at least one friction disc; and a piston is implemented; the piston in turn comprises a pressure plate and a cover core, where the cover core comprises a mechanical stop or retainer as main element.
Claims19
A clutch with torque converter clearance comprising:
- a piston cap;
- at least one friction disc;
- and a piston;
- the piston in turn comprising a pressure plate and a cover core, the pressure plate being configured to apply pressure on each friction disc to connect a cover with a torsional vibration filtering device, the cover core is connected to the cover;
- wherein the clutch is characterized in that the cover core comprises in turn a mechanical stop being configured to limit an axial movement of the pressure plate and being configured to have a clearance with the pressure plate.
A torque converter comprising:
- a cover that is configured to receive a rotational motion from an engine, the cover is assembled with a pump housing;
- the pump housing being configured to receive the rotational movement of the cover, the pump housing is connected to an impeller;
- the impeller transferring the rotational motion to a turbine;
- the turbine transferring the rotational motion to a torsional vibration filtering device;
- the torsional vibration filtering device receiving rotational motion from the turbine and being configured to transfer rotational motion to a transmission;
- a clutch that being configured to allow a coupling between the cover and the torsional vibration filtering device, the clutch comprising a piston cap, and at least one friction disc;
- and a piston which, in turn, comprises a pressure plate and a cover core, the pressure plate being configured to apply pressure on each friction disc to connect the cover with the torsional vibration filtering device, the cover core is connected to the cover;
- wherein the torque converter is characterized in that the cover core comprises in turn a mechanical stop being configured to limit an axial movement of the pressure plate and being configured to have a clearance with the pressure plate.
