Definitions

  • the present invention relates to torque limiters positioned between the engine and the transmission units in vehicles, in particular in vehicles having internal combustion engine.
  • Torque limiters are positioned between the engine and transmission units in internal combustion vehicles. Torque limiters prevent the excessive torque from being transmitted to the transmission units when the torque, obtained in the engine, is greater than a specific value. Accordingly, a drive disc is compressed between the plates and controls the transfer of the torque. In more details, the drive disc extends towards between a first cover and a second cover. There are friction linings at the two sides of the part of the drive disc which remains between covers. A pressure plate provided in the vicinity of the drive disc is pushed by a diaphragm spring and exerts pressure onto the drive disc. In other words, the drive disc is compressed between the pressure plate and one of the covers.
  • the extensions provided on the outer wall of the pressure plate enter into the housings provided on the covers.
  • the covers are formed. Forming of the covers leads to changing of shape of the housing. This leads to a difference from the desired dimension of the housing and this leads to movement of the extensions inside the housing in an undesired manner. This leads to undesired performance changes during movement transmission.

  • An object of the present invention is to provide a torque limiter with facilitated production and with reduced material cost.

  • Figure 3 is the representative isometric view of the pressure plate of the subject matter torque limiter.
  • Figure 4 is the representative isometric view of the diaphragm spring of the subject matter torque limiter.
  • the subject matter torque limiter 10 has a first cover 20 and a second cover 30.
  • the diaphragm spring 40 rested to the first cover 20 pushes the pressure plate 50 and provides the friction linings 61 to be compressed between the pressure plate 50 and the second cover 30.
  • At least one extension extends inwards a housing 51 provided on the other one of the first cover 20 and of the pressure plate 50.
  • the extension 21 is at least partially placed into the housing 51 .
  • the extension 21 is provided on the inner wall of the first cover 20.
  • the extension 21 is essentially obtained by means of bending a part of the first cover 20 towards the side where the pressure plate 50 is provided.
  • the housing 51 is provided on the pressure plate 50.
  • the housing 51 can be provided in the form of a recess provided on the inner wall of the pressure plate 50 or in the form of a hole formed on the pressure plate 50.
  • Pluralities of extensions 21 and housings 51 are provided within a multiple arrangement.

  • the extension 21 extending towards the housing 51 provided on the pressure plate 50 also passes through the centering housing 41 at the same time. Besides centering, the rotation of the diaphragm spring 40 is prevented thanks to the extension 21 .
  • the pressure plate 50 is remained in a concentric manner with the torque limiter 10. Moreover, since there is no additional shaping with the part where the housing 51 is formed, the form of the housing 51 is protected and the extension 21 can be fixed into the housing 51 with the desired precision.
  • the movement is transferred, thanks to the friction linings 61 , between the drive plate 60 and, the pressure plate 50 and the second cover 30.

In other words, when compared with the prior art, the rotation which can be realized by the pressure plate 50 with respect to the second cover 30 is decreased or prevented. Since the extensions 21 are provided on the first cover 20 or on the inner wall of the pressure plate 50, the outer diameter of the pressure plate 50 can be provided in a smaller form in a different manner from the prior art. In other words, the pressure plate 50 can be made of smaller sized material. There is no loss of place radially outside the pressure plate.
  • the housings 51 are formed on the inner wall of the first cover 20 or on the pressure plate 50 in a different manner from the prior art, there remains no need to realize emptying at the bent parts of the first cover 20 and of the second cover 30. Thus, the production of the first cover 20 and of the second cover 30 is facilitated and the resistances thereof are increased.
  • the diaphragm spring 40 By means of the passage of extensions 21 through the centering housings 41 which are provided on the diaphragm spring 40, the diaphragm spring 40 is positioned in a concentric manner with the torque limiter 10. Thus, there remains no need to use the outer wall of the diaphragm spring 40 for centering of the diaphragm spring 40. Thanks to this, changing of the radiuses at the bending parts of the first cover 20 in the desired manner is possible.
  • the first cover 20 and the second cover 30 are connected to the internal combustion engine of the vehicle.
  • the drive plate 60 is connected to a damper connected to the transmission units.
