Definitions

  • the present invention relates to an actuator for the drive train of a motor vehicle, in particular for the automation of a manual transmission according to the preamble of patent claim 1.
  • the present invention has for its object to provide actuators for the drive train of a motor vehicle, in particular for the automation of a gearbox, which do not have the above-mentioned disadvantages of the actuators known from the prior art.
  • the actuators according to the invention are intended to require little installation space and have a simple design, with the intention of avoiding the use of transmissions for movement conversion.
  • the geometry is varied in response to an electric field applied to the materials, the strain being proportional to the square of the locally applied field in the crystal structure. According to the invention, this property is to be used to realize the automation of a manual transmission.
  • Electrostrictive actuators are characterized by a particularly high energy density, such that the actuators according to the invention can be arranged directly at the desired location.
  • the actuator for clutch automation may be formed as an annular Gottausscher acting directly on the release bearing of the clutch.
  • a rod-shaped or block-shaped actuator made of an electrostrictive material can act directly on the sliding sleeve to be switched.
  • the actuators are preferably made of electrostrictive polymers which have very good electrostrictive properties.
  • the realization of the automation of a manual transmission is made possible in a simple manner and with low space requirements.
  • the actuators according to the invention can replace other conventional actuators present in the drive train of a vehicle.
