  • Patent number: 8925698
    Abstract: A brake cylinder includes a pressure medium actuated brake piston delimiting a brake chamber and connected to a brake piston rod. The brake piston, together with the piston rod, swivels into positions tilted from a center axis of the brake cylinder during an actuation stroke. The brake piston is rigid and has a guide surface in the shape of a spherical surface of an imaginary sphere on its radially outer peripheral surface. The guide surface is guided along a radially inner cylinder wall of the brake cylinder with the center of the sphere lying on the center axis of the brake cylinder. The brake piston further has at least one elastic sealing element radially displaceable in a radially outer annular groove of the brake piston and delimiting an annular space together with a groove base of the annular groove on its side facing away from the radially inner cylinder wall.

  • Patent number: 7610827
    Abstract: An adjusting device for a transmission, such as a motor vehicle transmission is described. The transmission has at least one moveable adjusting element, at least two sensors for detecting a position of the at least one moveable adjusting element, and a code path of the at least one moveable adjusting element having sections of different heights which are provided to be scanned by the at least two sensors, the sections of the code path of different heights being arranged at least two-dimensionally. The at least two sensors are arranged parallel to one another.

  • Patent number: 7543515
    Abstract: An adjusting device for a transmission is described. The device has at least one movable adjusting element, a plurality of sensors for detecting a position of the at least one movable adjusting element, which are arranged substantially parallel to one another, and a plurality of cam paths having sections of different heights, assigned to corresponding ones of the plurality of sensors. The device also includes a plurality of scanning elements coupled to the plurality of sensors for mechanically scanning the sections of different height, and at least one catch of each of the plurality of cam paths in which a latching element is engageable, wherein the plurality of sensors and the latching element are designed as a common component. The plurality of cam paths result in comparable stroke movements arising for each of the plurality of scanning elements.
