Definitions

  • the invention relates to a floating caliper brake with the features of the preamble of claim 1.
  • Floating caliper brakes are known per se. They have a transversely displaceable to the brake disc, so-called. Floating caliper, in which a friction brake pad firmly on one side of the brake disc, ie rests immovably. A floating caliper movable friction brake pad is disposed on the other side of the brake disc and is pressed to actuate the floating caliper brake with an actuator against the brake disc. By pressing the movable friction brake lining against one side of the brake disk, the floating caliper is displaced transversely to the brake disk and presses the fixed friction brake lining against the other side of the brake disk.
  • the actuating device can be, for example, hydraulic, pneumatic or electromechanical.
  • Electromechanical floating caliper brakes typically include an electric motor, a reduction gear, and a rotation / translation conversion gear for urging the movable friction pad against the brake disk.
  • the rotation / translation conversion gear can be a screw drive or, for example, also a pivoting cam, which by pivoting the movable friction brake pad presses against the brake disc.
  • linear electromechanical actuators with, for example, an electromagnet or a piezo element for pressing the movable friction brake lining against the brake disc are possible.
  • the floating caliper brake may include a self-energizing device that converts a frictional force applied to the friction brake pad against the brake disk pressed against the rotating brake disk into a pressing force that presses the friction brake pad against the brake disk in addition to a pressing force applied by the actuator.
  • the braking force is thereby increased.
  • Mechanical self-energizing devices include, for example, a wedge or ramp mechanism that supports the movable friction brake pad at an angle to the brake disk in the caliper. The support causes a support force with a force component perpendicular to the brake disc, which represents the additional pressure force.
  • Ventilation means a gap between the brake disc and the friction brake linings.
  • a sealing ring which seals a hydraulic piston in a cylinder in the floating caliper causes the clearance. If the movable friction brake lining with the hydraulic piston is pressed against the brake disk, the sealing ring, for example a square or quad ring, deforms elastically. When releasing the floating caliper brake, the sealing ring resumes its original shape, moving the hydraulic piston away from the brake disc by the clearance. The movable friction brake pad either moves with the hydraulic piston or it is still loosely against the brake disc.
  • the floating caliper is not moved, ie between the fixed friction brake pad and the brake disc is no clearance.
  • electromechanical floating caliper brakes usually moves the electromechanical actuator, the movable friction brake pad back to its original position, wherein it lifts the movable friction brake pad from the brake disc and thus adjusts a clearance. Again, no clearance between the fixed friction brake lining and the brake disc is adjusted by a movement of the floating caliper transversely to the brake disc.

  • the retraction lock operates linearly, ie the relative movement is a linear movement, but preferably not necessarily a straight motion.

  • the retraction lock according to the invention allows movement in the direction of actuation of the floating caliper brake and blocks against movement in the release direction. The size of the clearance thus adjusts itself and it causes a wear adjustment.
  • the invention has the advantage that when releasing the floating caliper brake on both sides of the brake disc a clearance between the brake disc and the friction brake pads, not necessarily the same size, clearance is set. A residual braking torque is avoided, as well as grinding the friction brake linings on the brake disc, especially when cornering, at least if the friction brake linings moved along and not only the floating caliper and the actuator are reset. Especially with a stiff floating caliper, the invention has the advantage of lifting both friction brake linings from the brake disc, so that the brake disc is freely rotatable and no lining wear occurs.
