Abstract: A caliper brake system includes a housing, a bore within the housing, and a piston slidably positioned within the bore. The brake system also includes a spring assembly, a fluid chamber defined by the bore and the piston, and a hydraulic fluid supply network. The spring assembly provides a biasing force to maintain the piston in an actuated position engaging a stator which engages the rotor of a vehicle. The hydraulic fluid supply network provides pressurized fluid to the fluid chamber to selectively overcome the biasing force of the spring assembly and move the piston to an unactuated position to release the rotor. Thus, the caliper brake is spring actuated and hydraulically released.

The brake apparatus includes: (a) a power drive device; (b) a driven member that is to be moved, by the power drive device, relative to the piston in the axial direction; and (c) an engaging portion that is provided in one of the driven member and the piston, such that the piston is held in engagement with the driven member through the engaging portion. The engaging portion is disposed such that, during release of the application of the brake, the piston is movable rearwardly while being held in engagement with the driven member through the engaging portion.

Abstract: A cast iron brake caliper with improved fatigue life, and a process and process equipment for pre-stressing a cast iron brake caliper to provide improved fatigue life, is provided. In the process, a load is applied to a cast iron caliper, where the load is high enough to locally yield and plastically deform the cast iron material, but not high enough to cause material failure, such as cracking. Upon load removal, residual compressive stresses in the cast iron caliper lower the mid-point of the stress range the plastically-deformed region of the caliper sees during in-service use, and thereby lowers the peak stress seen in this region, increasing fatigue life. The process permits a cast iron brake caliper to be designed to use less material and thus fit within constrained wheel rim envelopes, without the need to resort to high cost materials or other alternative design strategies.

Abstract: The bottom surface of a seal groove provided in a cylinder bore has a first slant portion and a second slant portion. A transition point between the first slant portion and the second slant portion is located closer to the opening of the cylinder bore than the center in the cylinder bore axial direction of the seal groove. A gap is formed between the outer peripheral surface of a piston seal member and the bottom surface of the seal groove, and the surface pressure applied to the bottom surface of the seal groove from the piston seal member is higher at the cylinder-bottom-side end of the piston seal member than at the cylinder-opening-side end thereof. Thus, it is possible to suppress the movement of the piston toward the cylinder bore bottom due to thermal expansion of the piston seal member.

Abstract: [Problem] A parking brake control device can ensure required braking force and reliably allow release even if an automatic pressurization function that increases a W/C pressure is malfunctioning, regardless of operation of a brake pedal. [Solution] If an ESC is malfunctioning when a locking control or a releasing control of a parking brake is being performed, a depression request for a brake pedal is output to a driver. As a result, when the ESC is malfunctioning, namely, even if an automatic pressurization function of a service brake is malfunctioning, a W/C pressure can be increased by the driver depressing the brake pedal. Thus, it is possible to ensure required braking force at times when the locking control is being performed, and also possible to reliably release when the releasing control is being performed.

Thus, strain energy of the carrier is absorbed through warpage deformation of the torsion pins, so that the carrier has sufficient strength even if an outer beam is removed.
