Abstract: Disclosed is a brake disc rotor comprising a first disc plate, a second disc plate facing the first disc plate, a plurality of fins arranged in the radial direction of the brake disc rotor between the first and second disc plates, and a plurality of ventilation holes each of which is positioned between neighboring fins of the plurality of fins and communicates a space on the inner circumferential side and a space on the outer circumferential side in the radial direction of the brake disc rotor. The plurality of fins have a plurality of sets each including two long fins and two short fins, one of the two long fins has an expanded part which is expanded in its width direction, the long fins and the short fins are alternately arranged in the circumferential direction of the brake disc rotor in each of the plurality of sets, and the plurality of sets are arranged at equal intervals in the circumferential direction of the brake disc rotor.

Abstract: An outer surface 1d of the brake drum 1 has seven thick portions (10B1 to 10B7) each having equal mass and separated at an equal distance in the circumferential direction from a reference line which is an arbitrary diameter, six thick portions (10C1 to 10C6) each having equal mass and separated at an equal distance in the circumferential direction from the same reference line, five thick portions (10D1 to 10D5) each having equal mass and separated at an equal distance in the circumferential direction from the same reference line, and four thick portions (10E1 to 10E4) each having equal mass and separated at an equal distance in the circumferential direction from the same reference line. Accordingly, the outer surface (1d) of the brake drum (1) has a plurality of thick portions which can be classified into four groups (10B1 to 10B7, 10C1 to 10C6, 10D1 to 10D5, and 10E1 to 10E4), each group having equal mass.

Abstract: In the disk brake, mounting portions of the caliper of a disk brake extending toward the entrance side and the exit side with respect to the rotation direction of the disk. Relative to the rotation direction, the length of the mounting portion on the entrance side is greater than that of the mounting portion on the exit side so that the cylinder portion is offset toward the exit side. Further, the mounting portion on the entrance side has thickenings formed to extend in a longitudinal direction thereof, so that with respect to the direction of the axis of the disk, the thickness of the mounting portion on the entrance side is greater than that of the mounting portion on the exit side. During braking, when a bending moment acts on the caliper, which can cause inclination of the caliper relative to the disk, flexural rigidity of the mounting portion on the entrance side is higher than that of the mounting portion on the exit side.

Abstract: In the ventilated holes of the brake ventilated rotor are formed seven thick portions each having equal mass and separated at an equal distance in the circumferential direction from a reference line which is an arbitrary diameter, six thick portions each having equal mass and separated at an equal distance in the circumferential direction from the same reference line, five thick portions each having equal mass and separated at an equal distance in the circumferential direction from the same reference line, and four thick portions each having equal mass and separated at an equal distance in the circumferential direction from the same reference line. In other words, in the ventilating holes of the ventilated rotor are formed a plurality of thick portions which can be classified into four groups, each group having equal mass. The thick portions in respective groups are arranged at an equal distance in the circumferential direction.

Abstract: An active noise eliminating system comprises microphones for detecting residual noise, speakers for generating noise elimination sound for interference with the residual noise, a noise generating condition sensor for generating noise condition, a controller for generating noise elimination signals inputted to the speakers and determined by the detected residual noise signals and the detected noise condition signal in accordance with a control algorithm including transfer functions between the speakers and microphones respectively. The transfer functions are updated on the basis of a test signal generated when noise sound diverges.

Abstract: An apparatus for reducing periodical noises transmitted from a noise source into a vehicle passenger compartment. The apparatus comprises control sound sources for producing control sounds in the vehicle passenger compartment, residual noise sensors for detecting the residual noises in the vehicle passenger compartment, transfer function filters modeled on transfer function between the control sound sources and the residual noise sensors, and adaptive digital filters having variable filter coefficients. A reference signal is produced in the form of a series of impulses having the same period as the noises. The transfer function filters are convoluted with the reference signal to produce reference processed signals. The adaptive digital filters are convoluted with the reference signal to generate drive signals to drive the control sound sources.
