During the vehicle braking, the non-rotatable brake pad presses against the rotating brake rotor, producing friction heat on frictional contact bands where the brake rotor and the brake pad engages with each other. A plurality of longitudinal vortex generators configured in fins is mounted either to a rotatable vehicle component such as hat of a brake rotor, or a non-rotatable vehicle component such as a protective plate, generating longitudinal vortices in the cooling air flows around the brake rotor, especially across the hottest frictional contact bands. The induced longitudinal vortices in the cooling air flows optimize the heat dissipation from brake rotor into atmosphere.Type: ApplicationFiled: January 3, 2019Publication date: July 9, 2020Inventor: Ming Zhang

Publication number: 20200217379Abstract: An electric motor-driven brake apparatus has speed reduction mechanisms transmitting rotational force of an electric motor, a ball screw mechanism converting rotational force of the speed reduction mechanisms into a thrust, a piston propelled by the ball screw mechanism, and a caliper movably supporting the piston. The ball screw mechanism has a base nut non-rotatably supported relative to the caliper. The ball screw mechanism further has a push rod receiving rotational force from the speed reduction mechanisms. The push rod is movable relative to the base nut in the axial direction of the push rod. Consequently, it is possible to reduce the axial length of the cylinder portion of the caliper body, and hence possible to attain a size reduction. Accordingly, it is possible to improve the mountability of the electric motor-driven brake apparatus 1 onto vehicles.Type: ApplicationFiled: September 18, 2018Publication date: July 9, 2020Inventor: Atsushi ODAIRA

Publication number: 20200217386Abstract: Apparatus and methods to reduce unwanted motion in precision instruments are described. An active vibration-isolation system may include a feedback loop that senses motion of an intermediate mass. In noisy environments, where the feedback loop would otherwise fail or provide inadequate isolation, feedforward control can be implemented to sense floor vibrations and reduce motion of the intermediate mass that would otherwise be induced by the floor vibrations. The feedforward control can reduce motion of the intermediate mass to a level that allows the feedback loop to operate satisfactorily.Type: ApplicationFiled: August 15, 2018Publication date: July 9, 2020Applicant: Technical Manufacturing CorporationInventors: Igor Kordunsky, Jeffrey L.
