  • Disk rotor of vehicle brake
    Patent number: 11549561
    Abstract: A disk rotor of a vehicle brake with improved efficiency in cooling the disk rotor by a synergy effect that comes from ensuring velocity of airflow flowing between cooling fins, ensuring surface areas of the cooling fins, and generating turbulent flow by second fins. A plurality of cooling fins each extending radially from an inner peripheral edge to an outer peripheral edge of a disk rotor are provided inside the disk rotor at intervals in the circumferential direction. Each of the plurality of the cooling fins includes a radial fin extending radially and a second fin spaced apart from the radial fin in the radial direction.
    Type: Grant
    Filed: October 6, 2020
    Date of Patent: January 10, 2023
    Assignee: MAZDA MOTOR CORPORATION

  • Grille shutter control device of vehicle
    Patent number: 10611235
    Abstract: A grille shutter control device of a vehicle includes an encapsulation structure covering an engine, a grille shutter provided at an opening formed at a front wall portion of the encapsulation structure, an actuator configured to move the grille shutter to open/close the opening, and a controller configured to control the actuator. The controller determines whether or not heat damage occurs on a related component relating to the engine upon key OFF, closes the grille shutter upon key OFF in the case of determining that the heat damage will not occur, and opens the grille shutter upon key OFF in the case of determining that the heat damage will occur.
