  • Patent number: 11845532
    Abstract: Embodiments provide a propeller ground stop mechanism configured to keep an unpowered propeller of an aircraft (e.g. when the aircraft is on the ground and not operating) static. The propeller is prevented from rotating due to external forces (e.g. an air flow caused by wind, manual rotation of the propeller). When the propeller is powered, and the propeller is providing thrust, the propeller ground stop mechanism automatically disengages and does not provide any drag. Among various benefits, the propeller ground stop mechanism provides added safety to the ground support personnel.

  • Patent number: 10066688
    Abstract: Disclosed is a caliper brake apparatus. The caliper brake apparatus includes: a housing that includes a piston capable of moving straight; a carrier that is combined with the housing and mounted on a vehicle such that a disc of the vehicle is positioned therein; a pair of pad plates that is brought in close contact with the disc by straight movement of the piston; and a pair of guides that couple the pad plates and the carrier to each other, in which the pad plates each may have a sliding groove at both sides and the guides each have elastic members that can slide along the sliding grooves. Accordingly, it is possible to ensure sufficient gaps between a disc of a vehicle and the pad plates when the pad plates are separated from the disc after being strongly pressed to the disc of a vehicle.

  • Patent number: 9046141
    Abstract: A body for a disc brake caliper has a mounting side limb and a non-mounting side limb, each limb housing at least one hydraulic brake cylinder. The body has a peripheral stiffening band that extends about an outer lateral surface of at least one of the limbs. In a preferred embodiment, a peripheral stiffening band extends about an outer lateral surface of each of the limbs. The stiffening band or bands provide stiffness in the body under dynamic braking conditions with a minimum of material. A method of designing and manufacturing a body for a disc brake caliper involves analyzing the stiffness of the body under dynamic rather than static braking conditions and producing a caliper body with a desired level of stiffness under dynamic conditions while reducing the amount of material used to a minimum.
