  • Patent number: 10504500
    Abstract: In a vehicle wheel, communication holes of first Helmholtz resonators (auxiliary air chamber members) having a resonant frequency lower by a first prescribed frequency ?fa than the resonant frequency of air column resonance sounds of a tire, and communication holes of second Helmholtz resonators having a resonant frequency higher by a second prescribed frequency ?fb than the resonant frequency of air column resonance sounds of the tire, are arranged facing each other across the wheel rotational center, the second prescribed frequency ?fb being set greater than the first prescribed frequency ?fa.

  • Patent number: 10479137
    Abstract: A vehicle wheel is provided which includes a sub air chamber member capable of suppressing a surface deformation amount in case of an action of an internal pressure of the sub air chamber member. A sub air chamber member of a vehicle wheel includes an upper surface member, a lower surface member, and bridge sections causing the upper surface member and the lower surface member to strike on each other. An end-to-end distance of an opening part of a bridge section opening on an upper surface of the upper surface member is set longer than a distance to an end portion of an opening part of another bridge section adjacent thereto. Moreover, the area of the opening parts of the bridge sections opening on the upper surface of the upper surface member is larger than the area of other general parts.

  • Patent number: 9586296
    Abstract: A guide rod, which has a diameter expandable tip end portion and restricts the oscillation of a connecting rod and a piston, is inserted into a cylinder bore via an opening adjacent to a crank chamber of the cylinder bore, and the piston is inserted into the cylinder bore via a cylinder head mounting side opening with the connecting rod positioned at a leading end. The diameter of the tip end portion of the guide rod is increased in a hole of a semi-circular arc-shaped end portion positioned at tip end of the connecting rod in the insertion direction, and thus the connecting rod is engaged with the guide rod. The guide rod moves and the connecting rod is pulled into the cylinder bore until the semi-circular arc-shaped end portion of the connecting rod sits on a crankpin of a crankshaft.

  • Patent number: 5171966
    Abstract: A welding torch (4) of a welding robot (RO) is supported by arms (2, 3), to be movable under control by a computer (7). When first and second members (W1, W2) are welded by a weld woven across an interspace between them while oscillating a welding torch (4) along a weld line (WL). Data on changes in the interspace between the first and second welded member (W1, W2) along direction of the weld line (WL) are previously stored in advance to welding. During the welding, the computer 7 performs arithmetic to obtain command values on the basis of the data to output the same to the welding robot (RO), so that the welding robot (RO) performs weaving in accordance with the command values while varying a weaving amplitude of the welding torch (4) in response to the change in the interspace. Changes in the direction in which the welding torch is moved to weave the weld are determined by detecting the actual value of the welding current and reversing direction when the detected value exceeds a prescribed threshold value.

  • Patent number: 4896921
    Abstract: The wheel of the present invention reduces road noise without using a special tire. The wheel includes a wheel body and a silencing chamber formed around the wheel body. The silencing chamber communicates with an air chamber in the tire via communication port. The phase difference between a compressional wave in the air chamber and a compressional wave returned to the air chamber from the communication port cause attenuation of the road noise.

  • Patent number: 4870247
    Abstract: A welding torch (4) of a welding robot (RO) is supported by arms (2, 3), to be movable under the control of a computer (7). First and second members (W1, W2) are welded by a mold woven while oscillating an welding torch (4) along a weld line (WL), with data on changes in an interspace between the first and second welded members (W1, W2) along a direction of the weld line (WL) being previously obtained and stored in advance of welding. For the welding, the computer 7 performs arithmetic to obtain command values on the basis of the stored data to output the same to the welding robot (RO), so that the welding robot (RO) performs weaving in accordance with the command values while varying a weaving amplitude of the welding torch (4) in response to the change in the interspace.
