  • Patent number: 8905169
    Abstract: An exterior cover (shroud) for a saddle-type vehicle is formed by integrally uniting a plurality of resin members including a front cover section and a rear cover section. The shroud is insert molded to form an overlapping part where the front cover section and the rear cover section overlap with each other. The front cover section has an external-appearance-surface side at the overlapping part. The rear cover section has a non-external-appearance-surface side, which overlaps with the front cover section at the overlapping part. The rear cover section has a rib extending on the non-external-appearance-surface side. Such exterior cover prevents a sink mark from being generated in the external appearance surface of the front cover section, and improves the external appearance of vehicle.

  • Patent number: 8825308
    Abstract: An opening/closing control device for a grille shutter is capable of appropriately opening and closing the grille shutter according to a vehicle outside environment and an operating state of an aircon while ensuring the operation of the aircon, and is capable of sufficiently improving vehicle operating efficiency. An aircon operating time ratio as a ratio of operation time of an aircon to overall time is calculated. When the calculated aircon operating time ratio is larger than the sum of a threshold value calculated according to an ambient air temperature and a hysteresis constant, the grille shutter is opened to promote cooling of refrigerant in the aircon and reduce motive power consumed by the aircon. Therefore, it is possible to appropriately open and close the grille shutter depending on the ambient air temperature and the operating ration of the aircon.

  • Publication number: 20140238759
    Abstract: Provided is a construction machine including a guard panel with an air suction port and capable of ensuring a required intake opening area with suppressed disadvantages of the air suction port. The construction machine includes an engine, a cooling fan, and a heat exchanger which are accommodated in a device accommodation space in an upper slewing body, and a guard panel covering the device accommodation space. The guard panel includes a first panel with an opening edge defining an opening and a second panel that opens and closes the opening and has a peripheral portion to be supported by the opening edge with the opening closed. Respective parts of the peripheral portion and the opening edge are shifted from each other in an inward-outward direction to form an air suction port bringing the device accommodation space into communication with outside, between the second panel and the first panel.

  • Patent number: 8807255
    Abstract: An engine hot air deflector for a work machine having an articulated frame pivotally coupled to a main body by a hitch assembly having a hitch link includes a resilient hot air deflector panel mounted proximate to and overlaying an open end of the main body. The deflector panel includes upper and lower panel portions separated by a panel slot. The panel slot receives the hitch link so that the panel portions conform to the shape of the hitch link as it moves within the deflector opening during rotation of the articulated frame to substantially prevent hot air from the internal combustion engine from passing through the deflector opening. The deflector may also include a support bracket mounting the deflector panel to the main body.
