    Abstract: A metal collar attached in a through-hole of FRP member includes first and second collar members. The first collar member includes outer and inner circumferential surfaces. The outer circumferential surface is in contact with a hole inner circumferential surface of the through-hole. A slit is formed in a part in a circumferential direction of the first collar member. The second collar member applies a pressing force radially outward to at least a part of the inner circumferential surface of the first collar member or a pressing force to inner surfaces of the slit in a direction in which the inner surfaces separate from each other in the circumferential direction. The second collar member is held in the first collar member by reaction of the pressing force, deforms the first collar member for diameter expansion with the pressing force, and presses the outer circumferential surface against the hole inner circumferential surface.

    Abstract: A grid spring is provided with first raised pieces that generate an elastic force for pressing a separator toward a power generation cell and second raised pieces that generate an elastic force independently of the first raised pieces. The spring constant of the first raised pieces decreases as a result of heating of a grid spring. The grid spring functions as a high reaction force spring as a result of a larger spring constant of the first spring member relative to a spring constant of the second spring member before heating. After being heated, the grid spring functions as a low reaction force spring as a result of the smaller spring constant of the first spring member before being heated.

  • Patent number: 11400932
    Abstract: A target vehicle speed generation device includes a controller for generating a target vehicle speed of a host vehicle in accordance with a speed limit of a travel path of the host vehicle. The controller includes a speed limit information acquisition unit and a target vehicle speed generation unit. The speed limit information acquisition unit acquires the speed limit of the travel path of the host vehicle during travel. The target vehicle speed generation unit generates a target acceleration together with the generation of the target vehicle speed in accordance with the speed limit. The target vehicle speed generation unit has a first acceleration limiter computation unit that, during the generating of the target acceleration, sets an acceleration limiter to increase in a direction of relaxing a limitation on acceleration correspondingly with an increase in the speed limit.

  • Publication number: 20220234456
    Abstract: A generator of a hybrid electric vehicle is electrically connected with an inverter by a harness. A generator opening is opened on a generator housing, and an inverter opening is opened on an inverter housing. The harness extends between the generator opening and the inverter opening. The harness is led out from the inverter opening in a first direction toward the generator. The harness is led out from the generator opening in a second direction that is different from the first direction. The inverter opening is set off with respect to the generator opening in the second direction, and at least a portion of the harness extends between the generator housing and the inverter housing. The harness necessarily flexes, and thereby deters transmission of vibrations from the generator to the inverter.

    Abstract: A suspension element of a vehicle includes a coil spring, and a bearing part provided with a main stop. The spring is mounted on the bearing part in such a manner that a first end of the spring comes to bear against the main stop. The bearing part includes a secondary stop placed in front of the main stop, against which secondary stop the first end of the spring bears during a method for assembling the suspension element. The secondary stop is capable of moving away under the effect of pressure exerted by the spring on the secondary stop during a stage of compressing the spring after the spring has pivoted about the spring's rotational axis during a stage involving straightening the spring, so that a second end of the spring is made to interact with a centering element, in order to come to bear against the main stop.
