Patent number: 11268577Abstract: In a vehicle cam damper structure, a drive shaft includes a cam damper at a midway portion thereof. The cam damper integrates a cam reception portion with a cam via a shaft member. The cam reception portion is connected relatively rotatably with the shaft member. The cam and the shaft member, while being integrally rotatable, are connected with each other axially slidably. The shaft member includes an enlarged-diameter portion. An elastic member that presses the cam toward a side of the cam reception portion is disposed between the enlarged-diameter portion and the cam. An outer cylinder extends across the cam reception portion and the shaft member. A drive-side shaft and a driven-side shaft of the drive shaft are each connected with corresponding one of the cam reception portion and the shaft member.Type: GrantFiled: September 19, 2019Date of Patent: March 8, 2022Assignee: HONDA MOTOR CO., LTD.Inventors: Koji Sato, Akio Handa, Keita Yagi, Dai Arai, Eiichi Suzuki, Takeyuki Kariyasu

Patent number: 11059518Abstract: In a vehicle frame structure, upper ends of a front frame and a rear frame, which connect a lower frame and an upper frame vertically, are connected to each other above the upper frame, and a front portion frame assembly is connected to a main frame assembly via the lower frame and the upper ends of the front and rear frames. A bumper includes a front-rear frame portion extending forward from the front frame, and an inclined frame portion arranged between an intermediate portion of the front frame and an end portion of the front-rear frame portion. The bumper includes a sub-bumper, the sub-bumper including a front sub-frame extending upward from a front end of the bumper, and a front-rear sub-frame connected between an end portion of the front sub-frame and an intermediate portion of the front frame above the upper frame.Type: GrantFiled: September 19, 2019Date of Patent: July 13, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Takeyuki Kariyasu, Takeshi Kamiyama, Masayuki Hirukawa, Yuji Maki, Ryota Yamagishi

Patent number: 9586514Abstract: In a vehicle with a load-carrying platform, an elastic band is provided so a rear portion of a tailgate and a rear portion of a bed extender enter a tensioned state. A rotation regulation mechanism is provided to the tailgate and the bed extender that regulates further rotational movement by the tailgate and the bed extender making contact when the tailgate is rotated towards a closed position. The bed extender and the tailgate are prevented from rotating in the same direction by the rotation regulation mechanism, and the load on the elastic band is mitigated.Type: GrantFiled: March 21, 2016Date of Patent: March 7, 2017Assignee: Honda Motor Co., Ltd.Inventors: Kosuke Asao, Takeshi Kobayashi, Hiroyuki Nishimori, Makoto Hotozuka, Yuji Maki, Takeyuki Kariyasu, Hiroyuki Shinmura, Masanori Aoki

Patent number: 8196696Abstract: A vehicle frame structure includes a central frame member, extending in a vehicle longitudinal direction at a central portion of a body frame. The central frame member includes a front end joined to a second front cross pipe, and a rear end joined to a second lower crossmember behind the second front cross pipe. When viewed from the side, the central frame member extends in a substantially straight line along with the left and right front reinforcing pipes. The front end portion of the central frame member is joined to the second front cross pipe at a position inwardly of a joint between the left front reinforcing pipe and the second front cross pipe, and inwardly of a joint between the right front reinforcing pipe and the second front cross pipe. Such frame structure lowers level of a center of gravity of the vehicle, and enhances rigidity.Type: GrantFiled: July 29, 2010Date of Patent: June 12, 2012Assignee: Honda Motor Co., Ltd.Inventors: Shinichi Karube, Toshiyuki Suzuki, Hiroyuki Kido, Ryota Yamagishi, Takeyuki Kariyasu, Naoki Kuwabara
