Patent number: 10906369Abstract: A vehicle front end assembly includes an engine cradle, a transverse link and a fastener. The engine cradle has an upper attachment portion and a lower attachment portion, both being rigidly attached to the engine cradle. The upper attachment portion has a recessed area that includes a first opening extending through the recessed area. The upper attachment portion has a first overall thickness with a portion of the recessed area surrounding the first opening having a second thickness that is greater than the first thickness. The lower attachment portion has a second opening below the first opening. The transverse link has an inboard portion with a third opening that extends through the inboard portion. The fastener passes through the first opening, the third opening and the second opening such that the fastener retains the transverse link to the upper attachment portion and the lower attachment portion of the engine cradle.Type: GrantFiled: October 31, 2018Date of Patent: February 2, 2021Assignees: Nissan North America, Inc., NISSAN MOTOR CO., LTD.Inventors: Stephen Fekete, Ryan Corby, Adam Strean, Takahiro Watanabe, Yunosuke Yamada, Musashi Kishida

Patent number: 7771137Abstract: A connecting structure includes a hollow member or a half hollow member including two side portions opposed apart to each other; a collar; and a bolt. The collar includes two contact surfaces at both ends of the collar. The two contact surfaces are adapted to respectively abut on the two side portions between the two side portions. At least one of the two contact surfaces is formed with a receiving portion for caulking. Moreover, the collar is formed with a bolt-hole passing through the two contact surfaces. The collar is disposed between the two side portions, and is caulked with the hollow member or half hollow member at a caulked portion formed from at least one of the two side portions toward the receiving portion. The bolt is adapted to pass through the two side portions and the bolt-hole to connect the hollow member or half hollow member with another member.Type: GrantFiled: June 13, 2006Date of Patent: August 10, 2010Assignees: Nissan Motor Co., Ltd., Nippon Light Metal Company, Ltd.Inventors: Eiji Anzai, Yunosuke Yamada, Yoshihiro Konno, Yuki Murayama
