Patent number: 10688843Abstract: A torsion beam of a vehicle torsion beam suspension has a closed cross section. A beam center portion has an inverse substantially v-shaped cross section or a substantially v-shaped cross section. Circumference increasing portions having a longer circumferential length toward the beam ends are disposed at opposite sides of the beam center portion. Each circumference increasing portion has a beam width that is a width in the fore and aft direction of a vehicle body, the beam width gradually increasing toward a beam end, and increasing at a higher rate as a position of the beam width is closer to the beam end.Type: GrantFiled: June 29, 2018Date of Patent: June 23, 2020Assignees: Y-TEC CORPORATION, MAZDA MOTOR CORPORATIONInventors: Kazuhiro Nishimura, Masayuki Jobira, Hiroyuki Takahashi, Hideaki Kawaguchi, Nobuyuki Nakado, Shun Kuwako

Patent number: 10611410Abstract: The present application discloses front chassis structure including set plate to which impact absorber is connected. Front chassis structure includes: pillar member having inner support plate portion for supporting impact absorber, outer support plate portion for supporting impact absorber in cooperation with inner support portion, and pillar portion having horizontal cross-section bulging rearward from inner and outer support plate portions; connection member for connecting pillar portion to vehicle body; front side member extending rearward from pillar member; and projecting member projecting outward from pillar member. Set plate is mounted on the outer and inner support plate portions. Projecting member includes front end covered by outer support plate portion. Projecting member is connected to front side member so that projecting member presses front side member inward under moment around connection member, moment being generated at collision of automobile.Type: GrantFiled: February 27, 2018Date of Patent: April 7, 2020Assignees: Y-TEC CORPORATION, MAZDA MOTOR CORPORATIONInventors: Tomohisa Daikokuya, Yasunari Jinbo, Katsuyuki Komiya, Yoko Takanashi
