Patent number: 9789743Abstract: A vehicle suspension structure includes a suspension arm and a ball joint. The suspension arm is connected between a suspension member and a vehicle-widthwise outer side end connected to a vehicle wheel. The ball joint connects the suspension arm and the vehicle wheel. When the vehicle receives an impact in the longitudinal direction, a socket of the ball joint pivots relative to a ball as the suspension arm deforms, and a flange portion on an open side of the socket interferes with a stud shaft of the ball joint. The interference causes the flange portion to deform and the ball to come out of the socket to undo the link with the vehicle wheel by the ball joint. Upon becoming unlinked, the vehicle wheel moves toward the vehicle-widthwise outer side and interference with the rear vehicle body is suppressed to limit deformation of the vehicle body.Type: GrantFiled: April 11, 2014Date of Patent: October 17, 2017Assignee: Nissan Motor Co., LtdInventors: Shingo Donkai, Akira Yamaguchi, Tomoyuki Nakao, Yoshihiro Konno, Kuniaki Ozono, Naoki Shimizu
