Abstract: An electric vehicle structure includes a drive system, a front lateral member and a rear upper lateral member. The front and rear lateral members are elongated in a lateral direction of a vehicle and spaced apart from each other in a forward-rearward direction of the vehicle with the drive system interposed therebetween. The vehicle structure further includes a rear lower lateral member elongated in the lateral direction of the vehicle and disposed beneath a motor of the drive system.

Abstract: A suspension arm jointing device for a vehicle includes a steering axis and a roll center can be independently controlled. By dualizing a joint between a lower arm and a knuckle into a rotation portion based on wheel steering and a rotation portion based on wheel's up/down movement, a lower aim joint's function for determining a roll center height during turning and determination of an steering axis position which affects wheel vibration and braking stability during linear driving can be controlled independently of each other, thereby heightening the roll center and determining an optimal steering axis (kingpin axis) position.
