A kind of double transverse arm suspending frame guiding mechanism and steering mechanism that employed in outer rotor typed hub motor has been put forward, which could make the four wheel driven electric car to realize a rotation round arbitrary point and to translate along arbitrary direction. The technique of fixing a breakdown when the motor is out of order has been studied, that is by means of the on-off combination of an electronic clutch to drive a steering motor letting the four wheels be all reset and the mechanism could still be able to maintain its steering ability. The posture of suspending frame guiding mechanism was described with Euler angle, and the posture angle formulae of suspending frame guiding mechanism relevant to location parameters of car wheels were derived. Parameterization was carried out upon coordinate of each controlling point. The parameterized model was established under ADAMS software and optimization design was carried out upon the suspension frame guiding mechanism.
