摘要

The vehicle has an aluminum frame comprising three independent arms supporting wheels e.g. front wheel (2), rear wheel (4) and middle wheel (3), arranged on a line. The front wheel is maintained in a position by a double longeron fixed at an end on a free hub and another end on a longeron carried by a support of an engine block (6). A middle wheel is elastically subjugated with the double longeron. A face of the longeron is carried by the support of the engine block. The rear wheel is moved in auto direction to free castor angle.
