低跨式摩托车的结构设计及发展

Structure Design and Development of Motorcycle with lower side car

低跨式摩托车主要用于邮政、商务、送货等业务,经济实用、使用维修方便,一直是畅销车型;低跨式摩托车的燃油经济性最低,比一般车可低10％～20％;由于车体中部低凹,座高度较小,使整车质心很低、使行驶稳定性好和制动力也完全;低跨式摩托车采用双伸缩简式前叉.即提高了前叉的刚度又从结构设计上提高了低跨式摩托车的高速操纵稳定性。

The said motorcycle is mostly used for postal service .commercial service and goods-delivery,and well sold for its economy and ease-maintenance. The fuel economy is 10%~20% lower than that of other motorcycles. Its lower centre of gravity, good handle-stability and perfect braking behavior come from the lower central body and lower seat. The motorcycle is equipped with double-telescopic front fork, which increases the rigidness of front fork and the high-speed handle stability.
