The pedal motorcycle frame structure specifically comprises a front fork vertical pipe, a main beam arranged on the lower side of the front fork vertical pipe, a right bent pipe, a left bent pipe and a reinforcing plate arranged at the bent position of the main beam, the right bent pipe and the left bent pipe are symmetrically arranged on the two sides of the tail of the main beam, and the tail of the right bent pipe and the tail of the left bent pipe are in closed-loop connection through a first reinforcing round pipe; the improvement of the invention is as follows: the device also comprises a left auxiliary beam and a right auxiliary beam which are symmetrically arranged on the two sides of the main beam; the interiors of the left auxiliary beam and the right auxiliary beam are of hollow structures, and balancing weights capable of adjusting the balance weight proportion of a vehicle body are arranged in the left auxiliary beam and the right auxiliary beam. Under the condition that the appearance structure of the frame main body is kept unchanged, the front and rear counterweight proportion of the whole motorcycle is adjusted by changing the size and weight of the counterweight block, so that the loads of the front and rear wheels of the pedal motorcycle reach the optimal counterweight proportion, and the stability, the safety and the reliability of the pedal motorcycle in the running process are improved; and meanwhile, the universality of the frame is improved, and the development cost of the frame is reduced.

    本发明提出了一种踏板摩托车车架结构,具体包括前叉立管、设于前叉立管下侧的主梁、对称设于主梁尾部两侧的右弯管和左弯管、设于主梁弯折处的加强板,右弯管和左弯管的尾部通过第一加强圆管成闭环连接;本发明的改进之处在于:还包括对称设于主梁两侧的左辅梁和右辅梁;左辅梁和右辅梁的内部为中空结构,且左辅梁和右辅梁内设有能够调整车身配重比例的配重块;本发明在保持车架主体外观结构不变的情况下,通过改变配重块的尺寸、重量来调节整车的前后配重比例,从而使踏板摩托车前后轮荷载达到最佳配重比例,增加踏板摩托车在行驶过程中的稳定性、安全性、可靠性;同时,也提升了车架的通用性,降低了车架的开发成本。
