The invention provides a reciprocating type bicycle and rickshaw transmission mechanism. The reciprocating type bicycle and rickshaw transmission mechanism comprises a double-ratchet-wheel rear wheel, flywheels, a transmission chain (transmission rope), a rack, a fixed pulley, connecting rods, pedals, a linkage rope and a rear wheel shaft. The two flywheels are installed on the two sides of the double-ratchet-wheel rear wheel, the transmission chain (transmission rope) is of a sectional type, and the rear section has large elasticity. The elastic end of the transmission chain (transmission rope) is fixed on the rack or at the front end of the connecting rod, passes through the flywheel and the fixed pulley, and is finally connected with the corresponding connecting rod; the connecting rod can be mounted on a frame and can also be mounted on a rear wheel shaft; the front ends of the two connecting rods are connected together by winding the fixed pulley on the rack through a linkage rope; and pedals are arranged at the front ends of connecting rod arms. Circumferential motion is replaced by up-down reciprocating motion during riding, work can be done by means of the gravity of a human body, the force exerting function of a human body structure is exerted to the maximum extent, the comfort of a rider is improved, the number of parts is small, machining and maintenance are easy, and large-scale popularization is easy.
本发明提供了一种往复式自行车、人力车传动机构,包括双棘轮后车轮,飞轮,传动链(传动绳索),机架,定滑轮,连杆,脚踏,联动绳索和后轮轴;两个飞轮安装在双棘轮后车轮的两侧,传动链(传动绳索)为分段式,后一段具有较大的弹性;传动链(传动绳索)弹性一端固定在机架上或连杆前端,然后经过飞轮、定滑轮,最后分别与相对应的连杆连接;连杆安装可在机架上设计轴,也可使用后轮轴;两个连杆前端用联动绳索绕过机架上的定滑轮,连接在一起;连杆臂前端装有脚踏。本发明使得骑行以上、下往复运动取代圆周运动,能借助人体自身的重力做功,最大限度的发挥人体结构的用力功能,改善骑者舒适性,本发明部件数量少,易加工维护,易于大范围推广。
