The invention provides a bicycle rope transmission mechanism. The bicycle rope transmission mechanism comprises a double-ratchet-wheel rear wheel, flywheels, a transmission rope, a rack, fixed pulleys, a connecting rods, pedals, a linkage rope, a rear wheel shaft and a volute spiral spring. The two flywheels are installed on the two sides of the double-ratchet-wheel rear wheel, and one end of the transmission rope is fixed to the flywheels, wound on the flywheels for a plurality of circles, then wound around the fixed pulleys installed on the rack and connected with the corresponding connecting rods. A connecting rod mounting shaft can be independently mounted on the rack, and the rear wheel shaft can also be used. The front ends of the two connecting rods are wound around the fixed pulleys installed on the rack through the linkage rope to be connected together, and pedal linkage is guaranteed. One end of the spiral spring is installed on the rear wheel shaft, and the other end is installed on the flywheels to achieve winding recovery of the transmission rope. 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 the 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.
本发明提供了一种自行车绳索传动机构,包括双棘轮后车轮,飞轮,传动绳索,机架,定滑轮,连杆,脚踏,联动绳索,后轮轴和涡卷弹簧;两个飞轮安装在双棘轮后车轮的两侧,传动绳索一端固定在飞轮上,在飞轮上缠绕数圈后绕过安装在机架上的定滑轮,与相对应的连杆连接。连杆安装轴可在机架上单独安装,也可使用后轮轴。两个连杆前端用联动绳索绕过安装在机架上的定滑轮,连接在一起,保证脚踏联动。涡卷弹簧一端装在后轮轴上,一端安装在飞轮上,实现传动绳索缠绕回复。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。
