The utility model discloses a crank-free pedal and relates to a bicycle pedal. The transmission efficiency of the crank type pedal to the pedaling force is only more than 60%, and the transmission efficiency of a new project reaches 100%. The crank-free pedal is a green project. The project is divided into: a middle shaft chain disc part (1), a pedal driving part (2), and casing parts (3A, 3B, 3C). The middle shaft chain disc part comprises a middle shaft assembly (11) and a chain tensioner (14) which are fixed with the shell (3A). The middle shaft assembly and the half shafts (17 and 18) are connected through a flywheel seat (19). Flywheels (29, 30) are fixed by the flywheel seat. A chain plate (21) is fixed on the half shaft (17) and is connected with a rear wheel flywheel through a chain. According to the pedal driving part, an idle wheel (32c) and a reversing chain wheel assembly (33) are fixed to a machine shell (3B). The idle wheels (32c, 32d) are dragged by chains (31a, 31b). A chain (31a,) is connected to the flywheel. The chain (31b) is connected with the left pedal and the right pedal. The sliding rod (34) is fixed on the shell flange (9). The sliding rod is matched with a sliding block (35). The two linear bearings (37) and a vertical handle (38) of the pedal are fixed by the sliding block seat plate (36). The vertical handle is connected with a swinging pedal handle (39). The swing handle is provided with a pedal shaft fixing hole (40). A chain pulling and fixing mechanism (41) is arranged on the other surface of the seat plate. According to the principle, pedals are treaded, a sliding block traction chain (31a) slides downwards, a middle shaft flywheel is pulled to drive a chain disc to rotate, and a chain disc traction chain pulls a flywheel of a rear wheel to rotate.

    无曲柄脚蹬,涉及自行车脚蹬。曲柄式脚蹬对踏力传输效率只有60%多,新项目传输效率达100%。是绿色项目。项目分:中轴链盘部份(1);脚踏驱动部份(2);机壳部分(3A,3B,3C)。中轴链盘部分:中轴总成(11),链条涨紧器(14),与机壳(3A)固定。中轴总成,半轴(17,18)用飞轮座(19)连体。飞轮座固定飞轮(29,30)。半轴(17)固有链盘(21),链盘用链连接后车轮飞轮。脚踏驱动部份:惰轮(32c)换向链轮总成(33)与机壳(3B)固定。惰轮(32c,32d)拖有链条(31a,31b)。链条(31a,)与飞轮连接。链条(31b)连接左右脚踏。滑杆(34)固定在机壳法兰(9)上。滑杆配合滑块(35)。滑块座板(36)固定两个直线轴承(37)与脚踏的竖柄(38)。竖柄连接摆动踏柄(39)。摆柄设有脚踏轴固定孔(40)。座板另面设有链的牵固机构(41)。原理,踏压脚踏,滑块牵链(31a)下滑,牵动中轴飞轮带动链盘转动,链盘拖链牵动后车轮的飞轮转动。
