Up-and-down reciprocating type bicycle and rickshaw transmission mechanism

Abstract

The invention discloses an up-and-down reciprocating type bicycle and rickshaw transmission mechanism which comprises two sets of flywheels, ratchet mechanisms are arranged in the flywheels, the two flywheels are installed on the two sides of a rear wheel respectively, the rear wheel is installed on a rear wheel shaft, and transmission structures are installed on the two sets of flywheels respectively; and a frame, wherein four sets of fixed pulleys are installed in the middle of the frame, and a set of fixed pulleys installed on the front face of a vertical stand column of the frame is sleeved with a linkage rope. According to the up-and-down reciprocating type bicycle and rickshaw transmission mechanism, rope transmission or standard bicycle chain transmission is adopted, in the driving process, each pedal only reciprocates on a section of arc, the movement range is just most suitable for human body power generation, power generation and work application can be performed through the self gravity of a rider. The defects that when a traditional bicycle runs, a moment arm is zero, and a dead point does too much idle work are overcome, and riding is more labor-saving.

Description

technical field [0001] The invention relates to the field of bicycles and rickshaws, in particular to an up and down reciprocating transmission mechanism for bicycles and rickshaws. Background technique [0002] The transmission systems of existing bicycles and rickshaws mostly use circular-running chain transmissions, and the chains are near the trousers corners, and the trousers feet are often stained with a lot of oil. [0003] In existing bicycles, the force is exerted by the feet during riding, and the crank rotates in circles. The force exerted by the feet is basically vertically downward, so the torque goes from zero to maximum and then to zero. The force exerted by the human body has done a lot of useless work, and the rider will consume a lot of physical strength when riding, resulting in the comfort range of ordinary people riding an ordinary non-variable bicycle can only be within a short distance of two or three kilometers. The range of motion is large, and peop...

[0003] In existing bicycles, the force is exerted by the feet during riding, and the crank rotates in circles. The force exerted by the feet is basically vertically downward, so the torque goes from zero to maximum and then to zero. The force exerted by the human body has done a lot of useless work, and the rider will consume a lot of physical strength when riding, resulting in the comfort range of ordinary people riding an ordinary non-variable bicycle can only be within a short distance of two or three kilometers. The range of motion is large, and people with slightly better physical strength will feel soreness and discomfort in the knee joints when they use a derailleur for about ten kilometers. It is difficult for ordinary people to ride long distances; most of the current bicycles can only use The way of riding, in order to make the upper body lean forward, maintaining this riding posture for a long time will easily cause local tenderness and discomfort of the rider's buttock muscles, and also affect the rider's willingness to ride
