The existing bicycle is powered by feet during riding, the crank runs around, the moment goes from zero to the maximum and then goes to zero, and the bicycle continuously reciprocates, in the process, as the moment arm does not change in sections, a human body applies force to do a lot of useless work, in addition, the transmission efficiency of chain transmission is slightly low, the rider can consume more physical power during long-distance riding, the comfortable range of the common non-variable speed bicycle ridden by common people can only be within two kilometers and three kilometers in a short distance, the existing bicycle runs around the crank, the activity range of the knee joint is large, people with slightly good physical power can feel the soreness and the discomfort of the knee joint even if the variable speed bicycle is used within ten kilometers, and the bicycle is difficult to be suitable for common people to.
Therefore, a new bicycle transmission mechanism needs to be designed to solve the problems in the prior art.
Disclosure of Invention
In order to overcome the above disadvantages of the prior bicycle through chain transmission, the utility model provides a bicycle rope transmission mechanism. The bicycle transmission mechanism adopts rope transmission, has good stability, compact structure, uniform stress and quiet running, and realizes speed change by changing the connecting position of the rope on the pedal connecting rod. In the driving process, each pedal connecting rod only reciprocates on a section of circular arc, and the movement range is just the range which is most suitable for a human body to exert force and has the best force application effect; compared with the traditional chain transmission structure, the bicycle can utilize the self gravity of a rider to apply force and do work, and overcomes the defect that the traditional bicycle has zero force arm and dead points to do excessive useless work in the operation process; in addition, the movement track of the pedal only relates to the front part of the mounting shaft, the mounting shaft can be shared with a rear wheel shaft, the rear wheel shaft can be omitted, two half shafts are independently mounted on two sides of the frame, and the bicycle moves backwards a lot relative to a rotating shaft of a transmission bicycle, so that the limitation on the frame body and the whole layout of the bicycle is small, the distance between the front wheel and the rear wheel can be reduced, and the whole structure of the bicycle is compact and small. The utility model discloses the rope is used in the transmission, need not lubricated like the chain drive.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a bicycle rope transmission mechanism comprises a double-ratchet rear wheel, a flywheel, a transmission rope, a frame, a fixed pulley, a connecting rod, a pedal, a linkage rope, a rear wheel shaft and a volute spiral spring; two flywheels are arranged on two sides of the double-ratchet wheel rear wheel, one end of a transmission rope is fixed on the flywheels, then the transmission rope winds a plurality of circles on the flywheels, then winds a fixed pulley arranged on the rack, and finally is respectively connected with corresponding connecting rods. For better practical effect and reduction of production cost, it is suggested to use the rear wheel axle as the rotation axis of the connecting rod.
Furthermore, a mandrel is arranged at the lower part of the frame, a fixed pulley is arranged on the mandrel, and plastic bearings similar to those of the easily-checked bearing are suggested to be arranged between the mandrel and the seat hole and between the connecting rod and the shaft, so that the frame is light in weight, free of lubrication, compact in structure and relatively environment-friendly.
Furthermore, a pedal is installed at the front end of the connecting rod, a plurality of rope connecting positions are arranged on the connecting rod or the rope connecting positions are designed to be adjustable along the length direction of the connecting rod, the length of the force arm can be changed through different rope connecting positions, speed change is achieved, and the bicycle is suitable for different road conditions such as ascending and descending. The lever arms at the front ends of the two connecting rods are connected together by a linkage rope bypassing the fixed pulley arranged on the rack, and have the functions of pedal limiting and pedal linkage ensuring.
Further, the volute spiral spring has one end mounted on the rear wheel shaft and the other end mounted on the inner wall of the flywheel, and is relatively low in rigidity and provides restoring force so that the corresponding transmission rope is wound on the flywheel again when the pedal moves upward.
The utility model discloses part is small in quantity, reasonable in design, and overall structure is simple, low cost, and the workable maintenance, the reliability is high, long service life, and power transmission is smooth-going, quiet, and is efficient, easily promotes on a large scale. The pedal plate moves up and down in a reciprocating way to replace circular motion, so that the pedal plate is more in line with the physiological structure of the human body and can do work by means of the gravity of the human body.
