Description
Technical Field
The invention relates to the field of transportation tools, in particular to a pedal bicycle.
Background
The power conversion transmission mechanism of the traditional pedal bicycle comprises a middle shaft assembly, a crank assembly, a rear wheel shaft assembly, a driving chain disc, a chain and a driven chain wheel assembly; the power of the bicycle is from the continuous circular motion of the two legs of a human body, drives the left crank, the right crank and the driving chain disc to rotate continuously for 360 degrees, and the power is transmitted to the driven chain wheel and finally to the rear wheel shaft from the driving chain disc through the chain, so that the bicycle can move forwards.
The traditional pedal bicycle has poor driving performance and is hard to ride, is mainly related to a driving mode, is limited by the movement distance of legs of a human body and the minimum ground clearance of pedals, and the design length of a crank of the pedal bicycle can be limited within a small range. The circumferential driving mode of the crank and the driving chain disc ensures that the height difference of two legs of a rider is large and the high-efficiency driving angle is small. In the 360-degree rotation process of the crank, the problem of an upper dead point and a lower dead point exists, so that the utilization rate of an effective force arm is insufficient, the reset stroke of the crank is large, the optimal force application angle is difficult to master, and the power of a human body is difficult to fully play a role; meanwhile, the crank rotates in a whole circle, and the length of the crank is limited by the distance from the rotating shaft center to the ground or the telescopic length of the leg of a user, so that the conventional pedal bicycle is heavy in operation and large in physical consumption.
The existing pedal bicycles with different driving modes have the advantages that a crank does not rotate for a whole circle, reciprocating driving is carried out in a certain angle, and specifically, the length of a pedal used for driving is increased, so that conditions are provided for the lengthening of a driving force arm. The length of the pedal plate is a solid concept, the length of the force arm is a physical quantity related to the force application direction, and the length of the right-angle side corresponding to the acute angle of the included angle between the pedal plate and the force application direction is the length of the pedal plate. For example, the mechanism is provided with a force arm, the rotating shaft center of the force arm is near the rear wheel shaft, the force arm is longer, and the mechanism is driven in a reciprocating manner within a certain angle; the driving force arm drives the resistance arm, the resistance arm drives the eccentric wheel to rotate through the connecting rod, the eccentric wheel and the rear wheel are coaxially fixed, so that the rear wheel is driven, and the length of the force arm can be periodically changed as long as the eccentric wheel rotates for a whole circle or the crank rotates for a whole circle in the driving device. Assuming that the force application direction and the force application magnitude of the leg of the person are always determined to be unchanged, in this case, the change curve of the length of the moment arm is a sine-cosine curve, according to the riding experience, the practical situation is that the force application magnitude of the leg is related to the physical strength, but the force application direction has a small interval change, mainly near the position where the leg can be stretched most, so that the above assumptions are qualitatively valuable for research and analysis, then the following can be obtained: the manual driving traffic equipment has the advantages that the output curve of force can have wave troughs and wave crests, the highest point of the wave crests corresponds to the moment when the moment arm is equal to the length of the crank, the phase periods occupied by the wave troughs and the wave crests are the same, and the driving efficiency is the same as that of a traditional bicycle. Although the length of the force application arm of the reciprocating motion mechanism is not limited by the distance between the rotating shaft center and the ground, but is limited by the telescopic distance of the leg, the actual force arm is the length of the driving force arm minus the resistance arm, and the shorter the actual force arm is, the more the effort is.
There is now a further market-entry bicycle, marketed by Chongqing Chi Bibikes, called Arbitrary rides, patent CN201210036555.2, the starting point is that both positive and negative treading can be realized, although the one-way bearing in the one-way overrunning clutch is used at the first stage position of the driving force arm during the specific implementation, the advantage that the driving angle can be adjusted freely by the one-way bearing is exerted, the resistance arm is the radius of the one-way bearing and is far less than the length of the power arm, but the resistance arm is the same as the riding mode of the traditional bicycle, the power arm still rotates a whole circle as the crank of the traditional bicycle, the length is naturally limited by the distance between the axis and the ground, in order to apply force at any angle on the legs of people, no force arm limiting device is arranged, the defect that the actual moment arm length is rapidly smaller than the crank length is generated when the leg stretching amount is larger than the crank length; and the arm of force can be rotated to complete a circle and can not hit the ground, so that the structural defect is as follows: the length of the pedal plate is far longer than the distance from the axle center of the pedal plate to the ground after adopting the one-way bearing, so that the favorable conditions of the power arm and the actual driving power arm are increased; in addition, in order to realize that the pedal can be driven by forward and backward pedaling, a gap bridge gear is additionally arranged between the left crank and the right crank to enable the left driving arm and the right driving arm to be related, and the defect that independent and simultaneous dual driving of the left driving arm and the right driving arm cannot be realized is realized. Although the bicycle can be pedaled in both the front and the back, or the included angle of a left crank and a right crank is initially set to be less than 180 degrees, the output curve of the driving force can be converted into the wave crest of the traditional bicycle even if the bicycle is pedaled in the same direction alternatively, but the initial setting is hard, so that a rider cannot independently and effectively select the wave crest section of the driving force output independently in the actual riding process; in addition, due to the blocking of the intermediate gear added between the left crank and the right crank, the installation position of the whole device is limited, for example, a middle shaft, namely a driving chain disc shaft, cannot be coaxial with a rear wheel, namely a driving wheel, so that the extremely simplified design of the whole vehicle cannot be realized, and particularly, the longer favorable condition of realizing a driving arm is wasted; in addition, the reverse gear clutch device is not provided, and the components of the transmission system are easily damaged when the reverse wheel force is too large.
