The device is characterized in that the driving wire cable is connected with the roller sliding block, the one-way driving pulleys and the deflecting pulley so as to form a linear reciprocating drive mechanism; and the driving sleeve shaft is connected with the left and right groups of one-way driving pulleys and the driving sprocket so as to realize the time sharing one-way transmission matching of two pedals. The device has the benefits that the pedaling riding efficiency can be effectively improved by more than 30 percent, the fatigue of two legs can be effectively reduced, the space height of the pedal device during vertical movement is greatly reduced, the disadvantages of a rotating pedaling lie riding bicycle is overcome, and powerful technical support is provided for adding an air guide casing onto the lie riding bicycle.
Description
Technical field
The utility model relates to a kind of foot pedal apparatus of bicycle, relates in particular to a kind of front and back reciprocating pedal device by bike of lying that uses the unidirectional driven pulley transmission of two groups matching technique.
Background technology
Lying is the improved type of standard bicycle by bike, is provided with sweptback chair, and the rotary pedals device is also changed to the bicycle front portion from traditional position, middle and lower part.The posture of cyclist partly to lie, both feet are stretched to the place ahead and are scrunched and ride, have comfortable, easily, protection lumbar vertebrae, the characteristics of protection wrist.
Lie when riding by bike, cyclist's both feet are ridden by the original rotation that scrunches up and down, become to front and back scrunch rotation and ride.The shortcoming of this mode of riding is, the cyclist need not stop praises both feet, but the motion of vertical direction is not done useful work to advancing of bicycle, thereby increases the weight of physical load; The crank length of rotary pedals device is generally at 170 millimeters, the vertical amplitude of oscillation of both feet reaches 340 millimeters, add about 300 millimeters of people's foot length, add minimum ground clearance 80mm, the vertical running space height of rotary pedals device is at least at 720mm, because the cyclist partly lies, eye locations reduces, the sight line that this will influence the cyclist influences traffic safety; The rotating operation mode of rotary pedals device makes that effectively the stroke of acting shortens greatly, approximately has only 50% of pedal stroke, wherein also has the foot-operated power of quite a few not waste owing to the anglec of rotation is good.
An important development direction of lying by bike installs the air conducting shell exactly additional, to reduce the resistance of wind.The vertical running space height that installs water conservancy diversion shell requirement foot pedal apparatus additional is low more good more.
Summary of the invention
The purpose of this utility model provides the unidirectional driven pulley transmission of the two groups of a kind of utilization matching technique, linear reciprocation sliding technology, by bike the front and back reciprocating pedal device of realizing lying.
The technical scheme that its technical matters that solves the utility model adopts is, this foot pedal apparatus comprises the linear reciprocation transmission device, two groups of unidirectional driven pulleies transmission coupling mechanisms, the synchronous device of left and right sides linear reciprocation transmission device.
Slideway of the present utility model, the roller slide block, stretcher and unidirectional driven pulley, two cover linear reciprocation transmission devices about connecting to form via driving wire rope, accept the reciprocal power that scrunches before and after cyclist's both feet, and be transferred to the unidirectional driven pulley transmission of two groups coupling mechanism.
Drive sprocket of the present utility model with about two groups of unidirectional driven pulleies be connected with the transmission sleeve, form the unidirectional driven pulley transmission of two groups coupling mechanism, two cover linear reciprocation transmission devices import into about acceptance scrunches power, and drives drive sprocket and transmit propulsive effort to cycle wheel.Unidirectional driven pulley has been eliminated the reverse drive influence when stretcher retreats, the transmission coupling of two cover linear reciprocation transmission devices about realization.
Synchronous steel cable of the present utility model is via synchronous roller, and two roller slide blocks about connection are formed the synchronous device of left and right sides linear reciprocation slide mechanism.When the roller slide block of a certain side is stressed when sliding forward, synchronously steel cable automatically with the roller slide block of opposite side to rear haulage, auxiliary cyclist finishes and receives foot-propelled and do.
The beneficial effects of the utility model are, can effectively improve to scrunch and ride efficient more than 30%, effectively alleviate both legs fatigue, reduce the vertical running space height of foot pedal apparatus greatly, overcome lie by bike inherent defect of rotary pedals, and, provide powerful technical support for lying by bike to installing the development of air conducting shell additional.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structure side view of the present utility model.
Fig. 2 is a structure top view of the present utility model.
Among the figure: 1, slideway, 2, the roller slide block, 3, stretcher, 4, roller synchronously, 5, drive sprocket, 6, unidirectional driven pulley, 7, the transmission sleeve, 8, driving wire rope, 9, steel cable synchronously, 10, deflection sheave.
The specific embodiment
As shown in Figure 2, unidirectional driven pulley 6 of the present utility model is fixed on the transmission sleeve 7, and drive sprocket 5 is fixed on the transmission sleeve 7; Stretcher 3 is fixed on the roller slide block 2; Roller slide block 2 is nested in the chute of slideway 1.Driving wire rope 8 (see figure 1)s are captiveed joint with roller slide block 2.Owing to be that both feet scrunch, slideway 1, roller slide block 2, stretcher 3, unidirectional driven pulley 6, driving wire rope 8, deflection sheave 10 all be about each one.
As shown in Figure 1, roller slide block 2 of the present utility model connects driving wire rope 8, and driving wire rope 8 connects deflection sheave 10, connects unidirectional driven pulley 6, connects roller slide block 2 again, forms the closed link that drives.Roller slide block 2 of the present utility model connects synchronous steel cable 9, and steel cable 9 connects synchronous roller 4 synchronously, connects roller slide block 2 again, forms closed synchronization link.
Further specify below in conjunction with Fig. 1, Fig. 2.
When the pedal power that is subjected to the cyclist when the stretcher 3 of a certain side drove roller slide block 2 and slides forward, roller slide block 2 drove driving wire ropes 8 and affects unidirectional driven pulley 6 to be rotated in the forward; Driven pulley 6 is when being rotated in the forward, and the in-to-in power-transfer clutch is in locking states, drives transmission sleeve 7 rotation in the same way; Transmission sleeve 7 drives drive sprocket 5 rotations, advances thereby drive bicycle.
When above-mentioned a certain side wheel slide block 2 slided forward, roller slide block 2 drove synchronous steel cable 9 simultaneously, affected the roller slide block 2 of opposite side to slide backward; The roller slide block 2 of opposite side drives driving wire rope 8 and affects unidirectional driven pulley 6 contrarotations; Driven pulley 6 is when contrarotation, and the in-to-in power-transfer clutch is in released state, can not drive 7 rotations of transmission sleeve, thereby has realized the timesharing unidirectional transmission coupling that both feet scrunch.
Driving wire rope 8 can be used the cycle chain transmission instead, as long as simultaneously unidirectional driven pulley 7 is changed into unidirectional the tooth flywheel is arranged, and deflection sheave 10 changes into there being the tooth pulley to get final product.
