Description
Technical field
The utility model relates to a kind of bicycle drive, belongs to bicycle drive technology field.
Background technology
Bicycle is a kind of very common very convenient vehicle again, and people often use it when on and off duty and outing, and cycle racing is the motion of a low-carbon (LC), environmental protection, convenient, safety, body-building.Thereby existing bicycle is all positive dirction makes bicycle to overtake to pedal, yet long-time forward is ridden to pedal and is easily caused that shank aches, if the incorrect meeting of posture causes that bicyclist is to inhomogeneous naked joint and the knee joint generation pain of causing of force distribution by bike simultaneously, if amount of exercise is crossed conference and caused fatigue and aching pain in waist and back in the process of riding, thereby harm people's is healthy.
Utility model content
The purpose of this utility model is cannot realize to pedal bicycle by reversing sense and advance forward in order to solve existing bicycle, and then a kind of bicycle drive is provided.
The technical solution of the utility model:
A kind of bicycle drive comprises sprocket wheel and axis, sprocket wheel is arranged on axis by forward free-wheel clutch, described bicycle drive also comprises the first transmission gear, the second transmission gear, the second driving chain wheel, the first driving chain wheel, rotating shaft and oppositely free-wheel clutch, described the first transmission gear is fixedly mounted on sprocket wheel, rotating shaft is arranged on vehicle frame, before and after described axis and rotating shaft, be arranged in parallel, the second transmission gear is installed in rotating shaft, the second transmission gear and the engagement of the first transmission gear, the second driving chain wheel is also installed in rotating shaft, the first driving chain wheel is arranged on axis by reverse free-wheel clutch, the first driving chain wheel is installed and is connected by chain with the second driving chain wheel.
Preferred: between the first described transmission gear and sprocket wheel, by axle sleeve, to be fixedly connected with.Dismounting while being convenient to keep in repair and installation are so set.
Preferred: the first described transmission gear and the transmitting ratio of the second transmission gear are 1:1.So arrange, the speed that in the time of can rationally controlling reversing sense treadmill, bicycle is advanced forward, avoids reverse treadmill bicycle running speed and forward treadmill bicycle running speed to change causing bicycle to topple over.
Preferred: the first described transmission gear and the first driving chain wheel, the installing space of the second transmission gear and the second driving chain wheel is at 10mm～150mm.So arrange, can guarantee the installation strength of bicycle drive, avoid carrying out forward and reversely causing that bicycle damages to pedal time.
The utlity model has following beneficial effect: the utility model changes the single mode of riding; by positive dirction to pedal with reversing sense to pedal alternately used impel bicycle to overtake; changed the unicity of cycle racing; the forward and reverse whole body that alternately can make to pedal of on the go loosens, and can stimulate not the often muscle of activity, promotes the circulation of blood; balance function of human body; prevention aging of brain, the agility of raising system, improves cardio-pulmonary function.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model;
Fig. 2 is front view of the present utility model;
1-sprocket wheel in figure, 2-the first transmission gear, 3-the second transmission gear, 4-the second driving chain wheel, 5-the first driving chain wheel, 6-axis, 7-rotating shaft, 8-axle sleeve, the reverse free-wheel clutch of 9-, 10-forward free-wheel clutch, 11-chain.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, a kind of bicycle drive of present embodiment comprises sprocket wheel 1 and axis 6, sprocket wheel 1 is arranged on axis 6 by forward free-wheel clutch 10, described bicycle drive also comprises the first transmission gear 2, the second transmission gear 3, the second driving chain wheel 4, the first driving chain wheel 5, rotating shaft 7 and oppositely free-wheel clutch 9, described the first transmission gear 2 is fixedly mounted on sprocket wheel 1, rotating shaft 7 is arranged on vehicle frame, described axis 6 be arranged in parallel with rotating shaft 7 front and back, the second transmission gear 3 is installed in rotating shaft 7, the second transmission gear 3 and the first transmission gear 2 engagements, the second driving chain wheel 4 is also installed in rotating shaft 7, the first driving chain wheel 5 is arranged on axis 6 by reverse free-wheel clutch 9, the first driving chain wheel 5 is installed and is connected by chain 11 with the second driving chain wheel 4, between the first described transmission gear 2 and sprocket wheel 1, by axle sleeve 8, be fixedly connected with, the first described transmission gear 2 and the transmitting ratio of the second transmission gear 3 are 1:1, the installing space of the first described transmission gear 2 and the first driving chain wheel 5, the second transmission gears 3 and the second driving chain wheel 4 is at 10mm～150mm.
When bicyclist's forward is to pedal time, after sprocket wheel 1 drives bicycle, power wheel is rotated in the forward, bicycle forward travel; When bicyclist's reversing sense is to pedal time, axis 6 drives the first driving chain wheel 5 opposite spins by reverse free-wheel clutch 9, the first driving chain wheel 5 drives the second driving chain wheel 4 opposite spins by chain 11, the second driving chain wheel 4 drives rotating shaft 7 opposite spins, thereby drive the second transmission gear 3 opposite spins, the second transmission gear 3 and the first transmission gear 2 engagements, rotated by effect first transmission gear 2 positive dirctions of the second transmission gear 3, thereby the 1 positive dirction rotation of band movable sprocket, and then realize bicycle forward travel.
Present embodiment is the exemplary illustration to this patent just, does not limit its protection domain, and those skilled in the art can also change its part, as long as no the Spirit Essence that exceeds this patent, all in the protection domain of this patent.
