Description
The utility model relates to a kind of bicycle, and it is specially adapted to the bicycle with f-w-d.
Existing bicycle all is by back-wheel drive, when running into when need quickening fast by bike, or way far away, against the wind, during situation such as upward slope, only firmly by lower limb, driving the trailing wheel of bicycle, speed is required great effort slowly and relatively by bike.
The purpose of this utility model provides a kind of bicycle with f-w-d, and cyclist's upper limbs is also moved, and drives front-wheel simultaneously and rotates, and alleviates the degree of fatigue of lower limb, makes sooner by bike, lighter, is easy to make, and cost is low.
The utility model is achieved through the following technical solutions, has wheel, handlebar, increase switching mechanism and transmission mechanism on the bicycle of car front fork, switching mechanism is by two identical unidirectional finishing bevel gear cuters, finishing bevel gear cuter 2, connecting rod 3, handlebar 4, axle 5 is formed, two unidirectional finishing bevel gear cuters are arranged in parallel on the axle 5, with finishing bevel gear cuter 2 Vertical Meshing, handlebar 4, connecting rod 3 is fixedly connected with finishing bevel gear cuter 2, connecting rod 3 flexibly connects mutually with car front fork 11, transmission mechanism is by big gear wheel 6, miniature gears 7, rotating shaft 8, hinge wheel 9, minor sprocket 10, chain 14 is formed, big gear wheel 6 is fixed on the axle 5 of switching mechanism, be meshed with miniature gears 7, miniature gears 7 and hinge wheel 9 are fixed in the rotating shaft 8, hinge wheel 9 is by chain 14 and minor sprocket coupling, and minor sprocket is fixed on the front truck wheel shaft, and axle 5 and rotating shaft 8 are by support 12,13 are fixed on the front vehicle fork 11.
The utlity model has reasonable in design, simple in structure, easy to use, etc. advantage.Because the front-wheel with the hand-drive bicycle rotates, and drives trailing wheel with pin simultaneously, has alleviated the fatigue strength of human body upper body, use both hands and feet when riding, make faster by bike easilyer, can be installed on bicycle, three-wheel vehicle, the disabled person's car, be particularly suitable for the elderly and use.

Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
Has wheel, handlebar, increase switching mechanism and transmission mechanism on the bicycle of car front fork, switching mechanism is by two identical unidirectional finishing bevel gear cuters 1, finishing bevel gear cuter 2, connecting rod 3, handlebar 4, axle 5 is formed, two unidirectional finishing bevel gear cuters are arranged in parallel on the axle 5, with finishing bevel gear cuter 2 Vertical Meshing, handlebar 4, connecting rod 3 is fixedly connected with finishing bevel gear cuter 2, connecting rod 3 flexibly connects mutually with car front fork 11, transmission mechanism is by big gear wheel 6, miniature gears 7, rotating shaft 8, hinge wheel 9, minor sprocket 10, chain 14 is formed, big gear wheel 6 is fixed on the axle 5 of switching mechanism, be meshed with miniature gears 7, miniature gears 7 and hinge wheel 9 are fixed in the rotating shaft 8, hinge wheel 9 is by chain 14 and minor sprocket coupling, minor sprocket is fixed on the front truck wheel shaft, and axle 5 and rotating shaft 8 are by support 12,13 are fixed on the front vehicle fork 11.
The front-wheel drive whole motion process is: set unidirectional finishing bevel gear cuter 1 and transmit torque backward, when handlebar 4 drives finishing bevel gear cuter 2 turning clockwises by connecting rod 3, at this moment, the right one-way finishing bevel gear cuter rotates backward axle 5, big gear wheel 6 on the axle 5 is by being meshed with miniature gears 7, driving rotating shaft 8 rotates forward, hinge wheel 9 drives minor sprocket 10 and rotates forward, thereby driving the car front-wheel rotates forward, when handlebar 4 turns left by connecting rod 3 drive finishing bevel gear cuters 2, the unidirectional finishing bevel gear cuter 1 in left side rotates backward axle 5, big gear wheel 9 is complementary with miniature gears 10 and chain 14, drive rotating shaft 8 and rotate forward, hinge wheel 9 drive minor sprockets 10 rotate forward in the rotating shaft 8, rotate forward thereby drive the car front-wheel.
Car front fork 11 rotates with the rotation of bicycle directional, and simultaneously, axle 5, rotating shaft 8 can freely be rotated on support 12,13, and the transmitting ratio of gear and sprocket wheel all is about 3: 1.By chain 14 phase transformation mechanisms the two-way rotation in the left and right sides of bicycle handle bar 4 is converted to unidirectional rotation, by transmission mechanism this unidirectional rotation is passed to the car front-wheel then, drive it and advance.
The effect of unidirectional finishing bevel gear cuter 1 is as the bicycle rear flywheel, when a direction is rotated, axle is transmitted torque, when another direction, only rotate and do not transmit torque, set 1 pair of little axle 2 of two unidirectional finishing bevel gear cuters and transmit torque backward, when handlebar 4 clockwise rotates by connecting rod 3 drive finishing bevel gear cuters 2 (turning clockwise), the unidirectional finishing bevel gear cuter 1 in left side freely rotates and does not transmit torque, and torque is transmitted in 1 pair of little axial back of right one-way finishing bevel gear cuter, when finishing bevel gear cuter 2 rotates counterclockwise, right one-way finishing bevel gear cuter 1 freely rotates and does not transmit torque, and left side 1 pair of axle 5 of unidirectional finishing bevel gear cuter transmits torque backward, like this, handlebar 4 cws no matter, rotate counterclockwise, the torque that is delivered on the axle 5 all is backward.
Unidirectional finishing bevel gear cuter is by the roller 16 of three Cylinder shapes, awl fluted disc 17, wheel body 18, axle 19 is formed, awl fluted disc 17 can freely rotate on axle 19, wheel body 18 and axle 19 fixed connections, in three wedge shape spaces 20 that roller 16 constitutes between wheel body 18 and awl fluted disc 17 respectively, roller 16 and wedge shape space 20 are parallel with the flank of tooth 21 of awl fluted disc 17, with the angle of axle 19 be 45 degree, when boring fluted disc 17 when wedge shape space 20 little ends rotate, roller 16 forms self-locking between awl fluted disc 17 and wheel body 18, awl fluted disc 17 belt wheel bodies 18 and axle 19 are rotated, when awl tooth 17 coils when wedge shape space 20 big ends rotate, roller freely rolls for 16 this moments, awl fluted disc 17 just rotates on axle 19, and wheel body 18 and axle 19 is not transmitted torque.
