Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is described in detail.
Before the present invention is described in detail, it shall be noted that in the following description content, similar element is with identical
Numbering representing.
Refering to Fig. 2, the first embodiment of front-wheel drive rear-wheel steering bicycle of the present invention includes a Frame unit 2,
The counterweight element 5 of steering unit 4, of individual driver element 3, and one take unit 6.
The Frame unit 2 is arranged under the front end of frame body 21 including the frame body 21, that is in font
The front fork stem 22, one of side is hubbed at after 23, one, the front-wheel of the front fork stem 22 is hubbed at below the rear end of frame body 21
Fork arm 24, and a trailing wheel 25 for being hubbed at the rear fork 24.
The frame body 21 has one and sets with the counterweight element 5 in horizontal 211, confession rear fork 24 of handle base
Put and in horizontal rear wheel seat 212, and one connects the handle base 211 with the rear wheel seat 212 and for the setting of front fork stem 22
Body frame 213.
The driver element 3 includes the crank 31 of two two opposition sides for being hubbed at the front fork stem 22 respectively, and two difference
(because of the relation of projection view angles, crank 31 described in Fig. 2 and the pedal 32 only show it to be hubbed at the pedal 32 of the crank 31
In one).
The pedal 32 is trampled for rider, and directly drives the front-wheel 23 along own axis by the crank 31
And advance, compared with the mode of use chain drum common on the market, the weight of car body can be mitigated and the manufacturing cost of dealer is saved.
Refering to Fig. 3 and Fig. 4, the steering unit 4 includes 41, two difference of handlebar stem for being hubbed at the handle base 211
The driving member 42 of the handlebar stem 41 and the rear fork 24 is fixedly arranged on, and one is connected to the driving member 42 and can interlock the biography
The transmission belt group 43 that moving part 42 is rotated in the opposite sense.In the present embodiment, the driving member 42 is in the form of annular discs, but not as
Limit.
There are the transmission belt group 43 two to intersect extension along the body frame 213 and two ends are arranged in respectively the driving member 42
Transmission rope 431, and two protection nooses 432 for intersecting extension along the body frame 213 respectively and stretching through for the transmission rope 431.
During steering, the rider turns handlebar stems 41 rotates the one of driving member 42 for being fixedly arranged on the handlebar stem 41,
And the transmission rope 431 for being fixedly arranged on the driving member 42 interlocks again another driving member 42 and is rotated in the opposite sense, and drive should
Trailing wheel 25 is turned to, and force is trampled by the rider because the trailing wheel 25 is no during steering, therefore can effectively be subtracted
It is few to turn to required strength.
Refering to Fig. 2 and Fig. 5, the counterweight element 5 includes a counterweight for being arranged at the rear wheel seat 212 and the neighbouring trailing wheel 25
The bottom 52 of pipe 51 and spiral shell located at the counterweight tube 51.
The counterweight tube 51 has the upper extension 511 and a lower extension for extending towards upper and lower two-phase opposite direction respectively
512, internal face of extension 511 and the lower extension 512 is engaged and defines one and place space 513 on this.The bottom 52
Root edge of the spiral shell located at the lower extension 512.
This is taken unit 6 and is fixedly arranged on the seat pipe 61, for placing space 513 including one and can be arranged at up or down
The height that the arm 62, that in the seat pipe 61 and upper end is exposed is arranged at the top of seat pipe 61 to control the movement of arm 62 is adjusted
Whole device 63, and a seat cushion 64 for being arranged at the top of arm 62.
The rear wheel seat 212 is arranged at by the counterweight tube 51, and this is taken unit 6 and is arranged at this of the counterweight tube 51 and places
Space 513, make it is of the invention with existing front-wheel drive rear-wheel steering bicycle 1 (see Fig. 1) in comparison, center of gravity is relatively low and relatively leans on
The nearly trailing wheel 25, when rider rides on the seat cushion 64, the rider weight of itself can't be by lever principle to this
Front-wheel 23 applies a torque upwards, therefore, the front-wheel 23 can stably fit in ground during advance is rotated, and enter
And the stability of lifting operation.
Be the second embodiment of front-wheel drive rear-wheel steering bicycle of the present invention refering to Fig. 6, the second embodiment similar to
The first embodiment, major difference is that：The body frame 213 of the frame body 21 is slightly U-shaped with one and connection should
The depressed part 214 of rear wheel seat 212, and the lower extension 512 of the counterweight tube 51 is arranged at the depressed part 214 with being integrally formed,
Consequently, it is possible to the present embodiment can equally reach effect of the lifting operation stability such as first embodiment.
In sum, the present invention is mitigated the weight of car body by the driver element 3 and saves manufacturing cost, and utilization should
The assisted diversion of steering unit 4, meanwhile, by the setting of the counterweight element 5 and position that this takes unit 6 is adjusted changing riding
When center of gravity, make the front-wheel 23 that ground, and then the stability of lifting operation can be stably fitted in during advance, so
Really the purpose of the present invention can be reached.
