Description

Double-driving bicycle

The utility model belongs to the bike tech in the trackless terrestrial vehicle, and it relates to a kind of structure of new bicycle.

Bicycle is the most general walking-replacing tool in present people's lives, and the owning amount of China's bicycle is the first in the world.The birth of bicycle has 500 years history, and it is from wooden wheel, has experienced steel structure, steel-plastic structure and then strides forward to overall plastic structure, from single speed, has developed into the bicycle of interior three speed, outer five speed, outer ten speed, outer 15 fast iso-variable velocity types.But, though bicycle has experienced the ever-changing pattern of not breaking away from single wheel drive all the time.The bicycle of this single wheel drive is general, and only upper body and upper limbs are almost motionless with pedaling enough, and it is not only painstaking to ride for a long time, and often feel upper limb numbness and lower limb are ached, and the speed of bicycle is also unhappy.The current vehicle that also has various hand-drive forms for disabled persons.Know that through investigation the bicycle of two drive forms of using both hands and feet is beyond example still at present.

The purpose of this utility model is in order to overcome the defective of present bicycle use legs and feet list drive form, a kind of two drive forms of using both hands and feet and working simultaneously of special proposition, it not only can increase power and improve the special difficult situation of velocity adaptive, can also allow the upper body upper limbs participate in motion, and improve original active situation and fatigue state.

By as above design, the double driving bicycle that this programme provided includes the driver train of vehicle frame, car saddle, front and back wheel and the trailing wheel of ordinary bicycle, and its concrete feature is the driver train that it also side by side has front-wheel.

Front-wheel drive system in this programme is a kind of driver train of hand sprocket wheel chain gear that can steering, it be by axle sleeve (12), bearing (13), the drive axle (11) of the part of very protracting, have sprocket wheel (14) right rocking arm (17), have can 180 ° of conversion location left half axle axle sleeve (9), left half axle axle sleeve retainer spring (8), left rocking arm (2), left rocking arm on locating dowel pin (6), connection locating dowel pin (16), axle sleeve on two rocking arms on extend out left arm knock hole arm (10), and two hold crank (1) and constituted.Wherein, the dog coupling by can 180 ° of conversions between left half axle axle sleeve (9) and the drive axle (11) connects, and left half axle retainer spring (8) is a stage clip, pushes to left half axle axle sleeve (9) right-hand after gland (7) is installed.Finger is radially arranged on the locating dowel pin on the left arm (6), it is contained on the left rocking arm (2) by location key seat (4) and pressing plate (3), promotes the hole that locating dowel pin cooperates with it on away from dowel hole arm (10) in that stage clip (5) is housed under the finger of locating dowel pin during installation.Its bearing (13), connection locating dowel pin (16) all adopt the structure of bicycle middle shaft, hold the structure that crank (1) adopts bicycle pedal.

The front driving mechanism of this programme is the chain-driving form, and its chain is the ordinary bicycle chain, omits in Fig. 2, and bicycle freewheel is housed on front-wheel.Can twoly drive when riding, also can singly drive, promptly list drives with hand with pin or list.Earlier left rocking arm is pushed away left during without hand-drive, transfer to tooth embedding localization part, left arm or right arm rotation push left arm for 180 ° again makes its pin fixed, shaking both arms makes locating dowel pin (6) aim at the hole of dowel hole arm (10), push away locating dowel pin and advance the Kong Bingyong finger and dial extremely, the left and right sides crank of this moment just forms the handlebar of common car.Its operation is with aforesaid opposite when using before driving, because before driving axle sleeve (12) protract one section very on, has certain brachium, thus easily grasp direction shaking Shi Yineng, and motion does not upward have interference.During this cycling, can use both hands and feet simultaneously drives, but also trick alternation adjusting motion form relieving fatigue, and can also fix left and right sides rocking arm becomes the form identical with ordinary bicycle.

Therefore this programme has following preceence: 1. can increase power with two drive forms when contrary wind or upward slope; Can increase power when 2. on flat road surface, adopting two drive form and improve the speed of a motor vehicle, can be increased to 20-25 kilometer/hour by 15 kilometers/hour of common car; 3. make human upper limb participate in motion, improved labor condition and can reduce tired; 4. it is a kind of later-model walking-replacing tool, also is desirable fitness tool.

Fig. 1 is the general illustration of this programme double driving bicycle.

Fig. 2 is the structural representation of this programme before driving part.

Structure below in conjunction with description of drawings this programme, drive axle (11) is supported on the axle sleeve (12) of the part of very protracting by bearing (13), extend dowel hole arm (10) on the axle sleeve, sprocket wheel (14) is fixed on the right rocking arm (17), overlapping left half axle axle sleeve (9) on the left end of axle drive shaft (11), have between the two can 180 ° of conversions castellated hookup, act on stage clip (8) through gland (7) and make semiaxis axle sleeve and axle drive shaft (11) stable bond, but transfer torque.All use between left and right sides rocking arm (2) and (17) and the axle drive shaft and connect locating dowel pin (16) and connect fixing.Pressing plate (3) location key seat (4), stage clip (5) and locating dowel pin (6) are housed on left rocking arm (2), one radially finger is arranged on the locating dowel pin, straight trough that adapts and the little translot of locating usefulness for finger are arranged on the location key seat, under the effect of stage clip, locating dowel pin has the trend away from the dowel hole arm (10) that has dowel hole, the termination of two rocking arms is equipped with two and is held crank, this crank adopts the structure of bicycle pedal, and the wheel disc of sprocket wheel (14) can connect with the transmission moment of torsion by the flywheel on chain and the front-wheel.This programme is through its performance ideal of evidence of sample car, can brothers and usefulness, can be used alternatingly, and also can use by the form that the ordinary bicycle list drives.It can improve speed, can improve labor condition when riding to lessen fatigue, and reaches design idea more fully.
