Description
Technical field
The utility model is related to a kind of steering gears of bicycle, and in particular to the upper limb of people a kind of and lower limb whole body
The steering gear for reciprocating Exercycle of cooperation walking.
Background technology
The standard bicycle feature that people use at present is that human upper limb is divided the work with lower limb, i.e., upper limb is mainly responsible for control
Direction, lower limb are mainly responsible for offer power, are analyzed by the centripetal force and centrifugal principle of mechanics, are exactly that upper limb is mainly responsible for control
Centripetal force, it is ensured that the balance of vehicle；Lower limb, which are mainly responsible for offer centrifugal force, ensures moving ahead for vehicle.But to more than human lumbar most
For the present situation that significant points cannot effectively take exercise, this be undoubtedly standard bicycle all the time there are the defects of.
In the previous patent of invention of the applicant（Patent No. ZL 201110287532.4）In the technical solution proposed,
Especially it is being related to steering gear design aspect existing defects.It is fixed with outer space auricle in handlebar casing lower outside
Bogie, but there are following design defect among these：First, drive rod and two external hollow lifting lug designs are in the same plane, this
It is that belt transect comes as a result, when drive rod lower end be in front end and minimum point and handlebar casing is driven to be turned to, two outer spaces
Angle of the heart lifting lug between bracing wire is acute angle, can seriously affect the effect of the steering of front vehicle wheel at this time；Second is that around fixing
Space length and external hollow between two external hollow lifting lug lower ends that interior lifting lug bearing block on cant beam is rotated
Relationship between the length of lifting lug in above-below direction do not describe it is clear, moreover, the spacing between two external hollow lifting lug lower ends
It is also clear without describing with the ratio of ratchet wheel diameter；Third, two external hollow lifting lug lower ends are connected respectively bracing wire
The center line of line and shaft between tie point should point-blank, but in Patent No. ZL
201110287532.4 it is then in narration in：The external hollow lifting lug（14）With two bracing wires（16）Between two tie points
Line and interior lifting lug bearing block（13）Central axes coincide, the description is not it is clear that can cause the misunderstanding of people.To sum up institute
It states：It is analyzed according to the motion principle of gyroscope, there are problems that above or there may be can cause in bicycle actual use
The defects of being runed counter to when turning to dynamically working, brings insecurity.

It crosses fastening bolt and is fixed with outer space auricle bogie, being respectively fixedly connected with steering with right side on the left of the auricle bogie of outer space hangs
Ear, the both ends for turning to chain are connect respectively by a bracing wire with a steering lifting lug lower end, and Guy wire guide-tube is arranged with outside bracing wire,
Two bracing wires both pass through bracing wire fixed frame and tight are fixedly connected with turning to the both ends of chain respectively；The steering lifting lug lower end in left side
With the tie point of bracing wire and the line turned between lifting lug lower end and the tie point of another bracing wire on right side and axis
Center line coincides；
The tie point for turning to lifting lug lower end and bracing wire in left side and the steering lifting lug lower end on right side and another bracing wire
Tie point between length be more than ratchet-gear wheel diameter length.
Two to turn to the distance between lifting lug lower end suitable with turning to the length of lifting lug in above-below direction；Lifting lug is turned to driving
The angle that plane where lever rotary motion trace is formed is acute angle.
Easily changeable axle sleeve is provided between axis excircle and interior lifting lug bearing block inner wall, is set on interior lifting lug bearing block
There is lubricating oil oil filler point.
Using above-mentioned technical proposal, between the tie point for turning to lifting lug lower end and connecting two bracing wires in the utility model
The center line of connecting line and axis coincides, and designs this construction and is consistent with the operation principle of gyroscope.Because either
Still manipulated in drive rod front-rear reciprocation movement handlebar casing turn to when, all be around middle shaft centre line intermediate point make justify
Zhou Yundong's, therefore, both work can each does what he thinks is right and does not interfere with each other.
The tie point for turning to lifting lug lower end and bracing wire in left side and the steering lifting lug lower end on right side and another bracing wire
The distance between tie point be more than the diameter of ratchet-gear wheel；The gearratio of steering can be improved in this way, make the vehicle rotated during steering
Rotational angle gripping tube is smaller, and front-drive angle is larger, can improve the gearratio of steering.
Two to turn to the distance between lifting lug lower end suitable with turning to the length of lifting lug in above-below direction；Lifting lug is turned to driving
The angle that plane where lever rotary motion trace is formed is acute angle.Structure is more reasonable, and when steering is more laborsaving.This structure with
The principle of gyroscope is corresponding adaptation.
Generate friction since axis carrys out back rotation in interior lifting lug bearing block, in order to reduce frictional force, axis excircle with
Easily changeable axle sleeve is provided between interior lifting lug bearing block inner wall, lubricating oil oil filler point, compartment are provided on interior lifting lug bearing block
Time injects lubricating oil, reduces frictional force, and extend the axle sleeve service life.
In conclusion the utility model has carried out knuckle section the improvement in structure, technical solution is optimized, transmission is more
Adduction is managed, and improves transmission efficiency and the service life of component.
