Abstract
The utility model mainly relates to a driving mechanism for mechanical bicycles (such as a bicycle), which is composed of a lever power-assisted driving component. The mechanism is formed by that a lever-type seat handle drives a ratchet wheel, a steel cable, a guide wheel, a compressing and an extension springs, etc. via a chain. The utility model has the main effect that the utility model uses energy conversion generated by the weight of a human body to provide driving force for a bicycle. A bicycle with the mechanism can be ridden by both strong persons and weak persons with the effects of labor saving and lightness.
Description
The utility model relates to a kind of transmission device of mechanical bicycle, particularly the power-assisted bicycle driven transmission device of being made up of lever, chain and ratchet.
The transmission device of existing bicycle is the crank that pedal is housed by a pair of, is installed in that sprocket wheel on the axis and the flywheel on the rear axle and chain form.In the prior art of this technology,, just on transmitting ratio, improve to some extent to transmission mechanism of bicycle.As variable speed bicycle, be still sprocket wheel and chain gear.Do not change the effect of merit, do not have the power-assisted effect.
Task of the present utility model is: on the basis of standard bicycle type of drive, design a kind of human body gravity that utilizes, by the transmission servomechanism that seat handle lever, chain and sprocket wheel are formed, it is brisk laborsaving that the cyclist is particularly ridden under the condition of road surface frustration in riding.
Task of the present utility model is finished by following mode: supporting member on the double crossbeam is connected with a seat handle attaching parts hinge by being fixed on, bearing fit.Seat handle upper end and crossbeam, back cant beam, rear crotch intersection mounting spring.Connected an end of steel rope on the seat handle lower end by locking piece, the leading sheave before the other end of steel rope is walked around and is fixed on cant beam and the under-carriage is connected with an end of chain.The other end of chain is connected with extension spring on being fixed on under-carriage through the ratchet that is fixed on the hind axle skin.After the cyclist took a seat, human weight produced potential energy, and this energy is directly delivered on the driving wheel by said mechanism.When human body rose and fell with vehicle ', this transmission device was under the effect of spring force, and seat handle lever affects chain to drive ratchet by its steel rope that is connecting.Make it repeat function, constantly produce the transmission power-assisted.
The utility model has following advantage compared with the prior art:
1, laborsaving, brisk.
The utility model has been owing to adopted lever transmission mechanism, riding the energy that the time spent utilizes human body to rise and fall and produce, changed the effort situation of standard bicycle at difficult road traveling, and not having physically, power can both reach brisk labour-saving purpose.
2, simple in structure, safe and reliable.
The utility model and existing various variable speed bicycle structure compared are simple.As long as change one cross sill and seat handle refill leading sheave and left side ratchet, steel rope, chain get final product.Performance is safe and reliable.
Structure of the present utility model is provided by following examples and accompanying drawing:
Fig. 1 is the structural representation according to the morpet of utility model proposition.
Fig. 2 is the servodrive structural representation.
As shown in Figure 1 and Figure 2:
A handle supporting member (3) is housed on the double crossbeam of inclined (4).Seat handle attaching parts (17) is fixed into one with seat handle (1), is connected bearing fit with supporting member (3) hinge.The seat handle (1) of saddle (14) end is equipped with compression spring (2) with the intersection of back cant beam (13), crossbeam (4), rear crotch (12).Fixing locking piece (15) on preceding cant beam (8) and the under-carriage (16), leading sheave (6) and extension spring (11) are being housed on locking piece (15).The car backshaft skin is equipped with ratchet (10) on the left side.One end of steel rope (7) is connected with seat handle (1) lower end locking piece (5), and the other end is connected with an end of chain (9) through leading sheave (6).The other end of chain (9) is walked around ratchet (10) and is connected with extension spring (11).
In sum, the potential energy that produces that rises and falls of human body is transferred on the driving wheel of bicycle by said mechanism by bike, converts kinetic energy to, reaches power-assisted purpose.
