Abstract
The utility model discloses a stepless speed changing and limiting mechanism for the engine of the motorcycle, comprising a driving wheel assemble, a driven wheel assemble and a leather belt provided between the driving wheel assemble and the driven wheel assemble. The driving wheel assemble comprises a shaft sleeve installed on a left crank and a left and a right semi-driving wheel component; the upper sleeve of the shaft sleeve between the left and right semi-driving wheel components; the design still adopts the existing stepless speed changing mechanism for the engine of the motorcycle, and adds a speed regulating liner arranged on the upper sleeve of the shaft sleeve between the left and right semi-driving wheel components; thus the speed transmission range of the speed regulating system can be adjusted, and the control the speed of the motorcycle with available range; changing the length of the speed regulating liner can satisfy with different states.
Description
Technical field
The utility model relates to a kind of motor cycle engine, particularly a kind of motor cycle engine stepless change speed limiting mechanism.
Background technology
The motor bike that some FYAs use has appearred in the market, as: the motor bike that beach buggy, children use etc., it is low with respect to the desired speed of the motor bike that is used to exercise, in order to reach the effect of adjusting speed range and speed limit, typically use following one or more and make up mutually and realize: 1, changed performance perameter by revising the CDI circuit; 2, by the construction parameter of adjustment roller guide plate and the weight of centrifugal roller; 3, by adjusting the angle of wedge and the belt that right half assembly of a driving wheel left side half assembly and driving wheel forms; 4, by changing the transmitting ratio of two pairs of gears of rear gear box; Though above-mentioned method can reach the effect of adjusting speed range and speed limit, but the change to former car is bigger, and for the different maximum speed of revolution of correspondence, needs pairing different gear or special purpose parts, so just increase cost of product, also brought inconvenience for simultaneously production control.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of motor cycle engine stepless change speed limiting mechanism simple in structure.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of motor cycle engine stepless change speed limiting mechanism, comprise driving wheel combination, flower wheel combination, between driving wheel combination and flower wheel combination, be connected with belt, the combination of described driving wheel comprise the axle sleeve that is installed on the left crank and about half drive wheel assemblies, about be set with the speed governing lining on the axle sleeve between half drive wheel assemblies.
The beneficial effects of the utility model are: the utility model need not change original motor cycle engine stepless speed changing mechanism, only need about suit speed governing lining on the axle sleeve between half drive wheel assemblies, just can reach and adjust the speed governing system gear range, thereby the maximum speed of control motor bike is in scope of design, and by changing the length of speed governing lining, just can satisfy the requirement of different conditions, in addition, can also reduce the friction drag of driving system, improve engine power performance and economy, prolong the service life of belt.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of original motor cycle engine stepless speed changing mechanism;
Fig. 2 is the structural representation of driving wheel combination of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of motor cycle engine stepless change speed limiting mechanism of the present utility model, comprise driving wheel combination 1, flower wheel combination 2, between driving wheel combination 1 and flower wheel combination 2, be connected with belt 3, described driving wheel combination 1 comprises the axle sleeve 13 that is installed on the left crank 12, half drive wheel assemblies 14,15 about being equipped with on the axle sleeve 13, on the space about belt 3 is installed between half drive wheel assemblies 14,15, about be set with speed governing lining 4 on the axle sleeve 13 between half drive wheel assemblies 14,15.
The principle of work of motor cycle engine stepless speed changing mechanism is: driving engine rotates by the roller guide plate 11 that left crank 12 drives in left half drive wheel assemblies 15, the also corresponding increase of centnifugal force that when rotating speed increases, produces, centrifugal roller 16 in the roller guide plate 11 is under action of centrifugal force, raceway along roller guide plate 11 outwards flies out, thereby force left half drive wheel assemblies 15 to move right, belt 3 is also outwards extruded simultaneously, thereby the radius of action of driving wheel combination 1 is increased, again because driving wheel combination 1 and flower wheel makes up 2 width between centerss and belt 3 length are constant, spring 21 in the flower wheel combination 2 moves down, the radius of action of flower wheel combination 2 reduces, and then motor bike gives it the gun; Otherwise, engine speed reduces, the also corresponding minimizing of centnifugal force at this moment, moves on the spring 21 in the flower wheel combination 2, belt 3 is also outwards extruded, the radius of action of flower wheel combination 2 is increased, force left half drive wheel assemblies 15 to moving to left simultaneously, centrifugal roller 16 is inwardly received, radius of action reduces, thereby motor bike is slowed down.
From the principle of work of motor cycle engine stepless speed changing mechanism as can be known, in the process that motor bike quickens, be exactly that speed governing lining 4 moves to right therewith in driving wheel combination 1 process that moves to right, when speed governing lining 4 pushes up right half drive wheel assemblies 14, the radius of action of driving wheel combination reaches maxim, and when being certain value, the motor bike speed of a motor vehicle at this moment also corresponds to the max speed, therefore, by changing the length of speed governing lining 4, can change speed adjustable range, can limit the max speed simultaneously.
Certainly also axle sleeve 13 and speed governing lining 4 can be made of one in the use; be shaft shoulder mode and limit moving to right of driving wheel combination 1; also can realize reaching the effect of speed limit; no matter thereby use which kind of mode; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
