Abstract
The utility model discloses a gear of non-motor vehicles, which is a sliding-block speed-regulating gear-drive device. The device takes a pedal wheel as a driving gear, and a planetary wheel arranged on an eccentric shaft is driven by a transmission gear. When the pitch circle diameter of the planetary wheel is equal to one half of the pitch circle diameter of an inner gear which meshes with the planetary wheel, the motion state of any point on the pitch circle of the planetary wheel is a reciprocating linear motion passing through the peripheral core of the inner gear. According to the principle, the cooperation of a connecting rod fixed on the pitch circle of the planetary wheel and sliding members converts the reciprocating linear motion into a rotary motion through the meshing of racks and pinions. The speed-regulating process is carried out by only utilizing a control knob to drive the internal gear so as to drive the planetary wheel to deflect a proper angle simultaneously.
Description
The utility model belongs to the unpowered vehicle speed-regulating actuator, is specifically related to the stepless speed regulating drive device of a kind of bicycle or manual tricycle.
The transmission of existing bicycle all realizes that by sprocket wheel and chain its transmission system mainly is the sprocket wheel of one group of different-diameter, realizes step change by the chain sprocket engagement different with diameter in the transmission process.The shortcoming of this speed-regulating actuator shows because of the motion at grade of sprocket wheel and chain, and has side force, so very easily produce wearing and tearing, this kind apparatus structure is loaded down with trivial details in addition, install and maintenance very inconvenient.
The purpose of this utility model is to provide a kind of gear---the sliding type stepless speed regulating drive device, reach the simplification speed-changing mechanism, and realize the technique effect of infinite speed variation.
For achieving the above object, the utility model has adopted the technical scheme shown in Fig. 1 and Fig. 2.
Fig. 1 is the assembling scheme drawing of the utility model running part.
Fig. 2 is the speed governing drive mechanism scheme drawing that has speed regulation device.
Wherein running part is by the driving gear 1 and travelling gear 2 engagements that are installed on the axis 13, gear 2 is installed on the eccentric shaft 8, eccentric shaft 8 hinge joint planetary gears 4, planetary gear 4 and internal gear 3 engagements that are installed on the axle sleeve 9, be fixed with connecting rod 10 at planetary gear 4 pitch circles, slide block 11 hinge joints in connecting rod 10 and slider component 12 guide grooves, the other end of slider component 12 are two toothed rack 5 and 6, two toothed rack and are installed in separately up and down engagement of coaxial two one-way clutch (ratchet); Its speed adjusting gear affects sprocket wheel 15 rotations by a backguy 14 that links to each other with handgrip control turn-knob, sprocket wheel 15 drives screw mandrel 16 and rotates simultaneously, assembling slider nut 17 on the screw mandrel 16, slider nut 17 is installed in the guide groove with the affixed slider component 18 of internal gear 3, when screw mandrel rotates, slider nut 17 slides in the guide groove of member 18, drives simultaneously member 18 and internal gear and rotates.
As the further improvement of the utility model technical scheme, connecting rod 10 members 12 direct and with tooth bar that are fixed on planetary gear 4 pitch circles can be linked mutually.
Transmission of the present utility model and transmission principle are as follows: when driving gear rotates, driving transmission gear 2 rotates, eccentric shaft 8 rotates simultaneously thereupon, satellite gear 4 hinge joints are on eccentric shaft 8, also in company with eccentric shaft 8 transmission together, satellite gear 4 and inner gear 3 engagements, so satellite gear 4 carries out rotation when doing revolution, two/for the moment of inner gear 3 pitch circles that equal to be engaged with when the satellite gear pitch circle diameter, the straight-line motion in the inner gear center of circle is all passed through in any point on the satellite gear pitch circle at work in motion process, according to this principle, connecting rod 10 is fixed on the pitch circle of satellite gear 4, slide block 11 or direct and member 12 hinge joints by linking with it then, thereby realization has the linear reciprocating motion of the member 12 of tooth bar, tooth bar on the member 12 is two toothed rack that split, and it meshes on upper-lower position with being installed in coaxial two free-wheel clutchs (ratchet) respectively, so carry out in the linear reciprocating motion process realizing being installed in the continuous rotation of axle on the free-wheel clutch at tooth bar.When the needs speed governing, only need affect backguy 14, then by sprocket wheel 15, screw mandrel 16, the interlock of slider nut 17, drive slider component 18 and inner gear 3 and rotate a required angle together, thereby certainly will drive the planetary wheel 4 that is meshed with inner gear and rotate equal angular, any point obtains changing to the distance projected length in the horizontal direction between the slide block 11 on planetary wheel 4 pitch circles thereby make, this variation promptly is the tooth bar change of up stroke in the horizontal direction that links with it, thereby the change by rack stroke reaches free-wheel clutch (ratchet) change in rotational speed that is engaged with, and promptly reaches the purpose of speed change.
Advantage of the present utility model is: the change chain gear is gear transmission, improved the reliability of transmission, speed change has realized infinite speed variation, simplified the loaded down with trivial details mechanism of traditional speed regulation device, and speed ratio can fit and need to select arbitrarily, in addition, utilize the utility model, the bicycle cw still is that conter clockwise scrunches and guarantees that all bicycle moves ahead, thus firmly attitude that can the mediator, to reduce fatigue.
