Description
The utility model belongs to the mechanical device field, particularly relates to a kind of transmission system of bicycle.
Bicycle is in the process of riding, and particularly the road surface landform is changeable or long apart under the situation, and the bicyclist often wishes according to circumstances to change the speed of a motor vehicle.The change of the bicycle speed of a motor vehicle is commonly regulated by mechanical device except that power adjustment.Serial derailleur as the production of Jiangsu Province's Changzhou gold lion bicycle industry and trade group company, the flywheel of its trailing wheel is that the fluted disc that a plurality of diameters are different overlaps (title cone pulley), reaches the speed change purpose by driving chain with the natural scale that changes flywheel and pedal wheel disk that articulates of different fluted discs.This transmission system is by the gear of the quantity decision speed change of Flywheel fluted disc, and speed change has rank; The loss of transmission process medium power is many, mechanical wear is big; Speed-change process is by dialling the chain device chain to be dialled to another fluted disc from a fluted disc, is prone to chain jamming, thereby causes speed change not in place.
The utility model is the weak point at above-mentioned existing derailleur, provides that a kind of speed range is big, reliable in structure, processing ease, practical stepless derailleur.
The technical scheme that realizes the utility model purpose is such.This change-speed box comprises slip gear piece, speed change dish, tray deck and damper brake.Two relative tray decks are connected and fixed by spider and check screw, and slip gear piece and slide block are housed therebetween, and slip gear piece and slide block can be made into one.The slide block that has chute is positioned at the slide opening of two stands dish.The two stands dish that is connected and fixed is sleeved on the pedal spindle.The speed change dish by reaction plate and screw retention on pedal spindle.The speed change dish is provided with helical mount, the chute tabling on helical mount and the slide block, and the another side of the speed change dish relative with helical mount is provided with trig loop, can match with damper brake.The slip gear piece be provided with can with driving chain mating teeth tooth.The slip gear piece can be under the driving of speed change valve snail swing frame, and the slide block by its pros and cons slides up and down along the slide opening of tray deck, and it is located by helical mount on the speed change dish and the chimeric realization of the chute on the slide block.The slip gear piece that is installed on the tray deck is no less than three, and equidistantly is evenly equipped with on the tray deck, and the slip gear piece is fan shape.Its function is equivalent to pedal wheel disk, is the center of circle with the tray deck hole heart, and the slip gear piece can entad be done or centrifugal motion along the tray deck slide opening, to change the diameter of pedal wheel disk, reaches the speed change purpose.When the needs speed change, the lock circle on the tight speed change dish of damper brake lock, the rotation of pedal spindle makes the helical mount on the speed change dish produce relative motion by chute on the slide block and slip gear piece, and the distance of slip gear piece and pedal spindle changes, and produces speed changing effect.The take-off the brake lock makes it break away from the lock circle, and the relative motion of speed change dish and slip gear piece stops, and just can produce the effect of fixed vehicle speed.
The utlity model has following advantage:
1, the utility model can make bicycle carry out stepless change within the specific limits, and speed range is big.
2, the utility model enforcement speed change can be carried out in the bicycle running process, also can implement when stagnation of movement.
3, the utility model and existing ordinary bicycle have good matching, when the existing order of repacking is driven a vehicle, only need change original pedal wheel disk into the utility model, and the correct position that annex damper brake of the present utility model is installed on the bicycle gets final product.
4, the utility model dependable performance, processing ease, and easy to maintenance.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
