Abstract
The utility model relates to a bicycle reducing chain wheel for speed change in the driving of a bicycle. The bicycle reducing chain wheel consists of a shaft sleeve, a traction plate, a chute plate, a slide sleeve, a connecting strip, a tooth block, a positioning spring piece and the like, wherein the shaft sleeve is riveted with the traction plate into a whole body; the chute plate is riveted with the slide sleeve into a whole body; a plurality of equal oblique ladder-shaped chutes are formed on the chute plate; a ratchet and a ratchet spring are arranged on the tooth block, and a sliding pin is arranged at one side of the tooth block; the chute plate and the slide sleeve are sleeved on the shaft sleeve during the assembly; the shaft sleeve traction plate ensures that the sliding pin of the tooth block slides in the chute of the chute plate through the connecting strip; the positioning spring piece is installed on the side surface of a pedal or on the shaft sleeve and is stopped at a certain gear with a gear positioning hole of the chute plate; when the bicycle reducing chain wheel is in use, the traction plate and the chute plate synchronously rotate along with the pedal; when the speed is changed, a gear shifting device is pulled to press or clamp notches on the outer edge of the chute plate, the chute plate does not move, and the traction plate rotates forwards along with the pedal and drives the connecting strip and the tooth block to move towards the center through the guiding chutes and stop in the position of a next ladder chute; the bicycle reducing chain wheel is equivalent to a small chain wheel and is reduced in speed; and if the pedal rotates backwards, the chain wheel is largened, and the speed is accelerated.
Description
Technical field
The utility model is intended to propose a kind of bicycle diameter-variable chain wheel, is used for the usefulness that bicycle running is regulated the speed.
Background technology
At present; Bicycle has become a kind of common in people's daily life and the vehicle easily; For satisfying the traveling comfort of riding; Usually rear flywheel is designed to the chain sprocket structure of the different sizes of multilayer, makes chain work in the different transmitting ratio of generation on the different sprocket wheels through chain puller, to change moving velocity.This method adopts the multilayer sprocket wheel, chain often is under the curved attitude of knob works, and be prone to cause the wearing and tearing and the damage of chain, and the converter speed ratio between every retaining is little, complex structure, and cost is higher simultaneously, on the high retaining bicycle, can not popularize in generally being assemblied in comprehensively.
Summary of the invention
Exist between every retaining converter speed ratio little for overcoming bicycle multilayer sprocket wheel; Be prone to cause the bent wearing and tearing of chain knob; The utility model proposes a kind of bicycle diameter-variable chain wheel, replace the multilayer sprocket wheel to carry out bicycle shift with a diameter-variable chain wheel, and converter speed ratio is big; Make chain work at grade, effectively reduced the wearing and tearing of chain.
The technology implementation scheme that the utility model proposes is: diameter-variable chain wheel is by axle sleeve, sheave, chute dish, sliding sleeve; It is whole that connecting strap, tooth piece, compositions such as positioning reed, axle sleeve become with the sheave riveted; It is whole that the chute dish becomes with the sliding sleeve riveted, and many oblique stepped appearance chutes of five equilibrium are arranged on the chute dish, by the centre retaining of deciding hole arranged, and the chute web is along jagged (or embossing); Ratchet and ratchet spring are arranged on the tooth piece, protect the chain sheet, a side has sliding pin (can install sliding sleeve additional), and connecting strap one end and tooth piece are fixed; The connecting strap other end is connected with the moving riveted of connecting pin with sheave, and chute dish and sliding sleeve are loaded on the axle sleeve during assembling, slide on the axle sleeve to rotate (can install ball additional between axle sleeve and sliding sleeve) flexibly, and the axle sleeve sheave slides against in the guiding groove of chute dish tooth piece sliding pin through connecting strap; The tooth piece is stopped at different ladder runner positions, is equivalent to the sprocket wheel of different-diameter, and connecting strap and tooth piece number equate with chute, and positioning reed is contained in and keeps off the hole surely with the chute dish on pedal side or the axle sleeve and stop at a certain gear; During use, sheave and chute dish rotate with pedal synchronously, and at maximum position, the tooth piece is still in the outer of chute dish like fixed retaining; Equivalence is maximum, fastest for connecting wheel, during speed change, pulls shift-shifting device (being improved by existing shift-shifting device) and pushes down or block chute dish outer breach (or embossing); This moment, the chute dish was motionless, and sheave continues to rotate forward with pedal, and drive connecting strap and tooth piece move to the center through guiding groove and be parked in next ladder runner position; Be equivalent to a little sprocket wheel, sprocket wheel diminishes, and speed reduces; Rotate backward like pedal, it is big that sprocket wheel becomes, and speeds up.Diameter-variable chain wheel can be contained in and do driving wheel on the bicycle pedal, also can be loaded on and do flower wheel on the rear flywheel.
The utility model replaces the multilayer sprocket wheel with a diameter-variable chain wheel, and simple in structure, chain works on the same plane; Reduce the knob power and the wearing and tearing of chain, adopted ratchet structure, become retaining flexibly; The ability multi-gear transmission can carry out large velocity ratio simultaneously and dial retaining, has improved the traveling comfort of cycling.

The specific embodiment
In Fig. 1～5; Be loaded on the axle sleeve behind chute dish (3) and sliding sleeve (4) riveted, sliding sleeve can freely rotate on axle sleeve, is loaded on the bicycle middle shaft behind axle sleeve (2) and sheave (1) riveted; Axle sleeve left side dress pedal also rotates synchronously; Tooth piece (6) and ratchet (8), ratchet spring (9), sliding pin (7), protect chain sheet (10) and connecting strap (5) is assembled into integral body, connecting strap is assemblied on the sheave through connecting bore (17) and connecting pin (11), and the sliding pin of tooth piece (7) is loaded in the guiding groove (12) of chute dish; Positioning reed (14) can be contained on pedal side or the axle sleeve, and keeps off hole (15) surely and makes the chute dish be parked in a certain gear.In the cycling; Push down group retaining breach (16) when pulling group retaining link gear; Chute dish (3) stops operating; Pedal continues to rotate forward, in the guiding groove (12) of chute dish (3), slides to ladder chute (13) positioning reed (14) through the sliding pin (7) of axle sleeve (2) drive sheave (1) on connecting pin (11) connecting strap (5) and tooth piece (6) and is parked in new deciding in the retaining hole (15), and the tooth piece is equivalent to a new sprocket wheel.Dial retaining breach chute dish when motionless pushing down, pedal rotates forward and drives the tooth piece and move to the center, and sprocket wheel diminishes, and bicycle slows down, and moves to the outer like the pedal tooth piece that rotates backward, and it is big that sprocket wheel becomes, and bicycle quickens.Only draw one group of tooth piece among the figure, ratchet, the ratchet spring protects the chain sheet, sliding pin and connecting strap, its quantity equates with the chute number.
