Description
Technical field
The utility model relates to the gear type change-speed box, and particularly bicycle pedals is controlled reciprocal shift transmission.
Background technology
Bicycle still is widely used in the modern life as economical, the easy vehicle.Existing bicycle shift system built-in variable speed still is that external speed change all is made up of change-speed box and actuation means two parts basically, is connected by control line.Necessary hand and pin while compounding practice and very careful during use are if firmly accidentally, be easy to cause fault or damage.Form subconscious psychological pressure and take sb's mind off sth unavoidably in when gearshift, become potential safety hazard.The front and back flywheel of outer speed change is also wanted corresponding simultaneously transposing, and operation is trouble more.And the change-speed box of external since each fly for a short time can not be in the optimal engagement state all the time with chain, so occur falling situation such as chain easily.
Summary of the invention
The purpose of this utility model is to relate to a kind of reciprocating type built-in self-locking speed change device of controlling by foot-operated revolution.
The technical solution of the utility model is: a kind of bicycle pedals is controlled reciprocal shift transmission mainly by the sealing oval-shaped shell 1 that is located at tread plate axis place, with the axis 2 that has spline, spline upper sleeve has sliding sleeve gear cluster 3, variable shaft 11 with different speed ratio gears, the finishing bevel gear cuter 15 of variable shaft left end, locating bush 7, finger 6, locking steel ball 9, lock ring 8, locating dowel pin 4, bearing 16, left end cap 15, right end cap (10) is formed, the right overcoat that it is characterized in that axis locating bush 7, the left side of locating bush reaches in the hole on sliding sleeve gear 3 the right, finger 6 one ends that are connected as a single entity with the sliding sleeve gear stretch out from the endoporus on sliding sleeve gear 3 the right, are inserted in the axial gradual change annular guide channel 17 that locating bush 7 cylindricals are provided with to constitute modified gear; Placed two locking steel balls 9 in two skewed slots on locating bush 7 the right, the lock ring 8 that is fixed on the right end cap 10 is overlapping formation derotation Locking Device; Be provided with a cross-drilled hole in the centre of axis, be placed with outwards two locating dowel pins 4 on top of spring 5 and two in the hole, be enclosed in endoporus and be provided with in the hole of sliding sleeve gear cluster (3) of circular groove and constitute detent mechanism.Axis is respectively equipped with bearing 16 with the two ends, the left and right sides of variable shaft and links to each other with left end cap 15 right end caps 10, and left and right end cap is fixed on the both sides of oval-shaped shell.Described a kind of bicycle pedals is controlled reciprocal shift transmission, it is characterized in that described gradual change loop turn groove and axially between angle more than or equal to 55 degree.
When normally riding, moment of torsion on the stretcher passes to sliding sleeve gear (3) by axis (2) by spline, see (figure d), gear on sliding sleeve is passed to variable shaft (11), again by the finishing bevel gear cuter on the variable shaft (12) by transmission shaft (14), moment of torsion is outputed to the finishing bevel gear cuter that trailing wheel flies for a short time, pass to the back engraved roll at last, promptly on the trailing wheel.
When pedal was motionless, by the unidirectional rotation locking effect that trailing wheel flies for a short time, bicycle can keep sliding.
When the needs speed change, only needing foot-operated is the axis counter-rotating, then also counter-rotating thereupon of sliding sleeve gear, finger on it drives locating bush and also reverses, in case locating bush reverses then can be stuck by the locking steel ball that lock ring is clamped, be lock ring by screw retention on right end cap, can not rotate, on locating bush, have two skewed slots of gradual change radially of symmetry, in groove, put into the locking steel ball, when axis and locating bush are just changeing, the locking steel ball has been brought to a side of groove depth, its gap is greater than the diameter of locking steel ball, and the locking steel ball can only skid in groove, and locating bush can just change with axis; When the counter-rotating of axis and locating bush, the locking steel ball has been brought to the shallow opposite side of groove, and the gap of bevel between lock ring and the locating bush becomes less than the diameter of locking steel ball, and the locking steel ball is stuck in wherein, causes the locating bush also just can not contrarotation.Promptly played and made locating bush can only just change the derotation locking effect of non-reversible unidirectional rotation.
Be processed with the cross section and be rectangle on the locating bush cylindrical and the axial annular guide channel of gradual change, this annular guide channel is the distance of three gears in axial displacement of staggering just.One end is fixed on the finger on the sliding sleeve gear, and the other end that inwardly stretches out just is inserted in this annular guide channel and slides.When axis drive sliding sleeve gear reverses together, also just counter-rotating thereupon of finger with sliding sleeve gear one, be inverted locking this moment and axially promotion is just made the finger of counter-rotating back and forth on the inclined-plane of fixed annular guide channel simultaneously, be that the sliding sleeve gear is by the displacement effect that axially back and forth promotes, make the variable shaft gear mesh of sliding sleeve gear, thereby realize gearshift voluntarily with different speed ratios.
In the endoporus of sliding sleeve gear, processed three road triangular ring positioning grooves, respectively corresponding in the axial direction three gears, by two locating dowel pins that spring two outwards ejects, can be at radial expansion.When annular positioning groove slipped over locating dowel pin, the tapered pin head of locating dowel pin just can spring in this groove, made the sliding sleeve location, reached the fixed purpose of gearshift.
Because on the locating bush is annular guide channel, as long as the sliding sleeve gear reverses, finger will drive sliding sleeve and move back and forth, and again because of the effect of locating dowel pin, makes gearshift accurately, and the sensation of gear is arranged on the stretcher, so just can realize the function that moves in circles and shift gears.
Advantage of the present utility model is only can realize variable-speed operating control by the personnel of riding to foot-operated revolution.Since adopt the built-in gear change of leak free, so it is compact conformation is reliable, cheap for manufacturing cost.
