In device of the present utility model, belt supporting base with telescopic mast for being threaded.
The utility model is also settled spring between telescopic mast and adjustable arc ring.This spring can rely on elasticity that telescopic mast is withstood, and makes it to be adjacent to the chute inner face (inwall) of taper speed regulation seat.
The small end of the taper speed regulation seat of drive end is connected with pedal supporting base, on large end, quincunx end cap is installed; The small end of the taper speed regulation seat of driven end is connected with rear axle upper branching holder, on large end, quincunx end cap is installed.The large end that above-mentioned connection mode makes taper speed regulation seat, arranges quincunx end cap at large end outermost outwardly, can make device elegant in appearance.
In device of the present utility model, the uniform chute quantity that taper speed regulation seat arranges is vertically preferably 8 ~ 10, and uniform radial direction through hole, the axial uniform slideway of cylindrical slip cap etc. of belt supporting base, telescopic mast, adjustable arc ring, the telescopic mast coupling link supporting with chute quantity all equates with preferred chute quantity.Like this, can more guarantee belt stability of rotation on taper speed regulation seat, also more guarantee speed governing precisely and continuous electrodeless variation.Simultaneously also easy to process, simple in structure.
In fact whole stepless speed-regulating device of the present utility model is made up of three parts: control part, speed governing part and operating part.Control part is made up of universal driving lever, cylindrically coiled spring and sliding support cover, mainly completes and stirs the function such as belt and tightening belt.Speed governing part is made up of taper speed regulation seat, belt supporting seat, telescopic mast, spring, adjustable arc ring, telescopic mast coupling link, cylindrical slip cap, mainly realizes the step-less adjustment of speed.Operating part is made up of pedal Connection Block and belt, mainly realizes the input and output of power.
With respect to existing continuously variable unit, that this device has is simple and compact for structure, speed change sensitieness is good and speed governing precisely, level and smooth, continuously and the advantage such as stable.
