Description
technical field:
A kind of stepless speed changing mechanism, belongs to mechanical field variable transmission mechanism, the particularly automatic stepless speed-changing device of motor vehicle, weaving, mining machinery.
technical background:
Stepless speed variator is used in automobile industry, the metal band type stepless speed variator of present application is to change working diameter with the folding of two cone dishes, metal tape is made to only have two sides and cone dish friction driving like this, its moment transmitted is naturally limited, skidding is frequent, particularly when anxious acceleration; When the mobile cone dish on two axles moves, metal tape occurs crooked unavoidably, have lost power and has also damaged metal tape, then the stepless speed changing mechanism structure adding production is numerous and diverse, complex process, manufactures difficulty, expensive, can not realize large scale application.
summary of the invention:
Stepless speed changing mechanism goal of the invention of the present invention is: provide a kind of traditional belt wheel transmission mode, the position changing mobile support seat in the same way can change the diameter of wheel for inputting and output wheel, realize the stepless change of gear, mechanism is simple, easy to operate, easy to manufacture, with low cost, be convenient to the brand-new stepless speed changing mechanism of large scale application.
Stepless speed changing mechanism of the present invention is achieved in that by wheel for inputting, driving belt, output wheel, guide rail, large rivet, main support rod, dunnage, mobile support seat, splined shaft, clamp, little rivet, snap ring, set screw, fixing support seat, support guide groove and organization; Main support rod side is shaped with support guide groove; Mobile support seat is consistent with fixing support seat external structure, all leaves the recess of the ring matched with the rear portion annulus of main support rod above; Mobile support seat and fixing support seat concentric are arranged on splined shaft, and fixing support seat is fixedly mounted on splined shaft one end, and mobile support seat is moved on splined shaft by spline; Main support rod one end is shaped with circular hole, and it is hinged that two relative main support rods and guide rail lower central circular hole pass through large rivet, and it is hinged that the support guide groove on main support rod and guide rail two mother rib lateral rotundum pass through little rivet; Be actively coupled between recess and dunnage inside the main support rod the other end and mobile support seat or fixing support seat; Dunnage radial cylindrical setting-in clamp, clamp cylindrical fixed installation snap ring, snap ring is fixed by set screw; Connect wheel for inputting and output wheel in the guide groove that driving belt is inlaid in rail crown, splined shaft spindle nose and fixing support seat spindle nose connect with body activities; Fixing support seat on wheel for inputting and output wheel two splined shaft is antiparallel to be arranged on body; Wheel for inputting is made up of main support rod, fixing support seat, dunnage, large rivet, mobile support seat and support guide groove, and fixing support seat is arranged on splined shaft front end; Output wheel is made up of main support rod, fixing support seat, dunnage, large rivet, mobile support seat and support guide groove, and fixing support seat is arranged on splined shaft rear end.
The input shaft that stepless speed changing mechanism of the present invention is connected with power source, it there are mobile support seat and fixing support seat, the length of two wheel shape seats is consistent with external structure, all leaves the recess of the ring that several match with the rear portion annulus of main support rod above, and several dunnages; Mobile support seat concentric on splined shaft axle slides; Two main support rods are connected relatively, it places guide rail, the centre at the two ends, bottom of described guide rail, leave the circular hole connecting riveted joint slightly larger than main support rod, play the effect that restriction guide rail is movable; The two ends, left and right of guide rail are socketed with the support guide groove on main support rod again, the main support rod only having two to dock action simultaneously, support guide groove on it just can synchronously rise at guide rail two ends or decline, and ensure that the balance of guide rail is reliable, plays the effect of sharing moment of torsion simultaneously; Several main support rods relatively connected installing guide rail are put into two wheel shape support seats respectively, with the snap ring of inner side band shape recess cover thereon, like this with the semicircle recess of the recessed composition of the ring in support seat, add support seat surface toroidal surface, namely the major part of main support rod rear portion annulus has been encased, such layout allows main support rod obtain the strong support at rear portion, the slippage of main support rod when moving after preventing again mobile support seat.Several main steady arms and dunnage precision rely on, and have again and help with the support guide ledge of main support rod one, bear high pulling torque and be achieved; Output shaft is with the same layout of input shaft.Driving belt is placed in the guide rail of input shaft and output shaft, set up the connection of power transmission, when to adjust the axial distance of mobile support seat on diaxon simultaneously, several main support rods relatively connected on two axles, can the propping up or regain of scissors, the i.e. continual working diameter changing diaxon, velocity ratio is continual change thereupon, achieves stepless change.
Stepless speed changing mechanism beneficial effect of the present invention: structure is simple, easy to manufacture, overcome existing stepless speed variator skids frequent, and driving belt is easily crooked, the energy loss caused; Add the working life of driving belt; Simple to operate, with low cost.Be convenient to large scale application.
