Abstract
A stepless speed change mechanism belongs to a speed change transmission mechanism in the mechanical field, and particularly relates to an automatic stepless speed change device of a motor vehicle. The stepless speed change mechanism comprises an input wheel, a transmission belt, an output wheel and a machine body and consists of a guide rail, a large rivet, a main support rod, a support plate, a movable support seat, a spline shaft, a clamp, a small rivet, a snap ring, a fixed screw, a fixed support seat and a support guide slot. The stepless speed change mechanism has the beneficial effects that the structure is simple, the manufacturing is easy, and the frequent slipping of a conventional stepless speed changer and the energy loss caused by the easy titling of t transmission belt can be overcome; and the service life of the transmission belt is prolonged; the operation is simple, and the cost is low. The stepless speed change mechanism is convenient to promote and apply in large area.
Description
Technical field:
A kind of stepless speed changing mechanism belongs to the mechanical field variable transmission mechanism, particularly the automatic stepless speed-changing device of motor vehicle, weaving, mining machinery.
Technical background:
Stepless speed variator has obtained using in automobile industry; The metal band type stepless speed variator of using now is that the folding with two awl dishes changes working diameter; Make metal tape have only two sides and awl dish friction driving like this; The moment of its transmission is limited naturally, and skidding is frequent, in the time of particularly anxious the acceleration; When the mobile awl dish on two axles moved, metal tape took place crooked unavoidably, had lost power and had also damaged metal tape, and the stepless speed changing mechanism structure that adds production again is numerous and diverse, and complex process is made difficulty, costs an arm and a leg, and can not realize large scale application.
Summary of the invention:
Stepless speed changing mechanism goal of the invention of the present invention is: a kind of traditional belt wheel kind of drive is provided; Change in the same way and move the diameter that the position of supporting seat can change 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 and contains wheel for inputting, driving belt, output wheel and body, is made up of guide rail, big rivet, main support rod, dunnage, mobile seat, splined shaft, clamp, little rivet, snap ring, set screw, fixing seat and the support guide groove supported supported; The main support rod side is shaped on the support guide groove; Move and support seat to support that with fixing seat external structure is consistent, all leave the recess of the ring that matches with the rear portion annulus of main support rod above; Move and support seat and the fixing seat concentric of supporting to be installed on the splined shaft, the fixing seat of supporting is fixedly mounted on splined shaft one end, moves and supports seat to move on splined shaft through spline; Main support rod one end is shaped on circular hole, and relative two main support rods and guide rail lower central circular hole are hinged through big rivet, and it is hinged that the support guide groove on the main support rod and guide rail two mother rib lateral rotundums pass through little rivet; The main support rod the other end is supported seat or is fixed movable connection the between a support inboard recess and the dunnage with mobile; Dunnage is cylindrical setting-in clamp radially, clamp cylindrical fixed installation snap ring, and snap ring is fixed by set screw; Driving belt is inlaid in the guide groove at guide rail top and connects wheel for inputting and output wheel, and the splined shaft spindle nose connects with the body activity with the fixing seat spindle nose of supporting; Antiparallel being installed on the body of fixing support seat on wheel for inputting and output wheel two splined shafts; Wheel for inputting by main support rod, fixing support seat, dunnage, big rivet, move and support seat and support guide groove to form that fixing support is installed in the splined shaft front end; Output wheel by main support rod, fixing support seat, dunnage, big rivet, move and support seat and support guide groove to form that fixing support is installed in the splined shaft rear end.
Stepless speed changing mechanism of the present invention is by the input shaft that is connected with power source; Have on it to move and support seat and the fixing seat of supporting; The length of two wheel shape seats is consistent with external structure, all leaves the recess of several rings that match with the rear portion annulus of main support rod above, and several dunnages; Move and support seat concentric on the splined shaft axle to slide; Connect two main support rods relatively, place guide rail on it, the centre at the two ends, bottom of said guide rail is left and is slightly larger than the circular hole that main support rod connects riveted joint, plays the effect that the restriction guide rail moves forward and backward; The right ends of guide rail again with main support rod on the socket of support guide groove; Have only the main support rod of two butt joints to move simultaneously; Support guide groove on it just can rise or descend at the guide rail two ends synchronously, has guaranteed that the balance of guide rail is reliable, plays the effect of sharing moment of torsion simultaneously; Several main support rods that connect relatively that install guide rail are put into two wheel shapes respectively support seat; Snap ring with inboard band shape recess overlaps on it; With the semicircle recess of supporting on the seat of the recessed composition of ring, add and support the seating face toroidal surface like this, promptly encased the major part of main support rod rear portion annulus; Such layout lets main support rod obtain the strong support at rear portion, has prevented the mobile slippage of main support rod when supporting to move behind the seat again.Several main steady arms with support that backplate is accurate to be relied on, have the support guide ledge with the main support rod one to help again, bear high pulling torque and be achieved; Output shaft is with the same layout of input shaft.Be placed on driving belt in the guide rail of input shaft and output shaft; Set up the connection of power transmission, when adjusting simultaneously when moving the axial distance of supporting seat on the diaxon, several main support rods that connect relatively on two axles; Can scissors prop up or regain; Be the continual working diameter that changes diaxon, the continual thereupon variation of velocity ratio has realized stepless change.
Stepless speed changing mechanism beneficial effect of the present invention: simple in structure, easy to manufacture, overcome existing stepless speed variator and skid frequently, and driving belt be prone to crooked, the energy loss that causes; Increased the working life of driving belt; Simple to operate, with low cost.Be convenient to large scale application.
