Description
The utility model relates to the infinitely variable speed transmission of vehicle, especially is a kind of with the profile of tooth v belt transmission device of endless flexible element with the variable gear ratio conveying rotary motion.
(as: homemade Jiangling CJ50 II type) motorcycle on the existing scooter), the power of motor by centrifugal speed changer (speed change gear) send gear-box to, driving wheel advances motorcycle.This centrifugal stepless speed variator is to be provided with clutch, drive pulley on the crankshaft of motor, is provided with driven pulley on gearbox shaft, is the transmission of profile of tooth v belt between the driving and driven belt pulley.The height of this centrifugal belt stepless speed changing mechanism rotating speed is not along with extraneous road surface height, rough and uneven in surface situation (rolling resistance difference) changes, but change along with the variation of engine speed height, irrelevant with the extraneous resistance that motorcycle is suffered, for example, the motorcycle of this speed changer is installed, when descending, working resistance is little, do not walk (it is slower to mean the speed of a motor vehicle) but do not increase the throttle car, during upward slope, though the big throttle of working resistance increases car also unable (it is slower to mean the speed of a motor vehicle), throttle increases, the output power of car does not obviously increase, and nature will be wasted oil plant, the deficiency of Here it is this centrifugal stepless speed variator.
The purpose of this utility model is to overcome above-mentioned deficiency in the prior art, and provide a kind of follow-on change along with the extraneous change in resistance of motorcycle forward velocity can corresponding saving oil plant the motorcycle stepless speed change gear of Toothed belt transmission.
Task of the present utility model is finished by following approach.
Drive pulley is arranged on the crankshaft of motor, is made of fixed friction dish and mobile friction disk two-part.On the fixed friction dish, be provided with clutch.In mobile friction disk endoporus, be pressed with a lining, between the external diameter of the cannular boss of lining endoporus and fixed friction dish for movingly, mobile friction disk endoporus outer rim place is provided with spring, one end of the spring clamp that is fixed is keeping off, fixing chuck plate is fixed therein the end of sky boss by a nut, the end of fixing chuck plate is provided with wear-resistant block, and wear-resistant block can be along slide relative in the outer rim axial trajectory groove of mobile friction disk.
Driven pulley is arranged on the transmission case gear shaft, the outside of axle is fixed with bidirectional helical axle sleeve one with middle tool withdrawal groove place separately with the tapering of 1:5, a left side, right-hand member is respectively a single head left side, the dextrorotation trapezoidal thread, the left side of driven pulley, the endoporus that friction disk is moved in dextrorotation also is a single head left side, the dextrorotation trapezoidal thread, a left side, dextrorotation is moved the grinding disk endoporus and is matched with the bidirectional helical axle sleeve, left and right sides fixed tray is fixed by bolts to bidirectional helical axle sleeve two end part, a left side, respectively be provided with the small column of a fixing spring on dextrorotation friction disk and the left and right sides fixed tray respectively, a left side, respectively be provided with an oilhole and plug cock on the dextrorotation grinding disk respectively.
On the fixedly grinding disk of drive pulley, the left and right conical surface that is respectively equipped with 15 ° of angles on the grinding disk that revolves on the mobile grinding disk and in the driven pulley, forward and backward after both assemble respectively, just in time form the V-type groove at 30 ° of angles, so that the profile of tooth v belt is installed.
Performance and installation aspect to the axle spring in the mobile grinding disk in the drive pulley (stage clip) are to have certain requirements, diameter, the number of turn, the pitch of turn that is spring is that the length of spring and elastic force must guarantee under nature (when motor is not worked, when v belt is in state of rest), the spacing minimum (equalling zero) between fixed friction dish and the mobile friction disk just action radius between drive pulley and the belt is in maximum position.
In the driven pulley, spring (extension spring) is installed on the small column of mobile friction disk and fixed tray, when driving belt is static, after left and right two springs that revolve on the mobile friction disk install, should guarantee, revolve two spacing maximums (7mm) between the mobile friction disk about making, just the action radius between driven pulley and the belt is in minimum position.
The working principle of this stepless speed changes devices and working procedure:
When motorcycle is in halted state, just motor, when the transmission v belt is not all worked, mobile friction disk on the drive pulley under the stage clip effect with fixed friction dish spacing minimum, at this moment, the action radius maximum between drive pulley and the transmission v belt; And left and right in the driven pulley revolved mobile friction disk spacing maximum each other under the extension spring effect respectively, at this moment, criticizes action radius minimum between the band from belt pulley and transmission triangle.Behind engine start on the motorcycle, the clutch combination, when motorcycle begins to travel, the suffered resistive torque of car (moment of torsion of transmission case gear shaft) is during greater than minimal torque that extension spring on the driven pulley kept, then the transmission v belt drives a left side, dextrorotation is moved friction disk extension spring is elongated, make two to move the rotation of the relative bidirectional helical axle sleeve inhour of friction disk, two friction disk spacings are dwindled gradually, just the action radius between driven pulley and the belt increases (moment of torsion of keeping up to extension spring equals to stop when car travels required torque) gradually, because the centre distance between drive pulley and the driven pulley and the length of drivign belt are all certain, cause the mobile friction disk compression press spring on the drive pulley, the relative fixed friction disk is moved to the left, thereby the spacing between two friction disks is increased, just the action radius between drive pulley and the drivign belt diminishes, promptly main, transmission speed ratio between the driven pulley reduces, and the output torque of motorcycle increases.On the contrary, when the suffered resistive torque of the motorcycle driving moment of torsion that extension spring kept on less than driven pulley, then left in the driven pulley, dextrorotation two move friction disk respectively under the extension spring effect relatively the bidirectional helical axle sleeve turn clockwise, corresponding two move the friction disk spacing increases, just the action radius between driven pulley and the drivign belt reduces, and the mobile friction disk of drive pulley recovers under the effect of elastic force at stage clip, corresponding the diminishing of distance between its fixed friction dish and the mobile friction disk, just the action radius between drive pulley and the drivign belt increases, it is big that the transmission speed ratio of motorcycle becomes, rub and take off the car speed of travelling and increase, output torque diminishes, hence one can see that, the stepless speed changing mechanism that adapts to the motorcycle change in resistance changes along with the suffered extraneous resistance size of motorcycle, just this speed change gear can be realized: extraneous resistance is big, and transmission speed ratio reduces automatically, and the slack-off output torque of the speed of a motor vehicle increases; Extraneous resistance is little, and transmission speed ratio increases automatically, the car speed height that travels, and output torque diminishes.Like this, when also just having realized the motorcycle descending, need not increase throttle and the speed of a motor vehicle still keeps certain speed, and when going up a slope, because of extraneous resistance is big, output torque increases, and does not need to open the throttle very much, car is still felt effectively, and is guaranteed certain travelling speed.
