V-type metal tape 11 is by a plurality of V-type metal push jacks 14 and two groups of high flexibility metal tapes that metal ring 15 is formed, under the active wheel extruding force effect of both sides, and the transferring power of coming in before pushing, the metal ring on both sides is formed by stacking by multi-layer thin steel band ring 16.In transmission, be mainly used to tinsel is constrained in together, and the motion of correct guide wire piece element.The characteristics of this band are to make the winding radius work that belt wheel can be minimum, and the speed ratio operating range is big, transmission of torque capacity height.
During main, passive oil cylinder high speed rotating, the liquid of main, passive oil cylinder is because action of centrifugal force produces kinetic pressure, this dynamic pressure will influence the accurate control to clamping force and speed ratio, therefore, the dynamic pressure that fluid produces when solving high speed is to the influence of control accuracy, and passive oil cylinder also adopts dynamic pressure to compensate and offsets action of centrifugal force.
Driving pulley oil cylinder and driving pulley connect into an integral body by bolt, and passive belt wheel oil cylinder and passive belt wheel connect into an integral body by bolt, and the driving pulley piston is fixed on the driving pulley axle, and passive belt wheel piston is fixed on the passive belt wheel shaft.
Propulsion steel strip type stageless transmission mechanism speed changer principle as shown in Figure 6.The variable part is made up of driving pulley 1, V-type metal tape 11 and passive belt wheel 6.
Every group of work belt wheel all is made up of two half cone wheels, and one of them half cone wheel is fixed, and is made of one with belt shaft, and another half cone wheel is controlled it by hydraulic jack and moved axially.The standing part of driving pulley axle and driving pulley is an one, is processed with the slideway that is used to lay steel ball on the driving pulley axle, and this steel ball slideway structure is used for driving pulley axle and movable cone pulley are fixed along circumferential.In the middle of the driving pulley axle oil supply gallery is arranged, flow is to actuating cylinder supply pressure oil in accordance with regulations.
The passive belt wheel shaft is accepted the power that the metal tape transmission comes.The standing part of passive belt wheel shaft and passive belt wheel manufactures one, is processed with the slideway that is used to lay steel ball on the passive belt wheel shaft, and this steel ball slideway structure is used for passive belt wheel shaft and movable cone pulley are fixed with same rotational speed along circumferential.In the middle of the passive belt wheel shaft two oil supply galleries are arranged, a fuel feeding that is used for passive cylinder is to realize the clamping force requirement; Another is used for to dynamic pressure compensating cylinder fuel feeding, with balance because the caused dynamic pressure of high speed rotating fluctuation.
Because the wheelbase of two belt wheels is fixed, the girth of metal tape also is a definite value, and the speed ratio during speed change can be expressed as: i=n
1/ n
2=r
2/ r
1Axial corresponding displacement between the half cone wheel is according to driver's the operation intention and the driving cycle of automobile, is controlled automatically by electric control device.In the process that driving pulley moves vertically, the driving pulley radius of clean-up is also changing.Because the girth of metal tape is certain, so the passive belt wheel radius of clean-up also takes place by corresponding the variation thereupon.What determine these a series of variations is the flow of Transmission Ratio Control valve, and when the amount of movement that requires when the amount of movement of active cylinder and gear ratio change reaches balance, the flow of Transmission Ratio Control valve will be zero (dam mouthful close).When the radius of clean-up r1 of driving wheel is in small radii (between radius apart from broad), the radius of clean-up r2 of driven wheel then is in than long radius (distance between radius is narrower), and the speed ratio of this moment is bigger, is equivalent to automobile underdrive and travels.Otherwise, be equivalent to top grade and travel.Pressure and hydraulic oil by the control hydraulic jack flow into (outflow) amount, and then the continuous variation of control r1 and r2, just can realize stepless change.That is: moving axially of promptly main, the passive belt wheel of the moving element by controlling main driven wheel changes the radius of clean-up of metal tape, just obtains the continually varying speed ratio.
Advantage applies of the present invention can continuously change gearratio, simple and compact for structure, handiness, transmission effect The rate height adapts to currently to automobile environment-protection, energy-conservation, comfortable requirement, has vast potential for future development.
