Description
Technical field
The claimed technology contents of the utility model belongs to automobile and uses the stepless variable transmission technique field.
Background technique
The stepless speed variator of automobile use at present extensively adopts the hydraulic type stepless speed changing mechanism.Its transmission part that adopts is a fluid torque converter.It causes that by the interaction of runner vane the mutual conversion of mechanical energy and liquid energy comes transferring power, is the transmission component that a kind of variation by the liquid moment of momentum changes torque, has the ability that stepless continuous changes speed and torque.Though it can pass to wheel reposefully with the mechanical energy of motor, and has good automatic adjusting and conformability, its efficient is low, manufacturing process is complicated, cost is high, volume is big.
Summary of the invention
Technical problem to be solved in the utility model just provides a kind of transmission efficiency height, and is simple and reliable for structure, makes the automobile stepless speed variator that user cost is low, volume is little.
The utility model is to solve technical problem by clutch, input belt wheel, output pulley, driving belt, the fixed mechanism that forms than gear train, power input shaft, pto, free wheel device.The power input shaft that is connected with the passive hub of clutch is that the driving gear on the continuously variable belt transmission power input shaft keeps engagement with fixed than the driving gear on gear train driving gear and the idler shaft respectively, driven gear on the idler shaft drives the input tape wheel shaft and rotates, fixed driven gear than gear train is installed on the output pulley axle that output pulley drives, is provided with free wheel device between the fixed main driven gear than gear train; Input belt wheel, output pulley all are divided into two-part along the recessed centerpieces of belt wheel, and the movable piece of a part for moving along axle axial, another part be only and the fixed block that rotates of wheel shaft servo-actuated; Fixing bearing on the axle sleeve of input belt wheel movable piece, be with a duplex tooth tube on the bearing, the axle sleeve of input tape wheel shaft and movable piece all is in the inner ring that is fixed on the screw insert on the housing, one group of gear ring of duplex tooth tube and screw insert engagement, another group gear ring and output gear engagement by the gear train of driven by motor.
Above mechanism, make machine operation by automotive controls, motor makes between duplex tooth tube and the screw insert by gear train and produces relative movement, thereby the movable piece that makes the input belt wheel is realized along the input shaft axial motion, so just oppressing driving belt moves up and down, thereby change the drive wheel radius, realize stepless change.Because the band transmission is skidded easily, thereby cause its starting performance poor, for overcoming this defective, the utility model is overcome by being provided with by the fixed auxiliary driving route that constitutes than gear train and free wheel device, promptly when vehicle starting, free wheel device makes fixed main driven gear engagement locking than gear train, realizes that gear is surely than transmitting torque, free wheel device makes the main driven gear disengagement be free state when the output speed of being with transmission is enough big, utilizes band transmission shifting mechanism transmitting torque fully.
For overcome the band transmission as far as possible some such as defective such as skidding, the driving belt life-span is short, the utility model adopts following optimisation technique scheme: driving belt is formed by pushing piece and by the adhesive tape that rubber layer that is provided with stiffening rib and outsourcing resin layer constitute, pushing piece is worker's shape pushing piece, worker's shape pushing piece is made of aluminum alloy chip and outsourcing resin layer, and two adhesive tape interlockings are in the both sides breach of worker's shape pushing piece.The structure of this driving belt can life-saving, helps transmitting bigger moment of torsion, is difficult for skidding the transmission efficiency height.On the movable piece exterior edge face of output pulley holddown spring is arranged in addition, so no matter how the movable piece of output pulley moves, it is subjected to the strength that inwardly compresses all the time, can make input, output pulley keep being synchronized with the movement all the time and reducing and compress driving belt in the output pulley, reach the purpose that prevents drive belt slip.
The utility model is owing to some main drawbacks that the structure that is pure machinery of employing and optimization thereof overcomes the band transmission realize infinite variable speed, therefore compare with the hydraulic type stepless change, obviously has the transmission efficiency height, simple and reliable for structure, volume is little, make the low characteristics of user cost, structure of the present utility model has also possessed the advantage of driving flexibly, hanging down oil consumption, low noise simultaneously; Power character, fuel economy, driving comfortability, the run smoothness of automobile have been improved significantly; The utility model also can be realized the Comprehensive Control of power transmission system in addition, can give full play to engine characteristics.More good than transmission performances such as hydraulic type gear bearing capacity, slewing range, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is optimal way structural representation of the utility model.
Fig. 2 is the driving belt structural representation.
As Fig. 1, the driving gear 4 of the continuously variable belt transmission power input shaft 3 that is connected with the passive hub 2 of clutch 1 keeps engagement with fixed than the driving gear on gear train driving gear 5 and the idler shaft 23 22, driven gear 21 on the idler shaft 23 drives input tape wheel shaft 20 and rotates, fixed driven gear 7 than gear train is installed on the output pulley axle 9 that output pulley 12 drives, and fixed driving gear 5 than gear train is connected with input, the output member of free wheel device 6 respectively with driven gear 7.When the automobile low speed start, free wheel device 6 makes fixed driving gear 5 and driven gear 7 engagements than gear train, and the torque of motor is delivered on the hub for vehicle wheel assembly 8 than gear train by fixed; And the rotating speed of output pulley axle 9 is when accelerating gradually, and free wheel device breaks away from fixed driving gear 5 and driven gear 7 than gear train, and the torque of motor is delivered on the hub for vehicle wheel assembly 8 by output pulley axle 9 by belt transmission system.
Input belt wheel 19, output pulley 12 be divided into the movable piece that can move along axle axial and only with fixed block two-part of wheel shaft servo-actuated rotation, two-part junction is the trough of belt 25 of driving belt 13.Fixing bearing 17 on the axle sleeve 16 of input belt wheel 19 movable pieces 14, be with a duplex tooth tube 24 on the bearing 17, the axle sleeve 16 of input tape wheel shaft 20 and movable piece 14 all is in the inner ring of the screw insert 15 that is fixed on the housing, one group of gear ring of duplex tooth tube 24 and screw insert 15 engagements, output gear 18 engagements of another group gear ring and the gear train that drives by direct current generator 26.By the transmission of direct current generator 26, the driving link 14 that can make silk braid 15 drive the input belt wheel moves axially, and press belt 13 slides up and down, thereby the belt wheel radius is changed, and realizes stepless change.On movable piece 11 exterior edge faces of output pulley 12 holddown spring 10 is arranged.
