Abstract
The utility model discloses an electric speed regulating device for a continuously variable transmission. Connected hydraulic cylinders are respectively installed on a driving moving wheel and a driven moving wheel, the hydraulic cylinders are filled with oil liquid, the driving moving wheel and the driven moving wheel are connected, and if the driving moving wheel is moved under the action of applied force, the driven moving wheel is moved reversely under the pressure of hydraulic oil. Since the balancing of pressure between the two cylinders is realized through the oil liquid pressure, only very small external force is consumed and the balancing can be changed, and the energy can be saved to the utmost extent. Since the axial movement of the driving moving wheel is pushed through the gear device, the working radius of the driving moving wheel is changed to achieve the purpose of continuous change. The utility model is easy to smoothly and continuously change speed.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, as can be seen, the electronic arrangements for speed regulation of stepless speed variator of the present utility model comprise case lid 1, driving shaft 2, driving wheel, driven shaft 3 and follower from the figure, driving shaft 2 and driven shaft 3 are installed in the case lid 1 by bearing 4 respectively, are provided with driving belt 5 between driving wheel and the follower.Driving belt can be metal tape or metal chain, or other is as rubber tape, and compound strip etc. are better with metal tape.
Described driving wheel is made up of active fixed wheel 6 and active driving wheel 7, and initiatively driving wheel 7 is a conical surface wheel, and initiatively fixed wheel 6 is fixed with driving shaft 2, and initiatively driving wheel 7 can slide along driving shaft 2.Follower is made up of driven fixed wheel 8 and driven driving wheel 9, and driven driving wheel 9 is conical surface wheel, and driven fixed wheel 8 is fixing with driven shaft 3, and driven driving wheel 9 can slide along driven shaft 3.Line belt 5 is located in the cone tank of the relative formation with driving wheel of fixed wheel.On driving shaft 2, be arranged with by change cylinder internal volume and drive the active driving wheel driving oil cylinder 10 that active driving wheel 7 slides along driving shaft 2, be provided with the electric driver mechanism 11 that changes active driving wheel driving oil cylinder volume in case lid 1, electric driver mechanism 11 is connected with active driving wheel driving oil cylinder 10 by driving mechanism.On driven shaft 3, be arranged with by change cylinder internal volume and drive the driven driving wheel driving oil cylinder 12 that driven driving wheel 9 slides along driven shaft 3.Be equipped with axial fluid passage 13 on described driving shaft 2 and the driven shaft 3, two fluid passages 13 are communicated with each self-corresponding driving oil cylinder by the mode of establishing oilhole 14 on axle, oil pipe 19 two ends are communicated with fluid passage 13 by pipe joint 15 and end cap 16 respectively, two oil cylinders, one side's volume reduce correspondence the increase of the opposing party's volume.
Electric driver mechanism is by such structural change driving wheel driving oil cylinder volume initiatively: be provided with leading screw 17 on driving shaft 2, leading screw 17 and secondary 18 engagements of gear nut, electric driver mechanism 11 by gear transmission (simultaneously slow down) thus actuation gear pair of nut 18 becomes gear nut pair 18 moving axially on driving shaft 2 rotating on the leading screw 17, secondary 18 1 ends of gear nut are connected with active driving wheel driving oil cylinder 10 cylinder bodies, to the left or to the right in the moving process, initiatively the volume of driving wheel driving oil cylinder 10 diminishes or becomes big in gear nut pair 18.
For preventing that oil liquid leakage from causing fluid to reduce, and is provided with oil pressure detector and slippage pump (not drawing among the figure) on oil circuit.
Working principle of the present utility model:
Among Fig. 1, motor rotates, and drives each gear corresponding the rotation taken place, and rotate thereby drive nut teeth wheel set 18, and it cooperates with leading screw 17.Leading screw 17 is fixed on the case lid 1 by driving shaft 2, so nut teeth wheel set 18 rotates on the one hand, move left and right takes place on the one hand.And it is connected with active driving wheel driving oil cylinder 10 by a series of devices, promotes or spurs this oil cylinder and moved axially into its main purpose.Oil cylinder moves and can cause oil pressure to change, thereby makes initiatively driving wheel 7 move left and right.When promotion active driving wheel 7 moved left, the belt wheel effective radius reduced.Initiatively oil chamber volume increases in the driving wheel driving oil cylinder 10, be pressed onto initiatively driving wheel driving oil cylinder 10 with the fluid in the driven driving wheel driving oil cylinder 12 by oil pipe 19 this moment, and driven driving wheel driving oil cylinder 12 internal pressures diminish, and driven driving wheel 9 moves to left, radius increases, and reaches the purpose of deceleration.Otherwise when the secondary pulling active of gear nut driving wheel driving oil cylinder, the driving wheel effective radius increases, and the oil cylinder internal volume reduces, and extrudes fluid and arrives in the driven driving wheel driving oil cylinder by oil pipe, and fluid increases, and it is big that pressure becomes.Promote driven driving wheel and move right, its effective radius reduces, and reaches the purpose of acceleration.The utility model is provided with helical spring, and its effect is when pressure oil stops to flow oil cylinder to be resetted.And on oil circuit, increase the pressure that the oil pressure detector detects fluid, a less slippage pump is installed is simultaneously replenished owing to oil circuit is revealed that part of oil that causes fluid to lose.
The utility model energy consumption is low mainly to be realized by gear train and hydraulic pressure installation.On active driving wheel and driven driving wheel, an oil hydraulic cylinder is installed respectively, is realized pressure balance between two cylinders, only need very little external force consumption just can change this balance, therefore can save energy, good economy performance to greatest extent by oil liquid pressure.Promote initiatively moving axially of driving wheel by gearing, reach infinite variable speed purpose thereby change its radius of clean-up.Hydraulic pressure installation is two continuous oil cylinders, and the centre is full of fluid, and the moving movable pulley of principal and subordinate is coupled together, and is moved if initiatively driving wheel is stressed, and then driven driving wheel also will be subjected to the pressure of hydraulic oil and take place oppositely to move.Gear train is made up of several sleeve gears and leading screw.Gear is used for realizing slowing down, and leading screw is used for making motion to change over from rotation and moves axially, and promotes the active driving wheel with him and is moved, and realizes that the change of radius reaches infinite variable speed purpose.
