The present invention relates to the speed change field of automobile power output, the device that the application of the invention is designed can allow motor car engine can obtain different rotating speed output under same rotating speed, and this process is the continuity speed change.
Background technique
The gearbox of automobile belongs to the vitals of automobile, gearbox occupies very important position in the cost of automobile, there are two kinds of speed changers in existing automobile variable speed field: manual transmission and automatic transmission, and automatic transmission is divided into: electronic control manual transmission (AMT), hydraulic control automatic transmission (AT) and stepless speed variator (CVT).
Wherein, manual transmission is most widely used general, and common application is on all size type vehicle, and automatic transmission then is applied to dilly.
Manual transmission is provided with several groups of gears, and the contact that the driver respectively organizes gear by manual tune realizes the transmission of various ratios, and the use of engagement clutch simultaneously realizes the starting, acceleration of automobile etc.
Its core essence of electronic control manual transmission (AMT) is a manual transmission, it is on the basis of common manual speed changer, by installing the Electric actuator of microcomputerized control additional, replace block selecting, the gearshift action of separation, joint and the speed changer of the clutch that former cause manual operation finishes, realize self shifter.
Hydraulic control automatic transmission (AT) is made up of torque converter, planetary pinion and hydraulic control system, and the mode by fluid power transmission and Gear combination realizes the speed change bending moment.Wherein torque converter plays important effect in AT, and it is made up of members such as pump impeller, turbine and guide wheels, has the effect of transmitting torque and clutch concurrently.
Stepless speed variator (CVT) is compared with AT, saved complicated and heavy Gear combination speed change transmission, but two groups of belt wheels carries out the speed change transmission.Carry out speed change by the contact radius that changes driving wheel and follower driving belt.Owing to cancelled gear transmission, so its velocity ratio can random variation, and speed change is more smooth-going, not have the kick sense of shifting gears.
Summary of the invention
Sphere wheel stepless speed variator.Mainly comprise: power input shaft (1), input shaft fixing rod (2), constant velocity universal joint (3), sphere wheel running shaft (4), sphere wheel (5), turning lever (6), centering wheel (7), output shaft fixing rod (8), output shaft (9), follower lever (10), feature is: by sphere wheel (5) this device, by two sphere contact positions that the sphere round transformation is different, realize the variation of automobile rotational speed.
The invention a device that is called " sphere wheel ", by the variation of sphere wheel angle, change the contact position of two spheres wheels, thereby change the ratio in the transmission process, realized the gear ratio of any ratio in theory.This device mainly is made up of following parts:
One, sphere wheel: an end of this device is a sphere, can rotate to an angle around the centre of sphere of sphere, sphere again can be around the central shaft rotation of this sphere simultaneously, and the power of rotation is delivered to power input bar or power output rod by a constant velocity universal joint.
Two, drive link: comprise the power input and output, can can't harm transferring power.
Three, driving lever: the angle that can control the sphere wheel by the control driving lever.
Four, constant velocity universal joint: angle transferring power in the several angle rotation that can allow sphere take turns.

Embodiment
In Fig. 1, the power of motor can input to gearbox by this axle of power input shaft (1); Input shaft fixing rod (2) inside is hollow shape, and power input shaft (1) can be in the rotation of the inside of input shaft fixing rod (2); Turning lever (6) inside is similarly hollow shape, and the center of power input shaft (2) and fixing rod (6) intersects at the home position of sphere wheel (5); Constant velocity universal joint (3); Realize the transmission of input shaft (1) power when can change in the angle of sphere running shaft (4); Sphere wheel running shaft (4) can be around the central shaft rotation, sphere wheel (5) is fixedly connected on above the sphere wheel running shaft (4), therefore, and except can rotating around center line 1 direction, simultaneously can be around the centre of sphere of sphere wheel (5), in clockwise or rotation counterclockwise.
When the power of motor is connected to input shaft (1), by constant velocity universal joint (3) and sphere wheel running shaft (4), allow sphere wheel (5) also have one with the consistent rotating speed of input shaft (1) angular velocity, at this moment, two points of A and B because be positioned at sphere wheel above, so the two angular velocity unanimity, again because the radius of gyration of A and B correspondence is r1 and r2, r1＜r2, so the linear velocity of A is littler than the linear velocity of B, the ratio of the two is r2: r1.
Because can find out numerous point on sphere wheel (5), if the radius of sphere (5) is R, the engine power output speed is ω, then correspondence can find out (0, the R) point of any radius in the scope.Free-throw line speed in (0, the ω π R) scope of realization.
In Fig. 2, centering wheel (7) is positioned at the periphery of turning lever (6) and input shaft fixing rod (2) and output shaft fixing rod (8) and take-off lever (10), do not influencing under the situation of internal structure motion, can allow be in a good mood around the center of this device hour hands or counter clockwise direction of turning lever (6) and input shaft fixing rod (2) and output shaft fixing rod (8) and take-off lever (10) rotate; Output shaft fixing rod (8) principle and input shaft fixing rod (2) are similar, can allow output shaft (9) portion rotation within it, as the power output of automobile tire.
If the power output speed of motor is ω, then the rotating speed of sphere (5) is ω.Two sphere wheels intersect at the C point, radius corresponding to first sphere wheel is r3, second sphere wheel radius is r4, therefore, at first C point above sphere wheel, the linear velocity of this moment is ω π r3, and the C point that second sphere taken turns is because closely contact with the C point of first sphere wheel, so linear velocity is similarly ω π r3.But the C o'clock radius corresponding to second sphere wheel that second sphere taken turns is r4, and r4＜r3 is so the rotating speed that this moment, second sphere taken turns is ω r3/r4.
Because the C point can be infinitely close to the summit of sphere wheel, the radius of sphere wheel is R, and promptly the scope of r4 correspondence be that (0, R), so in theory, (ω ,+∞) rotating speed are taken turns and can be realized to second sphere.
In Fig. 3, turning lever (6) turns to present present position by inverse position clockwise shown in Figure 2, at this moment, two sphere wheels intersect at the D point, D point this moment pairing radius on first sphere is taken turns is r5, and pairing radius is r6 on second sphere wheel, r5≤r6.
If the power output speed of motor is ω, then the rotating speed that this moment, first sphere was taken turns is ω, is ω π r5 corresponding to the D point in the linear velocity of first sphere wheel, and the linear velocity at second sphere wheel was similarly ω π r5 in D o'clock, therefore the rotating speed of second sphere wheel is ω r5/r6, because r5 can be infinitely close to running shaft, promptly excursion be (0, R), therefore, the scope that the rotational speed omega r5/r6 of second sphere wheel changes be (0, ω], this rotating speed finally transfers out by output shaft (9).
In conjunction with Fig. 2 and Fig. 3, turning lever (6) can rotate clockwise or counterclockwise, if the rotating speed of motor is ω, the radius of sphere wheel is R, then can switch the angle of (6), allow (9) to obtain the rotating speed that changes in (0.+ ∞) scope, and the process of this rotation speed change, be totally continuous, this process is the infinite variable speed process of automobile gearbox.
