Abstract
A differentially driven stepless speed-changing box is made up of several differentials. A gearing is used in the speed-changing box. The output shaft cans automatic stepless changing speed according to the condition of the resistance.
Description
The invention belongs to and a kind ofly rely on gear transmission to finish infinite variable speed gearbox fully.Can be widely used in the traffic tool and lathe etc. needs in the machinery of speed change.
Existing gearbox divides two kinds of step change and stepless change in mechanical transmission.Advantages such as there have utmost point speed change to have to be simple in structure, and driving force is big.But need manually-operable.And it is not steady at high speed transmission process medium speed.Though stepless change stable drive simple to operate, driving force are all smaller usually, energy loss is big., type steel ring cone separator type wheeled as friction-disc, taper and gear chain type stepless variable speed unit incompatibility are used for truck and the big machinery of driving force.
Though also useful torque converter and differential mechanism in high-grade car constitute the infinitely variable transmission of high-power transmission.For example Mazda Motor uses torque converter, satellite differential, and the gearbox that oil hydraulic pump and clutch constitute can be realized big power variable speed, but involve great expense, mechanism's complexity.Use maintenance, maintenance expenses height.And in transmission process, need circulating water cooling hydraulic oil, cause energy loss.
The present invention is directed to the shortcoming of above-mentioned various gearboxes, utilize the transmission principle of differential mechanism, with several differential cluster altogether, constitute the transmission system of gearbox.Make gearbox rely on gear transmission to finish big power variable speed fully.
In order to achieve the above object, need be with a plurality of differential mechanism combinations.Power is driven output shaft by two transmission approach respectively jointly by the differential mechanism separated into two parts.A part can make the output shaft high speed rotating, and another part slowly runs it.These two output pathways can rely on the automatic speed regulation mechanism that is installed in the gearbox to distribute rotating speed.Thereby change the rotating speed of output shaft.Speed regulating mechanism can be a damper, also can be other stepless speed variator.Can also use generator damping low speed output pathway, send electricity and pass to motor and be used to drive the high speed output pathway, or output shaft.
Because this gearbox uses gear transmission fully, so transmitted power is big, energy loss is little.Simple in structure, maintenance, easy to maintenance.Has gear-driven advantage.Again owing to realized stepless change having stable drive, infinite variable speed advantage such as simple to operate.So the present invention has overcome the shortcoming of stepless speed variator.
As figure; Plane structure chart for a kind of specific implementation method of the present invention.
Gearbox shown in the figure mainly is made of (3), (4), (5) three differential mechanisms.All respectively be with a gear on the semiaxis of each differential mechanism.Be used for the axle and the transmission of other parts.
Power directly drives axle (2) and simultaneously power is passed to differential (4) after input shaft (1) imports into.The power that passes to differential mechanism (4) is divided into two output pathways.Article one, passing to axle (6) passes to axle (8) again and passes to this process axis (10) of output shaft (12) through gear (11) again and can not rotate.Do not rotate with two differential mechanisms (3) and (5) of axle (10) engagement yet.Only reverse mutually power is spread out of by its two-semiaxle.Its axis (6) passes to axle (8) with power, the synchronization that axle (2) passes to power axle (12) and keeps spreading out of with axle (8).
Another output pathway is that the planet carrier of differential mechanism (4) does not change.Axle (6) does not rotate thereupon yet.Power passes to axle (10) rear driving two differential mechanisms (3) and (5).Axle (2) reverses mutually with the planet carrier of differential mechanism (3), makes output shaft (12) high speed rotating.Axle (8) this moment, differential mechanism (5) made axle (8) obtain higher rotating speed when rotating because axle (6) does not change.So can and axle (12) synchronous.
(7) are generators among the figure, drive it by axle (6) and rotate.So it has produced resistance to axle (6).The electricity that it sends passes to motor (9) live axle (10) by electric wire (13).
Be subjected to resistance when big at output shaft (12), the power that axle (1) passes to axle (10) is not enough to drive (3) and (5) two differential mechanisms, and the power that passes to spool (6) can slowly run output shaft by live axle (8).Just making the approach of output shaft (12) high speed rotating drive the transmission approach that unmoving axle (12) only makes it slowly run can change.Output shaft (12) just rotates with the speed the end of than.And the driving force on the axle (10) and the resistance of output shaft (12) also are balances.So when the resistance on the output shaft (12) began to reduce, axle (10) just began to rotate under the power-assisted of motor (9).The more little axle of resistance (10) just changes soon more, up to axle (6) since the damping function of generator (7) do not change.Power only drives output shaft by axle (10) and rotates.Be the maximum output speed of gearbox this moment.
Article two, the transmission approach is by generator (7) damping axle (6) and send electricity motivation (9) live axle (10) of powering and finish automatic speed regulation operation.Because the power on axle (6) and spool (10) is balance at any time, thus speed regulating mechanism not transferring power only need very little power just can operate.
These two transmission approach drive output shaft (12) simultaneously in the gearbox real-world operation.Can also any stepless speed variator be installed between axle (6) and (10) the speed regulating mechanism and do speed regulating mechanism except making of generator and motor.Also can only on axle (6), add damper and make speed regulator.If between axle (6) and (10), also can make gearbox become step change transmission with manual governing mechanism.
The present invention is not limited to above a kind of compound mode of using differential mechanism.As long as utilize the transmission principle of differential mechanism, power is divided into two output pathways, and drives output shaft jointly.Form transmission system with differential mechanism fully, all belong to scope of the present invention.
