The input path of the invention, refers to: when engine start, input power is only transmitted to input element (21) by input shaft (1).

The outgoing route of the invention, refers to: by the power of output element (22) output through several elements, the path externally exported finally by output shaft (6).

The reflux raising speed path of the invention, refers to: by the power of output element (22) output by several elements, being eventually transferred into the path of raising speed element (23).

The effect in reflux raising speed path is: when the output revolving speed of output element (22) being made to be transmitted to raising speed element (23), can raising speed to setting value, to make the input speed of raising speed element (23) and input element (21) converge speed when output element (22), the revolving speed of output element (22) can be increased constantly, and the iterative cycles of speed change are constantly carried out between each element, to make the revolving speed of each element on outgoing route and reflux raising speed path constantly increase, stepless and ad infinitum speed change is externally realized eventually by output shaft (6).

The setting value, refers to: the rotating ratio between raising speed element (23) and output element (22).

Due in reflux raising speed path of the invention, rotating ratio between raising speed element (23) and output element (22), it will determine the size of the rotating ratio between final transmission ratio output shaft (6) and input shaft (1) of the invention, when the power of rotating ratio and engine input between raising speed element (23) and output element (22) is sufficiently large, the rotating ratio that can be achieved between output shaft of the invention (6) and input shaft (1) ad infinitum increases, the revolving speed exported can be stepless and unlimited raising, therefore, output shaft 6 and power train are transferred to the rotating ratio between driving wheel, it can choose enough big, it is arranged to the gear of Ultra-Low Speed, that is, the present invention can be realized stepless and unlimited speed change.

Rotating ratio between output element (22) and input element (21) can fall into a trap according to truth condition from following formula It calculates and obtains, can also be obtained from practice: W=(W1Z+Q)/(1+K)；

W--- indicates the rotating ratio between output element (22) and input element (21), W=n22/n21；

W1--- indicates the transient speed ratio between output element (22) and input element (21), W1=n22/n21；

Each element for needing to couple, can choose the method being directly connected to, or the method that selection is indirectly connected with；The method being directly connected to, refers to: two elements for needing to couple can choose and be directly connected to, them is made to link together；When they are separated by other several elements, other several elements can be passed through, them is made to link together by hollow mode；The method being indirectly connected with, refers to: two elements for needing to couple, can choose by increase suitable transmission mechanism, coupling spindle, hitch or and unidirectional element among several elements, so that them is linked together；When selection, which increases, so that them is linked together using unidirectional element, the output end difference of unidirectional element is in connection together, and the input terminal of unidirectional element couples with fixing element.

The transmission mechanism can choose planetary gear transmission mechanism, few tooth difference transmission mechanism, cycloidal-pin wheel planetary gearing mechanism or harmonic gear drive mechanism, also can choose various gear drives, chain wheel driving mechanism and belt wheel transmission mechanism.The transmission ratio of each transmission mechanism, design is selected according to actual needs.

The input shaft (1), the fast unit (2) of remittance, hydraulic transmission device (3), output shaft (6) and remaining each element can be arranged in different spaces, i.e. they can be in same central axis, either on different central axis, at this time, suitable coupling method should be selected according to their position.

The hydraulic transmission device (3) can select fluid torque-converter, fluid-flywheel clutch, pressure motor and hydraulic pump and various types of automatically controlled or hydraulic control clutch.

The unidirectional element, i.e. unidirectional element (7), the first unidirectional element (10) and the second unidirectional element (11) can be with Select various types of clutch comprising but it is not limited to freewheel clutch, one-way clutch.

The effect of the unidirectional element (7) is: since the input terminal (71) of unidirectional element (7) couples with fixing element, play limitation to turn to, prevents the steering of raising speed element (23) from opposite with the steering of input element (21)；The effect of first unidirectional element (10) and the second unidirectional element (11) is: when the input speed that the second unidirectional element passes (11) is higher than the input speed of the first unidirectional element (10), input shaft (1) is directly delivered to hydraulic transmission device (3) without power.

Fast unit (2), hydraulic transmission device (03) are converged all with above-mentioned a variety of different selections due to constituting; and the coupling method between each element of the present invention; all there are above-mentioned a variety of different selections; so a variety of different embodiments can be combined into; therefore; they are inevitable all in scope of protection of the claims; and following specific embodiments is some therein; that is, scope of protection of the claims of the invention include but is not limited to following specific embodiments.
