The output path of the present invention refers to a path through which the output power of the output element (22) passes through several elements and finally is outputted through the output shaft (6).

The reflux accelerating path of the present invention refers to the path through which the power output by the output element (22) passes through several components and finally to the speed increasing element (23).

The function of the return accelerating path is to increase the output speed of the output element (22) to the speed increasing element (23), and to increase the speed to a set value, thereby causing the speed increasing element (23) and the input element (21) When the input speed is increased at the output component (22), the rotational speed of the output element (22) can be continuously increased, and the repeated cycles of the shifting are continuously performed between the respective components, thereby causing each of the output path and the return accelerating path.

The set value refers to the ratio of the rotational speed between the speed increasing element (23) and the output element (22).

Due to the speed ratio between the speed increasing element (23) and the output element (22) in the return speed path of the present invention, the final ratio output shaft (6) of the present invention and the input shaft (1) will be determined. The ratio of the speed ratio, when the speed ratio between the speed increasing element (23) and the output element (22) and the power input by the engine are sufficiently large, the output shaft (6) and the input shaft (1) of the present invention can be realized. The speed ratio is infinitely increased, that is, the output speed can be steplessly and infinitely increased. Therefore, the ratio of the speed of the output shaft 6 to the drive train to the drive wheel can be selected to be sufficiently large, that is, set to an ultra-low speed. The gear, that is to say, the invention is capable of achieving stepless and infinite shifting.

The ratio of the rotational speed between the output element (22) and the input element (21) can be calculated from the following equations according to the actual situation. Calculated, can also be obtained from practice: W = (W1Z + Q) / (1 + K);

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

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

Z--- represents the speed ratio between the speed increasing element (23) and the output element (22), Z = n23 / n22, that is, the set value;

K--- represents the gear ratio between the ring gear or gear O23 and the sun gear O21, K = O23 / O21;

Q--- indicates that when the input element (21) is a sun gear, its value is 1; otherwise, its value is K.

It can be seen from the above formula that when the speed unit (2) selects the differential, that is, Q=1, K=1; when Z is less than 2, the W of the above formula can obtain the determined value; when Z is greater than or equal to 2 When the W of the above formula is an uncertain value, when the Z selection is greater than or equal to 2, the ratio of the rotational speed between the output element (22) and the input element (21), that is, the output shaft (6) and the input shaft (1) The speed ratio between them can be continuously increased infinitely, thus achieving infinite and stepless shifting.

When they are separated by several other elements, they can be connected together by several other elements in a hollow manner; the method of indirect connection means that two elements that need to be joined can be selected by adding a suitable transmission mechanism, a coupling shaft, a coupling bracket or a plurality of elements of the unidirectional element to connect them together; when the selection increases the use of the unidirectional element to connect them together, the output ends of the unidirectional element are respectively They are connected together and the input of the unidirectional element is coupled to the fixed element.

The transmission mechanism may select a planetary gear transmission mechanism, a small tooth difference transmission mechanism, a cycloidal pinion planetary transmission mechanism or a harmonic gear transmission mechanism, or may select various gear transmission mechanisms, a sprocket transmission mechanism and a pulley transmission mechanism. The transmission ratio of each transmission mechanism is designed and selected according to actual needs.

The input shaft (1), the speed unit (2), the hydraulic actuator (3), the output shaft (6), and the remaining components may be arranged in different spaces, that is, they may be on the same central axis, or On different central axes, at this point, the appropriate coupling method should be chosen according to their position.

The hydraulic actuator (3) can be selected from a hydraulic torque converter, a fluid coupling, a pressure motor and a hydraulic pump, and various types of electronically controlled or hydraulically controlled clutches.

The unidirectional element, ie the unidirectional element (7), the first unidirectional element (10) and the second unidirectional element (11) may A variety of different types of clutches are selected including, but not limited to, overrunning clutches, one-way clutches.

The function of the unidirectional element (7) is that since the input end (71) of the unidirectional element (7) is coupled to the fixed element, the steering is restricted, so that the steering of the speed increasing element (23) cannot be combined with the input element ( The steering of 21) is reversed; the first unidirectional element (10) and the second unidirectional element (11) function to: when the input speed of the second unidirectional element transmission (11) is higher than the first unidirectional element ( 10) When the input speed is reached, the input shaft (1) has no power directly transmitted to the hydraulic actuator (3).

Since the merging speed unit (2) and the hydraulic actuator (03) all have the above various different options, and the coupling method between the various elements of the present invention, there are many different options described above, so that a plurality of different combinations can be combined.
