Problems solved by technology
[0002] At present, the automatic transmission technology that is widely used in automobiles is the combination of hydraulic torque converter and planetary gear train, and adopts automatic hydraulic and electric shifting AT technology, but it has obvious disadvantages: the transmission ratio is discontinuous, the hydraulic The transmission efficiency is low, the structure is complicated, and the maintenance is inconvenient. Another continuously variable CVT technology uses electronic automatic control of the variable working diameter of the main and driven wheels to cooperate with the metal transmission belt to transmit power, but the weakness of the CVT is the metal transmission. Belt load capacity is small, transmission power is limited, and the cost is high and the life is short. Its control system is quite complicated, resulting in an increase in auxiliary costs. Currently, it can only be used in cars.
The invention is the first to create a planetary ring gear clamp precession mechanism and use its clamp precession characteristics to control the drive output of the all-gear continuously variable transmission. During work, it can directly implement stepless transmission according to the change of the load force. Variable torque and variable speed operation, the present invention has not seen similar structure products and related materials at home and abroad

The invention relates to a mechanical transmission, in particular to an all geared infinitely variable transmission subjected to clamping procession by using a planetary gear ring in a mechanical transmission system. The all geared infinitely variable transmission mainly comprises parts such as an input shaft (1), a front input wheel (2), a front planet wheel (3), an output gear ring (4), an advancing wheel shaft (6), a driving frame (7), a driving middle wheel (8), a driving travel wheel (9), a clamping travel wheel (10), a planet carrier (11), a travel wheel shaft (12), a rear input wheel (13), a rear planet wheel (14), a clamping gear ring (15), a retreating wheel shaft (16), an output hub (17), an output shaft (18) and a shell (21), wherein output is controlled and driven through clamping procession characteristics of the clamping travel wheel (10) and the clamping gear ring (15), so that the highest rotation speed can be output after load is reduced while the maximum torque is output, thereby reliably finishing a mechanical infinitely variable transmission function by the all geared infinitely variable transmission. Thus, the all geared infinitely variable transmission has the advantages of simple structure, low cost, large transmission ratio and bearing capacity, safety, reliability and long usage period.
