Problems solved by technology
[0002] At present, the automatic transmission technology that is widely used in automobiles is the automatic transmission technology that combines the hydraulic torque converter and the planetary gear train, but it has obvious disadvantages: the transmission ratio is discontinuous, the hydraulic transmission efficiency is low, and the structure is complicated. maintenance inconvenience
The present invention uses three sets of planetary gear rows to form a direct-acting planetary gear continuously variable transmission capable of outputting the maximum torque and the maximum speed when the load decreases, and can output the maximum torque required by the design to the gear train and the maximum speed The output gear trains are combined together to form a superimposed motion gear train. During the working process, the direct-acting planetary gear of the present invention can directly implement stepless torque variable speed and variable speed operation without external force system and hydraulic torque variable parts. Continuously variable transmission, there are no similar structural products and related materials at home and abroad

The invention relates to a mechanical continuously-variable transmission, in particular to a direct-acting planetary gear continuously-variable transmission which takes a planetary gear row as main work. The continuously-variable transmission comprises the components such as an input shaft (1), a planet carrier (2), a road wheel shaft (3), a feedback middle wheel (4), a driving road wheel (5), a driving gear ring (6), a displacement middle wheel (7), a displacement road wheel (8), a firm connecting component (9), a driving planet carrier (10), a first-level road wheel shaft (11), a second-level road wheel shaft (12), an anchorage middle wheel (13), a first-level road wheel (14), a second-level road wheel (15), an output gear ring (16), an output rack (17), an output shaft (18) and a shell (19). In the direct-acting planetary gear continuously-variable transmission, the driving road wheel (5) and the driving planet carrier (10) directly drive the whole wheel train to revolute at a low speed until the highest rotating speed is output when the load is light, and an external force system and a hydraulic torque component are not required; and therefore, the continuously-variable transmission has the advantages of simple structure, low price, continuous transmission, safety, reliability, large carrying capacity and long service life.
Description
technical field [0001] The invention relates to a mechanical transmission, in particular to a direct-acting planetary gear stepless transmission used in a transmission system with mechanical gears as the main work. Background technique [0002] At present, the automatic transmission technology that is widely used in automobiles is the automatic transmission technology that combines the hydraulic torque converter and the planetary gear train, but it has obvious disadvantages: the transmission ratio is discontinuous, the hydraulic transmission efficiency is low, and the structure is complicated. Inconvenient maintenance. Another continuously variable CVT, which uses a metal transmission belt and a variable working diameter of the main and driven wheels to transmit power, but the weakness of the CVT is that the metal belt has a small carrying capacity, limited transmission power, high cost and short life, and its control system Quite complicated, resulting in an increase in au...
