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. It is inconvenient to maintain, another continuously variable transmission (CVT), which uses a metal transmission belt and a variable diameter driving and driven wheel to transmit power, but the weakness of CVT is that the metal belt has a small carrying capacity, limited transmission power, and high cost The service life is short, and its control system is quite complex, resulting in an increase in auxiliary costs. Currently, it can only be used in cars
The positive feedback rolling planetary gear stepless transmission of the present invention uses a positive feedback rolling planetary gear mechanism to realize stepless speed change, and can directly perform stepless variable torque and variable speed operation according to load changes during work, without the need for hydraulic and electric servo Mechanism, the present invention has no similar structural products and related materials at home and abroad

Abstract

The invention relates to a mechanical transmission, in particular to a positive feedback rolling planet gear continuously variable transmission used in a mechanical transmission system. The continuously variable transmission comprises a shell (1), an input shaft (2), an input intermediate wheel (3), a walking travel wheel (4), a walking gear ring (5), a front travel wheel rack (6), a front travel wheel shaft (7), a junction piece (8), a positive pressure gear (9), a feedback gear ring (10), a feedback travel rack (11), a rolling travel shaft (12), a rolling travel wheel (13), an output travel wheel (14), an output intermediate wheel (15), an output shaft (16) and the like. An output gear ring is rolled through a positive feedback rolling planet gear mechanism, so that the positive feedback rolling planet gear continuously variable transmission can output the highest torque during heavy load and also can output the highest rotating speed during light load; therefore, a function of mechanical continuously variable transmission is reliably realized. The transmission has a simple structure, high transmission ratio, high continuous bearing capacity and long service life and is low in price and safe and reliable.
