Revolution gear ring continuously variable transmission

Abstract

The invention relates to a mechanical transmission, in particular to a revolution gear ring continuously variable transmission which is used in a vehicle drive system and utilizes a revolution gear ring to drive output. The revolution gear ring continuously variable transmission comprises main components of an input shaft (1), an input gear (2), the revolution gear ring (3), a coupling shaft (4), a drive gear ring (5), an output gear (6), an output shaft (7), a front gear ring frame (8), a rear gear ring frame (9), a coupling band (10) and a chassis (11). The revolution gear ring (3) drives the output gear (6) to slow down through rotation to output maximum torque; after load torque is reduced, the revolution gear ring (3) synchronously rotates along with the output shaft (7) in a revolution mode and continues to output the maximum torque at the same time to push the output gear (6) until the output shaft (7) outputs the highest rotating speed, and then the mechanical continuous variable-speed function is reliably achieved. The transmission is very simple in structure, low in cost, large in transmission ratio and continuous bearing force, safe, reliable, and long in service life.

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 utilizes the revolving ring gear continuously variable transmission driven by the revolving ring gear, which can directly change the load torque according to the load torque during operation, and realize the stepless speed change operation completely automatically. There is no similar structural product and related materials of the present invention at home and abroad.
