Problems solved by technology

[0002] At present, the continuously variable transmission mainly uses the friction transmission method, or the combination friction transmission method after power splitting. The friction transmission method is inefficient and large in size, such as the metal belt or chain friction type CVT used in automobiles. Compared with similar transmissions, the problem is that the size is large, and the power capacity is small, so it cannot be equipped with high-end cars (displacement > 4.0 liters). Increased volume and weight, complicating the mechanism and increasing the cost

Abstract

The invention relates to a permanent magnet flexible locking and controlling continuously variable transmission system. The system comprises a main transmission part which is assembled by two combined planetary gear rows, a planet gear serving as control drive, a planet gear serving as speed rising, permanent magnet flexible locking mechanisms, a permanent magnet transmission mechanism and a mechanism for adjusting the size of the permanent magnet drive torque. The system is suitable to a transmission of a car particularly. The system is characterized in that torque is fed back to a rear planet gear inner gear ring 14 from a drive element 7 and a driven element 8 through a permanent magnet transmission device by a sun gear 28 of a control planet gear 33, the torque is transmitted under the slip, and a speed rising planet gear inner gear ring 21 is locked by permanent magnet flexible locking mechanism 11, 12.

Description

technical field [0001] The invention relates to a permanent magnet flexible locking and control continuously variable transmission system, which has the characteristics of non-contact by using the permanent magnet force. When the planetary gear is used to realize coaxial deceleration, the flexible locking is in a high-speed rotating state and cannot be mechanically contacted. A component of the fixed planetary row enables it to realize the deceleration function, and utilizes the characteristics of two degrees of freedom of the planetary gear to perform power splitting and confluence, realize the stepless change of the speed ratio of the main transmission line movement, and divide a part of the power of the main transmission branch , through the control transmission part to another branch of the main transmission, the permanent magnet slip transmission mechanism connected to the control transmission part is used to close the planetary gear differential transmission mechanism, an...
