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 continuously variable transmission system for flow distribution transmission of a permanent magnetic speed-regulating planet gear. The continuously variable transmission system is specifically composed of a main driving part composed of two combined planet gear rows, a planet row for controlling transmission, a permanent magnetic transmission mechanism and a mechanism for regulating the magnitude of a permanent magnetic transmission torque. The continuously variable transmission system is particularly suitable for regeneration braking systems of automobiles and urban railway vehicles and is structurally characterized by controlling a sun gear 7 of the planet row 26 to feed the torque back to an inner gear ring 15 of a rear planet row through a main driving element 10 and an auxiliary driving element 11 of a permanent magnetic transmission device under slip frequency.

Description

technical field [0001] The present invention relates to a permanent magnet speed-regulating planetary gear shunt transmission stepless transmission system, which utilizes the characteristics of a single-row planetary gear with two degrees of freedom to perform power splitting and merging, and realizes stepless changes in the speed ratio of the main transmission line movement. Part of the power of the main transmission branch is diverted, and it is transmitted to another branch of the main transmission through the control transmission part. The permanent magnet transmission is installed in the control transmission part, and the slip transmission of the permanent magnet transmission is used to release the inconsistency of the gear transmission during the stepless speed change. Synchronization, changing the transmission torque of the permanent magnet transmission part to achieve speed regulation, suitable for automobiles, energy-saving vehicles, new energy vehicles, urban rail veh...
