A main transmission mechanism of a permanent magnet and gear compound transmission continuously variable transmission

Abstract

The invention relates to a main transmission mechanism of a permanent magnet and gear combined transmission continuous variable transmission device. The main transmission mechanism is particularly composed of a main transmission part composed of two combined planetary gear rows, a permanent magnet coupler, a front planet row with guide-out shafts on two sides and a front planet frame. The main transmission mechanism is particularly suitable for being used as a transmission of an automobile and is structurally characterized in that the planet frame 11 for controlling the planet row 12 is an input element, input power is relevant to a driving element 8 of the permanent magnet coupler and a shaft 27, an adjusting element is an overrunning coupler 10, and the permanent magnet coupler is installed on two sides of a thin round plate 18. The main transmission mechanism of the permanent magnet and gear combined transmission continuous variable transmission is suitable for the field of automobiles, energy-saving automobiles, new energy automobiles, urban rail vehicles, wind electricity power generation systems, aircrafts, machine tools, industrial and mineral machinery, engineering machinery and the like.

Description

technical field [0001] The invention relates to a main transmission mechanism of a permanent magnet and gear compound transmission continuously variable transmission, which utilizes the non-contact characteristics of the permanent magnet transmission and realizes the purpose of small volume and compact structure when applied to planetary gear differential continuously variable transmission , using the characteristics of planetary gears with two degrees of freedom to divide and merge power, realize the stepless change of the speed ratio of the main transmission line movement, divide a part of the power of the main transmission branch, and pass it to the other branch of the main transmission by controlling the transmission part , use the permanent magnet slip transmission mechanism connected with the control transmission part to close the planetary gear differential transmission mechanism, change the transmission torque of the permanent magnet slip transmission mechanism to achie...

Problems solved by technology

[0002] The automatic transmission for automobiles mainly uses a hydraulic torque converter to achieve stepwise stepless transmission. However, the manufacturing precision of the hydraulic torque converter is high and the volume is large. Although it can realize transmission at a large speed difference, the efficiency is low, especially When running at low speed; the CVT for automobiles is based on the friction mechanism, generally metal belt or chain, the disadvantages are high material requirements, high manufacturing precision and low efficiency, although it can achieve the best match with the engine, but The overall fuel-saving effect is not obvious; another kind of automatic transmission for vehicles, AMT, is a mechanical automatic transmission. Its shifting quality and comfort need to be improved to meet the comfort needs of passenger cars. Passenger cars: There is a problem with the dual-clutch automatic transmission for vehicles, and power interruption will occur due to heat generation, so it is no longer popular in the market
